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

Door trim locators and heat sticks are designed and analayse the draft angle of the part .

The command enables youdraft analayis to detect if the part you drafted will be easily removed. This type of analysis is performed based on colour ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.

Tooling direction is the main consideration for plastic part and mould parts because it defines the movement of the mould part and the possibility of the plastic part coming out from the mould part (Core and Cavity).

In Molding, machine arrangement is given to open the mould along a direction which is known as Tooling Direction.In other words. The mould is built from two separate halves . and tooling direction basically defines the direction of mould pulls apart.Tooling direction is known as primary direction.

draft analiysing of this part completed .i created tooling axis for this part beacause of 100 presentanage draft geting this part.

No parts can be ejected from the tool if it is having a straight 90-degree profile from its base surface. A small draft angle is provided to each and every area of the component in order to get easy removal of the component from the tool.

Here we are providing a direction in which components should eject in order to get easy removal of components from the tool. In other words, it also lets us know whether the model is having a draft angle and how much is the draft angle from the tool direction.

Because of the need for resin or metal to flow through the die cavity, parts that provide relatively smooth and easy internal flow paths with low flow resistance are desirable. For example, sharp corners and sudden changes or large differences in wall thickness should be avoided because they both create flow problems. Such features also make uniform cooling difficult.

Thick walls or heavy sections will slow the cooling process. This is especially true with processes since plastic is a poor thermal conductor. Thus, parts with no thick walls or other thick sections are less costly to produce.

An easy to manufacture part must be easily ejected from the die, and dies will be less expensive if they do not require special moving parts . that must be activated in order to allow parts to be ejected. Since undercuts require side cores, parts without undercuts are less costly to mold and cast.

The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dyeline or the Tooling Direction.

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.

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

Heat staking is the process to attach two separate components together by melting the base plastic material into a shape that will hold the secondary component. It’s a permanent attachment method that does not require any additional material such as an adhesive or a solvent to make the permanent bond. The only addition is the heat applied to melt the plastic and a tool to shape the plastic to form the mechanical connection.

A work-piece free in space can move in an infinite number of directions. For analysis, this motion can be broken down into 12 directional movements or degrees of freedom. All 12 degrees of freedom must be restricted to ensure proper referencing of a work-piece.
