Abstract
In a mold closing unit for use in an injection molding machine for processing synthetic materials a stationary mold carrier and a movable mold carrier are provided. A pressure cylinder comprising a pressure piston serves for building up the locking pressure and at least one piston-cylinder-unit serves for moving the movable mold carrier. The drive piston or drive cylinder are interconnected with the pressure cylinder. The pressure cylinder and the movable mold carrier constitute a motion unit displaceable relative to the stationarily mounted pressure pistons.
Claims9
In a mold closing unit for use in an injection molding machine for processing synthetic materials, including
- a stationary mold carrier,
- a movable mold carrier constituting a mold tentering space together with said stationary mold carrier between said movable mold carrier and said stationary mold carrier,
- pressure cylinder,
- a pressure piston located inside said pressure cylinder to build up a locking pressure,
- a piston-cylinder-unit for transferring the movable mold carrier into and out of a closed position with said stationary mold carrier for closing parts of a mold within said mold tentering chamber;
- said piston-cylinder-unit having a drive piston and a drive cylinder;
- one of said drive piston and said drive cylinder of said piston-cylinder-unit being interconnected with said pressure cylinder,
- the improvement wherein
- said pressure piston is stationary with respect to said stationary mold carrier and
- said pressure cylinder and said movable mold carrier constitute a motion unit displaceable relative to said pressure piston.
