Description

Technical Field

[0001] The utility model belongs to the technical field of mold processing cooling, in particular to a mold processing cooling device. Background Art

[0002] Mold processing plays a vital role in industrial production. It is used in the production and manufacturing processes such as forming, die casting, and injection molding to produce molds with specific shapes and sizes. The basic structure of the mold is usually a group of upper and lower molds. The injection mold is to fill the mold with resin material, and then open the mold to take out the molded resin product; the stamping mold is to place the steel plate between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the mold shape will be obtained or the corresponding waste will be removed.

[0003] In order to shorten the molding cycle, ensure product quality, avoid downtime, prevent mold adhesion, increase mold life and effectively control temperature during mold processing, the mold needs to be cooled to improve overall production efficiency and product quality.

[0004] Existing mold processing cooling devices usually use water cooling pipes to connect with the water channels of the molds, but not all molds are designed with water channels. In molds without water channels, manual spraying of coolant or release agent is generally used to cool the molds, which not only adds unnecessary processes, but also causes uneven cooling effects due to the instability of human operation, thereby affecting the quality of stamping parts and the service life of the molds.
