Problems solved by technology

The existing solution is to design a specific cooling channel in the mold for a specific aluminum-based piston. However, this solution requires a one-to-one design, which lacks flexibility. At the same time, sometimes the processing of a specific cooling channel is relatively difficult and expensive also very high

Abstract

The invention discloses a mold rapid cooling system and method for aluminum-based piston casting, and relates to the field of aluminum-based piston casting. Aluminum-based pistons include aluminum alloy pistons or aluminum-based composite pistons. The mold rapid cooling system includes top molds, side molds and core molds, and top molds, side molds and core molds are respectively equipped with top mold cooling channels and core mold cooling The water channel and side mold cooling channel, the top mold cooling channel is connected with the top mold cooling system, the core mold cooling channel is connected with the mandrel cooling system, the side mold cooling channel is connected with the side mold cooling system; Adjust the opening of the bypass water valve to realize the controllable cooling of each split mold. The invention is aimed at the casting mold of the aluminum-based piston, and realizes the controllable and variable cooling speed of each split mold while rapidly cooling the mold.

Description

technical field [0001] The invention relates to the field of aluminum-based piston casting, in particular to a mold rapid cooling system and method for aluminum-based piston casting. Background technique [0002] Aluminum-based pistons generally refer to aluminum alloy pistons or aluminum-based composite material pistons. Such pistons are generally cast in split molds, which commonly include top molds, core molds and side molds. After pouring, the mold is generally cooled naturally, the cooling time is longer and the production efficiency is lower. In the prior art, there are cooling water channels in the mold to speed up the cooling rate. However, for the molds corresponding to different parts of the aluminum-based piston, it is hoped that according to the characteristics of the parts, different cooling rates can be achieved to achieve the purpose of sequential solidification. The existing solution is to design a specific cooling channel in the mold for a specific aluminum...
