Description

Technical Field

[0001] This utility model relates to the field of industrial mold technology, and more specifically, to a multi-lobed conical bolus pressing mold. Background Technology

[0002] A multi-lobed conical propellant die generally refers to a mold used to press conical propellant charges with a multi-lobed structure. This mold is designed to solve problems existing in the traditional manufacturing process of conical propellant charges, such as the difficulty of human-machine separation during cutting, the waste of raw materials caused by cutting waste, and potential safety hazards during the cutting process. By adopting a multi-lobed structure, the multi-lobed conical propellant die can directly press propellant charges with the required shape and size without subsequent cutting processing, thereby improving production efficiency and safety, and reducing raw material waste. Propellant charges are usually formed by pressing explosive powder or granules. For conical propellant charges, the traditional method is to manually cut them into shape using a machine tool after pressing them into cylinders. Although safety protection measures are taken during the cutting process, true human-machine separation and machine replacement cannot be achieved, posing safety hazards. In addition, the cutting process generates heat, further increasing the risk. At the same time, the waste generated during cutting not only increases the workload but also wastes a large amount of raw materials, which needs to be centrally disposed of, undoubtedly a waste of resources. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a multi-lobed conical propellant compression mold, which has the advantages of facilitating effective isolation between people and hazardous materials and human-machine isolation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-lobed conical drug-pressing mold, comprising a lower template, a cavity fixing sleeve fixedly installed on the top of the lower template, and cavities one, two, three, and four sequentially installed inside the cavity fixing sleeve, wherein cavities one, two, three, and four form a cavity, a drug-pressing mold movably installed inside cavities one, two, three, and four, and a drug-pressing rod fixedly installed inside the drug-pressing mold, with an upper template fixedly installed on the bottom outer surface of the drug-pressing rod.

[0005] As a preferred embodiment of this utility model, the outer diameter of the pressing mold is equal to the inner diameter of cavity one, cavity two, cavity three, and cavity four, and cavity one, cavity two, cavity three, and cavity four have a smooth surface design.

[0007] As a preferred embodiment of this utility model, the lower template has a first limiting hole inside, and the upper template has a second limiting hole inside.

[0008] As a preferred technical solution of this utility model, the pressing mold has a conical shape at one end of the pressing rod, and the outer surface of the pressing mold has a smooth surface design.

[0009] As a preferred embodiment of this utility model, the height of both the lower template and the upper template is 20 mm, and the width of both the lower template and the upper template is 200 mm.

[0010] As a preferred embodiment of this utility model, the height of the cavity fixing sleeve is 65 mm, and the inside of the cavity fixing sleeve is inclined at 20 degrees.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Compared with traditional drug molds, this invention achieves effective isolation between personnel and hazardous materials, as well as human-machine isolation, through the cooperation between the pressing mold and cavities one, two, three, and four, ensuring inherently safe production. The pressing mold adopts a conical surface structure for mold closing, which not only simplifies the mold structure but also ensures high mold closing accuracy and inconspicuous mold parting lines, avoiding flash. This simplifies the mold structure and improves the quality of pressing. This pressing method can form conical drug columns in one go. After forming, the cavity and drug column can be directly separated, avoiding the problem of the cavity and fixed sleeve locking due to pressing pressure, making demolding easy.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 3 As shown, this utility model provides a multi-lobed conical drug-pressing mold, including a lower template 1. A cavity fixing sleeve 8 is fixedly installed on the top of the lower template 1. Cavities 1 3, 2 4, 3 5, and 4 6 are sequentially installed inside the cavity fixing sleeve 8, and the interiors of 3, 4, 5, and 6 form a cavity. A drug-pressing mold 7 is movably installed inside 3, 4, 5, and 6. A drug-pressing rod 2 is fixedly installed inside the drug-pressing mold 7. An upper template 9 is fixedly installed on the bottom outer surface of the drug-pressing rod 2.

[0019] Workers sequentially install cavity 1 (3), cavity 2 (4), cavity 3 (5), and cavity 4 (6) into the cavity fixing sleeve 8. By assembling these components into a complete cavity within the fixing sleeve 8, pre-weighed explosives are poured into this assembled cavity, completing the loading process. The operators leave the loading room, and the hydraulic press in the control room is activated. The hydraulic press drives the pressing rod 2 and the upper template 9 downwards. The pressing rod 2 then drives the pressing mold 7 to move downwards synchronously. 7. Apply pressure to the explosive powder or particles in the cavity to compress it into the required shape, and maintain sufficient pressure for a sufficient time to ensure the stability and density of the compression mold 7. After compression is completed, the compression rod 2 is lifted and returned to the initial position. At this time, the operator can re-enter the compression chamber and remove the cavities containing the formed explosive charge (cavity 1 3, cavity 2 4, cavity 3 5, and cavity 4 6) from the cavity fixing sleeve 8. Finally, open each cavity and remove the formed compression mold 7 one by one. Thus, the entire compression process is completed.

