Water-cooled mold for casting aluminum alloy wheel

Abstract

The present application provides a water-cooled mold for casting an aluminum alloy wheel, which is composed of a top mold, a side mold and a bottom mold, wherein a side mold insert is included between the side mold and the bottom mold, the inner surface of the side mold insert faces a cavity, and the upper surface and the lower surface are matched with the side mold frame respectively; the side mold insert is made of copper; the matching surface between the side mold insert and the side mold has a contact matching surface having a length of 10-15 mm at the edges of the inner ring and the outer ring respectively. And the side mold insert and the side mold form a gap which is 0.05-0.20 mm between the contact matching surfaces.

What is claimed is: 
     
         1 . A water-cooled mold for casting an aluminum alloy wheel, comprising a top mold, a side mold and a bottom mold, wherein a side mold insert is arranged between the side mold and the bottom mold, the inner surface of the side mold insert faces a cavity, and the upper surface and the lower surface are matched with the side mold frame respectively; the side mold insert is made of copper; the matching surface between the side mold insert and the side mold has a contact matching surface having a length of 10-15 mm at the edges of the inner ring and the outer ring respectively, and a gap of 0.05-0.20 mm is formed between the side mold insert and the side mold. 
     
     
         2 . The water-cooled mold according to  claim 1 , wherein the matching surface between the side mold insert and the side mold has a contact matching surface having a length of 12 mm at the edges of the inner ring and the outer ring of the matching surface respectively, and a gap of 0.10 mm is formed between the side mold insert and the side mold, and the gap is formed also between the contact matching surfaces. 
     
     
         3 . The water-cooled mold according to  claim 1 , wherein in the water-cooled mold, a cooling water channel of the bottom mold is located on the outer side of the bottom mold.
