Definitions

  • the invention relates to the use of a pre-tempered tool steel for the Production of molds for plastic parts, in particular for matrices with large ones Dimensions.
  • Plastic molds for spraying or pressing plastic parts always exist from two halves, a die and the core part.
  • the surface quality of the plastic part is essentially determined by the quality of the matrix material.
  • the working hardness of the mold steel of about 30-40 HRC is already by tempering the rolled or forged blank at steel manufacturers adjusted (pre-tempered plastic mold steel).
  • Molds for plastics processing are today predominantly made of steels Material number. 1.2311 and 1.2738 and made from AISI P 20 (Chemical Analyzes see Table 1).
  • EP 0 709 481 B1 describes a steel for the type in question Application proposed that has certain levels of boron, the hardenability to increase, with aluminum and titanium to shield the borer Nitrogen must be added.
  • boron for improvement
  • the hardenability leads to non-reproducible at larger diameters Results, i. undefined hardening, especially in the core area.
  • DE 195 33 229 C1 describes the use of a similar steel for Compressed gas tank, DE 37 28 476 C1 for the production of pipes for door reinforcement.
  • the object of the invention is a tool steel for plastic molds to create, even with large diameters high core hardness without qualitative Disadvantages enabled.
  • the mold steel is without risk of cracking in water or Polymer curable, has only low segregations and a high degree of purity and is very high due to the higher tempering temperature after the heat treatment homogeneous and low in residual stress.
  • a sulfur content of up to 0.15 Weight percent be provided, but usually one is to ensure a high degree of purity, the sulfur content as well as to keep phosphorus content as low as possible, for example S ⁇ 0.005% and / or P ⁇ 0.02%.
  • the improved temper resistance is set by higher additions of molybdenum (0.5% instead of about 0.20% at 1.2738) and vanadium (0.1% versus no vanadium at 1.2738).
  • molybdenum 0.5% instead of about 0.20% at 1.27308
  • vanadium 0.1% versus no vanadium at 1.2738.
  • the content of sulfur on about 0.002% limited.
