Casting Mold Designing for Double-Chamber Throttle Valve

Abstract:

The structure and processing of double chamber throttle valve body castings were analyzed. Die-casting molding process scheme was established. The design of mold includes three core-drawing mechanisms. Considering the large parts surface area and the relatively small wall thickness and the requirement of parting, the gate was arranged on the casting bottom surface. For economy and die easy maintenance considerations, die-casting machine, mold, and mold standard parts should be standard parts. The designs of mold gating system and non-standard pieces were completed. Proved by actual production, the mold operated smoothly, without clamping stagnation, and the production of die castings meet delivery requirements.
