The bottom of the lifting ring for mold removal is embedded into the wooden board layer through the super-strong and tough coating.

[0007] Further, the thickness of the wooden board layer is set to 2-5 mm.

[0008] Still further, the super-strong and tough coating is set to be a polyurea coating evenly sprayed on the outer surface of the wooden board layer.

[0009] Still further, the thickness of the super-strong and tough coating is set to 0.5-2 mm.

[0010] Still further, the material of the lifting ring for mold removal is steel.

[0011] Compared with the prior art, the beneficial technical effects of the utility model are:

[0012] (1) The super-strong and tough coating provided can not only play a role in strengthening the lifting ring for mold removal, ensuring the stability of the installation of the lifting ring for mold removal, but also enable the utility model to have super-strong and tough surface characteristics.

[0013] (2) By providing the foam model, the wooden board layer, the super-strong and tough coating and the lifting ring for mold removal, the utility model has the advantages of light weight, convenient mold removal, moisture-proof, not easy to deform and damage, low manufacturing cost and long service life.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the drawings and embodiments.

[0020] As Figure 1 shown, in this embodiment, a super-strong and tough composite pattern for casting is disclosed, which includes a pattern body 1. An installation groove 2 is provided on the surface of the pattern body 1, and a lifting ring 3 for mold removal is provided in the installation groove 2; the pattern body 1 includes a foam model 11. The outer surface of the foam model 11 is coated with a wooden board layer 12, and the outer surface of the wooden board layer 12 is coated with a super-strong and tough coating 13. The bottom of the lifting ring 3 for mold removal is embedded into the wooden board layer 12 through the super-strong and tough coating 13.

[0021] In this embodiment, the material of the foam model 11 is polystyrene, and the manufacturing method of the foam model 11 can be foam molding or sheet processing molding; during processing, a groove-shaped structure having the same shape as the installation groove 2 is reserved on the surface of the foam model 11; the wooden board layer 12 is closely attached to the outer surface of the foam model 11 by means of gluing, and the thickness of the wooden board layer 12 is set to 2-5 mm, preferably 2.5 mm; the material of the mold lifting ring 3 is steel, and it is a ring structure with a handle. After the wooden board layer 12 is firmly pasted, one or more mold lifting rings 3 are installed according to the size of the mold body 1. During installation, the handle part of the mold lifting ring 3 is embedded in the wooden board layer 12, and it is ensured that the ring of the mold lifting ring 3 is inside the installation groove 2; after the mold lifting ring 3 is installed, the production of the super-strong toughness coating 13 is carried out; the super-strong toughness coating 13 is set as a polyurea coating evenly sprayed on the outer surface of the wooden board layer 12, and the thickness of the super-strong toughness coating 13 is set to 0.5-2 mm, preferably 1 mm; when the polyurea coating dries, the super-strong toughness coating 13 can be obtained. The super-strong toughness coating 13 can not only reinforce the mold lifting ring 3 and ensure the stability of the installation of the mold lifting ring 3, but also enable the present utility model to have super-strong toughness surface characteristics. Through the setting of the above structure, the present utility model has the advantages of light weight, convenient mold lifting, moisture-proof, not easy to deform and damage, low production cost and long service life.

[0022] When the present utility model is in use, it includes the following steps: Step 1: As Figure 2 shown, the mold body 1 is turned over 180°, the side with the mold lifting ring 3 is in contact with the template 4, after the sand box 5 is buckled, the molding sand 6 is filled in the sand box 5; Step 2: As Figure 3 shown, when the molding sand 6 is hardened, the sand box 5 is turned over 180°, the mold body 1 is exposed, and then the mold body 1 is lifted out through the mold lifting ring 3, and a mold cavity for casting can be formed in the molding sand 6.

[0023] The above-described embodiments are only descriptions of the preferred modes of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
