They have a rigid skeleton, and the main chain of the macromolecule contains a large number of aromatic rings and heterocyclic rings. Some conjugated double bonds are arranged in an orderly manner in a trapezoidal or semi-trapezoidal structure. The molecules have good regularity, and show the characteristics of high rigidity and high melting point (or high viscosity flow temperature). Even at high temperatures, their molecular chains can still maintain a relatively fixed arrangement.

[0003] The existing patent (publication number: CN217196577U) discloses a hot press for producing special plastics. The hot press for producing special plastics described in the utility model is characterized in that it includes a load-bearing platform, an output bucket, a first telescopic column, a second telescopic column, and a heating frame. The four corners of the lower end of the load-bearing platform are all provided with load-bearing blocks, the upper end of the front side of the load-bearing platform is provided with two supporting columns, the upper end of the rear side of the load-bearing platform is provided with a supporting plate, the upper end of the support plate is provided with a load-bearing plate, the upper end of one side of the load-bearing plate is provided with the output bucket, the lower end of the output bucket is provided with the first telescopic column, the telescopic end of the first telescopic column is provided with a closing plate, the upper end of the other side of the load-bearing plate is evenly provided with four connecting shafts, the upper end of the connecting shaft is provided with a connecting plate, and the lower end of the connecting plate is provided with the second telescopic column; the structure of the device is simple and easy to operate, and if it is a newcomer who has been exposed to the device, he can quickly get started, and most of the devices in the device are easy to disassemble, and if the device fails, it is also convenient to disassemble and repair.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The models required for extrusion molding of different materials are not consistent, and the extrusion mold needs to be replaced to meet the requirements of different shapes and appearances; 2. When the plastic is hot-pressed, the plastic melts due to heating, and the pressure extrusion causes the plastic to spread around during hot pressing, forming an irregular shape, and it is easy to hang on the extrusion plate, causing material loss; 3. After hot pressing molding, it is usually taken out manually. Because it has just been heated, it is easy to cause burns to personnel. If it is waiting for natural cooling, the production output will be reduced. Utility Model Content
