Abstract

The invention discloses a production mold for hollow air-free tires, which belongs to the field of tire molds. The invention discloses a production mold for hollow air-free tires, which includes an outer mold assembly and an inner disk assembly. During injection molding, the The inner disc assembly is located at the center of the inner cavity of the outer mold assembly; the inner disc assembly includes an upper disc body and a lower disc body, and the upper disc body and the lower disc body are provided with engaging recesses that cooperate with each other. Groove, each of the snapping grooves is provided with a boss, and the bosses are snapped into the snapping grooves during injection molding. After the injection molding is completed, only the upper plate body and the lower plate body need to be disassembled, and the boss in the middle can be easily taken out. The disassembly is convenient and the production efficiency is high.

Description

Technical field [0001] The present invention relates to the field of tire molds, in particular to a production mold for hollow-core pneumatic tires. Background [0002] In the use of mold for the production of hollow tires, the use of injection molding once molding to make the production of tires with excellent mechanical properties, in order to achieve the hollowness inside the tire, it is necessary to install a boss inside the tire during injection molding, so that the cam position is not injected during injection molding, and the boss can be removed after the injection is completed to obtain the hollow tire. [0003] In the production of hollow pneumatic tires, the existing injection mold can not easily remove the internal raised mold, so that the production efficiency can not be guaranteed. Contents of the Invention [0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose a production mold for holl...
