Description

Technical Field

[0001] The present invention belongs to the technical field of casting equipment, and specifically relates to an energy-saving furnace roll automatic cooling and mold-opening casting equipment. Background Art

[0002] During the production process of furnace roll casting, the cooling and mold-opening of the mold are key links to ensure the quality of castings and production efficiency.

[0003] In the prior art, when the upper mold and the lower mold are separated, a hydraulic system is often used as the separation power device. At the moment of starting, the hydraulic system can generate extremely high thrust. Although this powerful thrust can achieve mold separation, due to the huge thrust when the hydraulic system starts, 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 mold replacement cost, and may also have an adverse impact on the surface quality of the castings. Moreover, the hydraulic system has a complex structure and requires a dedicated hydraulic pump station, pipelines and control systems, resulting in high equipment purchase costs, and difficult and costly later maintenance; and after the mold is opened, the cooling cavity is in an open state, and a part of the coolant that has not yet flowed back will directly spill on the working site, not only causing a large amount of waste of coolant, increasing the production material cost of the enterprise, but also making the working ground slippery, bringing safety hazards such as slipping to the operators.

[0011] As a preferred embodiment of the present invention, a pressing plate is rotatably installed at the top of the sealing column, a connecting frame is installed on the pressing plate, a limiting rod is movably inserted through the inside of the connecting frame, the bottom of the limiting rod is installed on the upper mold, and a limiting plate is installed at 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, the other end of the limiting spring is clamped on the upper mold, and the limiting spring is in a stretched state.

[0012] As a preferred embodiment of the present invention, a communication cavity is provided on the lower mold, an inlet port with a size smaller than that of the communication cavity is provided at the end of the communication cavity, the size of the inlet port is adapted to the size of the sealing column, the diameter of the sealing plate is larger than the diameter of the inlet port and smaller than the size of the communication cavity, and a guiding ring is rotatably installed on the sealing plate, and the guiding ring is attached to the bottom of the sealing column.

[0015] As a preferred embodiment of the present invention, the unlocking assembly further includes a clamping plate. The clamping plate movably penetrates through the side wall of the upper mold, and the end of the clamping plate is inserted into a card slot opened in the side wall of the lower mold, and the end face of the clamping plate is attached to the protrusion.

[0016] The present invention has the following beneficial effects compared with the prior art: The upper mold and the lower mold of the present invention are respectively provided with an upper locking and stopping assembly and a lower locking and stopping assembly. Through the sealing design of the sealing column and the sealing plate when not assembled, it effectively prevents the leakage of the coolant, not only avoids waste of resources, realizes the energy-saving effect, but also reduces potential safety hazards. When the upper and lower molds are assembled, the efficient coolant circulation channel formed by the connection of the cooling cavities can quickly and evenly cool the mold cavity, accurately meet the strict temperature control requirements during the casting process, greatly reduce the casting defects caused by unsuitable temperature, and significantly reduce the production cost. After the casting is completed in the present invention, the sealing column is driven to rotate by the jacking assembly to accurately block the channel. At this time, since the coolant is continuously input from the water inlet, and the outlet of the cooling cavity of the lower mold is blocked by the sealing column, the coolant gradually accumulates in the closed cooling cavity of the lower mold, making the liquid pressure gradually rise in a stable and controllable trend. As the pressure continues to increase, the sealing plate is pushed by the upward thrust, and then the sealing column is pushed upward. In this process, the liquid pressure does not burst instantaneously, but increases gradually, effectively avoiding damage to the mold caused by the impact force. When the sealing column moves to the limiting plate, the continuously rising pressure will push the upper mold to rise smoothly, realizing automatic mold opening. This method of using the gradually rising liquid pressure to complete mold opening does not require an additional power device, simplifies the equipment structure, reduces the maintenance difficulty, and saves a large amount of energy consumption at the same time. After the mold opening is completed, the upper and lower locking components come into play again. The sealing column and the sealing plate seal the cooling cavities of the upper mold and the lower mold respectively, ensuring that the coolant does not spill. This sealing mechanism, on the one hand, avoids the waste of coolant, reduces the production material cost of the enterprise, and reduces the resource consumption caused by frequent replenishment of coolant; on the other hand, it prevents the coolant from spilling onto the working site, avoiding safety accidents such as operators slipping due to wet ground, effectively ensuring the safe production environment of the workshop, and realizing the high efficiency, safety and environmental protection of the whole process of equipment operation.

