Description

Technical Field

[0001] This invention relates to the field of metal casting technology, and in particular to a continuous casting apparatus for metal parts. Background Technology

[0002] Metal casting is involved in the metal processing and manufacturing industry. Metal casting requires continuous casting equipment to form metal billets and irregularly shaped metal parts. Continuous casting equipment is widely used in the metallurgical, machinery manufacturing, and hardware processing industries. However, traditional metal casting equipment still has the following shortcomings when casting metal parts:

[0003] First, existing conventional continuous casting equipment has the problem of fragmented structural layout and independent driving of each functional unit. The steps of mold conveying, mold lifting, and cooling docking need to be driven separately, which makes the metal casting process extremely complicated. At the same time, the mold conveying, mold lifting, and cooling docking devices occupy a lot of space, increasing the maintenance and operating costs of the equipment and increasing the casting time. In addition, the direct injection of high-temperature molten metal into room-temperature molds can easily cause defects such as cracks and shrinkage cavities in the castings due to the large temperature difference, which seriously affects the casting quality.

[0004] Secondly, during the casting process of metal parts, molten metal slag is prone to dripping and accumulating, and sticking to the end face of the melting vessel. The falling slag not only pollutes the working environment, but also affects the subsequent mold docking accuracy and the purity of the molten liquid pouring. In addition, conventional molds and positioning frames are mostly assembled by bolt fixing, which is cumbersome to disassemble and assemble, and is not conducive to the quick replacement, cleaning and maintenance of molds.

[0005] In view of the many shortcomings of existing technologies, there is an urgent need to design a continuous casting device for metal parts that is compact in structure, synchronized in action, and can automatically complete the integrated operation of conveying, preheating, casting, cooling and slag removal. Summary of the Invention

[0006] This invention relates to a continuous casting apparatus for metal parts. During operation, an electric motor drives a conveyor belt and positioning plate to transport the mold structure to its position below the molten shell. A hydraulic cylinder pushes a drive rack downwards, which, through gears, a rotating shaft, and rack transmission, simultaneously drives a lifting frame upwards, lifting the mold to fit against the bottom of the molten shell. Simultaneously, a belt drive rotates a second rotating shaft, causing a protective plate to unfold outwards, while a scraper simultaneously removes residual slag from the bottom of the molten shell. A driven rack moves upwards, causing a preheating cover to fall under its own weight, automatically covering the mold and automatically energizing the heating wires for preheating. The drive rack moves downwards, causing an extrusion rod to push against a guide sleeve, ensuring precise alignment between the connecting sleeve and the air inlet of the sealing shell, facilitating the circulation and cooling of the cooling airflow. After casting and cooling, the hydraulic cylinder resets, returning all mechanisms to their original positions, and the mold is conveyed out by the conveyor belt, repeating the cycle to achieve automated continuous casting of metal parts.

[0023] This invention provides a continuous casting apparatus for metal parts, which has the following advantages:

[0024] This invention features an integrated drive mechanism to achieve continuous casting of metal parts. It uses a hydraulic cylinder as a single power source and drives the mold lifting, protective plate opening and closing, preheating hood lifting and lowering, and drainage sleeve docking through rack, pinion, rotating shaft and belt. The actions are linked and run synchronously without the need for multiple additional drive components, simplifying the overall structure and reducing manufacturing costs and energy consumption.

[0025] Specifically, the present invention sets up a conveying mechanism in conjunction with a positioning plate to achieve continuous and stable conveying of the mold structure. The positioning plate and the positioning frame are quickly engaged by positioning blocks and positioning slots, which can realize the quick alignment and installation of the mold structure, as well as quick separation and disassembly, making it convenient for mold cleaning, replacement and demolding of metal parts, and making assembly, inspection and maintenance convenient and efficient.

