[0036] The utility model provides a support plate 201, a hydraulic cylinder body 202 and a U-shaped plate 203, and has the advantage that after multiple buckles are injection-molded and ejected, the multiple buckles can be pushed out by translation along the injection molding end surface of the lower mold of the injection mold body 1 through the U-shaped plate 203, thereby solving the problem that multiple molded buckles cannot be taken out at one time, which wastes time in the removal process.

[0037] Specifically, the pushing structure 2 also includes a wind hood 204 and a negative pressure fan 207;

[0038] The air hood 204 is connected to the through hole 2031 opened in the horizontal section of the U-shaped plate 203; the negative pressure fan 207 is connected to the top joint of the air hood 204 through the air duct 206; the negative pressure fan 207 is selected and used by the technicians in this field according to the actual situation.

[0039] The utility model has the advantage of sucking away debris on the injection molding surface when multiple buckles are pushed out by arranging the wind cover 204, the wind duct 206 and the negative pressure fan 207.

[0040] Furthermore, a limit strip 205 is fixedly provided at the top joint of the wind hood 204. The limit strip 205 adopts an L-shaped structural design. The intersection of the transverse section and the longitudinal section of the limit strip 205 is arranged in an arc shape.

[0044] Working principle: After the buckle is injection molded in the injection mold body 1, the upper mold of the injection mold body 1 is opened. After multiple buckles are ejected, the hydraulic cylinder body 202 pushes the U-shaped plate 203 to move, and the U-shaped plate 203 moves along the injection end surface of the lower mold of the injection mold body 1 to push out multiple buckles. When multiple buckles are pushed out, the connecting plate 2032 and the brush strip 2033 move together with the U-shaped plate 203, and then the debris on the injection surface of the lower mold of the injection mold body 1 is brushed, and the debris does not adhere; the negative pressure fan 207 generates negative pressure in the air hood 204 and the air duct 206, and along with the U-shaped plate 203, the debris brushed by the brush strip 2033 is sucked away from the air hood 204. After the multiple buckles are completely pushed out, the hydraulic cylinder body 202 drives the U-shaped plate 203 to return to its original position and continue the next injection.
