Footwear industry,the rapid development of the market and the demand for diversifiedfootwear products,shoe mold market is also increasingly to the small batch,rapid,high-precision direction.Shoe mode of rapid design and manufacturing technology is to seize the key to the footwear market.The research of this paper mainly focuses on the rapid design and manufacturing of shoe mold.In this paper,a design method based on the characteristics of injection molding sole is proposed,and a design method based on reverse engineering and forward drawing is proposed.Using the laser three-dimensional scanning device to collect the shoe pattern data,according to the data reverse design of high-precision three-dimensional model,get the surface smooth,complete texture of the shoe pattern mold.The final shoe modulus and the original grid data comparison,the maximum absolute error of 0.3mm.In this paper,injection molded sole mold as an example of a series of precision modeling and casting experiments.The advantages and disadvantages of four methods,such as precision cast gypsum,phosphate embedding material,wax loss transfer coating sand type and graphite type,are explored in terms of surface roughness and dimensional precision of precision forming.Gypsum method was used to study the stomatal distribution after gypsum solidification.The surface precision was compared with the direct engraving method and the silicone method.The embedding material modeling method was improved on the basis of the traditional process.The method of transferring paint is combined with the lost wax shape to obtain the sand type with high precision coating layer on the surface.Graphite method uses graphite as casting material,studied the design and processing of graphite and casting process,the surface roughness of 1.2μm castings to meet the requirements of the shoe mold accuracy of 1.6μm. |
