Description

Technical Field

[0001] The utility model relates to the technical field of die-casting, in particular to an automatic feeding mechanism for a die-casting machine. Background Technique

[0002] A die-casting machine is a machine used for pressure casting, including two types: a hot chamber and a cold chamber, and later it is divided into two types: vertical and horizontal. Under pressure, the die-casting machine hydraulically injects molten metal into the mold for cooling and forming. After the mold is opened, solid metal castings can be obtained. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and household appliances, die-casting technology has developed extremely rapidly.

[0003] As an important device in modern manufacturing, there are many defects in the feeding mechanisms of die-casting machines on the current market, which affect the smoothness of production and cost control. For example, the utility model with the patent number CN216938369U designs an inclined feeding mechanism, aiming to inject materials into the mold in an inclined manner. However, in actual applications, this design brings a series of problems. First, the design of the inclined hopper makes it difficult to accurately align the injection port of the mold when injecting materials. This not only increases the complexity of operation but also often leads to misplacement of materials, resulting in waste of raw materials. Second, since the feeding mechanism cannot accurately control the quantity of injected raw materials, it often leads to unstable product quality. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic feeding mechanism for a die-casting machine to solve the problems raised in the above background technique.

The end of the threaded rod away from the motor is inserted into a sleeve, and the threaded rod and the sleeve are connected by threads. Several guide rails are fixed on the outside of the sleeve, and a plug is provided at the end of the sleeve away from the guide rails. The end of the plug away from the guide rails is attached to the pouring port, which is opened at the bottom of the hopper. Several connecting plates are fixed on the side of the hopper, and a reinforcing plate is fixed at the end of each connecting plate away from the hopper. The ends of the reinforcing plate and the connecting plate are both fixed at the bottom of the baffle. The motor rotates in cooperation with the threaded rod to lift the sleeve, thereby lifting the plug away from the pouring port, so as to release the molten metal stored in the hopper.

[0006] Preferably, a telescopic structure body is fixed on one side of the robotic arm. The end of the telescopic structure body is connected with several arc-shaped cover bodies. The telescopic structure body is used to control the opening and closing of the arc-shaped cover bodies, and the arc-shaped cover bodies are used to prevent the molten metal from dripping.

[0007] Preferably, crescent grooves are provided on both sides of several of the connecting plates to reduce the obstruction of the connecting plates to the liquid metal when the hopper is loading liquid metal.

[0008] Preferably, the bottom of the hopper is semi-circular to facilitate the convergence of liquid metal to the pouring port.

[0009] Preferably, several sliding rails are provided inside the robotic arm at the position of the guide rail, and each sliding rail is provided with a guide rail, and the sliding rail is used to limit the moving direction of the guide rail.

[0010] Preferably, a fillet is provided at the connection between the hopper and the connecting plate, and the fillet prevents the metal liquid from accumulating at the connection between the hopper and the connecting plate, causing waste.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: an automatic feeding mechanism for a die-casting machine, including a robotic arm 2. A motor 3 is provided in the middle of the robotic arm 2. A connecting rod 6 fixed to the robotic arm 2 is provided on the side of the motor 3. There are several connecting rods 6. The output end of the motor 3 is fixed with a threaded rod 7. One end of the threaded rod 7 away from the motor 3 is inserted into a sleeve 8, and the threaded rod 7 is threadedly connected with the sleeve 8. A plurality of guide rails 11 are fixed on the outer side of the sleeve 8. A plug 13 is provided at one end of the sleeve 8 away from the guide rails 11. One end of the plug 13 away from the guide rails 11 is attached to the pouring port 16. The pouring port 16 is opened at the bottom of the hopper 9. A plurality of connecting plates 10 are fixed on the side of the hopper 9. One end of each connecting plate 10 away from the hopper 9 is fixed with a reinforcing plate 14. The ends of the reinforcing plate 14 and the connecting plate 10 are both fixed to the bottom of the baffle 4. The motor 3 rotates to lift the sleeve 8 in cooperation with the threaded rod 7, thereby lifting the plug 13 to make the plug 13 away from the pouring port 16, so as to release the molten metal stored in the hopper 9.

[0023] Furthermore, a telescopic structure body 1 is fixed on one side of the robotic arm 2. A plurality of arc-shaped cover bodies 5 are connected to the end of the telescopic structure body 1. The telescopic structure body 1 is used to control the opening and closing of the arc-shaped cover bodies 5, and the arc-shaped cover bodies 5 are used to prevent the molten metal from dripping.

[0024] Furthermore, crescent grooves 12 are provided on both sides of several of the connecting plates 10 to reduce the obstruction of the connecting plates 10 to the liquid metal when the hopper 9 is loading liquid metal.

[0025] Furthermore, the bottom of the hopper 9 is semi-circular, facilitating the convergence of liquid metal to the pouring port 16.

[0026] Furthermore, several sliding rails 15 are provided inside the robotic arm 2 at the position of the guide rail 11, and each sliding rail 15 is clamped with the guide rail 11. The sliding rails 15 are used to limit the moving direction of the guide rail 11.

[0027] Furthermore, a fillet 101 is provided at the connection between the hopper 9 and the connecting plate 10, and the fillet 101 prevents the accumulation of molten metal at the connection between the hopper 9 and the connecting plate 10, causing waste.

[0028] Working principle: When using the device, first control the motor 3 to rotate to drive the threaded rod 7 to rotate. Since the sleeve 8 is connected to the plug 13, and several guide rails 11 are fixed to the side of the sleeve 8, when the threaded rod 7 rotates, due to the mutual cooperation of the guide rail 11 and the sliding rail 15, the sleeve 8 will not rotate. Therefore, the sleeve 8 will move up and down along the direction of the guide rail 11. By rotating the motor 3, the sleeve 8 and the plug 13 are pushed down, so that the plug 13 is completely fitted with the pouring port 16, and then the liquid metal can be loaded into the hopper 9.

[0029] Then control the telescopic structure body 1 to close the arc-shaped cover body 5, and then move the hopper 9 to directly above the mold by controlling the robotic arm 2. Subsequently, open the arc-shaped cover body 5, control the motor 3 to rotate to drive the threaded rod 7 to rotate, and the threaded rod 7 lifts the sleeve 8 to drive the plug 13 away from the pouring port 16, thereby releasing the liquid metal. By controlling the distance between the plug 13 and the pouring port 16, the flow rate of the liquid metal can be controlled, so as to accurately control the pouring amount of the liquid metal.

[0030] It should be noted that: The entire device is controlled by a total control device. Since the devices matched with the control device are common devices and belong to the existing mature technologies, the electrical connection relationship and the specific circuit structure are not described in detail herein.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