[0026] Specifically, the mold is preheated evenly by the preheating cover and heating wire, which effectively avoids cracking defects caused by excessive temperature difference between the molten metal and the cold mold, and greatly improves the yield of metal casting. At the same time, the preheating cover slides up and down with precise guidance. After it moves into place, the conductive rod and the adapter automatically connect and are powered on, eliminating the need for manual wiring.

[0027] Specifically, the mold structure uses a sealed shell with a locking rod and a support spring to achieve automatic locking and positioning, effectively preventing the sealed shell from shifting during the casting process; the sealed shell is equipped with a wave-shaped connecting flow groove, which, together with the air inlet and exhaust port, forms a circulating air channel, which can quickly remove heat from the mold and metal parts, resulting in high cooling efficiency, effectively shortening the casting cycle, and adapting to the needs of continuous production.

[0028] Specifically, the bottom of the smelting shell is equipped with a protective plate, guide strips and scraper structure. The protective plate can shield and protect the outlet of the smelting shell to prevent the molten liquid from dripping, hardening and accumulating. During the sliding of the protective plate, the scraper can automatically scrape off the residual slag at the bottom of the shell to avoid slag accumulation affecting the casting purity and normal operation of the equipment. At the same time, the hidden groove storage design can protect and compensate for the scraper and extend the service life of the parts.

[0029] Specifically, the flow-guiding sleeve and the docking sleeve adopt a spring elastic fit structure, which can achieve automatic and precise docking with the air inlet of the sealing shell. The external cooler can achieve forced circulation cooling, further improving the cooling rate and cooling uniformity, and ensuring the consistency of metal part forming quality.

[0030] In addition, the machine is highly automated and can simultaneously complete mold conveying, precise positioning, mold lifting, mold preheating, molten metal pouring, circulating cooling, component reset and continuous cyclic operation with little manual intervention and low labor intensity. At the same time, the disassembly, cleaning and maintenance process is simple and the parts are easy to replace, making it suitable for continuous casting production of large batches of metal parts.

[0063] This invention proposes a continuous casting device for metal parts, comprising: a frame 100, the upper end face of which is provided with a fixedly connected ear plate 120, a first vertical rod 130, a second vertical rod 140, and a third vertical rod 150; the ear plate 120, the first vertical rod 130, and the second vertical rod 140 are configured as one unit, and the third vertical rod 150 is configured as two units; an electric motor 210 is fixedly connected at a corner of the frame 100; two rotatably connected rollers 220 are installed on the side of the frame 100; the drive shaft of the electric motor 210 is fixedly connected to one of the rollers 220; two conveyor belts 230 are installed between the two rollers 220; a sliding gap is left between the two conveyor belts 230; a set of evenly distributed first positioning plates 240 are installed between the two conveyor belts 230; a set of bolt mounting holes are formed inside the first positioning plates 240; and bolt mounting holes are formed according to... In practice, matching bolts need to be installed. After the bolts are installed, the first positioning plate 240 is stabilized. The electric motor 210, roller 220, conveyor belt 230, and first positioning plate 240 work together to form the conveying mechanism 200. Specifically, the electric motor 210 drives the roller 220 to rotate, and the roller 220 drives the conveyor belt 230 and the first positioning plate 240 to run smoothly. The first positioning plate 240 can stably position and support the mold structure 400, ensuring that the mold structure 400 is stably transported to different processing areas. The conveying mechanism 200 realizes the continuous transport of the mold structure 400, providing a stable transport step for continuous casting of metal parts and improving the casting efficiency of metal parts. At the same time, the spacing design of the conveyor belt 230 facilitates the passage of the subsequent lifting frame 700 without affecting the coordinated work of each component. A fixedly connected positioning rod 110 is installed on one side of the frame 100. A sliding hole corresponding to the positioning rod 110 is opened on one side of the lifting frame 700. The positioning rod 110 passes through the interior of the sliding hole. A driven rack 710 is fixedly connected on one side of the lifting frame 700. The inner side of the driven rack 710 is parallel to the side of the frame 100. Specifically, the positioning rod 110 guides and positions the lifting frame 700, and works with the driven rack 710 to prevent the lifting frame 700 from shifting or tilting when moving up and down, so that the lifting frame 700 can rise and fall smoothly, and the lifting frame 700 can accurately dock with the mold structure 400. At the same time, it ensures that the driven rack 710 and the gear of the first rotating shaft 640 are accurately meshed.

