Definitions
- the present invention relates to a method for producing a storage part with an anti-slip covering according to the preamble of claim 1.
- Such a method of manufacturing a shelf e.g. a tray is known from DE 44 17 871 AI.
- an anti-slip layer is applied to a carrier film and introduced into the injection mold by means of the carrier film.
- the anti-slip layer is then back-injected with a plastic that forms the tray body and bonds firmly and permanently to the anti-slip layer.
- the molded part is removed from the mold, the carrier is then pulled off the anti-slip layer and wound up on a winding roll.
- a backing film must first be provided with the anti-slip layer, an adhesion promoter being provided between the backing film and the anti-slip layer must be made, which enables a later detachment of the carrier film.
- the carrier film After the molding process, the carrier film must be removed and wound up and then disposed of.
- the object of the present invention is to provide a method which comprises fewer work steps and can be implemented with less work, so that the manufacturing method for producing a storage part can be operated more cost-effectively.
- FIG. 1 is a schematic, partially sectioned device for producing a storage part using the in-mold method without a carrier film
- Fig. 2 is a plan view of a tape for the
- Anti-slip covering with a storage part to be molded shown in dashed lines below, 3 shows a perspective view of a plastic tray produced by the method according to the invention after the connecting sections have been severed,
- Fig. 4 shows a device for producing a
- Fig. 5 is a view of a storage device with a band that has recesses for an injection opening.
- Fig. 1 denotes an injection molding machine. It has an injection molding press 2, to which a mold half 3.1 of an injection mold 3 is connected. The side 3.3 of the mold half 3.1 facing the mold cavity 3.2 is profiled in accordance with the shape of the underside 4.1 of a storage part 4 to be produced, here a tray.
- At least one sprue 3.1.1 is provided in the mold half 3.1, through which a material forming a storage part 4 can be injected into the mold cavity 3.2 when the injection mold 3 is closed, via the injection molding press 2.
- the material for the storage part 4 consists of a thermoplastic or thermoset, in particular of or based on acrylic-butadiene-styrene (ABS), styrene-acrylic-nitrile (SAN), polypropylene (PP) or polycarbonate (PC).
- ABS acrylic-butadiene-styrene
- SAN styrene-acrylic-nitrile
- PP polypropylene
- PC polycarbonate
- the second mold half 3.5 of the injection mold 3 can be moved against the first mold half 3.1 via a drive 3.8 of the injection molding machine 1. This has a circumferential groove 3.6 corresponding to the bead 3.4 and a plateau 3.7 delimited by it.
- a tape 6 is wound on a storage device 5, for example a roll.
- a storage device 5 for example a roll.
- This consists of a material that has anti-slip properties.
- the coefficient of friction is expediently at least about 0.1.
- the band 6 is pulled off the supply device 5 and pulled through the mold cavity 3.2 until a defined section 6.1 with respect to the injection mold 3 is correctly positioned in the mold cavity 3.2.
- the band 6 consists of a thermoplastic elastomer which is advantageously thermoformable. Suitable materials are those made of or based on polyurethane, polyester or the like.
- the band 6 or at least the respective section 6.1 can be partially printed with a color on the side 6.2 facing the injection opening 3.1.2, for example in the form of geometric shapes, letters, symbols or the like.
- a transparent or translucent band 6 also or only that opposite the injection opening 3.1.2 lying side 6.3 of the band 6 may be wholly or partially printed with at least one color.
- a colored band 6 can also be used and this if necessary. also be printed.
- the section 6.1 After the section 6.1 has been drawn into the mold cavity 3.2 of the open injection mold 3, the latter is closed and the material for the molding or storage part 4 is injected.
- the material for the molded or storage part 4 is permanently connected to the material of the band 6 in a positive and non-positive manner to form a uniform body.
- the injection mold 3 is opened, the molded storage part 4 is removed from the mold and then pulled out of the mold cavity 3.2, downward in the drawing.
- the tape 6 still adhering is removed from the storage device 5.
- a further section 6.1 has been drawn into the mold cavity 3.2, so that the molding process for producing the next shelf 4 can begin. In this way, storage parts 4 are continuously manufactured.
- the individual storage parts 4 are separated from one another by separating the connecting sections 6.4 remaining between two shaped storage parts 4.
- FIG. 2 shows a view of the band 6 within the mold cavity 3.2 and FIG. 3 shows a storage part 4 produced by the method according to the invention in the form of a tablet with a top surface 4.2
- Anti-slip covering 7 in the form of the injected and molded in the injection mold 3 band section 6.1, which also covers the edge bead 4.3 and the edge flange 4.4.
- a storage part 4 can be provided on both sides with an anti-slip covering 6 or 9. This is preferably done in such a way that, according to FIG. 4, a further storage device 8 is provided with a band 9 made of a material with anti-slip properties and this is drawn in between the band 6 and the mold half 3.5 not provided with the sprue 3.1.1.
- the tape 9 can also be completely or partially printed with color on one or both sides.
- the mold halves 3.1 and 3.5 have vacuum channels, not shown in the drawing, which are connected to a vacuum system, for example a vacuum system. If the corresponding sections 6.1 and 9.1 of the belts 6 and 9 have been drawn into the mold cavity 3.2, vacuum is applied to the vacuum channels when or after the injection mold 3 is closed, as a result of which one belt 6 is applied to the inner surface of the mold half 3.1 and the other Band 9 sucked onto the inner surface of the other mold half 3.5. Subsequently, the material for the storage part 4 to be molded is injected into the space formed between the belts 6 and 9 through a recess 6.5 (see FIG. 5) provided in the region 10 of the injection opening 3.1.2 of the sprue 3.1.1.
- a vacuum system for example a vacuum system.
- the further process sequence then follows, as already described with reference to FIG. 1.
- the result is a part 4, which is provided on both sides with an anti-slip covering.
- a storage part 4 in particular a tray, cannot therefore slide away on a table or other surface, and no objects placed on its surface can slip due to vibrations or inclinations of the storage part 4, in particular trays, or as a result of centrifugal force or the like.
- cutouts 6.5 two strips 6 ′ and 6 ′′ located next to one another at a distance 11, indicated by dashed lines in FIG. 5, can be provided in this double-sided method.
- the resulting free slot runs through the injection opening 3.1.2, so that the material for the storage part 4 to be molded can be injected through this free slot.
- the width 6.6 of the band 6 (FIG. 2) or the bands 6 and 9 is dimensioned in the case of storage parts 4 with an edge bead 4.3 in such a way that it is smaller than the clear width 4.5 between mutually opposite sections of the edge bead 4.3.
- section 6.1 or section 9.1 can be carried out via a sensor and control device 12. Likewise, the removal of the part 4 can be automatically effected . lie.
- Any support or storage parts can be considered as storage parts 4, for example dashboard shelves, non-slip keyboards, toiletries in the handle area or the like.
