Abstract
The present invention generally relates to small arms technology and, more particularly, is concerned with hunting and sporting cartridges having plastic cases. <??>The objective of the invention is increasing of the ballistic data and structural strength of the product with low price of its manufacturing: <??>This problem is solved by supplying of the plastic cartridge case in the shape of thin-walled cup of cylindrical external surface and internal surface comprising three conical portions of length and taper increasing from the bottom having the opening for the primer with a dam-diaphragm separating the cartridge case part and the part for the primer installation. The dam-diaphragm thickness is selected within the range of 0,2 - 0,5 mm. <??>The device for manufacturing of the plastic cartridge case contains a mold performed of a matrix forming the external surface of the cartridge case, a halfmatrix with conical casting opening which forms the cup bottom and a punch forming the internal surface of the cartridge case. On the halfmatrix is a cylindrical hollow pin forming a closed primer opening. The cylindrical hollow pin together with the punch form a ring sprue.

Patents Act 1990 VERIFICATION OF TRANSLATION PATENT APPLICATION NO. 2002304212 (corresponding to PCT/RU02/00232) I, (name) Sukhova Galina of: (address) str.4-5, bild. 6, Shluzovaya Naberezhnaya, Moscow 115114, Russia am the translator of the documents attached hereto and state that the following is a true translation thereof to the best of my knowledge and belief.
Signed: CI- Dated: 2ao-3 Middletons 4/27/2007 4:38:35 PM PAGE 6/015 Fax Server Plastic cartridge case and device for the production thereof Field of the invention The present invention generally relates to small arms technology and, more particularly, is concerned with hunting and sporting cartridges with plastic cases.
Background There are known plastic cases for sporting and hunting cartridges in the shape of a thin-walled cup of cylindrical external surface and with opening at the bottom for primer (Patent UK 1161422, F 42B 5/30, published in 1969).
Known from this source, a device for manufacturing of plastic cartridge case is composed of a mold and a distribution block with casting openings.
The main drawback of the existing case is its low structural strength the case breaks down during shooting. Internal surface geometry of the case and its processing technique do not provide structural strength because of casting defects.
These defects are not peculiar to the existing plastic cartridge case with internal surface comprising three conical portions of length and taper increasing from the bottom (Certificate for useful model RU 11882, F 42 B 5/30, 1999 closest analog). The device for manufacturing the case is described in this source.
The drawback of the existing case is penetration of powder corpuscles into the primer during the filling of the cartridge resulting in failure of ignition and cartridge parameters spread.
The drawback of the device for manufacturing of the case is that the cylindrical pin is arranged on the punch that leads to declination from axis during the casting of matrix by working mass resulting in the case geometry failure and reduction.of structural strength.
An objective of the invention is increasing of the ballistic data and structural strength of the product with low price of its manufacturing.
Reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that this prior art is common general knowledge or forms part of the common general knowledge in Australia or any other country.

COMS ID No: SBMI-07157469 Received by IP Australia: Time 16:45 Date 2007-04-27 Middletons 4/27/2007 4:38:35 PM PAGE 7/015 Fax Server 2 Summary of the invention The abovementioned problem is addressed by supplying a plastic cartridge case in the shape of a thin-walled cup of cylindrical external surface having an internal surface comprising three conical portions of length and taper increasing from the bottom having the opening for the primer with a dam-diaphragm separating the cartridge case part and the part for the primer installation, in which the dam-diaphragm thickness is selected within the range of 0,2 mm.
The device for manufacture of the defined plastic cartridge case includes a mold comprising a matrix forming the external surface of the cartridge case, a halfinatrix with a conical casting opening which forms the cup bottom and a punch forming the cartridge case internal surface of three conical portions of length and taper increasing from the bottom, the halfmatrix having thereon a cylindrical hollow pin forming a closed primer opening, the cylindrical hollow pin together with the punch forming a ring sprue.
Detailed description of the invention The longitudinal section of the cartridge case is shown on picture 1 and section of the device for manufacturing of the plastic cartridge case is shown on picture 2.
The cartridge case is shaped as the cup 1 with internal surface 2 comprising three conical portions.
At the bottom 3 is the primer opening 4. Inside of the cup (around the opening 4) there is a compensation groove 5. A recess 6 performed concentrically with the opening 4 on the outside surface of the bottom 3.
The cup (cartridge case) part and part for the primer installation is divided by the damdiaphragm 7.
The device for manufacturing of the defined plastic cartridge case consists of the matrix 8, the balfmatrix 9 and the punch 10 forming the cartridge case internal surface of three conical portions of length and taper increasing from the bottom.
Made on the halfmatrix 9, the cylindrical hollow pin 11 forms the closed primer opening. The ring sprue 12 is between the surface of the pin 11 and the surface of the punch The manufacturing process of the cartridge case is as follows: The plastic mass is supplied from the distribution block (not shown on the picture) into the cylindrical opening of the halfmatrix 9, then through the pin 11 and the ring sprue 12 penetrates into the mold filling full its space uniformly excluding appearance of defects.
After taking the finished cartridge case out of the mold, unnecessary part of pour is removed leaving the dam of 0,2 -0,5 mm thickness between the parts of the cartridge case.
The cartridge case manufactured according to this method has the following advantages.
The cartridge case has improved structural strength characteristics. Division of the cartridge case parts: the primer part and the combustion part results in improvement of ballistic characteristics of the cartridge case due to exclusion of powder charge effect on burning intensity of the primer and ignition process improvement.
