Technical Field

[0001] The utility model relates to the technical field of die-casting machines, in particular to a lubricating mechanism for a die-casting punch of a die-casting machine. Background Art

[0002] A die-casting machine is a machine used for pressure casting. Molten metal is hydraulically injected into a mold using high pressure. After cooling and forming, the mold is opened to produce a solid metal casting. It is widely used in the production and manufacturing of metal parts. During the die-casting process, an internal punch assembly pushes the casting into the mold to form the material. Because this push-in process involves high speed and high pressure, it causes friction and wear on the punch. To reduce the wear and tear of the punch, a lubrication mechanism is required to assist in lubrication of the punch. By using lubricating oil, an oil film can be formed between the punch and the mold, avoiding direct metal contact, thereby reducing wear and extending the service life of the punch and mold.

[0003] However, during the lubrication process of the die-casting punch of the die-casting machine, the lubricating oil liquid can generally only lubricate a single point on the top of the punch. Under the rapid operation of the punch, the lubricating oil liquid cannot reach other parts of the outside of the punch in time, and the lubrication effect is poor. There are deficiencies, and it is not convenient to evenly lubricate multiple points on the outside of the punch.
