This invention can, on the one hand, clean the dust on the surface of the lower mold, reducing the amount of dust adsorbed, and on the other hand, improve the precision and surface quality of subsequent embossing.

[0004] The inventors believe that the above-mentioned precious metal embossing mold can perform embossing operations during precious metal processing. Therefore, the precious metal embossing mold is an embossing device for precious metal processing. However, when the precious metal embossing mold is used, it can only process a single precious metal material at a time. As a result, after the precious metal material is processed, the embossed precious metal material needs to be removed before processing can continue. Continuous processing is not possible, which is time-consuming and affects the overall processing efficiency of precious metals.

[0005] Therefore, this utility model provides an embossing device for precious metal processing to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an embossing device for precious metal processing, which aims to solve the problem that the existing precious metal embossing mold can only process a single precious metal material at a time. As a result, after the precious metal material is processed, the embossed precious metal material needs to be removed before the next processing can be carried out, which makes continuous processing impossible. This operation is time-consuming and affects the overall processing efficiency of precious metals.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an embossing device for precious metal processing, comprising a base, a support frame fixedly connected to the middle of the rear surface of the base, a hydraulic rod connected to the top surface of the support frame, the movable end of the hydraulic rod passing through the support frame and connected to the top surface of the upper mold, a lower mold provided below the upper mold, four sets of the lower molds arranged in a circular array on the top surface of the rotating platform, a rotating shaft fixedly connected to the middle of the bottom surface of the rotating platform, one end of the rotating shaft passing through a bearing embedded in the top surface of the base, and the other end of the rotating shaft extending into the base and fixedly connected to the output end of a motor, four sets of slots arranged in a circular array on the outer surface of the rotating platform, one end of a limit rod slidingly inserted into the slot, and support legs connected to the bottom surface at the four corners of the base.

[0008] In a preferred embodiment of the embossing device for precious metal processing according to this utility model, a rotating ring is connected to the bottom surface of the rotating table, one end of the rotating ring extends into a rotating groove opened on the top surface of the base, and the rotating ring is slidably connected to the base through the rotating groove.

[0009] As a preferred embodiment of the embossing device for precious metal processing according to this utility model, the other end of the limiting rod is connected to a connecting plate, the other end of the connecting plate passes through a sliding groove symmetrically opened on the top surface of the base, and the bottom surface of the base is symmetrically provided with a first electric push rod, the movable groove of the first electric push rod being connected to one side surface of the bottom end of the connecting plate.

[0010] In a preferred embodiment of the embossing device for precious metal processing according to this utility model, a movable groove is provided on the bottom surface of the support leg, a second electric push rod is connected to the top surface of the inner side of the movable groove, the movable end of the second electric push rod is connected to the top surface of the movable block, a pulley is connected to the bottom surface of the movable block, and the movable block is slidably connected to the support leg through the movable groove.

[0011] As a preferred embodiment of the embossing device for precious metal processing according to this utility model, ventilation holes are provided on both sides of the top end of the support leg, and the position of the ventilation holes is connected to the position of the moving groove.

[0012] In a preferred embodiment of the embossing device for precious metal processing according to this utility model, the motor, the first electric push rod, and the second electric push rod are electrically connected to an external power source via a control switch.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention features four sets of lower molds that match the upper mold on a rotating platform. After the upper mold completes the embossing operation on the precious metal material in the lower mold directly below, the motor can be started, causing the motor output to drive the rotating shaft to rotate. This causes the rotating shaft to rotate the rotating platform 90 degrees, moving another lower mold directly below the upper mold. At this point, the upper mold can perform the embossing operation again, enabling continuous processing. This prevents operators from having to remove the material after each embossing operation before continuing processing, thus saving operating time and improving the overall processing efficiency of precious metal materials.

[0015] This invention activates a second electric push rod, causing the movable end of the second electric push rod to slide the moving block within the moving groove. This allows the pulley at the bottom of the moving block to contact the ground and support the embossing device. At this time, the operator can easily move the embossing device using the pulley, preventing manual handling and thus facilitating the movement of the embossing device. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-4 The present invention provides the following technical solution: an embossing device for precious metal processing, comprising a base 1, a support frame 2 fixedly connected to the middle of the rear surface of the base 1, a hydraulic rod 3 connected to the top surface of the support frame 2, the movable end of the hydraulic rod 3 passing through the support frame 2 and connected to the top surface of the upper mold 4, a lower mold 5 provided below the upper mold 4, four sets of lower molds 5 connected in a circular array on the top surface of the rotating table 6, a rotating shaft 7 fixedly connected to the middle of the bottom surface of the rotating table 6, one end of the rotating shaft 7 passing through a bearing 8 embedded in the top surface of the base 1, and the other end of the rotating shaft 7 extending into the base 1 and fixedly connected to the output end of the motor 9, four sets of slots 12 opened in a circular array on the outer surface of the rotating table 6, one end of a limit rod 13 slidingly inserted into the slot 12, and support legs 17 connected to the bottom surface at the four corners of the base 1.

[0024] Preferably, a rotating ring 10 is connected to the bottom surface of the rotating platform 6, and one end of the rotating ring 10 extends into the rotating groove 11 opened on the top surface of the base 1. The rotating ring 10 and the base 1 are slidably connected through the rotating groove 11.

