Description

Electromagnetic heating device suitable for vulcanizer

Technical Field

The utility model relates to the technical field of vulcanizing machines, in particular to an electromagnetic heating device suitable for a vulcanizing machine.

Background

The vulcanizing machine is a machine for vulcanizing various rubber and plastic products. The rubber and plastic products are molded by arranging a die on a workbench with a heating device, heating a vulcanized material and pressing the die. The traditional heating device adopts an electric heating tube to generate heat, and although the heating power is high, the heat can be scattered towards the periphery, the electric heating conversion rate is low, and the energy utilization rate is not high. Therefore, electromagnetic heating has been proposed in the market, and the rubber support of the mold is electromagnetically heated by an electromagnetic field generated by the energizing coil.

The base region facing away from the mold is also heated by the electromagnetic field due to the fact that the electromagnetic field is omnidirectionally diffused around. Therefore, the supporting layer arranged below the electric coil layer in the prior art is embedded with a plurality of electromagnets, and the second electromagnetic field generated by the electromagnets is utilized to block the diffusion of the electrified coil towards the base. However, after practical experiments, it is found that, because the base needs to have enough supporting strength, a certain arrangement interval exists between the electromagnets, and a weak area with a certain poor shielding capability exists in the arrangement interval, so that the supporting layer cannot completely block the electromagnets of the electric coil layer from diffusing towards the base, and after long-time use, the base can be heated up due to electromagnetic field heating, and the normal operation of the vulcanizing machine is affected. Therefore, further improvements are needed.
