[0034] An embodiment of the present application provides a precious metal extrusion device, comprising:

[0035] A support frame, wherein a discharge pipe and a power assembly are provided on the support frame, and the length direction of the discharge pipe is recorded as a first direction;

[0036] A material holding mold, the material holding mold is rotatably connected to the support frame, a material holding groove is provided on the material holding mold, the length direction of the material holding groove is recorded as a second direction, and both ends of the material holding groove in the second direction pass through the material holding mold;

[0037] An injection mold, wherein the injection mold is transmission-connected to the power assembly, and the receiving mold is located on a transmission path of the injection mold, and when the injection mold moves to fit the receiving mold, the precious metal is injected into the receiving groove through the injection mold;

[0038] Extrusion dies, both of which are in transmission connection with the power assembly, the power assembly drives the two extrusion dies to move toward each other, and the transmission direction of the extrusion dies is recorded as the third direction;

[0039] When the material holding trough rotates along with the material holding die to the point where the second direction is parallel to the third direction, the power assembly pushes the two extrusion dies into the material holding trough to extrude the precious metal;

[0040] When the trough rotates with the die to a second direction parallel to the first direction, the discharge pipe connects to the trough, and the power assembly pushes the precious metal in the trough out of the discharge pipe. The aforementioned precious metal extrusion device extrudes the precious metal through the interaction between the injection mold, the extrusion mold, and the trough. When the trough rotates to be parallel to the discharge pipe, the power assembly pushes the precious metal raw material in the trough out of the discharge pipe. This design allows the extruded precious metal workpiece to be automatically discharged from the device without manual intervention.

[0041] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0042] See also Figure 1-Figure 5 An embodiment of the present application provides a precious metal extrusion device 100, comprising a support frame 1, a material holding die 2, an injection mold 3, and an extrusion mold 4. The support frame 1 is provided with a discharge pipe 11 and a power assembly 12. The length direction of the discharge pipe 11 is recorded as the first direction. The material holding die 2 is rotatably connected to the support frame 1. The material holding die 2 is provided with a material holding trough 21. The length direction of the material holding trough 21 is recorded as the second direction. Both ends of the material holding trough 21 in the second direction pass through the material holding die 2. The injection mold 3 is transmission-connected to the power assembly 12, and the material holding die 2 is located on the transmission path of the injection mold 3. When the injection mold 3 moves to fit the material holding die 2, the precious metal is injected into the material holding trough 21 through the injection mold 3. The two extrusion molds 4 are both transmission-connected to the power assembly 12. The power assembly 12 pushes the two extrusion molds 4 to move toward each other. The transmission direction of the extrusion mold 4 is recorded as the third direction. When the material holding trough 21 rotates along with the material holding die 2 to the second direction parallel to the third direction, the power assembly 12 pushes the two extrusion dies 4 into the material holding trough 21 to extrude the precious metal. When the material holding trough 21 rotates along with the material holding die 2 to the second direction parallel to the first direction, the discharge pipe 11 communicates with the material holding trough 21, and the power assembly 12 pushes the precious metal in the material holding trough 21 to be discharged from the discharge pipe 11.

[0043] Specifically, the support frame 1 provides the basic structural support for the device, while the discharge pipe 11 is responsible for discharging the precious metal after extrusion. The stability of the support frame 1 ensures the smooth operation of the device, while the discharge pipe 11 ensures that the precious metal after extrusion can be discharged smoothly, avoiding blockage or accumulation. A material storage tank 21 is provided on the material storage mold 2 for accommodating the precious metal to be processed. Through the rotation connection with the support frame 1, the material storage mold 2 can be rotated when needed. This is mainly to connect with the discharge pipe 11 and face the extrusion mold 4 respectively, so as to switch between the two states during processing, and at the same time make the precious metal evenly distributed during the processing. This ensures the uniformity and stability of the precious metal during the extrusion process, thereby improving processing efficiency and product quality. The injection mold 3 is connected to the power assembly 12 in a transmission manner and is responsible for injecting the precious metal into the material storage tank 21. Its fit with the material storage mold 2 enables the injection process to be carried out accurately, thereby ensuring the accurate injection and processing of the precious metal. The two extrusion dies 4 are connected to the power assembly 12, which drives the two extrusion dies 4 to move toward each other to extrude the precious metal. This ensures that the force during the extrusion process is evenly distributed, thereby ensuring the uniformity and stability of the product.

[0044] First, the precious metal is injected into the trough 21 through the injection mold 3 to form an injection area. Then, the power assembly 12 pushes the extrusion mold 4 toward each other, extruding the precious metal within the trough 21. Finally, when the trough 2 rotates to connect with the discharge pipe 11, the power assembly 12 pushes the precious metal in the trough 21 to be discharged through the discharge pipe 11.

