[0037] Specifically, the conversion mechanism 2 is primarily composed of an L-shaped fixed column 201, the rear side of which is tightly coupled to the front middle and lower portion of the sliding plate 3 via a fixed connection. A circular groove plate 205 is fixedly mounted on the top of the L-shaped fixed column 201, and a baffle 1 204 is fixedly mounted on the top of the circular groove plate 205.

[0040] Working principle: When using the injection molding demoulding mechanism proposed in the utility model, a sliding box 14 is fixedly connected to the sliding plate 3, and an electric telescopic rod 218 is fixed to the middle of the front side of the sliding box 14. The electric telescopic rod 218 is started to drive the T-shaped fixed column 23 to move toward the middle, and the T-shaped fixed column 23 drives the clamping column 21 to move toward the middle.

[0041] When encountering different demoulding shapes, first start the electric telescopic rod 1 218 at the same time to drive the connecting column 1 210 to move to the right, and the connecting column 1 210 drives the demoulding box 209 to move to the right, and moves the demoulding box 209 to the end connected to the clamping column 21, and then start the motor 1 203 to drive the gear 1 211 to rotate, the gear 1 211 drives the gear 2 213 to rotate, the gear 2 213 drives the gear 3 212 to rotate, the 212 gear 3 drives the annular connecting plate 217 to rotate, the annular connecting plate 217 drives the circular tube 208 to rotate, the circular tube 208 drives the cylindrical connecting column 216 to rotate, the cylindrical connecting column 216 drives the cylindrical fixed column 215 to rotate, and the cylindrical fixed column 215 drives the demoulding plate 214 to rotate. In this way, the demoulding plate 214 with the same shape as the demoulding box 209 can be rotated to the corresponding position, so that the demoulding box 209 is subjected to more uniform force, thereby ensuring the integrity of the demoulding, improving the production capacity and overall production efficiency, and reducing the production cost.
