Electromagnetic induction heating device for tire vulcanization outer mould

Abstract

The invention relates to an electromagnetic induction heating device for a tire vulcanization outer mould, belonging to the field of tire production equipment. The electromagnetic induction heating device consists of an upper side plate heating unit, a lower side plate heating unit and a middle mould sleeve heating unit. The upper side plate heating unit comprises a base plate, a disc-shaped electromagnetic coil and a coil cover plate, wherein an upper side plate is provided with a ring-shaped groove; the base plate is laid in the ring-shaped groove; the disc-shaped electromagnetic coil is arranged on the base plate; the coil cover plate is arranged at the upper part of the disc-shaped electromagnetic coil. The lower side plate heating unit comprises a base plate, a disc-shaped electromagnetic coil and a coil cover plate, wherein a lower side plate is provided with a ring-shaped groove; the base plate is arranged at the bottom of the ring-shaped groove; the disc-shaped electromagnetic coil is arranged on the base plate; the coil cover plate is arranged in the ring-shaped groove. The middle mould sleeve heating unit comprises an internal spacer bush, a column-shaped electromagnetic coil, a heat insulation layer and a shell, wherein the internal spacer bush is arranged at the periphery of a middle mould sleeve and is wound with the column-shaped electromagnetic coil; the heat insulation layer and the shell are sequentially arranged at the periphery of the column-shaped electromagnetic coil. The electromagnetic induction heating device is high in thermal efficiency, low in energy consumption and low in processing and manufacturing cost.

Description

technical field [0001] The invention relates to the field of tire production equipment, in particular to an electromagnetic induction heating device for a tire vulcanization outer mold. Background technique [0002] As we all know, the tire shaping vulcanizer is one of the most important process equipment in the tire industry. According to the heating method, there are mainly two types: steamer type and hot plate type. In the 1990s, with the gradual development of the tire structure towards the radial direction and the maturity of the movable mold technology, the hot plate type vulcanizing machine has been widely popularized and has gradually replaced the steamer type structure. Compared with the steamer type vulcanizer, the hot plate type vulcanizer has the characteristics of less steam consumption and high heat transfer efficiency, but this structure type does not fundamentally solve the long-standing drawbacks in the tire vulcanization process, and most of the heat of th...

Problems solved by technology

Compared with the steamer type vulcanizer, the hot plate type vulcanizer has the characteristics of less steam consumption and high heat transfer efficiency, but this structure type does not fundamentally solve the long-standing drawbacks in the tire vulcanization process, and most of the heat of the steam remains It is dissipated during the pipeline circulation process, and energy is wasted seriously. The steam heat in the upper and lower hot plates and the steam chamber of the middle mold casing needs to be conducted slowly to reach the pattern blocks, side plates and steel rings. Generally speaking, The warming process of the newly replaced mold takes 3 to 5 hours, and the heat transfer efficiency is very low. Moreover, due to the existence of the steam chamber, the processing and manufacturing cost of the outer mold is also increased, and the outer mold is also easily corroded by steam during long-term use. , the service life is affected
