Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a cylinder head machining mold frame, including an operating table 1. The operating table 1 serves as the basic support structure of the entire mold frame, providing a stable platform for the installation of other components. It can withstand the forces generated during the operation of each component, ensuring the smooth progress of the entire machining process. A mold blank 2 is fixedly connected to the top of the operating table 1. The mold blank 2 is a key basic part of cylinder head forming, providing a specific spatial shape for subsequent molten metal injection and forming, allowing the molten metal to gradually solidify within its defined range to form the approximate shape of the cylinder head.
[0033] A small water pump 3 is fixedly connected to the top of the control panel 1. The small water pump 3 plays a crucial role in transporting refrigerant. Through its operation, it stably delivers the refrigerant to the subsequent pipelines, providing power support for the cooling process and ensuring the normal flow of refrigerant throughout the refrigeration cycle system. A water inlet hose 4 is fixedly connected to the output end of the small water pump 3. The water inlet hose 4 is made of flexible material and has good sealing properties. It can flexibly connect the small water pump 3 to the three-way pipe 5, effectively transferring the refrigerant and preventing leaks during transport, ensuring a smooth refrigerant transport path.
[0034] A T-connector 5 is fixedly connected to the end of the inlet hose 4 furthest from the small water pump 3. The T-connector 5 plays a crucial role in diverting the refrigerant, distributing it evenly to the two refrigerant tube supports 6 from the small water pump 3. This ensures that both refrigerant tube supports 6 receive sufficient refrigerant for cooling, resulting in a more uniform temperature reduction throughout the entire mold blank 2. Both ends of the T-connector 5 are fixedly connected to refrigerant tube supports 6. The refrigerant tube supports 6 are positioned appropriately within the mold blank 2 and have channels for refrigerant flow. When the refrigerant circulates within them, it quickly absorbs heat from the molten metal within the mold blank 2, accelerating the cooling and solidification of the molten metal, thereby improving the production efficiency of the cylinder head.
[0035] Clamping blocks 7 are fixedly connected to the outer walls of the two refrigeration tube supports 6. The clamping blocks 7 stabilize the position of the refrigeration tube supports 6, firmly fixing them to the inner wall of the mold blank 2. This prevents displacement of the refrigeration tube supports 6 under the influence of refrigerant flow or other external forces, ensuring a continuous and stable cooling effect. The end of the clamping block 7 furthest from the refrigeration tube supports 6 is fixedly connected to the inner wall of the mold blank 2. This connection method forms a relatively stable whole between the refrigeration tube supports 6 and the mold blank 2, ensuring that the refrigeration tube supports 6 can fully exchange heat with the molten liquid inside the mold blank 2 during operation, thus better achieving the cooling function.
[0036] Two refrigerant tube racks 6 are fixedly connected to outlet pipes 8 at their ends furthest from the small water pump 3. The outlet pipes 8 allow the refrigerant, after heat exchange within the refrigerant tube racks 6, to drain smoothly, forming a complete circulation loop and continuously cooling the molten liquid within the mold blank 2, ensuring the continuity and stability of the cooling effect. The outer wall of the outlet pipe 8 is fixedly connected to the inner wall of the mold blank 2. This fixed connection method ensures the stability of the outlet pipe 8, preventing it from shaking or shifting during drainage, ensuring the normal and stable operation of the entire refrigerant circulation system, and continuously providing cooling for cylinder head production.
[0037] The inner wall of the die blank 2 has slots 21. These slots 21 provide suitable space and positioning for the installation of components such as the refrigeration tube rack 6, and may also assist in the flow and heat dissipation of the molten liquid within the die blank 2, thus improving the relevant performance during cylinder head production. The outer wall of the refrigeration tube rack 6 is fixedly connected to the inner wall of the die blank 2. This tight connection ensures good heat conduction between the refrigeration tube rack 6 and the die blank 2, allowing the refrigerant within the refrigeration tube rack 6 to efficiently absorb the heat from the molten liquid within the die blank 2, accelerating the cooling rate and improving the production efficiency of the cylinder head.
[0038] Reference Figures 1 to 3 The movable assembly includes a base plate 10, which serves as the bottom support structure for the entire movable assembly. The base plate 10 provides a stable mounting foundation for other components above, bears the entire movable assembly and the reaction force generated during the ejection operation, ensuring the overall stability of the movable assembly. Two support plates 9 are fixedly connected to the bottom of the operating platform 1. The support plates 9 provide vertical support to the entire movable assembly from both sides of the bottom of the operating platform 1, distributing the weight of the components above and the force generated during operation, thus enhancing the stability of the connection between the movable assembly and the operating platform 1.
[0039] A fixing plate 20 is fixedly connected to the bottom of the two support plates 9. The fixing plate 20 further stabilizes the structure of the entire moving assembly, providing a flat and secure mounting surface for key components such as the motor 11, ensuring that the components will not wobble or affect the ejection effect during operation. The motor 11 is fixedly connected to the top of the fixing plate 20. As the power source of the moving assembly, the motor 11 drives the disc 12 to rotate after starting, providing stable power for subsequent ejection operations, driving the relevant components to move along the set trajectory, and achieving precise ejection function;
[0040] A disk 12 is fixedly connected to the drive end of the motor 11. Driven by the motor 11, the disk 12 performs circular motion, effectively converting the rotational power of the motor 11 into a force that can move other components. Through its connection with the follower plate 13, force is transmitted, thereby facilitating the ejection operation. The follower plate 13 is rotatably connected to the end of the disk 12 furthest from the motor 11. The follower plate 13 moves with the rotation of the disk 12, serving to connect the disk 12 and the cylinder 14, converting the circular motion of the disk 12 into the linear motion of the cylinder 14, making the ejection action smoother and more orderly.
