Abstract
The utility model relates to a low-pressure injection mold with a skin material groove crease-proof structure and belongs to a structure of a low-pressure injection forming mold. According to the low-pressure injection mold with the skin material groove crease-proof structure, the upper end of a skin rod passes through a lower die assembly; a spring mechanism is arranged at a position of the lower end of the skin rod, located in an ejection plate; and a limiting ball plunger is arranged in a movable die bottom plate. As the coordination effect of a spring and the ball plunger is adopted for the skin material groove crease-proof structure, the motion mode of the skin rod is skillfully regulated, the occurrence of skin creases is greatly reduced, the qualified rate of a product is effectively improved, the production cost is saved, a skin integrated process can be widely suitable for various product shapes, and the application range of the low-pressure injection mold is broadened.
Description
Technical field
The utility model relates to a kind of low pressure injection mould with the wrinkle resistant structure of surface layer material groove, belongs to the low-pressure injection mould structure.
Background technology
The mould of the in the past skin-integrated moulding of low-pressure injection molding is multiplex comparatively mild in producing, little goods rise and fall, because the car door backplate of this exploitation requires to have in appearance epidermis and the two kinds of effects of fitting to have both, and the long and narrow groove between two kinds of effects has just become this time difficult point of design, do not adopt before this scheme, the one-sided stretching of epidermis in mould is so that epidermis large-area fold occurs in groove one side, seriously influence products appearance, increased percent defective.
Summary of the invention
The utility model provides a kind of low pressure injection mould with the wrinkle resistant structure of surface layer material groove, and this low pressure injection mould should adopt the wrinkle resistant structure of surface layer material groove, and is simple in structure, applicable different article shape that can be general, guarantee the quality of goods finished product, enhance productivity, the reduction production cost.
The technical solution adopted in the utility model is: a kind of low pressure injection mould with the wrinkle resistant structure of surface layer material groove, it adopts an epidermis bar to pass lower membrane module, described epidermis bar stretches in liftout plate and the moving clamping plate, the bottom of liftout plate is fixedly connected with a spring fixed block, in liftout plate and spring fixed block, be provided with a spring housing, Rectangular Spring is arranged in the described spring housing of annular protrusion bottom of epidermis bar, be fixedly connected with a fixed head in the moving clamping plate, the position of stretching into fixed head at the epidermis bar is provided with a spacing bulb plunger.
Described lower membrane module adopts moving platen, dynamic model backing plate, hot flow path pad post, hot runner flow distribution plate to be connected in turn.
The top that described epidermis bar is arranged in the annular protrusion of spring housing is provided with toroidal cavity.
Be provided with successively spring, spring pad and steel ball in the described bulb plunger, steel ball withstands on the chute that is arranged in epidermis bar lower end.
Above-mentioned technical scheme is by the compression elasticity of spring, make the groove of epidermis pole pair goods realize certain replenishing, with the fin section of cover half epidermis is produced chucking power, make it keep good spreading, avoid the generation of partial drape, moreover, the position-limiting action of bulb plunger is when depanning, guaranteed preferably the synchronism of epidermis bar and other ejector member, this scheme has solved the epidermal fold situation in the skin-integrated moulding of low-pressure injection molding well, improve production efficiency, guaranteed the quality of goods finished products, reduced production cost.
The beneficial effects of the utility model are: this low pressure injection mould with the wrinkle resistant structure of surface layer material groove adopts the upper end of epidermis bar to pass lower membrane module, the position that is arranged in liftout plate in the lower end of epidermis bar is provided with spring mechanism, is provided with spacing bulb plunger in moving clamping plate.The wrinkle resistant structure of this surface layer material groove is utilized the coordinative role of spring and bulb plunger, adjusted dexterously the manner of execution of epidermis bar, greatly alleviated the generation of epidermal fold, effectively raise the qualification rate of product, saved production cost, also so that skin-integrated moulding process can be widely applicable for various article shape, enlarged the range of application of low pressure injection mould.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a kind of structure front view with low pressure injection mould of the wrinkle resistant structure of surface layer material groove.
Fig. 2 is a kind of structure side view with low pressure injection mould of the wrinkle resistant structure of surface layer material groove.
Fig. 3 is the A enlarged drawing of Fig. 1.
Fig. 4 is the structure chart of bulb plunger.
Among the figure: 1, epidermis bar, 1a, annular protrusion, 1b, toroidal cavity, 2, Rectangular Spring, 3, fixed head, 4, the spring fixed block, 5, bulb plunger, 5a, spring, 5b, spring pad, 5c, steel ball, 6, liftout plate, 7, moving clamping plate, 8, moving platen, 9. dynamic model backing plate, 10, hot runner flow distribution plate, 11, hot flow path pad post, 12, surface layer material, 13, resin bed.
The specific embodiment
The below is further described embodiment with reference to the accompanying drawings.
Fig. 1,2 shows the structure side view of the low pressure injection mould with the wrinkle resistant structure of surface layer material groove.Among the figure, this have the wrinkle resistant structure of surface layer material groove and adopt an epidermis bar 1 to pass lower membrane module, and lower membrane module adopts moving platen 8, dynamic model backing plate 9, hot flow path pad post 11, hot runner flow distribution plate 10 to be connected in turn.
The course of work of technique scheme is as follows, before the injecting products, eject first liftout plate 6, with ejecting action, the compression stress of spring 2 increases, and when surpassing the bed knife of bulb plunger 5, epidermis bar 1 can be shaken off the position-limiting action of bulb plunger 5 and push up on the limiting stand, epidermis bar 1 exceeds common push rod certain distance, roughly is equivalent to the degree of depth of groove; At this moment, manipulator is placed into surface layer material 13 on the dynamic model body of mould, the pre-punching at surface layer material 13 two ends drops on the locating dowel, in the matched moulds process, the injection machine injecting glue, resin bed 12 heat are melted to the foam films at surface layer material 13 back sides, form the front material base (as shown in Figure 3) of die mould, epidermis bar 1 and the cover half fin that falls form a kind of surface layer material tensile force of equity, have processed well the fold degree of epidermis.
