Full-automatic plate plastic uptake forming equipment based on hot air circulation

Abstract

The full-automatic plate plastic uptake forming equipment comprises a shell, a hydraulic cylinder and a control module, the hydraulic cylinder and the control module are mounted in the middle of the top of the shell, the bottom of the output end of the hydraulic cylinder penetrates through the shell and is connected with a connecting plate, and the bottom of the connecting plate is connected with an upper pressing plate through a bolt; a lower pressure-bearing table is installed on the lower side of an inner cavity of the shell, a heating device is connected to the bottom of the lower pressure-bearing table, a vacuum compressor mounting box, an air purifier mounting box and a circulating box are sequentially installed at the bottom of the heating device from front to back, and a vacuumizing pump is installed in an inner cavity of the vacuum compressor mounting box; and an air purifier is mounted in an inner cavity of the air purifier mounting box. According to the full-automatic plate plastic uptake forming equipment based on hot air circulation, plastic uptake forming of plates can be achieved, meanwhile, control over the flow speed of internal gas is improved, and therefore closure control over heat in the non-machining process is improved.

Description

technical field [0001] The invention belongs to the technical field of sheet metal processing, and in particular relates to a fully automatic sheet plastic suction forming equipment based on hot air circulation. Background technique [0002] Blister forming, also known as vacuum forming, is one of the thermoforming methods for thermoplastics. The sheet or plate material is clamped on the frame of the vacuum forming machine, and after heating and softening, it is adsorbed on the mold by vacuum through the air channel on the edge of the die, and after a short period of cooling, the molded plastic product is obtained, and the plastic product is taken out. After that, it can be used for sale after trimming. In order to improve the circulation control effect of hot air in the existing plastic forming equipment, the heated air is generally stored and stored, and the upper platen is heated, so as to improve the overall thermal cycle utilization rate. In the process, the speed con...

AI Technical Summary

Problems solved by technology

In order to improve the circulation control effect of hot air, the existing blister molding equipment generally adopts the method of storing and storing the heated air, and heating the upper platen, so as to improve the overall thermal cycle utilization rate. During the process, the speed control of the thermal cycle is relatively low. Most of them use the air pump to drive the flow cycle of the hot air. There is no corresponding gradient change module, so the temperature controllability of the hot air is low, and the thermal cycle is uncontrollable. There is a lot of loss, so it needs to be improved
