Description

Technical Field

[0001] This utility model relates to the field of core preparation technology, specifically to a wax mold preparation mold containing complex cavities. Background Technology

[0002] The core-making mold contains a multi-angled tubular structure, which is a blind cavity, making it impossible to directly manufacture a core-making mold with multi-angled tubular structures. In actual production, a core-making mold needs to be formed by using a core mold to create the multi-angled tubular structure within the mold. Then, multiple mold pieces, such as the front mold, rear mold, and bottom mold, are combined with the core mold to form an integral mold, i.e., the core-making mold.

[0003] The overall mold is composed of multiple parts. When the segmented mold and the core mold with multi-angle cavities are combined, due to the dimensional accuracy issues of the segmented mold and the core mold, misalignment is prone to occur during assembly, which leads to the segmented mold and the core mold being unable to be assembled as a whole, resulting in low precision of the core preparation mold. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the main purpose of this utility model is to provide a wax mold preparation mold containing a complex cavity. The preparation mold is suspended in a multi-angle cavity through a part of the core mold tube body, which ensures that the core mold and multiple molds are precisely matched separately, ensuring the dimensional accuracy of the soluble core, and thus ensuring the dimensional accuracy of the inner cavity of the later casting.

[0005] To achieve the above objectives, this utility model provides a wax mold preparation mold containing a complex cavity, which includes a first mold body, a second mold body, a third mold body, and a core mold disposed within a multi-angle cavity formed by assembling the first mold body, the second mold body, and the third mold body; the core mold includes multiple tubes distributed at multiple angles, and at least a portion of the tubes in the core mold has the same inner diameter as the corresponding multi-angle cavity for precise fit, while the remaining portion of at least a portion of the tubes is suspended in the multi-angle cavity.

[0006] In some embodiments of this utility model, the inner diameter of at least a portion of the tube body of the core mold is the same as the inner diameter of the port of the multi-angle cavity at the corresponding position for precise fit.

[0007] In some embodiments of this utility model, the length of the pipe body with the same inner diameter at the port is ≥8mm.

[0008] In some embodiments of this utility model, the distance between the suspended part of the tube and the cavity wall of the multi-angle cavity at the corresponding position is proportional to the mold wall thickness corresponding to the suspended part of the tube: d = kx; where k is a proportionality coefficient, d is the distance between the suspended part of the tube and the cavity wall of the multi-angle cavity at the corresponding position, and x is the mold wall thickness.

[0009] In some embodiments of this utility model, at least a portion of the core mold tube passes through the multi-angle cavity and protrudes outside the mold body.

[0010] In some embodiments of this utility model, a first pipe groove is formed on the first mold body, a second pipe groove is formed on the second mold body, and a third pipe groove is formed on the third mold body; the first pipe groove, the second pipe groove, and the third pipe groove together form the multi-angle cavity.

[0011] In some embodiments of this utility model, the multiple tubes of the core mold are divided into X tubes, Y tubes and Z tubes according to the tube extension direction. The Z tube includes Z1 tubes, Z2 tubes, Z3 tubes and Z4 tubes connected to the X tubes and / or the Y tubes. The Z3 tube and the Z4 tube are sleeved in a cavity formed by a portion of the second pipe groove and a portion of the third pipe groove. The first pipe groove and a portion of the third pipe groove and a portion of the second pipe groove form a cavity for sleeved X tubes, Y tubes and Z2 tubes.

[0012] In some embodiments of this utility model, the second mold body is further provided with a through-tube cavity for fitting the Z1 tube body. A portion of the Z1 tube body has the same inner diameter as the through-tube cavity at the corresponding position for precise fit, and the remaining portion of the Z1 tube body is suspended in the through-tube cavity.

[0013] In some embodiments of this utility model, the first mold body is provided with a first positioning protrusion for positioning and assembly with the second mold body.

