[0032] Specifically, the demoulding assembly includes a motor 11, the bottom of which is installed on the inner wall of the bottom end of the L-shaped supporting plate 10, and the driving end of the motor 11 is fixedly connected to a linkage plate 12, and the inner wall of the bottom end of the linkage plate 12 is rotatably connected to a fixed rod 13, and the front side of the outer wall of the fixed rod 13 is rotatably connected to a slider 18, and the outer wall of the slider 18 is slidably connected to an empty slot frame 17, and the front end of the empty slot frame 17 is fixedly connected to a slide bar 5, and the outer wall of the slide bar 5 is slidably connected to the inner wall of the bottom end of the lower mold 8, and the top of the slide bar 5 is fixedly connected to the bottom end of the demoulding push plate 14. Starting the motor 11 drives the linkage plate 12 to rotate the fixed rod 13, so that the slider 18 slides left and right in the empty slot frame 17. When the fixed rod 13 rotates to the top, the empty slot frame 17 will be driven to move up through the slider 18, and then the slide bar 5 will slide upward in the lower mold 8, thereby pushing the demoulding push plate 14 to push the injected product out of the lower mold 8, which is convenient for demoulding, improves work efficiency, and speeds up production progress.
