Abstract

The invention discloses a vulcanizing machine hot plate based on electromagnetic heating. The vulcanizing machine hot plate is characterized by comprising a first metal plate, a first copper plate anda second metal plate, wherein the first metal plate, the first copper plate and the second metal plate are superimposed and fixed from bottom to top in sequence, an induction coil is positioned belowthe hot plate, the thickness of the first metal plate is larger than 0 mm and smaller than or equal to 2 mm, a magnetic induction vortex dense region on the first metal plate is removed to form a hole, a lower heat insulation layer is arranged between the induction coil and the first metal plate, the lower heat insulation layer is fixedly connected with the first metal plate, and side heat insulation layers are fixedly arranged on the periphery of the first metal plate, the first copper plate and the second metal plate. The hot plate has the advantages that the temperature difference is reduced through multiple layers and multiple times, so that the temperature of the surface of the hot plate is close to the uniform temperature, and the vulcanization quality of rubber is improved; and moreover, the hot plate realizes heat transfer through the copper plate, so that the heat conduction speed is high, and the heating speed of the vulcanizing machine hot plate is further improved.

Description

technical field [0001] The invention relates to a hot plate structure in a vulcanizer, in particular to a hot plate of a vulcanizer based on electromagnetic heating. Background technique [0002] The hot plate of the vulcanizer is an important part of rubber vulcanization. The traditional hot plate of the vulcanizer is usually heated by steam heating, electric heating, etc., and its heating speed is slow and the efficiency is low. Electromagnetic heating technology is a rapid heating method through electric-magnetic-thermal conversion, which has fast heating speed and high efficiency. With the application of electromagnetic heating technology, the heating speed of the hot plate of the vulcanizer has been greatly improved, but the current hot plate of the vulcanizer has uneven surface temperature and excessive temperature difference, which directly affects the vulcanization quality of the rubber. Contents of the invention [0003] The technical problem to be solved by the ...
