Description
Przedmiotem wynalazku jest forma wtryskowa do wulkanizacji wyrobów gumowych, umozliwia¬ jaca otrzymywanie wlasciwego wyrobu przy mi¬ nimalnym nadmiarze mieszanki.The subject of the invention is an injection mold for vulcanization of rubber products, it enables how to get the right product with minimal excess of the mixture.
Stosowane dotychczas na agregatach wtrysko¬ wo-wulkanizacyjnyeh formy do wulkanizacji wy¬ robów gumowych skladaja sie z plyt z wykona¬ nymi na wewnetrznych plaszczyznach zaglebie¬ niami tworzacymi gniazda odpowiadajace rozmia¬ rom zadanego wyrobu.So far used on injection units vulcanization molds for vulcanization of the products rubber robots consist of boards with workmanship on the inner surfaces of the recess nests of the correct size a rom for a given product.
Na tych samych plaszczyznach plyt jest wyko¬ nana siec kanalów doprowadzajacych mieszanke gumowa od glównego kanalu wtryskowego do poszczególnych gniazd formy.There is a finish on the same plane of the plates There is a network of channels supplying the mixture rubber from the main injection channel to individual mold slots.
Caly zestaw plyt gniazdowych jest umieszczo¬ ny pomiedzy plytami grzejnymi. Na skutek takie¬ go ukladu, zwulkanizowaniu ulega mieszanka w gniazdach formy i w sieci kanalów rozprowadza¬ jacych lacznie z glównym kanalem wtryskowym, powodujac tworzenie sie bezuzytecznego odpadu, czestokroc przewyzszajacego ciezarem produko¬ wane wyroby.The entire set of socket plates is inserted between the hobs. As a result of such system, the mixture of w distributors in the mold cavities and in the channel network connections including the main injection channel, causing the formation of useless waste, often exceeding the production weight important products.
Przeplyw mieszanki gumowej przez dluga siec waskich, goracych kanalów rozprowadzajacych powoduje takze czeste podwulkanizowanie plyna¬ cej mieszanki, powodujac tym zwiekszenie wadli¬ wosci wulkanizowanych wyrobów.Flow of the rubber mixture through a long network narrow, hot distribution channels it also causes frequent scorching of the fluid more of the mixture, thereby increasing the defect value of vulcanized products.
Forma wtryskowa wedlug wynalazku skladaja¬ ca sie z plyt z wykonanymi na wewnetrznych plaszczyznach zaglebieniami tworzacymi gniazda, posiada plyte z kanalami rozprowadzajacymi mie¬ szanke gumowa, przy czym plyta ta jest termo¬ statowana oraz oddzielona od plyt gniazdowych plyta izolacyjna.The injection mold according to the invention is composed all with internal plates on surfaces with hollows forming nests, has a disc with distribution channels A rubber tube, the plate being thermo-electric static and separated from the socket plates insulation board.
Zaleta formy jest zmniejszenie do minimum ilosci mieszanki gumowej traconej w kanalach doplywowych.The advantage of the form is to reduce it to a minimum the amount of rubber compound lost in the channels tributaries.
Forma wedlug wynalazku jest przedstawiona w przykladzie wykonania na zalaczonym rysunku, na którym fig. 1 przedstawia forme w przekroju poprzecznym, zas fig. 2 widok z góry na otwarta czesciowo dolna polówke formy.The form according to the invention is shown in an example of execution in the attached drawing, in which fig. 1 shows the mold in section transversely, and fig. 2 an open view from above partially lower half of the form.
Przedstawiona na rysunku fig. 1 i 2 forma po¬ siada plyty gniazdowe 1 i 2 z wykonanymi na ich wewnetrznych plaszczyznach zaglebieniami tworzacymi gniazda 6 oraz plyty grzejne 9 i 10.The form of the form shown in FIGS. 1 and 2 socket plates 1 and 2 with their inner planes with dimples forming sockets 6 and heating plates 9 and 10.
Plyta 4 posiada siec kanalów 5, rozprowadzaja¬ cych wtryskiwana ustnikiem 7 mieszanke gumo¬ wa do zaglebien 6 wykonanych w plytach gniaz¬ dowych 1 i 2. Plyta termostatowana jest w tem¬ peraturze odpowiadajacej przeplywowi plastycz¬ nemu mieszanki, powodujac, ze material znajdu¬ jacy sie w glównych kanalach doplywowych 5 nie ulega zmianom chemicznym zachodzacym w procesie wulkanizacji. Material, zawarty w glów¬ nych kanalach doplywowych 5, jest w kazdym cyklu pracy wtryskarki przetlaczany do gniazd 6 i uzupelniany nowa porcja wtryskiwana przez urzadzenie slimakowe wtryskarki. 103 613103 613 3 4Disc 4 has a network of channels 5 for distribution injected with the mouthpiece 7 a mixture of rubber shaft for soils 6 made in socket plates 1 and 2. The hob is thermostated to temperature corresponding to plastic flow the mixture, causing the material to be found main inlet channels 5 does not undergo chemical changes taking place in vulcanization process. The material contained in the head 5 inlet channels are in each work cycle of the injection molding machine transferred to the sockets 6 and replenished with a new batch injected by injection molding machine screw device. 103 613 103 613 3 4
