Problems solved by technology

[0003] However, when the existing residence mold is demolded after the injection molding is completed, the thimble is often used to withstand the movement of the mold for demoulding. Since the mold is glued to the inner wall of the injection cavity to a greater extent after cooling in the injection cavity, it takes a large amount of time to withstand it. The thrust can eject the mold and realize demoulding, which makes the thimble easily cause damage to the injection molded mold, thereby affecting the quality of the injection mold. However, some existing inflatable demoulding structures need to be equipped with air injection holes, which are easy to Affect the overall molding effect of the mold, and then affect the quality of the injection mold

Abstract

The invention relates to the field of injection molding equipment, and discloses a high-precision injection mold. The high-precision injection mold comprises a lower die holder plate, an isolation plate, a lower die core fixing plate, an upper die core fixing plate and an upper die holder plate, wherein the isolation plate is fixedly mounted at the top of the lower die holder plate, the lower moldcore fixing plate is fixedly mounted at the top of the isolation plate, and the upper mold core fixing plate is fixedly mounted at the bottom of the upper die holder plate. According to the high-precision injection mold, through the structural design of a first sliding groove and a second sliding groove which communicate with each other in the lower die core fixing plate and the upper die core fixing plate, during demolding, water is injected into the first sliding groove for pressurization, so that a first piston plate reaches a through hole, the water pressure in the second sliding groove is increased, and a second piston plate drives an inserting rod to move upwards; and the injected water directly acts on the mold adhered to the upper die core fixing plate through a packing block, sothat the mold is separated from the upper die core fixing plate, and the problem that the quality of the mold is influenced due to the fact that an ejector pin damages the surface of the mold is avoided.

Description

technical field [0001] The invention relates to the field of injection molding equipment, in particular to a high-precision injection mold. Background technique [0002] It is a tool for producing plastic products, and it is also a tool for endowing plastic products with special structures and precise dimensions. It is commonly used in the production of irregular products. By injecting molten raw materials into the sealed mold, the molten material fills the mold, thereby cooling and forming. Obtain the required molds, and its products are widely used in aviation, aerospace, electronics, machinery, ships and automobiles and other fields. [0003] However, when the existing residence mold is demolded after the injection molding is completed, the thimble is often used to withstand the movement of the mold for demoulding. Since the mold is glued to the inner wall of the injection cavity to a greater extent after cooling in the injection cavity, it takes a large amount of time to...
