Description

Technical Field

[0001] The present application relates to the field of double-axis holes of die-casting molds, and in particular to a double-axis hole cooling system structure of a die-casting mold. Background Art

[0002] The double-axis hole of the die-casting mold is a specific cooling system structure designed to improve the cooling efficiency and speed of the die-casting mold. This structure involves a mold with a first axis hole, a second axis hole and a guide channel in the bottom wall. The first axis hole and the second axis hole are symmetrically arranged on both sides of the guide channel, and are respectively connected to the water inlet and water outlet of the guide channel. Through this design, the coolant can be connected to the inside of the mold through the first axis hole. After the molten liquid is injected, the die-casting machine is die-cast. After molding, the coolant is injected through the first axis hole, and the coolant quickly cools the molded shell through the guide channel. After cooling, the coolant is discharged through the second axis hole. This structure directly cools the inside of the mold and has the characteristics of fast cooling speed and high efficiency.

[0003] Regarding the above-mentioned related technologies, the inventors believe that after a period of use, the conventional die-casting mold's double-axis hole is easily affected by the high temperature of the coolant, which can cause some impurities in the coolant to adhere to the inner wall of the cooling tube. The solidified coolant causes blockage of the inner wall of the cooling tube, and the conventional cooling tube is difficult to disassemble, resulting in the cooling tube being unable to play a heat dissipation effect after being blocked, affecting the cooling effect of the die-casting mold.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
