The electric mold carrier

Swinging out of the lower mold clamping platen to both sides enables simultaneous operation of the mold carrier from both front and rear. A shuttle variant allows the lower mold clamping platen to be extended and retracted horizontally for a free handling position or an easy and fast tool change 

The large opening stroke allows enough space between the tool halves for process automation (e.g., insertion and removal of parts, PUR introduction with open systems, etc.). The mold carrier can be employed as a stationary mold carrier or in mobile systems.

The concept

The parallel stroke is provided by two synchronized lifting belts. The base frame and the driving frame are referenced to each other using reference pins. 

The clamping force is applied to the tools over a wide area using air bags. The lower mold clamping platen can be swung out to either side by a crank mechanism or be extended horizontally by guiding system. 

The upper tool clamping platen is also swung out. For improved operability, the upper tool can also be lowered after swinging out and then locked securely in place.
