Multi-station macromolecular vacuum hot press

Abstract

The invention relates to a multi-station macromolecular vacuum hot press. The device comprises a supporting bottom shell, an inner frame is installed on the supporting bottom shell, box plates are arranged on the top, the back, the left side and the right side of the inner frame, and a box door is hinged to the front portion of the inner frame; a plurality of hydraulic cylinders are installed on the box plate located at the top, and a hot pressing device is installed in the inner frame; the hot pressing device comprises a fixed platform and a lifting platform, the lower end of a piston rod ofeach hydraulic cylinder is fixedly connected with the lifting platform, and a plurality of hot pressing plate assemblies are arranged between the lifting platform and the fixed platform; each hot pressing plate assembly comprises a hot pressing plate body, a plurality of heating channels are formed in the each hot pressing plate body, electric heating bars are installed in the heating channels, aplurality of temperature measuring channels are further formed in the hot pressing plate bodies, and temperature sensors are installed in the temperature measuring channels; and the hot pressing device further comprises telescopic supporting arm assemblies located on the left side and the right side correspondingly, and a hydraulic station and an air extractor are further included. The multi-station macromolecular vacuum hot press is reasonable in structural design, high in machining efficiency and good in machining environment consistency of multiple sets of materials.

Description

technical field [0001] The invention belongs to the technical field of hot press equipment, and in particular relates to a multi-station polymer vacuum hot press. Background technique [0002] Polymer materials, also known as polymer materials, are materials composed of polymer compounds as the matrix and other additives (auxiliary agents). They are widely used in daily life and industrial products. Polymer material molding processing usually refers to the process of melting or deforming polymer compounds in solid state (powder or granular), pasty or solution state, forming the shaken shape through a mold and maintaining the obtained shape, and finally obtaining the product. process. Polymer materials are divided into thermoplastic materials and thermosetting materials. Thermoplastic materials refer to plastics with heating softening and cooling hardening properties (such as ABS, PP, POM, PC, PS, PVC, PA, PMMA, etc.), which can be recycled. It has the characteristics of pl...

AI Technical Summary

Problems solved by technology

[0004] The vacuum hot press with the above structure has the following defects: only one group of materials can be hot pressed at a time, and batch hot pressing processing cannot be realized

Considering that the processing conditions (mainly temperature) of each group of materials need to be kept as consistent as possible during a single processing, very strict requirements are put forward for the structural design of the hot press, which leads to the development and research of the multi-station hot press work stalled
