PROBLEM TO BE SOLVED: To provide rotary type gate cutting equipment for preforms wherein the preforms in a plurality to be molded, cooled and discharged in each cycle are received in a state wherein a disposition pattern of a cavity and a core disposed in a mold is maintained, and operations of cooling, gate cutting and delivery are conducted consecutively with the attitude of the preforms maintained. SOLUTION: A holding means 3 of preforms is made a rotary body (holding frame 13) rotating around the axis of rotation so that the preforms in a plurality disposed at prescribed intervals and held and discharged be received in a first station and cooled in a second station, that gate cutting be conducted in a third station and that delivery to a subsequent process be conducted in a fourth station. Holding bars 14 for holding the preforms are provided on each side of the rotary body and rotated at an angle of 90 deg. for each cycle and thereby the operations at the positions of the separate stations are conducted consecutively. |
