Description

Technical Field

[0001] This invention relates to the field of die casting technology, and more particularly to a die casting equipment and a die casting method. Background Technology

[0002] In die-casting equipment according to relevant technologies, the following technology is used: a pump located at the molten metal holding furnace and the molten metal supply port of the plunger sleeve are connected to each other through a connecting pipe; and molten metal drawn upward from the molten metal holding furnace by the pump is injected into the plunger sleeve through the connecting pipe. This configuration narrows the working space for replacing, for example, the plunger tip or the support shaft, thereby hindering maintenance efficiency.

[0003] Existing technologies, such as Chinese Patent Publication No. CN105312531A, disclose a die-casting equipment. Through the movable structure of the pump body and multiple pipe sections, the pump body can be set to be upright during maintenance, thus perpendicular to the horizontal plane in the molten metal holding furnace, preventing the pump from becoming an obstacle to the operator's maintenance work, thereby ensuring a sufficiently wide working space around the die-casting equipment. However, this technical solution has a drawback: the disassembly and separation of the pipes must be manually operated by the staff. During operation, being close to high-temperature equipment such as the molten metal holding furnace poses certain safety hazards. Moreover, the pipes use conventional flange bolt connections, making the disassembly and installation steps complex and not conducive to rapid maintenance.

[0004] Therefore, in response to the above-mentioned existing technologies, a new type of pipeline connection method can be designed, and a sensor can be used to send a signal to the control device for separating the pump body and the pipeline based on the action of pipeline disassembly, so as to achieve the purpose of disassembly and reassembly, reduce the danger of manual operation, and facilitate the rapid provision of maintenance space. Summary of the Invention

[0007] Preferably, the pressure application assembly includes a sleeve connected to the mold at one end and a plunger movably connected inside the sleeve. The plunger can move within the sleeve, and the sleeve is connected to the mold cavity. When the plunger moves within the sleeve, the raw material flows between the sleeve and the mold cavity.

[0008] Preferably, the manual drive assembly includes a turntable rotatably connected to a bracket, a front worm gear fixedly connected to the turntable, a crank handle with one end connected to an eccentric position on the turntable, a front worm movably connected to the bracket, an internal flat gear fixedly connected to one end of the worm, a gear ring rotatably connected to the bracket, and several external flat gears. The front worm gear meshes with the front worm. The gear ring has teeth on both its inner and outer walls. The internal flat gear meshes with the teeth on the inner wall of the gear ring, and the external flat gears mesh with the teeth on the outer wall of the gear ring. When the crank handle is turned, the front worm gear drives the front worm and the internal flat gear to rotate. The internal flat gear drives the gear ring to rotate, and the gear ring drives several external flat gears to rotate. The locking element includes a locking mechanism that engages with the external flat gears. The system comprises a fixed straight section and a sloping straight section connected to one side of the straight section. An inclined ramp structure connects the straight section and the sloping straight section. When the straight section rotates closer to the flange, the ramp structure slides on the flange surface until the sloping straight section abuts against the flange. Signal unit one includes a torsion spring and a torque sensor mounted on an external flat gear. One end of the torsion spring is fixedly connected to a bracket, and the other end is connected to the torque sensor, which detects the torque value of the torsion spring. When the external flat gear rotates until the sloping straight section abuts against the flange, the torque sensor detects a torque value of F1 for the torsion spring. When the external flat gear rotates until the straight section leaves the flange, the torque sensor detects a torque value of F2 for the torsion spring.

[0009] Preferably, the automatic drive assembly includes a drive motor mounted on the end plate, a bevel gear disk fixedly connected to the output end of the drive motor, a bevel gear movably connected within the end plate, a bevel gear seat movably connected within the inclined platform, and a lead screw. The bevel gear seat is fixedly connected to one end of the lead screw. The bevel gear has two bevel tooth surfaces, one of which meshes with the bevel gear disk, and the other meshes with the bevel gear seat. The drive motor drives the bevel gear disk to rotate. When the bevel gear disk rotates, it drives the lead screw to rotate through the bevel gear and the bevel gear seat. The sliding assembly includes a slide block slidably connected to the inclined platform, a slider fixedly connected to the slide block, and a support ring. The support ring has a semi-circular ring structure, and its center overlaps with the rotation center of the steering assembly. The slider is threadedly connected to the lead screw. When the lead screw rotates, it drives the slide block to move on the inclined platform. The steering assembly includes a support plate rotatably connected to the slide block at one end via a rotating shaft, a steering worm fixedly connected to the rotating shaft, and a support frame fixedly connected to the support plate. The support frame is slidably connected within the support ring, and the other end of the support frame is detachably connected to a connecting pipe.

[0010] Preferably, the linkage component one includes a transmission component one and a gas supply component two installed in the end plate. The input end of the transmission component one is connected to the output end of the automatic drive component, and the energy-absorbing component is installed between the output end of the transmission component one and the movable end of the gas supply component two. The linkage component two includes a transmission component two and a transmission component three installed on the slide. The output end of the transmission component two is connected to the input end of the transmission component three, and the output end of the transmission component three is connected to the input end of the steering component. The transmission component one is used to drive the movable end to move in the gas supply component two. When the movable end moves, the gas flows between the gas supply component two and the transmission component two. The transmission component two drives the steering component to rotate in a preset direction through the transmission component three.

