Abstract
The present invention relates to a method of making a molding tool comprising a core die and a cavity die. The method comprises (a) providing a first metal deposit comprising one of the cavity die or the core die, the first metal deposit having a die face, (b) providing a spray forming pattern on a portion of the die face of the first metal deposit,(c) spraying metal particles onto the first metal deposit and the spray forming pattern to form a second metal deposit comprising the other of the cavity die or the core die, and (d) removing the spray forming pattern from the first and second metal deposits.
Claims20
A method of making a molding tool comprising a core die and a cavity die, said method comprising:
- (a) providing a first steel deposit comprising one of the cavity die or the core die, the first deposit having a die face;
- (b) forming a spray forming pattern, having a first shape, directly on a portion of the die face of the first deposit;
- (c) spraying steel particles onto the first deposit and the spray forming pattern to form a second steel deposit comprising the other of the cavity die or the core die;
- and
- (d) removing the spray forming pattern from the first and second steel deposits.
A method of making a molding tool comprising a core die, a cavity die and a first cavity having a first shape, said method comprising:
- (a) providing a first deposit comprising one of the cavity die or the core die, the first deposit having a die face;
- (b) forming a casting mold directly on the die face of the first deposit, the casting mold having a second cavity, the second cavity having a second shape which is substantially the same as the first shape;
- (c) pouring liquified spray forming pattern material into the second cavity of the casting mold and solidifying the liquified spray forming pattern material to form a spray forming pattern directly on the first deposit, the spray forming pattern having a third shape which is substantially the same as the, first shape, the spray forming pattern material being selected from the group consisting of metal and ceramic;
- (d) removing the casting mold from the first die;
- (e) spraying carbon steel particles, originating from a sprayable carbon steel material in which the carbon content is in the range of 0.01 to 0.9% by weight, onto the first deposit and the spray forming pattern to form a second deposit made of carbon steel, the second deposit comprising the other of the cavity die or the core die;
- and
- (f) removing the spray forming pattern from the first and second steel deposits.
