Injection molding vulcanizing unit for preventing rubber material from being vulcanized in pouring gate

Abstract

The invention discloses an injection molding vulcanizing unit for preventing a rubber material from being vulcanized in a pouring gate. An injection machine comprises a machine rack, a main pouring gate and an injection moving seat, the main pouring gate and the material injection moving seat are arranged on the rack, and the material injection moving seat can be driven to move relative to the rack so as to approach the main pouring gate; the vulcanizing machine comprises a machine rack, a vulcanizing part, a vulcanizing moving seat and a heating assembly; the vulcanizing part, the vulcanizing moving seat and the heating assembly are arranged on the rack, and the vulcanizing moving seat can move relative to the rack to approach the vulcanizing part; the mold group is driven to move to the material injection moving seat or the vulcanizing moving seat; the mold group can be driven by the material injection moving seat, so that the main pouring gate is communicated with the interior of the mold group; and the mold group can also be driven by the vulcanizing moving seat, so that the vulcanizing part is connected with the interior of the mold group, and the mold group is heated by the heating assembly. The injection molding vulcanizing unit can prevent rubber from being vulcanized in the pouring gate.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to an injection molding vulcanization unit which prevents rubber from being vulcanized in a runner. Background technique [0002] Injection molding is one of the most common processes in the rubber industry. Part of the rubber needs to be added with a vulcanizing agent to vulcanize the rubber during the injection molding process and heated appropriately to vulcanize the rubber. The vulcanized rubber has a relatively high High strength, better elasticity, wear resistance and corrosion resistance, the molded rubber material has good physical properties, and this part of the rubber is usually molded and vulcanized simultaneously through an injection molding vulcanizer. [0003] An existing injection molding vulcanizer generally includes a barrel, an injection runner, a mold set, and a heating assembly; the injection runner communicates with the inside of the barrel and the mold set, thro...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned existing injection molding vulcanizers, the rubber material may be vulcanized in the injection runner, that is, before being poured into the mold set, causing the rubber material to solidify in the injection runner and produce dead material. And the problem of high defect rate of injection molded rubber parts, the purpose of the present invention is to provide an injection molding vulcanization unit that prevents rubber from being vulcanized in the runner.