[0011] Preferably, transmission assembly one includes a bevel gear platform, a bevel gear sleeve, and a lead screw two movably connected within the end platform. The bevel gear platform is detachably connected to the bevel gear disk, the tooth surface of the bevel gear sleeve meshes with the bevel gear platform, and the lead screw two is threaded into the threaded opening on the bevel gear sleeve. A drive motor can drive the bevel gear platform to rotate following the bevel gear disk, and the bevel gear platform drives the bevel gear sleeve to rotate. When the bevel gear sleeve rotates, the lead screw two moves within the end platform in a preset direction. The lead screw two is slidably connected to the end platform via a keyway. Gas delivery assembly two includes an air cylinder one installed within the end platform, an air delivery pipe two connected at one end to the air cylinder one, and a plunger one movably connected within the air cylinder one. The other end of the air delivery pipe two is connected to transmission assembly two. An energy-absorbing component is installed between the plunger one and the lead screw two. When the lead screw two moves, the energy-absorbing component deforms to absorb the energy. When the kinetic energy of the second lever reaches the threshold F3 after being absorbed by the energy-absorbing component, the first plunger moves inside the first air cylinder. The second transmission assembly includes the second air cylinder mounted on the slide, the second plunger movably connected inside the second air cylinder, and a rocker arm with one end connected to the second plunger. The other end of the second air supply pipe is connected to the second air cylinder, and the gas flows between the first and second air cylinders through the second air supply pipe. The third transmission assembly includes a rotating plate and a transmission disk movably connected to the slide, and a bevel gear head fixedly connected to the rotating plate. The other end of the rocker arm is movably connected to the eccentric position of the rotating plate. The transmission disk has a bevel tooth surface that meshes with the bevel gear head, and also has a steering worm wheel that meshes with the steering worm. The rocker arm is used to drive the rotating plate and the bevel gear head to rotate. When the bevel gear head rotates, the transmission disk drives the support plate to rotate through the steering worm.

[0012] Preferably, a closed module is installed on the bracket, and a gas supply component one is installed inside the inclined platform. The gas supply component one is connected to the closed module. When the slide moves between H2 and H3, the gas flows between the gas supply component one and the closed module. When the gas flows into the closed module, the closed module expands and covers the opening of the connecting pipe two.

[0013] Preferably, the enclosed module includes a side ring fixedly connected to the bracket and an airbag detachably installed on the inner wall of the side ring. A snap-fit ​​ring is fixedly connected to the airbag and snaps onto the side ring. The first gas delivery assembly includes an air hood installed on the inclined platform and a first gas delivery pipe connected at one end to the air hood. The other end of the first gas delivery pipe is connected to the airbag. When the slide moves between H2 and H3, the gas flows between the air hood and the airbag. When the gas flows into the airbag, the airbag expands and covers the opening of the second connecting pipe.

[0014] Preferably, an air curtain module is installed on the enclosed module. The air curtain module is used to deliver airflow to the open portion after the second connecting pipe is separated from the first connecting pipe. A signal unit is installed on the inclined platform. The signal unit is used to send signals to the control unit of the air curtain module. The air curtain module includes a duct and a turbine fan fixedly connected to the side ring, as well as an air outlet opened on the duct. The turbine fan outputs airflow through the duct at the open portion of the second connecting pipe. The signal unit includes a tension spring and a tension sensor installed between the inclined platform and the slider. When the slider moves, the tension sensor is used to detect the tension value of the tension spring. When the slider moves to position H3, the tension sensor detects the tension value of the tension spring as F4 and sends a signal to the control unit of the turbine fan.

[0015] A die-casting method, using a die-casting equipment as described above, includes the following steps: S1: When the flanges on connecting pipe 1 and connecting pipe 2 are closed, manually turn the crank handle to control the turntable and the front worm gear to rotate together. Use the meshing transmission between the front worm gear and the front worm to control the rotation of the inner flat gear, which in turn drives the gear ring to rotate. Then, use the meshing connection between the gear ring and the outer flat gear to control the rotation of all the outer flat gears and their locking parts until the straight part and the oblique straight part leave the flange. At this time, connecting pipe 1 and connecting pipe 2 are in a separable state, and the torque sensor detects that the torque value of the torsion spring is F2. S2: The torque sensor sends a signal to the drive motor, which outputs power to the bevel gear plate. The meshing transmission between the bevel gear plate and the bevel gear, as well as the meshing transmission between the bevel gear and the bevel gear seat, controls the rotation of the lead screw, causing the slider threaded on the lead screw and the slide block fixedly connected to it to move obliquely upward along the inclined platform, thereby causing the connecting pipe 1 mounted on the support plate to move away from the connecting pipe 2, achieving the effect of separating the connecting pipe 1 and the connecting pipe 2 from each other. As the drive motor outputs power to the bevel gear disk, the bevel gear platform also rotates with the bevel gear disk. The rotating bevel gear platform transmits power to the bevel gear sleeve, causing the lead screw two, which is threadedly connected to the bevel gear sleeve, to move in the axial direction of the air cylinder one, and absorbs the kinetic energy of the lead screw two through the energy-absorbing component. S3: When the slide moves from position H1 to position H2 and continues to move to position H3, at this time, connecting pipe one and connecting pipe two are separated by a certain distance, and at this time, the kinetic energy absorption of the energy-absorbing component reaches the threshold F3. As the slide continues to move, it begins to pressurize the air hood, causing the gas in the air hood to flow into the airbag through the first air supply pipe, causing the airbag to inflate. When the slide moves to position H3, the airbag inflates to its maximum size and covers the open part of the second connecting pipe. At the same time, the second lead screw transmits power to the first plunger through the energy-absorbing component, causing the first plunger to move inside the first air cylinder. The gas inside the first air cylinder flows into the second air cylinder through the second air supply pipe. As the pressure inside the second air cylinder increases, the second plunger moves and controls the rotating plate and bevel gear head to rotate continuously through the rocker arm. Through the meshing transmission action between the bevel gear head and the transmission plate and the meshing transmission action between the transmission plate and the steering worm, the support plate is controlled to rotate around the steering worm as the rotation axis, so that the connecting pipe one fixed to the support plate flips to adjust the angle. When the slide moves to the H3 position, the open part of the connecting pipe one flips to face upward. S4: When the slide moves to position H3, the tension sensor detects that the tension value of the tension spring is F4 and sends a signal to the control unit of the turbine fan. The turbine fan starts and delivers airflow through the air duct and air outlet, forming an air curtain at the opening of the connecting pipe 2.

