Interlock design for plastic enclosure
(OP)
Hi all,
I am working on an interlock design for electronic enclosure. My problem is to design a feature interlock A which can achieve the following:
#1: hold enclosure in vertical direction
#2: hold enclosure in horizontal direction
Details are listed in pic 1 & 2 at website: http ://hk.pg.p hotos.yaho o.com/ph/l eonlai1900 /album?.di r=/c328scd
Pic 1 shows the bottom view of top cover with the feature A shown. Interested item.
Pic 2 shows the assembly view (cross section) & the relationship between top & base cover & the interlock A with base cover's features.
Please help out. Can my proposed feature A (interlock feature) can be easily made in tooling? Please advise.
Regards,
engmechs

The doubly undercut feature would be extremely difficult to extract from a mold. The mold would have to be extraordinarily complex, too.
Additionally, the hook it engages is too short and would fracture while being deflected during assembly.

Is there any way to get around this with a simplified feature?
Please advise on this.

Take it all apart.
Measure, draw, and learn. I.e., steal the designs.
