Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tire mold technology, specifically relating to a tire vulcanization mold. Background Technology
[0002] Various electric heating vulcanization technologies have emerged in the market. Some of these technologies use a heating film as a heat source to heat the mold and provide the heat required for the vulcanization process, thus completing the tire vulcanization. However, in conventional designs, the heating film only has a single layer of insulation material on the outside, without any other protective materials. During storage, transportation, and maintenance, the mold is prone to bumps, impacts, and squeezing, which can damage the heating film and affect the mold's safety and lifespan. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a tire vulcanizing mold, including a tread block, a slider, and a guide ring. The tread block is fixedly installed on the inner side of the slider, the slider is slidably connected to the inner side of the guide ring, and a heating film is provided on the outer side of the guide ring for heating the tread block. A protective layer is provided on the outer side of the heating film.
[0004] Furthermore, the protective layer includes a flexible protective layer and a rigid protective layer, with the rigid protective layer disposed on the outside of the flexible protective layer.
[0005] Preferably, the flexible protective layer has a thickness of 5-10 mm and is made of one of the following materials: aerogel felt, high-temperature foam, PTFE board, ceramic fiber felt, silicone, and glass fiber felt. Preferably, the rigid protective layer has a thickness of 2-3 mm and is made of steel.
[0006] Furthermore, an insulation layer is provided on the outside of the protective layer, and the insulation layer material is one of aerogel felt, high-temperature foam, ceramic fiber felt, and glass fiber felt.
[0007] Furthermore, a heat-equalizing layer is provided between the heating film and the guide ring, and the heat-equalizing layer is bonded to the guide ring.
[0008] Furthermore, the heat spreader material is one of graphene, aluminum, copper, molten salt, graphite, or thermally conductive silicone.
[0009] Furthermore, a temperature measuring hole is provided on the upper or lower end face of the guide ring, and a temperature measuring element is provided inside the temperature measuring hole.
[0010] The technical solution provided by this utility model has the following advantages compared with the prior art: This utility model provides a tire vulcanizing mold, including a tread block, a slider, and a guide ring. The tread block is fixedly installed on the inner side of the slider, and the slider is slidably connected to the inner side of the guide ring. A heating film is provided on the outer side of the guide ring to heat the tread block. A protective layer is provided on the outer side of the heating film to protect the heating film and prevent bumps, impacts, and squeezing during storage, transportation, and maintenance of the mold, thereby improving the safety and service life of the mold.
[0011] Furthermore, the insulation layer, protective layer, heating film, and heat equalization layer are sequentially arranged on the outer side of the guide ring from the outside to the inside. The insulation layer located on the outside of the heating film prevents heat loss, and the heat generated by the heating film is evenly distributed to the inside through the heat equalization layer, resulting in efficient heating and more uniform mold temperature.
