[0014] By adopting the above technical solution, the small hinge, short hinge, and long hinge work together for the operation of the lower mold.

[0015] Optionally, fixing blocks are installed at the four corners of the upper mold. The fixing blocks are installed on the outside of the adjusting rod, and the adjusting rod is fixedly installed on the upper part of the Green Column. Multiple locking positions are provided on the outside of the adjusting rod.

[0016] By adopting the above technical solution, a fixing block is installed on the outside of the adjusting rod to achieve height adjustment of the upper mold.

[0017] Beneficial effects: This utility model integrates the power unit into the lower mold, reducing the weight of the tail plate and making the overall volume more space-saving. The servo motor drives the lead screw transmission, and the cross movable plate ensures the accuracy of the up and down movement through the support of the guide column and the tube position. The up and down movement of the cross movable plate drives the small hinge, short hinge, and long hinge cycloidal movement to perform the function of opening and closing the mold. It covers a wide range of positions and can be applied to 20-200T electric vertical injection molding machines. Attached Figure Description

[0021] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, such as... Figures 1 to 2The device includes a tail plate 1, a guide column 3 fixedly installed in the middle of the tail plate 1, a support guide column 4 slidably installed on the outside of the guide column 3, a lead screw 9 installed in the middle of the support guide column 4, a lower mold 6 installed on the top of the lead screw 9, and an upper mold 8 installed on the upper part of the lower mold 6. This utility model integrates the power part into the lower mold 6, reducing the weight of the tail plate 1 and making the whole volume more space-saving. The lead screw 9 is driven by a servo motor 5. The cross movable plate 10 ensures the accuracy of the up and down movement through the support of the support guide column 4 and the tube position. The up and down movement of the cross movable plate 10 drives the small hinge 12, short hinge 11, and long hinge 14 to perform cycloidal motion, which plays a major role in opening and closing the mold. It covers a wide range of positions and can be applied to 20-200T electric vertical injection molding machines.

[0022] A servo motor 5 is installed at one end of the bottom of the lower mold 6. The output end of the servo motor 5 is connected to the lead screw 9 through a transmission mechanism. When the servo motor 5 works, it is driven by the transmission mechanism to rotate the lead screw 9.

[0023] Green columns 2 are fixedly installed at both ends of the tail plate 1. A lower mold 6 is slidably installed on the outside of the green columns 2. The lower mold 6 slides on the outside of the green columns 2 for stable movement.

[0024] A cross-shaped movable plate 10 is fixedly installed on the outside of the support guide column 4. The cross-shaped movable plate 10 moves up and down to stabilize the lower mold 6.

[0025] A small hinge 12 is installed on the outer side of the cross movable plate 10. A short hinge 11 is installed at the outer end of the small hinge 12. A long hinge 14 is installed at the lower part of the short hinge 11. The long hinge 14 is installed on the upper part of the tail plate 1.
