Description

Technical Field

[0001] The utility model is a press-in primer disassembly die, belonging to the technical field of weapon manufacturing. Background Art

[0002] At present, when a misfire occurs during shooting, the primer is usually checked by filling the cartridge case with water, placing a steel ring at the bottom of the cartridge case with the primer in the center of the ring, and then placing a punch with a slightly larger diameter at the mouth of the cartridge case. The water pressure generated by the punch when struck is used to push the primer out. After the primer is pushed out, the punch is not easy to remove from the cartridge case, making it inconvenient to use. Summary of the invention

[0003] The purpose of the utility model is to remove the primer quickly and without damage and to reuse it.

[0004] The technical solution of the utility model is: a press-in primer disassembly mold, comprising a pressure head 1, a mold body 2, a sealing ring 3, and a gasket 4; the mold body 2 is a tubular structure, the lower end hole of which is interference fit with the sealing ring 3, and the upper end hole is adapted to the pressure head 1; the inner hole of the sealing ring 3 is interference fit with the gasket 4.

[0005] The mold body 2 is a tubular structure, the inner diameter of which is adapted to the small diameter end of the pressure head 1 and has an interference fit with the outer diameter of the sealing ring 3 .

[0006] The sealing ring 3 is an annular structure, the outer diameter cone angle is 5° to 10°, and the inner diameter is interference fit with the gasket 4.

[0007] The sealing ring 3 is an annular structure and is made of rubber or silicone material.

[0008] The gasket 4 is an annular structure, and its inner hole diameter is 1mm to 3mm larger than the diameter of the primer.

[0009] The cross section of the pressure head 1 is a T-shaped structure.

[0010] The beneficial effects of the utility model are as follows: the utility model adopts a press-in primer disassembly mold, which can quickly and non-destructively remove the primer and can be reused. The utility model has a simple structure, is easy to operate, and does not damage the primer. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] like Figure 1 As shown, a mold for pressing and removing primers comprises a pressing head 1, a mold body 2, a sealing ring 3 and a gasket 4; the pressing head 1 slides in the mold body 2; the sealing ring 3, the mold body 2 and the gasket 4 are interference fit; the gasket 4 is installed into the end with a larger diameter of the sealing ring 3, and the other end is placed on the shell to be removed from the primer, and then inserted into the mold body 2, the mold body 2 is filled with water, the pressing head 1 is placed in the mold body 2, and the primer can be pushed out by quickly hitting the pressing head 1 with a hammer.

[0018] like Figure 2 As shown, the cross section of the pressure head 1 is a T-shaped structure.

[0019] like Figure 3 As shown, the sealing ring 3 is an annular structure, made of rubber or silicone material, with an outer diameter cone angle of 5° to 10°, and an inner diameter having an interference fit with the gasket 4.

[0020] like Figure 4 As shown, the gasket 4 is an annular structure, and its inner hole diameter is 1mm to 3mm larger than the primer diameter.

[0021] like Figure 5 As shown, the inner diameter of the mold body 2 is adapted to the small diameter end of the pressure head 1 and has an interference fit with the outer diameter of the sealing ring 3.

[0022] By adjusting the size of the mold sealing ring 3 and the gasket 4, the press-in primer of cartridge cases of various sizes can be disassembled.

[0023] The utility model is fixed in the mold body by the sealing ring 3 and Figure 1 Assemble the components. Use a hammer to quickly hit the pressure head 1 to push out the primer.
