[0023] In this embodiment: when the car inner door panel needs to be injection molded, the drive motor 5 works, and the output end of the drive motor 5 rotates to drive the demoulding rod 408 to move downward through mechanical rotation. When the bottom end of the upper mold 7 is in contact with the top end of the lower mold 2, the demoulding rod 408 is completely moved to the inside of the lower mold 2, and then the material to be injected is injected into the injection groove formed by the lower mold 2 and the upper mold 7. When the car inner door panel is injection-molded, the output end of the drive motor 5 rotates in the opposite direction and drives the upper mold 7 to move upward through mechanical transmission. The upper mold 7 moves at the same time. At the same time, the demoulding rod 408 is driven to move upward by mechanical transmission, and the upper mold 7 is separated from the lower mold 2.

[0024] Working principle: When it is necessary to perform injection molding on the inner door panel of the automobile, the driving motor 5 works, and the output end of the driving motor 5 rotates to drive the threaded column 6 to rotate, and the threaded column 6 rotates to drive the upper mold 7 to move downward, and the upper mold 7 moves downward to drive the moving block 401 to move downward, and the movement of the moving block 401 drives the moving rod 402 to move, and the movement of the moving rod 402 drives the cylindrical boss at the bottom end of the moving rod 402 to move, and the movement of the cylindrical boss drives the ball to move, and the ball moves in the spiral groove on the inner wall of the rotating rod 403, and then drives the spiral groove to rotate, and the rotation of the spiral groove drives the rotating rod 403 to rotate, and the rotation of the rotating rod 403 drives the first synchronous wheel 404 to rotate, and the rotation of the first synchronous wheel 404 drives the synchronous belt 405 to rotate, and the rotation of the synchronous belt 405 drives the second synchronous wheel 406 to rotate, and the rotation of the second synchronous wheel 406 drives the threaded rod 407 to rotate, and the rotation of the threaded rod 407 drives the demoulding rod 408 to move downward. When the bottom end of the mold 7 fits with the top end of the lower mold 2, the demolding rod 408 moves completely to the inside of the lower mold 2, and then the material to be injected is injected into the injection groove formed by the lower mold 2 and the upper mold 7. When the injection molding of the automobile inner door panel is completed, the output end of the driving motor 5 rotates in the opposite direction and drives the upper mold 7 to move upward through mechanical transmission. The upper mold 7 moves and at the same time drives the demolding rod 408 to move upward through mechanical transmission. At the same time, the upper mold 7 is separated from the lower mold 2, the demolding rod 408 squeezes the injection-molded automobile inner door panel and moves upward. The automobile inner door panel moves and separates from the lower mold 2. After that, the staff can pick up the molded automobile inner door panel.
