AI Technical Summary

Technical Problem

In the use of existing molding equipment, PS recycled plastic sheets tend to get stuck in the recess of the lower mold, making them difficult to remove, especially when the heat increases after extrusion, making them even more difficult to remove manually.

Method used

The upper plate is driven by a hydraulic rod to move the lower mold upward. Combined with a spring mechanism, the lower mold moves upward through the transmission of elastic potential energy. With the help of a sliding rod and a clamping plate structure, the PS recycled plastic sheet can be stably removed. The mold position is fixed by a screw and a clamping hole structure to accommodate the production of sheets of different thicknesses.

Benefits of technology

It enables stable extraction of PS recycled plastic sheets, avoids mold deformation and damage, improves the structural stability and linkage of the equipment, and can produce sheets of different thicknesses.

Abstract

This utility model provides a shaping device for PS recycled plastic sheets, belonging to the technical field of shaping devices. It includes two side frames, with a platform fixedly connected between one side of each side frame. Hydraulic rods are fixedly connected inside each side frame, and a top plate is fixedly connected between the top ends of the four hydraulic rods. In this utility model, during the upward movement of the fixed plate using a first spring, the elastic potential energy released by the first spring gives the clamping plate an upward force. This force is then transmitted to the lower mold, allowing the lower mold to buffer the force on the fixed plate as it passes through the sliding tube, preventing sudden deformation and damage to the clamping plate, bottom plate, and lower mold. Simultaneously, the first spring pulls the clamping plate, bottom plate, and lower mold downwards, stabilizing the bottom plate at the top of the fixed tube, thereby stabilizing the lower mold inside the square tube and increasing the structural stability of the lower mold.
