Abstract

The invention discloses an injection mold which comprises an upper mold core, a lower mold core, a pressing plate, two shovel machine blocks, a first sliding block, two elastic pieces, an inner mold insert and a second sliding block. The lower mold core is provided with a holding cavity; the pressing plate is fixed into the holding cavity and is provided with a terminal positioning groove; the pressing plate comprises a wide part and a narrow part; two holding spaces are formed on two sides of the narrow part; the first sliding block comprises a middle part and two side parts located on two sides of the middle part; the middle part is located on the lower side of the narrow part; the two side parts are respectively held in the two holding spaces; the two shovel machine blocks are respectively inserted into the two holding spaces and are matched with the corresponding side parts; the shovel machine blocks upwards extend out of the holding spaces; two elastic pieces are respectively abutted against the two side parts; the elastic pieces and the shovel machine blocks are located on two opposite sides of the side parts; the second sliding block and the inner mold insert are abutted against the middle part; and the inner mold insert is located on the lower side of the second sliding block and is abutted against the second sliding block.

Description

technical field [0001] The invention relates to the field of injection molding. Background technique [0002] The connectors in the prior art generally include a plastic body and hardware embedded in the plastic body. The hardware is generally formed by punching a metal plate. The hardware has a protrusion, and the plastic body is generally formed by injection molding. In the injection molding process, the hardware is generally placed in the injection mold and positioned, and the plastic body is formed by injection molding. The hardware is embedded in the plastic body, and the protruding part is located outside the plastic body. Due to the precise positioning of the hardware parts by the injection mold, the protruding part is embedded in the injection mold, and it is difficult to remove the injection molded connector from the injection mold. [0003] In view of this, the present invention proposes a new injection mold. Contents of the invention [0004] Aiming at the def...
