Description

Technical Field

[0001] This invention relates to the field of die casting technology, and in particular to a die casting machine with a material collection function. Background Technology

[0002] A die-casting machine is a casting device used to fill a mold with molten metal under high pressure to manufacture parts. Its basic principle is to use high pressure to melt the metal, which is then filled and solidified through the cavity of the mold to obtain the desired part. Die-casting machines are widely used in the automotive, motorcycle, motor, electronics, communications, and hardware manufacturing industries. According to different classification standards, die-casting machines can be divided into different types. For example, according to the working position of the pressure chamber, they can be divided into vertical die-casting machines and horizontal die-casting machines; according to the degree of automation, they can be divided into manual die-casting machines and semi-automatic die-casting machines, etc.

[0003] Existing die-casting machines typically require separate filling of molten metal before each casting, resulting in low efficiency. After casting, the workpiece must be manually removed, which is dangerous. Furthermore, the significant impact forces experienced between the molds during casting affect workpiece quality. Therefore, a die-casting machine with a material collection function is proposed. Summary of the Invention

[0004] The present invention addresses the technical problems of existing die casting machines, which typically require separate filling of molten metal before each die casting, resulting in low efficiency. After die casting, the workpieces need to be manually removed, which is dangerous. Furthermore, the large impact forces between the molds during die casting can easily cause misalignment and affect the quality of the workpieces. The present invention provides a die casting machine with a material collection function.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A die-casting machine with material collection function includes a main body, a hot chamber die-casting mechanism, a synchronous limiting and vibration damping mechanism, and an automatic cooling and unloading mechanism;

[0007] A worktable is fixedly mounted on the top of the main body, and a hot melt chamber is fixedly mounted on the right side of the main body. Bases are fixedly mounted on the bottom of both the main body and the hot melt chamber. A left fixed platform is fixedly mounted on the top left side of the worktable, and a right fixed platform is fixedly mounted on the top right side of the worktable. The shapes and sizes of the left and right fixed platforms are matched, and both are perpendicular to the worktable. A hot chamber die-casting mechanism is positioned between the left and right fixed platforms, and a synchronous limiting and vibration damping mechanism is positioned between the hot chamber die-casting mechanism. An inner groove is formed inside the main body, and an automatic cooling and unloading mechanism is located inside the inner groove. During die casting, the molten metal inside the hot melt chamber is die-cast using the hot chamber die-casting mechanism. Simultaneously, the synchronous limiting and vibration damping mechanism limits and fixes the mold, reducing the impact on the mold during die casting. After die casting is completed, the workpiece can be removed and cooled using the automatic cooling and unloading mechanism.

[0008] Furthermore, the hot chamber die-casting mechanism includes several guide rods, which are respectively arranged parallel to each other between the four corners of the left fixed platform and the right fixed platform. The guide rods are perpendicular to the side walls of the left and right fixed platforms. A movable platform is slidably arranged in the middle of the guide rod. The bottom of the movable platform is slidably connected to the worktable via a slider. The slider extends through the worktable into the interior of the inner groove. A rotating disk is rotatably arranged on the left side of the rear side wall of the inner groove. A drive motor is connected to the center of the rotating disk. A rotating rod is rotatably connected to the front edge of the rotating disk. A movable rod is rotatably connected to the other end of the rotating rod. The movable rod is parallel to the guide rod. An upper sliding rod is fixedly arranged on the upper side of the other end of the movable rod. The top end of the upper sliding rod is fixedly connected to the slider. During die casting, a drive motor drives a rotating disk to rotate, causing the rotating rod connected to the edge of the disk to rotate as well. When the rotating rod rotates, it drives the movable rod to move left and right periodically in the horizontal direction. When the movable rod moves to the right, it drives the top slider to move to the right, causing the movable bar to move to the right along the guide rod.

