Description

Technical Field

[0001] The utility model belongs to the technical field of metal die-casting equipment, in particular to a nozzle of a lubrication device. Background Art

[0002] In the metal die-casting process, it is usually necessary to heat the workpiece before die-casting. During this process, the structure and surface composition of the workpiece will undergo subtle changes, so corresponding solutions are also needed. For example, if oxide scale is produced on the surface, it needs to be peeled. To avoid cracks in the workpiece during the die-casting process that affect the quality of the finished product, it is necessary to lubricate the surface with ink before die-casting. The above two measures usually require liquid spraying. Although the existing nozzles can complete the work, when the liquid spraying stops, the liquid remaining in the nozzle or the equipment will often leak out. It is difficult to accurately control the amount of liquid spraying in the above two process measures, and it will also cause certain damage to the workpiece. In order to solve this technical problem, we designed a lubrication device nozzle. Utility Model Content
