Abstract

The invention relates to injection molding equipment for plug injection molding, and relates to the field of injection molding equipment. The injection molding equipment comprises a terminal clamping base, a machine base and an injection molding device. The injection molding device comprises an upper mold, a lower mold, a driving mechanism and a material injection mechanism, wherein the lower mold is fixedly installed on a rack, the driving mechanism is fixedly installed on the rack and connected with the upper mold to drive the upper mold to ascend and descend, the upper mold is provided with an upper receding cavity and an upper cavity which are communicated with each other, the lower mold is provided with a lower receding cavity and a lower cavity, the upper cavity and the lower cavity are spliced to form an injection molding cavity, the upper receding cavity and the lower receding cavity are spliced to form a placing cavity for placing the terminal clamping base, the terminal clamping base is provided with a jack for inserting a plug terminal, and the jack penetrates through the terminal clamping base. The injection molding equipment has the effect of reducing the skew probability of the plug terminal.

Description

technical field [0001] The present application relates to the field of injection molding equipment, in particular to an injection molding equipment for plug injection molding. Background technique [0002] Wire plugs are very common and necessary electrical devices in life and production. After the wires are connected in production, the wire plugs need to be injected with plastic to wrap and hide the connecting wires, which is safer and more convenient to use. [0003] The existing plug injection molding process is that the operator puts the terminal in the lower cavity of the lower mold, and then the upper mold is lowered to fit the lower mold, and the upper cavity of the upper mold is connected with the lower cavity of the lower mold. Flatten to form injection cavity. The injection molding mechanism injects molten plastic into the injection cavity to complete injection molding. [0004] With regard to the above-mentioned related technologies, the inventor believes that t...