[0064] In this embodiment, a preheating cover 310 is slidably connected between the first vertical rod 130 and the second vertical rod 140. A set of fixedly connected insulation plates 320 are installed on the side of the preheating cover 310. A heating wire 330 is installed on each side of the preheating cover 310, and an insulation plate 320 is installed on the outer side of each heating wire 330.

A set of slots is opened on the side of the insulation plate 320, and the buckles 3101 extend into the slots. Specifically, the heating wire 330 heats the preheating cover 310, thereby uniformly preheating the casting mold 450 covered by the preheating cover 310. This prevents cracks caused by excessive temperature difference when molten metal is injected into the cold casting mold 450, thus improving the casting quality of the metal parts. The insulation plate 320 reduces heat loss and improves preheating efficiency. It also facilitates the positioning, disassembly, and protection of the heating wire 330, making it easier to maintain and replace. The clip 3101 enables quick positioning of the insulation plate 320, facilitating its installation.

[0065] In this embodiment, a positioning frame 410 is installed inside the frame 100. A fixedly connected sealing housing 440 is installed at the upper end of the positioning frame 410. A set of docking rods is provided at the bottom of the sealing housing 440. A set of docking grooves corresponding to the docking rods are opened at the corners of the positioning frame 410. The docking rods extend into the docking grooves. The sealing housing 440 and the positioning frame 410 are precisely and stably docked with the docking rods. Four symmetrically distributed sliding holes are opened inside the positioning frame 410. Locking rods 420 are installed through the sliding holes. A fixedly connected connecting plate 430 is installed between two parallel locking rods 420. A support spring is installed on the outside of the locking rod 420. A retaining ring is provided on the outer side of the locking rod 420. A support spring is located on one side of the retaining ring. The support spring pushes the locking rod 420 inward. A locking groove corresponding to the locking rod 420 is opened on the connecting rod of the sealing housing 440. One side of the locking rod 420 extends into the locking groove. Specifically, the support spring pushes the locking rod 420 into the locking groove of the connecting rod, realizing the automatic locking of the positioning frame 410 and the sealing housing 440. The connecting plate 430 facilitates the simultaneous operation of the two locking rods 420, making it convenient for the quick assembly and disassembly of the sealing housing 440 and preventing the sealing housing 440 from shifting during the casting process. A casting mold 450 is installed inside the sealing housing 440. The positioning frame 410, locking rod 420, connecting plate 430, sealing housing 440, and casting mold 450 cooperate with each other to form a mold structure. The structure 400; a set of flow channels are respectively opened on the outer side and bottom of the sealing shell 440. The flow channels have a wave structure and are interconnected. An air inlet is opened on one side of the sealing shell 440 and an exhaust port is opened on the other side of the sealing shell 440. The air inlet and exhaust port are connected to the flow channels. Specifically, the sealing shell 440 protects and seals the edge of the casting mold 450.

At the same time, it is convenient to quickly separate the first positioning plate 240 and the positioning frame 410. Specifically, the positioning blocks of the positioning frame 410 cooperate with the positioning grooves to realize the quick positioning and docking of the first positioning plate 240 and the positioning frame 410, improve the assembly efficiency of the first positioning plate 240 and the positioning frame 410, and facilitate the quick separation of the mold structure 400 and the conveying mechanism 200 after casting, which is convenient for subsequent cleaning and replacement of the casting mold 450 and demolding of metal parts.

