Abstract

The application relates to a large thin-wall aluminum alloy middle control support die casting die for an automobile and a process, the die comprises a fixed die and a movable die, square guide columns are arranged in the four corner regions of the opposite surfaces of the fixed die sleeve plate and the movable die sleeve plate, limiting grooves corresponding to the square guide columns are arranged in the four corner regions of the opposite surfaces of the movable die sleeve plate and the fixed die sleeve plate, and wear-resistant plates are arranged in the limiting grooves. The process comprises the following steps: S1, die clamping; S2, injection; S3, cooling and solidification; S4, die opening; and S5, part taking and cleaning. By optimizing the positioning system of the die casting die and key parameters of the die casting process, the application can guarantee the continuous production and size precision of the large thin-wall middle control support die casting, can realize low-cost and self-adaptive mold temperature regulation and control, and can effectively control the deformation of the thin-wall middle control support.
