SYSTEMS AND METHODS FOR HYBRID SAND CASTING
A hybrid method of casting a metal product is disclosed. The method includes obtaining a product design, creating a mold insert based on the product design, creating a mold base based on the product design, assembling the mold insert with the mold base to form an assembled mold, casting the metal product with the assembled mold, and post-processing the metal product. In some embodiments, creating a mold insert includes generating printing instructions for a mold insert based on the product design and printing a mold insert configured to mate with a product mold (for example, a mold produced by traditional sand molding processes) based on the printing instructions.
1 .- 36 . (canceled)
37 . A method for creating an assembled mold for casting a product, the method comprising:
receiving product design information for the product, wherein the product design information includes one or more customized features for the product;
creating a mold insert by an additive manufacturing process based on the product design information;
creating a mold base using a casting flask based on the product design information;
mating the mold insert with the mold base to form an assembled mold; and
casting the product using the assembled mold.
38 . The method of claim 37 , wherein the assembled mold comprises a mold cavity configured to cast the product including the one or more customized features.
39 . The method of claim 37 , wherein the one or more customized features of the product comprise one or more of customized text, images, borders, and decorations formed according to a digital file of the product design information.
40 . The method of claim 37 , wherein the mold insert comprises a peripheral insert surface having a draft angle.
41 . The method of claim 40 , wherein the draft angle is between about 0° and about 30°.
42 . The method of claim 37 , wherein the mold base comprises a peripheral recess surface sized and configured to receive the mold insert therein to form the assembled mold, wherein a peripheral recess surface comprises a draft angle configured to mate with a peripheral insert surface of the mold insert.
43 . The method of claim 42 , wherein a depth of the peripheral recess surface substantially corresponds to a depth of the mold insert.
44 . The method of claim 43 , where the depth of the mold insert is between about 0.5 inches and about 1.5 inches.
45 . The method of claim 37 , wherein a mold cavity is formed by one or more surfaces of the mold base and one or more surfaces of the mold insert.
46 . The method of claim 37 , wherein mating the mold insert with the mold base includes placing the mold insert within a mold cavity of the mold base which has previously been formed.
47 . A mold for casting a product, the mold comprising:
a mold insert, produced by an additive manufacturing process; and
a mold base, produced with sand using a casting flask and a molding pattern;
wherein the mold insert is mated with the mold base to form the mold.
48 . The mold of claim 47 , wherein the mold comprises a mold cavity configured to cast the product including one or more customized features.
49 . The mold of claim 48 , wherein the one or more customized features comprise one or more of customized text, images, borders, and decorations.
50 . The mold of claim 48 , wherein the mold cavity is formed by one or more surfaces of the mold base and one or more surfaces of the mold insert.
51 . The mold of claim 47 , wherein the mold insert comprises a peripheral insert surface having a draft angle.
52 . The mold of claim 51 , wherein the draft angle is between about 0° and about 30°.
53 . The mold of claim 47 , wherein the mold base comprises a peripheral recess surface sized and configured to receive the mold insert therein to form the mold, wherein a peripheral recess surface comprises a draft angle configured to mate with a peripheral insert surface of the mold insert.
54 . The mold of claim 53 , wherein a depth of the peripheral recess surface substantially corresponds to a depth of the mold insert.
55 . The mold of claim 54 , where the depth of the mold insert is between about 0.5 inches and about 1.5 inches.
56 . The mold of claim 47 , wherein the mold insert is mated to the mold base by baking the mold base around the mold insert.
