Background
The vulcanizing machine is the most common processing equipment in the rubber industry, and is used for producing rubber sealing elements which need to generate high-temperature and high-pressure conditions in the processing process. The method for generating high temperature in the current market is to heat a heating platform by means of electric heating tube heating, oil heating or steam heating; the electric heating pipes are inserted into the same heating platform for heating, and because different parts of the electric heating pipes have temperature differences, heat can be coalesced towards the middle and upwards after the heating platform is heated, so that the temperature difference on the template is increased; the oil heating scheme is that the heatable kerosene is heated to a certain temperature, and then the hot kerosene is pumped into the heating plate by a pump to circulate, so that a high-temperature effect is generated; the steam heating is the same as the principle of oil heating, and the generated steam circulates through the template to generate a high-temperature effect. Because the steam is easy to liquefy and the heat-carrying effect is poor, the temperature difference between the steam inlet and the steam outlet is larger, and the constant-temperature heating effect is difficult to achieve. The surface temperature of the periphery of the heating platform in contact with air is quickly dissipated during heating, and the central temperature is slowly dissipated, so that the surface temperature of the heating platform is uneven.