[0020] Cavity 1 (3), Cavity 2 (4), Cavity 3 (5), and Cavity 4 (6) are sequentially installed into the cavity fixing sleeve 8 to form a complete cavity system. Then, the pre-weighed explosive is poured into this assembled cavity, completing the loading step. Next, the operator leaves the pressing room. After ensuring safety, the hydraulic press is started in the control room. The hydraulic press drives the pressing rod 2 downwards, simultaneously lowering the pressing mold 7, applying uniform pressure to the explosive powder or particles in the cavity to compress it into the desired shape. Sufficient pressure is maintained during the pressing process to ensure the stability and density of the explosive charge. After pressing is complete, the pressing rod 2 is raised and returned to its initial position. At this point, the operator can re-enter the pressing room and remove the four cavities containing the formed drug column from the cavity fixing sleeve 8. Finally, each cavity is opened one by one, and the formed drug column is removed from the pressing mold 7. Compared with traditional drug molds, this mold, through the cooperation between the pressing mold 7 and cavities 3, 4, 5, and 6, effectively isolates personnel from hazardous materials and ensures inherently safe production. The pressing mold 7 adopts a conical surface structure for mold closing, which not only has a simple mold structure but also high mold closing accuracy and a clean mold line. The defects are not obvious, avoiding flash, simplifying the mold structure and improving the quality of drug pressing. This drug pressing method can form a conical drug column in one go. After forming, the cavity and the drug column can be directly separated, avoiding the problem of the cavity and the fixed sleeve locking due to the drug pressing pressure. It is easy to demold. The design of cavity 1 (3), cavity 2 (4), cavity 3 (5), and cavity 4 (6) accelerates the demolding process of the drug column and reduces the risk of drug column damage. After mold pressure test verification, this design can successfully press the drug column in one go, solving the problems of difficult forming of conical drug columns and difficult demolding.

[0021] Among them, the outer diameter of the pressing mold 7 is equal to the inner diameter of cavity 1 3, cavity 2 4, cavity 3 5, and cavity 4 6, and cavity 1 3, cavity 2 4, cavity 3 5, and cavity 4 6 have a smooth surface design.

[0022] Since the outer diameter of the compression mold 7 is equal to the inner diameter of cavity 3, cavity 4, cavity 5, and cavity 6, and cavity 3, cavity 4, cavity 5, and cavity 6 have a smooth surface design, it is convenient for the inside of the compression mold 7 to move up and down, thereby improving the efficiency of extruding explosives.

[0023] Both the lower template 1 and the cavity fixing sleeve 8 have threaded holes 11 inside, and bolts 10 are threaded into the threaded holes 11.

[0024] The worker holds bolt 10 and slowly screws it into the threaded hole 11 and the inside of the worktable. The bolt 10 stabilizes the lower template 1 and the cavity fixing sleeve 8 on the worktable, ensuring the stability of the cavity fixing sleeve 8 during use.

[0025] The lower template 1 has a first limiting hole 12 inside, and the upper template 9 has a second limiting hole 13 inside.

[0026] The fit between the second limiting hole 13 and the first limiting hole 12 facilitates the limiting of the lower template 1 and the upper template 9, ensuring the stability of the upper template 9 during its up-and-down movement and improving the efficiency of its use.

[0027] The pressing mold 7 has a conical shape at one end of the pressing rod 2, and the outer surface of the pressing mold 7 has a smooth design.

[0028] Because the outer surface of the pressing mold 7 has a smooth design, and the pressing mold 7 is in the shape of a cone inside the pressing rod 2, the pressing mold 7 adopts a conical surface structure for mold closing. This design makes the mold structure simpler, significantly improves the mold closing accuracy, ensures that no obvious mold closing line is generated during the mold closing process, and effectively avoids flash phenomenon, thereby simplifying the overall complexity of the mold and greatly improving the quality of pressing medicine.

[0029] The height of both the lower template 1 and the upper template 9 is 20 millimeters, and the width of both the lower template 1 and the upper template 9 is 200 millimeters.

[0030] Since the height of both the lower template 1 and the upper template 9 is 20 mm and the width of both the lower template 1 and the upper template 9 is 200 mm, the uniform and moderate template design, with the lower template and the upper template both having a height of 20 mm, significantly improves the stability and consistency of the pressing process, thereby ensuring the high forming accuracy of the pressing mold 7 and avoiding deviations caused by inconsistent heights. At the same time, the width of the lower template 1 and the upper template 9 reaches 200 mm, which effectively enhances the overall strength and rigidity of the mold, enabling it to better withstand the huge pressure during the pressing process, preventing deformation and damage, and extending its service life.

[0031] The cavity fixing sleeve 8 has a height of 65 mm and its interior is inclined at 20 degrees.

[0032] Since the cavity fixing sleeve 8 has a height of 65 mm and its interior is inclined at 20 degrees, it has significant advantages in optimizing the shape and density of the pressing mold 7, improving production efficiency, enhancing structural stability, and adapting to complex-shaped pressing molds 7. This design helps to improve the overall quality and combustion performance of the propellant, providing strong support for the development of the gunpowder manufacturing field.

[0033] Working principle and usage process of this utility model:

[0034] Workers sequentially install cavity 1 (3), cavity 2 (4), cavity 3 (5), and cavity 4 (6) into the cavity fixing sleeve 8. By assembling these components into a complete cavity within the fixing sleeve 8, pre-weighed explosives are poured into this assembled cavity, completing the loading process. The operators leave the loading room, and the hydraulic press in the control room is activated. The hydraulic press drives the pressing rod 2 and the upper template 9 downwards. The pressing rod 2 then drives the pressing mold 7 to move downwards synchronously. 7. Apply pressure to the explosive powder or particles in the cavity to compress it into the required shape, and maintain sufficient pressure for a sufficient time to ensure the stability and density of the compression mold 7. After compression is completed, the compression rod 2 is lifted and returned to the initial position. At this time, the operator can re-enter the compression chamber and remove the cavities containing the formed explosive charge (cavity 1 3, cavity 2 4, cavity 3 5, and cavity 4 6) from the cavity fixing sleeve 8. Finally, open each cavity and remove the formed compression mold 7 one by one. Thus, the entire compression process is completed.
