Abstract

The invention provides an automatic lubricating device for a die-casting die sliding part. The lubricating device comprises a reciprocating piston cylinder, a two-position three-way electromagnetic valve, a high-pressure air cylinder, a pressure reducing valve, an electromagnetic one-way valve, a lubricating grease cylinder, a two-position three-way electromagnetic ball valve, a lubricating greasedistributor and an industrial control box. According to the automatic lubricating device for the die-casting die sliding part, excessive kinetic energy of injection action in the die-casting production process is converted into air internal energy, lubricating grease is pushed to flow to all lubricating points of the die-casting die sliding part, automatic, continuous and quantitative lubricatingmaintenance can be provided for a die-casting die; and the automatic lubricating device is low in energy consumption and high in universality, and can be widely applied to the actual continuous die-casting production process.

Description

technical field [0001] The invention belongs to the technical field of equipment lubrication, and in particular relates to an automatic lubrication device for sliding parts of die-casting molds. Background technique [0002] Die casting (referred to as die casting) process is a high-efficiency, high-efficiency metal forming process with less cutting and no cutting. It is characterized by pressing molten metal into the mold cavity under high speed and high pressure in a very short time. In the actual die-casting production process, the long-term reciprocating motion of the die-casting mold makes the sliding parts of the mold, such as the ejector pin, the slider in the core-pulling mechanism, the slider seat, and the guide bar, easily wear and tear, which affects the molding quality of the die-casting parts and shortens the life of the mold. The service life of the mold will reduce the production efficiency. For the lubricant used in the movement sub-components of die-casting...
