Discuss how to design mold lifting devices.

[[email protected]]

An injection mold lifter has two main components: the body and the forming parts. They are therefore classified into two categories: integral and non-integral. An integral lifter is generally more robust and durable in construction. It is often used in molds for larger or more complex features. In the case of a non-integral lifter, an additional element is added to the mold, which is usually not part of the original mold structure. This type of lifter is somewhat flexible when it comes to replacement and modification. It is often used for molds of small components that require regular adjustments.

Types of mold lifters
Another applicable type of mold lifter is a pneumatic lifter. fan databaseThis type of filter is operated by compressed air. Generally, large molds or molds that are difficult to open using a toggle clamp are lifted by pneumatic lifters.

The hydraulic mold lifter uses hydraulic power to accurately position and lift the mold. Suitable for handling heavy molds and complex parts.

Electric mold lifters drive the lifting mechanism using electric motors. They are appreciated for their efficiency, precision and cleanliness.


Main components and features of mold lifters.
Mold lifting rod
It is the main part that engages with the molded part. Its movement allows to lift and eject the finished product, especially those with complex shapes. The shape of the rod is such that it resembles the specific geometry of the part to be molded.

Guide pin
It is the component that helps keep the push rod in its correct alignment during movement. It can be hydraulic systems, cams or other elements. springs that provide the necessary force and movement. The lifting mechanism depends on the requirement of the parts since it applies to different types of movement: angular, vertical or lateral.

Cam system (motion dependent)-
A cam system can be used when angular motion is required. The cam translates rotary motion into linear motion, allowing the mold lift rod to move at an angle.
