Abstract
A blow mold clamping apparatus and a blow molding system are disclosed.
Claims20
A mold clamping apparatus for opening and closing a pair of blow molds, the mold clamping apparatus comprising:
- a first inner platen coupled to a first outer platen so as to be movable therewith;
- a second inner platen coupled to a second outer platen so as to be movable therewith;
- and
- an actuator coupled between the first inner platen and the second inner platen for opening and closing a first mold clamp defined between opposing sides of the first inner platen and the second outer platen while simultaneously opening and closing a second mold clamp defined between opposing sides of the second inner platen and the first outer platen,
- wherein the actuator includes a body, a drive shaft coupled to the body for rotation about a drive shaft axis that is fixed relative to the body, and a crank coupled with the drive shaft for rotation by the drive shaft about the drive shaft axis to open and close the first mold clamp and the second mold clamp.

A blow molding system comprising:
- an extruder having an extruder centerline;
- and
- a blow mold clamping assembly having a clamping assembly centerline, and a first mold clamp having a first mold clamp centerline located on a one side of the clamping assembly centerline and a second mold clamp having a second mold clamp centerline located on the opposite side of the clamping apparatus centerline, the blow mold clamping assembly positioned relative to the extruder such that the clamping assembly centerline is parallel with the extruder centerline.
A blow molding system comprising:
- an extruder having an extruder centerline;
- and
- a blow mold clamping assembly having a clamping assembly centerline, and a first mold clamp having a first mold clamp centerline located on a one side of the clamping assembly centerline and a second mold clamp having a second mold clamp centerline located on the opposite side of the clamping apparatus centerline,
- wherein the extruder is positioned entirely above the blow mold clamp assembly.