[0016] The beneficial effects of this invention are: 1. Through the linkage design of the manual drive component and the signal unit, the real-time feedback of the rotation status of the locking component is realized. Combined with the preset direction movement control of the automatic drive component, the pipeline separation operation can be fully automated, avoiding the risk of manual operation near high-temperature equipment and reducing the safety hazards of personnel burns or molten metal splashes. 2. The detachable flange connection structure, combined with the inclined ramp design of the locking component, allows the flange to achieve a seal by gradually applying pressure through the inclined straight section when it is in place, and to quickly detach through the flat section when it is separated. Compared with the traditional flange bolt connection method, the disassembly time is reduced by more than 60%, and no tools are required, which significantly improves maintenance efficiency. 3. The base module integrates the mechanical transmission system of linkage component one and linkage component two. By delaying the power transmission through the energy-absorbing component and combining the flipping function of the steering component, the connecting pipe one is automatically adjusted to a vertical state after separation, preventing motion interference between pipes. 4. The separation action of the pipeline causes the air bladder of the sealing module to expand, forming a seal at the opening of the connecting pipe 2, preventing dust from entering and ensuring the purity of the conveyed molten metal. 5. The air curtain module is designed to prevent dust from entering through gaps caused by insufficient airbag expansion or aging, further ensuring the sealing effect at the opening of the connecting pipe 2.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-7 and Figures 10-18This invention provides an embodiment of a die-casting apparatus, comprising a molten metal holding furnace 1, a mold 2, a mold cavity 3 disposed within the mold 2, a pressure-applying component mounted on one side of the mold 2, a conveying pipe installed between the molten metal holding furnace 1 and the pressure-applying component, an electromagnetic pump 7 mounted on the conveying pipe, and a pressure-reducing component mounted on the mold 2. The electromagnetic pump 7 is used to convey raw materials from the molten metal holding furnace 1 to the pressure-applying component through the conveying pipe. The pressure-applying component is used to convey the raw materials into the mold cavity 3, and the pressure-reducing component is used to regulate the pressure within the mold cavity 3. The conveying pipe consists of two detachably connected pipes, one of which is connected to the pressure-applying component, and the other extends into the molten metal holding furnace 1. A flange 603 is provided at the connection point of the two pipes. A manual drive component is installed on one of the pipes, and a locking element is connected to the output end of the manual drive component. The manual drive component is used to drive the locking element closer to or away from the flange 603. When the locking element approaches and eventually abuts against the flange 603, the two pipes... The components are connected together. A base module is detachably mounted on the molten metal holding furnace 1. An automatic drive component is mounted on the base module. A sliding component is slidably connected to the base module. The sliding component is connected to the output end of the automatic drive component. The automatic drive component is used to drive the sliding component to move in a preset direction. A signal unit 1 is mounted on the manual drive component. When the locking element moves, the signal unit 1 sends a signal to the automatic drive component. A steering component is rotatably connected to the sliding component. The pipe inside the molten metal holding furnace 1 is mounted on the steering component. A linkage component 1 is mounted inside the base module. The input end of linkage component 1 is connected to the output end of the automatic drive component. An energy-absorbing element 1804 is mounted on linkage component 1. A linkage component 2 is mounted on the sliding component. The input end of linkage component 2 is connected to the output end of linkage component 1. The output end of linkage component 2 is connected to the steering component. The automatic drive component drives the steering component to rotate through linkage component 1 and linkage component 2. The energy-absorbing element 1804 is used to delay the power transmission in linkage component 1. It is worth noting that the diameter of the flange 603 at the junction of the two pipes is much larger than the diameter of the pipes, and in practical applications, a metal sealing ring can be set on the surface of the flange 603 to ensure sealing when they are fitted (as the locking part rotates onto the flange 603, it will create a squeezing effect on the two flanges 603, achieving a tight connection). During the die casting process, the upstream end of the electromagnetic pump 7 is immersed in the molten metal in the molten metal holding furnace 1 at an angle of about 45 degrees, and the molten metal in the molten metal holding furnace 1 is drawn upward from the upstream end of the electromagnetic pump 7 body. The electromagnetic pump 7 supplies the molten metal from the molten metal holding furnace 1 to the sleeve 4. The casting is performed by an injection operation. In this injection operation, the molten metal supplied to the sleeve 4 is squeezed by the top of the plunger and injected into the mold cavity 3. The inner circumference of the electromagnetic pump 7 body is made of ceramic.When a voltage is applied to the coil embedded in the electromagnetic pump 7 according to the injection control, the electromagnetic pump 7 uses electromagnetic force to draw molten metal upward. Other types of pumps can also be used, such as turbine pumps including rotors and positive displacement pumps including rotors.

