Technical Field

[0001] The utility model relates to the technical field of high-temperature alloy directional solidification, in particular to a universal single crystal test rod casting die assembly tool. Background Art

[0002] In the field of single crystal casting manufacturing, especially in the production of single crystal test bars and blade castings, the combination of a crystal selector and the wax mold of the casting is a critical step. Currently, most tooling equipment on the market faces the problem of a narrow range of applicability. These tools are often only designed for parts of specific sizes and lack sufficient flexibility. For single crystal test bars and blade castings of different sizes or shapes, production personnel may need to replace tooling components or use completely different tooling, which not only increases production costs but also seriously affects production efficiency.

[0003] Most existing tooling can only accommodate a limited range of part sizes. Newly developed or specially sized single crystal test bars and blade castings often require custom tooling, increasing time and cost. Some tooling is complex, requiring frequent component replacements and inconvenient operation, increasing worker workload and potentially leading to product quality issues due to improper operation. Furthermore, during the assembly process, it is difficult to ensure precise alignment between the selector and the casting, affecting the product's grain orientation and ultimate performance.

[0004] Therefore, the tooling equipment in the existing technology has obvious deficiencies in versatility, ease of operation, production efficiency and product quality control. Developing a universal tooling that can overcome the above-mentioned defects, has wide applicability, and can quickly and accurately complete the combination of single crystal test rods and blade casting wax molds of various sizes is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0007] Preferably, a positioning pin is provided between the crystal selector tray and the upper cover plate, and the two are closed and positioned by the positioning pin.

[0008] Furthermore, the test rod mounting platform includes an X-axis guide rail, and mounting columns are respectively provided on the left and right sides of the X-axis guide rail. The mounting columns can move left and right along the X-axis guide rail. A tray rack is provided in the middle of the mounting columns, and the tray rack is used to place the test rod products.

[0009] Preferably, scales are provided on the X-axis guide rail and the mounting column.

[0010] Furthermore, a height positioning slider is provided on the erection column, and a height positioning beam is extended toward the center of the height positioning slider.

[0011] Preferably, the tray rack is composed of a plurality of long strips of plates, with gaps left between the plates. The left and right tray racks are movable inward, and the plates can be staggered and merged through the gaps left.

[0012] Furthermore, the device also includes a positioning block, which is arranged in the middle of the X-axis guide rail and is used to assist in centering the entire device during operation.

In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0018] like Figure 1 As shown, the utility model is a universal single crystal test rod casting die assembly tool, which includes a base 1, a crystal selector 2 and a test rod mounting platform 3.

[0019] The base 1 is the foundation of the entire tooling and is used to support the crystal selector 2 and the test rod mounting table 3.

[0020] The crystal selector 2 is located at the front end of the base 1 and includes a Y-axis guide rail 21 with a pillar 22 on each side. A crystal selector tray 23 is mounted between the two pillars 22 and can move up and down along the pillars 22. The crystal selector tray 23 is equipped with an upper cover 24. Semicircular grooves are defined in the middle of the closed area between the crystal selector tray 23 and the upper cover 24. When the two are closed, these grooves together form a crystal selector positioning slot 25 for the precise placement of the seeding segment.

[0021] In this embodiment, a positioning pin 26 is further provided between the crystal selector tray 23 and the upper cover plate 24 to enhance stability during closing.

[0022] There are two test rod mounting platforms 3, which are respectively arranged in the middle and rear parts of the base 1, including an X-axis guide rail 31. A mounting column 32 is provided on each side of the X-axis guide rail 31. The mounting column 32 can move left and right along the X-axis guide rail 31. A tray rack 33 is installed in the middle of the mounting column 32 for stably placing the test rod products. The mounting column 32 is also equipped with a height positioning slider 34. The height positioning slider 34 extends a height positioning beam 35 toward the center to facilitate precise height adjustment. The tray rack 33 is composed of several long strips of plate members, with gaps between the plates. When the tray racks 33 on the left and right sides move inward, the plates can be staggered and merged through these gaps to accommodate test rod products of different sizes.

[0023] In this embodiment, the device further includes a positioning block 4, which is arranged in the middle of the X-axis guide rail 31 and is used to provide an auxiliary centering function during the operation of the entire device.

[0024] Specific steps:

[0025] First, adjust the four mounting columns 32 with tray racks 33 according to the diameter of the test bar product. Starting from the centerline zero point, move the two tray racks 33 in opposite directions along the X-axis guide 31 by a distance corresponding to the radius of the test bar product. This distance can be precisely determined using the scale on the side of the X-axis guide 31. Next, place the test bar product on the mounting columns 32 with tray racks 33, and adjust the height of the test bar radius using the scale on the side of the mounting columns 32. Use a height gauge placed on the side of the positioning block 4 to determine the center of the test bar. Then, secure all movable components.

[0026] Next, place the seeding section of the crystal selector 2 into the crystal selector positioning groove 25 of the crystal selector tray 23, and place the upper cover plate 24 on the crystal selector tray 23 and fix it with the positioning pins 26. Then, move the crystal selector tray 23 fixed on the pillar 22 along the Y-axis guide rail 21 and stop moving when it is 2 mm close to the test rod product. Next, move the crystal selector tray 23 along the guide rail on the pillar 22 so that the center of the top plane of the spiral section of the seeding section is flush with the center of the test rod. After that, move the crystal selector tray 23 so that the seeding section contacts the center point of the test rod, and fix all movable devices.

[0027] The above steps determine the position of a specific product and seeding section. Once the device is secure, the test rod and seeding section can be placed on the device for assembly. For different products, simply adjust according to the above steps.

[0028] The above is a detailed introduction to a universal single crystal test rod casting mold assembly provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in several ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
