Description

Technical Field

[0001] This utility model relates to a tool, or more precisely, a device for facilitating the observation of cooling water return in a die-casting machine. Background Technology

[0002] During the casting process, the operating temperature of the die-casting machine can reach as high as 200℃. Different aluminum alloys have different melting points and set points, but most exceed 200℃. This generates very high temperatures, and if these temperatures are not dissipated in time, it can easily lead to a decline in the quality of the die-casting machine and the castings, or even malfunctions. Therefore, cooling water is necessary for heat dissipation. Simultaneously, during the operation of the die-casting machine, various components such as pistons and guide sleeves need to constantly contact and separate from the mold. Due to the high temperature of the molten metal, failure to dissipate heat in time can cause deformation of components such as pistons and guide sleeves, significantly affecting the quality of the die-cast parts. Furthermore, if certain parts of the die-casting machine are exposed to high temperatures for extended periods, oxidation and wear can occur, impacting the lifespan of the die-casting machine.

[0003] The existing method for observing cooling water return is to disconnect the return water pipe. The die-casting machine is stopped, the return water pipe is disconnected, and the ignition cooler switch is adjusted to check if water flows out. However, this method has certain advantages and disadvantages. While it is widely applicable and low-cost, it requires the equipment to be stopped, impacting production and failing to detect problems during production, thus compromising product quality.