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0020] Embodiment 1, as Figures 1 to 8 shown, an energy-saving furnace roll automatic cooling and die-casting device includes an upper die 1 and a lower die 2.

[0021] Cooling cavities 3 for cooling the die cavities are provided inside the upper die 1 and the lower die 2; An upper locking component is installed inside the upper die 1. The upper locking component includes a sealing column 4 for sealing its cooling cavity 3 when the upper die 1 is not assembled. A flow passage 42 for opening the corresponding cooling cavity 3 is provided inside the sealing column 4; A lower locking component is installed inside the lower die 2. The lower locking component includes a sealing plate 5 for sealing its cooling cavity 3 when the lower die 2 is not assembled; After the upper die 1 and the lower die 2 are assembled, the sealing column 4 and the sealing plate 5 in the upper locking component and the lower locking component are in extrusion fit to conduct the cooling cavity 3; The upper die 1 is further provided with a jacking component. The jacking component is used to drive the sealing column 4 to rotate, and after the sealing column 4 rotates, the flow passage 42 is blocked, so as to increase the pressure at the end of the sealing column 4 and thus jack the upper die 1 away from the lower die 2; The jacking component also drives the unlocking component in the upper die 1 to unlock the upper die 1 and the lower die 2.

[0022] As Figures 1 to 8 shown, in the specific implementation manner, a top seat 11 is installed at the top of the upper die 1, a base 21 is installed at the bottom of the lower die 2, positioning rods 111 are installed at the bottom corners of the upper die 1, and matching positioning holes 211 are provided on the lower die 2. The positioning rods 111 are movably inserted into the positioning holes 211. Through this positioning structure, not only can the upper die 1 and the lower die 2 be quickly and accurately aligned during assembly, but also the problem of die misalignment caused by assembly errors can be effectively avoided, reducing the scrap rate of castings, improving the product qualification rate, simplifying the assembly process at the same time, and shortening the equipment preparation time.

[0023] As Figures 1 to 8As shown, further, an injection hole 112 is provided on the top of the top seat 11, and the injection hole 112 is communicated with the mold cavity surrounded 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 communicated with 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 communicated with the cooling cavity 3 inside the lower mold 2. The rationally arranged inlet and outlet design enables the coolant to form an efficient circulation in the cooling cavity 3, which can quickly take away a large amount of heat generated by the mold during the casting process, effectively reduce the mold temperature, avoid deformation of the mold due to overheating, extend the service life of the mold, and reduce the cost of mold replacement. At the same time, stable temperature control can ensure uniform organization of the casting during the cooling process and improve the mechanical properties of the casting.

[0024] Embodiment 2, based on embodiment 1 and different from this embodiment, is as follows: 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 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 when the lifting 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 driving source for automatic mold opening, and has a good sealing effect to prevent residual leakage of coolant, ensuring a clean and safe working environment.

[0025] like Figures 1 to 8 As 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 inside 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 a non-working state, and at the same time, during the assembly process, the sealing column 4 can adaptively adjust its position according to the mold matching situation, enhance the sealing effect between the sealing column 4 and the sealing plate 5, and improve the overall sealing and reliability of the equipment.

[0026] like Figures 1 to 8As shown in the figure, further, a communication cavity 52 is formed in the lower mold 2. An inlet 521 with a size smaller than that of the communication cavity 52 is formed at the end of the communication cavity 52. The size of the inlet 521 is adapted to the size of the sealing column 4. The diameter of the sealing plate 5 is larger than that of the inlet 521 and smaller than the size of the communication cavity 52. A guiding ring 51 is rotatably installed on the sealing plate 5, and the guiding ring 51 is in contact with the bottom of the sealing column 4. The setting of the guiding ring 51 can effectively reduce the friction between the sealing column 4 and the sealing plate 5, making the actions of the two more smooth during the extrusion fit process, reducing wear, extending the service life of the sealing components, and ensuring unobstructed circulation of the coolant during connection, thus guaranteeing the cooling cycle efficiency.