[0041] A base plate 10 is fixedly connected to the bottom of the two support plates 9. This connection method further enhances the stability of the bottom structure of the entire moving assembly, enabling the base plate 10 to better withstand the various forces generated during the entire moving assembly and the ejection operation, ensuring the stable and reliable operation of the moving assembly. The top of the base plate 10 is fixedly connected to the bottom of the fixed plate 20. This connection allows the fixed plate 20 to be more securely mounted on the base plate 10, preventing components such as the motor 11 mounted on the fixed plate 20 from shaking or shifting due to force during operation, thus ensuring the accuracy of the ejection operation.
[0042] A cylinder 14 is slidably connected to the end of the follower plate 13 away from the disk 12. Driven by the follower plate 13, the cylinder 14 slides along a specific trajectory, converting the power transmitted from the follower plate 13 into its own linear motion, thereby achieving the ejection action of the formed cylinder head. The sliding connection ensures the smoothness and accuracy of the movement. The outer wall of the cylinder 14 is slidably connected to the inner wall of the operating table 1. This sliding connection allows the cylinder 14 to move along a predetermined linear direction under the constraint of the inner wall of the operating table 1, accurately transmitting power to the cylinder head that needs to be ejected, facilitating its ejection from the mold blank 2 and making it easy to remove.
[0043] Reference Figure 1 , Figure 3 and Figure 4 The processing components include telescopic columns 15, which can play a supporting and guiding role in the cylinder head processing process, ensuring that the upper mold 17 can be raised and lowered stably in the vertical direction, ensuring that the upper mold 17 and the mold blank 2 move accurately when closing and opening the mold, and avoiding situations such as skewing that affect product quality.
[0044] The bottoms of four telescopic columns 15 are fixedly connected to the top of the operating platform 1, and the tops of the four telescopic columns 15 are fixedly connected to the upper mold 17. Through this connection method, the upper mold 17 is securely installed above the telescopic columns 15. Supported and guided by the telescopic columns 15, it can accurately cooperate with the mold blank 2 to complete the forming of the cylinder head. The top of the upper mold 17 is fixedly connected to a mounting plate 16. The mounting plate 16 provides a suitable mounting position for the hydraulic cylinder 19, allowing the hydraulic cylinder 19 to be securely installed above the upper mold 17 and facilitating the effective transmission of the force from the hydraulic cylinder 19 to the upper mold 17, thus realizing the lifting and lowering action of the upper mold 17.
[0045] A hydraulic cylinder 19 is fixedly connected to the top of the mounting plate 16. As a key component providing lifting power in the processing assembly, the hydraulic cylinder 19 works on the principle of hydraulics and can generate sufficient thrust or pull to drive the upper mold 17 to move up and down under the guidance of the telescopic column 15, so as to realize the mold closing and opening operation with the mold blank 2. The top of the hydraulic cylinder 19 is provided with a liquid injection hole 18, which facilitates the injection of hydraulic oil into the hydraulic cylinder 19. By controlling the amount and pressure of hydraulic oil, the telescopic movement of the hydraulic cylinder 19 can be adjusted, thereby precisely controlling the lifting and lowering of the upper mold 17 and ensuring the smooth progress of the processing.
[0046] The inner wall of the upper mold 17 is provided with a molten injection hole 18, which provides an inlet for injecting molten metal for forming the cylinder head into the mold blank 2. This allows the molten metal to flow accurately into the corresponding space within the mold blank 2 and gradually solidify and form the desired shape. The bottom of the upper mold 17 is coupled to the inner wall of the mold blank 2. This coupling connection ensures the sealing between the upper mold 17 and the mold blank 2, preventing leakage during molten metal injection. It also allows the two to form a complete forming space after mold closing, which is beneficial for the accurate forming of the cylinder head.
[0047] Working Principle: During cylinder head manufacturing, the upper mold 17, guided by the telescopic column 15, precisely engages with the mold blank 2, forming a closed and stable cavity space. At this time, molten metal for forming the cylinder head is injected through the injection hole 18 on the inner wall of the upper mold 17. Next, the small water pump 3 is activated, using its own power to deliver the refrigerant through the inlet hose 4 to the tee pipe 5. After being evenly distributed through the tee pipe 5, the refrigerant enters two refrigerant tube racks 6. The refrigerant tube racks 6 are located at key positions inside the mold blank 2. During the circulation process, the refrigerant inside these racks quickly absorbs heat from the molten metal inside the mold blank 2, causing the molten metal temperature to drop rapidly and accelerating its cooling and solidification process. This effectively shortens the cylinder head production cycle and improves production efficiency. After the refrigerant completes heat exchange, it flows out of the refrigerant tube racks 6 through the outlet pipe 8 and returns to the refrigerant storage device along a pre-set pipeline loop or continues to participate in the next round of refrigeration.
[0048] After material production is completed, hydraulic cylinder 19 is activated, controlling the retraction of telescopic column 15 through the inflow and outflow of hydraulic oil, thereby smoothly raising upper mold 17. Then, motor 11 is turned on, driving disc 12 to rotate. As disc 12 rotates, its end away from motor 11 is rotatably connected to follower plate 13, causing follower plate 13 to move accordingly under the influence of disc 12. The end of follower plate 13 away from disc 12 is slidably connected to cylinder 14, while the outer wall of cylinder 14 is slidably connected to the inner wall of operating table 1. This ingenious connection method transforms the circular motion of disc 12 into linear motion of cylinder 14 within operating table 1 and mold blank 2. During its movement, cylinder 14 precisely presses against the formed cylinder head, smoothly ejecting it from mold blank 2. This facilitates easy material handling by operators, reducing the difficulty and time cost of manual material removal and improving the convenience and automation of the entire production process.
