[0021] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0022] Please refer to Figure 1-Figure 4 As shown, a fast-mold-changing tablet press for producing fludrocortisone acetate tablets. Fludrocortisone acetate is obtained by mixing, reacting and drying various pharmaceutical agents to obtain fludrocortisone acetate powder, which then needs to be pressed into fludrocortisone acetate tablets for easy administration. The tablet press includes a workbench 1 and a lower mold 12. A back plate 2 is vertically arranged on the top rear side of the workbench 1. A crossbeam 3 is fixed on the upper front side of the back plate 2. A cylinder A4 is arranged on the top of the crossbeam 3. The crossbeam 3 can keep the cylinder A4 in a suspended state. Four columns 5 are symmetrically arranged on the upper surface of the workbench 1. The tops of the four columns 5 are smooth and free of obstacles. An upper mold 6 is slidably installed between the four columns 5. When installing, the upper mold 6 can be directly slid in through the top. The output end of the cylinder A4 is fixed on the upper surface of the upper mold 6. The center of the surface is formed, and the movement of the upper mold 6 is controlled by the cylinder A4. The lower surface of the upper mold 6 is evenly provided with pressure columns 61. The upper surface of the workbench 1 is fixed with a boss 7. The lower mold 12 is placed on the rear side of the boss 7. The upper surfaces of the lower mold 12 and the boss 7 are flush to facilitate the sliding of the material box 9. The upper surface of the lower mold 12 is evenly provided with a mold groove 121. The pressure column 61 is adapted to the internal size of the mold groove 121. When tableting is performed, the pressure column 61 will enter the inside of the mold groove 121 to compress the medicinal powder by extrusion.

[0023] Please refer to Figure 1-Figure 5 As shown, extension rods 15 are symmetrically arranged on both sides of the boss 7, the lower mold 12 is placed between the two extension rods 15, and positioning holes 123 are symmetrically opened on the side surface of the lower mold 12. A mounting tube 16 is arranged at the end of the extension rod 15, and the mounting tube 16 corresponds to the position of the positioning hole 123. A positioning bolt 17 is slidably installed on the inner side of the mounting tube 16, and the end of the positioning bolt 17 is set to be hemispherical. The hemispherical structure can squeeze the positioning bolt 17 when the lower mold 12 is pushed close to the boss 7, so that the internal spring 19 accumulates force. After being installed in place, the positioning bolt 17 enters the inside of the positioning hole 123 to achieve cooperation, so as to fix the lower mold 12.

[0024] Among them, a connecting rod 18 is provided on the end of the positioning bolt 17 facing away from the lower mold 12, and the connecting rod 18 passes through the mounting tube 16. A pulling and twisting device 20 is provided on the end of the connecting rod 18 facing away from the positioning bolt 17. The pulling and twisting device 20 is placed on the outside of the mounting tube 16 to facilitate the separation of the positioning bolt 17 from the positioning hole 123 by pulling the positioning bolt 17 from the outside, so as to facilitate the disassembly of the lower mold 12. A spring 19 is sleeved on the surface of the connecting rod 18, and the spring 19 is placed inside the mounting tube 16, and one end of the spring 19 is in contact with the positioning bolt 17.

[0025] Please refer to Figure 1 A cylinder B8 is provided on the front side of the workbench 1, a material box 9 is slidably mounted on the upper surface of the boss 7, an output end of the cylinder B8 is fixed on the material box 9, and medicinal powder is placed inside the cylinder B8. Before pressing, the cylinder B8 pushes the material box 9 to slide back and forth, and at this time, the medicinal powder inside the material box 9 will automatically fill the multiple mold grooves 121.

[0026] Please refer to Figure 2 As shown, a through groove 10 is provided on the workbench 1, and a discharge guide plate 11 is provided on one side of the workbench 1. The discharge guide plate 11 is placed below the through groove 10, and the through groove 10 is placed below the die groove 121. A slide groove 122 is provided at the bottom of the lower die 12, and a baffle 14 is slidably installed on the inner side of the slide groove 122. The baffle 14 seals the bottoms of multiple die grooves 121. A cylinder C13 is provided on the rear side of the upper surface of the workbench 1, and the output end of the cylinder C13 is fixed on one side of the baffle 14. After compression molding, the baffle 14 can be pulled backward by the cylinder C13, and then the bottom of the die groove 121 is no longer blocked. At this time, the tablets will fall into the through groove 10 and be guided out through the discharge guide plate 11 at the bottom.

[0027] The working principle of the utility model is as follows: the medicine powder is poured into the material box 9, and the material box 9 can be pushed to slide by the cylinder B8. When the material box 9 moves to the die groove 121, the medicine powder will automatically fill the die groove 121. At this time, the baffle 14 seals the die groove 121. After filling, the material box 9 returns to the front side, and the cylinder A4 controls the upper mold 6 to move down, so that the pressure column 61 enters the die groove 121 to press the medicine powder in the die groove 121 into shape. After tableting, the upper mold 6 moves up, and then the cylinder C13 controls the baffle 14 to move backward, and no longer blocks the bottom of the die groove 121. At this time, the formed tablets will fall to the through hole. Inside the groove 10, the equipment is guided out by the discharge guide plate 11. When changing the mold, the upper mold 6 can be directly disassembled from the output end of the cylinder A4, the upper mold 6 can be taken out through the top of the column 5, and a new mold can be replaced. Due to the existence of the column 5, the new upper mold 6 can be limited after being installed in place and can only move in the vertical direction. When replacing the lower mold 12, the pull-twist 20 on both sides can be pulled outward at the same time to make the positioning bolt 17 disengage from the positioning hole 123. At this time, the lower mold 12 can be extended. When replacing the new lower mold 12, the elastic force of the spring 19 can be used to make the positioning bolt 17 cooperate with the positioning hole 123 to fix the new lower mold 12.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
