Description
Vynález sa týka spôsobu a formy na tvarovanie lisovaním za tepla, vhodného hlavne na tvarovanie predmetu, ako je napríklad prvok vnútorného obloženia dverí auta, obsahujúceho najmenej jednu silne deformovanú oblasť a získaného spojením, pri lisovaní za tepla, tepelne deformovateľného tuhého nosného plošného dielu a ohybného dekoračného povlaku.BACKGROUND OF THE INVENTION The present invention relates to a method and a mold for thermoforming, particularly suitable for forming an object, such as a car door trim comprising at least one heavily deformed region and obtained by joining, in thermoforming, thermally deformable rigid support and flexible. decorative coating.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Je dobre známe, predovšetkým z patentových spisov USA č. 4 243 456 a 4 328 067, vytvárať diely obloženia, ako sú diely vnútorného obloženia dverí áut, ktoré sú tvorené tvarovo prispôsobeným tuhým nosičom, ako je kovový nosič alebo termoplastická, eventuálne plnená hmota, vybaveným povlakom ohybného dekoračného prvku, ako je textília alebo umelá koža. Spravidla, predovšetkým z ekonomických dôvodov, sa spojenie lepením alebo zvarovaním medzi nosičom a povlakom vykonáva súčasne s tvarovaním nosiča ťahaním alebo lisovaním za tepla.It is well known, in particular from U.S. Pat. Nos. 4,243,456 and 4,328,067 to form lining parts, such as interior door trim panels, which are formed by a rigidly shaped rigid support, such as a metal support or a thermoplastic or filled material, coated with a flexible decorative element, such as fabric or artificial leather. As a rule, especially for economic reasons, the bonding or welding between the carrier and the coating is carried out simultaneously with the shaping of the carrier by hot-pressing or hot pressing.
Podľa bežne používaných postupov sa rovinný nosný plošný diel, eventuálne predhriaty a/alebo vopred polepený, a poddajný dekoračný prvok pridržiavaný na okrajoch rámom, vkladajú medzi matrice formy a tvarujú sa a súčasne spájajú uzatvorením formy.According to commonly used methods, a planar support sheet, possibly pre-heated and / or pre-glued, and a pliable decorative element held at the edges by the frame are inserted between the mold dies and are molded and simultaneously joined by closing the mold.
V prípade, keď sa týmto postupom vyrábajú diely ako napríklad diely vnútorného obloženia dverí áut, musí rovinný nosný plošný diel byť v určitých oblastiach silne deformovaný, napríklad na vytvorenie opierky na lakeť, a v dôsledku toho sú pri tvarovaní zodpovedajúce oblasti dekoračného povlaku vystavené silným preťaženiam, ktoré môžu viesť k určitému zmačknutiu dekoračného povlaku, a v dôsledku toho vo svojom výsledku k hotovému výrobku, ktorý je neestetický alebo menej pohodlný. Predovšetkým, ak sa na takéto výrobky používajú dekoračné povlaky vypchávaného typu, ako sú napodobeniny kože podložené penovou plastickou hmotou alebo velúry s hustým vlasom, zisťuje sa, že tento typ povlaku stráca v silne deformovaných miestach hotového výrobku svoj mäkký omak.When parts such as car door trim panels are produced by this process, the planar support sheet must be strongly deformed in certain areas, for example to form an elbow rest, and are consequently subjected to severe overloads during shaping, which may lead to some creasing of the decorative coating and, as a result, to a finished product that is unesthetic or less comfortable. In particular, when padded-type decorative coatings, such as foamed leather imitation leather or thick pile velor, are used for such products, it is found that this type of coating loses its soft feel at the strongly deformed areas of the finished product.
Vynález si preto kladie za úlohu vytvoriť spôsob a formu uspôsobené tak, aby umožnili výrazne znížiť tento nedostatok.It is therefore an object of the present invention to provide a method and form adapted to significantly reduce this drawback.