[0021] Please see Figures 1-3 and Figure 10 In this embodiment, the pressure application component includes a sleeve 4 connected to the mold 2 at one end and a plunger 5 movably connected inside the sleeve 4. The plunger 5 can move inside the sleeve 4, and the sleeve 4 is connected to the mold cavity 3. When the plunger 5 moves inside the sleeve 4, the raw material flows between the sleeve 4 and the mold cavity 3. The pressure reduction component includes a shut-off valve 801 installed inside the mold 2, an air pipe connected to the shut-off valve 801 at one end, an on / off valve 802, a pressure reducing tank 803, and a vacuum pump 804 installed sequentially along the air pipe. The shut-off valve 801 is used to open or close the air pipe path between the mold cavity 3 and the on / off valve 802, and the on / off valve 802 is used to open or close the connection between the shut-off valve 801 and the pressure reducing tank 802. The air pipe path between the three sections; the delivery pipe includes connecting pipe one 601 and connecting pipe two 602, flange 603 is connected to the opposite ends of connecting pipe one 601 and connecting pipe two 602, the other end of connecting pipe one 601 extends into the molten metal holding furnace 1, and the other end of connecting pipe two 602 is connected to the pressure application component, the delivery pipe also includes a bracket 6021 connected to connecting pipe two 602; the base module includes an end platform 901 detachably mounted on the molten metal holding furnace 1 and a ramp 902 connected to one side of the end platform 901, the automatic drive component is used to drive the sliding component to move on the ramp 902, and to make the two pipes close or separate. To ensure the specified vacuum level in the mold cavity 3, the on / off valve 802 remains open during the injection operation, so that air in the mold cavity 3 is continuously extracted. Subsequently, after the top of the plunger 5 has moved completely to the end of the sleeve 4 (the electromagnetic pump 7 draws molten metal from the molten metal holding furnace 1 and delivers it to the sleeve 4 through connecting pipe 1 601 and connecting pipe 2 602), the opening and closing valve 802 closes and pressure is reduced. After the product in the mold cavity 3 solidifies, the mold 2 is removed to take out the product.

[0022] Please see Figures 1-9In this embodiment, the manual drive assembly includes a turntable 1001 rotatably connected to a bracket 6021, a front worm gear 1002 fixedly connected to the turntable 1001, a crank 1003 with one end connected to an eccentric position on the turntable 1001, a front worm 1004 movably connected to the bracket 6021, an internal flat gear 1005 fixedly connected to one end of the worm, a gear ring 1006 rotatably connected to the bracket 6021, and several external flat gears 1007. The front worm gear 1002... The gear ring 1006 is meshed with the front worm gear 1004. Both the inner and outer walls of the gear ring 1006 are provided with toothed structures. The inner flat gear 1005 meshes with the teeth on the inner wall of the gear ring 1006, and the outer flat gear 1007 meshes with the teeth on the outer wall of the gear ring 1006. When the crank handle 1003 is turned, the front worm wheel 1002 drives the front worm gear 1004 and the inner flat gear 1005 to rotate. The inner flat gear 1005 is used to drive the gear ring 1006 to rotate, and the gear ring 1006 is used to drive several outer flat gears 1007 to rotate. The locking element includes a straight portion 1101 fixedly connected to the external spur gear 1007 and an inclined straight portion 1102 connected to one side of the straight portion 1101. An inclined ramp structure exists between the straight portion 1101 and the inclined straight portion 1102. When the straight portion 1101 rotates closer to the flange 603, the ramp structure slides on the surface of the flange 603 until the inclined straight portion 1102 abuts against the flange 603. The signal unit includes a torsion spring and a torque sensor mounted on the external spur gear 1007. One end of the torsion spring is fixedly connected to the bracket 6021, and the other end is connected to the torque sensor, which detects the torque value of the torsion spring. When the external spur gear 1007 rotates until the inclined straight portion 1102 abuts against the flange 603, the torque sensor detects a torque value of F1 for the torsion spring. When the external spur gear 1007 rotates until the straight portion 1101 moves away from the flange 603, the torque sensor detects a torque value of F2 for the torsion spring. It is worth noting that in practical applications, the length and position of the crank handle 1003 are within the safe zone of the die-casting equipment, maintaining a certain distance from the molten metal holding furnace 1 and the pipeline, thus ensuring operational safety. Manually rotating the crank handle 1003 drives the locking element closer to or away from the flange 603. In this embodiment, the locking element adopts an inclined structure composed of a straight portion 1101 and a slanted straight portion 1102. When approaching the flange 603, the slanted straight portion 1102 slowly applies pressure to the surface of the flange 603, ultimately causing the two flanges 603 to fit together, thus securing the pipeline. Together with pipe 2, they form a complete conveying channel. In practical applications, the locking element can also adopt other structures with inclined surfaces, such as shuttle-shaped parts. The purpose is that the locking element gradually applies pressure to the flange 603 as it rotates. When the two flanges 603 are fully connected, the locking element rotates to a certain angle, and the torque sensor detects the torque value of the torsion spring as F1. When the locking element rotates away from the flange 603 (reaching the preset position), the torque sensor detects the torque value of the torsion spring as F2, and sends a signal to the automatic drive component to control the automatic separation of the two connecting pipes. The whole operation is very smooth.

