Support Pillars and Stop Pins

Support Pillars

S .A .E . 1040 Steel
Pillar height (C dimension) is finished flat and parallel .
Support pillars should be used liberally since they greatly increase
the capacity of the die to support the projected area of the cavities,
runner and sprue . By providing additional support, they prevent
deflection of the die . The absolute necessity of using support pillars
is demonstrated by using standard strength of materials formulas .
For example, an 11 /8 x 15" die without support pillars and with a
7
maximum permissible load on the support plate, will permit 14 square
inches of cavity area without deflecting enough to cause flash . The use
of one row of support pillars on center will quadruple this permissible
cavity area to 56 square inches . Two rows will give nine times the area
or 126 square inches . Please refer to the drawings below .
