The invention relates to the technical field of communication products, and discloses an intelligent vacuum pumping injection mold for communication equipment shells, including a moving mold, the left and right ends of the moving mold are rotatably connected with screws, and the inside of the moving mold is movable. A movable block, a return spring is fixedly installed between the lower end of the movable block and the movable mold. The injection mold for the shell of communication equipment with intelligent vacuum pumping, when the film is closed by the movable mold to the fixed mold, the movable mold drives the movable plate to move to the fixed frame, drives the rotating gear inside the fixed frame to rotate, and the rotating gear drives the moving plate to move, and the rotating gear in the During the movement, the connecting rod drives the sliding rod to slide left and right in the fixed plate. The sliding rod cooperates with the extrusion rod to exert pressure on the airbag. When the airbag is squeezed, the airbag deflates to the outside. The gas in the injection molding cavity is sucked out, thereby realizing the effect of vacuuming the injection molding cavity.
Description
technical field [0001] The invention relates to the technical field of communication products, in particular to an injection mold for an intelligent vacuum pumped housing of communication equipment. Background technique [0002] In the production process of communication products, different types and models of molds are needed to make their protective shells. The injection mold is to inject the injection molding solution into the mold, and then after it cools down, the mold is taken out to take out the molded injection molded parts. This process can be Suitable for mass production and complex shape products. [0003] However, in the injection molding equipment used in the existing plastic production process, after the molten liquid is injected into the injection mold cavity, when the film is joined between the movable mold and the fixed mold, there will be air inside the injection cavity, which will affect the quality of the injection molded parts. Quality, resulting in bub...
