The vulcanization of rubber is the last process of rubber processing. The conversion of unvulcanized rubber to vulcanized rubber can give rubber various valuable physical properties. Rubber vulcanizing press is a press with a heating function. Rubber vulcanizing machine is the main equipment in the rubber industry. No matter which rubber factory, there will be different types of rubber vulcanizing machines. Next, we will introduce its related content.

What is the working principle of a rubber vulcanizing press?
1. When the motor of the rubber vulcanizing press is running, the oil enters the oil pump from the oil filter of the oil storage tank and enters the control valve through the oil pump drain pipe. If the hand control valve is in the closed position, the oil enters the cylinder through the control valve and the oil pipe. Drive the plunger and the lower template platform to rise.
2. When the pressure of the rubber vulcanizing press reaches the upper limit specified value, the electric contact pressure gauge contacts control to stop the operation of the oil pump motor, and the one-way valve is automatically closed to maintain the pressure in the oil cylinder.
3. When the pressure of the rubber vulcanizing machine drops to the required minimum working pressure, the electric contact pressure gauge contacts control the operation of the oil pump, and the oil pressure rises again until the vulcanization heating time is completed.
4. When the rubber vulcanizing press stops working, the mold is opened to take the workpiece, and the mold is fixed between the upper and lower platforms. Generally, it is heated with an automatic temperature control electric heating tube. After the rubber is heated for a few minutes, it will be vulcanized and fixed in performance and shape.
What is the function of a rubber vulcanizing press?
A rubber plate vulcanizing machine is mainly used to vulcanize flat tape. The rubber vulcanizing machine has the advantages of high pressure per unit area of the hot plate, reliable operation of the equipment, and less maintenance. At present, rubber vulcanizing presses are widely used in metallurgy, mining, power plants, ports, building materials, chemicals, and other fields, and are also suitable for the vulcanization of anti-corrosion and heat-resistant tapes. As long as the rubber vulcanizing machine has a common tap water source on-site, it can quickly cool the heating plate by passing water after the vulcanization is completed. The main function of the rubber vulcanizing press is to provide the pressure and temperature required for vulcanization. The pressure is generated by the hydraulic system through the hydraulic cylinder, and the temperature is provided by the heating medium. In the rubber industry, the column-type rubber vulcanizing press is an earlier model. The rubber vulcanizing press used in my country in the past is mostly column structure, but now it mostly adopts frame structure.