[0009] Furthermore, a fixed mold is fixedly installed at the center of the left side wall of the right fixed platform. Several connecting rods are vertically installed on the side wall of the movable platform facing the right fixed platform. An outer sleeve is fitted on the right side of each connecting rod. A first spring is installed between the outer sleeve and the movable platform. A movable mold is fixedly connected between the outer sleeves through a fixing block. The position and size of the movable mold match those of the fixed mold. A die-casting groove is formed between the movable mold and the fixed mold. Protrusions are fixedly installed on the outer edge of the connection between the movable mold and the fixed mold. A drive rack is fixedly installed at the right end of the connecting rod. A slot is opened on the outer edge of the fixed mold. The right end of the drive rack extends through the outer edge of the movable mold into the interior of the slot. A trigger button is installed on the top inner side of the slot. The position of the trigger button matches that of the drive rack. When the moving platform moves to the right, it drives the connecting rod and the moving mold to move to the right until the moving mold comes into contact with the fixed mold. At this time, the moving mold continues to move to the right, causing relative movement between the connecting rod and the outer ring. The first spring is compressed, generating a thrust on the moving mold, so that the moving mold and the fixed mold always keep in close contact. When the connecting rod moves, it drives the drive rack to move towards the fixed mold until the drive rack penetrates deep into the groove. When the drive rack moves to the deepest part of the inner groove, it squeezes the trigger button. At this time, the moving mold is subjected to the greatest thrust.

[0010] Furthermore, a spray hole is provided at the center of the right side of the fixed mold, and a liquid inlet is provided at the center of the right fixed platform. The output end of the liquid inlet is connected to the input end of the spray hole, and the input end of the liquid inlet is connected to a liquid inlet pipe. An inner liquid tank is provided inside the hot melt chamber, and a heater is provided outside the hot melt chamber. The inner liquid tank is filled with molten metal, and a hydraulic chamber is provided inside the inner liquid tank. A piston is movably provided inside the hydraulic chamber, and an electric hydraulic rod is connected to the top of the piston. The electric hydraulic rod is fixedly connected to the top of the hot melt chamber through a mounting bracket. The electric hydraulic rod is electrically connected to the trigger button. A liquid outlet is provided at the bottom of the hydraulic chamber, and the liquid outlet is connected to the input end of the liquid inlet pipe. A heat insulation layer is fixedly provided on the outside of the liquid inlet pipe and the hydraulic chamber. A liquid inlet is provided at the center of the right side of the hydraulic chamber. When the trigger button is pressed, the electro-hydraulic rod extends, driving the piston at its bottom to move towards the bottom of the hydraulic chamber. This generates high pressure on the molten metal inside the hydraulic chamber, causing the molten metal to spray out through the outlet, then flow into the delivery hole through the inlet pipe, and finally be sprayed into the die-casting tank through the spray hole to perform die-casting on the workpiece. After die-casting is completed, the moving mold moves in the opposite direction. At this time, the drive rack disengages from the trigger button, causing the electro-hydraulic rod to reset and drive the piston to move upward. A negative pressure is generated inside the hydraulic chamber. When the piston moves above the inlet, the molten metal inside the inner tank is re-injected into the hydraulic chamber under the action of negative pressure. Through the above steps, continuous automatic filling of molten metal can be achieved, effectively improving die-casting efficiency.

[0011] Furthermore, the synchronous limiting and damping mechanism includes a transmission gear disposed inside the slot and rotatably connected to the rear sidewall of the slot. The transmission gear is located on the side of the drive rack facing the die-casting groove and meshes with the drive rack. A driven rack is meshed on the lower side of the transmission gear and slidably connected to the bottom of the slot. The driven rack is parallel to the drive rack. When the drive rack moves to the right, it drives the transmission gear meshing with it to rotate, causing the driven rack meshed on the other side of the transmission gear to move in the opposite direction.

[0012] Furthermore, a connecting rod is connected to the left end of the driven rack, away from the driving rack. The connecting rod is perpendicular to the driven rack, and a limit rod is fixedly provided at the other end of the connecting rod. The limit rod is parallel to the driven rack, and a limit hole is provided at the connection between the moving mold and the limit rod. The diameter and depth of the limit hole match the diameter and length of the limit rod. When the drive rack moves, it drives the connecting rod to move accordingly. When the connecting rod moves, it drives the limit rod to move accordingly, so that the limit rod is engaged in the limit groove during die casting. This reduces the vibration between the moving mold and the fixed mold during die casting, avoids deformation of the workpiece during die casting, and improves the die casting quality.

[0013] Furthermore, a sealing groove is provided at the connection between the moving mold and the fixed mold, and a sealing strip is provided inside the sealing groove, the sealing strip surrounding the die-casting groove. The sealing groove improves the sealing performance of the moving mold and the fixed mold during die casting, preventing the molten metal from overflowing under high pressure.

