Description
Vynález se týká zařízení pro Ohřev trysky a aáetavce trysky strojů pro lití kovů pod tlakem s teplou lisovací koaoosu.BACKGROUND OF THE INVENTION The present invention relates to an apparatus for heating a nozzle and a nozzle of a die-casting machine with a hot pressing coaoose.
Jsou známy teplé lisovací keaery licích strojů, které jseu podstatnou Čáeií svého tělesa lisovací keaery ponořeny ée roztaveného kovu v kelímku pece a jseu jí· vyhřívány. Ze spodní části teplé lisevací kemory vystupuje směrem nahoru stoupací kenál, vytvořený v tělese lisevecí keaery, ne který navazuje nástavec trysky s tryskeu, ústící de dutiny licí foray. Herní část stoupaeího kanálu, jakéž i nástavec trysky s tryskeu še nachhoeeí nad hledineu reztsvenéhe kávu v kelíaku pece a jseu ochlazovány skalní atmosférou. Toto ochlazování má nepříznivý vliv ne kvalitu procházejícího roztaveného kovu a tím i kvalitu odlitku e ne životnest nástavce trysky a trysky. Aby se zabráiile echlazevání těchte čássí, je jia třeba dodávat teple. To se dedává větlinou plynovými hořáky, jejichž plaaeny jseu nasměrovány ne vyhhívané čtássi.There are known hot die keaers of casting machines which are immersed in the furnace crucible and are heated by a substantial part of their die die body. A rising kenal formed in the die keaer body extends from the bottom of the hot die chamber, which is not connected to the nozzle extension with the nozzle leading to the die cavity. The gaming part of the ascending channel as well as the nozzle nozzle with the nozzle is located above the viewpoint of the coffee in the baking furnace and is cooled by a rocky atmosphere. This cooling has an adverse effect on the quality of the molten metal passing through and thus on the quality of the casting and on the service life of the nozzle extension and nozzle. In order to prevent these parts from being chilled, it is necessary to supply warmth. This is inherited by most gas burners whose flames are directed to the heated partitions.
Tento způsob je ale nevýhedný v tea, že vyžaduje veddejěí samoosatný zdrej energie plyn a že se neddeííí rovnoměrného rozložení teplety následkem místního ehřevu a omezené tepelné , vodivosH vyseče legovaného maaeeiálu, ze kteréhe je tryska a nástavec trysky vyroben.However, this method is inconvenient in that it requires a side-by-side self-sowing energy of gas and that the uniform heat distribution due to local heating and the limited thermal conductivity of the chopped alloy material from which the nozzle and nozzle extension is made do not divide.
Lepšího rezležení teplet se desáhne použitím elektrického ehřevu, kdy vyhřívané části jseu opa třeny elektrický vinutía. Po třeba vedlejšího zdroje energie a regulačního zařízení k udržování rovnoměrné teploty v celé licí soustavě však tía odstraněna není.A better heating of the heat is achieved by the use of electric heating, wherein the heated parts are provided with electrical windings. However, the need for a secondary power source and control device to maintain a uniform temperature throughout the casting system is not removed.
Výše uvedené nevýhody snižuje na minimum zařízení pro ohřev trysky a nástavce trysky podle vynálezu, jehož podstata spočívá v tea, že kolem nástavce trysky s tryskal je těsně uspořádán plášt o dutina, ohraničená pláštěm a nástavcem trysky je propojena se soustavou kanálů, vytvořených v tělese teplé keaery podél stoup^ího kanálu, přičeaž dutina a kanály jsou vyplněny teplonosnou látkou. Dále je výhodné opatřit plášl tepelnou izolací a propooit dutinu s atmosférou přes expanzní nádobu.The above-mentioned disadvantages are minimized by the nozzle heating device and the nozzle extension according to the invention, which is characterized in that a casing about a cavity is tightly arranged around the nozzle extension with the nozzle bounded by the jacket and nozzle extension connected to a plurality of ducts formed in the body. keaery along the ascending channel, the cavity and channels being filled with a heat transfer substance. Furthermore, it is advantageous to provide the jacket with thermal insulation and to propooit the cavity with the atmosphere through the expansion vessel.
Zařízení pro ohřev trysky a nástavce trysky pedle vynálezu se desáhne vyrovnané teplety v celéa licía agregátu licího stroje, což se příznivě projeví ve zvýšené životnessi licího agregátu a lepší kveXltS,odlitků, přičeaž se ušeeří přídavný zdroj energie a složité regulační zařízení.The device for heating the nozzle and nozzle extensions of the present invention achieves equal heats throughout the casting machine of the casting machine, which results in increased life of the casting machine and improved quartz casts while saving additional power and complex control equipment.
Na přiloženém výkresu je zobrazen v řezu příklad provedení zařízení pro ohřev trysky a nástavce trysky podle vynálezu.In the accompanying drawing, an exemplary embodiment of a nozzle heating device and a nozzle extension according to the invention is shown in cross-section.
Jak vyplývá z obr., je v tavenině 2 kelíaku 1 pece ponořena podstatná část tělesa 3 licí keaery a horní část tělesa 2 licí keaery, do které je vsazen nástavec 4 trysky s tryskou ž, se nachházjí nad hledineu taveniny 2 v kelíaku 1 pece. V tělese 3 licí kemory je vytvořen stoupací kanál f, spaeující tepleu lisevací komoru 7, ve které je posuvně uložen vytl^ť^č^ovac:ř píst 12« s průtlečrýta kutálen 8 nástavce 4 trysky a tryskou 2 , která úattí de duuiny licí formy. Podél stoup^ího kanálu 6 je v tělese 3 licí keaery vytvořena soustava kanálů 2» 2»'které jseu propojeny speovaacial kanály J4, 14' s dutineu 10, vytvořenou aezl pláštěm 11 a nástavcem 4 trysky. Pláší 11 , je upevněn a utěsněn na nástavci 4 trysky a na svém vnnjjím povrchu je opatřen tepelnou izolací Н» Dutina 10 je dále propojena spojovacím kanálem 14 přes expanzní nádebu 12 s skelní atmosférou. Soustava kanálů 2, 2 > dutina 10, expanzní nádoba 12 a spojovací kanály 14, Ц*, H^seu vyplaěny teplar^nou látkou.As can be seen from the figure, a substantial part of the casting body 3 is submerged in the furnace melter 1 and the upper part of the casting body 2 into which the nozzle nozzle 4 is inserted is located above the viewpoint of the melt 2 in the furnace 1. In the casting body 3 there is formed a riser channel f, which heats the heat of the pressing chamber 7, in which a displacement piston 12 is disposed in the nozzle extension 4 and a nozzle 2 which in turn casts the duo of the nozzle. forms. Along the rising duct 6, a system of ducts 2, 2 '' is formed in the casting body 3, which is connected by the spacing ducts 14, 14 'to the cavity 10 formed by the housing 11 and the nozzle extension 4. The casing 11 is fastened and sealed to the nozzle extension 4 and is provided with thermal insulation 10 on its outer surface. The cavity 10 is further connected by a connecting channel 14 via an expansion vessel 12 to a glass atmosphere. The channel assembly 2, 2, the cavity 10, the expansion vessel 12 and the connection channels 14, 14, 11 are flushed with the thermal substance.
