Problems solved by technology

[0002] In the production process of plastic products such as door frames, it is necessary to extrude the high-temperature melted plastic through a screw extruder, and to shape it through a mold at the outlet. This mold is composed of two layers, one is directly fixed on the screw extruder After the discharge of the machine, the other layer is combined into a complete mold by connecting. However, the existing molds are mostly spliced ​​by bolts and thread grooves. This combination method is not efficient in installation and disassembly. High, and when the product model needs to be replaced and the mold needs to be disassembled, the user needs to contact the mold to remove the bolts. The high temperature accumulated by the plastic passing through the mold will easily damage the user

Abstract

The invention relates to the technical field of plastic molds, and discloses a mold with mold plates convenient to replace for ABS plastic production and an ABS plastic production process. The mold comprises a fixed mold plate and a mounting mold plate, cylindrical grooves are formed in the left side and the right side of the fixed mold plate respectively, pistons A are arranged on the inner walls of the cylindrical grooves in a sleeving mode, sliding grooves are formed in the top faces of the cylindrical grooves, the top surfaces of the pistons A are fixedly connected with connecting plates, the front side surfaces of the connecting plates are fixedly connected with connecting rods, and the connecting rods penetrate through the front side surface of the fixed mold plate and are fixedly connected with placement plates. Through arrangement of the fixed mold plate, the positions of the fixed mold plate and the mounting mold plate are limited in a clamping mode, then the fixed mold plate and the mounting mold plate are assembled and disassembled by filling and extracting hydraulic oil, and compared with a threaded connection mode, the beneficial effect that the assembling and disassembling efficiency is high is achieved, and meanwhile, workers do not need to get close to the fixed mold plate and the mounting mold plate for disassembling, so that the problem that the workers are scalded by high-temperature molds in the dismounting process after shutdown is avoided.
