Abstract
A non-hydraulic injection blow molding machine for making hollow plastic articles. The machine has a parison mold having top and bottom portions for injecting a parison onto each of a plurality of core rods, and a blow mold having top and bottom portions for blowing the parisons into hollow work pieces. The articles are removed from the core rods at an eject station. The core rods are mounted on a turret. The turret rotates to advance the core rods from the parison mold to the blow mold, and from the blow mold to the eject station. The machine has a rotating crank shaft. A translating mechanism translates the rotation of the crank shaft to a vertical reciprocating motion. A clamp beam is connected to the translating mechanism and is actuated by rotation of the crank shaft to move between raised and lowered positions which are separated by a fixed stroke. A non-hydraulic actuating mechanism, which may be a pneumatic mechanism, is connected to the clamp beam for positioning the top portion of each of the parison and blow molds relative to the clamp beam, so that the distance between the top and bottom portions of each respective mold is less than the stroke while the clamp beam is in the raised position. The pneumatic clamping pressure is applied to each of the parison and blow molds when the clamp beam is actuated to the lowered position.
