Week 9 - Project 1 - Door Trim Lower with Engineering Features

MMadhur Shrivastava27 Sept 2022

AIM:

To Create the Door Trim Lower Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

Create the Heat Stakes and the locators considering the design rules mentioned in the video for the door applique.

OBJECTIVE:

To create the Base Bracket Plastic from the given Class A.

To ensure the all the sketch and tools in the Geometry set.

Give the proper name of the Geomatry set.

Create the Class B ad Class C.

The objective of the project is to design the car bumper and to do a draft analysis for it by creating the required tooling direction with the help of Bisecting method.

Create the Locator ans Heat stakes.

INTRODUCTION:

With draft analysis, you can verify draft angles, examine angle changes within a face, as well as locate parting lines, injection, and ejection surfaces in parts.

Drafts are defined on molded parts to make them easier to remove from molds. There are two ways of determining the objects to draft: either by explicitly selecting the object or by selecting the neutral element, which makes the application detect the appropriate faces to use.

To create the Geomatry set with proper name and sub geomatry set also.

A positive draft means the angle of the face, with respect to the direction of pull, is more than the reference angle. Negative draft. Displays any faces with a negative draft, based on the reference draft angle you specified.

RIB:

Ribs are a feature in plastic injection molded parts. They are thin extensions that run perpendicular from a wall or plane. They are commonly used to provide additional support and strength to a part. Thickness and location are essential to rib design.

HEAT STAKES:

Thermal staking is an assembly method that uses the controlled melting and reforming of a plastic stud or boss to capture or lock another plastic or metal component of an assembly in place. The plastic stud protrudes through a hole in the component to be locked in place.

LOCATORS: It is a feature which is used to arrest the degrees of freedom for the components being assembled.

TOOLIN AXIS:

The direction in which the mold or core and cavity opens is the tooling axis. Connectivity of Class-A surface: Checking the connectivity of the surface, this can be done by creating boundaries or by simply using the join option such that any openings can be easily visualized.

Create the Toolig Axis by the Bisection Line Command. First create the intersection of the Surface A and we get the line.

Draw the line on the Intersection curve extrant it. By the help of two line Draw the Tooling Axis.

Draft Analysis :

The part created has to be changed to material mode in display frame.
Compass is enabled and align it along with the tooling direction.
Lock command is then applied to fix compass along with tooling axis.
Color codes are classified and Draft angle is applied.
Running point analysis is used to display permissible draft angle.

Draft analysis - Final component :
