APPARATUS AND METHOD FOR FABRICATING CONTAINERS

摘要

An apparatus for fabricating containers. The apparatus including a plurality of mold segments, an injection cylinder, a closure cylinder and a motor cylinder. The injection cylinder defining a mold cavity substantially in the form of a container and accommodating a substantially tubular preform having a preform cavity in communication with an open end. The injection head establishes fluid communication with the preform and the injection cylinder is in fluid communication with the injection head and configured to inject a volume of liquid into the preform The closure cylinder is configured to exert a force on at least one of the mold segments to maintain them in a closed disposition. The motor cylinder is configured to drive the injection cylinder and being itself concurrently driven with the closure cylinder by a single pressure source.

1. An apparatus for fabricating containers, comprising:
a plurality of mold segments, said plurality of mold segments defining a mold cavity substantially in the form of a container and configured to accommodate a substantially tubular preform having a preform cavity communicating with an open end; an injection head, said injection head configured to cooperate with said open end of said preform and establish fluid communication therewith; an injection cylinder, said injection cylinder comprising a chamber with a piston mobile therein and being disposed in fluid communication with said injection head, and further configured to inject a volume of liquid into said preform when said piston is advanced within said chamber; a closure cylinder (125), said closure cylinder (125) being configured to exert a force on at least one of the mold segments so as to maintain said mold segments in a closed disposition; a motor cylinder comprising a piston, the piston of said motor cylinder driving said piston of said injection cylinder, the motor cylinder and closure cylinder being concurrently driven by a single pressure source.
