[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0033] Please refer to Figure 1-8A silver ingot processing and casting device comprises a frame 1 and at least one set of mold bearing mechanisms 2 slidably arranged on the frame 1, the frame 1 is provided with a driving mechanism 3 for driving the mold bearing mechanism 2 to move, the mold bearing mechanism 2 comprises a bearing frame 4, a combination mold 5 and a receiving groove 6 for avoiding the combination mold 5 are arranged in the middle of the bearing frame 4, and slide rail assemblies 7 for supporting the combination mold 5 are respectively arranged on the left and right sides of the bearing frame 4, and the slide rail assembly 7 comprises at least one row of pulleys 8 arranged front and back along the bearing frame 4. The bearing frame 4 supports the combination mold 5 through the slide rail assembly 7, so that the combination mold 5 can move on the bearing frame 4, which is convenient for demolding and assembling the combination mold 5. When casting, the silver paste is poured into the combination mold 5 for cooling and shaping.

[0034] The combined mold 5 includes templates 9 arranged in sequence front and back. The arrangement direction of the templates 9 is in line with the guide of the pulley 8 of the slide rail assembly 7, which is convenient for the separation and reorganization of the templates 9 one by one. A casting groove 10 is provided in the middle of the front end of the template 9, and a casting port 11 connected to the casting groove 10 is provided at the upper end of the template 9. The casting is the silver paste poured into the casting groove 10 through the casting port 11 for casting. The templates 9 arranged in sequence front and back form a closed state around the casting groove 10, which makes it easier to take out the silver ingot when demolding. Considering that the template 9 of the combined mold 5 is heavy and difficult to clamp and split, support arms 12 are respectively provided on both sides of the template 9, and the support arms 12 are respectively provided with mold-pulling holes 13. When demolding, the corresponding tool can be inserted into the mold-pulling hole 13 for pulling, and the support arms 12 on both sides of the template 9 are evenly stressed to pull the template 9 to achieve mold splitting.

[0035] Considering that the support arm 12 is mounted on the slide rail assembly 7 and there is a possibility of left-right deviation, a positioning block 14 is provided below the support arm 12, and at least one positioning wheel 15 supporting outward is provided on the positioning block 14, and a slideway 16 corresponding to the positioning wheel 15 is provided inside the slide rail assembly 7. Combined with the matching docking of the positioning wheel 15 and the slideway 16, the support arm 12 and the slide rail assembly 7 are positioned in the left-right direction, and the template 9 can be more stable when moving on the slide rail assembly 7.

[0036] The carrier frame 4 is also provided with a limiting component 17 for limiting the combined mold 5. The limiting component 17 includes a clamping shaft 18 movably arranged on the side of the carrier frame 4. The clamping shaft 18 can be extended into the interior of the carrier frame 4 to limit the movement of the template 9, so as to facilitate the mold separation of the combined mold 5 one by one. The outer end of the clamping shaft 18 is provided with a mounting block 19. The mounting block 19 can perform the telescopic movement of the clamping shaft 18 by connecting any existing cylinder.

[0037] The frame 1 is provided with parallel guide rails 20, and the bearing frame 4 is provided with a plurality of rollers 21 at positions corresponding to the guide rails 20, and the rollers 21 are matched and docked with the guide rails 20. Through the matching and docking of the rollers 21 and the guide rails 20, the entire mold bearing mechanism 2 can be moved along a predetermined track on the frame 1, so as to facilitate docking with different silver ingot processing procedures.

[0038] The driving mechanism 3 includes a lead screw 22 and a servo motor 23 for driving the lead screw 22 to rotate. The lead screw 22 is matched with a movable slide 24. The slide 24 is provided with a positioning cylinder 25 for upward output. The servo motor 23 described here is a motor that can rotate in both directions and can be implemented by any existing technology. The servo motor 23 can drive the slide 24 to drive the positioning cylinder 25 to move back and forth by reversing. A pull column 26 is fixed to the output end of the positioning cylinder 25. The bottom of the carrier 4 is provided with a plurality of pull grooves 27 corresponding to the travel trajectory of the pull column 26 and matching with the pull column 26. After the positioning cylinder 25 moves to a predetermined position, it drives the pull column 26 to rise and extend into the pull groove 27 for docking, so that the carrier 4 can be accurately positioned. Moreover, when the servo motor 23 is driven, it can drive the entire mold bearing mechanism 2 to move on the frame 1.

[0039] The frame 1 is provided with a slide groove 28 along the length direction of the lead screw 22 to accommodate the back and forth movement of the pull column 26 .

[0040] The frame 1 is also provided with a clamping mechanism 29 for clamping the combined mold 5, and the clamping mechanism 29 includes a pair of clamping assemblies 30 arranged opposite to each other. Considering that the casting trough 10 of the combined mold 5 is closed on all sides by the combination of the front and rear templates 9, the clamping assembly 30 is used to clamp the combined mold 5 front and back to prevent the silver paste from leaking through the gap between the templates 9 during casting, thereby ensuring the casting quality of the silver ingot.

[0041] The clamping assembly 30 includes a clamping cylinder 31 with an upward output arrangement, a clamping seat 32 is fixed to the output end of the clamping cylinder 31, an electric cylinder 33 is arranged on the clamping seat 32, and a clamping block 34 is arranged at the output end of the electric cylinder 33. The electric cylinder 33 can be implemented by any existing technology, and when clamping the combined mold 5, the two electric cylinders 33 arranged in opposite directions drive the clamping block 34 to squeeze the combined mold 5 forward and backward to improve the mold closing degree.

[0042] The output ends of the electric cylinder 33 of the clamping assembly 30 are arranged opposite to each other on the same straight line, and the pressing block 34 corresponds to the position of the combined mold 5.

[0043] Working principle:

[0044] The driving mechanism 3 drives the pull column 26 to dock with the pull groove 27 through the positioning cylinder 25, and drives the mold supporting mechanism 2 to move to the predetermined position through the servo motor 23 to realize the positioning and movement of the combined mold 5. The clamping mechanism 29 clamps the combined mold 5 through the relatively arranged electric cylinder 33. After the silver paste is poured, the driving mechanism 3 drives the combined mold 5 to leave.