[0023] Please see Figures 1-3 , Figure 10 and Figures 12-16 In this embodiment, the automatic drive assembly includes a drive motor 1401 mounted on the end plate 901, a bevel gear disk 1402 fixedly connected to the output end of the drive motor 1401, a bevel gear 1403 movably connected within the end plate 901, a bevel gear seat 1404 movably connected within the inclined platform 902, and a lead screw 1405. One end of the bevel gear seat 1404 is fixedly connected to one end of the lead screw 1405. The bevel gear 1403 has two bevel tooth surfaces, one of which meshes with the bevel gear disk 1402, and the other meshes with the bevel gear seat 1404. The drive motor 1401 drives the bevel gear disk 1402 to rotate. When the bevel gear disk 1402 rotates, it drives the lead screw to rotate via the bevel gear 1403 and the bevel gear seat 1404. The sliding assembly includes a slide block 1501 slidably connected to the inclined platform 902, a slider 1502 fixedly connected to the slide block 1501, and a support ring 1503. The support ring 1503 has a semi-circular ring structure and its center overlaps with the rotation center of the steering assembly. The slider 1502 is threadedly connected to the lead screw. When the lead screw rotates, it drives the slide block 1501 to move on the inclined platform 902. The steering assembly includes a support plate 1601 rotatably connected to the slide block 1501 at one end via a rotating shaft, a steering worm gear 1602 fixedly connected to the rotating shaft, and a support frame 1603 fixedly connected to the support plate 1601. The support frame 1603 is slidably connected inside the support ring 1503, and the other end of the support frame 1603 is detachably connected to the connecting pipe 601. The mechanical transmission of the drive motor 1401, lead screw 1405, etc., is mainly used to control the slide 1501 to move on the inclined platform 902 (moving obliquely along the pipe axis direction of the docking end of the connecting pipe 601 and the connecting pipe 602) after the locking parts are unlocked (after the locking parts leave the flange 603). In practical applications, the separation of the connecting pipe 601 and the connecting pipe 602 can also be controlled by direct cylinder drive, so that the electromagnetic pump 7 moves above the molten metal holding furnace 1.

[0024] Please see Figures 1-3 and Figures 10-18In this embodiment, the linkage component one includes a transmission component one and a gas supply component two installed in the end plate 901. The input end of the transmission component one is connected to the output end of the automatic drive component, and the energy absorption component 1804 is installed between the output end of the transmission component and the movable end of the gas supply component two. The linkage component two includes a transmission component two and a transmission component three installed on the slide 1501. The output end of the transmission component two is connected to the input end of the transmission component three, and the output end of the transmission component three is connected to the input end of the steering component. The transmission component one is used to drive the movable end to move in the gas supply component two. When the movable end moves, the gas flows between the gas supply component two and the transmission component two. The transmission component two drives the steering component to rotate in a preset direction through the transmission component three. The transmission assembly includes a bevel gear platform 1701, a bevel gear sleeve 1702, and a lead screw 1703, all movably connected within the end plate 901. The bevel gear platform 1701 is detachably connected to the bevel gear disk 1402. The tooth surface of the bevel gear sleeve 1702 meshes with the bevel gear platform 1701. The lead screw 1703 is threaded into the threaded opening on the bevel gear sleeve 1702. The drive motor 1401 can drive the bevel gear platform 1701 to rotate following the bevel gear disk 1402. The bevel gear platform 1701 drives the bevel gear sleeve 1702 to rotate. When the bevel gear sleeve 1702 rotates, the lead screw 1703 rotates within the end plate. The screw 1703 moves along a preset direction within the end panel 901, and the lead screw 1703 is slidably connected to the end panel 901 via a keyway. The second air supply assembly includes an air cylinder 1801 installed within the end panel 901, an air supply pipe 1802 connected at one end to the air cylinder 1801, and a plunger 1803 movably connected within the air cylinder 1801. The other end of the air supply pipe 1802 is connected to the transmission assembly. An energy-absorbing element 1804 is installed between the plunger 1803 and the lead screw 1703. When the lead screw 1703 moves, the energy-absorbing element 1804 deforms to absorb the energy from the lead screw 1703. When the kinetic energy absorbed by the energy-absorbing component 1804 reaches the threshold F3, the plunger 1803 moves within the air cylinder 1801; the transmission assembly 2 includes an air cylinder 2 1901 mounted on the slide 1501, a plunger 2 1902 movably connected within the air cylinder 2 1901, and a rocker arm 1903 with one end connected to the plunger 2 1902. The other end of the air supply pipe 2 1802 is connected to the air cylinder 2 1901, and gas flows between the air cylinder 1801 and the air cylinder 2 1901 through the air supply pipe 2 1802; the transmission assembly 3 includes a component movably connected to the slide... The rotating plate 2001 and transmission disk 2003 on 1501, as well as the bevel gear head 2002 fixedly connected to the rotating plate 2001, and the other end of the rocker arm 1903 is movably connected to the eccentric position of the rotating plate 2001. The transmission disk 2003 has a bevel tooth surface that meshes with the bevel gear head 2002, and also has a steering worm wheel that meshes with the steering worm 1602. The rocker arm 1903 is used to drive the rotating plate 2001 and the bevel gear head 2002 to rotate. When the bevel gear head 2002 rotates, the transmission disk 2003 drives the support plate 1601 to rotate through the steering worm 1602.The drive motor 1401 in the automatic drive assembly also serves to output power to control the rotation of the electromagnetic pump 7 and the connecting pipe 601. Through a series of mechanical transmissions, including fluid force drive, the pallet 1601 connected to the electromagnetic pump 7 is tilted upwards (see figure, which is a counterclockwise rotation, so that the electromagnetic pump 7 is perpendicular to the molten metal holding furnace 1, expanding the space and reducing maintenance obstacles). It is worth noting that the energy-absorbing element 1804 set in the gas supply assembly 2 serves to buffer and delay rotation (that is, after the drive motor 1401 controls the slide 1501 to move a certain distance, according to the attached figure). Figure 11 This can be set as stage H1-H2. Only then does the energy-absorbing component 1804 transmit power from the lead screw 1703 to the plunger 1803, causing the support plate 1601 to rotate. Under this operation, the rotation of the connecting pipe 601 occurs after the linear movement. At this time, the connecting pipe 601 and the connecting pipe 602 have already separated by a certain distance, and there will be no local collision interference between the pipe end and the connecting pipe 602 due to the rotation. The energy-absorbing component 1804 can be a compression spring or other elastic material, and its elastic modulus needs to be determined by experimental calculation.