[0014] Furthermore, the automatic cooling and unloading mechanism includes a push rod, which is fixedly disposed on the top right side of the movable platform. The push rod is parallel to the guide rod. A mounting rod is fixedly disposed on the bottom right end of the push rod. Clamping jaws are symmetrically disposed on both sides of the bottom of the mounting rod. A second spring is connected between the tops of the clamping jaws. A wedge-shaped top block is fixedly disposed at the center of the top left side of the right fixed platform. An elastic clamping block is disposed on the bottom end of the clamping jaws facing the fixed mold. When the movable platform moves to the right, it drives the push rod to move to the right. When the push rod moves, it drives the mounting rod to move accordingly. When the mounting rod moves, it drives the clamping jaws on both sides of the bottom to move accordingly. When the clamping jaws come into contact with the wedge-shaped top block, they are pushed outward, causing the clamping jaws to separate during die casting. The second spring extends, generating a pulling force in the opposite direction. After die casting is completed, the mounting rod returns to its original position. At this time, the clamping jaws close under the pulling force of the second spring, driving the clamping block to move into the die casting tank to remove the workpiece.

[0015] Furthermore, a discharge port is provided on the lower side of the fixed mold, and a guide strip is vertically provided on the bottom edge of the discharge port. A discharge plate is slidably provided on the inner side of the guide strip, and a lifting rod is vertically provided on the bottom of the discharge plate. The top movable end of the lifting rod is rotatably connected to the bottom of the discharge plate. Several locking teeth are provided on the outer wall of the top movable end of the lifting rod. The top movable end of the lifting rod is threadedly connected to the bottom fixed end. A top plate is movably provided on the rear side wall of the inner groove. The top plate is located directly below the guide strip. The top plate is connected to the rear side wall of the inner groove through an electric telescopic rod. The telescopic frequency of the electric telescopic rod matches the rotation speed of the rotating disk. A sliding rod is vertically connected to the lower right end of the movable rod. A movable rack is vertically provided on the right end of the sliding rod. The movable rack is engaged with the top movable end of the lifting rod through the locking teeth. After die casting is completed, the movable rod moves to the left, driving the sliding rod to the left, which in turn causes the connected movable rack to move. When the movable rack moves to the left, it drives the movable end of the lifting rod that meshes with it to rotate. When the movable end of the lifting rod rotates, it moves upward along the threaded fixed end, causing the unloading plate to move upward along the guide bar until the unloading plate passes through the unloading port and moves to the bottom of the fixed mold. At this time, the workpiece is taken out by the gripper and falls onto the surface of the unloading plate under the action of gravity. When the movable rack moves to the right again, the lifting rod shortens, driving the unloading plate and the workpiece to move towards the bottom of the inner groove. When the unloading plate moves to the bottom of the top plate, the electric telescopic rod extends to unload the workpiece from the surface of the unloading plate. Through the above steps, automatic unloading of the workpiece can be achieved, and damage to the workpiece caused by excessive height when it falls can be avoided.

[0016] Furthermore, a drive bevel gear is arranged around the outer edge of the rotating disk, and a driven bevel gear is meshed with the left side of the drive bevel gear. A rotating shaft is connected to the center of the left side of the driven bevel gear. A heat dissipation hole is opened on the upper left side of the main body. The left end of the rotating shaft extends into the interior of the heat dissipation hole. Several blades are arranged on the left sidewall of the rotating shaft. A drive wheel is arranged at the center of the rear sidewall of the rotating disk. Transmission rollers are arranged on both sides of the bottom of the inner groove. A driven wheel is arranged at the center of the left transmission roller. A transmission chain is fitted between the drive wheel and the driven wheel. A conveyor belt is fitted between the transmission rollers. The conveyor belt is located below the top plate. After the workpiece is pushed out of the feeding plate, it falls onto the surface of the conveyor belt. When the rotating disc rotates, it drives the drive wheel to rotate. When the drive wheel rotates, it drives the driven wheel to rotate through the transmission chain meshing with it. When the driven wheel rotates, it drives the transmission roller to rotate, which in turn causes the conveyor belt to move, transporting the workpiece from the surface of the conveyor belt to the outside of the main body. When the rotating disc rotates, it drives the drive bevel gear on its outer edge to rotate, which in turn drives the driven bevel gear to rotate. When the driven bevel gear rotates, it drives the rotating shaft to rotate, which causes the blades inside the heat dissipation holes to rotate, generating airflow to cool the workpiece. This achieves automatic cooling of the workpiece during the conveying process, facilitating the next step of processing.

