Abstract

Z připraveného modelu sa vyberie trojdielna holeňová časť kopyta, vnútorná časť zvršku po; vybratí trojdielnej holeňovej časti sa natrie epoxidovou živicou so zosieťovadlom. Vloží sa vybratá trojdielna časť holené do zvršku spát a posúvaním epoxidovou živicou natřeného zvršku po naseparovanej trojdielnej časti holene sa vytvaruje do požadovaného tvaru.A three-part is selected from the prepared model the shin part of the hoof, the inner part upper after; removing the three-part shin section with epoxy resin with crosslinker. The removed three-part shin is inserted sleep in the upper and move the epoxy resin-coated upper after separation the three part shin is shaped to the desired shape.

Description

Vynález sa týká .nakrčenia základných modelov k výrobě foriem nakrčenej odlievanej obuvi.The invention relates to the crimping of basic models for producing molds of crinkled cast shoes.

Pri výrobě odlievanej obuvi z pást PVC potřebný počet foriem sa připravuje galvanoplastickou cestou — nanášením vrstvy niklu na postriebrený povrch modelu. Zo základného modelu připraveného modelářským sposobom sa připraví matečná forma, v ktorej sa vyhotovia odlievaním násobné modely potřebné k výrobě výrobnýeh foriem známým technologickým postupom.In the production of cast footwear from PVC pastes, the required number of molds is prepared by a galvanoplastic method - by applying a layer of nickel on the silver-plated surface of the model. From the basic model prepared by the modeling process, a parent mold is prepared in which the multiple models necessary to produce the production molds by a known technological process are produced by casting.

Základný model pozostáva z voskovej časti kopyta, trojdielnej holeňovej časti kopyta pripravenej z tvrdej polyuretánovej pěny a napnutého zvršku, vyhotoveného z usne, alebo syntetického vrchového materiálu, ktorý tesne obaluje povrch voskovej časti kopyta a trojdielnej polyuretánovej holeňovej časti kopyta. Vzhfad povrchu připraveného Základného modelu určuje vzhfad hotového výrobku — odlievanej obuvi. Takto připravené základné modely k výrobě foriem odlievanej obuvi s hladkým, popřípadě dezénovaným povrchom umožňujú výrobu odlievanej obuvi s viac-menej imitovaným vzhfatdorn usne.The basic model consists of the waxy part of the hoof, a three-part hoof part made of rigid polyurethane foam and a stretched upper made of leather, or a synthetic top material that tightly surrounds the waxy part of the hoof and the three-part polyurethane shin part. The appearance of the surface of the prepared Base Model determines the appearance of the finished product - the molded footwear. The basic models prepared in this way for the production of molds of cast shoes with a smooth or embossed surface allow the production of molded shoes with more or less imitated leather.

Věrnější vzhfad imitácie usne u odlievanej obuvi dává jej nakrčenie v časti holene, čo umožňuje spůsob nakrčenia základných modelov k výrobě foriem odlievanej obuviA more faithful appearance of imitation leather in cast shoes gives it a wrinkle in the part of the tibia, which allows the base models to wrinkle to produce molds of cast shoes

PREDMETSUBJECT SpQsob nakrčenia základných modelov k výrobě foriem nakrčenej odlievanej obuvi vyznačujúci sa tým, že z napnutého zvršku (1) modelu sa vyberie trojdielna holeňová časť (2) kopyta, naseparuje sa roztokom vosku, vnútorná časť napnutého zvršku (lj po vybratí trojdielnej holeňovej časti (2) vyznačujúci sa tým, že z napnutého zvršku 1 modelu sa vyberie trojdielna holeňová časť 2 kopyta, naseparuje sa roztokom vosku, vosková časť 4 kopyta sa ponechá vo zvršku 1, vnútorná časť napnutého zvršku 1 po vybratí trojdielnej holeňovej časti 2 kopyta sa natrie epoxidovou živicou 3 so zosieťujúcim prostriedkom, vloží sa spSť naseparovaná trojdielna holeňová časť 2 kopyta a posúvaním epoxidovou živicou natrenej holeňovej časti zvršku 1 po naseparovanej trojdielnej holeňovej časti 2 kopyta sa vytvaruje do požadovaného nakrčenia.BACKGROUND OF THE INVENTION Basic models for making molds of crinkled molded footwear, characterized in that a three-part shin part (2) of the last is removed from the stretched upper (1) of the hoof, separated by a wax solution, the inner part of the stretched upper (1j). ) characterized in that a three-part shin part 2 of the hoof is removed from the stretched upper 1 of the model, separated by a wax solution, the wax part 4 of the hoof is left in the upper 1, the inner part of the stretched upper 1 is removed with epoxy resin 3 with the crosslinking agent, the re-assembled three-part shin portion 2 of the hoof is inserted and by shifting the epoxy resin-coated shin portion of the upper 1 over the separated three-part shin portion 2 of the hoof to form the desired wrinkle. Nátěr epoxidovej živice 3 před jej zosietením umožňuje posúvať holeňovú časť zvršku 1 po trojdielnej holeňovej časti 2 kopyta, i keď zvršok 1 celé kopyto tesne obopína. Po zosietení působí nátěr epoxídovej živice 3 ako výstuž nakrčenej častí, zabraňuje jej ďalšej nežiadúcej deformácii a tým i popraskaniu striebornej vrstvy viplyvom hydrostatického tlaku elektrolytu v galvanickej váni. Umožňuje však vybrat trojdielnu holeňovú časť 2 kopyta po nanesení niklovej škrupiny v galvanickej váni bez jej porušenia. Vosková časť 4 kopyta sa z niklovej škrupiny nahriatim vytaví.The coating of epoxy resin 3 prior to its crosslinking allows the shin portion of the upper 1 to move along the three-part shin portion 2 of the last, even though the upper 1 is tightly wrapped around the last. After crosslinking, the coating of the epoxy resin 3 acts as a reinforcement of the crimped parts, preventing further undesirable deformation thereof and thus the cracking of the silver layer due to the hydrostatic pressure of the electrolyte in the galvanic vessel. However, it allows to remove the three-part shin part 2 of the hoof after the application of the nickel shell in the galvanic tank without breaking it. The wax portion 4 of the last is melted from the nickel shell by heating. Na výkrese je na obr. 1 praktické vyhotovenie nakrčenia modelu podfa vynálezu v řeze.In the drawing, FIG. 1 shows a cross-sectional view of a crouching model of the present invention. vynalezu kopyta sa natrie epoxidovou živicou (3) so zosieťujúcim prostriedkom, vloží sa spát voskom naseparovaná trojdielna holeňová část (2) kopyta a posúvaním epoxidovou živicou (3) natrenej holeňovej časti zvršku jlj po trojdielnej holeňovej časti (2) kopyta sa vytvaruje do požadovaného nakrčenia.of the inventive hoof is coated with an epoxy resin (3) with a crosslinking agent, inserted into a wax-separated three-part shin portion (2) of the last and sliding the epoxy resin (3) of the painted shin portion of the upper jlj over the three-part shin portion. .
