Device for cyclically forming rubber diaphragm of automobile brake chamber

Abstract

The invention discloses a device for cyclically forming a rubber diaphragm of an automobile brake chamber. The device comprises a vacuum vulcanizing press, an injection vulcanizing press, a demolding mechanism and a rubber diaphragm forming mold, wherein the vacuum vulcanizing press is used for carrying out primary vulcanization processing on the rubber diaphragm, the injection vulcanizing press is used for carrying out secondary vulcanization processing, and the demolding mechanism is used for separating a pressing ring in the rubber diaphragm forming mold from a lower mold. According to the device, the traditional twice vulcanization forming process is broken through, a sizing material is injected into a mold cavity by an injection machine, and the vulcanization processing is carried out while feeding, so that the degree of automation is high, the labor input is reduced, the production efficiency and quality of products are high, and the 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
