This paper presents a case-based reasoning (CBR) methodology for metal stamping die design, that in particular addresses the indexing and retrieval of die design cases. A feature relation graph representation of stamped metal parts are used to create a high level of geometric abstraction, which is used to index design cases quickly and accurately. Though the potential search space for case retrieval is huge, by employing a novel dual-step similarity analysis between a new stamped part and existing parts in the case library, the proposed retrieval strategy can narrow down the search space efficiently and retrieve the most similar case in a reasonable period of time. An illustrative example is included to demonstrate the operation of the proposed approach and show its effectiveness in speeding up stamping die design.

High pressure die casting is a high volume component manufacturing process which is used extensively in many aspects. There are many factors affecting the quality of die-casting die. In this paper, the CAE simulations of filling and solidification processes for die-casting are studied. Numerical analyses are presented for two practical die-casting parts using HZ CAE software. The temperature distributions and filling states in solidification and filling process are presented. Then the deficiencies of the part are predicted. Based on the analyzing results, the structures of the two dies are optimized and longer die service life and high-quality castings are obtained. It is proved that CAE simulation results can offer a helpful reference for die-casting die design.

The die casting industry has an imperative need for an automated or semi-automated approach for die casting die design. One of the key challenges that die makers face is how to shorten the lead-time to the market and reduce the cost in die design and manufacturing. Most die makers have employed computer aided design (CAD) systems to improve the efficiency and quality of die design. However, conventional CAD systems do not have the functionality specially for the die casting die design, therefore, a specific computer aided system for die casting die design is needed to meet the market demand. This paper describes a prototype system structured by several functional modules as specific add-on applications on a commercial CAD system for die casting die design. These modules include data initialization, cavity layout, gating system design, die-base, parting, standard component design, etc. Focus of the development will be placed on gating, runner and die-base design.

Aluminum extrusion die design involves with two critical parts; die features and its parameters. Presently, die design process is performed by adaptation approach. The previous dies together with their parameters are collected and stored in a database under the well-memory organization. Case-Based Reasoning (CBR) has been applied and enhanced the design productivity. However, the CBR method has an excellent ability only that an exact or similar design features are existed. Reality, aluminum die design requires regularly changed according to the profile changes. Therefore, it needs to predict optimum parameters to assist in the process of aluminum profile extrusion. This paper presents the redesign process using adaptive method. In this case, CBR & ANN method are combined and development. The CBR uses for die feature adaptation; whereas the ANN is used for parameter adaptation and prediction to a new profile and die design. The actual production yield is given and the ANN will find the best size of billet length in order to receive the maximum yield.

System Feature

Multi-gates are often used in the die-casting die design to provide proper feed of the molten metal to the cavity for obtaining a sound casting. Although a number of systems for design of gating-systems are available they do not help much to design multi-gates. A computer aided system for gating-system for die-casting die-design with multi-gates is proposed in this paper. The proposed system helps to generate parameters of the multi-cavity die taking into account a multitude of factors, such as part design, material properties, process data and die-casting machine information. The parameters so generated are applied on selected gating-system feature existing in the library to complete the design of gating-system. The system generated results for industrial case-study parts are in tandem with the industry practices. The proposed system would greatly help bridge the existing gaps between design and manufacturing for die-casting die-design.

In the process of die-casting die design, the die castings should be usually left in the moving die in order to design ejecting mechanism conveniently when open mould. For the special structure of die castings, when lateral side core-pulling mechanism and larger wrapping force on the fixed-die core than on the moving-die core are required, the time-lapse core-pulling mechanism with side slide block can be adopted, which can make die castings left in the moving-die after open mould, and assure die castings production to do successfully. Time-lapse core-pulling mechanism with side slide block is ingenious and simple, and doesn’t increase the production cost of die casting die, and has certain reference value to the design of it.
