Hydraulic cylinders are widely used in the mold industry. When the buckle stroke is greater than 45mm, we will choose the hydraulic cylinders core pulling.
Characteristics of a hydraulic core pulling mechanism:
1. The slider has a long stroke and a large core pulling force.
2. The parting and core pulling are not restricted by mold opening time and ejection time.
3. The movement is smooth and flexible.
Design Points.
1. The cylinder has no rigid clamping force. It is forbidden to use a hydraulic cylinder to clamp the mold. Unless the slider is not affected by the expansion force in the sliding direction. Otherwise, wedges must be designed.
2. Prevent the slider from interfering with the movable and fixed mold.
3. Prevent the hydraulic cylinder from interfering with the injection molding machine.
4. Support seats must be designed for fixed hydraulic cylinders. And do positioning for the support base.
5. T insert connection can be used to connect with the slider base.
6. Mold spacer block must be designed when the oil cylinder is installed on the ground to prevent the oil cylinder from being damaged.
