Cooling type die-casting machine charging barrel assembly

Abstract

The invention discloses a cooling type die-casting machine charging barrel assembly. The assembly comprises a charging barrel, a sleeve, a cooling piece, a plurality of heat dissipating plates, a water inlet pipe and a water outlet pipe. A blanking port is formed in one end of the charging barrel. The periphery of the charging barrel is sleeved with the sleeve. An accommodating bin is arranged inthe middle of the sleeve, and an opening of the accommodating bin faces the periphery of the charging barrel. The cooling piece is arranged in a barrel shape, and a water bin is formed in the hollow interior of the cooling piece. The periphery of the charging barrel is sleeved with the cooling piece, and the cooling piece is arranged inside the accommodating bin. The multiple heat dissipating plates are arranged in a ring shape, arranged in the cooling piece in the extending direction of the cooling piece, and provided with a plurality of through holes. The water inlet pipe penetrates throughone end of the sleeve and communicates with the cooling piece. The water outlet pipe penetrates through the other end of the sleeve and communicates with the cooling piece. The height of the horizontal position where water inlet pipe is located is smaller than the height of the horizontal position where the water outlet pipe is located. According to the cooling type die-casting machine charging barrel assembly, the cooling piece has a quite good heat dissipating effect and the quite good heat dissipating efficiency on the charging barrel, and equipment is stable in overall structure, not proneto being damaged and long in service life.

Description

technical field [0001] The invention relates to the field of die-casting machine equipment, in particular to a cooling type die-casting machine cylinder assembly. Background technique [0002] Die-casting machine is a series of industrial casting machines that hydraulically inject molten alloy materials into molds for cooling and forming under pressure, and obtain solid metal castings after mold opening. The pressure is provided by a randomly configured hydraulic system. [0003] When the cold chamber die-casting machine is performing injection die-casting, the barrel needs to be cooled. By cooling the barrel, it can effectively prevent the alloy liquid from adhering to the inner surface of the barrel and avoid damage to the surface of the barrel and the surface of the hammer head. . Generally, the cooling water circulation is set in the head plate for cooling, but the cooling effect is poor, the service life of the barrel and the hammer head is short, and frequent replacem...

AI Technical Summary

Problems solved by technology

Under normal circumstances, it is usually adopted to set up cooling water circulation in the head plate for cooling, but the cooling effect is poor, the service life of the barrel and the hammer head is short, and frequent replacement is required, which affects production and increases costs.
