The smaller clamping force can be used to obtain a larger clamping force by using the linkage mechanism to enlarge. Improved mold clamping speed, saving power consumption. At present, single-elbow and double-elbow hydraulic-mechanical clamping devices are commonly used.

The characteristics of the hydraulic-mechanical clamping device are as follows:

It has a boosting effect and can reduce power consumption.

With self-locking function, even if the oil pressure is removed, the clamping force will not disappear, and the mold lock is stable and reliable.

The moving speed of the template is changed, from fast to slow when the mold is closed, and then slow and then fast when the mold is opened, which makes the opening and closing of the mold more stable, avoiding the impact and collision when the mold contacts.

The toggle lever mechanism is easy to wear and requires high rigidity and wear resistance.

When the thickness of the mold changes, the distance between the movable template and the fixed template needs to be adjusted, so the mold adjustment is relatively troublesome.

The clamping force must be measured with a professional instrument and is difficult to adjust.
