Mold clamping system

Precise and problem-free positioning of your molds with less force. ETDC movable mold clamps are a convenient solution to further automate rapid mold changes.

ETDC Movable Mold Clamps

This type of jig clamp is connected to a chain that is driven by an electric motor.
The ETDC is part of the range of quick mold change systems for shorter set-up times (SMED). Another solution from EAS especially for sheet metal working machines and vertical injection molding machines. Movable mold clamps are widely used on machines with a moving bolster.

Operation ETDC

A single acting pull/T-slot cylinder is connected to a chain that moves to the T-slot of the carriage. The chain is driven by an electric motor.

Usually a press has two moving bolsters. One with the mold that is in production and one that is ready outside. The new mold is already clamped (lower half) and ready for the mold change. The bolster therefore goes in and out of the press in its entirety.

The quick mold change assisted by movable mold clamps works as follows:

1) production stops
2) the upper mold half is released via the movable mold clamp
3) the first moving bolster goes out of the press
4) the second moving bolster (with the new mould) enters the press
5) the upper mold half is clamped via the movable mold clamp
6) ready for production

The hydraulic clamping cylinder is normally retracted into the so-called parking position and monitored by a sensor. When the cylinder moves to the T-slot and reaches the jig to clamp, another sensor indicates that the clamp cylinder has reached its position.

Application

Movable mold clamps are used on large die-cutting machines with a wide variety of mold sizes. Particularly on the carriage, large molds of different sizes can be automatically clamped with these clamps. Typically, 8 to 16 of these clamps are mounted on the carriage.
