Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a cooling water channel mechanism for injection molds. Background Technology

[0002] The cooling water system of an injection mold, commonly known as the "water system," refers to a series of precisely designed and manufactured pipe networks embedded inside the mold core, template, and other components. Its fundamental purpose is to quickly and evenly remove the enormous heat released when molten plastic solidifies within the mold cavity through a circulating cooling medium.

[0003] In the operation of most existing injection molds, the external cooling pipes connected to the moving mold are usually in the form of hoses. With the reciprocating motion of the moving mold, these hoses are forced to be dragged and twisted frequently, which can easily lead to problems such as messy pipe layout and tangling. This situation not only hinders on-site management, but also poses a significant risk that the pipes may be caught in moving parts, causing them to be squeezed and broken or the joints to be damaged, directly threatening production safety and equipment reliability.
