PURPOSE:To shorten the production period and to reduce the production cost of a titled press die by flame-spraying a self-fluxing alloy into the surface of a flame spraying model, remelting the alloy again and then backing the model surface of the flame spraying layer from the back of the model surface. CONSTITUTION:A fense 3 is set up on the external periphery of a basic model 2 and Shaw slurry is allowed to flow into the fense 3 and solidified. The hardened Shaw slurry 4 is removed from the basic model 2 and the fense 3 and burned in a burning furnace to make a ceramic die 4a. Water glass 5 is applied and impregnated into the surface of the ceramic die 4a to form a flame spraying model 6. The self-fluxing alloy is flame-sprayed on the model surface of the model 6 to form the flame spraying layer 7, which is remelted in the furnace again. After completing the remelting of the flame spraying model 6, a backing material 8 is opposed to the back of the model surface of the flame spraying layer 7 and a synthetic resin 9 is injected to the gap between the model surface and the backing material to fix them and after fixing the flame spraying model 6 is removed to complete a press die. |
