Injection mold with function of improving workpiece strength

Abstract

The invention relates to the technical field of injection molding equipment, and discloses an injection mold with the function of improving the workpiece strength. The injection mold comprises a bottom plate, a lower mold body is fixedly connected to the upper surface of the bottom plate, an upper mold body is connected to the upper surface of the lower mold body in a lap-joint mode, a top plate is fixedly connected to the upper surface of the upper mold body, through grooves are formed in the top plate, and fixing rods are movably inserted into the through grooves. According to the injectionmold with the function of improving the workpiece strength, the effect of changing the air pressure in air cavities is achieved in the mode that first blocking plates move through moving rods, and therefore second blocking plates can conveniently move and be fixed; and supporting rods are fixed by the second blocking plates through fixing blocks and fixing plates, the effect of fixing the upper mold body and the lower mold body is achieved, the connecting force effect of the upper mold body and the lower mold body is improved, the condition that the upper mold body and the lower mold body generate cracks due to raw materials is reduced, the raw materials can not be leaked, and the effect of improving the workpiece strength is achieved.

Description

technical field [0001] The invention relates to the technical field of injection mold equipment, in particular to an injection mold with increased workpiece strength. 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. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. The injection mold can be divided into cold runner mold and hot runner mold according to the pouring system; it can be divided into mobile type and fixed type according to the loading and unloading method. [0003] When the commonly used injection molds are filled with fillers, the fillers tend to slightly separate the upper an...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an injection mold with increased strength of the workpiece, which solves the problem that when the workpiece is processed by the injection mold, the upper and lower molds are likely to be separated due to the pressure of the workpiece, resulting in the outflow of raw materials and the loss of the workpiece. lower intensity issues