[0025] Please see Figures 1-5 and Figures 7-9In this embodiment, a sealing module is installed on the bracket 6021, and a gas supply component 1 is installed in the inclined platform 902. The gas supply component 1 is connected to the sealing module. When the slide 1501 moves between H2 and H3, the gas flows between the gas supply component 1 and the sealing module. When the gas flows into the sealing module, the sealing module expands and covers the opening of the connecting pipe 2 602. The enclosed module includes a side ring 1201 fixedly connected to the bracket 6021 and an airbag 1203 detachably installed on the inner wall of the side ring 1201. A snap-fit ​​ring 1202 is fixedly connected to the airbag 1203 and snap-fits it onto the side ring 1201. The first gas delivery assembly includes an air cover 1301 installed on the inclined platform 902 and a first gas delivery pipe 1302 connected at one end to the air cover 1301. The other end of the first gas delivery pipe 1302 is connected to the airbag 1203. When the slide 1501 moves between H2 and H3, the gas flows between the air cover 1301 and the airbag 1203. When the gas flows into the airbag 1203, the airbag 1203 expands and covers the opening of the second connecting pipe 602. When the slide 1501 moves between H2 and H3, the air cover 1301 begins to compress (one end of the air cover 1301 is not connected to the slide 1501), and the airbag 1203 inflates (from the outside in, similar to a swimming ring). Because the connecting pipe 601 and the connecting pipe 602 are separated by a certain distance when the slide 1501 moves between H1 and H2, the airbag 1203 has sufficient space to expand and is not affected by the obstruction of the end of the connecting pipe 601. After fully expanding, it covers the open part of the connecting pipe 602 (because the open part of the connecting pipe 601 faces upwards, it is very easy for dust and impurities to enter, affecting the purity of the molten metal), preventing... When dust enters, conventional techniques typically involve adding a temporary cover to the connecting pipe 602. However, this requires bolts or clips for fixation, and the interface with the pipe is prone to tiny gaps in the sealing surface due to installation errors, thermal expansion and contraction, or vibration. This can lead to leakage of molten metal vapor or dust, affecting the safety of the process environment. In this embodiment, the airbag 1203 seal can fully fit the open edge of the connecting pipe 602, providing excellent sealing. The airbag 1203 uses fluororubber (FKM) or silicone rubber (VMQ) as its base material, and its operating temperature range is -20℃ to 300℃. It can withstand the ambient temperature around the molten metal holding furnace 1 in the die-casting workshop (usually ≤200℃) and has no risk of aging and cracking during long-term use.

[0026] Please see Figures 1-5 and Figure 9Based on further optimizations of this embodiment, an air curtain module is installed on the enclosed module. The air curtain module is used to deliver airflow to the open portion after the second connecting pipe 602 is separated from the first connecting pipe 601. A signal unit 2 is installed on the inclined platform 902. The signal unit 2 is used to send signals to the control unit of the air curtain module. The air curtain module includes a duct 2101 and a turbine fan 2103 fixedly connected to the side ring 1201, and an air outlet 2102 opened on the duct 2101. The turbine fan 2103 outputs airflow through the duct 2101 at the open portion of the second connecting pipe 602. The signal unit includes a tension spring and a tension sensor installed between the inclined platform 902 and the slider 1502. When the slider 1501 moves, the tension sensor is used to detect the tension value of the tension spring. When the slider 1501 moves to position H3, the tension sensor detects the tension value of the tension spring as F4 and sends a signal to the control unit of the turbine fan 2103. Because the airbag 1203 will deform to a certain extent after long-term use, and there may be gaps in the middle of the airbag 1203 due to insufficient expansion, the air curtain module can form a continuous air curtain on the surface of the airbag 1203 to further prevent dust from entering the connecting pipe 2 602 through the gap in the middle of the airbag 1203. (It is worth noting that the turbine fan 2103 only receives the signal to start when the slide 1501 moves to the H3 position. That is, after the connecting pipe 1 601 and the connecting pipe 2 602 are completely separated and the airbag 1203 is fully inflated, the turbine fan 2103 is in the off state in other states to avoid accidental start-up.)

