A first protrusion member 12 is provided on two side surfaces of a fixed mold 1 having a first parting surface 11. Moreover, a second protrusion member 22 is provided on side surfaces of a moving mold 2 including a second parting surface 21 having the same shape and size as the first parting surface 11, that is, two side surfaces placed in positions which are not opposed to the first protrusion member 12 when the fixed mold 1 and the moving mold 2 are closed. Consequently, the fixed mold 1 and the moving mold 2 are positioned by fitting the first protrusion member 12 into the side surface of the moving mold 2 and fitting the second protrusion member 22 into the side surface of the fixed mold 1. Consequently, it is not necessary to provide a guide pin in order to carry out the positioning and a size of a device can be reduced correspondingly. Moreover, it is possible to decrease heat capacities of the fixed mold 1 and the moving mold 2 by the reduction in the size, thereby decreasing consumed power required for a temperature control. |
