DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figures 1-6The figure shows a stainless steel product production mold, including a base 1 and a pressing component 2. The top of the base 1 is provided with a lower mold groove 3, and a plurality of support columns 4 are evenly provided on the top of the base 1. The top of the base 1 is provided with an upper module 5, and the top of the support column 4 is fixed to the bottom of the upper module 5. The pressing component 2 for ejecting the stainless steel product from the lower mold groove 3 is arranged in the base 1, and the pressing component 2 includes a pressing block 6. The bottom of the lower mold groove 3 is symmetrically provided with a plurality of embedding grooves 7. The pressing block 6 is embedded in the embedding groove 7. A plurality of sealing grooves 8 are symmetrically provided in the base 1, and a piston plate 9 is slidably provided in the sealing groove 8. An air outlet 19 is provided on the side surface of the bottom of the sealing groove 8 to facilitate the smooth downward movement of the piston plate 9. The bottom end of the support column 4 passes through the top of the base 1 and is fixed to the piston plate 9. A plurality of serpentine grooves 10 are symmetrically provided in the base 1, and the serpentine groove 10 connects the sealing groove 8 and the embedding groove 7. A pushing component 11 for pushing the pressing block 6 to move is provided in the serpentine groove 10.

[0028] Some embodiments of the present application are described in detail below with reference to the accompanying drawings:

[0029] See also Figures 1-6 After the stainless steel product is pressed, as the upper module 5 rises, the piston plate 9 rises along with the support column 4, thereby compressing the air above the piston plate 9. The compressed air enters the serpentine groove 10 and squeezes the pushing component 11. The pushing component 11 applies force to the pressing block 6, thereby ejecting the product in the lower die groove 3 through the pressing block 6, without the need for additional manpower or tools.

[0030] Among them, such as Figure 2 As shown, the pushing component 11 includes a sliding block 12. There are two sliding blocks 12, which are respectively arranged at the two ends of the serpentine groove 10. The sliding blocks 12 are slidably engaged with the inside of the serpentine groove 10. A pressure rod 13 is fixed to the outside of the sliding block 12 close to the pressing block 6. The end of the pressure rod 13 away from the sliding block 12 is fixed to the pressing block 6, and the pressure block 6 is pushed to move by the force of air compression.

[0031] In addition, if Figure 2 As shown, a plurality of balls 14 are evenly arranged in the serpentine groove 10. The balls 14 are located between the two sliding blocks 12. The balls 14 are connected to the inside of the serpentine groove 10 in a rolling manner, so as to facilitate the transfer of the force exerted on one sliding block 12 to the other sliding block 12. The bottom of the middle section of the serpentine groove 10 is U-shaped, and the balls 14 can accumulate in the middle section of the serpentine groove 10 when stationary.

[0032] It is worth noting that a first compression spring 15 is provided on the outside of the pressure rod 13, one end of the first compression spring 15 is fixed to the sliding block 12, and the other end is fixed to the bottom of the bezel 7. Figure 3As shown, a sealing hole 16 communicating with the outside world is provided on the top side of the sealing groove 8, and a sealing plug 17 is provided on the inner thread of the sealing hole 16 to facilitate the complete embedding of the pressure block 6 in the embedding groove 7. A second compression spring 18 is provided on the outside of the support column 4, and one end of the second compression spring 18 is fixed to the top of the base 1, and the other end is fixed to the bottom of the upper module 5 to provide a buffer for the downward pressure of the upper module 5.

[0033] Further, such as Figure 2 and Figure 3 As shown, the piston plate 9 is located between the air outlet 19 and the interface between the serpentine groove 10 and the sealing groove 8, and the movable range of the piston plate 9 is controlled between the air outlet 19 and the interface between the serpentine groove 10 and the sealing groove 8 to avoid accidental leakage of air above the piston plate 9.

[0034] After the stainless steel product is pressed, as the upper die block 5 rises, the piston plate 9 rises together with the support column 4, thereby compressing the air above the piston plate 9. The compressed air enters the serpentine groove 10 and squeezes the sliding block 12. The sliding block 12 transmits the pressure to the other sliding block 12 through the ball 14, and then the other sliding block 12 squeezes the pressure rod 13 to apply force to the pressing block 6, driving the pressing block 6 to leave the embedding groove 7. As a result, the stainless steel product in the lower die groove 3 is ejected by the rising of the pressing block 6 without the use of additional manpower or tools.

[0035] Before the upper module 5 performs the downward pressing operation, the sealing plug 17 in the sealing hole 16 is unscrewed to allow the air pressure in the sealing groove 8 to be balanced with the outside world. At this time, under the action of the first compression spring 15, the pressing block 6 returns to the embedding groove 7, and the stainless steel is moved away and placed into the lower mold groove 3. Then the upper module 5 is used to press the mold downward, and finally the sealing plug 17 is reinserted into the sealing hole 16 to seal the sealing groove 8 so that the subsequent upward movement of the piston plate 9 can compress the air in the sealing groove 8.

[0036] See also Figures 1-4 In this embodiment, as Figure 5 As shown, the base 1 is provided with an annular groove 20, which is connected to each serpentine groove 10. Figure 1 and Figure 4 As shown, a fixed block 21 is fixed on the outside of the base 1, and an oil filling port 22 is provided in the fixed block 21. The oil filling port 22 is connected to the annular groove 20 to lubricate the ball 14. The inner diameter of the annular groove 20 is smaller than the inner diameter of the serpentine groove 10. The bottom of the annular groove 20 is flush with the lowest point of the serpentine groove 10 to avoid excessive oil filling and sealing the inside of the serpentine groove 10.

[0037] By setting an annular groove 20 in the base 1 to connect each serpentine groove 10, and injecting lubricating oil into the annular groove 20, the lubricating oil can provide lubrication for the ball 14, reduce the friction when the ball 14 rolls, and thereby reduce the wear of the ball 14 during movement.
