Description

Technical Field

[0001] The present invention relates to the technical field of casting molds, and specifically relates to a casting mold device for the production of rubber roller iron cores. Background Art

[0002] A rubber roller is a rubber product widely used in industrial production, usually composed of a metal core (such as steel or cast iron) and an outer elastic rubber layer. It plays key roles such as conveying, pressing, heat transfer, printing, etc. in many industries. The rubber roller includes an iron core, and when producing the iron core, a casting mold is required to shape the iron core.

[0003] After retrieval, the application number is "CN201922196778.5", specifically a casting mold device for the production of rubber roller iron cores. The operator slides and sleeved the upper mold into the limit slot of the lower mold through a connecting rod to connect the upper mold and the lower mold. After connection, the operator injects injection liquid through the liquid injection pipe, and the injection liquid enters the upper mold and the lower mold for molding.

[0004] When pouring and molding the iron core, molten metal needs to be poured into the mold through the pouring port. During the pouring process, since manual pouring is carried out, when the pouring speed is too fast, the impact force of the metal liquid is too large, splashing from the pouring port to the surrounding area. The metal liquid splashes onto the upper surface of the pouring port. If not cleaned in time, it is easy for the residual metal to oxidize or mix with impurities, which will be involved in the cavity during the next pouring, resulting in internal pores or doping in the casting and poor production quality of the iron core. Summary of the Invention
