Description

Technical Field

[0001] This invention belongs to the field of casting and processing technology for slender components, and particularly relates to a small-opening, short-stroke open mold closing mechanism for slender components. Background Technology

[0002] Currently, in the casting and processing field, the traditional solution of using a telescopic rod to drive the mold translation is commonly used for the mold opening and closing mechanism of slender components (length-to-diameter ratio not less than 5:1). This solution uses the linear motion of a hydraulic or electric telescopic rod to drive the mold to complete the opening and closing action.

[0003] However, this design pattern has obvious space utilization defects: since the mold translation trajectory is a linear reciprocating motion, the casting processing system must reserve sufficient lateral displacement space for the mold opening and closing process. This not only leads to a significant increase in the equipment footprint, but also limits the compact layout of the casting processing unit. Especially in multi-station collaborative casting processing or automated production line integration scenarios, the excessive mold opening and closing space requirement has become a key bottleneck restricting the improvement of production efficiency. Summary of the Invention

[0004] This invention provides a small-aperture, short-stroke open mold closing mechanism for slender components, aiming to solve the problem mentioned in the background art that when casting and processing slender components, the existing technology often directly uses a telescopic rod to push the mold to move and achieve mold opening and closing, which requires a sufficient space for mold opening and closing, which is inconvenient.

Detailed Implementation

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a small-aperture, short-stroke, open-type mold-closing mechanism for slender components, such as... Figure 1-11 As shown, the open-type mold closing mechanism for slender components with a small opening and short stroke includes: a support base 1, which is installed in the casting area of ​​the slender component on the mold closing structure body 42, and the support base 1 is installed in place of the mold closing structure body 42 in a corresponding position in the casting area of ​​the slender component; a fixing frame 2 fixed to the top of the support base 1; two half molds 3 hinged in the fixing frame 2 and arranged in a group, the two half molds 3 closing to form a molding space for accommodating the raw material of the component; a limiting structure provided on the support base 1 to help stabilize the closed state of the two half molds 3; an adjusting mechanism installed on the fixing frame 2 to adjust the closed state of the two half molds 3; and a material guiding structure provided on the support base 1 to assist in material discharge.

[0020] In this embodiment, the support base 1 is installed in the casting area of ​​the slender component with the mold closing structure body 42, replacing the mold closing structure body 42 in the corresponding position, so that this device replaces the original mold closing structure. When the two half molds 3 are closed, the limiting structure is sleeved on the outside of the half molds 3 to help stabilize their closed state and ensure the stability of the molding space. By setting the half mold 3 with a hinge, the traditional mold translation opening and closing mode is changed. There is no need to reserve a large amount of lateral displacement space for mold opening and closing, which improves space utilization, effectively reduces the equipment footprint, and enables the casting processing unit to achieve a compact layout. The setting of the limiting structure ensures the stability of the closed state of the half mold 3, which helps to improve the casting processing quality of the components. The setting of the adjustment mechanism can flexibly adjust the closed state of the half mold 3, which enhances the adaptability of the mold closing mechanism to the casting processing of components of different specifications. The setting of the material guiding structure assists in material discharge and keeps the casting processing area clean.

[0021] In a further preferred embodiment of the present invention, the limiting structure includes a fixed plate 4 fixed on the support base 1, a threaded rod 5 rotatably mounted on the fixed plate 4, an adjusting frame 6 threadedly sleeved on the threaded rod 5, and a limiting ring 7 fixed on the adjusting frame 6 and sleeved on the two half molds 3. A support wheel 8 is rotatably mounted on the adjusting frame 6, which contacts the top of the support base 1 to assist in supporting the limiting ring 7.

