[0001] This utility model belongs to the technical field of cold chamber die casting machines, and specifically relates to a feeding device for a cold chamber die casting machine. Background Technology

[0002] A cold chamber die casting machine is a type of die casting machine in which the injection chamber and injection punch are not immersed in molten metal, but a certain amount of molten metal is poured into the injection chamber and then injected. The injection method of a vertical cold chamber die casting machine is vertically placed.

[0003] Chinese patent application number 202122827464.8 discloses a feeding mechanism for a cold chamber die-casting machine, including a support, a worktable, vertical plates, a rotating shaft, an adjusting plate, a storage box, support plates, a horizontal plate, a drive mechanism, and a feeding mechanism. The top of the support is connected to the bottom of the worktable, and the bottoms of the two sets of vertical plates are connected to the top of the worktable. The rotating shaft is rotatably mounted between the two sets of vertical plates via bearings. The adjusting plate is mounted on the rotating shaft, and a counterweight is provided at the left end of the adjusting plate. The bottom of the storage box is connected to the top of the adjusting plate, and a feed inlet is provided at the left part of the top of the storage box. The right part of the top of the storage box is connected to the bottom of the discharge pipe. The bottoms of the two sets of support plates are connected to the top of the worktable, and the tops of the two sets of support plates are connected to the bottom of the horizontal plate. The feeding mechanism is mounted on the worktable. The drive mechanism includes a servo motor, a guide rod, a lead screw, a vertical plate, a moving plate, a drum, a gear, a rack, and a guide rope.

[0004] In the aforementioned patent, the material inside the storage tank is injected into the injection chamber of the die-casting machine through the conveying pipe. During the injection process, when the conveying pipe is displaced due to force, it can easily affect the material feeding operation. In addition, the material inside the storage tank is poured into the funnel and then fed through the conveying pipe. However, when a large amount of material accumulates inside the funnel, the material can easily block the conveying pipe, affecting the material feeding effect. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a feeding device for a cold chamber die-casting machine, characterized by stable material receiving and unobstructed material discharge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a cold chamber die casting machine, including a worktable, a rotating mechanism at one end of the upper part of the worktable, a feeding mechanism at the other end of the upper part of the worktable, a storage box fixedly connected above the rotating mechanism, a mounting frame fixedly connected above the worktable and around the rotating mechanism and the feeding mechanism, an inclined mechanism between the mounting frame and the rotating mechanism, a stabilizing receiving component below the feeding mechanism, and a clearing component on the side wall of the mounting frame corresponding to the position of the feeding mechanism.

[0007] Preferably, the stabilizing receiving assembly includes an overlap plate, an elastic bellows, an external flange, and an extension. An overlap plate is provided below the feeding mechanism. An elastic bellows is fixedly connected to one end of the overlap plate near the feeding mechanism. An external flange is fixedly connected to one end of both the feeding mechanism and the elastic bellows that are close to each other. Extensions are provided at both ends of the overlap plate.

The upper two ends of the overlapping plate are fixedly connected to the slide rail, the slide rod is slidably connected inside the slide rail, a clamping frame is fixedly connected to one end of the slide rod, and a clamping screw is threadedly connected to both sides of the clamping frame. An elastic pad is fixedly connected to the ends of the two clamping screws that are close to each other.

[0009] Preferably, the stabilizing receiving assembly further includes a limiting frame, an L-shaped rod, a connecting spring, and a support rod. L-shaped rods are fixedly connected to the side wall of the workbench on both sides of the overlapping plate. Support rods are slidably connected inside the L-shaped rods. A connecting spring is fixedly connected between the L-shaped rods and the support rods. A limiting frame is fixedly connected to the side wall of the overlapping plate at the position corresponding to the L-shaped rods.

[0010] Preferably, the unblocking assembly includes a return spring, a moving groove, a drive plate, an unblocking rod, a motor bracket, a drive motor, and an eccentric wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a stable material receiving component. The worktable is moved and overlapped onto the cold chamber die-casting machine. The support rod moves inward into the L-shaped rod, and the movement of the support rod compresses the connecting spring. After the support rod moves away from the limiting frame, the overlapping plate moves towards the injection chamber. The movement of the overlapping plate causes the elastic bellows to stretch. Then, the slide rod moves along the slide rail, and the movement of the slide rod causes the clamping frame to move. After the clamping frame moves and fits against the two side walls of the injection chamber, the clamping screw is rotated, causing it to rotate and move along the clamping frame. The rotation of the clamping screw causes the elastic pad to rotate and move. After the elastic pad moves and fits against the side wall of the injection chamber, the rotation of the clamping screw is stopped, ensuring the stability of the placement of the elastic bellows, thereby ensuring the stability of the material feeding into the injection chamber.

