Energy-saving furnace roller automatic cooling mold casting equipment

Abstract

The present invention relates to the technical field of casting equipment, and discloses an energy-saving furnace roller automatic cooling mold opening casting equipment, comprising an upper mold, a lower mold, an upper locking assembly, a lower locking assembly, and a jacking assembly. After the casting is completed, the present invention continuously inputs coolant into the water inlet, and the outlet of the lower mold cooling cavity is blocked by the sealing column. The coolant gradually accumulates in the closed lower mold cooling cavity, so that the liquid pressure gradually rises in a stable and controllable trend. As the pressure continues to increase, the sealing plate is subjected to a bottom-up thrust, pushing the sealing column to move upward. In this process, the liquid pressure does not erupt instantly, but increases step by step, effectively avoiding damage to the mold caused by the impact force. When the sealing column moves to the limit plate, the rising pressure will push the upper mold to rise steadily, realizing automatic mold opening. This method of using the gradual rise in liquid pressure to complete mold opening does not require an additional power device, reduces the difficulty of maintenance, and saves a lot of energy consumption.

Description

Technical Field

[0001] The invention belongs to the technical field of casting equipment, and in particular relates to energy-saving furnace roller automatic cooling and mold opening casting equipment. Background Art

[0002] In the furnace roller casting production process, mold cooling and mold opening are key links to ensure casting quality and production efficiency.

[0003] In the prior art, a hydraulic system is often used as a separation power device when the upper mold and the lower mold are separated. The hydraulic system can generate extremely high thrust at the moment of startup. Although this powerful thrust can achieve mold separation, due to the huge thrust when the hydraulic system is started, a strong impact force will be generated during the mold opening process, resulting in increased mold wear, affecting the service life of the mold, increasing the cost of mold replacement, and may also have an adverse effect on the surface quality of the casting. In addition, the hydraulic system has a complex structure and needs to be equipped with a special hydraulic pump station, pipeline and control system, resulting in high equipment purchase costs, and difficult and high maintenance costs in the later stage. Moreover, after the mold is opened, the cooling chamber is in an open state, and a part of the coolant that has not yet returned will be directly spilled on the work site, which not only causes a large amount of coolant waste and increases the company's production material costs, but also makes the work floor slippery, posing safety hazards such as slipping to operators.

[0004] In view of this, the present invention is proposed. Summary of the Invention

A water inlet is provided at the bottom of the lower mold, and the water inlet is connected to the cooling cavity inside the lower mold.

[0015] As a preferred embodiment of the present invention, a through hole is opened inside the upper mold, and the sealing column is movably inserted into the through hole. An input port and an output port are respectively opened on the surface of the sealing column, and the input port and the output port are interconnected with the circulation channel.

[0016] As a preferred embodiment of the present invention, the end face of the through hole is provided with an inner groove with a diameter larger than the diameter of the through hole, the inner groove corresponds to the output port, and several pairs of blocking blocks are installed on the inner groove, and the blocking blocks are used to seal the output port when the jacking assembly drives the sealing column to rotate.

[0017] As a preferred embodiment of the present invention, a pressure plate is rotatably installed on the top of the sealing column, a connecting frame is installed on the pressure plate, a limiting rod is movably inserted and inserted inside the connecting frame, the bottom of the limiting rod is installed on the upper mold, and a limiting plate is installed on the top of the limiting rod, a limiting spring is sleeved on the limiting rod, one end of the limiting spring is clamped under the connecting frame, and the other end of the limiting spring is clamped on the upper mold, and the limiting spring is in a stretched state.

[0018] As a preferred embodiment of the present invention, a connecting cavity is provided on the lower mold, and a pouring port smaller in size than the connecting cavity is provided at the end of the connecting cavity. The size of the pouring port is matched with the size of the sealing column. The diameter of the sealing plate is larger than the diameter of the pouring port and smaller than the size of the connecting cavity, and a guide ring is rotatably installed on the sealing plate, and the guide ring is in contact with the bottom of the sealing column.

[0019] As a preferred embodiment of the present invention, a positioning plate is installed on the side wall of the connecting cavity, the sealing plate is placed above the positioning plate, a guide rod is installed at the bottom of the sealing plate, the guide rod movably passes through the positioning plate, a guide plate is installed at the bottom of the guide rod, a tension spring is sleeved on the guide rod, one end of the tension spring is clamped to the bottom of the guide plate, and the other end is clamped to the positioning plate.

