Week 9 Challenge
Aim
To design mold for CPU Fan case.
Introduction
A mold is a hollowed out block that sets the shape of the product being made. It can be made of different materials, the most common of which are aluminum, steel, alloys and copper
Procedure
1) CPU Fan case.
In this model there is no sufficient draft given for the part and this will damage the mold hence it is necessary to modify. Me considering as a Mold Engineer I will report this to the product design team to modify the part. once it is revised we can move forward to design the mold.
For the give part it is necessary to provide sliders as there is the presence of the undercut. Here the tools I used are.
a) mold tools
draft analysis,parting line, shut off surface, split line.
b)direct editing
move copy bodies,move face delete body, split ,combine, fillet.
C) surfaces command
Ruled surface, offset surface,lofted surface, surface knit, surface cut.
d) under features
Extrude boss, extrude cut, hole wizard, sketch driven pattern.
e) others
float ,mate,move component- Rotate component ,weldment, also working in assembly.
after designing the mold the sliders has to be made using the split comand to overcome the problem of undercuts.
Given plastic component for which the mold has to to be designed
screenshots of the mold designed
Cavity
Cavity- The cavity is the female part which forms external shape of molding.
Core and the other components of the mold
Core and the Insert
core-The core is the male part which forms the internal shape of molding.
Inserts-in certain case when the depth of the cuts in the designed mold is greater and as it can be manufacturable in the real scenario due to the absence of the tool in this condition the inserts will be designed
Ejector Pin- They apply a force to eject a part from the mold, and in some cases can leave marks. Once the mold is opened, the pins extend into the mold cavity, push the part out, and then retract, allowing the mold to close and be refilled.
Sliders
Sliders-sliders are designed when there is presence of undercut in the plastic component
Conclusion
The mold for the given plastic component was designed successfully
