Week 9 - Attachment Feature Creation - Challenge 2

DOG HOUSE;

Dog house is an engineering feature used in 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.

ENGINEERING FEATURES:

Dog house is an engineering feature used in 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 mould cavity. Dog house and other
engineering components are built on B-surface.

DESIGN CONSIDERATION FOR CREATING DOG HOUSE:

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.
