Door Trim Lower with Engineering Feature

Intoduction

Design the door trim lower by the given class A surface and make draft analysis of it. The heat stakes, four way locators and two way locators are designed on surface of solid door trim lower. The solid plastic part was created from the Class A, class B and class C surfaces.

Requirements for door trim lower

Tooling axis
Class A surface
Class B surface
Class C surface
Heat stakes
Four way locators
Two way locators
Dog house

Tooling Axis

Opposite faces which are parallel to the center vertical line was projected and the lines trimmed to required length. Using the bisecting line tool the intersection between to projected line from the faces was noted.

other side the same procedure was follwed to find a another intersection line.

Finally the two lines are extruded and intersection line was identified.

Class A surface

The class A surface and the heat stakes location points are given in the question.

Class B surface

Class B surface was just offsetted from the class A surface and some fillets are reconstructed. The offsetted distance was 2.5mm.

Class C surface

Two surfaces are joined and trimmed by the class C surface. This surface was created by the sweep tool. A class boundaries are swept to required length and angle of 90 deg.

Heat stakes

Initially the heat stakes are created with sketch using circular command.

The outer of the hollow cylinderical shape some ribs are attached.

The heat stakes are 5mm less than the four way locator.

Four way locators

The four way locators are designed on respected places where the location assingned for the four way locator.

The paded surface was drafted a surtain angle of 0.5 deg and the edges are filleted to 0.25mm.

Two way locators

Two way locators placed to connect horizontal and vertical surfaces. The purpose of the locator is to give some additional strength to the plastic part.
