Abstract

The invention relates to the technical field of molds, in particular to a stable injection mold for an automobile bumper. The stable injection mold comprises a rack, a lifting assembly, a rotating assembly, a mold pressing assembly and a buffering assembly. The lifting assembly, the rotating assembly and the buffering assembly are arranged on the rack. The mold pressing assembly is arranged on the rotating assembly. The buffering assembly is located below the mold pressing assembly. Ventilation valves are arranged on an upper mold body and a lower mold body. According to the stable injection mold, the lifting assembly and the rotating assembly are arranged, and a lifting base is used for driving a mold plate to ascend and descend on the rack; a movable base is used for driving the mold plate to rotate on a rotating disc, and therefore the motion form of the mold in the injection molding process is increased, the mold is driven to rotate, the uniformity degree of materials in the mold can be improved, and then the production quality of the materials is improved; and the mold pressing assembly is arranged, the mold pressing stability of the upper mold body and the lower mold body on the mold plate is improved, and the upper mold body and the lower mold body can synchronously rotate with the rotating disc in the press fit state.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a stable injection mold for automobile bumpers. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die-casting method; in order to improve production efficiency, automobile bumpers are mostly produced by injection molds. [0003] Existing injection molds have a single movement mode during work, and the air contained in the material inside the mold is difficult to discharge, resulting in a low degree of uniformity of the material in the mold, and the standard of the bumper produced is poor, which is inconvenient and widely popularized. Contents of the invention [0004] In order to solve the technical problems existing in the background technology, the present invention ...
