Description

Novel flat vulcanizing machine

Technical Field

The utility model relates to the technical field of high polymer material processing equipment, in particular to a novel flat vulcanizing machine.

Background

The flat vulcanizing machine is one of important equipment for processing high polymer materials, is mainly used for die casting molding processing of materials such as plastics and rubber, and has a core component of an upper part and a lower part which are heatable high-temperature plates, and is closed by relative movement, so that compaction of the materials in a die is realized, however, after the materials are preheated and softened, because a gas part is sealed in a high-temperature melt, the materials are difficult to escape and remove, a large number of bubbles are often caused to remain in the materials in the die casting process, and the continuity and mechanical properties of the finished products are seriously influenced.

Existing press vulcanizers typically use an improved die casting procedure to remove gas. If the material is preheated, the first pressurization is carried out, the mold opening is carried out after the short compaction, the gas removal is promoted by the instant of pressure release, and then the second pressurization is carried out. In practice, however, the material tends to be closed off in the form of bubbles when it is first pressurized. These bubbles are difficult to be defoamed and removed as desired after the mold is opened.

Therefore, how to take effective means to thoroughly remove the gas in the material before compaction, improve the continuity and quality stability of the die-casting forming product, and solve the common problems in the art, and the technical innovation is performed on the basis of the existing press vulcanizer aiming at the above situations.
