Abstract
Current the die face design are based on the expert experiences and trial and error method. The process time may be long, so that less competition on the market. Therefore, speeding up the development time for the die face design is a crucial issue for the car industry.
This research is divided into two sections, the design principles and construction tools for the die face. Narrative parameters of the die face design of the drawing mold are mostly considered on the general literature reviews, but die face design on the full mould is less consideration, such as trimming, restriking mould. This article summarized all design principles of the die face design from the manufacturing factorys and literatures.
On the construction tools of the die face, the software Spring Solid CAD system is used for the developing platform which is written by Java language. In this paper, some existed software systems such as UG, Dynavista, PAM-STAMP, are used for comparisons.
This paper proposes the automatic construction wireframes for the addendum design instead of manually input a single section of the existed addendum modeling tools, such as the Dynavista. Trimming mould is considered for the construction of section profile for the addendum designs, and the guide curves is also used for the adjustment of the appearance of the die face in order to reduce the building time of the trial and error method. The paper proposes the calculation of the trimming contour for the complex geometric shapes and gives some comparisons with the software system Dynavista.
