Description
Technical field
The present invention relates to plastic processing technology, be specifically related to a kind of plastic injection mould with scraping wings.
Background technology
Injection moulding is a kind of molding mode that plastics are conventional, injection molding equipment is injector, injector comprises solid plate, be arranged on core on solid plate and moving platen, solid plate, is formed into die cavity between core and moving platen, after plastic shaping, conveniently discharging, injector is provided with pushing structure, and pushing structure is positioned at moving platen side, therefore the pushing-out structure of whole mould is generally also arranged on moving platen side, during die sinking, plastics are normally stayed in the die cavity of moving platen.But in some cases, because the shape of plastic products limits, especially surface of plastic products has the concave surface of indent, after die sinking, plastic products will be stayed on solid plate and core, and current existing pushing-out structure cannot complete the discharging of above-mentioned plastic products smoothly, normally by manually being forced to deviate from by plastic products from solid plate and core, not only efficiency is low, and easily damages product.
Summary of the invention
The invention provides a kind of plastic injection mould with scraping wings, with the smooth discharging after the plastic product forming realizing special shape.
This programme is as follows: with the plastic injection mould of scraping wings, comprise top clamping plate and gripper shoe, plate face on the left of top clamping plate is fixed with core fixing plate, the middle part of core fixing plate has shoulder hole, the bottom of core is fixed in shoulder hole, the cylindrical of core has the concave surface of indent, moving platen is fixed in plate face on the right side of gripper shoe, the first through hole is had in the middle part of moving platen, first through hole comprises the reaming of cylindrical hole and the close core being positioned at gripper shoe side, core mold insert is provided with in cylindrical hole, end face and the core end face of core mold insert offset, core is provided with runner hole, this programme also comprises scraping wings and puller plate, two lateral plates of scraping wings can offset with the plate face of core fixing plate and moving platen respectively and seal, the second through hole is had in the middle part of scraping wings, core, core mold insert, moving platen, injection die cavity is formed between scraping wings and core fixing plate, runner hole communicates with injection die cavity, the inwall of the second through hole extend in injection die cavity, puller plate is arranged on core fixing plate, the side direction of scraping wings and moving platen, puller plate is provided with bar hole along moving platen die sinking direction, scraping wings and moving platen have all been threaded the first screw and the second screw, the bar portion of the first screw and the second screw is all located in bar hole.
This programme operation principle is as follows: during matched moulds, by runner hole, liquid material is injected in injection die cavity, cylindrical due to core has the concave surface of indent, therefore the working of plastics cylindrical after shaping has the concave surface of indent, during die sinking, working of plastics will persist on core, moving platen is thrown off with core fixing plate and scraping wings under the drive of injector dynamic structure, because the second screw fixed with moving platen is arranged in the bar hole of puller plate, when after moving platen motion certain distance, second screw props up the hole wall of bar hole, drive puller plate is moved together, until after the first screw fixed with scraping wings props up another hole wall of bar hole, drive scraping wings moves and to throw off with core fixing plate by puller plate together, inwall due to scraping wings second through hole extend in injection die cavity, therefore promotion working of plastics moves by scraping wings together, depart from core gradually.
The present invention, when moving platen die sinking, can complete the smooth discharging of special shape working of plastics simultaneously.
Further, in order to liquid material Fast Filling injection die cavity, runner hole is the tapered hole that ecto-entad aperture increases gradually.
Further, the left plate face of gripper shoe is evenly equipped with multiple L shape leg.Leg for other anatomical connectivity in injector.
Further, top clamping plate is fixed with guide pillar, guide pillar respectively with core fixing plate, scraping wings, moving platen, gripper shoe and leg empty set.Guide pillar, when moving platen die sinking, has the effect of guiding to moving platen.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
