Abstract

PURPOSE: To manufacture a combustible pattern closely coincident with the original pattern in a short finishing time, by packing a mixture of expanded synthetic resin, bonding medium, and curing agent on the synthetic resin pasted to a one side pattern, by sticking ribs to the upper surface, then by releasing the pattern.
CONSTITUTION: After a molding box 2 of prescribed height (h) is mounted on the upper surface of a one face original pattern 1 on the die side, a synthetic resin sheet 3 is sticked through parting agent to the internal peripheral surface, in addition, parting agent is painted on said synthetic resin sheet 3, and lumps or pieces 4 of expanded styrene are arranged on the sheet 3 with intervals, and the spaces made by the lumps of styrene is filled with a mixture of particles of expanded styrene etc., bonding agent, and curing agent which cures at ordinary temp., then the upper surface is made smooth. To the smooth surface is sticked a thin plate of expanded synthetic resin 6, in addition, to the upper surface of which is sticked ribs 7 made of expanded synthetic resin. The completely solidified expanded synthetic resin pattern P' is removed from the pattern 1. Subsequently expanded synthetic resin plates 8 and 81 having thickness h2 corresponding to finishing stock is sticked to the pattern surface P', which has been in contact with the pattern 1, of a pattern P' removed from the sheet 3. Hereby punch side pattern P having a prescribed dimension H, or prescribed dimensions H and W, is manufactured.