[0014] 2. This utility model is equipped with a dredging component. After the material inside the storage box is injected into the feeding mechanism, the drive motor on the motor bracket is started. The drive motor rotates, which drives the eccentric wheel to rotate. The rotation of the eccentric wheel drives the drive plate to move along the moving groove. The movement of the drive plate drives the dredging rod and the return spring to stretch. With the cooperation of the eccentric wheel and the return spring, the dredging rod can move up and down reciprocatingly. During the up and down reciprocating motion of the dredging rod, the material inside the feeding mechanism can be dredged, avoiding blockage of the feeding mechanism and affecting the feeding operation of the cold chamber die-casting machine.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5The present invention provides the following technical solution: a feeding device for a cold chamber die casting machine, including a worktable 4, a rotating mechanism 7 is provided at one end of the upper part of the worktable 4, a feeding mechanism 5 is provided at the other end of the upper part of the worktable 4, a storage box 6 is fixedly connected above the rotating mechanism 7, a mounting frame 1 is fixedly connected above the worktable 4 and around the rotating mechanism 7 and the feeding mechanism 5, an inclined mechanism 2 is provided between the mounting frame 1 and the rotating mechanism 7, a stable receiving component 8 is provided below the feeding mechanism 5, and a clearing component 3 is provided on the side wall of the mounting frame 1 at the position corresponding to the feeding mechanism 5.

[0024] Specifically, the stabilizing receiving assembly 8 includes an overlap plate 81, a flexible bellows pipe 84, an external flange 85, and extension members 86. The overlap plate 81 is located below the feeding mechanism 5. The flexible bellows pipe 84 is fixedly connected to one end of the overlap plate 81 closest to the feeding mechanism 5. External flanges 85 are fixedly connected to the ends of both the feeding mechanism 5 and the flexible bellows pipe 84 that are close to each other. Extension members 86 are located at both ends of the upper part of the overlap plate 81.

[0025] By adopting the above technical solution, the workbench 4 is moved and overlapped onto the cold chamber die casting machine, and the feeding mechanism 5 is aligned with the injection chamber on the cold chamber die casting machine. Then, the overlapping plate 81 is moved towards the injection chamber. The movement of the overlapping plate 81 causes the elastic bellows 84 to stretch, and the extension piece 86 is used to fix the overlapping plate 81 to the side wall of the injection chamber to ensure the stability of the placement of the elastic bellows 84, thereby ensuring the feeding stability of the injection chamber.

[0026] Specifically, the extension 86 includes a slide rail 861, a slide rod 862, an elastic pad 863, a clamping screw 864, and a clamping frame 865. The slide rail 861 is fixedly connected to both ends of the upper part of the overlapping plate 81. The slide rod 862 is slidably connected inside the slide rail 861. One end of the slide rod 862 is fixedly connected to the clamping frame 865. Clamping screws 864 are threaded onto both sides of the clamping frame 865. Elastic pads 863 are fixedly connected to the ends of the two clamping screws 864 that are close to each other.

[0027] By adopting the above technical solution, the slide rod 862 moves along the slide rail 861, and the movement of the slide rod 862 drives the clamping frame 865 to move. When the clamping frame 865 moves and fits against the two side walls of the injection chamber, the clamping screw 864 is rotated, causing it to rotate and move along the clamping frame 865. The rotation and movement of the clamping screw 864 drives the elastic pad 863 to rotate and move. When the elastic pad 863 moves and fits against the side wall of the injection chamber, the rotation of the clamping screw 864 is stopped, ensuring the stability of the overlapping plate 81.

[0028] Specifically, the stabilizing receiving assembly 8 also includes a limiting frame 82, an L-shaped rod 83, a connecting spring 87, and a support rod 88. L-shaped rods 83 are fixedly connected to the side walls of the workbench 4 on both sides of the overlapping plate 81. Support rods 88 are slidably connected inside the L-shaped rods 83. A connecting spring 87 is fixedly connected between the L-shaped rods 83 and the support rods 88. A limiting frame 82 is fixedly connected to the side walls of the overlapping plate 81 at positions corresponding to the L-shaped rods 83.

