Week 9 - Attachment Feature Creation - Challenge 2
- Aim: To capture the features link dog house and boss.
- Method:
- Stepwise procedure to create the bose and dog house is given below.
- Dog house is an engineering feature used in the plastic trim design. Dog houses are used as supporting feature. Sometimes other engineering features like snaps; locators etc. are mounded on them to increase their strength.
- Dog houses are subjected to draft analysis to prevent breakage of the component during ejection from the mould cavity. Dog house and other engineering components are built on B-surface.
Wall thickness = 0.70 x Thickness of the plastic material
Fillet on the inner side = 0.25 x Thickness of the plastic material
Fillet on the outer side = 1.25 x Thickness of the plastic material
Fillet on the coring edges = 0.25 x Thickness of the plastic material
Coring thickness = 0.40 x Thickness of the plastic material
Draft angle 2deg to 3deg
