AI Technical Summary

Technical Problem

During the die-casting process of ultra-large integrated automobile chassis, the flow distance of the alloy liquid is too long, resulting in unstable mechanical properties. In the prior art, the opening of the die-casting mold causes air to be rolled into the cavity when the alloy liquid is poured into, causing air hole defects.

Method used

The double-pack super-large integrated automotive chassis die-casting mold is used, including fixed mold and moving mold, two pressure chambers and shunt cones are set up, and the vacuum suction system is combined to ensure that the alloy liquid is quickly filled in the closed cavity and removes air holes.

Benefits of technology

The shortest alloy liquid flow is achieved, ensuring high vacuum die casting, completely removing pores in the die casting, and improving part performance and overall quality.

Abstract

The double-material-cake ultra-large type integrated automobile chassis die-casting die is characterized in that a fixed die and a movable die are included, an automobile chassis cavity is formed between the fixed die and the movable die, two pressure chambers are arranged on the fixed die and correspond to the front center and the rear center of the automobile chassis cavity respectively, and the two pressure chambers are arranged in the fixed die and correspond to the front center and the rear center of the automobile chassis cavity respectively; two spure spreaders corresponding to the pressure chambers are arranged on the movable die, springs are arranged at the rear ends of the spure spreaders, the front ends of the spure spreaders block the front ends of the pressure chambers in a natural state, and the rear ends of the spure spreaders are movably limited on the movable die through screws; and a water inlet communicated with the automobile chassis cavity is formed between the spure spreader and the pressure chamber under the rapid injection state of the punch. The die casting mold has the beneficial effects that the die casting mold can adapt to the structural characteristics of an ultra-large integrated die casting, and the shortest flow of alloy liquid on the die casting can be guaranteed; and it can be ensured that the die-casting die cavity is vacuumized in a closed state, air holes in a die-casting piece can be completely removed, the part performance is improved, and the use requirement is met.
