Description

Technical Field

[0001] This utility model relates to the field of casting technology, and more specifically, to a casting equipment. Background Technology

[0002] Casting, as a fundamental metal forming process, is widely used in machinery manufacturing, the automotive industry, aerospace, and other fields. With the increasing demands for casting quality, production efficiency, and automation in the manufacturing industry, traditional casting equipment can no longer meet the needs of modern production. Centrifugal casting technology uses the centrifugal force generated by rotation to fill the mold with molten metal, effectively improving the density and forming quality of the casting, and has become one of the important processes in the production of precision castings.

[0003] In the prior art, Chinese patent CN200620104952.9 (A Centrifugal Casting Equipment) provides a typical centrifugal casting solution. This equipment includes a base, a rotating disk mounted on the base, and a speed recorder mounted on the rotating disk. A retaining ring is fixed to the surface of the rotating disk to secure the mold. A flow channel is also formed on the disk surface, with one end connected to the mold cavity and the other end connected to the pouring cup. While this design can improve the filling capacity of the molten steel, producing castings of various shapes and increasing the mechanical properties of the castings by 15-40% compared to ordinary casting methods, it still suffers from the problem that after casting, manual intervention or additional equipment is usually required to separate the upper mold from the lower mold. This process not only increases labor intensity but may also lead to damage or deformation of the castings, affecting the consistency of product quality. Utility Model Content

[0004] Therefore, in order to solve the problem of inconsistent product quality produced by traditional casting equipment, this utility model provides a casting equipment, the specific technical solution of which is as follows:

[0028] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0029] like Figure 1-2 As shown, a casting device according to one embodiment of the present invention includes a machine base 1, a rotating device 2, a pushing device, and a pouring device 4; the rotating device 2 is used to install the casting mold and drive the casting mold to rotate, and the rotating device 2 is disposed on the machine base 1; the pushing device is disposed on the machine base 1, and when casting is completed, the output end of the pushing device passes through the rotating device 2 and lifts the upper mold of the casting mold; the pouring device 4 is disposed on the machine base 1, and the pouring device 4 is used to pour molten metal into the casting mold.

[0030] The aforementioned casting equipment automatically lifts the upper mold after casting, facilitating the removal of the casting. The coordinated operation of the rotating device 2 and the pouring device 4 ensures uniform distribution and full filling of the molten metal within the mold cavity. The centrifugal force generated by the rotating device 2 forces the molten metal to flow to all parts of the mold, especially complex thin-walled areas, effectively preventing incomplete filling and cold shut defects. Uniform rotation ensures stable contact pressure during solidification, resulting in a smooth and clean casting surface, reducing subsequent machining and material waste. This casting equipment solves the problem of inconsistent product quality in traditional casting equipment.

[0031] like Figure 1-2As shown, in one embodiment, the casting device 4 includes a support column 41, a first platform 42, and a casting mechanism 43; one end of the support column 41 is connected to the machine base 1, and the other end of the support column 41 is connected to the first platform 42; the casting mechanism 43 is disposed on the first platform 42; the casting mechanism 43 includes a casting head 431, a lifting block 432, and a first cylinder 433; one end of the first cylinder 433 is connected to the first platform 42, and the other end of the first cylinder 433 is connected to the lifting block 432; the casting head 431 is disposed on the lifting block 432; the first platform 42 is provided with a first through hole for the casting head 431 to pass through, and the casting head 431 is provided with an inlet pipe 10 communicating with the casting head 431. Thus, by setting up a stable frame consisting of support column 41 and first platform 42, a reliable installation foundation is provided for casting mechanism 43; casting mechanism 43 uses first cylinder 433 to drive lifting block 432, realizing precise lifting movement of casting head 431, so that it can flexibly approach or leave the mold gate.

[0032] like Figure 2 As shown, in one embodiment, the rotating device 2 includes a turntable 21, a first rack 22, a first motor, and a first gear 23. A first through-pipe 8 is provided on the machine base 1, passing through the turntable 21, and the turntable 21 is rotatably connected to the first through-pipe 8. The outer contour of the first rack 22 is annular, and the turntable 21 is mounted on the first rack 22. The turntable 21 is used for mounting the casting mold. The first motor is mounted on the machine base 1, and the first gear 23 is located at the output end of the first motor. The first motor drives the first gear 23 to rotate, and the first gear 23 meshes with the first rack 22. Thus, by employing a transmission method where the first motor drives the gear to mesh with the annular first rack 22, the turntable 21 and the mold mounted on it can rotate smoothly and at a uniform speed, which is crucial for generating stable centrifugal force and ensuring uniform casting quality. Compared to common belt drives, gear and rack drives offer higher transmission accuracy, rigidity, and reliability, avoiding slippage or speed fluctuations, thereby ensuring the stability required by the centrifugal casting process.

[0033] like Figure 3As shown, a groove 5 is provided on the outer surface of the turntable 21. The outer contour of the groove 5 is circular, and the groove 5 is arranged around the central axis of the turntable 21. A shim block 6 is provided on the machine base 1, and a sliding block 7 is provided on the shim block 6. The sliding block 7 is inserted into the groove 5 and slidably connected to the groove 5. Thus, by providing a circular groove 5 on the outer surface of the turntable 21 and providing a matching sliding block 7 on the machine base 1 via the shim block 6, this structure constitutes an effective auxiliary support and guiding mechanism. The sliding block 7 slides within the groove 5, which can significantly enhance the stability of the turntable 21 during high-speed rotation, prevent the turntable 21 from radially running or axially moving, and ensure that the rotation axis is always consistent. This further ensures the stability of the direction and effect of centrifugal force, improves the smoothness and reliability of equipment operation, extends the service life of the equipment, and plays an important auxiliary role in obtaining high-quality castings.

[0034] like Figure 1-2 As shown, the pushing device includes a second cylinder 3 and an ejector pin. The turntable 21 has a second through hole 9 for the ejector pin to pass through. The second cylinder 3 is mounted on the machine base 1, and the ejector pin is located at the output end of the second cylinder 3. The second cylinder 3 drives the ejector pin to reciprocate through the second through hole 9. The second cylinder 3 and the ejector pin cooperate to lift the upper mold of the casting mold. Thus, the second cylinder 3 drives the ejector pin to precisely pass through the second through hole 9 on the turntable 21 to lift the upper mold. This direct pushing method provides sufficient power and rapid, reliable operation. The design of the ejector pin passing under the mold allows it to be concealed when the upper and lower molds are joined, without affecting normal mold closing and centrifugal casting processes; it also allows for accurate mold opening when needed, achieving automated mold ejection. This simple and effective structure solves the problem of molds being difficult to open after centrifugal casting due to negative pressure or residual coating adhesion, greatly facilitating part removal operations.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