[0022] In this embodiment, when the two half molds 3 need to close to form a molding space, the limiting structure begins to function. When the threaded rod 5 is rotated, the adjusting frame 6 is threaded outside the threaded rod 5. The rotation of the threaded rod 5 will drive the adjusting frame 6 to move along the axial direction of the threaded rod 5. As the adjusting frame 6 moves, the limiting ring 7 fixed on the adjusting frame 6 also moves. When the two half molds 3 are closed to the appropriate position, the limiting ring 7 is fitted outside the two half molds 3, thereby limiting and stabilizing the closed state of the two half molds 3. By setting the threaded rod 5 and the adjusting bracket 6, the movement distance of the adjusting bracket 6 can be controlled by simply rotating the threaded rod 5, thereby adjusting the position of the limiting ring 7 and flexibly adjusting the restriction on the closed state of the two half molds 3. By making the limiting ring 7 fit outside the two half molds 3, it effectively prevents the half molds 3 from shifting or loosening due to force or other factors during the casting process, thus ensuring the stability of the molding space.

[0023] In a further preferred embodiment of the present invention, the semi-mold 3 includes a housing 11 with a rotating shaft 10 hinged to the fixed frame 2 for heat insulation, an inner mold 12 fixed in the housing 11, side baffles 13 disposed on both sides of the inner mold 12, and a filling port 14 installed on any one of the side baffles 13 for providing a feeding channel.

[0024] In this embodiment, when the two half molds 3 are closed, the inner mold 12 cooperates with each other to form a molding space for accommodating the component raw material. At the same time, the side baffles 13 fit together to further seal the molding space and prevent the component raw material from overflowing from the side during the casting process. The component raw material can be injected into the molding space through the filling port 14 for subsequent casting operations. By setting the outer shell 11, heat transfer can be effectively reduced, protecting the fixing frame 2 and other components from high temperature, extending the overall service life of the equipment, and also avoiding the instability of the inner mold 12 due to temperature changes, thus ensuring the casting processing accuracy. By setting the side baffle 13, the sealing of the molding space is optimized, which can effectively prevent the leakage of component raw materials during the casting process, reduce material waste and cleaning work, and improve production efficiency. By setting the filling port 14, a convenient channel is provided for the injection of component raw materials, making the feeding operation more convenient.

[0025] In a further preferred embodiment of the present invention, the adjustment mechanism includes a first motor 20 fixed on the fixed frame 2, a transmission shaft 34 rotatably mounted on the fixed frame 2 and connected to any one of the rotating shafts 10, a connecting member 24 disposed between the output shaft of the first motor 20 and the transmission shaft 34 for connecting and transmitting power, and gears 21 fixed on the transmission shaft 34 and the other rotating shaft 10 respectively and meshing with each other for transmission.

[0026] In this embodiment, when it is necessary to adjust the closed state of the two half molds 3, the first motor 20 is started, and its output shaft generates rotational power to drive the rotating shaft 10 to rotate. Through the transmission action of the gear 21, the other rotating shaft 10 is driven to rotate, so that the angle of the two half molds 3 changes, realizing synchronous opening and closing action, thereby adjusting the closed state of the two half molds 3 to meet different casting processing requirements. By setting the first motor 20 as the power source, a stable and continuous power can be provided, ensuring the reliability and stability of the adjustment action. The connection and transmission between the output shaft of the first motor 20 and the transmission shaft 34 are realized by setting the connector 24. The synchronous rotation of the two rotating shafts 10 is realized through the meshing transmission of the two gears 21, thereby ensuring that the two half molds 3 can open and close synchronously, improving the accuracy and consistency of the adjustment of the closed state of the two half molds 3, which is conducive to improving the casting and processing quality of slender components.

[0027] In a further preferred embodiment of the present invention, sprockets 22 are fixed on both the threaded rod 5 and the output shaft of the first motor 20. The same chain 23 for transmission is sleeved on both sprockets 22. The chain 23 meshes with the sprockets 22. The first motor 20 is covered with a protective shell for protecting the motor. The protective shell is provided with heat dissipation holes.

