Vulcanizing machine

Abstract

The invention discloses a vulcanizing machine and relates to the technical field of rubber production. According to the technical scheme, the vulcanizing machine is characterized by comprising a machine frame, a mold platform used for holding rubber is arranged on the machine frame, a hydraulic cylinder and pressurizing block are arranged on the upper side of the mold platform, heating devices arearranged both in the pressurizing block and the mold platform, an upper heating cavity is arranged in the pressurizing block, a lower heating cavity is arranged in the mold platform, the upper heating cavity and the lower heating cavity are both filled with heat conducting oil, the heating devices comprise an upper electric heating piece located in the upper heating cavity and a lower electric heating piece located in the lower heating cavity. When the vulcanizing machine is used for vulcanizing rubber, a rubber workpiece is heated evenly, the vulcanization quality of the rubber is good, andthe overall quality of a rubber product is good; the upper electric heating piece and the lower electric heating piece can automatically rotate, so that the temperature evenness degree of the heat conducting oil is further improved; through arrangement of an upper heat preservation board and a lower heat preservation board, heat waste of the heat conducting oil is reduced, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of rubber production and processing, in particular to a vulcanizer. Background technique [0002] During the production and processing of some auto parts, it is necessary to add rubber between multiple steel products, so that the products can meet the technical requirements of elasticity and structural strength. In the prior art, a vulcanizer is usually used to vulcanize the product. Vulcanization is also called cross-linking and curing. Vulcanization refers to the addition of cross-linking aids such as vulcanizing agents and accelerators to the rubber, under certain temperature and pressure conditions. The process of transforming the linear macromolecules of rubber into a three-dimensional network structure to improve the performance of rubber. [0003] The Chinese utility model patent with the existing authorized announcement number CN205704914U discloses a new type of vulcanizing machine, including a fra...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: after the production of the vulcanizer is completed, the shape of the heating element has been fixed. Since the heating element has a certain shape, there will be a gap between the rubber facing the heating element and the rubber far away from the heating element. The difference in heating of the rubber at the edge is particularly obvious. The vulcanizer has the problem of uneven heating of the rubber, which affects the vulcanization quality of the rubber product.