[0027] As Figures 1 to 8 shown in the figure, further, a positioning plate 522 is installed on the side wall of the communication cavity 52. The sealing plate 5 is placed above the positioning plate 522. A guiding rod 53 is installed at the bottom of the sealing plate 5. The guiding rod 53 movably penetrates through the positioning plate 522. A guiding plate 531 is installed at the bottom of the guiding rod 53. A tension spring 532 is sleeved on the guiding rod 53. One end of the tension spring 532 is clamped at the bottom of the guiding plate 531, and the other end is clamped on the positioning plate 522. The cooperation of the tension spring 532 and the guiding rod 53 plays a buffering and resetting role during the opening and closing processes of the sealing plate 5, avoiding damage to the sealing plate 5 due to excessive impact force, ensuring that the sealing plate 5 can quickly and accurately return to the sealing position, improving the stability and reliability of the equipment operation, and guaranteeing the consistency of the sealing of the cooling cavity 3 during each casting operation.

[0028] Embodiment 3, which is different from Embodiment 2 in this embodiment: As Figures 1 to 8 shown in the figure, the jacking assembly includes a synchronous shaft 6. The synchronous shaft 6 is movably connected to the upper mold 1. A knob 64 is installed at the top of the synchronous shaft 6. A convex block is installed at the top of the knob 64. An irregular insertion shaft 63 is installed at the bottom of the synchronous shaft 6. The irregular insertion shaft 63 is movably inserted into the sealing column 4. The unlocking assembly includes a protrusion 61, and the protrusion 61 is connected to the synchronous shaft 6. Through the operation of a single knob 64, multiple actions such as the rotation and unlocking of the sealing column 4 can be achieved. The operation is simple and intuitive, reducing the labor intensity and operation difficulty of the operator, improving the automation degree and production efficiency of the equipment, reducing the complex connections between the equipment components, lowering the equipment failure rate, and facilitating later maintenance.

[0029] As Figures 1 to 8As shown, in the specific implementation, the unlocking component further includes a clamping plate 62. The clamping plate 62 movably penetrates through the side wall of the upper mold 1, and the end of the clamping plate 62 is inserted into a clamping groove 621 formed in the side wall of the lower mold 2. The end face of the clamping plate 62 is in contact with the protrusion 61. A side plate 622 is installed on the side wall of the clamping plate 62. A sliding rod 623 is movably penetrated through the inside of the side plate 622. The sliding rod 623 is installed on the side wall of the upper mold 1. A compression spring 624 is sleeved on the sliding 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 clamping 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 the high-temperature and high-pressure casting environment, guaranteeing the stable forming quality of the casting. At the same time, when opening the mold, the compression spring 624 can quickly push the clamping plate 62 to reset, realizing rapid unlocking and improving the mold opening efficiency.

[0030] The implementation principle of an energy-saving furnace roller automatic cooling mold opening casting device of the present invention is as follows: An upper locking component and a lower locking component are respectively arranged in the upper mold 1 and the lower mold 2 of this device: Among them, when the upper mold 1 is not assembled, the upper locking component plays a role. At this time, under the elastic force of the limiting spring 434, the sealing column 4 moves downward along the through hole 41 at this time, so that the output port 421 can be blocked by the through hole 41 at this time, and thus the cooling cavity 3 inside the upper mold 1 is sealed, so that when the upper mold 1 and the lower mold 2 are disassembled later, the liquid in the cooling cavity of the upper mold 1 will not spill out.

[0031] When the lower mold 2 is not assembled, the lower locking component plays a role. 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 communication cavity 52 are in contact and sealed, thereby sealing the internal cooling cavity 3 to prevent the coolant from leaking.

[0032] This double-sealing structure design further ensures the sealing performance of the device in the non-working state, provides good basic conditions for subsequent work, and effectively guarantees the stability and safety of the device operation.

