Technical Field

[0001] This utility model belongs to the field of metal casting technology, and specifically relates to a modular wax mold splicing tool with a tubular cavity. Background Technology

[0002] Investment castings are widely used in aviation, aerospace, shipbuilding and weaponry due to their high dimensional accuracy. For castings with multi-angled tubular structures, the inner cavity is mainly formed by using prefabricated ceramic or metal cores, which are then removed after casting.

[0003] When preparing wax models for castings containing multi-angled cavities, a split wax model is required to facilitate the placement of the core with multi-dimensional tubular bodies within the multi-dimensional cavities of the wax model. The structure of a split wax model is relatively complex, and there are issues with dimensional accuracy during manufacturing. Therefore, misalignment can easily occur during assembly, leading to the inability to precisely assemble the segmented wax model with the core.

[0004] Therefore, this utility model is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a modular wax mold splicing fixture with a cavity. The splicing fixture of this utility model can ensure that the modular wax mold and the core are precisely matched.

[0006] To achieve the above objectives, this utility model proposes a modular wax mold assembly tooling with a cavity, wherein the modular wax molds can be assembled to form a bottom wax mold, a rear wax mold, and a front wax mold with a cavity. The assembly tooling includes a base plate with a fixing ring, a sliding plate slidably connected to the base plate, and a top pressure plate correspondingly connected to the fixing ring.

[0007] The base plate has a fixing ring for mounting the rear wax model, and the top plate and the fixing ring are adapted to fix the front wax model above the rear wax model. The sliding plate is used to place the bottom wax model and to slide the bottom wax model to the splicing position to splice with the rear wax model and the front wax model when the plate is moved.

[0008] The splicing fixture provided by this utility model may also have the following additional technical features:

[0009] In one specific embodiment of this utility model, the base plate is further provided with a plurality of support columns surrounding the fixing ring, the support columns being used to support the pipe groove of the rear wax mold.

[0011] In one specific embodiment of this utility model, the upper surface of the support column is provided with a curved surface that is adapted to and positioned with the pipe groove of the rear wax mold.

[0012] In one specific embodiment of this utility model, the number of support columns is four, and each support column is provided at the end of the pipe groove.

[0013] In one specific embodiment of this utility model, the sliding plate is provided with a positioning block, a support block, and a side baffle on the side of the positioning block away from the fixing ring. The bottom wax mold is positioned by the positioning block and the support block and is adapted to the sliding plate, and is adapted to and spliced ​​with the rear wax mold and the front wax mold by the lateral support force provided by the side baffle.

[0014] In one specific embodiment of this utility model, the base plate is provided with a second slide rail and a slider slidably connected to the second slide rail, and the slide plate is connected to the slider.

[0015] In one specific embodiment of this utility model, there are two second slide rails and two sliders, and the two second slide rails are arranged in parallel.

[0016] In one specific embodiment of this utility model, both ends of the second slide rail are provided with stop blocks, which are used for stopping.

[0030] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0033] like Figure 1-6As shown, this utility model proposes a modular wax mold splicing fixture 5 with a cavity. The modular wax molds can be spliced ​​to form a bottom wax mold 2, a rear wax mold 3, and a front wax mold 4 with a cavity. The splicing fixture 5 includes a base plate 51 with a fixing ring 511, a sliding plate 52 slidably connected to the base plate 51, and a top pressure plate 53 correspondingly connected to the fixing ring 511. The fixing ring 511 of the base plate 51 is used to install the rear wax mold 3. The fitting connection between the top pressure plate 53 and the fixing ring 511 is used to fix the front wax mold 4 above the rear wax mold 3. The sliding plate 52 is used to place the bottom wax mold 2 and to slide the bottom wax mold 2 to the splicing position to splice it with the rear wax mold 3 and the front wax mold 4 by moving it.

[0034] The splicing fixture 5 provided in this embodiment uses a base plate 51 with a fixing ring 511 to fix the rear wax model 3 by fitting and positioning the fixing ring 511 with it. A top pressure plate 53 connected to the fixing ring 511 is then used to press and fix the front wax model 4 above the rear wax model 3, thus splicing the rear wax model 3 with the front wax model 4. A sliding plate 52 slidably connected to the base plate 51 is also provided to slide the bottom wax model 2 to a preset position, thus splicing the bottom wax model 2 with the rear wax model 3 and the front wax model 4, i.e., splicing the segmented wax models. Furthermore, the base plate 51, top pressure plate 53, and sliding plate 52 in the splicing fixture 5 are designed for segmented wax models, which improves the stability of the base plate 51, top pressure plate 53, and sliding plate 52, thereby improving splicing accuracy and efficiency.

[0035] In one specific embodiment of this utility model, the base plate 51 is further provided with a plurality of support columns 512 surrounding the fixing ring 511. The support columns 512 are used to support the pipe groove of the rear wax model 3. By setting the support columns 512 to support the pipe groove, damage to the pipe groove due to excessive force during the splicing process can be avoided, thereby ensuring the smooth progress of the splicing.

[0036] In one specific embodiment of this utility model, a first slide rail is provided on the base plate 51, and a sliding groove is provided at the bottom of the support column 512, which is slidably connected to the first slide rail. This allows for adjustment of the position of the support column 512, enabling it to be used for splicing different segmented wax molds.

[0037] In one specific embodiment of this utility model, the upper surface of the support column 512 is provided with a curved surface that is adapted to and positioned with the pipe groove of the rear wax mold 3. The above-mentioned arrangement can limit the rear wax mold 3 through the support column 512, thereby achieving precise positioning of the rear wax mold 3.

