Abstract

The invention discloses an air-discharging and air-filling device and a production technology thereof for molding sulfuration molds of rubber injection hollow products and belongs to the technical field of rubber product technology. The air-discharging and air-filling device comprises a compression molding sulfuration mechanism and a mold air-discharging and hollow air-filling mechanism. The moldair-discharging and hollow air-filling mechanism comprises a support, a cylinder, an oil cylinder body and a hydraulic station. The support is an annular rack with a through hole in the middle. The cylinder is fixed to an annular table surface of the support. The oil cylinder body is fixed to the bottom of the annular table surface of the support. The cylinder and the oil cylinder body are connected with a cylinder piston and an oil cylinder piston of the same piston rod in an internally-arranged manner respectively. The top of the cylinder communicates with the mold inner cavity of the compression molding sulfuration mechanism through an air pipe. The oil cylinder body is divided into an upper cavity body and a lower cavity body by the oil cylinder piston. The upper cavity body and the lower cavity body communicate with the hydraulic station respectively through an oil pipe. The air-discharging and air-filling device is integrated through the same piston rod; high pressure oil flow isadjusted; operation speed of the piston can be controlled; air-filling flow can be satisfied; and then air-filling pressure and air-discharging vacuum degree requirements are reached.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to an air discharge device for molding vulcanization molds of rubber injection hollow products and a production process thereof. Background technique [0002] Usually rubber injection hollow product mold exhaust, hollow inflatable molding vulcanization process, set up two sets of devices, respectively is the vacuum exhaust station and high pressure, high temperature gas supply device, the vacuum exhaust station is composed of a vacuum pump, condensation tank and related pipelines, high pressure 1. The high-temperature gas supply device is composed of an air compressor, a gas booster, a gas heater and related pipelines. The exhaust and inflation device is connected to the air inlet of the product mold through a proportional electronically controlled three-way valve. The exhaust and inflation device It works alternately, which makes the device occupy a large area, ...
