Abstract

The present invention relates to a slider used for a die and a die thereof. A rolling device is arranged on the body of the slider or the die, thereby, the excellent relative slip between the slider and the die can be realized by means of the rolling device, and the unhealthy tendency of blocking of the die can be avoided.

Description

【Technical field】 [0001] The invention relates to a mold assembly, in particular to a slide block for a mold and a mold. 【Background technique】 [0002] In recent years, with the rapid development of the automobile and household electrical appliance industries, the demand for molds, especially large, precise, complex and long-life molds, is increasing, and the performance requirements for mold standard parts are also getting higher and higher. Among them, the slider is widely used in molds because of its adjustable processing of undercuts or side holes. [0003] However, in the current mold structure, the contact between the slider and other mold components adopts a surface contact method. This contact method has a large frictional resistance, and sometimes even die jamming occurs. 【Content of invention】 [0004] In view of this, it is necessary to provide a slide block and mold for a mold that has small frictional resistance and can be safely removed from the mold.
