Constant-temperature heating platform for vulcanization

Abstract

The invention provides a constant-temperature heating platform for vulcanization. The constant-temperature heating platform for vulcanization comprises a heating table body, wherein the heating tablebody comprises a first plate body and a second plate body arranged up and down; a constant-temperature oil cavity is arranged in the second plate body; constant-temperature hot oil is injected into the constant-temperature oil cavity; multiple heat conducting holes penetrating through the upper surface and the lower surface of the first plate body and communicating with the constant-temperature oil cavity are formed in the first plate body; heat conducting pillars stretching into the constant-temperature hot oil are arranged in the heat conducting holes, are adaptive to the heat conducting holes and are in sealed connection with the inner walls of the heat conducting holes; multiple hole parts are formed in the first plate body and are arranged in one-to-one correspondence to the multipleheat conducting holes; each hole part comprises multiple heating holes distributed circumferentially around the heat conducting holes; and electromagnetic coils are arranged in the heating holes. According to the constant-temperature heating platform for vulcanization provided by the invention, electric heating and oil heating are combined, so that an effect on heating at constant temperature canbe achieved; and through arranging a third plate body for carrying out heat insulation treatment for the first plate body and the second plate body, the ambient temperature and the medium temperatureof the first plate body can be effectively stay the same.

Description

technical field [0001] The invention relates to the technical field of vulcanization heating, in particular to a vulcanization constant temperature heating platform. Background technique [0002] The vulcanizer is the most commonly used processing equipment in the rubber industry. It is used to produce rubber seals. Rubber seals need to generate high temperature and high pressure conditions during processing. At present, the way to generate high temperature in the market is to heat the heating platform by means of electric heating tube heating, oil heating or steam heating; There is a temperature difference between the parts, so after heating the heating platform, the heat will coalesce toward the middle and upwards, which also leads to a larger temperature difference on the template; the oil heating scheme is to heat the heatable kerosene to a certain temperature, and then use a pump to pump the hot kerosene to the heating plate. The inner side of the plate circulates, the...

At present, the way to generate high temperature in the market is to heat the heating platform by means of electric heating tube heating, oil heating or steam heating; There is a temperature difference between the parts, so after heating the heating platform, the heat will coalesce toward the middle and upwards, which also leads to a larger temperature difference on the template; the oil heating scheme is to heat the heatable kerosene to a certain temperature, and then use a pump to pump the hot kerosene to the heating plate. The inner side of the plate circulates, thereby producing the effect of high temperature, because there is a large distance between the oil holes circulating on the heating platform, and at the same time, the oil temperature in different areas in the oil guide pipe is different, so a dynamic balance of temperature cannot be achieved, and it will also lead to an increase in the temperature difference on the heating platform ;The principle of steam heating is the same as that of oil heating, and the generated steam is circulated through the template to produce high temperature effect

Since the steam is easy to liquefy and the heat transfer effect is poor, the temperature difference between the steam inlet and the steam outlet is larger, and it is difficult to achieve the effect of constant temperature heating