[0033] When casting operations are carried out, 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 accurate in positioning, can effectively reduce assembly errors, improve production efficiency, and ensure the forming accuracy of the casting.

[0034] During the assembly process, the sealing column 4 and the sealing plate 5 are in extrusion fit, and thus the sealing plate 5 and the sealing column 4 move.

[0035] First, the sealing plate 5 and the guide rod 53 slide downward along the positioning plate 522 at this time, which can open the communication cavity 52. At this time, the tension spring 532 is stretched synchronously, which is convenient for later resetting through the tension spring 532.

[0036] And the sealing column 4 will be inserted into the communication cavity 52 at this time, and the input port 422 can fall into the communication cavity 52 at this time. The sealing column 4 and the sealing plate 5 are pressed against each other. Therefore, the sealing column 4 slides upward in the upper die 1 at this time, and the output port 421 on the sealing column 4 slides out of the inner groove 411. At this time, the cooling cavities 3 of the upper die 1 and the lower die 2 are interconnected.

[0037] At this time, the coolant can enter the cooling cavity 3 of the lower die 2 through the water inlet 32, then pass through the communication cavity 52, the input port 422, the flow channel 42 and the output port 421 to enter the cooling cavity 3 of the upper die 1, and finally be discharged from the drain port 31 to form a cooling cycle to cool the mold cavity to meet the requirements of mold temperature control during the casting process and ensure the quality and forming effect of the casting.

[0038] After the above structure is installed, the operator can rotate the protrusion 61. At this time, the outermost end of the protrusion 61 presses the clamping plate 62 and can be inserted into the card slot 621, thereby completing the positioning of the lower die 2 and the upper die 1 and ensuring the stability during the casting process. This positioning and locking structure is simple and reliable, can effectively prevent the loosening of the mold during the casting process, ensures the smooth progress of the casting process, and improves the safety and reliability of production.

[0039] After casting is completed, a mold opening operation is required.

[0040] By rotating the knob 64, the synchronous shaft 6 is driven to rotate, and the protrusion 61 connected to the synchronous shaft 6 rotates synchronously. At this time, the outermost 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 causing the clamping plate 62 to disengage from the card slot 621 of the lower die 2, and finally completing the unlocking operation of the upper die 1 and the lower die 2. This unlocking process has a high degree of automation, is simple and fast to operate, reduces the labor intensity of manual mold opening, and improves production efficiency.

[0041] After the synchronous shaft 6 rotates, the special-shaped insertion shaft 63 at the bottom of the synchronous shaft 6 drives the sealing column 4 to rotate. After the sealing column 4 rotates, the shielding block 412 seals the output port 421, and the flow channel 42 is blocked. Since the water inlet 32 has been inputting liquid all the time, the pressure in the cooling cavity 3 of the lower mold 2 increases, and then the sealing column 4 is jacked up 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, and then with continuous movement, it can push the upper mold 1 to move upward, and finally the upper mold 1 can be smoothly lifted to facilitate the removal of the cast furnace roll casting. The whole process realizes the functions of mold cooling and automatic mold opening in the energy-saving furnace roll casting process, improves the production efficiency, reduces the labor intensity, and effectively avoids the leakage of the coolant through the sealing structure, achieving the effects of energy saving and environmental protection. This design of automatic mold opening uses liquid pressure to separate the mold, without an additional power device, which not only saves energy but also simplifies the equipment structure, reduces the equipment cost and maintenance difficulty. The whole process realizes the functions of mold cooling and automatic mold opening in the energy-saving furnace roll casting process, significantly improves the production efficiency, reduces the labor intensity, and effectively avoids the leakage of the coolant through the sealing structure, achieving the effects of energy saving and environmental protection.

[0042] After the upper mold 1 and the lower mold 2 are separated, the upper locking assembly and the lower locking assembly reseal their cooling cavity 3 to prepare for the next casting operation, ensuring the continuous and stable operation of the equipment and forming an efficient, energy-saving and environmentally friendly complete production process.
