Die-casting head plate

Abstract

The invention relates to the technology in the field of die-casting machines, in particular to a die-casting machine head plate, which includes a head plate body, and a first cooling cavity, a second cooling cavity, a third cooling cavity and a fourth cooling cavity are formed by casting in the head plate body. The cavity, the first channel, the second channel and the third channel cooperate with the first channel to communicate between the first cooling chamber and the second cooling chamber, the second channel to communicate between the second cooling chamber and the third cooling chamber, and the third channel Compared with the prior art, the die-casting machine head plate of the present invention forms a large-volume cooling channel, so as to connect the third cooling cavity and the fourth cooling cavity, and use each pressing plate to seal and cover the corresponding casting forming hole. The machining of deep holes is avoided, the efficiency is higher, various processing problems will not occur, and the contact area of ​​the cooling water is increased, thereby greatly improving the cooling efficiency.

Description

technical field [0001] The invention relates to the technology in the field of die-casting machines, in particular to a head plate of a die-casting machine. Background technique [0002] The die-casting machine is a series of industrial casting machines that hydraulically inject molten metal into the mold under pressure to cool and form it, and obtain solid metal castings after the mold is opened. It was originally used for die-casting characters. With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, and starting from energy saving and saving raw materials, die-casting technology has achieved extremely rapid development. [0003] The die-casting machine head plate works in a high-temperature environment. In order to improve the life of the template, it needs to be cooled by water. The current cooling channel is generally processed by drilling, which n...
