US Patent:

50339559, Jul 23, 1991

Filed:

Oct 10, 1990

Appl. No.:

7/597090

Inventors:

Harold Faig - Cincinnati OH
Raymond E. Ross - Cincinnati OH

Assignee:

Cincinnati Milacron Inc. - Cincinnati OH

International Classification:

B29C 4504

US Classification:

425589

Abstract:

Mold handling apparatus especially adapted for use in a reaction injection molding machine. A pair of platens is supported in a frame, and one of the platens is adaped to be moved toward and away from the other by means of a toggle-type actuation system. The movable platen is slidably carried on a plurality of movable platen guide rods that are contained within longitudinally extending frame members that define the frame for the machine. A stationary platen is pivotally supported by the frame member for pivotal movement about a vertical axis through an angle of approximately 90. degree. The movable mold platen includes a movable mold carrier plate that is pivotally carried for movement about a second vertical pivot axis through an angle of about 90. degree. The pivot axis for the movable mold carrier plate is offset from the longitudinal axis of the machine, in a direction toward the operator, so that pivotal movement of the mold mounting plate causes the mold half containing the molded part to be presented directly to the machine operator. The pivotal movement of each of the mold members permits the mold surfaces to be cleaned, if necessary, and also permits the convenient application of mold release agents, or the like.

Appl. No.:

8/113627

Inventors:

Harold J. Faig - Cincinnati OH
Ronald M. Sparer - Madeira OH

Assignee:

Cincinnati Milacron Inc. - Cincinnati OH

International Classification:

B29C 4580

US Classification:

425145

Abstract:

An injection molding machine utilizing vector controlled AC induction motors in its servomechanism drive systems. Vector controlled AC induction motors provide a cost effective high power drive system which superior performance capabilities. Further system efficiencies are realized when the control is configured to run multiple motors by multiplexing the computer controller circuits for the power sections of each motor.

Filed:

Jun 23, 1989

Appl. No.:

7/370669

Inventors:

Harold J. Faig - Cincinnati OH
Ronald M. Sparer - Madeira OH

Assignee:

Cincinnati Milacron Inc. - Cincinnati OH

International Classification:

B29C 4577

US Classification:

425145

Abstract:

An injection molding machine utilizing brushless DC motors in its servomechanism drive systems. Brushless DC motors provide a cost effective high power drive system which has the simplicity of control of brush-type DC motors. By utilizing higher resolution encoders and controlling pressure with the servomotor velocity control loop, motor cogging and zero velocity oscillatiions are minimized.

International Classification:

US Classification:

425150

Abstract:

A hydraulic injection molding machine incorporates a pump driven by a variable speed motor preferably of the brushless DC type. The machine controller outputs driving signals to adjust the speed of the motor so that the flow delivered by the pump substantially matches the hydraulic demand imposed during each phase of the machine operating cycle. The pump is preferably a variable displacement type and is connected to a fast responding pump control for selectively carrying out pressure compensation or flow compensation. The values of the motor driving signals are calculated so that the motor/pump combination is operated at or near maximum efficiency except when the pump control varies the displacement of the pump to effect pressure or flow compensation. Hydraulic transient response is further improved by connecting the output of the pump to an accumulator by way of a check valve.
