Cement-based Applied Research In The Field Of Mold In Stamping

Mold manufacturing industry is one of the requirements of a high-tech industry,with good market prospects, a huge potential economic benefits. Mold is one of thelargest automotive production mold products, but it’s a long processing cycle, limitingthe rate of replacement of new models. Mold production cycle is shortened to improveproduct competitiveness in the market a powerful tool. In addition, lower tooling costsis one of the important means to improve the economic efficiency of enterprises.Therefore, the development of new and economical mold material, shortening theproduction cycle is the trend of automotive mold mold to move forward, is a valuableand practical materials processing industries use significant issue.Cement base is one of the widely used civil engineering materials, lower rawmaterial costs and a huge number. In recent years, cement-based material properties andformability of research has been very mature, and its applications continue to expandand grow. The main contents of this paper is to cement base for rapid moldmanufacturing, production of cement-based rapid tooling, the mold is limited strength,not a substitute for high-strength steel mold, but it has easy to shape, rapid prototyping,low cost, Therefore, as the preform mold. But whether it’s strength had reached apre-mold strength requirements, which are the focus of this study. If it reaches apre-formed mold strength requirements, then it’s very good prospects, market economyis quite broad.This paper highlights include the following aspects:①stretch material selected to determine the tensile pieces of rough size,stretching process parameters (such as tensile strength parameters, the tensile modulusgap, etc.) and cement-based mold (upper and lower mold) size. Combined withorthogonal design drawing parameters to determine the final parameters of the mold.②According to the basic dimensions of cement-based mold, mold developedcement-based three-dimensional modeling, namely pouring cement base type box.Pouring cement-based three-frame of the development plan, elect the mold box withfeasibility. Then determine the ratio of cement-based, and finally made out ofcement-based mold (upper and lower mold).③Quality control and testing：cement-based rapid tooling: First, in the pressmeasure the strength of cement-based specimens, and then cement-based die mounted on a hydraulic machine to detect its press formability, propose improvement measuresand programs by analyzing stampings.④arc spraying technology based on cement-based mold surface optimization, andfinally die mounted on a cement base hydraulic test its formability.
