AI Technical Summary

Technical Problem

When casting medium to large-sized castings with complex structures, the molten metal may not be able to fully fill thin-walled or narrow areas, resulting in shrinkage cavities or porosity defects in the casting.

Method used

A metal casting device is used to electromagnetically heat and stir the molten metal in the mold through an induction coil. The connection position between the induction coil and the copper busbar is adjusted by a power source, so that the molten metal gradually cools from bottom to top, and the upper layer of molten metal fills the shrinkage space of the lower layer.

Benefits of technology

It effectively avoids shrinkage cavities or porosity defects in thin-walled or narrow parts of castings, and is suitable for casting medium and large-sized castings with complex structures.

Abstract

The application provides a metal casting device and relates to the technical field of metal casting. The purpose is to solve the problem that the castings cast by the prior art are prone to defects at thin walls. The technical scheme adopted is as follows: a metal casting device, comprising: a power supply system; the power supply system is connected with a vertical induction coil through a first output terminal and a second output terminal; the first output terminal is a first copper bar extending in the up-down direction and is connected with the induction coil through a first connecting mechanism; the first connecting mechanism is adapted to drive a first power source to move up and down. The metal liquid in the mold can be heated and stirred, so that the metal liquid can fully fill the thin wall; and the heating area can be flexibly adjusted, so that the metal liquid in the mold can gradually cool from bottom to top, and the shrinkage generated when the lower metal liquid cools and solidifies can be effectively filled by the upper metal liquid, thereby avoiding the shrinkage cavity or shrinkage porosity of the casting.