[0027] Please see Figures 1-10 In this embodiment, the present invention provides a die-casting method using a die-casting device as described above, comprising the following steps: S1: When the flanges 603 on connecting pipe 1 (601) and connecting pipe 2 (602) are closed, manually turn the crank handle 1003 (Note: Before turning the crank handle 1003, confirm through the equipment control panel that the temperature of the molten metal holding furnace 1 has dropped to a safe range, generally ≤650℃, and ensure that the electromagnetic pump 7 has stopped working to avoid the risk of high-temperature molten metal splashing. Also, wear high-temperature resistant gloves and a protective mask during operation, and ensure that there are no non-operating personnel within 1 meter of the operating area). Control the turntable 1001 and the front worm gear 1002 to rotate together, using the meshing transmission between the front worm gear 1002 and the front worm 1004 to control the internal... The rotation of the spur gear 1005 drives the gear ring 1006 to rotate. The gear ring 1006 then meshes with the external spur gear 1007 to control the rotation of all external spur gears 1007 and their locking parts until the straight part 1101 and the oblique straight part 1102 leave the flange 603 (generally, the rotation angle of the locking part can be controlled within the range of 180°±10° to ensure that the straight part 1101 and the oblique straight part 1102 completely leave the flange 603, avoiding the pipes from being unable to separate due to insufficient rotation). At this time, the connecting pipe 1 601 and the connecting pipe 2 602 are in a separable state, and the torque sensor detects that the torque value of the torsion spring is F2. S2: The torque sensor sends a signal to the drive motor 1401, and the drive motor 1401 outputs power to the bevel gear disk 1402 (the speed is determined experimentally to ensure that the slide 1501 moves at a uniform speed of 2±0.5cm / s along the inclined platform 902, avoiding uneven force at the pipe connection due to excessive speed, and allowing observation of whether there is any molten metal residue in the pipe). Utilizing the meshing transmission between the bevel gear disk 1402 and the bevel gear 1403, as well as the meshing transmission between the bevel gear 1403 and the bevel gear seat 1404, the screw 1405 is controlled to rotate, causing the slider 1502 threaded onto the screw and the slide 1501 fixedly connected to it to move obliquely upward along the inclined platform 902, thereby causing the connecting pipe 601 mounted on the support plate 1601 to move away from the connecting pipe 602, achieving the effect of separating the connecting pipe 601 and the connecting pipe 602. As the drive motor 1401 outputs power to the bevel gear disk 1402, the bevel gear platform 1701 also rotates with the bevel gear disk 1402. The rotating bevel gear platform 1701 transmits power to the bevel gear sleeve 1702, causing the lead screw 1703, which is threadedly connected to the bevel gear sleeve 1702, to move in the axial direction of the air cylinder 1801, and the kinetic energy of the lead screw 1703 is absorbed by the energy-absorbing component 1804. S3: When the slide block 1501 moves from position H1 to position H2 and continues to move to position H3 (the moving time is best controlled within 8 to 12 seconds), at this time, the connecting pipe 1 601 and the connecting pipe 2 602 are separated by a distance, and at this time, the kinetic energy absorption of the energy-absorbing component 1804 reaches the threshold F3. As the slide 1501 continues to move, it begins to pressurize the air cover 1301, causing the gas in the air cover 1301 to flow into the airbag 1203 through the first air supply pipe 1302, causing the airbag 1203 to inflate. When the slide 1501 moves to position H3, the airbag 1203 inflates to its maximum and covers the open part of the second connecting pipe 602. Meanwhile, the second lead screw 1703 transmits power to the first plunger 1803 through the energy-absorbing component 1804, causing the first plunger 1803 to move inside the first air cylinder 1801. The gas inside the first air cylinder 1801 flows into the second air cylinder 1901 through the second air supply pipe 1802. As the pressure inside the second air cylinder 1901 increases, the second plunger 1902 moves and controls the rotating plate 2001 and the bevel gear head 2002 to rotate continuously through the rocker arm 1903. Through the meshing transmission action between the bevel gear head 2002 and the transmission plate 2003 and the meshing transmission action between the transmission plate 2003 and the steering worm gear 1602, the support plate 1601 is controlled to rotate around the steering worm gear 1602 as the rotation axis, so that the connecting pipe 601 fixed to the support plate 1601 flips to adjust the angle. When the slide 1501 moves to the H3 position, the open part of the connecting pipe 601 flips to face upward. S4: When the slide 1501 moves to position H3, the tension sensor detects that the tension value of the tension spring is F4 and sends a signal to the control unit of the turbine fan 2103. The turbine fan 2103 starts and delivers airflow through the air duct 2101 and the air outlet 2102, forming an air curtain at the opening of the connecting pipe 2 602. The air curtain speed should be controlled within the range of 7 to 8 m / s and the air volume should be 30 to 40 m³ / h to ensure that a stable and continuous air curtain is formed at the opening of the connecting pipe 2 602, effectively blocking dust and impurities from entering.

When the kinetic energy absorbed by the energy-absorbing component (1804) reaches the threshold F3, the first plunger (1803) moves in the first gas cylinder (1801). The transmission assembly 2 includes an air cylinder 2 (1901) mounted on a slide (1501), a plunger 2 (1902) movably connected inside the air cylinder 2 (1901), and a rocker arm (1903) with one end connected to the plunger 2 (1902). The other end of the air supply pipe 2 (1802) is connected to the air cylinder 2 (1901), and gas flows between the air cylinder 1 (1801) and the air cylinder 2 (1901) through the air supply pipe 2 (1802). The transmission assembly includes a rotating plate (2001) and a transmission disk (2003) movably connected to the slide (1501), and a bevel gear head (2002) fixedly connected to the rotating plate (2001). The other end of the rocker arm (1903) is movably connected to the eccentric position of the rotating plate (2001). The transmission disk (2003) has a bevel tooth surface that meshes with the bevel gear head (2002) and a steering worm wheel that meshes with the steering worm (1602). The rocker arm (1903) is used to drive the rotating plate (2001) and the bevel gear head (2002) to rotate. When the bevel gear head (2002) rotates, the transmission disk (2003) drives the support plate (1601) to rotate through the steering worm (1602).

The die-casting equipment according to claim 6, characterized in that: A closed module is installed on the bracket (6021), and a gas supply component one is installed in the inclined platform (902). The gas supply component one is connected to the closed module. When the slide (1501) moves between H2 and H3, the gas flows between the gas supply component one and the closed module. When the gas flows into the closed module, the closed module expands and covers the opening of the connecting pipe two (602).

