Slide mechanism for squeeze casting moulds

Abstract

The utility model discloses a slider mechanism of squeeze casting mould, including slider core and the slider seat of connection setting in the rear end of slider core, the rear end of slider seat is connected with a drive oil cylinder, the characteristics are that the slider core is in the position of corresponding product's thick wall forming area and can be set up locally extruding pin of movable in front and back, and locally extruding pin is driven through a locally extruding oil cylinder, and locally extruding oil cylinder sets up in the rear end of slider seat. Advantages are that locally extruding pin driven by independent oil cylinder is set up in the position of corresponding product's thick wall forming area in the slider core, and the thick wall forming area of product is directly aimed at through the locally extruding pin, and in the solidification process of casting, the pressure is continuously exerted through the locally extruding pin, and the molten metal is forced to compensate, so the solidification shrinkage is compensated from the root, and the shrinkage cavity rate is reduced significantly, and the good product rate is effectively improved.
