Mold locking unit

Customer requirements: The mold locking mechanism is reliable and durable, the mold protection function is effective, and the mold opening position repetition accuracy is high.

Solution: Based on existing mature mold locking mechanisms, through in-depth research, 12 key elements are proposed for optimization and innovation, including:


1-Equal-stress pressing die technology

The mold locking force is evenly distributed and the mold deformation is small;

Using a lower mold locking force, producing the same product will not cause molding problems, while protecting the template and mold.

2-High rigidity T-groove formwork

The whole series of formwork is designed with high rigidity, and the overall rigidity of the mold locking unit is increased by 30%;

The full series of standard T-shaped slots facilitate mold loading and unloading, reduce the probability of tooth damage due to long-term use of screw holes, and improve the service life of the template.

3-Forced reset of ejector pin

The standard ejector pin forced reset meets special mold forced reset requirements, and the mold has a wider range of applications.

4-Closed loop control of mold opening position

Improve the positioning accuracy and repetitive accuracy of mold opening position, meet the requirements of precise extraction of robot hands, and facilitate automated and continuous production.

The positioning accuracy is<2mm, and the repetition accuracy is<0.3mm.

5-Unique anti slip foot design

Using a unique anti tipping and sliding foot design, it improves the smoothness of movement, reduces friction, improves movement efficiency, reduces energy consumption, and avoids template tilting to protect the mold.

6-Low voltage mold protection function

Configure a low-pressure mold protection control unit to ensure effective mold protection.