[0020] As a preferred embodiment of the present invention, the lifting assembly includes a synchronization shaft, which is movably connected to the upper mold, and a knob is installed on the top of the synchronization shaft, a protrusion is installed on the top of the knob, and a special-shaped plug-in shaft is installed on the bottom of the synchronization shaft, and the special-shaped plug-in shaft is movably plugged into the sealing column, and the unlocking assembly includes a protrusion, and the protrusion is interconnected with the synchronization shaft.

[0021] As a preferred embodiment of the present invention, the unlocking assembly also includes a card plate, which movably passes through the side wall of the upper mold, and the end of the card plate is inserted into the card groove opened on the side wall of the lower mold, and the end face of the card plate is in contact with the protrusion. The side wall of the card plate is installed with a side plate, and a sliding rod is movably installed inside the side plate. The sliding rod is installed on the side wall of the upper mold, and a compression spring is sleeved on the sliding rod.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The upper and lower molds of the present invention are respectively equipped with upper and lower locking assemblies. The sealing design of the sealing column and sealing plate when not assembled effectively prevents coolant leakage, avoiding resource waste, achieving energy savings, and reducing safety hazards. When the upper and lower molds are assembled, the efficient coolant circulation channel formed by the interconnected cooling cavities quickly and evenly cools the mold cavity, precisely meeting the strict temperature control requirements of the casting process, significantly reducing casting defects caused by temperature incompatibility, and significantly lowering production costs.

[0024] After the casting is completed, the present invention drives the sealing column to rotate through the jacking assembly to accurately block the channel. At this time, since the water inlet continuously inputs coolant, and the outlet of the lower mold cooling cavity is blocked by the sealing column, the coolant gradually accumulates in the closed lower mold cooling cavity, causing the liquid pressure to gradually rise in a stable and controllable trend. As the pressure continues to increase, the sealing plate is pushed from the bottom up, thereby pushing the sealing column to move upward. In this process, the liquid pressure does not erupt instantly, but increases step by step, effectively avoiding damage to the mold caused by the impact force. When the sealing column moves to the limit plate, the continuously rising pressure will push the upper mold to rise smoothly, realizing automatic mold opening. This method of using the gradual rise in liquid pressure to complete mold opening does not require an additional power device, simplifies the equipment structure, reduces the difficulty of maintenance, and saves a lot of energy consumption.

[0025] After the mold is opened, the upper and lower locking assemblies of the present invention resume their function, with the sealing column and sealing plate sealing the cooling cavities of the upper and lower molds, respectively, to prevent coolant from spilling. This sealing mechanism, on the one hand, avoids coolant waste, lowering the company's production material costs and reducing the resource consumption associated with frequent coolant replenishment; on the other hand, it prevents coolant from spilling onto the worksite, avoiding safety accidents such as operators slipping due to slippery floors, effectively ensuring a safe production environment in the workshop and achieving high efficiency, safety, and environmental protection throughout the entire equipment operation process.

[0026] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0044] Example 1, as Figures 1 to 8 As shown, an energy-saving furnace roller automatic cooling mold casting device includes an upper mold 1 and a lower mold 2.

[0045] A cooling cavity 3 is provided inside the upper mold 1 and the lower mold 2 for cooling the mold cavity;

[0046] An upper locking assembly is installed inside the upper mold 1. The upper locking assembly includes a sealing column 4 for sealing the cooling cavity 3 when the upper mold 1 is not assembled. A flow channel 42 is provided inside the sealing column 4 for opening the corresponding cooling cavity 3.

[0047] A lower locking assembly is installed inside the lower mold 2, and the lower locking assembly includes a sealing plate 5 for sealing the cooling cavity 3 when the lower mold 2 is not assembled;

[0048] After the upper mold 1 and the lower mold 2 are assembled, the sealing column 4 in the upper locking assembly and the lower locking assembly are squeezed and matched with the sealing plate 5 to conduct the cooling cavity 3;

[0049] The upper mold 1 is also equipped with a lifting assembly, which is used to drive the sealing column 4 to rotate. After the sealing column 4 rotates, it blocks the flow channel 42, thereby increasing the pressure at the end of the sealing column 4 and lifting the upper mold 1 to separate from the lower mold 2.