[0028] In this embodiment, after the first motor 20 is started, its output shaft begins to rotate. Since a sprocket 22 is fixed on the output shaft of the first motor 20, the rotation of the output shaft drives the sprocket 22 to rotate synchronously. The power is transmitted to the sprocket 22 on the threaded rod 5 through the chain 23, thereby driving the threaded rod 5 to rotate and realizing the adjustment function of the limit structure. By setting up sprocket 22 and chain 23, the first motor 20 can simultaneously drive the threaded rod 5 to rotate, achieving efficient power transmission and sharing. This reduces the need for additional power sources, lowers equipment costs and energy consumption, and makes the equipment structure more compact, saving installation space. The protective shell covering the first motor 20 provides effective protection for the motor, preventing external dust, debris, etc., from entering the motor and avoiding interference and damage to its normal operation, thus extending the motor's service life.

[0029] In a further preferred embodiment of the present invention, the material guiding structure includes a discharge port 28 disposed on the support base 1 and located at the bottom of the half mold 3, a material guiding frame 29 fixed to the bottom of the support base 1, and a plurality of support rollers 30 rotatably mounted on the material guiding frame 29 for supporting the slender component after molding.

[0030] In this embodiment, after the component is formed in the half mold 3, it needs to be transferred out of the casting processing position. At this time, the formed slender component will fall from the discharge port 28 located at the bottom of the half mold 3. The falling slender component will land directly on the support roller 30. The support roller 30 will rotate as the component moves, so that the formed slender component can slide smoothly and stably out of the casting processing area along the guide frame 29. By setting the discharge port 28, a direct and reasonable channel is provided for the discharge of the slender components after molding, so that the components can enter the material guiding process. By rotating and installing multiple support rollers 30 on the material guide frame 29, the friction between the slender components and the material guide frame 29 is reduced, the wear on the surface of the components is reduced, and the quality and appearance integrity of the components are guaranteed.

[0031] In a further preferred embodiment of the present invention, the connecting member 24 includes a mounting plate 31 fixed on the output shaft of the first motor 20, a connecting shaft 32 fixed on the mounting plate 31, a limiting cylinder 33 slidably sleeved outside the connecting shaft 32, a limiting block 35 fixed on the transmission shaft 34, the limiting block 35 extending into the limiting cylinder 33, a U-shaped plate 37 fixed on the mounting plate 31, and a spring 39 fixed on the U-shaped plate 37 for maintaining the connection state between the limiting cylinder 33 and the limiting block 35, and a support plate 38 connected to the limiting cylinder 33 fixed on the spring 39.

[0032] In this embodiment, when the first motor 20 starts, its output shaft begins to rotate, driving the mounting plate 31 fixed on the output shaft to rotate synchronously. Since the limiting cylinder 33 is slidably sleeved outside the connecting shaft 32, when the connecting shaft 32 rotates, the limiting cylinder 33 will follow the rotation trend. At this time, the limiting block 35 fixed on the transmission shaft 34 extends into the limiting cylinder 33. The limiting block 35 and the limiting cylinder 33 cooperate with each other to transmit the rotational power of the output shaft of the first motor 20 to the transmission shaft 34, thereby driving the transmission shaft 34 to rotate and realizing power transmission. By setting the limit block 35 and the limit cylinder 33 to cooperate, a stable and effective power transmission between the first motor 20 and the transmission shaft 34 is achieved. By setting the U-shaped plate 37 and the spring 39, the spring 39 can absorb and release energy, play a role in buffering and resetting, and keep the limit cylinder 33 sleeved outside the limit block 35 to maintain the transmission effect.

[0033] In a further preferred embodiment of the present invention, a guide 40 is fixed on the support plate 38, which movably passes through the spring 39 and extends into the U-shaped plate 37. The guide 40 is made of iron and is used to limit the extension and retraction path of the spring 39. An electromagnet 41 for attracting the guide 40 is fixed on the mounting plate 31.