[0045] In a specific example, the power assembly 12 includes a first hydraulic cylinder 121 , and a transmission direction of the first hydraulic cylinder 121 is parallel to the first direction;

[0046] When the material holding trough 21 rotates along with the material holding mold 2 to the point where the second direction is parallel to the first direction, the first hydraulic cylinder 121 pushes the precious metal into the discharge pipe 11 for discharge.

[0047] Specifically, the first hydraulic cylinder 121 is part of the power assembly 12 and is used to provide power to control the discharge of the precious metal. Its transmission direction is parallel to the first direction, meaning that the movement of the first hydraulic cylinder 121 aligns with the length of the discharge pipe 11, effectively controlling the flow of the precious metal within the discharge pipe 11. When the trough 21 rotates with the die 2 to a second direction parallel to the first, the precious metal has been extruded and the trough 21 has reached a position where it can communicate with the discharge pipe 11. At this point, the first hydraulic cylinder 121 is activated, pushing the precious metal into the discharge pipe 11 and out of the device. The movement of the first hydraulic cylinder 121 is parallel to the length of the discharge pipe 11, ensuring smooth flow and discharge of the precious metal without obstruction or blockage. When the trough 21 rotates to the appropriate position, the control system activates the first hydraulic cylinder 121. The first hydraulic cylinder 121 pushes forward, pushing the precious metal from the trough 21 into the discharge pipe 11. Since the transmission direction of the first hydraulic cylinder 121 is parallel to the discharge pipe 11, the process of pushing the precious metal can be carried out efficiently and smoothly, thereby ensuring the timely discharge of the precious metal. The control system is generally a computer.

[0048] In a specific example, a push plate 1211 is provided on the first hydraulic cylinder 121 , and the push plate 1211 is transmission-connected to the first hydraulic cylinder 121 , so that the first hydraulic cylinder 121 pushes the precious metal in the material trough 21 through the push plate 1211 .

[0049] Specifically, the pusher plate 1211 is a device or component typically used to apply force or push an object. In this scenario, the function of the pusher plate 1211 is to push the precious metal in the trough 21 toward the discharge pipe 11, thereby discharging the precious metal. The first hydraulic cylinder 121 and the pusher plate 1211 are connected by a transmission connection, which means that the movement of the first hydraulic cylinder 121 can be directly transmitted to the pusher plate 1211, thereby achieving control of the pusher plate 1211. The transmission connection is usually achieved through some mechanical structure (such as a connecting rod, gears, or a connecting rope), ensuring that the movement of the first hydraulic cylinder 121 can be accurately converted into the movement of the pusher plate 1211. When the first hydraulic cylinder 121 is activated, it applies pressure and pushes the pusher plate 1211. The movement of the pusher plate 1211 directly acts on the precious metal in the trough 21, pushing it toward the discharge pipe 11. In this way, through the coordinated action of the first hydraulic cylinder 121 and the pusher plate 1211, the precious metal can be effectively discharged from the device, ensuring the smooth progress of the processing process. When the device needs to discharge precious metal, the control system activates the first hydraulic cylinder 121. This applies pressure, transmitting this force to the drive-connected pusher plate 1211. This pressure forces the pusher plate 1211 toward the discharge pipe 11, pushing the precious metal in the trough 21 along with it. The precious metal is smoothly pushed toward the discharge pipe 11, completing the discharge process.

[0050] In a specific example, an injection hole 31 is provided on the injection mold 3. When the injection mold 3 moves to fit with the containing mold 2, one end of the injection hole 31 is connected to the containing groove 21 and the other end is connected to the outside world. A valve 32 is provided at the end of the injection hole 31 connected to the outside world.

[0051] Specifically, the injection mold 3 is provided with an injection hole 31, which is a through hole or opening, usually located at a specific position of the injection mold 3. The function of the injection hole 31 is to allow precious metal to be injected from the outside into the material tank 21 for use in the extrusion process. When the injection mold 3 moves to fit with the material mold 2, a close contact surface is formed between them. This fit ensures the accuracy and stability of the injection process, allowing the precious metal to be accurately injected into the material tank 21, avoiding waste or uneven injection. One end of the injection hole 31 is connected to the material tank 21, which means that when the injection mold 3 is fitted with the material mold 2, a channel is formed between the injection hole 31 and the material tank 21. This channel allows the precious metal to enter the material tank 21 from the injection hole 31 in preparation for the extrusion process. The other end of the injection hole 31 is connected to the outside world, usually connected to an external feeding system through a pipe or other connection method. The purpose of this design is to facilitate the supply of precious metal from the outside to the injection mold 3 in preparation for processing. In order to control the injection process of the precious metal, a valve 32 is usually provided at the end of the injection hole 31 that is connected to the outside world. This valve 32 can control the flow of the precious metal, ensuring the accuracy and controllability of the injection process. When the device needs to be injected, the control system will open the injection valve 32, allowing the precious metal to flow from the outside into the injection hole 31. The precious metal enters the holding tank 21 through the injection hole 31, ready for extrusion. The design and position of the injection hole 31 ensure that the precious metal can be accurately injected into the holding tank 21, and the setting of the valve 32 ensures the control and regulation of the injection process.

