Problems solved by technology
At present, there are many ways of electric heating, usually divided into resistance heating, induction heating, arc heating, electron beam heating, infrared heating and medium heating, etc. Different electric heating methods have different mold production costs, among which , the cost of resistance heating is the lowest. However, when resistance heating is selected, in view of the defects of resistance heating itself, the heat conduction efficiency is low, especially the tire mold is divided into a tire upper mold and a tire lower mold, and heat transfer is carried out between the two It will also lose a certain amount of heat, which will undoubtedly further reduce the overall heat conduction efficiency of resistance heating

The invention discloses an electric heating mold for integrally forming a rubber tire. The electric heating mold structurally comprises an upper mold, a middle mold and a lower mold which are sequentially arranged from top to bottom; the electric heating mold further structurally comprises two tire molds; the tire molds comprise a tire upper mold and a tire lower mold which are engaged up and down; electric heating plates are arranged in the upper mold, the middle mold and the lower mold; the two tire molds are respectively arranged between the upper mold and the middle mold and between the middle mold and the lower mold; a closed contact surface is arranged at the joint of the tire upper mold and the tire lower mold; a positioning piece and a vacuum groove are sequentially formed on the contact surface from outside to inside; a heat conduction piece is arranged in the vacuum groove. The heat conduction efficiency between the tire molds is improved.
Description
Technical field: [0001] The invention relates to the technical field of tire production, in particular to an electric heating mold for integrally forming a rubber tire. Background technique: [0002] As we all know, after entering the 1990s, the tire structure gradually developed towards the radial direction and the active die technology became more mature, and the hot plate vulcanizing machine was widely popularized. Compared with the previous generation steamer type vulcanizer, the hot plate type vulcanizer has the characteristics of less steam consumption and high heat transfer efficiency. At present, there are many ways of electric heating, usually divided into resistance heating, induction heating, arc heating, electron beam heating, infrared heating and medium heating, etc. Different electric heating methods have different mold production costs, among which , the cost of resistance heating is the lowest, but when resistance heating is selected, in view of the defects ...
