AI Technical Summary
Technical Problem
In existing technologies, frictional heat and vibration during the ejection process cause frictional wear on the guide rail and base, leading to structural failure.
Method used
Design a layered slider device. The slider includes a lubrication layer, a functional layer and a toughening layer. The lubrication layer has through holes and is filled with lubricating material, which flows into the contact surface between the slider and the guide rail through the through holes to reduce frictional resistance.
Benefits of technology
It effectively reduces the frictional resistance between the slider and the guide rail, extends the service life of the guide rail, and ensures repeated use.

Abstract
This invention provides a guide rail slider device, including a guide rail and a slider, with the slider sliding on the guide rail in cooperation with it. The contact surface between the slider and the guide rail is arc-shaped. From the contact surface with the guide rail inwards, the slider sequentially includes a slider lubrication layer, a slider functional layer, and a slider toughening layer. The slider lubrication layer has several through holes, and the slider functional layer has a sandwich structure with a honeycomb structure, filled with lubricating material. The honeycomb structure has circular holes corresponding to the through holes, through which the lubricating material flows into the through holes and then flows to the contact surface between the slider lubrication layer and the guide rail. By designing the slider in layers and incorporating lubricating material within them, this invention reduces the frictional resistance between the slider and the guide rail and increases the number of uses for the slider and the guide rail during the extrusion process.
