Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to injection molds. Background Technology

[0002] With the continuous advancement of science and technology, molds are being used more and more widely. For injection molds, the material inside the mold needs to be cooled to a sufficiently low temperature before it can be removed from the mold without deformation. Therefore, cooling pipes are often installed inside the mold.

[0003] In existing injection molds, extended water nozzles are often used to connect to the side of the mold core to achieve the connection of cooling pipes. However, leakage is prone to occur at the joint of the water nozzle. Because the connection between the extended water nozzle and the mold core is inside the mold, the water leakage at the joint is not visible, and water leakage may occur at the joint, which may lead to rusting of the internal structure of the mold.
