Abstract
The invention belongs to the field of automobile interior product machining and manufacturing, in particular to a pressing die. The pressing die comprises an upper die and a lower die, and the profiles of the upper die and the lower die are provided with continuous and mutually matched cutting edges along the cutting lines of the product. When the pressing die is used, because the pressing and the edge cutting of the product are completed once, later machining is avoided and machining procedures are reduced, the production efficiency of the enterprise is increased. Meanwhile, because the continuous cutting edges directly cut off excessive materials while pressing and molding the product, the side lines of the molded product are trim and beautiful, the product does not require polishing procedure after edge cutting, and a threat to the health of workers and the pollution to the environment due to fiber dust produced by polishing are also avoided.
Description
Technical field
The invention belongs to automotive trim product processing and manufacturing field, be specifically related to a kind of pressing mold.
Background technology
In automotive trim product processing and manufacturing field, because the advantage such as having a material intensity difference is little, not easy to crack evenly, in length and breadth, hemp fibre board is used widely.Its profile of the mould of existing moulding hemp fibre board is generally epoxy resin layer; profile sideline along institute's converted products in the profile of patrix or counterdie is provided with the continuous angular protrusions of a circle; corresponding another profile is smooth setting, Plate Welding reinforcing for the back side of profile.When production and processing, first hemp fibre board is put between heating and heated, in hemp fibre board after the thermoplastic of PP composition, from between heating, taking out hemp fibre board puts into mould and the automotive trim cover layer of die opening state and binds by press pressure, upper and lower mould matched moulds moulding hemp fibre board, it is positioned at the continuous angular protrusions of the circle of one on profile cutting line and is also pressed into hemp fibre board simultaneously, thereby closely bind also and on the surface in its moulding sideline, extrude fold vestige (being cutting line) in moulding with surface coating at hemp fibre board, then take out moulding hemp fibre board, enter again trimming polishing operation, with sweep-saw, the cutting line along moulding hemp fibre board cuts, after having cut, obtain having the moulding hemp fibre board in certain profile sideline, use afterwards again the coarse side after angle grinding machine polishing cuts, finally obtain hemp fibre board product.In this process, have the following disadvantages: first, because being generally epoxy resin layer, mould upper and lower mould makes profile, the steel plate solid welding of the profile back side, after the long-time continuous folding mould of upper/lower die, its epoxy resin layer profile tend to and steel plate between occur looseningly even to come off, affect enterprises production efficiency, serious even can cause the generation of production accident; Secondly, in Mould Machining operation, the epoxy resin layer all adopting due to the profile up and down of mould, in long processing and manufacturing, the angular protrusions being positioned in its profile will inevitably produce wearing and tearing, its tip material can wear away the very first time, causes to be difficult to find even in follow-up trimming operation and cannot find the cutting line after compacting, also just cannot better carry out following process; Again, in trimming operation, although be printed on cutting line on the moulding hemp fibre board after compacting, can there is artificial trimming error in staff, cause the hemp fibre board product sideline after trimming uneven when carrying out manual trimming with sweep-saw, affects attractive in appearance; Finally, because fiberboard is the wood-based plate that is interweaved moulding and utilized its intrinsic glueability to make by cellulose fibre, in follow-up polishing operation, unavoidably can produce a large amount of fibre dusts, when staff's health is produced to threat, also produce problem of environmental pollution.
Summary of the invention
The pressing mold that the object of this invention is to provide the high and environmental protection of a kind of production efficiency.
For achieving the above object, the utility model has adopted following technical scheme: a kind of pressing mold, and pressing mold comprises upper die and lower die, the profile of described upper and lower mould is at the be provided with cutting edge that be fitted to each other continuous along product cutting line place.
Beneficial effect of the present invention is: after adopting said structure, first, due to product compacting and trimming and once complete, avoided post-production, reduced manufacturing procedure, improved enterprises production efficiency; Secondly, due to what utilize, be that continuous cutting edge directly excises unnecessary material in press-formed product, the sideline of the product after moulding is neat and attractive in appearance, product does not need the operation of polishing again after trimming, and the fibre dust having produced while also having avoided polishing is to staff's health threat and the pollution to environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of patrix;
Fig. 2 is the structural representation of counterdie;
Fig. 3 is the view before upper and lower mould matched moulds;
Fig. 4 is the view of upper and lower mould while closing on matched moulds;
Fig. 5 is the view after upper and lower mould matched moulds.
The specific embodiment
A pressing mold, described pressing mold comprises patrix 10 and counterdie 20, the profile 11,21 of upper and lower mould 10,20 is at the be provided with cutting edge 111,211 that be fitted to each other continuous along product cutting line place.
Further, for guarantee cutting edge 111,211 smoothly trimming and sword face do not interfere with each other, the matched moulds spacing of cutting edge 111,211 is 10 to 20.
Because upper and lower mould 10,20 is Integral iron casting structure, at the upper and lower mould of processing, within 10,20 o'clock, can select directly by casting means, to make mold, by digital control processing mode, processing its profile 11,21 again can correctly coordinate its upper and lower mould 10,20, when guaranteeing its precision, also solved old-fashioned epoxy resin layer profile often and between the strengthening steel slab at its back side the loosening problem even coming off has occurred, ironcasting is more wear-resistant simultaneously, has increased the service life of mould.
In Fig. 3, Fig. 4 and Fig. 5, be the machining state schematic diagram of hemp fibre board 30 when its machine-shaping.In diagram, the junction round-corner transition of its cutting edge 111,211 1 side edge faces and profile 11,21, if the junction of cutting edge 111,211 1 side edge faces and profile 11,21 is right angle, when upper and lower mould 10,20 folding mould, product trimming chip is easily piled up in its junction, need to often clear up, and affects the operating efficiency of mould, the selected preferred version of the present invention is that radius R is 5mm, another side edge face of cutting edge 111,211 with profile 11,21 straight postponing.
Because its mould 10,20 needing of product and the profile 11,21 thereof of different structure pattern are all different; cutting edge 111,211 patterns in its profile 11,21 are also different; obvious cutting edge of the present invention 111,211 specific implementations are not addressed the restriction of diagramatic way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