[0050] The lifting assembly also drives the unlocking assembly in the upper mold 1 to unlock the upper mold 1 and the lower mold 2.

[0051] like Figures 1 to 8As shown, in a specific embodiment, a top seat 11 is mounted on the top of the upper mold 1, a base 21 is mounted on the bottom of the lower mold 2, a positioning rod 111 is mounted at the bottom corner of the upper mold 1, and an adaptive positioning hole 211 is formed in the lower mold 2, and the positioning rod 111 is movably inserted into the positioning hole 211. This positioning structure not only ensures that the upper mold 1 and the lower mold 2 are quickly and accurately aligned during assembly, but also effectively avoids mold misalignment caused by assembly errors, reduces casting scrap rate, improves product qualification rate, simplifies the assembly process, and shortens equipment preparation time.

[0052] like Figures 1 to 8 As shown, further, an injection hole 112 is provided on the top of the top seat 11, and the injection hole 112 is connected to the mold cavity enclosed by the upper mold 1 and the lower mold 2. A drain port 31 is installed on the top of the top seat 11, and the drain port 31 is connected to the cooling cavity 3 inside the upper mold 1. A water inlet 32 ​​is provided at the bottom of the lower mold 2, and the water inlet 32 ​​is connected to the cooling cavity 3 inside the lower mold 2. The rational layout of the inlet and outlet design allows the coolant to form an efficient circulation in the cooling cavity 3, which can quickly remove a large amount of heat generated by the mold during the casting process, effectively reduce the mold temperature, prevent the mold from deformation due to overheating, extend the mold service life, and reduce the cost of mold replacement. At the same time, stable temperature control can ensure that the casting has uniform structure during the cooling process and improve the mechanical properties of the casting.

[0053] Example 2, based on Example 1 and different from this example: Figures 1 to 8 As shown, a through hole 41 is provided inside the upper mold 1, and the sealing column 4 is movably inserted into the through hole 41. An input port 422 and an output port 421 are provided on the surface of the sealing column 4, respectively. The input port 422 and the output port 421 are both interconnected with the circulation channel 42. An inner groove 411 with a diameter larger than the diameter of the through hole 41 is provided on the end face of the through hole 41. The inner groove 411 corresponds to the output port 421. A plurality of pairs of blocking blocks 412 are installed on the inner groove 411. The blocking blocks 412 are used to seal the output port 421 after the jacking assembly drives the sealing column 4 to rotate. This ingenious sealing structure design can quickly block the coolant flow path when the mold is opened while ensuring the normal conduction of the cooling chamber 3, accurately control the pressure change in the cooling chamber 3, provide a reliable pressure drive source for automatic mold opening, and has a good sealing effect, preventing residual coolant from leaking, and ensuring a clean and safe working environment.

[0054] like Figures 1 to 8As shown, in a specific embodiment, a pressure plate 43 is rotatably mounted on the top of the sealing column 4, a connecting frame 431 is mounted on the pressure plate 43, a limit rod 432 is movably inserted and inserted into the connecting frame 431, the bottom of the limit rod 432 is mounted on the upper mold 1, and a limit plate 433 is mounted on the top of the limit rod 432, and a limit spring 434 is sleeved on the limit rod 432, one end of the limit spring 434 is clamped under the connecting frame 431, and the other end of the limit spring 434 is clamped on the upper mold 1, and the limit spring 434 is in a stretched state. The combination of the limit spring 434 and the limit rod 432 can provide a stable pre-tightening force for the sealing column 4, ensuring that the sealing column 4 can reliably seal the cooling chamber 3 in the non-working state. At the same time, during the assembly process, the sealing column 4 can adaptively adjust its position according to the mold matching situation, thereby enhancing the sealing effect between the sealing column 4 and the sealing plate 5, and improving the overall sealing and reliability of the equipment.

[0055] like Figures 1 to 8 As shown, the lower mold 2 further defines a connecting cavity 52, with a pouring port 521 smaller than the connecting cavity 52 at its end. The pouring port 521 matches the size of the sealing column 4. The diameter of the sealing plate 5 is larger than the diameter of the pouring port 521 but smaller than the size of the connecting cavity 52. ​​A guide ring 51 is rotatably mounted on the sealing plate 5, and the guide ring 51 abuts against the bottom of the sealing column 4. The provision of the guide ring 51 effectively reduces friction between the sealing column 4 and the sealing plate 5, allowing for smoother movement during the extrusion and fit process, reducing wear and extending the service life of the sealing component. It also ensures unimpeded flow of coolant during communication, guaranteeing cooling cycle efficiency.

