PURPOSE: To eliminate an alteration of a mold in a waving unit and hence a pausing time of an overall mold by advancing a mold cavity from an upstream position along a linear feeding passage, and bringing it into close contact with a second mold cavity supplied with molten plastic material prior to supply to the mold cavity. CONSTITUTION: A linear motion to front or rear of mold carriages M-1, M-2 at substantially linear feeding passage is conducted by substantially equal pair of first actuators. The first actuator is coupled to the carriage M1 along its top side, while the first actuator is supported at its bottom side, i.e., along a base side in the case of the carriage M-2. Bracket units 38 to the blocks M-1, M-2 are coupled to a drive rack 60. This rack is engaged with a pinion driven by a shaft unit 25 finished at the gears 48, 50. |
