Description

Technical Field

[0001] This utility model relates to a tooling for assembling wax patterns in precision investment casting, belonging to the field of tooling technology. Background Technology

[0002] In investment casting, a wax pattern is a mold used to form the cavity of the casting. Its manufacturing process includes injecting wax into the mold to form a wax pattern, then coating the surface of the wax pattern with multiple layers of refractory slurry and sand to form a shell. The desired cavity is formed by dissolving the wax pattern, and the shell is sintered to enhance its strength. Finally, molten metal is poured into the shell. After the metal solidifies and cools, subsequent processing steps such as shell removal and cleaning are performed to obtain a high-precision finished casting. The wax pattern plays a crucial role in investment casting, determining not only the shape and dimensional accuracy of the casting but also directly affecting the final surface quality and... The internal structure and high-quality wax patterns ensure that the castings have high dimensional accuracy and surface finish, thereby reducing the need for subsequent processing. Investment casting wax patterns are widely used in many fields such as aerospace, automotive, shipbuilding, medical devices, and machinery manufacturing. For example, in the aerospace field, they are used to manufacture engine blades and impellers; in the automotive field, they are used to manufacture engine blocks, cylinder heads, turbochargers and other parts. When printing wax patterns, wax pattern splicing is required, which requires a suitable splicing tooling for investment casting wax patterns. However, existing splicing devices are not convenient to fold or store when not in use.

[0003] For example, announcement number CN221639445U describes a jig suitable for assembling wax patterns in precision investment casting. It includes a circular base plate for supporting the jig, with multiple angular grooves evenly spaced in a ring for angular positioning with the jig. The base plate also has multiple radially oriented slots, each containing an outwardly extending guide rail. Locking buckles are slidably connected to the guide rails for securing the workpiece. A main shaft is vertically positioned at the center of the base plate. A caliper gripper is movably mounted on the main shaft, allowing rotation and lifting along it. A caliper is attached to the end of the gripper for measuring the radial dimensions of various parts of the workpiece. This invention features a compact and reasonable structure, convenient operation, and overcomes the problem of poor precision between two workpieces. By using this jig, workpiece positioning, centering, and angular positioning can be achieved, facilitating the precise assembly of two or more workpieces with greater accuracy and improved splicing results.

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.

[0023] Please see Figures 1-6As shown, a tooling suitable for splicing wax models in investment casting precision casting includes a mounting plate 1, a base 2 rotatably mounted on the mounting plate 1, a main shaft 3 rotatably mounted on the base 2, a collar 4 sleeved on the main shaft 3, and a caliper 5 rotatably mounted on the collar 4. The caliper 5 can measure the dimensions of various radial parts, thereby improving the accuracy of splicing. The angle of the caliper 5 can be flexibly adjusted by rotating the base 2. Fixing components 6 for positioning the main shaft 3 are provided on both sides of the base 2. The fixing components 6 can be used to engage the main shaft 3 with the base 2. The caliper 5 is provided with a screw 7, which is slidably engaged with the collar 4. A clamping nut 8 is threaded onto the screw 7. By loosening the clamping nut 8, the caliper 5 can be rotated, thereby facilitating the parallel alignment of the caliper 5 with the main shaft 3. Positioning plates 9 arranged in an array are slidably engaged on the mounting plate 1. The position of the positioning plates 9 can be flexibly adjusted according to the splicing requirements.

[0024] The base 2 has a square hole 10, and the main shaft 3 has positioning grooves 11 on both sides. The fixing component 6 includes a positioning block 601, which is snapped into the square hole 10 and matches the positioning groove 11. A moving rod 602 is connected between the positioning blocks 601. A spring 603 is sleeved on the positioning block 601. The two ends of the spring 603 are fixedly connected to the base 2 and the moving rod 602, respectively. By moving the moving plate, the spring 603 extends and the positioning block 601 moves. When the positioning block 601 moves out of the positioning groove 11, it is convenient for the main shaft 3 to rotate, which makes it convenient to fold the main shaft 3 and the mounting plate 1, thereby saving space and making it convenient to store this splicing tool. The positioning hole 14 is snapped into the positioning groove 11, so that the main shaft 3 is perpendicular to the mounting plate 1.

[0025] The collar 4 has a slotted hole 12. The screw 7 and the collar 4 are slidably engaged through the slotted hole 12. By loosening the clamping nut 8, the screw 7 moves along the slotted hole 12 to adjust the angle of the caliper 5. This allows the caliper 5 to be parallel to the main shaft 3 when not in use, facilitating the storage of this assembly fixture. The mounting plate 1 has a sliding groove 13. The positioning plate 9 and the mounting plate 1 are slidably engaged through the sliding groove 13. The mounting plate 1 and the positioning plate 9 have positioning holes 14. The positioning holes 14 are inserted into the positioning holes. The positioning pin 15 is attached. Removing the positioning pin 15 allows for flexible adjustment of the position of the positioning plate 9, thus facilitating flexible adjustment of the position of the positioning plate 9 according to splicing requirements and improving the applicability of this splicing fixture. The collar 4 and the main shaft 3 are provided with fixing holes 16, and fixing pins 17 are inserted into the fixing holes 16. The collar 4 and the main shaft 3 are fixed by fixing pins 17. By removing the fixing bolts, the position of the collar 4 on the main shaft 3 can be flexibly adjusted, and the height of the caliper 5 can be flexibly adjusted.

[0026] In use, the workpieces to be spliced ​​are snapped into the positioning plate 9, the fixing pin 17 is removed, the collar 4 is adjusted to a suitable position, the fixing pin 17 is inserted into the suitable fixing hole 16, the caliper 5 is adjusted to a suitable height, and the radial dimensions of each workpiece are adjusted using the caliper 5. The positioning pin 15 is removed, the positioning plate 9 is adjusted to a suitable position, and the positioning pin 15 is inserted into the suitable positioning hole 14. When this splicing fixture is not in use, the moving plate is moved, the spring 603 extends, and the positioning block 601 moves. When the positioning block 601 moves out of the positioning groove 11, the main shaft 3 is rotated, and the main shaft 3 and the mounting plate 1 are folded together. The clamping nut 8 is loosened, and the caliper 5 is rotated to make the caliper 5 parallel to the main shaft 3. Thus, this splicing fixture can be folded when not in use, saving space and making it easy to store.
