Description

Technical Field

[0001] The utility model relates to the field of spraying devices, in particular to a spraying device for a die-casting mold. Background Art

[0002] During the die-casting process, during continuous spraying, the surface of the mold spraying area is always under a high temperature gradient, and the thermal shock on the surface is very large. Therefore, the large temperature gradient is one of the reasons for damaging the life of the mold and reducing the performance of the casting product. At present, most related die-casting companies generally use water-based release agents to adjust the mold temperature field, but this method has a long preheating time and a long start-up time for the spraying system. In addition, after using this method, the thermal shock on the mold surface still exists and does not meet the requirements of energy saving and environmental protection. Since the die-casting mold is expensive, and the thermal shock damage to the mold is very serious, it indirectly leads to a substantial increase in manufacturing costs.

[0003] According to the patent application number CN201120188053.2, a temperature-controlled spraying device for die-casting release agent spraying is provided, which includes a temperature cycle control unit, a die-casting machine monitoring system, a spraying robot and a release agent supply device; the temperature cycle control unit is connected to the input end of the die-casting machine monitoring system, and the output end of the die-casting machine monitoring system is connected to the release agent supply device; the release agent supply device is connected to the spraying robot. The device can effectively reduce 80% of the mold preheating time, 40% of the spraying start time, and reduce the thermal shock of the mold surface, thereby greatly reducing the number of defective parts, saving energy, and enhancing environmental protection.

[0004] There are still some deficiencies in this patent application. This patent only considers the damage to the mold caused by temperature. The high-speed spraying impact force is also an important cause of damage to the mold. If there are too many impurities in the release agent, it is easy to clog the spraying device and affect work efficiency. Therefore, a spraying device for die-casting molds is needed to solve this problem. Utility Model Content
