Abstract

PURPOSE: To prevent the camber of a liner and eliminate the formation of any flash by making the liner adjustable by means of a main mold.
CONSTITUTION: A neceesary void amount is assured in the bottom part 12 of the recess 2 of a main mold by determining the thickness of a spacer 10 from the relation of a liner 13 and a cavity, and the liner 13 is held by means of a pulling means 16 through the hole 15 pierced in the lower part of the main mold to end assembling at room temp. Next, when the mold is-heated up to about the pouring temp. of molten metal, the liner 13 expands and therefore the pulling means 16 is tightened to assure the flat state of the liner 13. Molten metal is then poured and the joint surface is made uniform by adjusting the male and female molds respectively. As a result, the mold registration is uniformalized always at the same surface in a movable state. The above-mentioned process prevents the camber of the liner, eliminates molten metal leakage and obviates the formation of any flash. In addition, the dimensional accuracy of the products may be improved.
