Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a side mold insulation structure. Background Technology

[0002] In gravity casting, mold design plays a crucial role in casting quality. Traditionally, corner areas are often designed as solid structures due to demolding and structural complexity. However, this design presents several problems: when combined with other mold edges, this area tends to be thinner than others, and external insulation is impossible. This results in inconsistent mold temperatures at the corners, leading to casting defects and affecting the quality of the casting. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a side mold insulation structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a side mold insulation structure, including a side mold body. The side mold body includes a molding surface located on the inner side and splicing end faces located at both ends. A cavity is provided on the side of the side mold body away from the molding surface. A hollow area is opened at the splicing end face, and the hollow area is connected to the cavity.

[0006] Furthermore, the cross-sectional shape of the hollowed-out area follows the shape of part of the outer contour of the spliced ​​end face.

[0007] Furthermore, the distance between the inner wall of the hollowed-out area near the molding surface and the molding surface is at least 10-15mm.

[0008] Furthermore, the side mold body includes an edge line, which is located on the side of the splicing end face away from the forming surface, and the distance between the side of the hollow area away from the forming surface and the splicing end face is 3-5mm.

[0009] Furthermore, it also includes a seal, which is disposed on the mating end face.

[0010] Furthermore, the seal includes an insert, and a step is provided at one end of the hollow area near the mating end face. The shape of the insert matches the mating end face, and part of the insert is located at the step.

[0011] Furthermore, the inner side of the insert is fixed to the step by welding.

[0012] Furthermore, the insert is fixed inside the step, and the insert and the step are interference-fitted.

[0013] The beneficial effects of this utility model are: by opening a hollow area to connect with the cavity, the heat insulation material can be filled into the hollow area, so that the temperature of the two ends and corners of the mold body is consistent with that of other areas, avoiding the occurrence of local cold areas, thereby effectively reducing the occurrence of casting defects.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-2 As shown, a side mold insulation structure includes a side mold body 1, which includes an inner molding surface 6 and two end faces 3. In use, as... Figure 4 As shown, the four side mold bodies 1 are joined together, and the opposite splicing end faces 3 of adjacent side mold bodies 1 are fitted together. A cavity 2 is formed on the side of the side mold body 1 away from the forming surface 6. A hollow area 4 is formed at the splicing end face 3, and the hollow area 4 is connected to the cavity 2. The cavity 2 and the hollow area 4 are filled with thermal insulation material, so that the thermal insulation performance of each position of the side mold body 1 is relatively uniform, and thus the temperature of each position of the side mold body 1 is relatively uniform.

[0021] The specific processing method for the hollow area 4 is as follows: milling is performed on the end face of the splicing end face 3, with the depth direction perpendicular to the splicing end face 3. The milling depth extends to the point where the hollow area 4 is connected to the cavity 2. The milling follows the shape of part of the outer hub of the splicing end face 3, so that the cross-sectional shape of the hollow area 4 conforms to part of the outer contour of the splicing end face 3. The inner wall of the hollow area 4 on the side close to the forming surface 6 conforms to the forming surface 6, and the distance between the two is at least 10-15mm. The side mold body 1 includes the edge line 7, which is located on the side of the splicing end face 3 away from the forming surface 6. The side of the hollow area 4 away from the forming surface 6 is parallel to the splicing end face 3, and the distance between the two is 3-5mm.

[0022] Because the heat insulation performance of the corners of the edge mold body 1 is enhanced, the solidification speed of the molten metal at these locations will not be too fast. There is no need to add wide flow channels at the corners to ensure the fluidity of the metal, thereby avoiding the increased aluminum consumption caused by wide flow channels and reducing the time and difficulty of subsequent machining.

[0023] The structure also includes a sealing element, which is set on the splicing end face 3 to close the hollow area 4, so that each side mold body 1 is a relatively independent individual. The insulation material filled in the side mold body 1 will not enter the adjacent side mold body 1 through the hollow area 4.

[0024] Specifically, the seals include, for example Figure 3 The inlay 8 shown has a step 5 at one end of the hollow area 4 near the splicing end face 3. The hub of the step 5 is 2-3mm larger than the hub of the hollow area 4, and the depth of the step 5 is 5-6mm.

[0025] The shape of the inlay 8 matches the splicing end face 3, and part of the inlay 8 is set at the step 5, thereby closing the hollow area 4.

[0026] The insert 8 can be fixed in a variety of ways. One method is welding, which involves welding the inner side of the insert 8 to the end face of the step 5 to fix the two together, while keeping the end face of the insert 8 flush with the splicing end face 3.

[0027] Another method is a snap-fit, where the insert 8 is directly snapped into the step 5, and the two are fixed together by an interference fit.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
