    This invention relates to the field of
    the manufacture of products from ispolymer materials and intended for their heat treatment, in particular; vulcanization of rubber-like materials.
    Closest to the invention of the technical essence and the achieved result. is a device for the thermal treatment of products made of polymeric material, containing a metal mold and a heating system, having a burner, a metal heat-conducting chamber, a gas pipeline for heating the gas mold-5 direct combustion and an exhaust outlet. 0
    In the known device, the gas pipeline is a duct of considerable volume in which a mold is installed 20, while the heat transfer from the direct combustion gases goes to the mold through the chamber, which reduces the efficiency of the sump.
    The object of the invention is to increase the heating efficiency.
    This goal is achieved by the fact that in a device for heat treatment of polymer products a containing a metal press mold 30 and a heating system having a burner, a metal heat conducting chamber, a gas pipeline for heating the mold with direct combustion gases and exhaust the output, the heat-conducting chamber is made of a mold in contact with the surface with the formation of cavities along the outer surface boundaries, and the gas pipeline is made in the form of supply channels placed in the heat-conducting chamber, communicating through the holes in the cavities, and distribution channels located on the surface of the mold between the supply channels and communicating with the hollows and the exhaust outlet.
    The exhaust outlet is made in the form of a channel located in the body of the heat-conducting chamber.
    The mold is made in the form of an annular cage, and the heat-conducting chamber is in the form of two rings mounted on the cage with an annular gap serving as an exhaust outlet.
    The feed channels are made in the form of toroidal coils located along the ends of the cage.
    The feed channels are provided with nozzles to control the rate of gas circulation in them.
    FIG. 1 shows the proposed device with a plate-type mold; in fig. 2 is a top view mold; FIG. 3 shows a device with a mold in the form of an annular cage; FIG. 4 - the same, side view; in fig. 5 - supply channel in the form of a toroidal coil; in fig. 6 - burner, longitudinal section.
    The device for heat treatment of polymer products contains a metal mold that may have lower 1 and upper 2 plates (Fig. 1), and a heating system 3 that has a burner 3 and a metal heat-conducting chamber 4. Chamber D is made in contact with the surface of the mold, with the formation on the borders of the outer surface of its upper plate 2 cavities 5 and is equipped with a heat insulating jacket 6 of asbestos. The heating system also includes a gas pipeline for heating the mold with direct combustion gases generated during operation of the burner 3, and an exhaust outlet 7. The gas pipeline is designed as 4 supply channels 8 in the heat-conducting chamber, communicating through the holes 9 with cavities 5, and distribution channels 10 located on the mold surface between the supply channels 8 and communicating with the cavities 5 and the exhaust outlet 7. The exhaust outlet 7 is made in the form of a channel located in the body of the heat-conducting chamber 4. Top plate 2 of the press-f rmy has a rectangular shape, made of steel or aluminum alloy and is embedded in a thermally conductive boiling chamber 4. The supply channels 8 are formed by ceramic tubes and the holes 9 are arranged with gaps (Preference titelno ravnmi) along the pipes and are arranged so that the nozzles are. an exact size for supplying hot gas supplied from the burner 3 to the upper plate 2 of the mold. For the formation of cavities 5 on the top plate 2 there are bevels 11. Distribution channels 10 can be cut through on the surface of the top plate 2 (Fig. 2). On the bottom plate 1 there is a heat insulating cushion 12. N The mold can be made in the form of an annular casing 13 made of aluminum alloy, and the heat-conducting chamber can be made in the form of two rings 14 mounted on the casing 13 from each other with an annular gap 15, serving as an exhaust outlet. In this embodiment, the device distribution channels 16 are made in the form of toroidal coils located on the ends of the casing 13 and providing gas in them, for adjusting the speed of which the coils have tangential inlet sections 17 connected to the inlet pipe 18 per, and located on their internal diameter of the hole 19 for supplying gas to the holder. The annular gaps 20 1 between the ferrule 13 and the rings 14 have distribution channels. Channels 16 may be stainless steel. One common or two individual burners can be used to supply hot gas to both turns. The inlet sections 17 are provided with nozzles to control the rate of gas circulation in the channels 16. A mold of this type is used in the processing of products such as tires of pneumatic tires, in their manufacture or repair. In this case, it is supplied with a pneumatic mandrel (not shown). The burner 3 comprises a chamber 22 coaxially mounted in the housing 21 for supplying air for combustion and a chamber 23 for evacuating hot combustion gases, a burner nozzle 24 arranged between them, a pipe 25 for supplying hot gas, a perforated distribution wall 26 and a box 27 for supplying air for mixing with combustion gases. At one end of the chamber 25, the burner nozzle 24 is mounted, and the other end is open to the atmosphere. The chamber 23 has on the side wall circumferential through holes 28 and is mounted relative to the burner nozzle 24 with an annular gap 29 for the passage of air to the cooling of the nozzle 24. The holes 28 can be made with an increase in the flow area to the outlet end of the chamber 23. 1 The burner can be different in design, but must be workable in an air-gas system, must provide good quality combustion, stable flame in a confined space (supply channels) and a given treatment temperature of the object to be as silent as possible. The device may have means for recirculating gases through the burner and heat exchanger. The device works as follows. Combustible gas, such as natural gas, is supplied through pipe 25 to a burner nozzle 24, where it is burned in air that is sucked into chamber 22. Formed 11
    The combustion gases exit the nozzle 2A through the chamber 23, where they mix with the air coming from the box 27 through the partition 26, and then enter the feed channels 8 or 16. From the latter, the heated gases are fed through the holes 9 or 19 to the mold surface to the plate 2 or the yoke 13, through the channels 10 or 20 are distributed over the surface of the mold, ensuring its uniform heating, and are discharged through the exhaust codes 7 or 15.
    The specified temperature distribution on the surface of the mold - a product can be achieved by positioning, dimensions, and placing holes 9 and 19 in channels 8, 16, selecting the material of the desired thermal conductivity for plate 2 or the sleeve 13 and the dimensions of channels 10 or 20.
    When the mold is heated, the product 30 is heat treated,
    D98616
    found in the mold cavity, for example, from uncured natural or synthetic rubber.
    The gases entering through the pipe 18 and the nozzles of the inlet sections 17 into the channels 16 (in the form of toroidal turns) begin to circulate in them, with some of them leaving through the holes 19 and filled with heated gases again supplied by the burner 3,
    In the proposed device, effective and legitimate heating of the mold and, consequently, of the product to be processed is provided, because its design allows the supply of heat energy from the combustion of the primary energy source directly to the element that transfers heat to the product.
