Abstract

The invention discloses a lubricating and cooling system for a die-casting machine injection punch and a lubricating and cooling method. The system comprises the injection punch, a connector, an injection rod, a cooling device, a lubricating device and a PLC (Programmable Logic Controller) arranged on the die-casting machine, wherein the injection punch is fixedly connected with the injection rod through the connector; a spiral oil suction groove is formed in the outer circumferential surface of a punch body of the injection punch; the cooling device and the lubricating device are respectively used for cooling and lubricating the injection punch; the lubricating device can be used for uniformly spraying atomized punch lubricating oil to cover the punch body and store the lubricating oil in the spiral oil suction groove; during the whole injection process, the lubricating oil in the groove can be continuously permeated into a pressure chamber, so as to guarantee supply of the lubricating oil; the cooling device is controlled by the PLC to cool and further can realize automatic cooling water recycle. The lubricating and cooling system disclosed by the invention can lubricate and cool the injection punch, ensures the clearance between the injection punch and the pressure chamber to meet the requirement, and facilitates improvement of the product quality and reduction of the enterprise production cost.

Description

technical field

[0001] The invention relates to the technical field of casting, in particular to a method and device for lubricating and cooling the injection punch of a die-casting machine. Background technique

[0002] At present, aluminum alloy die-casting parts are widely used in automobiles, communications, lighting and other industries, especially in the automotive industry. Many parts are integrally formed by aluminum alloy die-casting, which is an efficient and high-quality production method. In the die casting process of aluminum alloy parts, after the aluminum liquid is injected into the pressure chamber, the aluminum alloy liquid must be injected into the mold cavity through the injection punch under high pressure and high speed, and cooled and solidified to obtain the product we need.

[0003] The injection punch is one of the important parts used to push the aluminum liquid into the pressure chamber and force the aluminum liquid to fill the cavity in the die-cas...