Podstata vynálezuSUMMARY OF THE INVENTION
Uvedený cieľ je dosiahnutý spôsobom tvarovania lisovaním predmetu, majúceho najmenej jednu silne deformovanú oblasť, tvoreného tuhým nosným plošným dielom deformovaným za tepla a dekoračným ohybným povlakom, ktoré sú navzájom spolu spojené, ktorého podstatou je, že napätý povlak sa vloží medzi vnútornú zasúvaciu matricu a vonkajšiu matricu otvorenej formy na tvarovanie za tepla pod tlakom, ktorej tvarovacie plochy zodpovedajú tvaru vyrábaného predmetu, potom sa povlak predtvarováva aspoň v miestach uvedenej najmenej jednej silne deformovanej oblasti núteným pritláčaním aspoň k časti jednej z tvarovacích plôch, a povlak sa pri tejto časti pridržiava, načo sa medzi tvarovacie plochy otvorenej formy vloži predhriaty nosný plošný diel, a forma sa uzavrie, čím sa uskutoční definitívne tvarovaniu vyrábaného predmetu a vytvorí sa spojenie medzi nosným plošným dielom a predtvarovaným dekoračným povlakom.This object is achieved by a method of molding an article having at least one strongly deformed region, consisting of a rigid, hot deformed support sheet and a decorative flexible coating which are connected to each other, the principle being that the tensioned coating is inserted between the male insertion die and the female then, the open die for a thermoforming die having shaping surfaces corresponding to the shape of the article being produced, the coating is preformed at least at the locations of the at least one strongly deformed region by forcing it to at least a portion of one of the shaping surfaces; a preheated support sheet is inserted between the molding surfaces of the open mold, and the mold is sealed, thereby definitively shaping the article to be made and forming a connection between the support sheet and the preformed decorative coating.
V dôsledku oddelenia procesov tvarovania povlaku v silne deformovaných oblastiach a spájania nosného plošného dielu a dekoračného povlaku možno konštatovať, že povlak zachováva svoje vlastnosti a predovšetkým svoj omak v silne deformovaných miestach vyrábaného predmetu.Due to the separation of the processes of forming the coating in the heavily deformed areas and the joining of the support sheet and the decorative coating, it can be stated that the coating retains its properties and, in particular, its feel at the heavily deformed points of the article to be produced.
V spôsobe podľa vynálezu sa dáva prednosť používaniu tepelne deformovateľných nosných plošných dielov, vyrobených na báze zmesí polyolefmov a drevených častíc alebo drevených pilín, aké sú opísané hlavne v patentovom spise USA č. 4 228 116, aleje zrejmé, že spôsob podľa vynálezu je použiteľný i na iné typy nosných plošných dielov.In the method according to the invention, it is preferred to use thermally deformable carrier sheets made on the basis of mixtures of polyolefins and wood particles or sawdust, as described in particular in U.S. Pat. No. 4,228,116, but it is clear that the method of the invention is applicable to other types of carrier sheets.
Použitý dekoračný povlak môže byť akýkoľvek, ale spôsob podľa vynálezu sa ukazuje obzvlášť účinný, keď ide o povlaky mäkkého podloženého typu, ako sú napodobeniny kože alebo prírodné alebo syntetické textilie s podkladom z termoplastickej hmoty a bunkovitou štruktúrou (polypropylény, polyuretány, atď.) alebo velúry s hustým vlasom.The decorative coating used may be any, but the method according to the invention proves particularly effective when it comes to coatings of a soft backed type, such as leather imitations or natural or synthetic textiles with a thermoplastic base and cell structure (polypropylenes, polyurethanes, etc.) or velor with thick hair.
Predtvarovanie dekoračného povlaku môže byť dosahované akýmkoľvek vhodným prostriedkom. Môže sa tak dosahovať fúkaním na stranu opačnú proti tej, ktorá má byť pritlačená aspoň k časti jednej z tvarovacích plôch alebo satím vyvíjaným smerom na túto tvarovaciu plochu. V týchto prípadoch sa môže ukázať ako užitočné pri použití povlakov, ktoré sú priepustné, keď sa plocha povlaku opačná proti ploche privrátenej k tvarovacej ploche, na ktorej sa vykonáva predtvarovanie vybaví v miestach deformácií znepriepustnením.The preforming of the decorative coating may be achieved by any suitable means. It can thus be achieved by blowing to the side opposite to that which is to be pressed against at least a portion of one of the shaping surfaces or by a suction applied towards the shaping surface. In these cases, it may prove useful in the use of coatings that are permeable when the surface of the coating opposite to the surface facing the shaping surface on which the preforming is performed is rendered impermeable at the deformation points.
V prednostnom vyhotovení môže byť predtvarovanie dekoračného povlaku dosahované prostredníctvom najmenej jedného pohyblivého nástroja, uloženého v druhej tvarovacej ploche formy.In a preferred embodiment, the preforming of the decorative coating can be achieved by means of at least one movable tool mounted in the second molding surface of the mold.
