Abstract

The invention discloses an automobile diesel pump tail gas treatment pump diaphragm and a vulcanization forming mold and manufacturing method of the automobile diesel pump tail gas treatment pump diaphragm and belongs to the technical field of processing of rubber with metal and nonmetal. The processing mold of the automobile diesel pump tail gas treatment pump diaphragm comprises an upper mold and a lower mold. The lower surface of the upper mold is provided with an upper mold cavity. The upper surface of the lower mold is provided with a lower mold cavity. A clamping groove is perpendicularly arranged below the lower mold cavity. A rubber cavity is formed after the upper mold cavity and the lower mold cavity are combined. A circle of O-shaped tearing ribs are arranged, along the edge of reinforcing fiber, on the inner surface of the rubber cavity. According to the automobile diesel pump tail gas treatment pump diaphragm and the vulcanization forming mold and manufacturing method of the automobile diesel pump tail gas treatment pump diaphragm, through the improvement on the framework structure, the reinforcing fiber structure, the mold structure and a molding process, rubber flashes on the surface of a manufactured product can be easily torn off, the product quality and the production efficiency are improved, the manufacturing cost is reduced, and meanwhile the problem that the reinforcing fiber in the pump diaphragm is prone to wrinkling is solved.

Description

technical field [0001] The invention belongs to the technical field of rubber, metal and non-metal processing, and more specifically relates to an automobile diesel pump tail gas treatment pump membrane combined with EPDM rubber, metal and reinforcing fibers, as well as a vulcanization molding mold and a manufacturing method thereof. Background technique [0002] With the tightening of the country's mandatory regulations on engine emissions, higher requirements have been put forward for the exhaust emission level of diesel engines. Vehicle diesel engines sold in the domestic market must be upgraded accordingly. At present, China has implemented the emission regulations of the National III standard for vehicle engines nationwide. At the same time, Beijing, Shanghai, and the Pearl River Delta region have implemented the emission regulations of the National IV standard, and will soon implement the National IV standard nationwide. [0003] For vehicle diesel engines, there are t...
