Door Trim Lower with Engineering Features
Draft Analysis:
Draft analysis helps to detect if your drafted part is easily removable from the mold (in case of plastic component) or die (in case of sheet metal). All plastic components will have a minimum draft of 0.5 to 3deg. And for automotive sheet metal parts the draft will be 7deg or more. If a mold wall is perpendicular to the part ejection, there is ample friction or interference between the mold and the part which will not allow one to release from the other. This is why design engineers give a minimum draft to the part.
CREATING TOOLING AXIS:
- Intersected the plane on class A
- connected two out points by line.
- Excruded the line by taking the point on the surface
CLASS A DRAFT ANALYSIS:
CLASS B:
Just Offseted the Class A for 2.5mm & performed some modifications as per requirement.
CLASS C:
Took a boundry for class A
Sweept using boundry & Reference surface.
CLOSED SURFACE:
Trimed Class A,Class C with Class B.
SOLID PART ON DOG HOUSE 1 DRAFT ANALYSIS:
DOG HOUSE 1 DRAFT ANALYSIS:
As the Draft was around 3deg we have done it for 0.48 deg
