BCS piston compression molding rubber mold

Abstract

The invention discloses a BCS piston compression molding rubber mold, and relates to a mold. An upper mold mounting plate is arranged outside an upper mold in a sleeving mode, a lower mold mounting plate is arranged outside a lower mold in a sleeving mode, the upper mold is arranged at the upper end of the lower mold, and a disc spring is arranged in the upper mold. The upper mold comprises an upper outer mold plate and an upper mold core. The upper outer mold plate is provided with an upper outer mold plate snap spring groove, a first multi-stage decreasing boss snap spring mounting groove, a disc spring mounting chamber and an upper mold core placing groove. The upper mold core is attached to the upper outer mold plate. The upper mold core is provided with an upper mold core snap spring groove, a disc spring mounting protrusion, an annular protrusion and a stepped groove. The upper mold mounting plate is provided with an upper mold mounting chamber, a first-stage boss mounting groove, an upper mold pin and an upper mold connecting hole. The lower outer mold plate is provided with a mounting plate mounting groove, a placing groove, a lower mold core groove, a lower groove and a mounting groove. The lower mold core is provided with a stepped shoulder, a mounting ring block and a fourth snap spring mounting groove. The purpose of manufacturing a rubber piston through vulcanization is achieved, and the produced product is high in compactness, good in size consistency and low in manufacturing cost.

Description

technical field [0001] The invention relates to a mold, in particular to a BCS piston molding rubber mold. Background technique [0002] With the upgrading of automobile technology, automatic transmission vehicles have entered people's lives. While automatic transmission technology is being accepted by people, the performance of automatic transmission auto parts has also attracted people's attention, especially the rubber piston in the clutch. [0003] The rubber piston is a key component in the automatic transmission, which needs to seal the hydraulic oil and play the role of pressure transmission during service. During its working process, it is constantly subjected to high pressure, and the meshing of the gears must also be achieved, and it can perform up to one million reciprocating movements during service. Therefore, the manufacture of rubber pistons is particularly important. [0004] How to ensure the compactness and dimensional consistency of rubber vulcanization ...

AI Technical Summary

Problems solved by technology

[0006] One is cold runner injection molding. Through research, it is found that the products of cold runner injection molding have good compactness, but the cost of vulcanization molds and vulcanization equipment is very high;

[0007] The other is transfer molding, the pressure loss of transfer molding is large, resulting in poor product compactness
