The Race Begins!
Hare Part Mold Design The hare mold was designed with a scale factor of 1.035 and is shown in the figures below. The part was designed with no draft as it is not necessary given the contours of the part. The parting line was placed at the largest outer diameter in the part. The parting surface was is on the outside of the part and it extends 0.2 inches from the part. The contours that make up the hare features are all located on the cavity. The locations of the mounting holes are based on the referenced mounting holes for the injection molding blocks that already machined. The sprue hole is placed above the part in the mold in both the cavity and core molds. The extrusion in the part, which is meant for the felt part of our design, is accounted for in the core mold, where extruded boss is placed.
