Abstract

PURPOSE: To obtain a highly accurate pattern free from torsion etc. by using metallic dies having a specified clearance between the upper and lower die guide parts for inside forming that requires high dimensional accuracy, and using rubber dies for outside forming which is high in decorative element.
CONSTITUTION: In manufacturing a watch case by a lost wax casting method, inside forming of wax pattern of the body is made by metallic upper die 8 and lower die 9, and outside forming that has decorative part is made by raw rubber. The upper die 8 and lower die 9 are positioned by guide pins 10 fixed to the lower die 9. The dies and the diameter of the pins are so designed that the upper and lower dies can be separated freely. The clearance between the upper and lower guides parts is made to 1/100mm. Grooves 8a are made on the upper die 8 and grooves 9a are made on the lower die 9 at several places to prevent shifting between the raw rubber ad metallic dies.
