Description

Technical Field

[0001] The utility model relates to the field of cooling water channels for die-casting moulds, in particular to a cooling water channel mechanism and a die-casting mould thereof. Background Art

[0002] Die-casting molds are usually an important tool commonly used for casting metal parts. During the die-casting process, the die-casting mold can fill liquid or semi-liquid metal into the mold cavity under high pressure and quickly solidify under pressure to obtain castings.

[0003] The die-casting mold usually includes an upper mold and a lower mold. The upper mold and the lower mold are pressed together to die-cast the product. The upper mold usually includes an upper mold body and a mold cavity, and the lower mold usually includes a lower mold body and a mold body. When the die-casting mold is in use, it is usually necessary to cool the upper mold and the lower mold, and a cooling water channel mechanism will be used.

[0004] The cooling water circuit mechanism of the prior art includes a circulation pipe, which is usually installed inside the upper and lower molds, and then uses cooling water to flow inside the circulation pipe, and the cooling water exchanges heat with the upper and lower molds, thereby cooling the upper mold.

[0005] However, when cooling the lower mold, usually only the lower mold body is cooled, and the lower mold body is used to transfer heat to the mold body to cool the mold body. However, this method will cause the end of the mold body to be far away from the lower mold body, resulting in insufficient cooling of the end of the mold body, affecting the cooling effect inside the die-cast product. In addition, the cooling water channel mechanism is not convenient for cooling the end of the mold body, and there are certain limitations. Utility Model Content