[0025] In practical use, when the rotating platform 6 rotates, the rotating ring 10 at the bottom of the rotating platform 6 will also slide in the rotating groove 11 on the base 1 to ensure the stability of the rotating platform 6 when it rotates, and at the same time provide stable support for the rotating platform 6.

[0026] Preferably, the other end of the limiting rod 13 is connected to a connecting plate 14, and the other end of the connecting plate 14 passes through a symmetrically opened sliding groove 15 on the top surface of the base 1. The bottom surface of the base 1 is symmetrically provided with a first electric push rod 16, and the movable groove of the first electric push rod 16 is connected to one side surface of the bottom end of the connecting plate 14.

[0027] In practical use, by activating the first electric push rod 16, the movable end of the first electric push rod 16 can drive the connecting plate 14 to slide in the slide groove 15, so that the connecting plate 14 can move with the limiting rod 13, allowing the limiting rod 13 to separate out or insert into the slot 12.

[0028] Preferably, the bottom surface of the support leg 17 is provided with a movable groove 18, the top surface of the inner side of the movable groove 18 is connected to a second electric push rod 19, the movable end of the second electric push rod 19 is connected to the top surface of the movable block 20, the bottom surface of the movable block 20 is connected to a pulley 21, and the movable block 20 is slidably connected to the support leg 17 through the movable groove 18.

[0029] In practical use, by activating the second electric push rod 19, the movable end of the second electric push rod 19 can drive the moving block 20 to move within the moving groove 18 on the support leg 17, so that the moving block 20 can move out or retract into the moving groove 18 with the pulley 21.

[0030] Preferably, ventilation holes 22 are provided on both sides of the top end of the support leg 17, and the position of the ventilation holes 22 is connected to the position of the moving groove 18.

[0031] In practical use, the vent 22 allows the air inside the moving slot 18 to circulate with the outside air, ensuring that the heat generated by the second electric push rod 19 in the moving slot 18 can be dissipated, and the vent 22 is set at an angle.

[0032] Preferably, the motor 9, the first electric push rod 16, and the second electric push rod 19 are electrically connected to an external power source via a control switch.

[0033] In practical use, the motor 9, the first electric push rod 16, and the second electric push rod 19 can be controlled by a control switch. By setting the control switch, the output end of the motor 9 can be rotated 90 degrees each time after the control switch starts the motor 9.

[0034] It should be noted that the size and position of the lower mold 5 match the size and position of the upper mold 4. After each 90-degree rotation of the rotating table 6, the lower mold 5 on the rotating table 6 can be accurately moved to the position directly below the upper mold 4, so that the upper mold 4 can be accurately closed with the lower mold 5 directly below it. At the same time, the size and position of the slot 12 also match the size and position of the limiting rod 13. After each 90-degree rotation of the rotating table 6, the slot 12 will be accurately moved to the position of the limiting rod 13, so that the limiting rod 13 can be inserted into the slot 12.

[0035] Working principle: When using this precious metal embossing device, precious metal materials are placed in all four sets of lower molds 5. Then, the first electric push rod 16 is activated, causing its movable end to slide the connecting plate 14 in the slide groove 15. This allows the limiting rod 13 at the top of the connecting plate 14 to insert into the slot 12 on the rotating table 6, thus fixing the position of the rotating table 6. Next, the hydraulic rod 3 is activated, causing its movable end to move the upper mold 4 downwards, closing it with the lower mold 5 directly below. At this point, the precious metal materials in the lower mold 5 have completed the embossing process. After the embossing operation is completed, the upper mold 4 is separated from the slot 12. The first electric push rod 16 is activated again, causing the connecting plate 14 to drive the limiting rod 13 to separate from the slot 12. At this time, the motor 9 is activated, causing the output end of the motor 9 to drive the rotating shaft 7 to rotate in the bearing 8, so that the rotating shaft 7 can rotate the rotating table 6 90 degrees. At this time, the other lower mold 5 on the rotating table 6 will move to directly below the upper mold 4. Then, the limiting rod 13 is activated again to insert into the slot 12 to limit the rotating table 6, allowing the upper mold 4 to perform the embossing operation on the precious metal material in the other lower mold 5. When the precious metal material in the lower mold 5 completes the embossing operation and moves out from directly below the upper mold 4, the operator can then remove and place the precious metal material in the lower mold 5. This operation allows the embossing device to perform continuous processing, preventing the operator from having to remove the material after each embossing operation, thus saving operating time and improving the overall processing efficiency of precious metal materials. Secondly, when the embossing device needs to be moved, simply activate the second electric push rod 19, causing the movable end of the second electric push rod 19 to drive the moving block 20 to slide within the moving groove 18, thus moving the moving block... The pulley 21 at the bottom of the 20 can move out of the moving groove 18, allowing the pulley 21 to contact the ground and support the embossing device. At this time, the operator can easily move the embossing device through the pulley 21, preventing the operator from manually carrying it, thus bringing convenience to the movement operation of the embossing device. When the embossing device is moved to the designated position, the second electric push rod 19 can be activated again, causing the movable end of the second electric push rod 19 to drive the pulley 21 at the bottom of the moving block 20 to retract into the moving groove 18, allowing the support leg 17 to contact the ground and support the embossing device, ensuring the stability of the embossing device when placed and used.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