[0056] like Figures 1 to 8 As shown, further, a positioning plate 522 is installed on the side wall of the connecting cavity 52, and the sealing plate 5 is placed above the positioning plate 522. A guide rod 53 is installed at the bottom of the sealing plate 5. The guide rod 53 movably passes through the positioning plate 522. A guide plate 531 is installed at the bottom of the guide rod 53. A tension spring 532 is sleeved on the guide rod 53. One end of the tension spring 532 is clamped to the bottom of the guide plate 531, and the other end is clamped to the positioning plate 522. The tension spring 532 cooperates with the guide rod 53 to play a buffering and resetting role during the opening and closing process of the sealing plate 5, preventing the sealing plate 5 from being damaged due to excessive impact force. At the same time, it ensures that the sealing plate 5 can quickly and accurately return to the sealing position, thereby improving the stability and reliability of the equipment operation and ensuring the consistency of the sealing of the cooling cavity 3 during each casting operation.

[0057] Example 3, based on Example 2 and different from this example: Figures 1 to 8As shown, the lifting assembly includes a synchronous shaft 6, which is movably connected to the upper mold 1. A knob 64 is installed on the top of the synchronous shaft 6, and a bump is installed on the top of the knob 64. A special-shaped plug shaft 63 is installed on the bottom of the synchronous shaft 6, and the special-shaped plug shaft 63 is movably plugged into the sealing column 4. The unlocking assembly includes a protrusion 61, and the protrusion 61 is interconnected with the synchronous shaft 6. Through the single operation of the knob 64, multiple actions such as rotating and unlocking the sealing column 4 can be achieved. The operation is simple and intuitive, reducing the labor intensity and difficulty of the operator, improving the automation level and production efficiency of the equipment, and at the same time reducing the complex connections between equipment components, reducing the equipment failure rate, and facilitating subsequent maintenance.

[0058] like Figures 1 to 8 As shown, in a specific embodiment, the unlocking assembly further includes a card plate 62, which movably extends through the side wall of the upper mold 1, and the end of the card plate 62 is inserted into a slot 621 provided in the side wall of the lower mold 2, and the end face of the card plate 62 is in contact with the protrusion 61. A side plate 622 is mounted on the side wall of the card plate 62, and a slide rod 623 is movably installed inside the side plate 622. The slide rod 623 is mounted on the side wall of the upper mold 1, and a compression spring 624 is sleeved on the slide rod 623. One end of the compression spring 624 is in contact with the side wall of the upper mold 1, and the other end is in contact with the side wall of the side plate 622. The locking structure composed of the card plate 62 and the compression spring 624 can provide a reliable locking force for the upper mold 1 and the lower mold 2 during the casting process, ensuring that the mold will not loosen or shift under high temperature and high pressure casting environments, ensuring stable casting quality. At the same time, when the mold is opened, the compression spring 624 can quickly push the card plate 62 back to its original position, achieving rapid unlocking and improving mold opening efficiency.

[0059] The implementation principle of the energy-saving furnace roller automatic cooling mold casting equipment of the present invention is as follows:

[0060] The upper die 1 and lower die 2 of this equipment are respectively provided with an upper locking assembly and a lower locking assembly:

[0061] When the upper mold 1 is not assembled, the upper locking assembly comes into play. At this time, under the elastic force of the limit spring 434, the sealing column 4 moves downward along the through hole 41, so that the output port 421 can be blocked by the through hole 41, and the cooling chamber 3 inside the upper mold 1 is sealed. In this way, when the upper mold 1 and the lower mold 2 are disassembled later, the liquid in the cooling chamber of the upper mold 1 will not spill out.

[0062] When the lower mold 2 is not assembled, the lower locking assembly comes into play. Under the elastic force of the tension spring 532, the sealing plate 5 will move, so that the sealing plate 5 and the end face of the connecting cavity 52 are fitted and sealed, thereby sealing the internal cooling cavity 3 to prevent coolant leakage.

[0063] This double-seal structure design further ensures the sealing of the equipment when it is not in operation, provides a good basic condition for subsequent work, and effectively guarantees the stability and safety of equipment operation.