[0029] By adopting the above technical solution, when the overlapping plate 81 is not needed, the support rod 88 is moved into the L-shaped rod 83. The support rod 88 moves and compresses the connecting spring 87. Then the overlapping plate 81 is moved towards the worktable 4. Then the support rod 88 is released, the connecting spring 87 loses its external force and returns to its original shape, driving the support rod 88 to move and insert into the limiting frame 82. The support rod 88 and the limiting frame 82 can be used to limit and fix the overlapping plate 81, ensuring the stability of the overlapping plate 81.

[0030] In this embodiment, the workbench 4 is moved and placed onto the cold chamber die-casting machine, and the feeding mechanism 5 is aligned with the injection chamber on the cold chamber die-casting machine. The support rod 88 is moved into the L-shaped rod 83, and the moving support rod 88 compresses the connecting spring 87. After the support rod 88 moves away from the limiting frame 82, the overlapping plate 81 is moved towards the injection chamber. The moving overlapping plate 81 causes the elastic bellows 84 to stretch. Then, the slide rod 862 is moved along the slide rail 861, and the moving slide rod 862 causes the clamping frame 865 to move. After the clamping frame 865 moves and fits against the two side walls of the injection chamber, the tightening screw 864 is rotated to make it... The clamping frame 865 rotates and moves, and the tightening screw 864 rotates and moves, causing the elastic pad 863 to rotate and move. When the elastic pad 863 moves and fits against the side wall of the injection chamber, the tightening screw 864 stops rotating to ensure the stability of the placement of the elastic bellows 84, thereby ensuring the stability of the feeding of the injection chamber. Then, the tilting mechanism 2 drives the rotating mechanism 7 to rotate, and the rotating mechanism 7 drives the storage box 6 to rotate and tilt, so that the material inside the storage box 6 enters the feeding mechanism 5, and then is injected into the injection chamber of the cold chamber die casting machine through the elastic bellows 84, completing the feeding operation of the cold chamber die casting machine.

[0031] Example 2

[0032] The difference between this embodiment and Embodiment 1 is that the unblocking component 3 includes a return spring 31, a moving groove 32, a drive plate 33, an unblocking rod 34, a motor bracket 35, a drive motor 36, and an eccentric wheel 37. The mounting frame 1 has a moving groove 32 on the side near the feeding mechanism 5. The drive plate 33 is slidably connected inside the moving groove 32. A return spring 31 is fixedly connected between the moving groove 32 and the drive plate 33. A motor bracket 35 is fixedly connected to the side wall of the mounting frame 1. A drive motor 36 is fixedly connected to the side wall of the motor bracket 35. An eccentric wheel 37 is fixedly connected to the output end of the drive motor 36. The unblocking rod 34 is fixedly connected to one lower end of the drive plate 33.

[0033] Specifically, guide sliders are fixedly connected to both ends of the drive plate 33, and guide grooves are provided on the inner side wall of the moving groove 32 at the positions corresponding to the guide sliders.

[0034] By adopting the above technical solution, the drive plate 33 moves and drives the guide slider to move inside the guide groove. Under the sliding cooperation of the guide slider and the guide groove, the movement of the drive plate 33 can be guided, thereby improving the stability of the movement of the drive plate 33.

[0035] In this embodiment, after the material inside the storage bin 6 is injected into the feeding mechanism 5, the drive motor 36 on the motor bracket 35 is started. The drive motor 36 rotates, causing the eccentric wheel 37 to rotate. The rotation of the eccentric wheel 37 causes the drive plate 33 to move along the moving groove 32. The movement of the drive plate 33 causes the unblocking rod 34 and the return spring 31 to stretch. With the cooperation of the eccentric wheel 37 and the return spring 31, the unblocking rod 34 can move up and down reciprocatingly. During the up and down reciprocating motion of the unblocking rod 34, the material inside the feeding mechanism 5 can be unblocked, avoiding blockage of the feeding mechanism 5 and affecting the feeding operation of the cold chamber die casting machine.

[0036] In this utility model, the drive motor 36 is a previously disclosed technology, and the selected model is R17-167.

