Description

Technical Field

[0001] The utility model relates to the technical field of steel plate stamping, and more particularly to a cleaning device for injection mold production. Background Art

[0002] An injection mold is a tool used to produce plastic products through injection molding. The injection mold can be recycled, but the mold needs to be cleaned after injection molding to avoid residues from the previous injection molding in the mold, which may cause failure in the next injection molding.

[0003] When cleaning the injection mold currently, the injection mold is placed in a pool of water and then manually cleaned. During the cleaning process, people need to move the injection mold back and forth, which is time-consuming and labor-intensive. After cleaning multiple injection molds, the water used to clean the injection molds will contain more impurities. When the injection molds are taken out of the water, some impurities will be adsorbed on the injection molds, resulting in poor cleaning effect of the injection molds. In addition, after cleaning the injection molds, there will be more water on the surface of the injection molds. The existing injection mold cleaning device lacks corresponding drying equipment, which is inconvenient for drying the cleaned injection molds, reducing its practicality. Utility Model Content
