Circular moulding device of rubber diaphragms for automobile brake chambers

Abstract

The invention discloses a circular moulding device of rubber diaphragms for automobile brake chambers. The device comprises a vacuum vulcanizing press, an injection vulcanizing press, a demoulding mechanism and a rubber diaphragm moulding mould, wherein the vacuum vulcanizing press is used for primary vulcanization treatment of the rubber diaphragms; the injection vulcanizing press is used for secondary vulcanization treatment; and the demoulding mechanism is used for separating compression rings from lower moulds in the rubber diaphragm moulding mould. The device breaks through a traditional secondary vulcanization moulding process, injects glue into a mould cavity via an injection machine, carries out vulcanization treatment while feeding, has high degree of automation, saves manpower input, has high product production efficiency and stable quality and reduces the production cost.

Description

[0001] technical field [0002] 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. [0003] Background technique [0004] The existing automobile brake air chamber rubber diaphragm secondary vulcanization molding device has been disclosed in the Chinese patent No. 201010541771.3. 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...

Problems solved by technology

[0006] 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, thereby affecting the quality of the finished product; in addition, the present invention sets the station according to the rubber diaphragm processing procedure, which shortens the production cycle of the rubber diaphragm to the greatest extent, thereby improving the utilization rate of the equipment , further improving production efficiency
