Die-casting core puller

Abstract

The invention relates to the field of die-casting molds, and aims to provide a core-pulling slider of a die-casting mold. A die-casting mold core-pulling slider, including a slider body; the die-casting mold core-pulling slider also includes: an exhaust slider, an exhaust slider guide assembly; the front end of the slider body is provided with a The matching hole of the exhaust slider; one side of the exhaust slider is provided with a rear exhaust groove and a front exhaust groove whose rear end is connected with the rear exhaust groove; the front exhaust groove is connected with the front end of the exhaust slider; The depth of the exhaust groove is smaller than the depth of the rear exhaust groove; an exhaust channel communicating with the rear exhaust groove is arranged on the outside of the exhaust slider. The core-pulling slider of the die-casting mold assists the gas in the cavity of the die-casting mold to exhaust fully, so that the die-casting part is not easy to generate pores, and is beneficial to the overall demolding of the die-casting mold.

Description

technical field [0001] The invention relates to the field of die-casting molds, in particular to a core-pulling slider of a die-casting mold. Background technique [0002] During die-casting, it is necessary to discharge the gas in the die-casting mold cavity to improve the quality of the die-casting parts; the exhaust structure of the die-casting mold can be understood from an improved exhaust structure of the die-casting mold disclosed in the utility model of Chinese patent application number: CN201120006506.5; Easy demoulding Many die-casting molds have core-pulling sliders; the structure of core-pulling sliders can be understood from a die-casting mold slider mechanism disclosed in the utility model of Chinese patent application number: CN201420167066.5; the exhaust of traditional die-casting molds The structure exists to be equipped with a core-pulling slider, especially when the product is relatively complex and easy to form air-entrapped die-casting molds during die-c...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the existence of the exhaust structure of the current die-casting mold for the core-pulling slider, especially when the product is more complicated and easy to form air-entrapped die-casting molds during die-casting, the gas in the die-casting mold cavity will Insufficient exhaust, die-casting parts are prone to lack of pores, and provide a die-casting mold core-pulling slider that assists the gas in the die-casting mold cavity to fully exhaust, so that the die-casting parts are not easy to produce pores