[0034] In this embodiment, when the electromagnet 41 is not energized, it does not attract the iron guide frame 40, and the limiting cylinder 33 remains sleeved outside the limiting block 35. When the electromagnet 41 is energized, it attracts the iron guide frame 40, causing the guide frame 40 to move the support plate 38 and the limiting cylinder 33, thereby causing the limiting cylinder 33 to detach from the limiting block 35 and cutting off the power transmission between the output shaft of the first motor 20 and the transmission shaft 34. By setting up an electromagnet 41 and an iron guide frame 40, the half mold 3 can be prevented from opening and closing when the position of the limiting ring 7 is adjusted, thus affecting the limiting effect.

[0035] In a further preferred embodiment of the present invention, a push rod 15 is installed on the top inner wall of the fixing frame 2, which movably penetrates the outer shell 11 and the inner mold 12. The push rod 15 is used to assist in material discharge when the half mold 3 is open. The limiting block 35 is a polygonal prism. The limiting cylinder 33 is provided with a limiting chamber for accommodating the limiting block 35. The limiting block 35 slides in contact with the inner wall of the limiting chamber.

[0036] In this embodiment, after the component molding operation is completed, the first motor 20 drives the half mold 3 to open. When the half mold 3 is open, the push rod 15 is fixed in relative position, while the outer shell 11 and the inner mold 12 move as the half mold 3 opens. The push rod 15 will apply a pushing force to the slender component that remains in the inner mold 12 after molding, assisting in discharging the component from the inner mold 12 and realizing the material discharge operation. By setting the push rod 15, the slender components in the inner mold 12 can be automatically pushed to assist in material discharge. This effectively avoids the situation where the components are difficult to discharge due to the large friction between them and the inner mold 12, thus improving material discharge efficiency, reducing manual intervention, and lowering labor intensity. At the same time, it also ensures the continuity and smoothness of the production process. By using the limiting block 35 with a polygonal prism structure and making it slide in contact with the inner wall of the limiting chamber, stable power transmission can be provided.

[0037] In a further preferred embodiment of the present invention, a slider 9 connected to the adjusting frame 6 is slidably mounted on the support base 1, a guide groove 36 is provided on the connecting shaft 32, a guide block is slidably mounted in the guide groove 36, and the guide block is connected to the limiting cylinder 33.

[0038] In this embodiment, when the adjusting frame 6 and the limiting cylinder 33 move, the slider 9 and the guide block slide to limit the movement path of the component; The cooperation between the guide groove 36 and the guide block ensures that the guide block can only slide stably within the guide groove 36 under normal working conditions, thereby ensuring that the limit cylinder 33 and the connecting shaft 32 rotate synchronously and achieve reliable power transmission.

[0039] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a water tank 16 for storing cooling medium is installed on the top of the fixing frame 2. A water pump 17 is provided in the water tank 16. A drain pipe 18 connected to the outer shell 11 is installed at the drain end of the water pump 17. A return pipe 19 extending into the water tank 16 for guiding the cooling medium backflow is installed on the outer shell 11. Both the drain pipe 18 and the return pipe 19 are provided with retractable flexible hose sections.

[0040] In this embodiment, when it is necessary to cool down the outer casing 11 and related components of the equipment, the water pump 17 installed in the water tank 16 is started. The water pump 17 starts working and draws out the cooling medium in the water tank 16 through its drain end. The cooling medium flows along the drain pipe 18. Since the drain pipe 18 is connected to the outer casing 11, the cooling medium will enter the interior of the outer casing 11 and exchange heat with the outer casing 11 and related components inside it, absorbing the heat generated by the components during operation, thereby achieving the purpose of cooling. After the heat exchange is completed, the temperature of the cooling medium rises and flows back to the water tank 16 through the return pipe 19 installed on the outer casing 11 and extending into the water tank 16. By setting up a complete cooling circulation system consisting of a water tank 16, a water pump 17, a drain pipe 18, and a return pipe 19, the temperature of the equipment shell 11 and related components can be effectively reduced, increasing component forming efficiency and thus improving casting processing efficiency. During equipment operation, the components can move relative to each other. By setting up a telescopic hose section, it can freely extend and retract according to actual conditions, avoiding problems such as pipe rupture and loose connection caused by fixed pipe length, and ensuring the sealing and stability of the cooling medium circulation system.

