Background technology
Plastic products be adopt plastics be primary raw material process daily necessities, industrial goods general designation.Relative to metal, stone material, timber, plastic products have the advantages such as cost is low, plasticity is strong.The shaping main employing injection moulding of plastic products, is also named injection mo(u)lding.Injection molding equipment is injector, and injector comprises core on solid plate, solid plate and moving platen, solid plate, forms injection die cavity between core and moving platen.With inserts on some plastic products, therefore, before these plastic product formings, need injection die cavity in pre-set inserts, with make inserts and shaping after plastic products form integrative-structure.But at present, plastic insert often locates instability in injection moulding die cavity, is easily moved, and when solid plate and moving platen matched moulds, easily damages mould.
Summary of the invention
The invention provides a kind of plastic injection mould with inserts, to guarantee the stability of inserts at injection-type intracavitary locations.
This programme is as follows: the plastic injection mould of band inserts, comprise solid plate, solid plate is provided with injecting hole, relative with solid plate position is provided with the moving platen with the vertical free degree, the bottom of moving platen is fixing on the supporting plate, the middle part of moving platen has vertical through hole, core is provided with in through hole, the top of core has cylindrical groove, during matched moulds, moving platen is positioned at the end face of core outer ring and the lower surface gluing, sealing of solid plate, cylindrical groove, core is positioned at the upper surface of cylindrical groove outer ring, injection die cavity is formed between through-hole wall and solid plate lower surface, injecting hole communicates with injection die cavity, the inserts of tubular is provided with in cylindrical groove, this programme also comprises side core and has the inserts seat of shaft-like of the vertical free degree, inserts seat comprises little shaft part and large shaft part, the bottom land of cylindrical groove has pilot hole, the aperture of pilot hole and large shaft part equal diameters, little shaft part stretches in cylindrical groove, inserts is set on little shaft part, large shaft part coordinates with core and gripper shoe sliding sleeve respectively, side core is positioned at the radial direction of inserts, the end of side core is connected in the draw-in groove of inserts cylindrical.
This programme operation principle is as follows: before matched moulds, inserts is placed in the cylindrical groove of core, and be set on the little shaft part of inserts seat, then matched moulds, after matched moulds, by injecting hole to injection molding intracavitary administration molding mass, after a period of time is shaping, side core is exited, under the drive of dynamic structure, moving platen is separated with solid plate, i.e. die sinking, after die sinking, plastic products are stayed on core and moving platen, because the large shaft part of inserts seat coordinates with core and gripper shoe sliding sleeve respectively, therefore, drive inserts seat to move upward by power and eject inserts and plastic products, finally the little shaft part of inserts seat is made to be separated with inserts again.
The present invention, by arranging inserts seat and side core, can guarantee the stability of inserts at injection-type intracavitary locations, can not impact mould itself.
Further, also comprise the support be arranged on bottom gripper shoe, the middle part of support has shoulder hole, and shoulder hole internal fixtion has mount pad, and the bottom of large shaft part is fixed on mount pad, and large shaft part periphery is provided with back-moving spring between mount pad and core.Back-moving spring has reset response to inserts seat.
Further, side core is threaded with moving platen.The outer end of side core is stretched out moving platen and is provided with swing handle in its outer end.Side core is threaded with moving platen, facilitates the fine setting of side core, and swing handle facilitates hand rotation side core.
Further, also comprise the guide pillar of the vertical setting be fixed on gripper shoe and moving platen, solid plate is provided with guide pin bushing, during matched moulds, guide pillar can insert in guide pin bushing.During matched moulds, guide pillar is inserted in guide pin bushing, has guide effect to moving platen, makes the die-closed position of moving platen accurate.
Further, be close in the outer end of side core and moving platen outer surface and be provided with cushion cover, moving platen is provided with screw, and the head of screw compresses described cushion cover.Cushion cover has support guide effect when side core rotates to side core, and screw is for compressing cushion cover.
