Problems solved by technology

For cold chamber die-casting machines, the barrel needs to be cooled during injection die-casting. 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 hammer head. On the surface, in order to prevent the above problems from happening, it is usually adopted to set up a cooling water cycle in the head plate for cooling. There is a certain distance between the cooling water cycle and the barrel, which is an indirect cooling method. The cooling effect of this method is poor, and some If cooling is not carried out, the life of the barrel and hammer head is short, and they need to be replaced frequently, which affects production and increases costs.

Abstract

The invention provides a die casting machine charging barrel good in cooling effect. The die casting machine comprises a charging barrel body and a lining. The lining is sleeved with the charging barrel body. A discharging port is formed in one end of the charging barrel body. The charging barrel body is sleeved with a cooling sleeve. A first annular groove, a second annular groove, a third annular groove...an nth annular groove are sequentially formed in the part, in contact with the cooling sleeve, of the charging barrel body from the end close to the discharging port to the end far away from the discharging port. The cooling sleeve is internally provided with a plurality of cooling medium circulation channels arranged in the axial direction of the cooling sleeve. The cooling sleeve is provided with a plurality of first cooling medium inlets and a plurality of first cooling medium outlets. The first annular groove, the second annular groove, the third annular groove...the nth annular groove communicate with each cooling medium circulation channel. According to the die casting machine charging barrel, heat on the charging barrel body can be effectively brought away, alloy material liquid can be effectively prevented from adhering to the charging barrel body, heat of the alloy material liquid can be prevented from being transmitted to a head plate, the head plate is effectively prevented from being fractured, and the production cost of the die casting machine is reduced.

Description

technical field [0001] The invention relates to the technical field of die-casting machine barrels, in particular to a die-casting machine barrel with good cooling effect. Background technique [0002] Die-casting machines are 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. They are usually divided into two categories: hot-press chamber die-casting machines and cold-press chamber die-casting machines. , The pressure is provided by the randomly configured hydraulic system. For cold chamber die-casting machines, the cylinder needs to be cooled during injection die-casting. By cooling the cylinder, it can effectively prevent the alloy liquid from adhering to the inner surface of the cylinder, and avoid damage to the surface of the cylinder and the hammer head. On the surface, in order to prevent the above problems from happening, it is...