[0014] In some embodiments of this utility model, the first mold body is provided with a second positioning protrusion for positioning and assembly with the third mold body.

[0015] Advantages of this utility model:

[0016] In a wax mold preparation mold containing complex cavities, at least a portion of the tube body of the core mold has the same inner diameter as the multi-angle cavity at the corresponding position for precise fit, while the remaining portion of the tube body is suspended in the multi-angle cavity. This avoids the problem that the core mold cannot be assembled with the multi-angle cavity in a certain dimension due to the multiple tube bodies distributed at multiple angles.

[0017] The multi-angle distribution of the core mold tube and the multiple mold parts form a multi-dimensional cooperation relationship, ensuring the precise cooperation between the mold parts and the core mold, ensuring the dimensional accuracy of the soluble core, and thus ensuring the dimensional accuracy of the inner cavity of the later casting.

[0033] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0034] As Figures 1-8 shown, a wax mold preparation mold containing complex lumens includes a first mold body 2, a second mold body 3, a third mold body 4 and a core mold 1. The core mold 1 includes a plurality of pipe bodies distributed at multiple angles. The core mold 1 is arranged in the multi-angle lumen formed by the assembly and enclosure of the first mold body 2, the second mold body 3 and the third mold body 4. And at least part of the partial area of at least part of the pipe bodies of the core mold 1 is the same as the inner diameter of the multi-angle lumen at the corresponding position for precise fit, and the remaining partial areas of at least part of the pipe bodies are suspended in the multi-angle lumen.

[0035] Among them, the distance between the suspended part of the pipe body and the lumen wall of the multi-angle lumen at the corresponding position is in a proportional relationship with the wall thickness of the mold corresponding to the suspended part of the pipe body: d = kx;

[0036] In the formula, k is the proportionality coefficient, d is the distance between the suspended part of the pipe body and the lumen wall of the multi-angle lumen at the corresponding position, and x is the wall thickness of the mold.

[0037] In the embodiments of the present invention, when 1 mm ≤ x ≤ 8 mm, 0.4 ≤ k ≤ 0.5; when 8 mm < x ≤ 20 mm, 0.1 ≤ k ≤ 0.15.

[0038] In some embodiments of the present invention, when the wall thickness of the mold corresponding to the suspended part of the pipe body ≤ 10 mm, the distance between the suspended part of the pipe body and the lumen wall of the multi-angle lumen at the corresponding position ≤ 1 mm.

[0039] In some embodiments of the present invention, when the wall thickness of the mold corresponding to the suspended part of the pipe body > 10 mm, the distance between the suspended part of the pipe body and the lumen wall of the multi-angle lumen at the corresponding position ≤ 2 mm.

[0040] In some embodiments of the present invention, when the wall thickness of the mold corresponding to the suspended part of the pipe body ≤ 3 mm, the distance between the suspended part of the pipe body and the lumen wall of the multi-angle lumen at the corresponding position ≤ 0.5 mm.

[0041] In this invention, the method of using a portion of the tube body of the core mold 1 with the same inner diameter as the multi-angle cavity at the corresponding position for precise fit, and the remaining portion of the tube body being suspended in the multi-angle cavity, can avoid the problem that the core mold 1 cannot be assembled with the multi-angle cavity in a certain dimension due to having multiple tube bodies distributed at multiple angles.

[0042] In this invention, the multi-angle distribution of the tube body of the core mold 1 forms a multi-dimensional cooperation relationship with the first mold body, the second mold body, and the third mold body. This ensures that each mold body is precisely matched with the core mold 1, and also utilizes the dimensional accuracy of the core mold 1 to ensure the production of a soluble core and the dimensional accuracy of the inner cavity of the later casting.

[0043] In an embodiment of this utility model, the inner diameter of at least a portion of the tube body of the core mold 1 is the same as the inner diameter of the port of the multi-angle cavity at the corresponding position for precise fit, while the remaining portion of at least a portion of the tube body is suspended in the multi-angle cavity, thus avoiding the defect that the core mold 1 cannot be assembled with the multi-angle cavity in a certain dimension due to having multiple tube bodies distributed at multiple angles.

