Hydraulic Cylinder Machines

Hydraulic Machines such as injection molding machines use hydraulic cylinders for molding processes including part production, molding undercuts, and part ejection. Hydraulic Cylinder Machines use hydraulic cylinders to resolve limitations associated with traditional mechanical slides, core pulls, unscrewing devices.

When molding undercuts where the molded part requires a long pull distance, the cam pin could be extremely long. Using hydraulic cylinders may resolve this limitation associated with a mechanical cam design. Another Hydraulic Machine application is a Hydraulic Unscrewing Device which uses Hydraulic cylinders to create the unscrewing mechanism. This hydraulic cylinder application makes sense when there is a high thread count, which would require several rotations using a traditional spline system.

Part Ejection plays a key role in cycle time and in most cases the molding machine actuates the ejection system in the back half of a mold. Parts with complex designs including unique gate locations that require the ejection process to reside in the front-half of a mold can benefit from the use of a hydraulic cylinder driven ejection system.

Hydraulic Machines and hydraulic cylinders are commonly used for molding process optimization. Hydraulic Machines often have internal signals for “mold open/close” as well as signals for ejector positions which are applied to trigger Hydraulic Cylinders and cores. Hydraulic Machines also use external signals to position a hydraulic cylinder to prevent costly mold crashes.
