Abstract
The invention relates to weapons engineering and concerns hunting and sporting plastic cartridge cases. The aim of the invention is to improve the ballistic properties and resistance of the article and to reduce production costs. The inventive cartridge case is embodied in the form of thin-walled cylinder provided with an external cylindrical wall and an internal wall embodied in the form of three conical sections whose extension and taper are successively increase away from the bottom of the cylinder, said bottom being provided with a percussion cap hole. Said plastic cartridge case comprises a thin-walled diaphragm which divides the cavity of the cylinder from the cavity of the percussion cap. The thickness of said diaphragm ranges from 0.2 to 0.5 mm. The inventive device for producing said plastic cartridge case comprises a casting mould embodied in the form of a matrix forming the outer surface of the cartridge case, a semimartix provided with a filler hole and forming the bottom of the cylinder, and a core male forming the inner surface of the cartridge case. Said semimatrix is provided with a hollow finger forming a closed percussion cap hole and forming an angular gating nozzle with the core male.
Description
Present invention relates in general to a kind of miniweapon technology, relate in particular to hunting cartridges and shooting sports bullet with plastic casing.
The existing plastic ball shell that is used for shooting sports bullet and hunting cartridges has the thin-walled cup bodily form, and its outer surface is cylindrical and has the opening that is used for fuse (as the BP UK1161422 that published in 1969, its classification number is F42B5/30) in the bottom.
Known to the prior art, the device that is used to make this plastic ball shell is by mould and have the allocation block (distribution block) of casting opening and form.
The major defect of existing housing is exactly that structural strength is lower, and this makes that housing can be broken in shooting course.The geometry and the process technology thereof of the inner surface of this housing can not provide structural strength because of casting flaw.
These defectives are not that existing plastic ball shell is exclusive, the inner surface of these existing plastic ball shells comprises three tapering parts, the tapering of these three tapering parts and length begin to increase (the utility model patent RU11882 that authorizes of Russia in 1999 for example from the bottom, classification number is F42B5/30, aspect similitude, this utility model is immediate with the present invention).The device that is used to make this housing is described in the prior art.
The defective of existing housing is, makes the ammunition particulate be penetrated into can to produce in the fuse fault aspect igniting and the expansion of cartridge parameter in the process of filling cartridge.
The defective that is used to make the device of this housing is that straight pin is arranged on the stamping machine, this be arranged in rapidoprint is cast in the process in the container can cause off-axis, this can cause geometry deformation and structural strength to reduce such situation again.
Purpose of the present invention is exactly to improve the ballistics data and the structural strength of this product with lower cost price.
This technical problem is solved by plastic ball shell is provided, it is cup-shaped that this shell case has thin-walled, has cylindrical outer surface, its inner surface comprises three tapering parts, the tapering of these three tapering parts and length begin from the bottom to increase, this bottom has the opening that is used for fuse, and film cuts off the shell case part and the part that is used to install fuse is separated.The range of choice of the thickness that this film cuts off is 0.2-0.5mm.
The device that is used to make plastic ball shell comprises: a mould, this mould are a container that is used to form the outer surface of shell case; One and half sheet containers, this half sheet container has the taper casting gate and is used to form cup-shaped bottom; And jumper bar that forms the shell case inner surface.On this half sheet container a cylinder type hollow pin is arranged, this hollow pins forms the fuse opening of a sealing.This cylinder type hollow pin forms ring gate with jumper bar.
Shown in Figure 1 is the longitudinal sectional view of this shell case, and shown in Fig. 2 is the cutaway view of making the device of this plastic ball shell.
This shell case shape resembles cup 1, and its inner surface comprises three sections tapering parts.
The part that cup (shell case) part and being used to is installed fuse is cut off 7 by film and is separated.
The device that is used to make plastic ball shell comprises container 8, half sheet containers 9 and jumper bar 10.The straight pin 11 that is formed on the half sheet container forms the fuse opening that seals.Ring gate 12 is between the surface of the surface of straight pin 11 and jumper bar 10.
The manufacture process of this shell case is as follows:
Plastic raw materials is transported to the cylinder open of half sheet container 9 from allocation block (distribution block) (not shown), with after straight pin 11 and ring gate 12 be penetrated into and in the mould its space be full of equably and make outward appearance not produce flaw.After final shell case is taken out, thereby partition between the remaining shell case part is partly removed in unnecessary casting from mould.
Shell case according to this method manufacturing has following advantage.
This shell case has improved structural strength properties.Shell case is merotomized: fuse part and combustion parts make shell case improve the ballistics characteristic and make ignition procedures be improved owing to having eliminated the influence to the combustion intensity of fuse of ammunition filling effect.
According to test, the range of choice of the thickness that this film cuts off is 0.2-0.5mm.Described shell case has improved structural strength properties, has reduced manufacturing cost, has shortened the filling cartridge parameter of ammunition charge pressure and the spreading range of emission rate.
Claims (2)
1. plastic ball shell, has a kind of thin-walled cup shape, this cup has cylindrical outer surface, and inner surface has three sections tapering parts, the length of these three sections tapering parts and tapering begin to increase from the bottom of shell case, this bottom has the opening that is used for fuse, it is characterized in that, thickness is that the film of 0.2-0.5 millimeter cuts off the shell case part and the part that is used to install fuse is separated.
2. be used to make the device of this plastic ball shell, this device comprises: mould, and this mould is for forming the container of shell case outer surface; Half sheet container has taper casting opening, and this half sheet container forms the bottom of cup; And jumper bar, be used to form the inner surface of shell case, it is characterized in that, on the hollow pin of half sheet container, make, form the fuse opening of sealing, and form ring gate with jumper bar.
