Runner plugging device for water-cooling die casting

Abstract

The invention provides a runner plugging device for water-cooling die casting. The runner plugging device is arranged on a base plate, a vertical runner communicated with a casting die is formed in a casting surface of the base plate, and a transverse runner communicated with the vertical runner in a sealed manner is formed in the base plate. The runner plugging device comprises an ejection rod and a plug, wherein a mounting channel is formed in the side surface of the base plate in the direction perpendicular to the vertical runner, the mounting channel is communicated with the vertical runner, the ejection rod penetrates through the mounting channel and can move along the mounting channel, one end of the ejection rod can extend into the vertical runner, the other end of the ejection rod extends out of the mounting channel, and the plug is connected to one end of the ejection rod and plugs the vertical runner through movement of the ejection rod. According to the runner plugging device for water-cooling die casting, the ejection rod is driven to move towards the vertical runner along the mounting channel, the plug connected to one end of the ejection rod is pushed to move to plug the vertical runner, molten steel is blocked, and steel column formation is avoided, so that unpacking cleaning and transfer operations of castings are simple and convenient.

Description

technical field [0001] The invention relates to the technical field of metallurgical casting equipment, in particular to a runner sealing device for water-cooled die casting. Background technique [0002] When the steel ingot is cast by the water-cooled die casting process, during the pouring process, the molten steel enters the cavity of the casting mold from the sprue opening of the vertical sprue arranged on the chassis, and finally condenses to form a steel ingot. However, when the steel ingot is formed, the molten steel from the tail of the steel ingot to the vertical runner will also be cooled synchronously to form a steel column. The formation of the steel column is not conducive to the unpacking, cleaning and transfer of the casting. Contents of the invention [0003] The purpose of the present invention is to provide a runner sealing device for water-cooled mold casting that can seal the vertical runner and block the molten steel, thereby avoiding the formation of...

Problems solved by technology

However, when the steel ingot is formed, the molten steel from the tail of the steel ingot to the vertical sprue will also be cooled synchronously to form a steel column. The formation of the steel column is not conducive to the unpacking, cleaning and transfer of castings.
