Abstract
Injection molding machine apparatus and method with moving platen injection and ejection actuation is provided for an injection molding machine clamp assembly configured to clamp a relatively movable platen to a relatively stationary platen. Injector structure is coupled to the relatively movable platen and is configured to actuate a molten material injection structure when the relatively movable platen and the relatively stationary platen are closed. Ejector structure is coupled to the relatively movable platen and is configured to actuate a molded article ejection structure when the relatively movable platen and the relatively stationary platen are open.
Claims16
A molding machine apparatus, comprising:
- a stationary platen;
- a movable platen;
- a mold for producing a molded part having multilayered walls, the mold being mounted between the stationary platen and the movable platen;
- a first injection unit having a first hot runner manifold being coupled with the mold;
- a second injection unit having a second hot runner manifold being coupled with the mold;
- an injection molding machine clamp assembly being configured to clamp the movable platen to the stationary platen, the injection molding machine clamp assembly including:
- an injector structure being coupled to the movable platen and configured to actuate a molten material injection structure when the movable platen and the stationary platen are closed, the molten material injection structure being coupled with the second hot runner manifold;
- and
- an ejector structure being coupled to the movable platen and being configured to actuate a molded article ejection structure when the movable platen and the stationary platen are open.
A molding machine apparatus, comprising:
- an ejector plate configured to be coupled to a movable platen, and configured to be movable with respect thereto;
- an ejector rod configured to be moved by said ejector plate, and configured to remove a molded article from an mold part;
- an injector plate configured to be coupled to the movable platen, and configured to be movable with respect thereto, said injector plate being configured to be independently movable with respect to said ejector plate, and configured to be movable in the same direction as said ejector plate;
- and
- an injector rod configured to be moved by said injector plate, and configured to actuate a shooting pot piston;
- an ejector cylinder;
- an ejector piston disposed in said ejector cylinder and configured to actuate said ejector rod;
- an ejector cylinder;
- and
- an injector piston disposed in said injector cylinder and configured to actuate said injector rod.
A molding machine apparatus, comprising:
- a movable clamp column;
- an injector piston disposed at a distal end of the movable clamp column and configured to be movable with respect thereto and in the same direction;
- and
- an ejector piston disposed at a distal end of the injector piston and configured to be movable with respect thereto and in the same direction.
