Definitions

  • the present invention relates to a method for manufacturing a glass molding die that requires precise processing, and particularly relates to a method capable of maintaining the shape of the die with high accuracy.
  • the mold is manufactured by applying electroless Ni—P plating to the surface of a base material made of stainless steel, and then precisely processing this plating layer with a diamond bite.
  • a base material having a thermal expansion coefficient of ⁇ ⁇ _ 6 ⁇ ; ⁇ ⁇ ⁇ ⁇ ⁇ 1 ) is selected, and heat treatment is performed at 400 to 500 ° C after plating. Even if the thermal expansion coefficient of the base material is matched to that of the Ni-P plating layer, volume contraction due to crystallization occurs only in the plating layer during heat treatment, so that a large tensile stress acts on the plating layer. In some cases, cracks occur (see, for example, JP-A-11 157852).
  • the present invention prevents the occurrence of cracks in the surface coating layer at the molding temperature, and also prevents the plastic deformation of the mold, thereby maintaining the shape of the mold with high accuracy. It is an object of the present invention to provide a method for manufacturing a glass mold that can increase the service life. [0007] In order to solve the above problems and achieve the object, the method for producing a glass molding die of the present invention is configured as follows!
  • Carbon is 0.3 wt% or more 2.7 wt% or less, chromium is 13 wt% or less, molybdenum is 0.5 wt% or more and 3 wt% or less, vanadium is 0.1 wt% or more and 5 wt% or less, tungsten is lwt
  • a base material is formed by quenching a steel material to which an additive satisfying at least one of at least 1% and not more than 7wt% is added and tempering at 400 ° C or higher and 650 ° C or lower.
  • a surface coating layer made of an amorphous Ni—P alloy is formed on the surface, and the surface coating layer is changed to a eutectic structure of Ni and Ni P by subjecting it to a heat treatment.
  • Carbon is 0.3 wt% or more 2.7 wt% or less, chromium is 13 wt% or less, molybdenum is 0.5 wt% or more and 3 wt% or less, vanadium is 0.1 wt% or more and 5 wt% or less, tungsten is lwt

  • FIG. 1 is a block diagram showing an outline of a manufacturing process of a glass molding die according to an embodiment of the present invention. Manufacture of a glass mold is performed by the following process.
  • carbon is 0.3 wt% or more and 2.7 wt% or less
  • chromium is 13 wt% or less
  • molybdenum is 0.5 wt% or more and 3 wt% or less
  • vanadium is 0.1 wt% or more and 5 wt% or less. Less than%, use a steel material to which an additive satisfying at least one of tungsten and lwt% or more and 7wt% or less is added.
  • the surface coating layer is prevented from cracking even when high-temperature tempering is performed by using steel having Mo, V, and W added to improve the high-temperature hardness. I have to. This is because a high-temperature tempering force that contains a large amount of retained austenite immediately after quenching changes to a low-carbon martensite and martensite structure.
  • the temperature in the high temperature tempering needs to be 400 to 650 ° C or less. It is not very effective in reducing retained austenite at temperatures lower than 400 ° C. Above 650 ° C, the base material is significantly softened. In addition, it may be possible to perform sub-zero treatment more than high temperature tempering! /. This is because subzero treatment also has the effect of transforming retained austenite to martensite.
  • the surface coating layer is formed using a Ni—P alloy such as Ni—P, Ni—P—B or Ni—P—W. These structures are amorphous or partially amorphous in the plated state, and transform to a fully crystallized mixed structure of Ni and NiP when heated to about 270 ° C or higher.
  • the temperature of the heat treatment needs to be equal to or higher than the use temperature of the mold (that is, the glass forming temperature). This is because, if the temperature is lower than the mold use temperature, dimensional changes occur during use, and the dimensional accuracy of the molded product decreases. If the heat treatment temperature is raised too much, it affects the mating surface, so the upper limit of the heat treatment temperature is about 700 ° C.
  • the C content was set to 0.3 wt% or more and 2.7 wt% or less.
  • the C content is lower than 0.3 wt%, the volume shrinkage of the base material during tempering becomes too small.
  • the C content exceeds 2.7 wt%, adverse effects such as a decrease in toughness that the volume shrinkage of the base material is sufficient will occur.
  • the Cr content was set to 13 wt% or less. This is because when the Cr content exceeds 13 wt%, the retained austenite is decomposed. There are no particular restrictions on the lower limit of the Cr content.
  • Mo was 0.5 wt% or more and 3 wt% or less
  • V was 0.1 wt% or more and 5 wt% or less
  • W force was wt% or more and 7 wt% or less.
  • the amount of these additives is low If it is too high, the high-temperature hardness of the substrate is not sufficient, and plastic deformation may occur due to press pressure. Note that the upper limit is set because the cost increases if the number is increased more than necessary.

The presence or absence of plastic deformation of the material was examined. Table 1 shows the relationship between the base material components, tempering temperature, crack generation rate, and the presence or absence of plastic deformation.
