Description

Technical Field

[0001] The invention relates to the technical field of drug column production equipment, in particular to a drug pressing mold with a component for pressing drugs. Background Art

[0002] For the compression molding of the main and auxiliary powder columns of a certain type of small-caliber armor-piercing rocket warhead, the remaining components are usually assembled after compression. Because they need to be assembled with the components after compression, and the components have certain tolerances, the assembly difficulty increases, the powder surface cannot be seamlessly attached to the components, and left and right friction and shaking will occur during use and firing, which reduces the quality of the product. Therefore, the present invention provides a powder pressing mold with component powder pressing. Summary of the invention

[0003] Based on this, the purpose of the present invention is to provide a gas-controlled shell automatic charge pressing device to solve the technical problems raised in the above background.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a medicine pressing mold with components for pressing medicine, comprising a base, a mold shell installed on the base, and a lower punch assembly installed in the mold shell, wherein a shell with a bushing and an insulating gasket are also installed in the mold shell, and the shell with a bushing and the insulating gasket are pressed into the mold shell by a shell pressure head, and also comprises an auxiliary medicine pressing rod, an auxiliary mold sleeve, a main mold sleeve, an upper punch and an upper punch, the auxiliary mold sleeve cooperates with the mold shell, and the upper punch and the upper punch are assembled into a main medicine column pressing rod.

[0005] Furthermore, the lower punch assembly includes a lower punch, a lower punch, a lower punch rod, a small spring and a large spring. The lower punch cooperates with the partition assembly, the lower punch rod cooperates with the drug cover with terminal posts, the small spring cooperates with the lower punch rod, and the large spring cooperates with the lower punch.

[0006] Furthermore, it also includes a medicine withdrawal mold base, which matches the mold shell after replacing the base.

[0007] Preferably, the base is placed on a working table of the hydraulic press.

[0008] In summary, the present invention mainly has the following beneficial effects:

[0009] The present invention connects the lower punch body and the lower punch rod with the assembly so that the powder column and the warhead assembly are closely matched after the pressing is completed without burrs, thereby improving the quality of the pressed powder.

[0014] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0015] The following describes an embodiment of the utility model based on its overall structure.

[0016] like Figure 1-Figure 3 As shown, the present invention includes a base 4, a mold shell 3 installed on the base 4, and a lower punch assembly installed in the mold shell 3. A shell body 13 with a bushing and an insulating gasket 14 are also installed in the mold shell 3. The shell body 13 with a bushing and the insulating gasket 14 are pressed into the mold shell 3 through a shell pressing head 15. The present invention also includes an auxiliary medicine pressing rod 1, an auxiliary mold sleeve 2, a main mold sleeve 10, an upper punch 11 and an upper punch 12. The auxiliary mold sleeve 2 cooperates with the mold shell 3, and the upper punch 11 and the upper punch 12 are assembled into a main medicine column pressing rod.

[0017] The lower punch assembly of the present invention comprises a lower punch 5, a lower punch 6, a lower punch rod 7, a small spring 8 and a large spring 9. The lower punch 6 cooperates with the partition assembly, the lower punch rod 7 cooperates with the medicine cover 15 with a terminal post, the small spring 8 cooperates with the lower punch rod 7, and the large spring 9 cooperates with the lower punch 6.

[0018] During the working process of the present invention, the base 4 is first installed on the working table of the hydraulic press, and then the mold shell 3 and the base 4 are sleeved together, and the assembled lower punch assembly is placed in the mold shell 3, and the shell with bushing 13 and the insulating gasket 14 are pressed into the mold through the shell pressure head 15. At this time, the lower punch 6 and the lower punch rod 7 are in an elongated state; when pressing the auxiliary medicine column, the auxiliary mold sleeve 2 is matched with the mold shell 3, the lower punch 6 is matched with the partition assembly, and the weighed medicine is poured in, and the auxiliary medicine pressing medicine rod 1 is pressed into shape; then the main medicine column 16 is pressed, and the auxiliary medicine pressing medicine rod 1 and the auxiliary mold sleeve 2 are taken out. Before pressing, the upper punch 11 and the upper punch 12 are assembled into the main medicine column pressing medicine rod, the main mold sleeve 10 is matched with the mold shell 3, the lower punch rod 7 is matched with the medicine cover with terminal 15, the medicine is poured in, and the main medicine column pressing medicine rod is pressed into shape; Figure 3As shown, after pressing and molding, the base 4 is replaced with the medicine ejection mold base 13, and the medicine ejection mold is inverted for ejection. After ejection, the warhead assembly of a certain type of armor-piercing rocket projectile and the medicine column are tightly matched, and there will be no left and right friction and shaking during the firing process.