[0041] In another embodiment of the present invention, a temperature sensor for monitoring the temperature of the cooling medium is provided inside the water tank 16, a cooling plate 26 for assisting in reducing the temperature of the cooling medium is fixed inside the water tank 16, a stirring rod is rotatably installed inside the water tank 16, and a second motor for driving the stirring rod to rotate is installed on the outer wall of the water tank 16, and the output shaft of the second motor is connected to the flange of the stirring rod.

[0042] In this embodiment, the temperature sensor inside the water tank 16 monitors the temperature of the cooling medium in real time. When the cooling medium absorbs heat from the equipment and its temperature rises, the temperature sensor transmits the detected temperature signal to the equipment's control system. If the temperature exceeds a preset safety threshold, the control system will activate the cooling plate 26. The cooling plate 26 starts working and absorbs heat from the cooling medium through its cooling function, thus lowering the temperature of the cooling medium. At the same time, the control system will also activate the second motor. The output shaft of the second motor drives the stirring rod to rotate through a flange connection. The stirring rod continuously stirs the cooling medium in the water tank 16, allowing the cooling medium to flow fully in the water tank 16. This allows the cooling plate 26 to cool the cooling medium more evenly, avoiding localized excessively high or low temperatures and ensuring the uniformity of the cooling medium temperature throughout the water tank 16. By setting a temperature sensor, the temperature of the cooling medium in the water tank 16 can be monitored in real time. This allows the equipment control system to make timely adjustments based on the actual temperature of the cooling medium. When the temperature is too high, cooling measures are taken in time, and unnecessary cooling operations are stopped when the temperature is within a suitable range. This achieves intelligent control of the cooling system, improves the operating efficiency and reliability of the cooling system, and effectively avoids adverse effects on the cooling effect and components caused by excessively high or low cooling medium temperatures. The cooling plate 26 can directly absorb heat from the cooling medium and lower its temperature. The stirring action of the stirring rod ensures that the cooling medium is evenly mixed in the water tank 16, allowing the cooling effect of the cooling plate 26 to be evenly applied to the entire cooling medium in the water tank 16, avoiding insufficient local cooling.

[0043] In another embodiment of the present invention, the water tank 16 is provided with an observation window 25 for displaying the remaining amount of cooling medium, the top of the water tank 16 is provided with a liquid replenishment port for providing a channel for adding cooling medium, the liquid replenishment port is also used to provide a pressure balance channel, and a dustproof net 27 for isolating dust and impurities is provided inside the liquid replenishment port.

[0044] In this embodiment, the operator can directly check the remaining amount of cooling medium in the water tank 16 through the observation window 25. When it is found that the remaining amount of cooling medium is insufficient, the operator can add cooling medium to the water tank 16 through the liquid replenishment port set on the top of the water tank 16. The observation window 25 provides operators with an intuitive and convenient viewing channel, allowing them to easily connect the remaining cooling medium in the water tank 16. This enables timely replenishment when the remaining medium is insufficient, ensuring the continuous and stable operation of the cooling system and preventing damage from overheating due to insufficient cooling medium. This improves the reliability and service life of the equipment. The replenishment port also functions as a cooling medium replenishment port and a pressure balancer, simplifying the structure of the water tank 16 and reducing additional openings and components. The pressure balancer function ensures stable pressure within the water tank 16, facilitating smooth flow of the cooling medium in the circulation system and improving cooling efficiency.

[0045] In summary, compared with related technologies, this device changes the traditional mold translation and opening mode by adopting a hinged half-mold 3, which eliminates the need for a large amount of lateral displacement space, improves space utilization, reduces the equipment footprint, and achieves a compact layout. By setting a limiting structure to stabilize the closed state of the half-mold 3, the stability of the molding space is ensured. By setting an adjustment mechanism to flexibly adjust the closed state of the half-mold 3, the adaptability can be enhanced. By setting a material guiding structure to assist in material discharge, the casting processing area can be kept clean.
