Description

Technical Field

[0002] A die-casting machine injects molten metal into a mold under pressure, where it cools and forms. Once the mold is opened, a solid metal casting is obtained. During the die-casting process, the surfaces of the die-casting punch and the feed chamber are subjected to the high pressure, high speed, and high temperature of the hydraulically-pressurized metal. To ensure proper function of the die-casting punch, lubrication of the die cavity surface or the die-casting punch is necessary.

[0003] The utility model patent with application number 202221849529.7 discloses a lubrication mechanism for the die-casting punch of a die-casting machine, including a die-casting machine, the die-casting machine is provided with a feeding chamber with an upward opening and a die-casting punch arranged in the feeding chamber, the die-casting machine is also provided with a lubrication mechanism for lubricating the die-casting punch, the lubrication mechanism includes a storage component, a discharge component and a feed pipe, graphite particles are provided in the storage component, the discharge component is used to transport the graphite particles in the storage component to the die-casting punch through the feed pipe, the discharge component transports the graphite particles to the discharge component through the feed pipe, the graphite particles lubricate the die-casting punch through the discharge component, thereby reducing the work intensity of the staff, improving the lubrication effect of the die-casting punch, and reducing the loss of the die-casting punch.

[0004] However, during operation, since the opening of the feeding chamber faces upward, impurities and dust in the air will enter the feeding chamber, causing the friction between the inner wall of the feeding chamber and the die-casting punch to increase, affecting the normal movement of the die-casting punch.

[0005] Therefore, a die-casting punch lubrication mechanism for a die-casting machine is proposed to solve some problems existing in the above-mentioned prior art. Utility Model Content

When the die-casting machine is not working, the barrel is in a sealed state, effectively preventing impurities and dust in the air from entering the feed chamber. When the die-casting machine is working, when the magnetic plate at the outer end of the rotating drive rod moves to the adapted position, the isolation plate will be pushed out of the barrel under the action of the magnetic force, so that the barrel is in an open state, so that graphite particles can normally enter the feed chamber, thereby ensuring the normal movement of the die-casting punch.
