Filed: 2007-02-02
Abstract: <P>PROBLEM TO BE SOLVED: To provide a casting die which can suppress the generation of a gall due to the tilt and thermal deformation of a slide insert, and can largely contribute to the improvement of the productivity and the reduction of a manufacturing cost.  <P>SOLUTION: The slide insert 4, which is one of die elements for forming a cavity 6, is divided into an insert body 10 and a partial insert 11.

The partial insert 11 having relatively large forming projections 12 is released from a mold preceding the insert body 10. Therefore, the partial insert 11 can be drawn out straight even when the forming projections 12 having large releasing resistance are located in offset positions or the insert body 10 is thermally deformed. As a result, the generation of the gall on the product can be suppressed.  <P>COPYRIGHT: (C)2008,JPO&INPIT
