DEVICE AND METHOD FOR COOLING AND EXTRACTING INJECTION-MOLDED HOLLOW BODIES

摘要

An injection molding machine for production of parisons (1) of thermoplastic material, comprising a carrying device (2) to remove the parisons from the molds and bring them near to a cooling plate (4) comprising nozzles (5); the cooling plate being able to be operated so that said nozzles enter the parisons (1) which are cooled externally by means of heat exchange with the carrying device and internally by means of heat exchange with the nozzles (5); the nozzles (5) and the carrying device (2) being cooled by means of a cooling fluid circulating on the inside thereof and means (205) being provided to eject the parisons, which are collected by a conveyor belt and carried to a storage unit.
