Description

Technical Field

[0001] The utility model relates to the field of die steel processing, in particular to a cooling device for die steel. Background Art

[0002] Mold steel is a steel material used to manufacture injection molds, cold stamping molds, hot forging molds, die-casting molds and other molds. Molds are the main processing tools for mechanical manufacturing, radio instruments, motors, electrical appliances, industrial production, etc. The quality of the mold directly affects the quality of the pressure processing technology, the precision output of the product and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment in addition to reasonable structural design and processing accuracy. During the production process, the mold steel needs to be cooled on the surface after heating before the next process can be carried out.

[0003] According to a cooling device for mold steel disclosed in Chinese patent number CN219063849U, it includes a conveyor and a water tank, a pneumatic telescopic rod is movably provided on the surface of one side of the conveyor, and the upper end of the pneumatic telescopic rod is fixedly connected to an air box, a fixed box is fixedly installed on the left side of one end of the conveyor, and a plurality of nozzles are installed on the surface of the other side of the conveyor, a water pump is fixedly installed on the outside of the water tank, and the water pump is connected to the nozzle through a water guide pipe, a plurality of fans are movably installed inside the fixed box, and an air outlet is opened on one side of the fixed box. In the above patent scheme, the fan and the nozzle are arranged opposite to each other. When the nozzle sprays water onto the heated mold steel, the high temperature will cause the water to evaporate quickly to form steam. Under the blowing action of the fan, a large amount of steam is blown to one side, which not only causes a waste of water resources, but also easily causes workers to be scalded by steam. For this reason, we propose a cooling device for mold steel to solve the above problems. Utility Model Content
