Description

Technical Field

[0001] The utility model relates to the field of semi-solid forming dies, in particular to a semi-solid metal cavity forming die. Background Art

[0002] Semi-solid molds are important tools for semi-solid metal processing. Semi-solid metal processing technology is a technology that stirs liquid metal when it solidifies, then obtains a slurry with a solid phase component of about 50% or even higher at a certain cooling rate, and forms the slurry by die casting. There are two main processes for semi-solid die casting: rheoforming process and thixoforming process. The rheoforming process is to feed the liquid metal into a specially designed injection molding barrel, and the spiral device applies shear to cool it into a semi-solid slurry, and then die casting. The thixoforming process is to feed solid metal particles or debris into a spiral injection molding machine, and die-cast the semi-solid metal particles under heating and shearing conditions.

[0003] Therefore, based on the better fluidity of semi-solid materials, semi-solid molds are mostly manufactured by die casting. However, the die-casting head and the cavity are fixed on the upper mold and the lower mold respectively. For molds of different models and different processing requirements, the new mold product needs to produce an upper mold connected to the die-casting head and a lower mold connected to the cavity. This leads to higher mold design and mold manufacturing costs for new products, and there is room for improvement. Summary of the invention
