PURPOSE: To obtain a molded product free from thickness irregularity or voids by reactive injection molding without requiring a conventional large-sized tiltable press machine. CONSTITUTION: A mold 1 for reactive injection molding consists of a pair of molds wherein a cavity 13 molding a molded product is formed between the molding surfaces of the molds at the time of mold clamping and has the runner 14 communicating with the cavity 13. In a mold clamping state, the parts having, the molding surfaces forming the cavity of the molds are made freely revolvable with respect to the mold main body and the revolving parts 112, 122 are made freely revolvable so that the cavity 13 is inclined with respect to a horizontal surface in such a state that the region provided with the runner 13 is turned downwardly by a rack/pinion mechanism. |