[0017] The beneficial effects of this invention are:

[0018] 1. The die-casting machine with material collection function of the present invention can die-cast the molten metal inside the hot chamber through the hot chamber die-casting mechanism, and at the same time realize the continuous filling of the molten metal. During die-casting, the mold is limited and fixed by the synchronous limiting and vibration damping mechanism to reduce the impact on the mold during die-casting. After die-casting is completed, the workpiece can be automatically removed and cooled by the automatic cooling unloading mechanism.

[0019] 2. The die-casting machine with material collection function of the present invention, by setting a limiting rod, can drive the connecting rod to move when the transmission rack moves, and drive the limiting rod to move when the connecting rod moves, so that the limiting rod is locked into the inside of the limiting groove during die casting, thereby reducing the vibration between the moving mold and the fixed mold during die casting, avoiding deformation of the workpiece during die casting, and improving the die casting quality.

[0020] 3. The die-casting machine with material collection function of the present invention, by being equipped with a feeding plate, allows the movable rod to move to the left after die-casting, driving the sliding rod to move to the left, causing the movable rack connected to it to start moving. When the movable rack moves to the left, it drives the movable end of the lifting rod that meshes with it to start rotating. When the movable end of the lifting rod rotates, it moves upward along the threaded fixed end, causing the feeding plate to move upward along the guide bar until the feeding plate passes through the feeding port and moves to the bottom of the fixed mold. At this time, the workpiece is taken out by the gripper and falls onto the surface of the feeding plate under the action of gravity. When the movable rack moves to the right again, the lifting rod shortens, driving the feeding plate and the workpiece to move towards the bottom of the inner groove. When the feeding plate moves to the bottom of the top plate, the electric telescopic rod extends to unload the workpiece from the surface of the feeding plate. Through the above steps, automatic feeding of the workpiece can be achieved, and damage to the workpiece caused by excessive height when it falls can be avoided.

[0021] 4. The die-casting machine with material collection function of the present invention, by being equipped with blades, can drive the drive wheel to rotate when the rotating disk rotates. When the drive wheel rotates, it drives the driven wheel to rotate through the transmission chain meshing with it. When the driven wheel rotates, it drives the transmission roller to rotate, thereby causing the conveyor belt meshing with it to move and transport the workpiece on the surface of the conveyor belt to the outside of the main body. When the rotating disk rotates, it drives the drive bevel gear on its outer edge to rotate, causing the driven bevel gear meshing with it to rotate. When the driven bevel gear rotates, it drives the rotating shaft to rotate, causing the blades inside the heat dissipation holes to rotate, generating airflow to cool the workpiece, thereby realizing automatic cooling of the workpiece during the conveying process, which facilitates the further processing of the workpiece.

[0026] The following will describe the concept and technical effects of the present invention clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of the present invention.

[0027] like Figure 1-3 As shown, a die-casting machine with material collection function includes a main body 1, a hot chamber die-casting mechanism, a synchronous limiting and vibration damping mechanism, and an automatic cooling and unloading mechanism.

[0028] A workbench 2 is fixedly mounted on the top of the main body 1, and a hot melt chamber 4 is fixedly mounted on the right side of the main body 1. Bases 3 are fixedly mounted on the bottom of both the main body 1 and the hot melt chamber 4. A left fixed platform 5 is fixedly mounted on the top left side of the workbench 2, and a right fixed platform 7 is fixedly mounted on the top right side of the workbench 2. The shapes and sizes of the left and right fixed platforms 5 and 7 are matched, and both are perpendicular to the workbench 2. A hot chamber die-casting mechanism is positioned between the left and right fixed platforms 5 and 7, and a synchronous limiting and vibration damping mechanism is positioned between the hot chamber die-casting mechanism. An inner groove is formed inside the main body 1, and an automatic cooling and unloading mechanism is located inside the inner groove. During die casting, the molten metal inside the hot melt chamber 4 is die-cast using the hot chamber die-casting mechanism. Simultaneously, the mold is limited and fixed by the synchronous limiting and vibration damping mechanism to reduce the impact on the mold during die casting. After die casting is completed, the workpiece can be removed and cooled by the automatic cooling and unloading mechanism.

