Classification Of Composite Molds

Composite mold refers to a mold structure that completes multiple processes such as blanking and punching in one stroke of the punching machine.
(1) Punching composite molds such as blanking and punching composite molds; cutting and punching composite molds, etc.;
(2) Forming composite molds such as bending composite molds, composite extrusion molds, etc.;
(3) Punching and forming composite molds such as blanking, deep drawing composite molds; punching, flanging composite molds; deep drawing, trimming composite molds; blanking, deep drawing, punching, flanging composite molds, etc.
Compared with other cold stamping die structures, it has the following advantages: (1) The workpiece has better coaxiality, straight surface, and higher dimensional accuracy; (2) High production efficiency, and is not affected by the accuracy of the strip shape Restricted, sometimes scrap corners can also be used for reproduction.
Its disadvantages are: the processing and manufacturing of mold parts is difficult, the cost is high, and the convex and concave molds are easily limited by the minimum wall thickness, so some parts with small inner hole spacing and inner hole and edge spacing are not suitable for use.
Due to the obvious advantages of the composite mold itself, mold companies generally tend to choose the composite mold structure when conditions permit.
