Friction clamp for injection molding machine |
摘要 |
A friction clamp assembly for securing a mold of an injection molding machine in a closed position includes a column rigidly secured to a moving platen carrying a mold half and a gripper bush assembly for frictionally engaging and locking the column in a desired position. The clamp assembly further includes a clamp piston for clamping the moving platen in a mold closed position. The clamp assembly transmits a clamping force to portions of a moving platen other than end portions via the column so that platen parallelism is maintained during closing, injection and hold pressure portions of a molding cycle while platen bending is substantially avoided.