Sú použiteľné i ďalšie prostriedky, ako napríklad použitie vhodného robota.Other means, such as the use of a suitable robot, are also useful.
Predtvarovanie dekoračného povlaku sa môže taktiež dosiahnuť dočasným uzatváraním formy, ale v tomto prípade je tento povlak deformovaný na celom svojom povrchu.The preforming of the decorative coating can also be achieved by temporarily closing the mold, but in this case the coating is deformed over its entire surface.
Pridržiavanie predtvarovaných oblastí dekoračného povlaku na požadovanom mieste sa môže dosiahnuť predovšetkým iba vlastnou tiažou, keď je tvarovacia plocha, ku ktorej sa prikladajú predtvarované časti, dolná tvarovacia plocha, satím cez tvarovaciu plochu, ku ktorej je priložený, alebo akýmkoľvek provizórnym mechanickým ukotvením (provizórnym lepidlom, háčikmi, zavesovacou tkaninou, atď.), na časti tvarovacej plochy, ku ktorej sa prikladá predtvarovaná časť alebo časti dekoračného povlaku.Retaining the preformed areas of the decorative coating at a desired location can be achieved, in particular, only by gravity when the molding surface to which the preformed parts are attached is the lower molding surface by suction through the molding surface to which it is applied or by any temporary mechanical anchoring (temporary adhesive , hooks, hanging fabric, etc.) on a portion of the molding surface to which the preformed portion or portions of the decorative coating is applied.
Po predtvarovaní dekoračného povlaku sa nosný plošný diel, eventuálne predhriaty na vhodnú teplotu, ručne alebo mechanicky vkladá medzi matrice formy, a tvarovanie tohto nosného plošného dielu a jeho spájanie s dekoračným povlakom sa tak môže uskutočňovať klasickým spôsobom pomocou uzavretia formy.After the decorative coating has been preformed, the support sheet, possibly pre-heated to a suitable temperature, is inserted manually or mechanically between the mold dies, and the shaping of the supporting sheet and its joining with the decorative coating can thus be carried out in a conventional manner by closing the mold.
Spôsob podľa vynálezu sa ukazuje obzvlášť vhodný na vytváranie vnútorných obložení dverí áut, ale môže byť samozrejme zužitkovaný na výrobu akéhokoľvek dekoračného alebo úžitkového predmetu majúceho silne deformované oblasti.The method according to the invention proves particularly suitable for forming interior car door linings, but can of course be utilized for the production of any decorative or utility article having heavily deformed areas.
Vynález sa rovnako týka formy na tepelné tvarovanie pod tlakom na vykonávanie uvedeného spôsobu, ktorá sa vyznačuje tým, že obsahuje vnútornú zasúvaciu matricu a vonkajšiu matricu, vybavené prostriedkami na predtvarovanic dekoračného povlaku a jeho pridržiavanie v silne deformovaných oblastiach na aspoň časti tvarovacej plochy jednej z matríc pred vložením nosného plošného dielu medzi matrice.The invention also relates to a mold for thermoforming under pressure for carrying out the method, characterized in that it comprises an inner insertion die and an outer die provided with means for preforming the decorative coating and holding it in strongly deformed areas on at least a portion of the shaping surface of one of the matrices. before inserting the support sheet between the dies.
Na umožnenie realizácie prednostného uskutočnenia spôsobu podľa vynálezu sú prostriedky na predtvarovanie dekoračného povlaku výhodne tvorené aspoň jedným pohyblivým nástrojom uloženým v jednej z tvarovacích plôch formy.To enable a preferred embodiment of the method according to the invention to be carried out, the means for preforming the decorative coating are preferably formed by at least one movable tool mounted in one of the molding surfaces of the mold.
