Dalian stamping die punch manufacturing: according to the various dimensions provided by the model drawings, select high-quality wood to make punch model. The dimensional accuracy of the model requires two precision of wood pattern. The Rz value of the surface roughness is less than 10 m when the wood surface is painted. The draft angle is 1 degrees.
Concave mold manufacturing: Concave mold manufacturing is to paste a layer of lead on the working surface of the punch which is equal to the thickness of the product parts to produce the gap between the convex and the four. The surface of the lead skin should be sprayed so that the roughness of the concave surface after casting is small. The cavity model is made of plaster.
I n order to separate the convex and concave mold models easily when casting gypsum, a layer of mold release agent (such as polystyrene solution of toluene) should be sprayed on the parting surface. After casting, the plaster mold should be dryness, and then demolding. Spray paint on the surface of the cavity and parting surface.
