Automobile brake chamber rubber separation film circulation forming device

Abstract

The invention discloses an automobile brake chamber rubber separation film circulation forming device comprising a vacuum vulcanizing press machine, an injection vulcanizing press machine, a de-molding mechanism, and a rubber separation film molding mold. The vacuum vulcanizing press machine is used for primary vulcanizing treatment of the rubber separation film. The injection vulcanizing press machine is used for secondary vulcanizing treatment. The de-molding mechanism is used in separation operations of a pressing ring and a lower mold of the rubber separation film molding mold. According to the invention, a traditional secondary vulcanization molding process is changed. A rubber material is injected into a mold cavity by the injection device, and vulcanizing treatment is carried out simultaneously during feeding. The automation degree is high, labor investment is saved, product production efficiency is high, product quality is stable, and production cost is reduced.

Description

technical field [0001] The invention relates to a secondary injection vulcanization molding device for a rubber diaphragm of an automobile brake air chamber, in particular to a cycle molding device which adopts an injection vulcanization press for secondary vulcanization treatment. Background technique [0002] The existing automobile brake air chamber rubber diaphragm secondary vulcanization molding device has been disclosed in the Chinese patent No. 201010541774.7. In the above-mentioned document, two vacuum vulcanization presses, a demoulding mechanism, and a rubber diaphragm molding die are disclosed. One vacuum vulcanization press is used for the primary vulcanization treatment of the rubber diaphragm, the second vacuum vulcanization press is used for the secondary vulcanization treatment of the rubber diaphragm, and the demoulding mechanism is used for the separation operation of the pressure ring and the lower mold in the rubber diaphragm forming mold; There is an...

Problems solved by technology

[0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a rubber diaphragm circulation molding device for automobile brake chambers, which breaks the traditional secondary vulcanization molding process under the premise that the rubber diaphragm primary vulcanization molding process remains unchanged Vulcanization molding process, the injection machine injects rubber into the mold cavity, without manual feeding, and automatically completes the secondary vulcanization treatment, reduces labor input, improves the production efficiency of the air chamber rubber diaphragm, and reduces production costs; and this The molding device is heated immediately while injecting the material, and the fluidity of the rubber material is good, which avoids the localization of the lower rubber layer of the vulcanized air chamber diaphragm caused by the mold extruding the rubber material after the secondary vulcanization process in the traditional secondary vulcanization process deformation, dislocation or uneven thickness of the lower rubber layer, and then affect the quality of the finished product; in addition, the present invention sets the station according to the rubber diaphragm processing procedure, and in order to improve the quality of the rubber diaphragm, the processing of primary vulcanization and secondary vulcanization The time and temperature will be different. When the production efficiency of the vacuum vulcanization press is more than twice that of the injection vulcanization press, the station arrangement of one vacuum vulcanization press and two injection vulcanization presses greatly shortens the production of rubber diaphragms. cycle, thereby improving equipment utilization and further improving production efficiency
