The invention relates to foundry and can be used in injection molding machines.

The uncooled extrusion chamber is known, made in the form of a thick-walled cylinder with a casting window at the rear end.

A cooled extrusion chamber is known, having a jacket fitted on the pipe with cooling paths between them.

The disadvantages of this design are: the difficulty of providing a seal between the pipe and the casing at the front end of the chamber in the area of the filling window; the difficulty of assembling the pipe and the casing among themselves, it is necessary to heat the casing or cool the pipe or to cold-press one into the other; the impossibility of multiple use of the casing which during welding is welded to the pipe due to the formation of corrosion on the adjacent surface and cooling and rust and heat. nakigi at its boiling v, impurities during the circulation of refrigerant through them

The purpose of the invention is to simplify assembly and improve maintainability.

The chain is achieved by pouring under pressure with, in the pressing chamber of the machine. 8, which surrounds the coarse with the casting window and the casing surrounding it with channels, cool the depot on the inner surface connected with the holes for supplying and discharging the outer surface of the pipe between the end and the pouring window and opposite the pouring longitudinal groove. The vy / ne lz two halves placed in an annular recess with a gap between them and there are two longitudinal grooves on the outer surface in the zone of the joining of the joints of the chamber. The chamber is equipped with two crust-shaped lids with gaskets. layouts placed in the longitudinal to the icons of dryness at the same time from the belief g for the approach and removal of the refrigerant

The jd of pressing is different from the well-known that on the outer pipe about the amphibious pipe and the filling window there is an annular y-hole, opposite the filling window, a longitudinal groove, koh /: w is made two of them are placed in a ring with a gap and have two longitudinal The KII channel on the outer surface in the zone of connection is the Bvii field; the chamber is equipped with two double-sided covers with rock sealer V.

The pressing chamber placed in the nest of the bed 1 of the casting machine forms a casing in the form of halves 3 mounted on the pipe 2 and placed with a gap 4 between their edges in the annular recess of the pipe 2 formed between the front end 5 of the chamber and its filling window 6 ha of the inner surface of the halves 3 There are grooves 7 of variable width or depth that are necessary for uniform cooling of the pressing chamber.
