Week 9 - Project 1 - Door Applique Design with Engineering Features

CREATION OF HEAT STAKES & LOACTORS FOR DOOR APPLIQUE

OBJECTIVE: The main objective of this challenge is to create tooling axis for the Door Applique surface considering the draft and to create class B and C surfaces using class-A and adding heat stakes and locators to the final solid component and to perform draft analysis.

Taking the Thickness of the component to be 2.5 mm

Tooling axis: The direction in which the mold or core and cavity opens is the tooling axis.

Heat Staking :

In manufacturing products with thermoplastic components, it is often necessary to join a thermoplastic to a part of dissimilar material, whether it be metal, a dissimilar plastic, or other material. This technical information sheet provides design guidelines, configurations, and techniques for successful thermal (heat) staking.

Heat Staking is a pulsed-heat process to join two or more parts out of which one at least is made of plastic. The process is to deform the plastic material using heat and force at a set process time. The bond is made by partially de-forming the plastic part in order to fix the other.

Heat Staking makes it easy to bond metal to plastic and is commonly used in high volume/low cost applications such as automotive, IT and

consumer appliances.

Locators :

Locators are used in parts to arrest motion between parts. There are two classifications of Locators, 2-way and 4-way. A simple method to remember the difference between them is to consider the 3 axes of translational motion, and the 6 corresponding directions or Degrees of Freedom. A 2-way locating pin restricts motion along 1 axis (or 2 degrees of Freedom), like a round pin in a slot. Likewise, a 4-way pin restricts 4 degrees of freedom along 2 axes. A round locating pin located concentrically in a hole is a common application of a 4-way pin, and helps to further secure the piece. In order to sufficiently locate a part, a minimum of one of each type of pin is required to prevent excess motion of the workpiece, and more locating components may be used as needed.

Creation of Locators

1) Create a sketch and Draw the sketch of the Locator

4 way locators

2 Way locators

2) Pad the Created sketch

3) Give Draft and edge fillet to it

4) Copy paste as much as we required

5) Union trim it with the main body

Creation of Heat Stake

1) Create a sketch and Draw the sketch of the Heat stake

2) Pad the Created sketch

3) Give Draft to it

4) Copy paste as much as we required

5) Union trim it with the main body

Creation of Counter part Holes

1) Create a circle sketch for making holes on the other part to make the heat stakes and locators to pass through.

2) Pad the circles

3) Remove these pad cylinder from the other Attachment part

DRAFT ANALYSIS

CONCLUSION

Heat Stakes are created on Door Applique with 0.5 draft. Hence provided Draf axis.
