PROBLEM TO BE SOLVED: To provide a self-propelled carriage used for foam molding equipment with the high degree of freedom of layout change. SOLUTION: The carriage 70 carrying a mold 80, a hot water tank 78, a battery 71, an air tank 9 and the like circulates through lines 1-6, and in each one round, a molding is molded. In an explosion-proof zone 10, urethane stock solution is supplied to the mold 80. The carriage 70 travels through one of the lines 3, 3a, 3b after traveling the lines 1 and 2. During these processes, the mold 80 is heated by the hot water, and foaming and curing reactions of urethane proceed. An upper mold 82 is released by a lid opening machine 31, and the molding is released from a lower mold 81 in a mold releasing zone 32. In waiting in a waiting zone 60, replacement of the hot water, air supply to the air tank 79, and charging of the battery 71 are carried out. COPYRIGHT: (C)2009,JPO&INPIT |