[0066] In at least one embodiment, a smelting shell 500 is fixedly connected between the third vertical rods 150. A smelter 510 is fixedly connected to the upper end of the smelting shell 500. A protective plate 520 is installed at the bottom of the smelting shell 500. A guide strip 5201 is fixedly connected to the upper end face of the protective plate 520. A set of positioning grooves is formed on the side of the guide strip 5201. The positioning grooves have an arc structure. A sliding groove corresponding to the guide strip 5201 is formed at the bottom of the smelting shell 500. The guide strip 5201 extends into the interior of the sliding groove. Specifically, the protective plate 520 can be used for unused... The bottom of the molten metal shell 500 is protected to prevent molten metal from falling or hardening at the discharge port. A guide bar 5201, in conjunction with a sliding groove, allows the protective plate 520 to slide stably and smoothly at the bottom of the molten metal shell 500. Simultaneously, the guide bar 5201 and sliding groove provide vertical positioning for the protective plate 520, ensuring its stable unfolding and retraction, thus guaranteeing the safety and stability of the metal casting process. The upper end of the guide bar 5201 has a set of meshing teeth, and a fixedly connected gear is installed on the outer side of the second rotating shaft 900. The gear meshes with the meshing teeth of the guide bar 5201, providing… The second rotating shaft 900 drives the gear to rotate, which in turn moves the guide bar 5201, causing the protective plate 520 to automatically unfold and retract under force, eliminating the need for manual operation. This automation of the lifting device ensures the protective plate 520 is fully unfolded during casting and fully retracted during non-casting operations, without affecting the operation of other components. A hidden groove with a rectangular structure is provided on one side of the protective plate 520. A second positioning plate 5202 with a sliding connection is installed in the hidden groove. A set of fixedly connected scrapers 5203 is installed at the upper end of the second positioning plate 5202, and a set of supports is installed at the bottom of the scrapers 5203. The spring supports the second positioning plate 5202 and the scraper 5203 upwards elastically.

Specifically, the support spring pushes the scraper 5203 to make slight contact with the bottom of the melting shell 500. When the protective plate 520 slides, the scraper 5203 can automatically scrape off the residual metal slag at the bottom of the melting shell 500, avoiding slag accumulation that affects the purity of subsequent casting. The hidden groove can store and protect the positioning plate and the scraper 5203 and provide automatic compensation, extending the service life of the scraper 5203.

