Description

Technical Field

[0001] The utility model relates to the technical field of precious metals, in particular to a mold removing and silver taking device for silver ingot processing. Background Art

[0002] In the casting process of silver ingots, there are various casting processes and molds that are suitable according to the weight requirements of the silver ingots. Among the existing casting processes, there is a combination mold method, in which a casting trough for accommodating silver ingots is opened between adjacent templates, and multiple templates are arranged to form a combination mold that can continuously cast multiple silver ingots. The weight of the cast silver ingots is relatively high, and the weight of the relative combination mold far exceeds the weight of the silver ingot. The existing method of dismantling the mold and taking out the silver is still mainly manual disassembly, in which workers remove the templates and silver ingots one by one from the combination mold, which has low work efficiency and poses safety hazards. Therefore, we urgently need a device that can automatically disassemble the mold and remove the silver ingots to improve production efficiency and reduce the risk of personal injury.

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.

[0030] Please refer to Figure 1-12 A silver ingot processing mold removal and silver taking device comprises a frame 1, on which a lifting mechanism 2 and a pressing mechanism 3 are arranged, the lifting mechanism 2 is used to take out the silver ingot after mold removal, and the pressing mechanism 3 is used to press the silver ingot when the mold is removed, a mold bearing mechanism 4 is arranged on the frame 1 below the lifting mechanism 2 and the pressing mechanism 3, the silver ingot after casting is placed on the mold bearing mechanism 4 and transported by the mold bearing mechanism 4, corresponding linear modules 5 are arranged on the frames 1 on both sides of the mold bearing mechanism 4, the combined mold of the silver ingot is disassembled by the linear modules 5, a silver removal component 31 is obliquely arranged on the pressing mechanism 3, and the demolding of the silver ingot is carried out by the silver removal component 31.

[0031] The lifting mechanism 2 includes a lifting cylinder 51 fixed on the frame 1. The installation direction of the lifting cylinder 51 is vertical downward output. The output end of the lifting cylinder 51 is connected to a lifting platform 6. A rotating cylinder 7 is fixed below the lifting platform 6. The output end of the rotating cylinder 7 is connected to a clamping assembly 8. When taking the silver ingot, the silver ingot is clamped by the clamping assembly 8, and the direction of the silver ingot is changed by the rotating cylinder 7 to facilitate placement. The lifting cylinder 51 drives the lifting platform 6 to move up and down to drive the entire silver ingot to move up and down. The role played by the lifting mechanism 2 is the material taking role.

[0032] The clamping assembly 8 includes a double-acting cylinder 9. The double-acting cylinder 9 described here means that the cylinder has two output ends arranged in opposite directions, which can be implemented by any existing technical method. The two output ends of the double-acting cylinder 9 extending in opposite directions are respectively connected to clamping plates 10. When the output ends of the double-acting cylinder 9 shrink, the two clamping plates 10 clamp the silver ingot. The outer side of the double-acting cylinder 9 is connected to a vacuum suction cup 11. The vacuum suction cup and the double-acting cylinder are fixedly connected. The two are not connected by an air flow channel and are independent individuals. The vacuum suction cup 11 performs a vacuuming action through an external air flow pipeline. The vacuum suction cup can be implemented by any existing technical method. The vacuum suction cup 11 and the clamping plate 10 form a three-sided wrapping state, thereby performing adsorption and clamping forces on the silver ingot at the same time. Considering the weight of the silver ingot, this clamping method can achieve a more stable clamping requirement and prevent the silver ingot from falling off midway.

The output end of the pressing cylinder 12 is connected to a pressing table 13, and a pressing block 14 that can swing left and right is hinged below the pressing table 13.

A positioning block 32 is provided below the support arm 29, and at least one positioning wheel 33 supporting outward is provided on the positioning block 32. The positioning wheel 33 can reduce friction. At the same time, the positioning wheels 33 symmetrical on both sides support outward to position the template 26 to prevent the template 26 from offset when demolding.

[0037] The limiting assembly 23 includes a clamping shaft 34 movably arranged on the side of the carrier 19, and the clamping shaft 34 can move along its axial direction. A limiting block 35 is arranged at the outer end of the clamping shaft 34, and a limiting cylinder 36 is arranged on the frame 1.

The slide 40 is linked to the screw (the screw is not shown in the figure). The mold frame body 39 is connected to a driving motor 41 that drives the screw transmission. The slide 40 can be driven to move by the driving motor 41. The linear module 5 can be implemented in any existing manner. A demolding assembly 42 is fixed on the slide 40.

The output end of the mold removal cylinder 44 is connected to a material removal shaft 45. When removing the mold, the mold removal cylinder 44 drives the material removal shaft 45 to extend into the mold removal hole 30 for matching installation. When the slide 40 drives the mold removal frame 43 to move, it moves the template 26 to open the mold.

[0040] A fixed mold mechanism 46 is also provided at the bottom of the frame 1, and the fixed mold mechanism 46 includes a slide cylinder 47. The output platform of the slide cylinder 47 is connected to an upwardly arranged fixed mold cylinder 48, and the output end of the fixed mold cylinder 48 is connected to a fixed mold column 49.
