Abstract
What is described is a blow-molding machine for plastic containers, comprising a plurality of platens for supporting blow mold halves, wherein at least two of the platens are in the form of movable multi-carriers for simultaneously supporting at least two blow mold halves which are assigned to different blow-molding cavities. Since the multi-carriers are driven in such a manner that at least one of the blow-molding cavities can be opened and at the same time at least one other of the blow-molding cavities can be closed by means of a continuous movement of the multi-carriers, acceleration and deceleration ramps can be reduced upon opening and closing and it is possible to gain process time for the blow molding.
Claims16
A blow-molding machine for plastic containers with a plurality of mold carriers for carrying blow mold halves, comprising at least two of said mold carriers designed as movable multi-carriers for simultaneously carrying at least two blow mold halves that are associated to different blow mold cavities,
- said multi-carriers being drivable such that at least one of said blow mold cavities can be opened with a continuous motion of said multi-carriers and simultaneously at least one other of said blow mold cavities can be closed,
- where at least two multi-carriers are provided that are movable independently from one another.
A blow-molding machine for plastic containers with a plurality of mold carriers for carrying blow mold halves, comprising at least two of said mold carriers designed as movable multi-carriers for simultaneously carrying at least two blow mold halves that are associated to different blow mold cavities,
- said multi-carriers being drivable such that at least one of said blow mold cavities can be opened with a continuous motion of said multi-carriers and simultaneously at least one other of said blow mold cavities can be closed, and
- a transfer device on which double grippers for gripping a preform and a blow-molded container are provided.
A blow-molding machine for plastic containers with a plurality of mold carriers for carrying blow mold halves, comprising at least two of said mold carriers designed as movable multi-carriers for simultaneously carrying at least two blow mold halves that are associated to different blow mold cavities,
- said multi-carriers being drivable such that at least one of said blow mold cavities can be opened with a continuous motion of said multi-carriers and simultaneously at least one other of said blow mold cavities can be closed,
- where said blow mold halves have parting planes corresponding to each other, on each of which two blow mold halves can be guided to one another, and said blow mold halves are each arranged on said multi-carriers in an unchanged position relative to each other, where, parting planes of said same multi-carrier include an angle (φ) with each other unequal to zero.
