Abstract
The invention discloses a plastic mold for driving sliding blocks by a fixed mold push plate and a mold release method using the same. The mold comprises the fixed mold push plate and a movable mold push plate at the same time, and four sides of the mold are designed with a structure that four sliding blocks can be opened on four sides. After injection molding and cooling are finished, the fixed mold push plate drives the four sliding blocks to slide and open so as to finish side core pulling. The plastic mold can be used for manufacturing large plastic products with many interweaving positions, has good use effect, is convenient for mold release of the products, has no defects of straining and damaging the products and the like, and has high yield; the mold has a stable structure and high production efficiency; and the integral appearance of the mold is reduced, the cost of the mold is lowered, the tonnage of an injection molding machine is reduced, and the injection molding cost is lowered.
Description
Technical field
The present invention relates to a kind of injection mold, particularly a kind ofly contain cover half push pedal and dynamic model push pedal simultaneously, and drive the plastic mould that slide block is finished side core-pulling by the cover half push pedal.The invention still further relates to method with this mold releasability.
Background technology
Plastic box is a kind of widely used plastic products, because the reason of plastics rigidity deficiency, plastic box has generally all designed reinforcement, so the Turnover Box mould will be designed to the structure that 4 slide blocks are opened on four sides, so that can take out product.Traditional Turnover Box mould substantially all adopts the structure that 4 slide blocks is located at dynamic model.Do not have push pedal but the shortcoming of this class formation is a dynamic model, adopt conventional thimble to eject because it is little to eject area, when article construction complexity or reinforcement more for a long time, tend to take place product and can not push up or push up white phenomenon.The patent 200520090706.8 that is disclosed " a kind of pintongs side core-pulling plastic injection mould " has been done effective improvement to this, and four slide blocks are located in the dynamic model push pedal, and after slide block sliped off, the dynamic model push pedal drove slide block and moves together, and plastic is ejected.But this kind structure is because slide block is located in the dynamic model push pedal, and after slide block sliped off, its stability was good inadequately, and the dynamic model push pedal drive to need slide block to move together, and the dynamic model push pedal needs enough abundant, so can't be used for the mould of large-sized plastic rubber goods.
As mould slide block is located at cover half, the dynamic model push pedal has not just been influenced by slide block, adopt the technology of mentioning in the disclosed patent 200910164709.4 " the oblique core-pulling device of injection mold cover half " this type of mould can be designed to the structure shown in the figure four, slide block is located at cover half.But work as product is to intert the more large-sized plastic rubber goods in position, and when dynamic model, cover half product Bao Li were big, dynamic model, cover half needed to adopt push pedal simultaneously, and two kinds of above-mentioned prior art schemes just can't realize, so need be improved.
Summary of the invention
In order to solve the problems of the technologies described above, it is succinct to the invention provides a kind of processing technology, contains cover half push pedal and dynamic model push pedal simultaneously, and drives the injection mold that Four-slider is finished side core-pulling by the cover half push pedal.In addition, the present invention also will provide the method for this mold releasability of a kind of usefulness.
