Manufactured Mold Designs

A quick look at our manufactured mold designs so far:

Body Cavity Mold

Hole in the center of the cavity mold will be used to suspend the nut for the shaft within the plastic

Body Core: Features 6 symmetric ejection holes, allowing for removal of the body from the core.

During machining, we had to make some changes to the part.
Due to the size of the body part, we ended up using a thicker (1.25") mold blank for the cavity at Dave's suggestion. Ideally, we would have used the thicker blank for the core as well, but Dave is sure either would work. Also, the runner on the cavity mold was originally 0.030" deep, but Dave suggested deepening it to 0.090" deep to allow the molten plastic to flow into the mold better.

Ring Cavity Molds
Design Features: 2 additional runners added around the mold, create fingers which can be used to eject the rings off of the mold

Bugs Bunny Core Mold
Design features: 10 ejector pin holes, easily spaced to allow for ejection of disk after injection molding