[0029] The hot chamber die-casting mechanism includes several guide rods 8, which are arranged parallel to each other between the four corners of the left fixed platform 5 and the right fixed platform 7. The guide rods 8 are perpendicular to the side walls of the left fixed platform 5 and the right fixed platform 7. A movable platform 6 is slidably arranged in the middle of the guide rod 8. The bottom of the movable platform 6 is slidably connected to the worktable 2 through a slider. The slider extends through the worktable 2 into the interior of the inner groove. A rotating disk 13 is rotatably arranged on the left side of the rear side wall of the inner groove. A drive motor is connected to the center of the rotating disk 13. A rotating rod 17 is rotatably connected to the front edge of the rotating disk 13. A movable rod 18 is rotatably connected to the other end of the rotating rod 17. The movable rod 18 is parallel to the guide rods 8. An upper sliding rod 19 is fixedly arranged on the upper side of the other end of the movable rod 18. The top end of the upper sliding rod 19 is fixedly connected to the slider. During die casting, the rotating disk 13 is driven by a drive motor to start rotating, which causes the rotating rod 17 connected to the edge of the rotating disk 13 to rotate accordingly. When the rotating rod 17 rotates, it drives the movable rod 18 to move left and right periodically in the horizontal direction. When the movable rod 18 moves to the right, it drives the top slider to move to the right, which causes the movable bar to move to the right along the guide rod 8.

[0030] A fixed mold 10 is fixedly installed at the center of the left side wall of the right fixed platform 7. Several connecting rods 11 are vertically installed on the side wall of the movable platform 6 facing the right fixed platform 7. An outer sleeve 41 is fitted on the right side of the connecting rod 11. A first spring 40 is installed between the outer sleeve 41 and the movable platform 6. A movable mold 9 is fixedly connected between the outer sleeve 41 by a fixing block. The movable mold 9 matches the position and size of the fixed mold 10. A die-casting groove 26 is formed between the movable mold 9 and the fixed mold 10. A protrusion is fixedly installed on the outer edge of the connection between the movable mold 9 and the fixed mold 10. A drive rack 42 is fixedly installed on the right end of the connecting rod 11. A slot 43 is opened on the outer edge of the fixed mold 10. The right end of the drive rack 42 extends through the outer edge of the movable mold 9 into the interior of the slot 43. A trigger button 44 is installed on the top inner side of the slot 43. The position of the trigger button 44 matches the drive rack 42. When the movable platform 6 moves to the right, it drives the connecting rod 11 and the moving mold 9 to move to the right until the moving mold 9 comes into contact with the fixed mold 10. At this time, the moving mold 9 continues to move to the right, causing relative movement between the connecting rod 11 and the outer ring 41. The first spring 40 is compressed, generating a pushing force on the moving mold 9, so that the moving mold 9 and the fixed mold 10 always remain in close contact. When the connecting rod 11 moves, it drives the drive rack 42 to move towards the fixed mold 10 until the drive rack 42 penetrates into the interior of the slot 43. When the drive rack 42 moves to the deepest part of the inner slot, it squeezes the trigger button 44. At this time, the moving mold 9 receives the greatest pushing force.

[0031] A spray hole 27 is provided at the center of the right side of the fixed mold 10, and a liquid inlet 28 is provided at the center of the right fixed platform 7. The output end of the liquid inlet 28 is connected to the input end of the spray hole 27. The input end of the liquid inlet 28 is connected to a liquid inlet pipe 29. An inner liquid tank 32 is provided inside the hot melt chamber 4, and a heater is provided outside the hot melt chamber 4. The inner liquid tank 32 is filled with molten metal, and a hydraulic chamber 33 is provided inside the inner liquid tank 32. The hydraulic chamber 33 is movably arranged inside. There is a piston 34, and an electric hydraulic rod 31 is connected to the top of the piston 34. The electric hydraulic rod 31 is fixedly connected to the top of the hot melt chamber 4 through a mounting bracket. The electric hydraulic rod 31 is electrically connected to the trigger button 44. The bottom of the hydraulic chamber 33 has an outlet 36, which is connected to the input end of the inlet pipe 29. The inlet pipe 29 and the outside of the hydraulic chamber 33 are fixedly provided with a heat insulation layer 30. The right middle part of the hydraulic chamber 33 has an inlet 35. When the trigger button 44 is squeezed, the electric hydraulic rod 31 extends, driving the piston 34 at its bottom to move towards the bottom of the hydraulic chamber 33. This generates high pressure on the molten metal inside the hydraulic chamber 33, causing the molten metal to spray out through the outlet 36. Then, it flows into the delivery hole 28 through the inlet pipe 29, and finally into the die-casting tank 26 through the spray hole 27 to perform die-casting on the workpiece. After die-casting is completed, the moving mold 9 moves in the opposite direction. At this time, the drive rack 42 disengages from the trigger button 44, causing the electric hydraulic rod 31 to reset and drive the piston 34 to move upward. A negative pressure is generated inside the hydraulic chamber 33. When the piston 34 moves above the inlet 35, the molten metal inside the inner liquid tank 32 is re-injected into the hydraulic chamber 33 under the action of negative pressure. Through the above steps, continuous automatic filling of molten metal can be achieved, effectively improving die-casting efficiency.

