Description
Przedmiotem wynalazku jest kokila metalowa stosowana w odlewnictwie do wytwarzania odlewów.The subject of the invention is a metal die used in foundry for the production of castings.
Znane sa, na przyklad z publikacji ksiazkowej Górny Z., Chabowski W., Zakrzewski J., Bruzda K. - „Odle¬ wanie kokilowe stopów zelaza", kokile wyposazone w plyte chlodzaca, przymocowana do zewnetrznych scianek kokili najczesciej za pomoca srub. W celu zmniejszenia oporów przeplywu ciepla powierzchnie kokili i ukladu chlodzenia sa szlifowane. Miedzy te powierzchnie wprowadza sie równiez przekladki z blachy aluminiowej lub z proszku aluminiowego, albo z pasty o skladzie zblizonym do skladu smaru lancuchowego.They are known, for example, from the book publications by Górny Z., Chabowski W., Zakrzewski J., Bruzda K. - "Odle¬ iron alloy die cutters ", molds equipped with a cooling plate, attached to the outer walls molds, most often with screws. In order to reduce the resistance to heat flow, the die surfaces and the system cooling are ground. Between these surfaces are also placed spacers made of aluminum sheet or from aluminum powder or from a paste with a composition similar to that of chain lubricant.
Zapewnienie dobrego styku elementów chlodzacych z kokila jest trudne do uzyskania.It is difficult to achieve good contact between the cooling elements and the die.
Istota wynalazku jest dodatkowe wyposazenie kokili w zbiornik szczelinowy, ograniczony z jednej strony powierzchnia kokili, a z drugiej strony obudowa chlodzaca i ramka dystansowa. Zbiornik wypelniony jest metalem lub stopem metali o dobrej przewodnosci cieplnej, zblizonej objetosci wlasciwej wstanie cieklym i stalym oraz o niskiej temperaturze topnienia w granicach od 50 do 150°C.The essence of the invention is the additional equipment of the die with a slotted tank, limited on one side the mold surface, and on the other hand, the cooling housing and the spacer. The tank is full a metal or a metal alloy with good thermal conductivity, approximately the volume in the liquid state and steady and with a low melting point between 50 and 150 ° C.
Zaleta kokili wedlug wynalazku jest skutecznosc chlodzenia porównywalna z bezposrednim chlodzeniem wodnym, przy równoczesnym zapobiezeniu przedostania sie wody chlodzacej do cieklego metalu w przypadku pekniecia kokili.The die according to the invention has the advantage of a cooling efficiency comparable to that of direct cooling water, while preventing the ingress of cooling water into the liquid metal in the case of cracks in the mold.
Kokila wedlug wynalazku jest blizej objasniona na rysunku, który przedstawia przekrój pionowy zestawu kokili z obudowa chlodzaca.The die according to the invention is explained in more detail in the drawing which shows a vertical section of the assembly die with cooling housing.
Miedzy plyta chlodzaca 1 a kokila 2 wstawia sie ramke dystansowa 3, która ustala miedzy ich powierzchniami szczeline grubosci okolo 0,5-2,0 mm oraz spelnia role uszczelnienia zestawu. Ugory do szczeliny wykonuje sie przelew kontrolny 5 sluzacy do sprawdzenia poziomu metalu w szczelinie oraz do wyrównania róznic dylatacyjnych. Do utworzonego w ten sposób zbiornika szczelinowego wprowadza sie metal, lub stop metali tworzacy warstwe posrednia 4.Between the cooling plate 1 and die 2 a spacer frame 3 is inserted, which establishes between their with a gap of about 0.5-2.0 mm thick and acts as a seal for the set. Fallow to of the slot, a control overflow 5 is made to check the level of metal in the slot and to compensation of expansion differences. Metal is introduced into the slotted tank created in this way, or metal alloy forming the intermediate layer 4.
Uzyty w tym celu metal lub stop metali, na przyklad stop Wooda o skladzie: bizmut- 50% wagowych, olów-25% wagowych, cyna-15% wagowych, kadm-10% wagowych, musi posiadac niska temperature topnienia w granicach od 50-150°C, dobra przewodnosc cieplna i zblizona objetosc wlasciwa wstanie stalym i cieklym.2 87922 W czasie gdy kokila 2 nie pracuje, a wiec jest zimna, warstwa posrednia 4 jest zakrzepnieta. Po wypelnieniu kokili 2 roztopionym metalem nagrzewa sie ona i powoduje roztopienie warstwy posredniej 4, która dokladnie wypelnia szczeline i ulatwia wymiane ciepla miedzy powierzchniami kokili 2 i ukladu chlodzenia 1. Powierz¬ chnie kokili 2 i ukladu chlodzenia 1 nie wymagaja szlifowania.Used for this purpose metal or metal alloy, for example Wood's alloy with the composition: bismuth - 50% by weight, Lead-25 wt.%, Tin-15 wt.%, Cadmium-10 wt.%, must have a low temperature melting range from 50-150 ° C, good thermal conductivity and approximate volume in solid state and liquid 2 87922 By the time the die 2 is not running and therefore cold, the intermediate layer 4 is solidified. After filling the mold 2 with the molten metal heats up and causes the intermediate layer 4 to melt, which is completely fills the gap and facilitates heat exchange between the surfaces of the die 2 and the cooling system 1. Air drills die 2 and cooling system 1 do not require grinding.