[0037] The structure and principle of the tilting mechanism 2, composed of a servo motor, a guide rod, a lead screw, a vertical plate, a moving plate, a drum, gears, a rack, and a guide rope, have been disclosed in a cold chamber die-casting machine feeding mechanism disclosed in Chinese Patent Application No. 202122827464.8. Its working principle is as follows: the servo motor is installed on the left end of the mounting frame 1, and an opening is provided at the top of the mounting frame 1. The guide rod is fixedly installed in the opening. The right end of the lead screw is rotatably connected to the right end of the opening via a bearing. The left end of the lead screw extends to the left side of the mounting frame 1 and connects to the output end of the servo motor. The moving plate is slidably connected to the guide rod and threadedly connected to the vertical plate. A guide rope opening is provided on the moving plate between the guide rod and the lead screw. The bottom ends of both sets of vertical plates are connected to the top ends of the moving plate. The rotating shaft is rotatably installed on both sets of vertical plates via bearings. Between the vertical plates, the drum is mounted on the rotating shaft. The front end of the rotating shaft extends to the front side of the vertical plate and connects to the rear end of the gear. The rack is mounted on the top of the mounting bracket 1. The gear meshes with the rack. One end of the guide rope is wound around the drum, and the other end of the guide rope passes through the guide rope opening and connects to the top of the rotating mechanism 7. In use, the servo motor is started to rotate forward, which causes the lead screw to drive the moving plate to move to the right with the cooperation of the guide screw. As the moving plate moves to the right, it drives the two sets of vertical plates, the drum, and the gear to move to the right. As the gear moves to the right, it rotates clockwise with the cooperation of the rack, which drives the drum to rotate clockwise through the rotating shaft. This causes the drum to wind up the guide rope, which in turn drives the other end of the guide rope to rotate clockwise. The rotating mechanism 7 then causes the storage box 6 to tilt.

[0038] The structure and principle of the feeding mechanism 5, which consists of a funnel, a conveying pipe, and an electric valve, in this utility model have been disclosed in a cold chamber die-casting machine feeding mechanism disclosed in Chinese patent application number 202122827464.8. Its working principle is as follows: a conveying pipe is fixedly connected inside the worktable 4 and on one side of the rotating mechanism 7. A funnel is fixedly connected to one end of the conveying pipe, and an electric valve is provided at the other end of the conveying pipe. When in use, after the material inside the storage box 6 is injected into the funnel, the electric valve is opened, and the material inside the funnel is injected into the injection chamber of the cold chamber die-casting machine through the conveying pipe.

[0039] The structure and principle of the rotating mechanism 7, which consists of a vertical plate, a rotating shaft, and an adjusting plate, in this utility model have been disclosed in a cold chamber die-casting machine feeding mechanism disclosed in Chinese patent application number 202122827464.8. Its working principle is as follows: the bottom ends of the two sets of vertical plates are connected to the top of the worktable 4. The rotating shaft is rotatably installed between the two sets of vertical plates through bearings. The adjusting plate is installed on the rotating shaft. In use, the tilting mechanism 2 drives one end of the adjusting plate to rotate under the action of the rotating shaft, so that the adjusting plate tilts. The tilting of the adjusting plate causes the storage box 6 to tilt and discharge material.

[0040] The working principle and usage process of this utility model are as follows: The workbench 4 is moved and connected to the cold chamber die-casting machine, and the feeding mechanism 5 is aligned with the injection chamber of the cold chamber die-casting machine. The support rod 88 moves inward towards the L-shaped rod 83, pressing the connecting spring 87. After the support rod 88 moves away from the limiting frame 82, the overlapping plate 81 moves towards the injection chamber. The movement of the overlapping plate 81 causes the elastic bellows 84 to stretch. Then, the slide rod 862 moves along the slide rail 861, causing the clamping frame 865 to move. When the clamping frame 865 moves and adheres to the two side walls of the injection chamber, the tightening screw 864 is rotated, causing it to rotate and move along the clamping frame 865. The rotation of the tightening screw 864 causes the elastic pad 863 to rotate and move. When the elastic pad 863 moves and adheres to the side wall of the injection chamber, the rotation of the tightening screw 864 is stopped, ensuring the stable placement of the elastic bellows 84. This ensures the stability of the material feeding in the injection chamber. Then, the tilting mechanism 2 drives the rotating mechanism 7 to rotate, which in turn drives the storage box 6 to rotate and tilt, allowing the material inside the storage box 6 to enter the feeding mechanism 5. Next, the drive motor 36 on the motor bracket 35 is started. The drive motor 36 rotates, which drives the eccentric wheel 37 to rotate. The eccentric wheel 37 rotates, which drives the drive plate 33 to move along the moving groove 32. The movement of the drive plate 33 causes the unblocking rod 34 and the return spring 31 to stretch. With the cooperation of the eccentric wheel 37 and the return spring 31, the unblocking rod 34 can move up and down. During the up and down reciprocating motion of the unblocking rod 34, the material inside the feeding mechanism 5 can be unblocked to prevent the feeding mechanism 5 from being blocked and affecting the feeding operation of the cold chamber die casting machine. Then, the material is injected into the injection chamber of the cold chamber die casting machine through the elastic bellows 84, completing the feeding operation of the cold chamber die casting machine.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