[0032] The synchronous limiting and vibration damping mechanism includes a transmission gear 45, which is disposed inside the slot 43 and rotatably connected to the rear side wall of the slot 43. The transmission gear 45 is located on the side of the drive rack 42 facing the die-casting groove 26 and meshes with the drive rack 42. A driven rack 46 is meshed on the lower side of the transmission gear 45 and slidably connected to the bottom of the slot 43. The driven rack 46 is parallel to the drive rack 42. When the drive rack 42 moves to the right, it drives the transmission gear 45 to rotate, causing the driven rack 46 meshed on the other side of the transmission gear 45 to move in the opposite direction.

[0033] A connecting rod is connected to the left end of the driven rack 46, away from the driving rack 42. The connecting rod is perpendicular to the driven rack 46. A limit rod 47 is fixedly provided at the other end of the connecting rod. The limit rod 47 is parallel to the driven rack 46. A limit hole is provided at the connection between the moving mold 9 and the limit rod 47. The diameter and depth of the limit hole match the diameter and length of the limit rod 47. When the drive rack moves, it drives the connecting rod to move accordingly. When the connecting rod moves, it drives the limit rod 47 to move accordingly, so that the limit rod 47 is engaged in the limit groove during die casting. This reduces the vibration between the moving mold 9 and the fixed mold 10 during die casting, avoids deformation of the workpiece during die casting, and improves the die casting quality.

[0034] A sealing groove 48 is provided at the connection between the moving mold 9 and the fixed mold 10. A sealing strip is provided inside the sealing groove 48, and the sealing strip surrounds the die-casting groove 26. By providing the sealing groove 48, the sealing performance of the moving mold 9 and the fixed mold 10 during die casting can be improved, preventing the molten metal from overflowing under high pressure.

[0035] The automatic cooling and unloading mechanism includes a push rod 12, which is fixedly disposed on the top right side of the movable platform 6. The push rod 12 is parallel to the guide rod 8. A mounting rod 49 is fixedly disposed at the bottom right end of the push rod 12. Claws 50 are symmetrically disposed on both sides of the bottom of the mounting rod 49. A second spring 51 is connected between the tops of the claws 50. A wedge-shaped top block 53 is fixedly disposed at the center of the top left side of the right fixed platform 7. An elastic clamping block 52 is disposed on the side of the bottom end of the claws 50 facing the fixed mold 10. When the movable table 6 moves to the right, it drives the top rod 12 to move to the right. When the top rod 12 moves, it drives the mounting rod 49 to move accordingly. When the mounting rod 49 moves, it drives the jaws 50 on both sides of the bottom to move accordingly. When the jaws 50 move and come into contact with the wedge-shaped top block 53, they are pushed outward, causing the jaws 50 to separate during die casting. The second spring 51 extends, generating a pulling force in the opposite direction. When die casting is completed, the mounting rod 49 returns to its original position. At this time, the jaws 50 close under the pulling force of the second spring 51, driving the clamping block 52 to move into the die casting tank 26 to remove the workpiece.

