Injection molding machine for manufacturing preforms for plastic bottles, has re-cooling device covering cavities of molding tools at cooling stations, where distances of support pins at removing and transfer grippers are changed

摘要

The machine has two molding tools (8, 9) with cavities, and a removing gripper (11) and/or a transfer gripper (12) comprising support pins corresponding to the cavities of the molding tools. A re-cooling device (19) covers integral cavities of the molding tools at cooling stations. Distances of the support pins at the removing and transfer grippers are changed in two directions. A drive device changes the distances of the support pins. The drive device is electrically, hydraulically, pneumatically or mechanically actuated.
