Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

Draft Analysis on a Fan Cover

OBJECTIVE:

To perform a draft analysis test on a fan cover given as the input.

REQUIREMENT:

A minimum of 3 degree draft on all the faces of the fan cover from the main tooling axis.

TOOLING AXIS:

Tooling axis or tooling direction is also known as the direction of the mould.All plastic components will follow the tooling axis procedure.

DRAFT:

Draft is given on all plastic products which are injection moulded or which undergoes different moulding techniques.Draft is given for a product to ease of removing the product from the core after the mould cycle is complete.

GIVEN INPUT:

PROCEDURE:

As a plastic product designer we need to ensure that the component can be tooled completely from the main tooling in order to avoid side cores.

First and foremost we need to analyse the component from which direction it can be tooled.In X and Y it can't be tooled in a single tooling as the component as a hole on the top.

Here in this scenario we create two different lines from X & Y direction and from it we create a bisecting line in Z direction to create the tooling axis.

Tooling in Y direction:

Tooling in X direction:

Bisecting X&Y Tooling :

Bisecting method is used to create a line from two bisecting lines .Here we take X and Y tooling lines and the point as reference to create the bisecting line.

DRAFT ANALYSIS:

Now using the main tooling as reference we need to check whether the component passes the 3 degree draft analysis requirement.

The dialogue box infers that the component has a draft of more than 3 degree.

VARIOUS ORIENTATION OF THE COMPONENT:

TREE STRUCTURE:

CONCLUSION:

Concluding the tooling axis is created and the draft analysis check is done for the given input
