Mold Design of Ice-tray

Given Task:

Material thickness of the part is linked to an expression. The material thickness is able to change by +/- 15% of the nominal value chosen without any feature of the model failing (i.e.: blends, offsets, etc.). Nominal value chosen for material thickness is at your discretion.

The ice cube tray must be able to scale in length, width, and height by +/- 50% of nominal without features in the model failing. The length, width, and height are to be driven by expressions.

The number of pockets in the tray are to be scalable. The tray must have a minimum pocket pattern of 2 by 6 and must be able to scale up to a pattern of 3 by 10. The size of the pockets is derived from the length, width and height of the overall tray and take into account the number of pockets in the pattern. The number of pockets does not dictate the overall size of the tray. The pattern is to be driven by expressions.

The two halves of the mold created use a subtracted linked body from the ice cube tray part to create the cavities in the forms and have their geometry update when the configuration of the ice cube tray part change. The mold cavities are to account for material shrinkage after cooling and are to be 1% larger than the nominal part. An appropriate parting line is chosen. The two halves of the mold are able to separate, and a part can successfully be removed (no undercuts, and proper draft).

Create an assembly drawing with an exploded view showing the ice cube tray part, and the two halves of the mold in an open position. Create a parts list for the components and balloon the drawing. Use the master model method to create the drawing.

No features fail on the model when sizes are changed within the specified boundaries.
