Problems solved by technology
[0002] The known casting method is to use the casting model to extrude and print the mold cavity in the sand casting pit (or sand casting box culvert), then pour the molten metal (copper, aluminum, iron, etc.) into the mold cavity to cool, and cast Although the quality of the casting sand does not melt and stick to the surface of the casting during the solidification process of the casting, the casting sand can be easily removed from the casting, but the material characteristics of the sand are highly independent and unconnected, but it also causes the mold cavity of the casting sand The reason for the low stability is that the casting failure rate is high, and the surface of the sandy mold cavity is rough. In this way, the surface of the cast casting is not delicate, and the smoothness requirement is also difficult.

Embodiment Construction
[0014] A casting method that can obtain fine castings, as shown in Figure 1, firstly, the slurry is taken out from the slurry tank 10 storing the slurry by means of equipment transportation, and then the slurry is heated, baked and stirred by a baking mixer 11 to dilute the slurry moisture content, to obtain the clay material during model making;
[0015] The program of model making is to fill the clay into the model mold 12, and with the power of the hydraulic molding machine 13, the clay is pressurized into a clay model with a mold cavity; because the clay is pressurized in the mould, its Most of the remaining moisture will be eliminated during the extrusion process, so that the clay can be molded into a compact and strong clay model according to the shape of the mold, and according to the difference in the size and structure of the casting , the clay model can be divided into a plurality of block models to make and assemble; and the model holder 14 provides the loading and ...

The invention relates to a casting method. Wherein, it comprises that taking off slurry from slurry groove; diluting with water into viscid soil; then filling the soil into mould to be compressed and shape into mode; using the mode carrier to carry and fix the whole mode; heating the mode to reduce the temperature difference between mode and metal fusion liquid; then pouring the fusion metal into the capacity of mode; since the ceramic temperature of mode is higher than the fusion point of metal, cooling the mode, to solidify the metal; releasing the mode, and putting the casting element into soil decompose pool, to remove the soil. The invention can improve the quality of casting element.
Description
technical field [0001] The present invention relates to a casting method that can make the lines, lines, characters, graphics and holes on the surface of castings more detailed or smooth, especially a casting method that can obtain a fine casting surface. Background technique [0002] The known casting method is to use the casting model to extrude and print the mold cavity in the sand casting pit (or sand casting box culvert), and then pour the molten metal (copper, aluminum, iron, etc.) into the mold cavity to cool, and cast Although the quality of the casting sand does not melt and stick to the surface of the casting during the solidification process of the casting, the casting sand can be easily removed from the casting, but the material characteristics of the sand are highly independent and unconnected, but it also causes the mold cavity of the casting sand The reason for the low stability is that the defective rate of castings is high, and the surface of the sandy mold ...