8. The die-casting equipment according to claim 7, characterized in that: The closed module includes a side ring (1201) fixedly connected to the bracket (6021) and an airbag (1203) detachably installed on the inner wall of the side ring (1201). A snap ring (1202) is fixedly connected to the airbag (1203) and snaps and fixes it to the side ring (1201). The gas delivery assembly includes an air hood (1301) mounted on a ramp (902) and a gas delivery pipe (1302) with one end connected to the air hood (1301). The other end of the gas delivery pipe (1302) is connected to an air bladder (1203). When the slide (1501) moves between H2 and H3, the gas flows between the air hood (1301) and the air bladder (1203). When the gas flows into the air bladder (1203), the air bladder (1203) expands and covers the opening of the connecting pipe (602).

9. A die-casting equipment according to claim 8, characterized in that: An air curtain module is installed on the closed module. The air curtain module is used to deliver airflow to the open part after the second connecting pipe (602) is separated from the first connecting pipe (601). A signal unit two is installed on the inclined platform (902). The signal unit two is used to send signals to the control unit of the air curtain module. The air curtain module includes a duct (2101) and a turbine fan (2103) fixedly connected to the side ring (1201) and an air outlet (2102) opened on the duct (2101). The turbine fan (2103) outputs airflow through the duct (2101) at the opening of the connecting pipe two (602); The signal unit includes a tension spring and a tension sensor installed between the inclined plate (902) and the slider (1502). When the slider (1501) moves, the tension sensor is used to detect the tension value of the tension spring. When the slider (1501) moves to the H3 position, the tension sensor detects the tension value of the tension spring as F4 and sends a signal to the control unit of the turbine fan (2103).

10. A die-casting method, characterized in that: The method of using a die-casting equipment as described in claim 9 includes the following steps: S1: When the flanges (603) on connecting pipe 1 (601) and connecting pipe 2 (602) are closed, turn the crank (1003) by hand to control the turntable (1001) and the front worm gear (1002) to rotate together. Use the meshing transmission between the front worm gear (1002) and the front worm (1004) to control the rotation of the inner flat gear (1005), which in turn drives the gear ring (1006) to rotate. Then, use the meshing connection between the gear ring (1006) and the outer flat gear (1007) to control all the outer flat gears (1007) and their locking parts to rotate until the straight part (1101) and the oblique straight part (1102) leave the flange (603). At this time, connecting pipe 1 (601) and connecting pipe 2 (602) are in a separable state, and the torque sensor detects that the torque value of the torsion spring is F2. S2: The torque sensor sends a signal to the drive motor (1401), and the drive motor (1401) outputs power to the bevel gear disk (1402). By utilizing the meshing transmission between the bevel gear disk (1402) and the bevel gear (1403), as well as the meshing transmission between the bevel gear (1403) and the bevel gear seat (1404), the screw rod (1405) is controlled to rotate, so that the slider (1502) threaded on the screw and the slide seat (1501) fixedly connected to it move obliquely upward along the inclined platform (902), thereby causing the connecting pipe (601) installed on the support plate (1601) to move away from the connecting pipe (602), achieving the effect of separating the connecting pipe (601) and the connecting pipe (602) from each other; As the drive motor (1401) outputs power to the bevel gear disk (1402), the bevel gear platform (1701) also rotates with the bevel gear disk (1402). The rotating bevel gear platform (1701) transmits power to the bevel gear sleeve (1702), causing the lead screw two (1703) threadedly connected to the bevel gear sleeve (1702) to move in the axial direction of the air cylinder one (1801), and absorbs the kinetic energy of the lead screw two (1703) through the energy-absorbing component (1804). S3: When the slide (1501) moves from position H1 to position H2 and continues to move to position H3, at this time the first connecting pipe (601) and the second connecting pipe (602) are separated by a distance, and at this time the kinetic energy absorption of the energy-absorbing component (1804) reaches the threshold F3. As the slide (1501) continues to move, it begins to pressurize the air cover (1301), causing the gas in the air cover (1301) to flow into the airbag (1203) through the first air supply pipe (1302), causing the airbag (1203) to inflate. When the slide (1501) moves to position H3, the airbag (1203) inflates to its maximum and covers the open part of the second connecting pipe (602). Simultaneously, the second lead screw (1703) transmits power to the first plunger (1803) through the energy-absorbing component (1804), causing the first plunger (1803) to move inside the first air cylinder (1801). The gas inside the first air cylinder (1801) flows into the second air cylinder (1901) through the second air supply pipe (1802). As the pressure inside the second air cylinder (1901) increases, the second plunger (1902) moves, and controls the rotating plate (2001) and the bevel gear head (200) through the rocker arm (1903). 2) Continuously rotate, through the meshing transmission action of the bevel tooth head (2002) and the transmission disc (2003) and the meshing transmission action of the transmission disc (2003) and the steering worm (1602), control the pallet (1601) to rotate around the steering worm (1602) as the rotation axis, so that the connecting pipe (601) fixed to the pallet (1601) flips to adjust the angle. When the slide (1501) moves to the H3 position, the open part of the connecting pipe (601) flips to face upward. S4: When the slide (1501) moves to position H3, the tension sensor detects that the tension value of the tension spring is F4 and sends a signal to the control unit of the turbine fan (2103). The turbine fan (2103) starts and delivers airflow through the air duct (2101) and the air outlet (2102), forming an air curtain at the opening of the connecting pipe (602).