A slidably connected lifting frame 700 is installed inside the frame 100. A vertical push rod is provided in the middle of the lifting frame 700. A sliding hole corresponding to the push rod is provided in the middle of the first positioning plate 240. The push rod of the lifting frame 700 and the sliding hole of the first positioning plate 240 are aligned. A docking groove corresponding to the push rod of the lifting frame 700 is provided at the bottom of the casting mold 450. When the lifting frame 700 moves upward, it will drive the upper end of the push rod to engage in the docking groove. Specifically, when the lifting frame 700 moves upward, the push rod of the lifting frame 700 passes through the sliding hole and engages in the casting mold. The docking groove of mold 450 enables stable docking between lifting frame 700 and casting mold 450. Lifting frame 700, in conjunction with push rod, smoothly lifts casting mold 450 upwards, automatically aligning it with the bottom of melting shell 500, ensuring smooth injection of molten metal into casting mold 450. Push rod, in conjunction with docking groove, also serves a positioning function, preventing displacement of casting mold 450 during lifting. A rotatably connected roller 1401 is installed at the upper end of the second vertical rod 140. A wire hole is opened at the upper end of the second vertical rod 140. A rope stabilizing hole is opened on the sliding block on the other side of preheating cover 310. A wire hole is opened at the upper end of driven rack 710 to connect the second vertical rod 140. The rope is installed and secured inside the threaded hole of the driven rack 710 and the driven rack 70. A set of clamping plates 70101 near the threaded hole is located at the upper end of the driven rack 710. A set of inclined blocks is located inside the clamping plates 70101. Specifically, the rollers 1401 reduce friction when the rope slips, while ensuring smooth rope pulling. The rope connects the driven rack 710 and the preheating cover 310, enabling linkage between the lifting of the driven rack 710 and the lifting of the preheating cover 310. When the driven rack 710 moves downward, it pulls the preheating cover 310 upward; when it moves upward, it releases the rope, causing the preheating cover 310 to fall. No additional driving components are needed, simplifying the structure. The inclined blocks of the clamping plates 70101 further clamp and secure the rope, preventing... The rope is prevented from loosening or falling off, ensuring that the preheating cover 310 and the lifting frame 700 move synchronously, thus improving the smoothness of the continuous casting process. A sliding hole is opened inside the first vertical rod 130 and the second vertical rod 140 respectively. Two sliding blocks are provided on the side of the preheating cover 310, and the sliding blocks extend into the sliding holes. A conductive rod 340 is installed through the inside of one of the sliding blocks. The conductive rod 340 and the heating wire 330 are electrically connected. A fixedly connected adapter 350 is installed at the bottom of the first vertical rod 130. The preheating cover 310, buckle 3101, insulation plate 320, heating wire 330, conductive rod 340, and adapter 350 cooperate with each other to form the preheating structure 300.A set of bolt mounting holes is provided on one side of the adapter 350. Matching bolts are installed inside the bolt mounting holes to complete the fixed installation of the adapter 350. A conductive groove corresponding to the conductive rod 340 is provided inside the adapter 350. When the preheating cover 310 moves downward, the bottom of the conductive rod 340 is inserted into the conductive groove, completing the automatic electrical connection between the conductive rod 340 and the adapter 350. Specifically, the sliding block of the preheating cover 310 cooperates with the sliding hole to realize the smooth up and down movement of the preheating cover 310, ensuring that the preheating cover 310 accurately and stably covers the mold structure 400. The automatic electrical connection between the conductive rod 340 and the adapter 350 eliminates the need for manual wiring, realizing automatic power-on preheating after the preheating cover 310 moves into place, thus automating the lifting device.

[0068] Specifically, a drive rack 620 is fixedly connected to the bottom of the push rod of the hydraulic cylinder 610, and a first rotating shaft 640 is rotatably connected to one side of the frame 100. The hydraulic cylinder 610, drive rack 620, pressing rod 630, and first rotating shaft 640 cooperate to form a drive mechanism 600. A drive gear is installed on the outer side of the first rotating shaft 640. The first rotating shaft 640 meshes with the drive rack 620 and the driven rack 710 respectively. The drive rack 620 and the driven rack 710 are staggered vertically. Specifically, the hydraulic cylinder 610 controls the drive rack 620 to move up and down, and the drive gear meshes with the first rotating shaft 640. The moving shaft 640, in conjunction with the driven rack 710, moves synchronously to achieve automatic lifting and lowering of the lifting frame 700. Simultaneously, it drives the pressing rod 630 to move up and down, enabling a single power source to drive multiple components in coordinated operation, simplifying the device structure and reducing energy consumption. A slidingly connected drainage sleeve 800 is installed through the ear plate 120. Inside the drainage sleeve 800, a slidingly connected docking sleeve 810 is installed. The docking sleeve 810 has a cylindrical stepped structure, and a support spring is installed on its outer side, elastically supporting the docking sleeve 810 outwards. A support spring is also installed on the outer side of the drainage sleeve 800. The support spring pushes the drain sleeve 800 outward. A friction ring is provided on the outer surface of the drain sleeve 800, and a wedge is provided at the bottom of the extrusion rod 630. The friction ring and the wedge of the extrusion rod 630 are aligned. Specifically, the support spring provides elastic support for the docking sleeve 810 and the drain sleeve 800 respectively. After the extrusion rod 630 moves downward, it cooperates with the wedge and friction ring to extrude and drive the drain sleeve 800 inward, allowing the docking sleeve 810 to automatically and precisely dock with the air inlet of the sealing shell 440, improving docking efficiency and sealing effect at the docking position, preventing airflow leakage, and ensuring smooth flow of cooling air; one of the melting shells 500 A transverse rotating hole is opened on the side, and a second rotating shaft 900 is installed inside the rotating hole for rotatable connection. A pulley is installed on one side of the first rotating shaft 640 and the second rotating shaft 900 respectively, and a belt is installed between the two pulleys. The belt drives the first rotating shaft 640 and the second rotating shaft 900. When the first rotating shaft 640 rotates, it drives the second rotating shaft 900 to rotate. No additional drive components are required, which simplifies the structure of the device, reduces manufacturing and maintenance costs, and ensures smooth transmission. This allows the lifting of the lifting frame 700 and the unfolding of the protective plate 520 to be synchronized, improving the efficiency of the coordinated work of each component and ensuring a smooth continuous casting process.