Prehľad obrázkov na výkresochBRIEF DESCRIPTION OF THE DRAWINGS
Vynález je bližšie vysvetlený v nasledujúcom opise na príkladoch vyhotovenia s odvolaním na pripojené výkresy, v ktorých znázorňuje:The invention will be explained in more detail in the following description by way of example with reference to the accompanying drawings, in which:

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Ako je zrejmé z výkresov, forma na lisovanie za tepla obsahuje vonkajšiu matricu 1, ktorej tvarovacia plocha 2 má veľmi ustupujúcu oblasť 3, tvarovo zodpovedajúcu opierke vnútorného obloženia dverí auta na lakte, ktoré sa majú vyrobiť, a vnútornú zasúvaciu matricu 4, ktorej tvarovacia plocha 5 zodpovedá tvaru vonkajšej matrice. Časť tvarovacej plochy vnútornej matrice 4, zodpovedajúca veľmi ustupujúcej oblasti 3 vonkajšej matrice 1, je tvorená pohyblivým nástrojom 6, uloženým vo vnútornej matrici 4, pričom posun tohto nástroja v zvislom smere je ovládaný pracovným valcom 7.As can be seen from the drawings, the thermoforming mold comprises an outer die 1 whose shaping surface 2 has a very recessing area 3, corresponding in shape to the inner door trim of the car door on the elbow to be produced, and an internal male die 4 whose shaping surface 5 corresponds to the shape of the outer matrix. A portion of the shaping surface of the inner die 4 corresponding to the very recessing region 3 of the outer die 1 is formed by a movable tool 6 housed in the inner die 4, the vertical movement of the tool being controlled by the working roller 7.
Veľmi ustupujúca oblasť 3 tvarovacej plochy vonkajšej matrice 1 je okrem toho vybavená prísavnými kanálmi 8, ktoré môžu byť spojené s vhodným neznázomeným zdrojom vákua.In addition, the highly recessed area 3 of the molding surface of the outer die 1 is provided with suction channels 8 which can be connected to a suitable vacuum source (not shown).
Prídavné môžu byť vnútorná a vonkajšia matrice vybavené prostriedkami 9, 10, dovoľujúcimi správne polohové ustavenie deliacej línie dekoračného povlaku v prípade použitia povlaku, ktorý je vytvorený z dvoch rôznych vopred spojených materiálov alebo materiálov, vyznačujúcich sa dvoma odlišnými znakmi povrchu.In addition, the inner and outer matrices may be provided with means 9, 10 permitting the correct positioning of the dividing line of the decorative coating in the case of a coating which is formed from two different pre-bonded materials or materials characterized by two different surface features.
V polohe znázornenej na obr. 1, je do otvorenej formy len vložený dekoračný povlak 11, ktorý je udržiavaný v napnutom stave prostredníctvom vhodného rámu 12.In the position shown in FIG. 1, only the decorative coating 11 is inserted into the open mold, which is held taut by a suitable frame 12.
V polohe znázornenej na obr. 2 je dekoračný povlak 11 podľa vynálezu najprv predtvarovávaný v uvedenej veľmi ustupujúcej oblasti 3 provizórnym a riadeným posunutím pohyblivého nástroja 6 prostredníctvom jeho ovládacieho pracovného valca 7. V polohe znázornenej na obr. 3 je nástroj 6 vrátený do svojej východiskovej polohy prostredníctvom pracovného valca 7, zatiaľ čo predtvarovaná časť dekoračného obkladu 11 je pridržiavaná v uvedenej veľmi ustupujúcej oblasti 3 vonkajšej matrice formy tým, že nasávacie kanále 8 sú pripojené k zdroju vákua.In the position shown in FIG. 2, the decorative coating 11 according to the invention is first preformed in said highly recessing region 3 by temporarily and in a controlled manner moving the movable tool 6 by means of its operating working roller 7. In the position shown in FIG. 3, the tool 6 is returned to its starting position by means of the working roller 7, while the preformed portion of the decorative cladding 11 is held in said highly recessed region 3 of the external mold die by the suction channels 8 being connected to a vacuum source.
V tejto polohe sa teraz môže do formy na tvarovanie za tepla vložiť nosný plošný diel 13, predhriaty a ukladaný mechanicky, napríklad prostredníctvom neznázomeného pásového dopravníka.In this position, the support sheet 13, preheated and mechanically deposited, for example by means of a belt conveyor (not shown), can now be inserted into the thermoforming mold.
V polohe znázornenej na obr. 3 stačí uzatvoriť formu vzájomným prisunutím vnútornej zasúvacej matrice 4 a vonkajšej matrice 1 na požadované prispôsobenie vyrábaného vnútorného obloženia dverí, ktorým sa vykoná úplné tvarovanie nosného plošného dielu 13 a dekoračného po vlaku 11, a vzájomné spojenie medzi týmito dvoma prvkami.In the position shown in FIG. 3, it is sufficient to close the mold by sliding the inner insertion matrix 4 and the outer matrix 1 together to suit the desired interior door trim to be completely molded to form the support panel 13 and the decoration on the train 11, and to connect them together.
