Problems solved by technology
However, in the field of traditional rubber and rubber injection molding, due to the physical properties of rubber, it is difficult to guarantee the product release efficiency of the hollow structure. Usually, the demoulding method of such products is to use components to assemble; Glue to vulcanization and demoulding; finally, disassemble the previously assembled components to achieve demoulding
This type of demoulding efficiency is extremely low, and it is difficult to guarantee the quality of the product

The invention relates to a tire mold, an internal hollow tire and a tire manufacturing technology. In the tire manufacturing process, firstly, a second mold body is pressed onto a first mold body, sothat an injection mold cavity is formed among the second mold body, the first mold body and a mold core; and then a raw material is poured into an injection hole, and gas in an injection mold cavity is exhausted by utilizing an exhaust hole, so that the raw material is pressed into the injection mold cavity. Due to the fact that protrusions arranged towards the interior of the injection mold cavity are arranged on the mold core, an internal hollow structure can be correspondingly formed on the inner side of a tire product formed in the injection mold cavity. After material pouring, the secondmold body and the first mold body are separated for mold opening operation, at the moment, the mold core loses the abutting force of the second mold body, and under the elastic force of an elastic piece, the tire product is driven to be ejected out of the first mold body together; and finally, the tire product is stripped outwards from the mold core so that the tire product can be completely and quickly demolded. The mold core in a movable state is arranged in the tire mold, so that quick demolding of the inner hollow tire is realized.
Description
technical field [0001] The invention relates to the technical field of tires, in particular to a tire mold, an inner hollow tire and a tire manufacturing process. Background technique [0002] Rubber injection mold is a common equipment used to make rubber products. The rubber raw material is injected into the mold, vulcanized at high temperature, and made into rubber products according to the shape of the cavity in the mold. Most of the current production processes are to make it into a solid tire, but the material consumption of the solid tire is relatively large, resulting in an increase in cost. At the same time, its processing procedure is also very complicated and time-consuming. [0003] As people now have higher requirements for product styles and features, it is necessary to use a variety of different types of hollow structures on the same product. However, in the field of traditional rubber and rubber injection molding, due to the physical properties of rubber, i...