[0044] As one embodiment of this utility model, the length of the tube body with the same inner diameter at the end of the tube body is ≥8mm to achieve the best precise fit.

[0045] like Figure 1 As shown, the multiple tubes of the core mold 1 are divided into X tube 11, Y tube 12 and Z tube according to the tube extension direction. Among them, the Z tube includes Z1 tube 13, Z2 tube 14, Z3 tube 15 and Z4 tube 16 connected to the X tube and / or Y tube.

[0046] In the embodiments of this utility model, the X-tube, Y-tube, and Z-tube represent the three-dimensional coordinate axes X-axis, Y-axis, and Z-axis where the tube is located, and there is at least one X-tube, Y-tube, and Z-tube.

[0047] In an embodiment of this utility model, Z1 tube 13 is connected to Y tube 12, Z2 tube 14 is connected to X tube 11, and Z1 tube 13 and Z2 tube 14 are arranged in opposite directions.

[0048] In an embodiment of this utility model, tube Z3 15 is connected at the junction of tube X 11 and tube Y 12, and tube Z4 16 is connected at the junction of tube X 11 and tube Y 12.

[0049] In some embodiments of this utility model, the X tube 11 includes the X1 tube and the X2 tube; the Y tube 12 includes the Y1 tube and the Y2 tube.

[0050] Combination Figure 2 and Figure 3As shown, a first pipe groove 21 is formed on the first mold body 2. The core mold 1 is placed in the first pipe groove 21, and part of the pipe body is placed in the first pipe groove 21, and positioning in the X, Y and Z directions is achieved to prevent the core mold 1 from sliding in the first pipe groove 21.

[0051] In some embodiments of this utility model, the X-tube 11, Y-tube 12, and Z2-tube 14 of the core mold 1 are placed correspondingly in the first pipe groove 21 of the first mold body 2. The X-tube 11 and Y-tube 12 respectively cooperate with a portion of the first pipe groove 21 for positioning in the X and Y directions; the Z2-tube 14 cooperates with a portion of the first pipe groove 21 for positioning in the Z direction. At this time, the core mold 1 is positioned in the X, Y, and Z directions by the X-tube 11, Y-tube 12, and Z2-tube 14, preventing the core mold 1 from sliding in the first pipe groove 21.

[0052] In the embodiments of this utility model, the inner diameters at the ports of the X tube 11 and Y tube 12 of the core mold 1 are the same as the inner diameters at the ports of the first pipe groove 21 at the corresponding positions, which is a precision fit.

[0053] The inner diameter of the remaining parts of the X-tube 11 and Y-tube 12 of the core mold 1 is smaller than the inner diameter of the first pipe groove 21 at the corresponding position. After the core mold 1 is assembled into the first pipe groove 21, the X-tube 11 and Y-tube 12 are fixed only through the port of the first pipe groove 21, and the remaining parts of the X-tube 11 and Y-tube 12 are suspended in the first pipe groove 21.

[0054] In an embodiment of this utility model, the inner diameter of the Z2 tube 14 is the same as the inner diameter of the first pipe groove 21 at the corresponding position for precise fit, ensuring accurate positioning in the Z direction.

[0055] Combination Figure 4 and Figure 5 As shown, a third pipe groove 41 is formed on the third mold body 4. The third pipe groove 41 is set in a part of the tube body of the core mold 1, and the third mold body 4 is assembled onto the first mold body 2.

[0056] In some embodiments of this utility model, a portion of the third pipe groove 41 corresponds to a portion of the first pipe groove 21 and surrounds it for connecting the X pipe body 11 and the Y pipe body 12.

[0057] In some embodiments of this utility model, a portion of the third pipe groove 41 is provided corresponding to the Z3 pipe body 15 and the Z4 pipe body 16.

