Development of Semi-Solid Die Casting Product Design and Die Design Technology for Aluminium Alloy Clamp

Abstract

Semi-solid slurry has significantly higher viscosity than liquid metal. This character of fluidity makes product design and die design, such as gating system, overflow and venting system, be different between these two die casting processes. In the present paper, taking a clamp product as an example, analyses the product optimization and die design by comparing the experimental and computational numerical simulation results. For the clamp, product structure is designed to be suitable for characters of SSM die casting process. The gating system is designed to be uniform variation of thickness, making the cross-sectional area uniformly reduce from the biscuit to the gate. This design ensures semi-solid metal slurry to fill die cavity from thick wall to thin wall. Gate position is designed at the thickest location, the gate shape of semi-solid die casting is set to be much bigger than traditional liquid casting. A good filling behaviour can be achieved by aforementioned all these design principles and it will be helpful to the intensification of pressure feeding after filling.

Current Progress in Rheoforming of Wrought Aluminum Alloys: A Review

“…With a continuous deep development of the artificial intelligence application technology, the highly integrated design and intelligent control of the rheoforming system is the shape of things to come. Special dies and moulds for rheoforming have been designed to enhance the mechanical properties while reducing the cost [140][141][142][143]. Moreover, even though the rheoforming of wrought Al alloy can offer considerable cost saving, high performance, and complex struture of parts, it is a quite long process to redesign a new part for rheofoming to replace the original product while meeting the acutual needs of industry, as displayed in Figure 12.…”