[0069] In at least one embodiment, the hydraulic cylinder 610 pushes the drive rack 620 downward, at which time the first rotating shaft 640 rotates under force. Then, the lifting frame 700 moves upward in cooperation with the driven rack 710. The push rod of the lifting frame 700 passes through the first positioning plate 240 at the bottom of the melting shell 500. Then, the lifting frame 700, in cooperation with the push rod, lifts the mold structure 400 at the bottom of the melting shell 500 upward, so that the casting mold 450 and the bottom of the melting shell 500 come into contact. At the same time, the second rotating shaft 900 rotates in cooperation with the belt. The second rotating shaft 900 controls the protective plate 520 to move outward and unfold. During this process, the rope between the preheating cover 310 and the driven rack 710 loosens, and the preheating cover 310 moves downward by its own weight to cover the corresponding mold structure 400. During this process, the driving rack 620 drives the extrusion rod 630 to move downward. The inclined block at the bottom of the extrusion rod 630 pushes the guide sleeve 800 inward. At this time, the docking sleeve 810 automatically docks with the cast mold structure 400, and the docking sleeve 810 connects with the air inlet of the sealing shell 440.

[0070] Example 2, based on Example 1, such as Figures 1-15 As shown, an external cooler is required, and a drain pipe is installed between the cooler and the drain sleeve 800.

[0071] Example 3, based on Example 1, such as Figures 1-15 As shown, an insulation layer is added inside the molten shell 500 to reduce heat loss from the molten liquid, save energy, and at the same time ensure the stability of the molten liquid temperature and improve the consistency of metal casting.

[0072] The working principle of this embodiment:

[0073] When using the continuous casting device, first fix the entire device to the designated work area through the mounting structure at the bottom of the frame 100, assemble the mold structure 400, fix the casting mold 450 inside the sealing housing 440, align the docking rod at the bottom of the sealing housing 440 with the docking groove of the positioning frame 410, at this time the locking rod 420 automatically engages with the locking groove of the docking rod under the action of the support spring, thereby locking the sealing housing 440 and the positioning frame 410; if the mold structure 400 needs to be disassembled later, the locking rods 420 on both sides can be pulled synchronously through the connecting plate 430 to unlock;

[0074] The assembled mold structure 400 is snapped onto the first positioning plate 240 through the positioning groove at the bottom of the positioning frame 410, so as to realize the quick docking of the mold structure 400 and the conveying mechanism 200.

[0075] The external cooler is connected to the flow sleeve 800 through the flow pipe, and the metal raw material to be cast is added into the melter 510.

[0076] Start the electric motor 210. The electric motor 210 drives the roller 220 to rotate, which in turn drives the conveyor belt 230 and the first positioning plate 240 to run smoothly. The mold structure 400 containing the casting mold 450 is transported to the bottom of the melting shell 500. After reaching the designated position, the electric motor 210 is turned off, and the conveying of the casting mold 450 is stopped.

