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.
Claims26
An injection molding machine clamp assembly configured to clamp a relatively movable platen to a relatively stationary platen, comprising:
- injector structure coupled to the relatively movable platen and configured to actuate a molten material injection structure when the relatively movable platen and the relatively stationary platen are closed;
- and
- ejector structure coupled to the relatively movable platen and configured to actuate a molded article ejection structure when the relatively movable platen and the relatively stationary platen are open.
Molding machine apparatus, comprising:
- an ejector plate configured to be coupled to a moving 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 moving 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.
Molding machine apparatus, comprising:
- a movable clamp column;
- an injector piston disposed at a distal end of the 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.
A method of operating a molding machine, comprising the steps of:
- driving an injector rod through a hole in a moving platen to cause a shooting pot to be discharged when the moving platen is clamped to a fixed platen;
- and
- driving an ejector rod through another hole in the moving platen to cause a molded article to be ejected from a mold part when the moving platen is separated from the fixed platen.