[0052] In a specific example, the support frame 1 is provided with a first gear 14 that is transmission-connected to the power assembly 12 and a second gear 15 that is transmission-connected to the first gear 14. The material-holding mold 2 is provided on the second gear 15, and the material-holding mold 2 rotates as the second gear 15 rotates.

[0053] Specifically, the first gear 14 is located on the support frame 1 and is transmission-connected to the power assembly 12, which means that the power of the power assembly 12 can be transmitted to the first gear 14. The transmission connection is usually achieved through gears, belts, chains, etc. to ensure that the power can be effectively transmitted to the gear system. The transmission connection between the first gear 14 and the second gear 15: The first gear 14 is transmission-connected to the second gear 15, which means that the rotation of the first gear 14 will drive the second gear 15 to rotate together. This transmission connection ensures that the movement of the second gear 15 can be synchronized with the power transmitted from the power assembly 12, ensuring the coordinated operation of the entire gear system. The material holding mold 2 is mounted on the second gear 15, which means that the material holding mold 2 and the second gear 15 are connected by some kind of mechanical connection. This connection ensures that the material holding mold 2 can perform corresponding rotational movement as the second gear 15 rotates. When the material holding assembly rotates with the second gear 15, the orientation of the second direction also changes, thereby achieving parallelism with the first direction or the second direction.

[0054] In a specific embodiment, the support frame 1 is provided with a second hydraulic cylinder 122, and the second hydraulic cylinder 122 is provided with a push rod 1221. The second gear 15 is provided with a stop hole 151. The second hydraulic cylinder 122 pushes the push rod 1221 to enter or leave the stop hole 151. When the push rod 1221 is located in the stop hole 151, the second gear 15 stops rotating.

[0055] The push rod 1221 leaves the stop hole 151 and the second gear 15 continues to rotate.

[0056] Specifically, the second hydraulic cylinder 122 is a hydraulic device mounted on the support frame 1, used to control the movement of the push rod 1221. The push rod 1221 is a rod-shaped object connected to the second hydraulic cylinder 122. Its function is to enter or exit the stop hole 151 on the second gear 15 when necessary, thereby controlling the rotation of the second gear 15. The second gear 15 is provided with one or more stop holes 151, which are used to allow the push rod 1221 to enter and prevent the rotation of the second gear 15. When it is necessary to stop the rotation of the second gear 15, the second hydraulic cylinder 122 controls the movement of the push rod 1221 to move it into the stop hole 151. After entering the stop hole 151, the push rod 1221 comes into physical contact with the second gear 15, preventing the second gear 15 from further rotation. When it is no longer necessary to prevent the rotation of the second gear 15, the second hydraulic cylinder 122 controls the movement of the push rod 1221 to move it out of the stop hole 151. After the push rod 1221 leaves the stop hole 151, the second gear 15 can continue to rotate freely. During operation of the device, the rotation state of the second gear 15 is controlled as needed, and the control system controls the movement of the push rod 1221 through the second hydraulic cylinder 122. When it is necessary to stop the rotation of the second gear 15, the control system applies pressure to the second hydraulic cylinder 122, causing the push rod 1221 to enter the stop hole 151, thereby preventing the rotation of the second gear 15. When it is no longer necessary to stop the rotation of the second gear 15, the control system releases the pressure, causing the push rod 1221 to leave the stop hole 151, and the second gear 15 can rotate freely.

[0057] In a specific example, a sliding rod 13 is provided on the support frame 1 , the length direction of the sliding rod 13 is parallel to the first direction, and the pusher plate 1211 is slidably connected to the sliding rod 13 .

[0058] Specifically, a sliding rod 13 is provided on the support frame 1. The sliding rod 13 is typically a linear object with its length parallel to the first direction. The function of the sliding rod 13 is to provide support and guidance to ensure that the direction and method of movement of the push plate 1211 meet the design requirements. The push plate 1211 is connected to the sliding rod 13 by sliding, which means that the push plate 1211 can move along the length of the sliding rod 13. This connection method generally uses a mechanical connection method such as a sliding pair or bearing to ensure smooth and stable movement of the push plate 1211 on the sliding rod 13. The length of the sliding rod 13 is parallel to the first direction, which means that the sliding rod 13 extends along the first direction in the device. This design is generally intended to enable the push plate 1211 to move along a specific direction in the device to perform the function of pushing the material. The push plate 1211 is typically located near the material storage tank 21 or the injection mold 3. Its function is to push the precious metal or other material into the processing area for the next processing operation. By moving the push plate 1211 , the position and flow direction of the precious metal in the device can be controlled, thereby achieving precise control and operation during the processing.

