5.3.5.2 Mechanical Design
The cooling channels should be as close to the surface of the mold as possible so that heat
can flow out of the melt in the shortest time possible.
Figure 5.50 Geometry for the mechanical design of cooling channels
However, the strength of the mold material sets a limit to the distance between the cooling
channel and the mold surface. Taking the strength of the mold material into account, the
allowable distance d (Figure 5.50) was calculated by [27] on the basis of the following
equations:
where
p = mold pressure N/mm 2
/, d - distances mm, see Figure 5.50
E = tensile modulus N/mm 2
G = shear modulus N/mm 2
