Computer-Aided System for Multi-Cavity Die-Casting Die-Design

چکیده
Die-design for the die-casting process is a time consuming and complex activity that requires domain knowledge and vast experience of the die-designer besides information about manufacturing resources, part geometry, delivery time and cost preferences, etc. Complexity of the die-design activity further increases in case of a multi-cavity die. Currently available die-design systems lack in the level of automation and do not explicitly address multi-cavity die-design. In the present research work an attempt has been made to develop a computeraided system, which facilitates design of a multi-cavity die-casting die taking part product model as input. Objective of the proposed system is to automate the process of cavity design, cavity layout design, die-base design, core-cavity and side-core design, gating system design for a multi-cavity die-casting die. The proposed system, which we named Multi-cavity Die Designer, works as an add-on application to an existing CAD software namely SolidWorks. The proposed system is divided into five modules, namely Data Initialization, Cavity Design, Cavity Layout Design, Core-cavity& Side-core Design, and Gating System Design. Use of commercial software like SolidWorks as a platform both for part design and generation of die-design eliminates loss of data which makes the proposed system quite useful in the industrial scenario. To demonstrate the capabilities of Multi-cavity Die Designer, it was tried for a number of die-casting parts and the results for one industrial case study part are presented. Proposed system is a step forward to design-manufacturing integration for die-casting process.

Diecasting is one of the forming methods which is used for producing large number of components with good surface finish by injecting cast alloys in a metal mould under high pressure. Design of a diecasting die requires human expertise and is normally performed by trial and error method, which leads to monetary and time loss. Automation at initial die design stage will result in higher producti...

Die casting process is used since long, but even today problems like erosion, corrosion, soldering and sticking affect die life. These dies undergo thermal cyclic loads from 70 oC to 600 oC during processing. Physical Vapor Deposition (PVD) hard coating can play an important role in such extreme applications. In the present work, we report the use of Chromium based multila...
