Novel plastic injection mold

Abstract

The invention discloses a novel plastic injection mold which comprises an upper mold and a lower mold, wherein a plastic injection mold cavity is formed when the two molds are closed; a material filling hole is formed in the top of the upper mold; the upper mold and the lower mold are connected by screws to achieve positioning and locking; the screws are connected to the left side and the right side of the outside of the plastic injection mold cavity respectively; light holes are formed in the upper mold; threaded holes are formed in the upper surface of the lower mold; and the locking force of the screws for connection are adjustable. According to the novel plastic injection mold, the structure design is reasonable; the upper mold and the lower mold are connected by the screws, the connecting mode is simple and convenient to operate, the connecting performance is stable; meanwhile, marks and scales are formed in the heads and the peripheral surfaces of the screws, so that the locking force is conveniently determined, the two ends of the mold are uniformly stressed in theory, the position of the jointing surface of the mold is more accurate and stable, and the appearance performance and the surface quality of a finished plastic injection product are guaranteed.

Description

technical field [0001] The invention relates to an injection mold, in particular to a novel injection mold capable of effectively controlling the locking force of the mold, and belongs to the technical field of molds. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form the gating system and the mold Cavity, when the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product. There are many types of injection molds, which can be divided into thermosetting plastic molds and thermopl...

AI Technical Summary

Problems solved by technology

However, the locking force of the bolt connection on the left and right sides of the mold cannot be precisely controlled, and it is easy to have an unbalanced locking force, which affects the stability of the mold joint surface, causing deformation or dimensional deviation of the injection molded product; at the same time, the injection mold The frequency of disassembly and assembly is high, and the performance of bolt connection is not as good as that of screw connection, which has a certain impact on the efficiency of injection molding production process
