Die Mold Components Characteristic:
1. Wear resistance
When the blank is plastically deformed in the mold cavity, it both
flows and slides along the surface of the cavity, causing severe
friction between the surface of the cavity and the blank, resulting
in the failure of the mold due to wear. Therefore, the wear
resistance of the material is one of the most basic and important
properties of the mold.
Hardness is the main factor affecting wear resistance. In general,
the higher the hardness of the mold parts, the smaller the amount
of wear and the better the wear resistance. In addition, wear
resistance is also related to the type, quantity, shape, size and
distribution of carbides in the material.
2. Strong toughness
Most of the working conditions of the mold are very bad, and some
often bear a large impact load, which leads to brittle fractures.
In order to prevent sudden brittle fracture of mold parts during
operation, the mold must have high strength and toughness. The
toughness of the mold mainly depends on the carbon content, grain
size and organizational state of the material.
3. Fatigue fracture performance
During the working process of the mold, fatigue fracture is often
caused by the long-term action of cyclic stress. Its forms include
small-energy multiple impact fatigue fracture, tensile fatigue
fracture, contact fatigue fracture and bending fatigue fracture.
The fatigue fracture performance of the mold mainly depends on its
strength, toughness, hardness, and the content of inclusions in the
material.
4. High-temperature performance
When the working temperature of the mold is high, the hardness and
strength will decrease, resulting in early wear of the mold or
plastic deformation and failure. Therefore, the mold material
should have high anti-tempering stability to ensure that the mold
has high hardness and strength at working temperature.
5. Heat and cold fatigue resistance
Some molds are in a state of repeated heating and cooling during
the working process, which causes the surface of the cavity to be
subjected to tension, pressure and stress, causing surface cracking
and peeling, increasing friction, hindering plastic deformation,
and reducing dimensional accuracy, resulting in Mold failure. Hot
and cold fatigue is one of the main forms of failure of hot work
dies, and these dies should have high resistance to cold and heat
fatigue.
6. Corrosion resistance
When some molds such as plastic molds are working, due to the
presence of chlorine, fluorine and other elements in the plastic,
strong corrosive gases such as HCI and HF are decomposed after
heating, which erodes the surface of the mold cavity, increases its
surface roughness, and aggravates wear failure.
