Description
Technical field
The utility model relates to injection-compression molding technology, is specifically related to a kind of handle type injection mould.
Background technology
Thermosetting plastics refers to and is being heated or can solidifying or have the plastics of insoluble (melting) characteristic under other conditions, as phenoplasts, epoxy plastics etc.Injection-compression molding, after thermosetting plastics being placed on the indoor plasticizing of mold addition, by pressure effect, clamp-oning in closed mold cavity at a high speed, after curing molding, obtain the forming method of plastic products by running gate system by it.Existing compression moulding die, often can one-shot forming more than one piece goods, namely arrange multiple die cavity, are fed in raw material by same sprue.Reinforced chamber is generally arranged on the medium position of upper cavity die or lower cavity die; namely sprue is just in time positioned at middle part; and communicate with each die cavity; be designed with the both sides that the plastics being beneficial to melting flow to die cavity in runner like this; even if but this design, still there is certain problem: because the flowing of the plastics of each several part melting is uneven, therefore usually cause the plastics flowing to side more; opposite side is less, and each plastic wall thickness after shaping is inconsistent.
Utility model content
The utility model is intended to provide a kind of handle type injection mould, to make the plastics flow velocity of the melting flowing to die cavity both sides even, guarantee shaping after product wall thickness consistent.
Handle type injection mould in this programme, comprise cope match-plate pattern, cope match-plate pattern is provided with several electrothermal tubes, cope match-plate pattern bottom is provided with upper impression plate and metal inserted piece side by side, the middle part of upper impression plate is provided with patrix mold insert down, relative with metal inserted piece with upper impression plate is provided with lower impressions plate, the first die cavity is formed between upper impression plate and lower impressions plate, the second die cavity is formed between metal inserted piece and lower impressions plate, sprue is formed between patrix mold insert and lower impressions plate, described sprue communicates with the first die cavity and the second die cavity respectively, lower bolster and lower impressions plate are respectively equipped with the push rod for inloading part that can extend in the first die cavity and the second die cavity, lower impressions plate is positioned at lower bolster top, lower impressions plate has vertical via hole, be equipped with in via hole can along via hole vertical motion and with the lower reinforced plunger of via seal, the longitudinal section of sprue is V-shaped, spreader is down provided with at the middle part of patrix mold insert, the conehead of spreader is positioned at sprue.
The utility model has the advantage of: 1. the longitudinal section of sprue is V-shaped, strict symmetric design, the uniformity of the rate of flow of fluid flowed in two die cavities can be ensured; 2. in the middle part of patrix mold insert, spreader has been installed, and the conehead of spreader extend in sprue, plastics like this through the melting of sprue inflow can flow down in the space of inflow two die cavities of even equivalent in dividing of spreader, all fully can fill by true two die cavities, guarantee that the plastic wall thickness processed is consistent.
Further, lower bolster is arranged on a support plate, and support plate is bearing on two relative the first rest pads by two asbestos boards, and lower bolster and support plate are equipped with several electrothermal tubes.Support plate and lower bolster all arrange electrothermal tube, ensures the forming temperature of mold integral, and support plate is bearing on two relative the first rest pads by two asbestos boards, asbestos board plays heat insulation effect, prevents the heat of support plate from conducting downwards.
Further, the lower end of push rod is fixed on ejector pin retaining plate, and ejector pin retaining plate is positioned at two the first rest pads and can slides along the medial surface of two the first rest pads.When ejector pin retaining plate moves, the side of two the first rest pads has guide effect to its motion.
Further, have pilot hole at the middle part of ejector pin retaining plate, described lower reinforced plunger is through described pilot hole.When lower reinforced plunger action, pilot hole plays the effect of guiding to its vertical motion.
