detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

A kind of rapid prototyping steel mold as shown in Figure 1, is suitable for stamping machine, comprises the base 1 that is fixed with the stamping machine table top, is fixed with lower module 2 on described base 1, and described lower module 2 upper surface is plane and a The side end surface is an arc surface. The lower module 2 is fastened to the base 1 through bolts. A side guard plate 17 is fastened to the arc surface of the base 1 corresponding to the lower module 2 by bolts. The upper part of the rear side of the lower module 2 is fastened with a tailgate 9 by bolts. The rear baffle plate 9 can provide a certain limit effect to avoid the backward displacement of the steel plate when it is leveled and bent.

An upper flat module 3 is provided at the corresponding plane above the lower module 2 , and at least two unloading holes 4 are evenly spaced in the upper flat module 3 . The unloading hole 4 is cylindrical.
