Embodiment 1
[0020] refer to figure 1 As shown, the present invention discloses a method of utilizing water-soluble wax to make a hollow wax model, the method comprising the following steps:
[0021] a, make the water-soluble wax core original model, make the water-soluble wax core original model according to the shape and weight requirements of the workpiece to be cast, the material of the water-soluble wax core original model is copper, and the water-soluble wax core original model is a copper plate, and the The outer dimension of the water-soluble wax core template is made according to the wall thickness of the workpiece. If the wall thickness of the workpiece is 1mm, the outer dimension of the water-soluble wax core template needs to be manually repaired by 1mm;
[0022] b. Mold making: put the copper plate or silver plate in the aluminum shell, pour the melted tin alloy liquid into the aluminum shell, and after the tin alloy liquid solidifies, open the mold to get the water-soluble wa...
Embodiment 2
[0028] refer to figure 1 As shown, the present invention discloses a method of utilizing water-soluble wax to make a hollow wax model, the method comprising the following steps:
[0029] a, make the water-soluble wax core original model, make the water-soluble wax core original model according to the shape and weight requirements of the workpiece to be cast, the material of the water-soluble wax core original model is copper, and the water-soluble wax core original model is a copper plate, and the The peripheral dimension of the water-soluble wax core template is made according to the wall thickness of the workpiece, and the wall thickness of the workpiece is 1.5mm, so the peripheral dimension of the water-soluble wax core template needs to be manually repaired and removed by 1.5mm;
[0030] b. Mold making: put the copper plate or silver plate in the aluminum shell, pour the melted tin alloy liquid into the aluminum shell, and after the tin alloy liquid solidifies, open the mo...
