In the design process of the molding tool, first, the synopsis ground says to hurtle to press the molding tool all after society develop the function in the realm and it of development prospect.Order the design meaning of understand the molding tool.Then carry on the craft analysis of the work piece, then made sure the craft project.Compute the molding tool work part of size business trip, design zero partses of, then request to choose the each standard piece according to the design.Design a total assemble diagram of molding tool finally.The demand computes the blunt pressure in design process, falling to anticipate the dint, the flection dint and push a dint, unload to anticipate the dint.Thus judge whether each parts of molding tool can bear the function of the pressure machine or not.The design of the more important molding tool work spare parts, with this for core of problem, work spare parts of error margin will affect the quantity of make the piece directly.Finally the benefit manufactures to assemble the diagram and the spare parts diagrams in the painting tool AutoCAD, but saved many time. Pass this time design make me not only controled to hurtle the general process of press the molding tool design, the better study is a lot of in the lesson originally up have no knowledge of study.