[0059] In a specific example, the power assembly 12 includes a first motor 124 , and the first motor 124 is in transmission connection with the first gear 14 .

[0060] Specifically, the power assembly 12 is the key component responsible for providing power within the device. It typically consists of a motor, hydraulic cylinder, and other drive devices, driving the various moving parts within the device. The first motor 124 is a crucial component within the power assembly 12 and is typically one of the primary sources of mechanical power within the device. The motor can be an AC motor, a DC motor, or other types, depending on the specific application and design requirements. The first gear 14 is a gear transmission component within the device, receiving power from the first motor 124 and transmitting it to other components. The first gear 14 is typically connected to the first motor 124 through a mechanical connection, such as by a shaft, coupling, or other means fixed to the motor's output shaft. The first motor 124 and the first gear 14 are connected via a transmission connection, meaning that the rotation of the first motor 124 can be transmitted to other components via the first gear 14. This transmission connection can be achieved through a direct mechanical structure or through a belt, chain, or other means, depending on the design requirements and the device's operating conditions. When the first motor 124 is started, it generates mechanical rotation, which is transmitted to the first gear 14 via the transmission connection. After receiving power from the motor, the first gear 14 transmits it to other components in the device, thereby driving the device to complete a specific movement or work task.

[0061] In a specific example, the power assembly 12 includes a first oil cylinder 125 , which is transmission-connected to the injection mold 3 , and the first oil cylinder 125 pushes the injection mold 3 toward or away from the holding mold 2 .

[0062] Specifically, the first oil cylinder 125 is a hydraulic device in the device, which is usually composed of an oil cylinder body, a piston and a hydraulic system. Its function is to realize the push-pull movement of the piston through hydraulic pressure, thereby driving the components connected to it to perform corresponding actions. The first oil cylinder 125 is connected to the injection mold 3 through a transmission connection, which means that the movement of the first oil cylinder 125 can be transmitted to the injection mold 3. The transmission connection is usually achieved through a mechanical structure between the oil cylinder piston and the injection mold 3, for example, through a connection method such as a pin, a connecting rod, etc. The main function of the first oil cylinder 125 is to control the position of the injection mold 3 so that it can move closer to or further away from the holding mold 2 to control the injection process of the precious metal. When the first oil cylinder 125 pushes the injection mold 3 closer to the holding mold 2, the precious metal can be injected into the holding tank 21 through the injection hole 31, thereby performing subsequent extrusion processing. When the first oil cylinder 125 moves the injection mold 3 away from the holding mold 2, the precious metal injection process is stopped so that the next operation or preparation work can be carried out. During operation, according to the processing technology and control system instructions, the first oil cylinder 125 controls the inflow and outflow of oil through the hydraulic system, thereby driving the movement of the injection mold 3. When precious metal injection is required, the first oil cylinder 125 pushes the injection mold 3 toward the holding mold 2, allowing the precious metal to be injected into the holding tank 21 through the injection hole 31. When the injection process is completed or it is necessary to stop injection, the first oil cylinder 125 moves the injection mold 3 away from the holding mold 2, stopping the precious metal injection process.

[0063] In a specific example, the power assembly 12 includes a third hydraulic cylinder 123 , which is in transmission connection with the extrusion die 4 , and the third hydraulic cylinder 123 pushes the extrusion die 4 to move along the third direction.

[0064] Specifically, the third hydraulic cylinder 123 is a hydraulic device in the device, similar to the first oil cylinder 125, and is used to control the push-pull movement of the piston through liquid pressure. It is connected to the hydraulic system and realizes the movement control of the piston by adjusting the pressure and flow in the hydraulic system. The third hydraulic cylinder 123 is connected to the extrusion die 4 through a transmission connection, which means that the movement of the third hydraulic cylinder 123 can be transmitted to the extrusion die 4. The transmission connection is usually realized by a mechanical structure between the piston of the hydraulic cylinder and the extrusion die 4, such as through a pin, a connecting rod and other connection methods. The main function of the third hydraulic cylinder 123 is to control the movement of the extrusion die 4 along the third direction, thereby realizing the extrusion processing of the precious metal. When the third hydraulic cylinder 123 pushes the extrusion die 4 to move along the third direction, the extrusion die 4 will apply pressure to the precious metal, thereby realizing the extrusion processing thereof.

[0065] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
