[0023] Through the positioning sliding block 3 matched with profiling groove 301 and injection slot 302, the injection part terminal 1 pre-buried on mold core 2 can be supported and fixed, the upper end of injection part terminal can be effectively fixed and supported, the deformation of terminal caused by factors such as deformation and shaking in the process of mold closing is avoided, the injection part terminal 1 always presents a relative vertical state in mold core 2, then the injection part terminal 1 can be smoothly closed, then injection part 6 and injection part terminal 1 can quickly complete injection work.

[0024] In this embodiment, in order to facilitate the smooth sliding of the positioning slider 3, a slider fixing seat 4 is also provided, and the positioning slider 3 is detachably installed on one side of the slider fixing seat 4. The side of the slider fixing seat 4 away from the positioning slider 3 is provided with a linkage member, wherein the linkage member includes an inclined guide column 5, and the side of the slider fixing seat 4 away from the positioning slider 3 is provided with a guide inclined groove 402. The inclined guide column 5 is slidably arranged in the guide inclined groove 402. When the inclined guide column 5 moves upwards, the positioning slider 3 is driven by the slider fixing seat 4 to move away from the injection molding part terminal 1. When the inclined guide column 5 moves downwards, the positioning slider 3 is driven by the slider fixing seat 4 to move towards the injection molding part terminal 1.

[0025] Through the above scheme, in use, the inclined guide column 5 is connected with the movable mold base of the vertical injection molding machine. When the movable mold moves downwards, the inclined guide column 5 moves downwards together with the movable mold. The downward moving inclined guide column 5 drives the positioning slider 3 to move towards the injection molding part terminal 1 through the slider fixing seat 4, so that the injection molding part terminal 1 is inserted into the profiling groove 301, and then the injection molding operation is performed. After the injection molding is completed, the movable mold moves upwards, thereby driving the inclined guide column 5 to also move upwards.

The limiting piece is provided with two groups. The two groups of limiting pieces are respectively arranged on the two sides of the guide inclined groove 402. The two groups of limiting pieces each include an assembly groove 403, a baffle 404, a spring 405 and a limiting block 406. The assembly groove 403 is arranged on the side surface of the slider fixing seat 4 and is in communication with the guide inclined groove 402. The limiting block 406 is slidably arranged in the assembly groove 403. The baffle 404 is fixedly installed on the side of the assembly groove 403 away from the guide inclined groove 402 by means of bolts. The spring 405 is arranged in the assembly groove 403. One end of the spring 405 abuts against one side of the baffle 404, and the other end of the spring 405 abuts against one end of the limiting block 406 away from the inclined guide column 5. The two sides of the inclined guide column 5 are each formed with a stop block 501. One end of the limiting block 406 close to the inclined guide column 5 extends out of the assembly groove 403 under the elastic force of the spring 405 and limits the stop block 501. The limiting block 406 and the stop block 501 are in sliding contact.

[0027] In order to facilitate the disassembly and assembly between the positioning slider 3 and the slider fixing seat 4, the positioning slider 3 is fixed on one side of the slider fixing seat 4 by means of a fixing bolt 401. One side of the slider fixing seat 4 is provided with a through hole in communication with the guide inclined groove 402. One side of the positioning slider 3 is provided with a threaded hole. One end of the fixing bolt 401 extends into and penetrates through the through hole and is threadedly fixed in the threaded hole.
