Abstract

PURPOSE:To make dummy casting unnecessary, and to shorten a preheating time, by pinching a heating plate placed on the PL surface of metallic molds, by the metallic molds, and preheating the metallic molds before starting a casting work, through the heating plate. CONSTITUTION:A heated heating plate 1 is placed on th PL surface of metallic molds, and the heating plate 1 is clamped by a fixed mold liner 2 and a moving mold liner 3 by operating a die casting machine. A shape of the heating plate 1 is formed in reverse similar figures against an uneven shape of a product cavity. As a resut, a degree of adherence of the contact surface of the heating plate 1, and the fixed mold liner 2 and the moving mold liner 3 is increased, the surface of the mold liners 2, 3 absorbs quickly high temperature heat of the heating plate 1, and its surface temperature rises up to about 150-250 deg.C. Subsequently, the heating plate 1 is drawn out by opening a machine moving die plate 12, a releasing agent is applied, and immediately the production is started.