[0064] During casting, the upper mold 1 and the lower mold 2 are assembled, and the positioning rod 111 is inserted into the positioning hole 211 to achieve precise positioning of the upper mold 1 and the lower mold 2. This positioning method is simple to operate and precise in positioning, which can effectively reduce assembly errors, improve production efficiency, and ensure the molding accuracy of castings.

[0065] During the assembly process, the sealing column 4 is squeezed and fitted with the sealing plate 5 , and then the sealing plate 5 and the sealing column 4 move.

[0066] First, the sealing plate 5 and the guide rod 53 slide downward along the positioning plate 522, thereby opening the connecting cavity 52, and the tension spring 532 is stretched synchronously at this time, which facilitates subsequent reset.

[0067] At this time, the sealing column 4 will be inserted into the connecting cavity 52, and the input port 422 can fall into the connecting cavity 52, and the sealing column 4 and the sealing plate 5 are squeezed against each other, so the sealing column 4 slides upward in the upper mold 1, and the output port 421 on the sealing column 4 slides out of the inner groove 411, and the cooling cavities 3 of the upper mold 1 and the lower mold 2 are connected to each other.

[0068] At this time, the coolant can enter the cooling cavity 3 of the lower mold 2 through the water inlet 32, and then enter the cooling cavity 3 of the upper mold 1 through the connecting cavity 52, the input port 422, the circulation channel 42 and the output port 421, and finally be discharged from the drain port 31, forming a cooling cycle to cool the mold cavity to meet the requirements of mold temperature control during the casting process and ensure the quality of the casting and the molding effect.

[0069] After the above structure is installed, the operator can rotate the protrusion 61, and the extrusion clamp 62 at the farthest end of the protrusion 61 can be inserted into the clamping groove 621, thereby completing the positioning of the lower mold 2 and the upper mold 1, ensuring stability during the casting process. This positioning and locking structure is simple and reliable, and can effectively prevent the mold from loosening during the casting process, ensuring the smooth progress of the casting process and improving the safety and reliability of production.

[0070] After casting is completed, the mold opening operation is required.

[0071] By rotating the knob 64, the synchronous shaft 6 rotates, and the protrusion 61 connected to the synchronous shaft 6 rotates synchronously. At this time, the farthest end of the protrusion 61 separates from the clamping plate 62. At this time, under the action of the compression spring 624, the end of the clamping plate 62 always fits against the outer edge of the protrusion 61, thereby disengaging the clamping plate 62 from the clamping groove 621 of the lower mold 2, and finally completing the unlocking operation of the upper mold 1 and the lower mold 2. This unlocking process is highly automated, simple and quick to operate, reducing the labor intensity of manual mold opening and improving production efficiency.

[0072] After the synchronous shaft 6 rotates, the special-shaped plug shaft 63 at the bottom of the synchronous shaft 6 drives the sealing column 4 to rotate. After the sealing column 4 rotates, the blocking block 412 seals the output port 421, and the circulation channel 42 is blocked. Since the water inlet 32 ​​has been inputting liquid, the pressure in the cooling chamber 3 in the lower mold 2 increases, and the sealing column 4 is lifted by the sealing plate 5 to move upward (at this time, the upper mold 1 and the lower mold 2 have been unlocked). When the sealing column 4 moves to the limit plate 433, as it continues to move, it can push the upper mold 1 to move upward, and finally the upper mold 1 can be smoothly lifted to remove the cast furnace roller casting. The whole process realizes the functions of mold cooling and automatic mold opening in the energy-saving furnace roller casting process, improves production efficiency, reduces labor intensity, and effectively avoids leakage of coolant through the sealing structure, achieving energy-saving and environmental protection effects. This automatic mold opening design uses liquid pressure to separate the molds without the need for an additional power device, which saves energy, simplifies the equipment structure, and reduces equipment cost and maintenance difficulty. The entire process realizes the functions of mold cooling and automatic mold opening during energy-saving furnace roller casting, significantly improves production efficiency, reduces labor intensity, and effectively avoids leakage of coolant through the sealing structure, achieving energy-saving and environmental protection effects.

[0073] After the upper mold 1 and the lower mold 2 are separated, the upper locking assembly and the lower locking assembly reseal the cooling cavity 3 to prepare for the next casting operation, ensuring the continuous and stable operation of the equipment and forming a complete production process that is efficient, energy-saving and environmentally friendly.
