Strength and stiffness of injection mold check

- May 27, 2015 -

In CAD of injection moulds structure, composed of injection mold thickness of various templates, first by injection mold designers determined by experience, when die after all the components are checked.

And injection mold parts (such as various kinds of templates, such as ejector pins, bolts and locking wedge) work intensity and the injection mold working, owing to the high injection pressure in the cavity (usually at higher stresses. Injection mould cavity should have sufficient wall thickness 3.0015 million atmosphere), injection mold to withstand to withstand the high pressure of plastic melt. If the wall thickness is not enough may demonstrate a lack of rigidity, which produces large elastic deformation values; can also be shown as strong enough, namely cavity plastic deformation or rupture.
