PURPOSE:To simplify replacing work by fitting a telescopic mold molding a partial surface only partially different in shape from each other in the inside mold clamped to an outside mold from a parting surface side at the part opposed to the molded product opening part of a combined mold to hold the same between the inside and outside molds. CONSTITUTION:A split mold 2 is externally fitted to the smallest split mold 1 to be clamped thereto on the side of a parting surface 7 by bolts 5 and a split mold 3 is externally fitted to the mold 2 to be clamped thereto by bolts 6. The parting surface 7 necessary of or molding is formed by the split molds 1, 2, 3. In order to mold a molded product whose surface shape is different only in a grade display part 13 like a cassette half body 11, a telescopic mold 15 molding a display part 13 is fitted in the molds 1, 2 to be held therebetween so as not to be drawn out. Therefore, at the time of the replacement of the telescopic mold 15, the clamping of the molds 1, 2 due to the bolts 5 is easily released on the side of the parting surface 7 and the telescopic mold 15 can be easily replaced. |