[0036] The fixed mold 10 has a discharge port 37 on its lower side. A guide strip 39 is vertically arranged along the bottom edge of the discharge port 37. A discharge plate is slidably arranged on the inner side of the guide strip 39. A lifting rod 22 is vertically arranged at the bottom of the discharge plate. The top movable end of the lifting rod 22 is rotatably connected to the bottom of the discharge plate. Several locking teeth are provided on the outer wall of the top movable end of the lifting rod 22. The top movable end and the bottom fixed end of the lifting rod 22 are threadedly connected. The rear side of the inner groove A top plate 38 is movably provided on the wall, and the top plate 38 is located directly below the guide strip 39. The top plate 38 is connected to the rear side wall of the inner groove through an electric telescopic rod. The telescopic frequency of the electric telescopic rod is matched with the rotation speed of the rotating disk 13. A sliding rod 20 is vertically connected to the lower right end of the movable rod 18. A movable rack 21 is vertically provided on the right end of the sliding rod 20. The movable rack 21 is engaged with the top movable end of the lifting rod 22 through the locking teeth. After die casting is completed, the movable rod 18 moves to the left, driving the sliding rod 20 to move to the left, causing the movable rack 21 connected to it to start moving. When the movable rack 21 moves to the left, it drives the movable end of the lifting rod 22 that meshes with it to start rotating. When the movable end of the lifting rod 22 rotates, it moves upward along the threaded fixed end, causing the unloading plate to move upward along the guide bar 39 until the unloading plate passes through the unloading port 37 and moves to the bottom of the fixed mold 10. At this time, the workpiece is taken out by the gripper 50 and falls onto the surface of the unloading plate under the action of gravity. When the movable rack 21 moves to the right again, the lifting rod 22 shortens, driving the unloading plate and the workpiece to move towards the bottom of the inner groove. When the unloading plate moves to the bottom of the top plate 38, the electric telescopic rod extends to unload the workpiece from the surface of the unloading plate. Through the above steps, automatic unloading of the workpiece can be achieved, and damage to the workpiece caused by excessive height when it falls can be avoided.

[0037] A drive bevel gear 14 is arranged around the outer edge of the rotating disk 13. A driven bevel gear 15 is meshed with the left side of the drive bevel gear 14. A rotating shaft is connected to the center of the left side of the driven bevel gear 15. A heat dissipation hole is opened on the upper left side of the main body 1. The left end of the rotating shaft extends into the interior of the heat dissipation hole. Several blades 16 are arranged on the left side wall of the rotating shaft. A drive wheel is arranged at the center of the rear side wall of the rotating disk 13. Transmission rollers 23 are arranged on both sides of the bottom of the inner groove. A driven wheel 24 is arranged at the center of the left transmission roller 23. A transmission chain 25 is sleeved between the drive wheel and the driven wheel 24. A conveyor belt is sleeved between the transmission rollers 23. The conveyor belt is located below the top plate 38. After the workpiece is pushed out of the feeding plate, it falls onto the surface of the conveyor belt. When the rotating disk 13 rotates, it drives the drive wheel to start rotating. When the drive wheel rotates, it drives the driven wheel 24 to start rotating through the transmission chain 25 meshing with it. When the driven wheel 24 rotates, it drives the transmission roller 23 to start rotating, thereby causing the conveyor belt to start moving and transporting the workpiece on the surface of the conveyor belt to the outside of the main body 1. When the rotating disk 13 rotates, it drives the drive bevel gear 14 on its outer edge to start rotating, which in turn drives the driven bevel gear 15 to start rotating. When the driven bevel gear 15 rotates, it drives the rotating shaft to start rotating, which causes the blades 16 inside the heat dissipation holes to start rotating, generating airflow to cool the workpiece, thereby achieving automatic cooling of the workpiece during the conveying process, which facilitates the further processing of the workpiece.

