[0023] See also Figure 1-Figure 4This embodiment provides a precision investment casting mold, including a base 1, a casting device 2 is provided on the base 1, and the casting device 2 includes a mold 25, the mold 25 is fixedly connected to the top of the base 1, and a baffle 26 is movably passed through the bottom of the mold 25. A support plate 27 is fixedly connected to the right side of the base 1, and a first hydraulic cylinder 28 is fixedly connected to the top of the support plate 27. The output end of the first hydraulic cylinder 28 is fixedly connected to the right side of the baffle 26. The base 1 provides a stable support structure to ensure that the entire mold 25 will not be displaced or deformed during operation. The casting device 2 is provided on the base 1, and the required casting is formed using the casting mold 25. The movable design of the baffle 26 allows the casting to be demolded smoothly, and at the same time, the baffle 26 can be raised and lowered by the control of the first hydraulic cylinder 28, thereby effectively controlling the outflow of the casting and ensuring the smoothness and precision of the casting process. The top of the base 1 is fixedly connected to a fixed rod 21. The top of the fixed rod 21 is fixedly connected to a top plate 22. The top of the top plate 22 is fixedly connected to a second hydraulic cylinder 23. The bottom of the output end of the second hydraulic cylinder 23 is fixedly connected to a cover plate 24. The cover plate 24 is cast in an integrated manner, improving its integrity. There are no internal joints, so there are no weak points at the joints. It does not require assembly and can be directly installed. This facilitates manufacturing and maintenance. The number of parts and steps in the assembly process is reduced, reducing assembly costs and time. The number of connection points and joints is reduced, reducing the risk of looseness or failure between parts, enhancing the structural strength and stability of the entire component, and improving the long-term service life of the product. The fixed rod 21, through its connection with the base 1, provides the vertical support required for the mold 25. The top plate 22 not only enhances the stability of the overall structure, but also accommodates the second hydraulic cylinder 23, which is responsible for driving the lifting and lowering of the cover plate 24 to achieve a closed and sealed mold 25 during the casting process and prevent the casting material from overflowing. This design also allows the cover plate 24 to be quickly opened after casting is completed to facilitate the removal of the casting, improving work efficiency. The cover plate 24 is slidably connected to the outer wall of the fixed rod 21. The cover plate 24 is slidably connected to the outer wall of the fixed rod 21, providing a flexible opening and closing method. The sliding connection design means that the cover plate 24 does not take up additional space when opened, which is convenient for quick operation. In addition, this design also reduces mechanical wear and extends the service life. The operator can quickly and accurately adjust the opening degree of the cover plate 24 by manually or automatically controlling the hydraulic system, thereby achieving fine control of the casting process. A rack 29 is fixedly connected to the front of the baffle 26. The rack 29 fixedly connected to the front of the baffle 26 enhances the functionality of the baffle and realizes precise positioning and control of the baffle 26. When the first hydraulic cylinder 28 is actuated, the combination of the rack 29 and the baffle 26 can provide a greater operating torque, thereby ensuring the rapid opening and closing of the baffle 26 and improving casting efficiency.A rotating rod 210 is rotatably connected to the top of the inner wall of the base 1 via a bearing. A circular gear 211 is fixed to the outer wall of the rotating rod 210, and a knocking block 212 is also fixed to the outer wall of the rotating rod 210. The knocking block 212 is designed to apply impact force to the casting when needed, promoting demolding or crushing of the casting, thereby effectively improving production efficiency. This multifunctional design makes the mold more adaptable to different casting processes. The rack 29 and the circular gear 211 mesh with each other. The meshing relationship between the rack 29 and the circular gear 211 forms an effective power transmission system. When the first hydraulic cylinder 28 acts on the baffle 26 through the rack 29, the circular gear 211 can respond quickly, making the movement of the baffle 26 more precise and efficient. This design not only improves the reliability of the mold 25 operation, but also optimizes the stability and consistency of the casting process. In addition, the meshing of the rack 29 and the circular gear 211 provides higher transmission efficiency, reduces energy loss, and ensures the long-term operation of the mold.
[0024] When the above-mentioned equipment is used, raw materials are added from the mold 25, and the second hydraulic cylinder 23 is started. The second hydraulic cylinder 23 drives the cover plate 24 to descend and cover the top of the mold 25. After the workpiece processing is completed, the first hydraulic cylinder 28 is started. The first hydraulic cylinder 28 drives the baffle 26 to move to the right, and the baffle 26 drives the rack 29 to move to the right. The rack 29 drives the circular gear 211 to rotate, and the circular gear 211 drives the rotating rod 210 to rotate. The rotating rod 210 drives the knocking block 212 to rotate to knock on the outer wall of the mold 25 to assist in demolding. The introduction of mechanical knocking can effectively loosen the workpiece and promote its smooth removal from the mold, thereby avoiding the difficulty of removal due to gap problems.
[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
