Week 8 - Challenge 3 - Coin Holder Design

Aim:- The objective of this report is to Create the Coin Holder Plastic component through the given Class-A surface and and perform Draft Analysis on Class A Surface and the final component or the Solid part.

COIN HOLDER CLASS A SURFACE:-

TOOLING AXIS :-

• To create the Tooling Axis first we need to decide the core and the cavity side.
• After deciding which side will be on the cavity part and which one on the core part then we can easily get our tooling direction.
• Now we have to identify the faces on which draft angle should be given so that it clears the Draft Analysis test.
• In this component as we have a flat base so the Tooling axis must be normal to the base.
• First a point is created at the center of the face then a line is drawn normal to the surface which becomes our Tooling Axis.
• Now we can perform our draft analysis and check if all the faces have a draft angle or not.

DRAFT ANALYSIS:-

• Draft Analysis is carried out in order to check that all faces have a proper draft angle (minimum 3 degree) in order to manufacture the component easily.
• Draft Angle is given on both the outer and inner faces so that during ejection of the component from the mold the part will easily be ejected without having much rubbing friction.
• If draft angle is not provided to the parts, then during ejection of the part the entire part would get rubbed against the core and cavity and there will be much rubbing friction induced which will make the ejection process more difficult and as a result the part, core and cavity will get damaged.
• In order to avoid this issue Draft Angle is given on all faces.
• Now the draft analysis can perform by the reference of the Tooling Axis.

DRAFT ANALYSIS OF THE CLASS A SURFACE :-

COLOR CODE:

• GREEN COLOR: For draft angle more than 3 degree.
• BLUE COLOR: For Negative draft angle.

• From the above draft analysis, we can clearly observe that there all the face of Class A Surface are above 3 degree so it is follow the Draft Angle rule for the component to get manufactured.

DRAFT ANALYSIS OF THE FINAL PART :-

• From the above draft analysis, we can clearly observe that there all the face of final closed Surface are above 3 degree so it is follow the Draft Angle rule for the component to get manufactured.
• we Take the Thickness of the component is 2.5 mm.
