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

DOOR TRIM LOWER WITH ENGINEERING FEATURES

AIM:

To create a door trim lower with engineering features following design rules.

DESIGN PROCEDURE:

INTRODUCTION:

CLASS A SURFACE:

TOOLING AXIS:

Tooling axis is ths importand features of the plastic component design ii will desides to open and close of core and cavity of machine.
Before create a tooling axis has to analysis class A surface which is best place to located.
After desiges the of tooling axis extract surface which the tooling axis place.
Then create a point at the middle of the surface.
From that point create a line then namded as tooling axis.

CLASS B SURFACE:

Class B surface is the bottam surface of the component which engineering features are create from this surface.
To create class B surface for that offset the class A surface at the 2.5mm in downwards direction.
In offset surface has form a patch surface.
From that surface has to make extrapolate the surface at the both end.
After that trim the surface from the extrapolate surface.
Then give the fillet to the edges then named has class B surface.

CLASS C SURFACE:

Class A surface is act like a thickness of the class A and class B surface.
In class C surface have to clear draft analysis for that use sweept command.
Using the sweept command two method to create a class C surface.
In sweept command in subtype obtion select the with draft direction give guide curve and give draft direction.
While create C surface with draft direction method give angle of 3deg.
Another method is with referance surface give guide curve and give referance surface.
Using with referance surface method give angle of 93deg.
To create C surface is be in two or more division.
After that use join cammand join the division surface.

COVERSION OF SURFACE:

After creating the C surface use join command join the class A and class C surface.
Then unhide the class B trim with class A and C.
Then form a surface modeling of the door trim lower.

COVERSION OF SOLID MODELING:

After creating surface modeling then go to part workbench then use close surface select the surface give ok.
Then created the solid features of door trim lower.

ENGINEERING FEATURE:

4 WAY LOCATOR:

4 way locator is the use to fix the component then arrest the degeer of freedom.
The 4 way locator is use to arrest the x axis and the x axis rotation.
And also arrest rotation axis and z axis .
The locator is much be in greater than heat stake.

HEAT STAKE:

Heat stake is use to join the two surface it's act like a weld.
In door trim component heat stake will be use to joined surface at permanant.
To create a heat steke need extract the surface for the final component .
Then create a plane and sketch the heat skake at the design rule.
The diameter of the heat stake it will desides by moulding team.
Rib will be create at the bottom of the every heat stake to support from the impart.

DRAFT ANGLE ANALYSIS:

CLASS A SURFACE:

While analysis the class A surface all area are clearing but have maintain the draft angle much be in 3deg then will be B surface also clear.

FINAL COMPONENT:

OVERALL VIEW:
