[0020] Embodiment

[0021] Please refer to Figures 1-4 As shown, the present utility model provides a vertical die-casting machine, which includes a machine body 1. A control console 2 is arranged on one side of the machine body 1. A fixed die 12 is arranged at the middle position of the top end of the machine body 1. Guide columns 6 are arranged at the four corners of the top end of the machine body 1. A guide sleeve 16 is sleeved on the outer part of the guide column 6 near the middle position, and the guide sleeve 16 can slide up and down on the outer part of the guide column 6. A lifting seat 7 is arranged between the outer parts of the guide sleeve 16. A top plate 8 is arranged between the top ends of the guide columns 6. A hydraulic cylinder 9 penetrates through the middle position of the top end of the top plate 8. The bottom end of the hydraulic cylinder 9 is fixedly connected to the middle position of the top end of the lifting seat 7. A moving die 17 is arranged at the middle position of the bottom end of the lifting seat 7. The hydraulic cylinder 9 drives the lifting seat 7 to rise and fall, and drives the moving die 17 to rise and fall to be combined with the fixed die 12 for die-casting workpieces. Compression blocks 19 are arranged on both sides of the moving die 17 at the bottom of the lifting seat 7. The compression blocks 19 are symmetrically arranged at the bottom of the lifting seat 7, and the bottom surface of the compression block 19 is lower than the bottom surface of the moving die 17. A compression spring 18 is arranged on the top of the compression block 19. The top end of the compression spring 18 is fixedly connected to the bottom end of the lifting seat 7. When the lifting seat 7 is driven to descend, the compression block 19 descends first, and the moving die 17 descends to contact the material, and the compression spring 18 is compressed to push the compression block 19 to tightly press and stabilize the material, ensuring the stability of the material during die-casting processing and guaranteeing the die-casting quality.

[0022] As a further implementation manner of this embodiment, as Figures 1-4As shown in the figure, a lifting guide rod 20 is inserted inside the compression spring 18 at the top of the pressing block 19. At the middle positions on both sides inside the lifting seat 7, there are stable through slots 11, and the stable through slots 11 are symmetrically arranged inside the lifting seat 7. The diameter of the lifting guide rod 20 is smaller than the inner diameter of the stable through slot 11. The top of the lifting guide rod 20 penetrates inside the stable through slot 11, and the lifting guide rod 20 can slide up and down relatively within the stable through slot 11. A limiting block 10 is provided at the top of the lifting guide rod 20, and the lifting guide rod 20 is limited within the stable through slot 11 by the limiting block 10. When the pressing block 19 is driven by the lifting seat 7 to descend and the compression spring 18 is compressed, the lifting guide rod 20 slides up relatively within the stable through slot 11 accordingly. When the pressing block 19 is driven to rise, the compression spring 18 rebounds and the lifting guide rod 20 slides down within the stable through slot 11 at the same time. In this way, the purpose of supporting and stabilizing the compression spring 18 and the pressing block 19 can be achieved, avoiding the compression spring 18 being bent under pressure, which may cause the bottom surface of the pressing block 19 to be skewed and affect the pressing effect;

[0023] During use, a lifting guide rod 20 is inserted into the compression spring 18 at the top of the pressing block 19, and the top of the lifting guide rod 20 penetrates through the stable through slot 11 provided inside the lifting seat 7. And the lifting guide rod 20 is limited within the stable through slot 11 by the limiting block 10. When the pressing block 19 is driven by the lifting seat 7 to descend and press the die-casting material, the compression spring 18 is compressed, and at the same time the lifting guide rod 20 slides up relatively within the stable through slot 11 accordingly. When the pressing block 19 is driven to rise, the compression spring 18 rebounds and the lifting guide rod 20 slides down within the stable through slot 11 at the same time, thereby supporting and stabilizing the compression spring 18 and the pressing block 19;

[0024] As a further implementation manner of this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a protection component is provided at the bottom of the front end of the machine body 1. The protection component includes a positioning groove 3. The positioning groove 3 is provided at the top of the front end of the machine body 1. At both ends between the two sides inside the positioning groove 3, there are sliding rods 5. The sliding rods 5 are symmetrically arranged between the two ends inside the positioning groove 3, and the sliding rods 5 are parallel to each other. A sliding seat 15 is provided on one side of the outside of the sliding rod 5, and the sliding seat 15 can slide horizontally on the outside of the sliding rod 5. A protection baffle 13 is provided between the front ends of the sliding seats 15. The position of the protection baffle 13 can be slid left and right through the sliding cooperation between the sliding seat 15 and the sliding rod 5. A transparent window 14 is provided at the top inside the protection baffle 13, which is convenient for workers to view the die-casting process through the transparent window 14. A pressure sensor 4 is provided at the middle position of the front end on one side inside the positioning groove 3. During die-casting work, the protection baffle 13 is pulled to the leftmost side to block in front of the die-casting station, and the die-casting machine can be started to perform die-casting material operation only after the pressure sensor 4 senses the pressure applied to the left by the protection baffle 13. Thus, the anti-fooling function of the die-casting machine is optimized, the safety performance of the die-casting machine is further improved, and the feasibility is strong;

[0025] During use, the position of the protective baffle 13 can be slid left and right through the sliding fit between the sliding seat 15 and the sliding rod 5. When die-casting work is in progress, the protective baffle 13 is pulled to the leftmost side to block in front of the die-casting station, and the die-casting machine can be started to perform die-casting material operation only after the pressure sensor 4 senses the pressure applied by the protective baffle 13 to the left. During die-casting, the die-casting process can also be viewed through the transparent window 14. After die-casting is completed, the protective baffle 13 is slid to the right to pick up and place the workpiece;

[0026] Specific working principle:

[0027] When using a vertical die-casting machine, first, the die-casting workpiece is placed on the fixed die 12. Subsequently, through the sliding fit between the sliding seat 15 and the sliding rod 5, the protective baffle 13 is pulled to the leftmost side to block in front of the die-casting station, and the die-casting machine can be started to perform die-casting material operation only after the pressure sensor 4 senses the pressure applied by the protective baffle 13 to the left. The hydraulic cylinder 9 is driven by the control console 2 to drive the lifting seat 7 to lift and drive the moving die 17 to lift and close the die with the fixed die 12 for die-casting the workpiece. At the same time, the guide sleeve 16 slides outside the guide post 6 to stably guide the lifting seat 7 and the moving die 17. When the lifting seat 7 is driven to descend, the pressure block 19 descends first, and the moving die 17 descends to contact the material and presses the stable material by the elastic force of the compressed spring 18. At the same time, the lifting guide rod 20 slides upward relatively in the stable through groove 11. During die-casting, the worker can view the die-casting process through the transparent window 14. After the die-casting process is completed, the pressure block 19 is driven to rise to compress the spring 18 to reset and rebound, and the lifting guide rod 20 slides downward in the stable through groove 11 at the same time to support and stabilize the compressed spring 18 and the pressure block 19. Subsequently, the protective baffle 13 is slid to the right to take out the die-cast workpiece.
