The inside of the pressing groove 16 is slidably connected with the elastic spring 17. The elastic spring 17 is charged by pressing the pressing block 18 inward. When the pressing block 18 is pressed to the bottom of the pressing groove 16, the adjusting rod 10 is released from the limit, and the positioning plate 11 fixedly connected to the adjusting rod 10 is contacted with the limit. At this time, the positioning plate 11 is moved to a position suitable for ejecting the casting shell 7, and the pressing block 18 is pressed against the bottom of the pressing groove 16. The ejection outlet 15 is accurately ejected, and the elastic force stored in the elastic spring 17 is released at this time, driving the pressing block 18 to pop out into the ejection outlet 15, so that the position of the adjusting rod 10 is limited, thereby fixing the position of the positioning plate 11, and then starting the ejection mechanism 6 to eject the lead-free tin bar. During the ejection process, the burrs on the edge of the positioning plate 11 can be scraped off, so that the burrs do not need to be manually removed after the lead-free tin bar is cast, thereby improving the casting efficiency of the lead-free tin bar and reducing the tediousness of the operation of the staff.

The interior of the second sliding groove 20 is slidably connected to the second slider 21. Through the setting of the second sliding groove 20 and the second slider 21, the adjusting rod 10 can form a stable guiding effect when moving inside the fixed rod 9, preventing the occurrence of deviation and causing the pressing block 18 to be unable to normally pop out from the ejection outlet 15, thereby affecting the position fixation of the positioning plate 11.

By setting the return spring 22, the adjusting rod 10 can rebound quickly after the limit is released, so that the position of the positioning plate 11 can be quickly released from the limit, thereby achieving convenient adjustment of the positioning plate 11.
[0030] Reference Figure 3 As shown, in this embodiment: the cleaning blade 12 is made of cemented carbide, which has greater pressure resistance and friction resistance. During use, the cleaning blade 12 will not be damaged due to frequent friction, thereby improving the service life of the cleaning blade 12.
[0031] Reference Figure 3 and Figure 7 As shown, in the present embodiment: a first connecting plate 23 is fixed to one side of the positioning plate 11, a threaded rod 24 is connected to the internal thread of the first connecting plate 23, a rotating plate 25 is fixed to the top of the threaded rod 24, a second connecting plate 26 is fixed to one side of the burr storage bin 14, a limiting hole 27 is provided on the surface of the second connecting plate 26, when the staff needs to process the burrs in the burr storage bin 14, the rotating plate 25 is rotated upward to drive the threaded rod 24 to rotate out, so that the burr storage bin 14 is released from the limit, and then the burr storage bin 14 is pulled out, and the burr storage bin 14 is pushed back after cleaning, and the threaded rod 24 is aligned with the limiting hole 27 and rotated in, so that the burr storage bin 14 is limited, thereby achieving rapid processing of the burrs stored in the burr storage bin 14.
[0032] Reference Figure 7 As shown, in the present embodiment: a third slide groove 28 is provided inside the sliding opening 13, a third slider 29 is fixed to the end of the burr storage bin 14 away from the casting shell 7, the inside of the third slide groove 28 is slidably connected to the third slider 29, and through the arrangement of the third slide groove 28 and the third slider 29, the burr storage bin 14 can be firmly limited during the pulling-out process to prevent the internal burrs from being scattered due to deviation and affecting the cleanliness of the table top.
[0033] Reference Figure 8As shown, in the present embodiment: a lubricating oil storage bin 30 is installed at the bottom end of the lower pressure plate 3, and the number of the lubricating oil storage bins 30 is four. A delivery pipe 31 is installed at one end of the lubricating oil storage bin 30 close to the first positioning rod 2. Through the arrangement of the lubricating oil storage bin 30 and the delivery pipe 31, the lubricating oil can be regularly added to the surface of the first positioning rod 2 during the pressing process of the lower pressure plate 3, so that the lower pressure plate 3 is smoother during the pressing process, thereby improving the overall operation speed of the device.
[0034] Working principle: By pressing the pressing block 18 inward to store force in the elastic spring 17, when the pressing block 18 is pressed to the bottom of the pressing groove 16, the adjusting rod 10 is released from the limit, and at the same time, the positioning plate 11 fixedly connected to the adjusting rod 10 is contacted with the limit. At this time, the positioning plate 11 is moved to a position suitable for ejecting the casting shell 7, and the pressing block 18 is aligned with the ejection outlet 15. The elastic force stored in the elastic spring 17 is released at this time, driving the pressing block 18 to pop out into the ejection outlet 15, so that the position of the adjusting rod 10 is limited, thereby fixing the position of the positioning plate 11, and then starting the ejection mechanism 6 to eject the lead-free tin strip. During the ejection process, the positioning plate 11 is used to push the lead-free tin strip out of the casting shell 7. The setting can scrape off the burrs on the edge, so that after the lead-free tin bar is cast, there is no need to manually remove the burrs, thereby improving the casting efficiency of the lead-free tin bar and reducing the cumbersomeness of the operation of the staff. The setting of the first slide groove 19 and the first slider 32 can prevent the adjusting rod 10 from shaking due to the elastic force of the elastic spring 17 during the fixing process, thereby improving the fixing effect of the positioning plate 11, thereby improving the burr removal efficiency of the lead-free tin bar. The setting of the second slide groove 20 and the second slider 21 can form a stable guiding effect when the adjusting rod 10 moves inside the fixing rod 9, thereby preventing the offset from causing the pressing block 18 to be unable to normally pop out of the ejection outlet 15, thereby The positioning plate 11 is fixed in position and the reset spring 22 is set so that the adjusting rod 10 can rebound quickly after the limit is released, so that the position of the positioning plate 11 can be quickly released, thereby achieving convenient adjustment of the positioning plate 11. The cemented carbide has greater pressure resistance and friction resistance. During use, the cleaning blade 12 will not be damaged due to frequent friction, thereby improving the service life of the cleaning blade 12. When the staff needs to deal with the burrs in the burr storage bin 14, the rotating plate 25 is rotated upward to drive the threaded rod 24 to rotate out, so that the burr storage bin 14 is released from the limit, and then the burr storage bin 14 is pulled out, and the cleaning is completed. Then, the burr storage bin 14 is pushed back, and the threaded rod 24 is aligned with the limiting hole 27 and rotated in, so that the burr storage bin 14 is limited, thereby achieving rapid processing of the burrs stored in the burr storage bin 14. Through the setting of the third slide groove 28 and the third slider 29, the burr storage bin 14 can form a stable limit in the process of pulling out to prevent the internal burrs from being scattered due to deviation and affecting the cleanliness of the table top. Through the setting of the lubricating oil storage bin 30 and the conveying pipe 31, the lower pressure plate 3 can regularly add lubricating oil to the surface of the first positioning rod 2 during the pressing process, so that the lower pressure plate 3 is smoother during the pressing process, thereby improving the overall operating speed of the device.
