DESIGN OF ‘PLASTIC INJECTION MOLD’ FOR AN ‘AIR VENT BEZEL’ THROUGH FLOW ANALYSIS (CAE) FOR DESIGN ENHANCEMENT

Jitendra Dilip Ganeshkar, R.B.Patil

Abstract: Designers of plastic injection Molds need to study from this point of view, the type of Mold to be designed, the physical Mold orientation, the dimensions for each of the element in the Mold, the location of the gate, runner, requirement of insert, draft angle requirement, shrinkage factor, location of cooling channels. Design can also be simplified by using standardized parts of the mold such as ejector pins. By eliminating the obstruction to smooth flow of plastic a good of quality component can be achieved. The effort of this thesis work is to find out the nuances in the Plastic Injection Mold Design while borrowing the inputs from the Flow Analysis (CAE) conducted for the Air vent bezel to study the behavior of the Melt during flow. The Mold Design would incorporate suitable checking to ensure the best quality product in terms of `defect-free’ output. This thesis work consist methodology of plastic injection molding process, material requirement, how to overcome weld mark, shrinkage etc to satisfactorily assemble the component.

Keywords: Draft angle, Shrinkage, CAE, weld mark