[0038] In one specific embodiment of this utility model, there are four support columns 512, and each support column 512 is provided at the end of the pipe groove.

[0039] In one specific embodiment of this utility model, the sliding plate 52 is provided with a positioning block 55, a support block 54, and a side baffle 56 located on the side of the positioning block 55 away from the fixing ring 511. The bottom wax mold 2 is positioned and adapted to the sliding plate 52 by the positioning block 55 and the support block 54, and is adapted to be spliced ​​with the rear wax mold 3 and the front wax mold 4 by the lateral support force provided by the side baffle 56. Specifically, by setting the positioning block 55 and the support block 54, the bottom wax mold 2 can be positioned, thereby placing it in a preset state for easy splicing. By setting the side baffle 56, a uniform force can be provided to the bottom wax mold 2 to drive it to be tightly connected with the front wax mold 4 and the rear wax mold 3.

[0040] In one specific embodiment of this utility model, a second slide rail 513 and a slider slidably connected to the second slide rail 513 are provided on the base plate 51, and a sliding plate 52 is connected to the slider. Specifically, the sliding plate 52 is connected to the slider by threaded fasteners. The above not only enables the sliding connection between the sliding plate 52 and the base plate 51, but also provides a simple and effective connection structure, thereby further improving the splicing efficiency of the segmented wax mold. In addition, the sliding plate 52 corresponds to the structural setting of the bottom wax mold 2, so the sliding plate 52 can also be replaced because it is connected to the base plate 51 by threaded fasteners, thus making the splicing fixture 5 adaptable to the splicing of different segmented wax molds.

[0041] In one specific embodiment of this utility model, there are two second slide rails 513 and two sliders, with the two second slide rails 513 arranged in parallel. This ensures the balance of the sliding plate 52, thereby allowing the bottom wax mold 2 to be evenly stressed and preventing damage to the wax mold due to uneven stress during assembly.

[0042] In one specific embodiment of this utility model, both ends of the second slide rail 513 are provided with stop blocks for stopping. Specifically, the stop block on the side near the fixing ring 511 is a sliding position indicator, which is set according to the structure of the segmented wax model to indicate that the bottom wax model 2 has slid into place, avoiding excessive sliding and damage to the wax model. The stop ring on the side away from the fixing ring 511 is used to prevent the sliding plate 52 from detaching from the fixing plate. By setting stop blocks that can indicate the completion of splicing, the splicing difficulty can be further reduced, thereby improving the splicing efficiency.

[0043] In one specific embodiment of this utility model, both the fixing ring 511 and the top pressure plate 53 are provided with screw holes, and the top pressure plate 53 is connected to the fixing ring 511 by a screw 57 passing through the screw hole. The above structure not only realizes the connection between the fixing ring 511 and the top pressure plate 53, but also has a simple and effective connection structure, thereby further improving the splicing efficiency of the segmented wax mold.

[0044] In one specific embodiment of this utility model, and / or the fixing ring 511 and the top pressure plate 53 are provided with weight reduction holes. By providing weight reduction holes on the fixing ring 511 and the top pressure plate 53, on the one hand, the weight of the splicing fixture 5 can be reduced, thereby facilitating handling; on the other hand, the gravity applied by the top pressure plate 53 to the front wax model 4 and the rear wax model 3 can be reduced, thereby avoiding damage to the wax model structure.

[0045] The specific steps for assembling segmented wax models using the assembly fixture provided in this embodiment are as follows:

[0046] Fixing the rear wax model 3: The rear wax model 3 is installed on the fixing ring 511 of the base plate 51; wherein the shape of the fixing ring 511 is adapted to the shape of the center hole of the rear wax model 3, so that the rear wax model 3 can be placed on the base plate 51 with the splicing surface facing upward.

[0048] Front wax mold 4 is fixed: the front wax mold 4 is installed on the rear wax mold 3 by the top pressure plate 53, and part of the third pipe groove and part of the second pipe groove 31 surround to form the cavity of the sleeve part of the Z pipe body 13; specifically, the fixing ring 511 is provided with a threaded hole, the top pressure plate 53 is provided with a through hole, and a screw 57 is inserted into the through hole of the top pressure plate 53. The screw 57 passes through the center hole of the rear wax mold 3 and the front wax mold 4 in sequence to connect with the threaded hole on the fixing ring 511, thereby realizing the splicing of the rear wax mold 3 and the front wax mold 4.

[0049] Fixing the bottom wax mold 2: Place the bottom wax mold 2 on the sliding plate 52 and push the sliding plate 52 to connect the bottom wax mold 2 with the rear wax mold 3 and the front wax mold 4, so that the first pipe groove 21, part of the third pipe groove 41 and part of the second pipe groove 31 surround and form a cavity that fits the X tube body 11 and the Z tube body 13. The Z4 tube body 17 is located in the limiting groove of the bottom wax mold 2. Specifically, the base plate 51 is provided with a second slide rail 513 and a slider slidably connected to the second slide rail 513. The sliding plate 52 is connected to the slider to slide relative to each other on the base plate 51. The bottom wax mold 2 is fixed at a preset angle by the positioning block 55, the support block 54 and the side baffle 56 provided on the sliding plate 52.

[0050] During assembly, the first positioning protrusion 22 and the second positioning protrusion 23 on the bottom wax mold 2 are respectively matched and positioned with the positioning holes at the corresponding positions of the front wax mold 4 and the rear wax mold 3.
