Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with high heat dissipation. Background Art

[0002] Most of the injection molds currently used in the market have poor heat dissipation effects, so that the injection molds need a long time to cool before demoulding. Therefore, the existing Chinese patent with authorization announcement number CN215472707U discloses a high heat dissipation injection mold, which relates to the technical field of injection molds. The utility model includes an upper mold body, an upper positioning plate is fixedly arranged on the front side of the upper mold body, a liquid inlet end is provided on the top of the upper mold body, an injection end is provided at one end of the upper mold body, an upper injection cavity is provided on the inner side of the upper mold body, an upper heat conduction plate is provided on the top of the upper injection cavity, an upper corrugated cooling cavity is provided on the top of the upper heat conduction plate, positioning rods are provided on both sides of the upper injection cavity, and a rubber pad is provided at the bottom of the positioning rod. The utility model is a high heat dissipation injection mold, which injects coolant into the upper corrugated cooling cavity and the lower corrugated cooling cavity through two groups of liquid inlet ends, so that the injection mold can dissipate heat while also increasing the contact area between the injection liquid and the coolant, further improving the heat dissipation degree of the injection mold, and effectively reducing the cooling time of the injection mold.

[0003] However, in actual application, the above mold still has the following problems: the mold and the product are cooled by injecting water into the upper corrugated cooling cavity and the lower corrugated cooling cavity. This cooling method not only wastes water and has poor practicality, but also easily leads to a situation where the water temperature near the liquid inlet end is low, while the water temperature in other places in the corrugated cooling cavity is high. As a result, the product shrinks differently in different parts due to uneven cooling during the cooling process, causing deformation of the injection molded parts and affecting the quality of the injection molded parts. Utility Model Content

[0004] The purpose of the utility model is to provide an injection mold with high heat dissipation in view of the above-mentioned deficiencies, which can not only avoid the waste of water resources and have better practicality, but also can evenly cool the injection molded parts, avoid the deformation of the injection molded parts caused by uneven cooling, and improve the quality of the injection molded parts.

[0007] Furthermore, the mold body includes a fixed mold, a movable mold arranged above the fixed mold, and a mold closing electric cylinder used to drive the movable mold to approach or move away from the fixed mold.
