Abstract
A rotary blow molding machine includes a plurality of mold stations on a rotary carousel. Each mold station includes an elongated support body, such as multiple tie rods, with a first of the mold sections relatively movably disposed on the support body and a second of the mold sections affixed on the support body for movement therewith. An actuator is connected between the first mold section and the support body to move the support body and the second mold section. A synchronizer linkage is connected between the first mold section and the support body to effect concurrent movement of the first mold section in an opposite direction and equal amount to movement of the second mold section.
Claims8
A mold station for a blow molding machine, said mold station comprising:
- (a) elongated, movable support means for supporting a first mold section and a second mold section, said mold sections movable toward and away from each other along a common axis located between said mold sections,
- (b) said first mold section being disposed on the support means such that the first mold section and the support means are relatively movable with respect to one another,
- (c) said second mold section being connected to the support means for movement therewith, said second mold section being connected to the support means by a trunnion extending transverse to said axis,
- (d) actuating means connected between the first mold section and the support means, said actuating means being operable for moving the support means so that the second mold section moves toward the first mold section, a predetermined distance said actuating means being connected to the first mold section and to the support means by respective trunnions extending transverse to said axis, and
- (e) synchronizer linkage means connected between the first mold section and the support means for concurrently moving the first mold section toward the second mold section by a distance equal to said predetermined distance in response to said actuating means, whereby the first mold section and second mold section are clamped together.