[0038] Working principle: During die casting, the drive motor drives the rotating disk 13 to rotate, causing the rotating rod 17 connected to the edge of the rotating disk 13 to rotate accordingly. When the rotating rod 17 rotates, it drives the movable rod 18 to move periodically left and right in the horizontal direction. When the movable rod 18 moves to the right, it drives the top slider to move to the right, causing the movable bar to move to the right along the guide rod 8. When the movable table 6 moves to the right, it drives the connecting rod 11 and the moving mold 9 to move to the right until the moving mold 9 abuts against the fixed mold 10. At this time, the moving mold 9 continues to move to the right, causing relative movement between the connecting rod 11 and the outer ring 41. The first spring 40 is compressed, generating a pushing force on the moving mold 9, so that the moving mold 9 and the fixed mold 10 always remain in close contact. When the connecting rod 11 moves, it drives the drive rack 42 to move towards the fixed mold 10 until the drive rack 42 penetrates into the interior of the groove 43. When the drive rack 42 moves to the deepest part of the inner groove... When the trigger button 44 is squeezed, the moving mold 9 experiences the greatest thrust. When the trigger button 44 is squeezed, the electric hydraulic rod 31 extends, driving the piston 34 at its bottom to move towards the bottom of the hydraulic chamber 33. This generates high pressure on the molten metal inside the hydraulic chamber 33, causing the molten metal to spray out along the outlet 36, then flow into the delivery hole 28 through the inlet pipe 29, and finally spray into the die-casting tank 26 along the spray hole 27 to perform die-casting on the workpiece. After die-casting is completed, the moving mold 9 moves in the opposite direction. At this time, the drive rack 42 disengages from the trigger button 44, causing the electric hydraulic rod 31 to reset and drive the piston 34 to move upward. A negative pressure is generated inside the hydraulic chamber 33. When the piston 34 moves above the inlet 35, the molten metal inside the inner liquid tank 32 is re-injected into the hydraulic chamber 33 under the action of negative pressure. Through the above steps, continuous automatic filling of molten metal can be achieved, effectively improving die-casting efficiency.

[0039] When the drive rack 42 moves to the right, it drives the transmission gear 45 that meshes with it to start rotating, causing the driven rack 46 connected to the other side of the transmission gear 45 to move in the opposite direction. When the transmission rack moves, it drives the connecting rod to move accordingly. When the connecting rod moves, it drives the limiting rod 47 to move accordingly, so that the limiting rod 47 is locked into the limiting groove during die casting, thereby reducing the vibration between the moving mold 9 and the fixed mold 10 during die casting, avoiding deformation of the workpiece during die casting, and improving the quality of die casting. The sealing groove 48 can improve the sealing performance of the moving mold 9 and the fixed mold 10 during die casting, preventing the molten metal from overflowing under high pressure.

[0040] When the movable table 6 moves to the right, it drives the top rod 12 to move to the right. The top rod 12 then drives the mounting rod 49 to move accordingly. The mounting rod 49 then drives the grippers 50 on both sides of the bottom to move. When the grippers 50 contact the wedge-shaped top block 53, they are pushed outwards, causing them to separate during die casting. The second spring 51 extends, generating a pulling force in the opposite direction. After die casting is complete, the mounting rod 49 returns to its original position. At this time, the grippers 50 close under the pulling force of the second spring 51, driving the clamping block 52 to move towards the workpiece formed inside the die casting tank 26, removing the workpiece. After die casting is complete, the movable rod 18 moves to the left, driving the sliding rod 20 to move to the left, causing the connected movable rack 21 to begin moving. The movable rack 21 moves towards... When the movement is to the left, the movable end of the lifting rod 22 that is engaged with it begins to rotate. When the movable end of the lifting rod 22 rotates, it moves upward along the threaded fixed end, causing the unloading plate to move upward along the guide bar 39 until the unloading plate passes through the unloading port 37 and moves to the bottom of the fixed mold 10. At this time, the workpiece is taken out by the gripper 50 and falls onto the surface of the unloading plate under the action of gravity. When the movable rack 21 moves to the right again, the lifting rod 22 shortens, causing the unloading plate and the workpiece to move towards the bottom of the inner groove. When the unloading plate moves to the bottom of the top plate 38, the electric telescopic rod extends to unload the workpiece from the surface of the unloading plate. Through the above steps, automatic unloading of the workpiece can be achieved, and damage to the workpiece caused by excessive height when it falls can be avoided.

[0041] After the workpiece is pushed out of the feeding plate, it falls onto the surface of the conveyor belt. When the rotating disk 13 rotates, it drives the drive wheel to start rotating. When the drive wheel rotates, it drives the driven wheel 24 to start rotating through the transmission chain 25 meshing with it. When the driven wheel 24 rotates, it drives the transmission roller 23 to start rotating, thereby causing the conveyor belt to start moving and transporting the workpiece on the surface of the conveyor belt to the outside of the main body 1. When the rotating disk 13 rotates, it drives the drive bevel gear 14 on its outer edge to start rotating, which in turn drives the driven bevel gear 15 to start rotating. When the driven bevel gear 15 rotates, it drives the rotating shaft to start rotating, which causes the blades 16 inside the heat dissipation holes to start rotating, generating airflow to cool the workpiece, thereby achieving automatic cooling of the workpiece during the conveying process, which facilitates the further processing of the workpiece.
