The mold design/manufacturing plays a crucial role in the development of high-volume mold-injected, pressed, and/or formed products. A mold fabrication consists of a set of sub-processes and usually takes several months to complete its design and production. Due to the shortening of product lifecycle, the sequence of process execution has to be reengineered to improve its efficiency. This resea...

This paper describes a feature-based approach to automated design of multi-piece sacrificial molds. We use multi-piece sacrificial molds to create complex 3D polymer/ceramic parts. Multipiece molds refer to molds that contain more than two mold components or subassemblies. Our methodology has the following three benefits over the state-of-the-art. First, by using multi-piece molds we can create...

Molten metal meniscus profile and mold flux channel width were measured under high frequency magnetic field by model experiments, then the dynamic pressure in mold flux channel were calculated during one mold oscillation period. It is found that the high frequency magnetic field can decrease the dynamic pressure greatly, which may be one mechanism of improving the billets surface quality by the...

Mold design can be a difficult, time-consuming process. Determining how to split a mold cavity into multiple mold pieces (e.g., core, cavity) manually can be a tedious process. This paper focuses on the mold construction step of the automated mold design process. By investigating glue operations and its relations with parting faces, an approach based on a new reverse glue operation is presented...

This paper presents a parametric design system for 3D tire mold production. Tire grooves commonly used in the current industry are classified according to their modeling procedures, and the design parameters for each groove type are characterized. The result serves as a foundation for standardization of the tire mold design. The presented system simplifies the construction of 3D groove surfaces...
