Research and Practice of Producing Thin-Walled Complex Cavity Glove Mold Based on Semi-Solid Die Casting with Uniformly Accelerated Charging Barrel Inoculation
With the global demand for energy conservation and emission reduction,carbon peaking,carbon neutrality,the lightening and greening of components in all industries has become an inevitable development path.The glove models required for producing medical rubber and nitrile gloves have always been made of ceramic materials.Although they can meet functional requirements,but have disadvantages such as high energy consumption,easy damage,and no recycling.Switching to easily recyclable metal materials has become a research hotspot,and aluminum alloys have become the preferred choice for the research due to their lightweight.Due to the characteristics of thin-walled and complex inner cavities of the hand mold components,and being necessary to weld with the extrusion forming parts,and the cost of using aluminum profiles for stamping preparation is high.Ordinary die-casting has difficulties in forming complex inner cavities and the casting cannot be welded.In this study,based on the self-developed uniformly accelerated charging barrel inoculation semi-solid die-casting technology,through numerical simulation analysis optimizing the die-casting process,and applying the optimized resin-bonded sand core,the aluminum alloy glove model die castings with complex cavity have been successfully prepared.The developed products meet the project requirements and provide excellent technical examples and references for the research and development of complex cavity die-casting parts.
