Function and differences between slider and lifter mechanism
Could anyone explain to me the function and differences between slider and lifter mechanisms in an automotive plastic part, please. Maybe some example 🙏🏽

Ohhn, I didn't understand that you were talking about plastic injection. I'm sorry I can't help you with that issue. However, I think there are specific groups that you could consult:
https://grabcad.com/groups/plastic-products-and-mold-design
https://grabcad.com/groups/plastic-product-and-mold-designing-site
https://grabcad.com/groups/3d-injection-molds-for-thermoplastics
In the meantime you can consult places on the internet like this:

I hope they can help you!
Kind regards,

PS: as an initial guide I also share the response of the AI Copilot:
Certainly! In the design of injection molds, both sliders and lifters play crucial roles in the opening and closing process. Let’s explore their differences:
Slider:
Function: Slides along a guide rail to change the shape and size of the die nut, enabling demolding.
Movement Direction: Moves horizontally or angularly within the mold cavity.
Applications: Ideal for horizontally oriented undercuts, side draws, and interior cores/details.
Complexity: Typically more complex in construction to guide movement.
Actuation: Commonly driven by hydraulic or electric means for linear or rotary motion.
Lifter:
Function: Utilizes a tilted top plate mechanism to push the lifter upward or downward for product demolding.
Movement Direction: Moves vertically up or down within the mold cavity.
Applications: Best suited for vertically oriented undercuts and interior cavities/pockets.
Complexity: Usually simpler in structure, focusing on vertical up/down movement.
Actuation: Often driven by mechanical mechanisms like springs and top bars, ensuring reliability and stability1.
For an automotive plastic part example:
Imagine a car dashboard with intricate interior details. A slider could create the textured surface of buttons, while a lifter might handle the vertical undercuts around the air vents. Each mechanism contributes to the final part’s functionality and aesthetics2. 🚗🔧
