PURPOSE: To make it possible to open and close respective segmental dies from the timing of these dies by freely slidably housing the four segmental dies into the sliding passage of a moving middle die and turnably linking and coupling the respective segmental dies and the moving middle die by means of arms. CONSTITUTION: The first and second segmental dies 15a, 15b are parted from the molded goods in a cavity at the point of the time when the solidification of melt ends. A first block body 16 disposed at the center of the moving middle die moves to a die opening direction when a first cylinder 21 operates to move the upper, middle and lower moving dies in a direction where these dies part from a stationary die. Second and third block bodies 17a, 17b are guided by guide pins 14 and move in the die opening direction while parting from the first block body 16. The third and fourth segmental dies 15c, 15d slide while leaving the molded goods in the cavity of the movable upper and lower dies along the sliding passage formed in the first block 16 via the right and left arms 18a, 18b connected to the second and third block bodies 17a, 17b according to the parting of the second and third block bodies 17a, 17b from the first block body 16. |