[0077] The hydraulic cylinder 610 is activated, which pushes the drive rack 620 downward. The drive rack 620 drives the first rotating shaft 640 to rotate. The first rotating shaft 640 drives the lifting frame 700 to move upward through gear meshing with the driven rack 710. The push rod of the lifting frame 700 passes through the sliding hole of the first positioning plate 240 and engages with the docking groove at the bottom of the casting mold 450. It continues to move upward to lift the mold structure 400, so that the casting mold 450 fits against the bottom of the melting shell 500.

[0078] As the lifting frame 700 moves upward, the first rotating shaft 640 drives the second rotating shaft 900 to rotate via a belt. The gear on the outside of the second rotating shaft 900 meshes with the guide bar 5201, driving the protective plate 520 to unfold outward. During the unfolding process, the scraper 5203 contacts the bottom of the melting shell 500 under the action of the support spring, scraping away the residual metal slag at the bottom. At the same time, the driven rack 710 moves upward, loosening the rope. The preheating cover 310 moves downward by its own weight, and the sliding block moves smoothly down along the sliding holes of the first vertical rod 130 and the second vertical rod 140 until it precisely covers the mold structure 400. At this time, the bottom of the conductive rod 340 is inserted into the conductive groove of the adapter 350 to achieve automatic electrical connection. The heating wire 330 is energized to uniformly preheat the casting mold 450.

[0079] After the casting mold 450 is preheated to the specified temperature, the melter 510 injects the molten metal into the casting mold 450. During the injection process, the sealing shell 440 provides a sealing and protective function. At the same time, the drive rack 620 moves downward, causing the extrusion rod 630 to move downward. The inclined block at the bottom of the extrusion rod 630 presses the friction ring of the guide sleeve 800, causing the guide sleeve 800 to move inward. Under the action of the support spring, the docking sleeve 810 automatically and precisely docks with the air inlet of the sealing shell 440. The cooler is turned on, and the cooling airflow passes through the guide pipe, the guide sleeve 800, and the docking sleeve 810 into the wave-shaped flow groove of the sealing shell 440. The airflow forms a circulation through the air inlet and exhaust port, which accelerates the cooling speed of the casting mold 450 and the metal parts, and shortens the casting cycle.

[0080] After the metal part is cooled and formed in the casting mold 450, the melter 510 and cooler are closed, the hydraulic cylinder 610 is reset, the rack 620 is driven to move upward, causing the first rotating shaft 640 to rotate in the opposite direction. The driven rack 710 and the lifting frame 700 move downward synchronously. The push rod of the lifting frame 700 disengages from the docking groove of the casting mold 450, and the mold structure 400 falls back onto the first positioning plate 240 of the conveying mechanism 200. At the same time, the second rotating shaft 900 rotates in the opposite direction, causing the protective plate 520 to retract inward to protect the bottom of the melting shell 500. When the driven rack 710 moves downward, it pulls the rope. The rope drives the preheating cover 310 to move upward through the roller 1401, disengaging it from the mold structure 400. The conductive rod 340 disengages from the adapter 350, and the heating wire 330 is de-energized. The extrusion rod 630 moves upward, and the drain sleeve 800 and the docking sleeve 810 are reset under the action of the support spring. The docking sleeve 810 is disconnected from the sealing shell 440.

[0081] The electric motor 210 is restarted, and the conveying mechanism 200 transports the mold structure 400 containing the formed metal parts to the next process. At the same time, the new, assembled mold structure 400 is transported to the bottom of the melting shell 500. The above steps are repeated to achieve continuous casting of metal parts.

[0082] Disassemble the mold structure in step 400. Pull the locking rod 420 through the connecting plate 430 to unlock the sealing housing 440 and the positioning frame 410, take out the formed metal part, clean the residual slag inside the casting mold 450, and replace the casting mold 450 if necessary.

[0083] Regularly clean the residual slag on the scraper 5203, check the elasticity of the support spring, and replace it in time if the elasticity is insufficient; if the heating wire 330 is damaged, disassemble the insulation plate 320 and replace it; regularly clean the debris on the conveyor belt 230 and the first positioning plate 240 to keep the conveying mechanism 200 running smoothly.
