Abstract: The invention relates to a hydromechanical tool or workpiece clamping apparatus comprising at least one spring clamping cylinder connected to a release conduit and adapted to be hydraulically operated against a spring force to a release position, a pump connected to said release conduit and operable for a release operation, and a discharge conduit extending from said release conduit to a fluid reservoir and including a discharge control element for discharging the pressurized fluid from said spring clamping cylinder to said reservoir after deenergization of said pump. A known clamping apparatus of this type has a solenoid poppet valve disposed in said discharge conduit and operable to close said discharge conduit for the release operation and to be actuated to a flow-through position and maintained therein for the clamping operation. The solenoid valve is expensive and requires separate control means. In contrast thereto, the invention provides the use of a discharge control element in the form of a simple bypass shutter the flow resistance of which at a constant output flow rate of the pump is greater than the pressure required for overcoming the spring force in a release operation.

Title: Mould exchanging apparatus for a plastic injection moulding machine
IPC: B29C45/17
Filed: 1987-03-23
Granted: 1991-03-13
Abstract: The mould exchanging apparatus, serving a plurality of plastic injection moulding machines, comprises an exchanging table (27), which serves as transporting carriage and can be moved in a linear guide (45) to a depot (44) for injection moulds as well as to the plastic injection moulding machines, aligned in parallel with the guide (45), in connecting position for the mould change. Two mould receiving places are arranged one behind the other on a rotatable carrier plate (27h) on the exchanging table (27). In the connecting positions, mould guides (G") of the receiving places, with the carrier plate (27b) turned if need be, form alternately with a mould guide of the mould clamping space of a plastic injection moulding machine and alternately with a mould guide of a depot receiving place (44a) transport tracks for the exchanging of an injection mould. It is achieved by such a design that the injection moulds of an entire group of plastic injection moulding machines can be exchanged fully automatically with the exchanging table (27), provided that the said machines are arranged in a space-saving manner with respect to the mould depot (44). This arrangement avoids running over the operator sides of the plastic injection moulding machines, and consequently the operator, following an upright transporter. <IMAGE>
