<P>PROBLEM TO BE SOLVED: To judge the depth of a bottomed groove by a simple method in a molding technique for molding matter made of a synthetic resin having the bottomed groove. <P>SOLUTION: A pressure member 20 driven by a cylinder 28 is housed in the slide hole 16, which is provided on the fixed mold 12 of a mold 10, in a slidable manner, and a groove molding member 22, which is movable along the guide groove 141 bored in the fixed mold 12, and a moving member 24 movable along the communication hole 142 bored in the fixed mold 12 are erected on the pressure member 20. After a molten synthetic resin is sealed in a cavity 18, the groove molding member 22 is protruded into the synthetic resin by driving the cylinder 28 to form the bottomed groove 76 becoming a breaking part 74 and it is observed whether the projection formed by a moving member 24, of which the vertical part 242 is set so as to become flush with the inner surface 182 of the cavity 18 when the groove molding member 22 protrudes into the cavity 18 by normal dimension, is present in a groove depth confirming part 78 to judge the depth of the bottomed groove 76. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
