Plastic Nozzle Moulding Of Dust Catcher

The design of plastic dust catcher nozzle mould

It is rare to see the structure of a slide coming out of a lifter in plastic injection moulds. We are not experts, but we just design a typical mechanism that works quite well based on our experience.  Hope that it helps you.

1. Mold Design Concept

If we use a common mould slide, the steel circled in red gets stuck. And the undercut could not be released with this.

2. How to design a lifter head?  

The green block is a lifter with a prominent tail while the purple block is a slide which is to release undercut and drive lifter to release undercut downwards.

3. Further explanation on slide out of lifter in plastic injection mould

Mould lifter needs a limit screw to limit the stroke of the lifter traveling down while the spring is to prevent the lifter from moving right with slide.

4. The science of the structure of slide from the lifter  

Angel lifter drive slide to move right And slide insert drive lifters to move downwards while releasing undercut. Spring works to prevent the lifter from moving right with the slide which stops after a certain stroke and will be locked by the limit screw.

This is only our basic design. You are welcome to provide suggestions for better improvement by writing us an email.