[0058] It is worth mentioning that the inner diameter of the port of the third pipe groove 41 is the same as the inner diameter of the port of the corresponding mating pipe body, which is a precision fit. The inner diameter of the rest of the third pipe groove 41 is larger than the inner diameter of the corresponding mating pipe body. When the third mold body 4 is assembled onto the first mold body 2, the X pipe body 11, Y pipe body 12, and part of the Z pipe body, such as Z3 pipe body 15 and Z4 pipe body 16, are fixed only through the port of the third pipe groove 41. The rest of the X pipe body 11, Y pipe body 12, and part of the Z pipe body are suspended in the third pipe groove 41.

[0059] like Figure 2 As shown, the first mold body 2 is also provided with a second positioning protrusion 23, which is used for positioning and assembly with the third mold body 4, so that the third mold body 4 and the first mold body 2 form a positioning assembly.

[0060] Combination Figure 6 , Figure 7 and Figure 8 As shown, a second pipe groove 31 is formed on the second mold body 3. The second pipe groove 31 is placed corresponding to a part of the tube body of the core mold 1, and the second mold body 3 is assembled onto the first mold body 2. The third mold body 4 is aligned with the second mold body 3, so that a part of the second pipe groove 31 of the second mold body 3 and a part of the third pipe groove 41 of the third mold body 4 surround to form a cavity for sleeved Z tube body, such as the cavity of Z3 tube body 15 and Z4 tube body 16. At the same time, the first pipe groove 21 of the first mold body 2, a part of the third pipe groove 41 and a part of the second pipe groove 31 surround to form a cavity for sleeved X tube body 11, Y tube body 12 and a part of Z tube body, such as Z2 tube body 14.

[0061] As shown in Figure 7, the second mold body 3 is also provided with at least one through-tube cavity 32, which is sleeved on the corresponding Z tube body.

[0062] As one embodiment of this utility model, the second mold body 3 is provided with a through-tube cavity 32 for sleeved Z1 tube body 13.

[0063] A portion of the Z1 tube body 13 has the same inner diameter as the corresponding sleeve cavity 32 for precise fit, while the remaining portion of the Z1 tube body 13 is suspended in the sleeve cavity 32.

[0064] It is worth mentioning that the inner diameter of the port of the second pipe groove 31 of the second mold body 3 is the same as the inner diameter of the port of the corresponding mating pipe body, which is a precision fit. The inner diameter of the rest of the second pipe groove 31 is larger than the inner diameter of the corresponding mating pipe body. When the second mold body 3 is assembled onto the first mold body 2, only the X pipe body 11, Y pipe body 12, and part of the Z pipe body, such as Z3 pipe body 15 and Z4 pipe body 16, are fixed through the port of the second pipe groove 31. The remaining parts of the X pipe body 11, Y pipe body 12, and part of the Z pipe body are suspended in the second pipe groove 31.

[0065] In some embodiments of this utility model, the inner diameter of the Z2 tube body 14 is the same as the inner diameter of the second pipe groove 31 at the corresponding position for precise fit.

[0066] It can be understood that the inner diameter of tube 14 of Z2 is the same as the inner diameter of the multi-angle lumen at the corresponding position for precise fit.

[0067] like Figure 8 As shown, at least a portion of the tube of the core mold 1 passes through the multi-angled cavity and protrudes outside the wax model, that is, there is a portion of the tube of the core mold 1 that is exposed outside the wax model.

[0068] like Figure 2 As shown, the first mold body 2 is also provided with a first positioning protrusion 22, which is used for positioning and assembly with the second mold body 3, so that the second mold body 3 and the first mold body 2 form a positioning assembly.

[0069] In some embodiments of this utility model, after splicing and assembly, at least part of the splicing seams between the first mold body 2, the second mold body 3, and the third mold body 4 are sealed and connected together.
