This is a summary of a proiect undertaken during my university studies. The objective was to design a die cast mold for a carburettor from an incomplete 3D scan of a part.

To begin the process the point cloud data from the scan was imported into Creo Parametric and referenced to create a solid model of the part.

Rounds and drafts were added to aid the ejection of the part from the mold.

The material to be used was selected and researched to apply the appropriate shrinkage to the part.

 

Mold sections were created by referencing the part, it's shape was then generated into the dies.

Mandrels to make the holes in the part were created and integrated into the existing sections.

 

An opening sequence was established and ejector pins were positioned.

Water lines for cooling were created to increase production rate.

Simulations of post processing using CNC milling/drilling to remove unwanted drafts from functional surfaces was conducted.

 

To finalise the manufacturing process the values for the relevant cutting parameters were calculated and the machining time optimised.
