Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania artykułów, sposób wytwarzania form wtryskowych, forma wtryskowa i artykuł z zaczepem typu rzep na ściance bocznej. Sposób wytwarzania form wtryskowych do wytwarzania artykułów z zaczepem typu rzep, zawierających podstawę (101) i ścianki boczne (102), znamienny tym, że: przygotowuje się dwie części (120) formy, pomiędzy którymi po zamknięciu formy pozostaje przestrzeń wyznaczająca kształt podstawy (101) i ścianek bocznych (102) artykułu, przy czym pierwsza część formy stanowi stempel, a druga część (120) formy stanowi matrycę z gniazdem, przy czym w drugiej części (120) formy w miejscu odpowiadającym położeniu ścianki bocznej (120) formowanego artykułu kształtuje się przelotowy otwór zamykany płytą, w którym od strony pierwszej części formy umieszcza się pakiet (122) przyległych do siebie podłużnych blach (123), którego wymiary obwodu są równe wymiarom obwodu otworu (121), przy czym w każdej z blach (123) na jej głównych powierzchniach (124, 125) wykonuje się szereg wyżłobień (126, 127) formujących haczyki (103) nachylone pod kątem (α) w zakresie od 10 do 45 stopni, które rozpoczynają się od pierwszej podłużnej krawędzi blachy, która skierowana jest w kierunku pierwszej części formy i przebiegają torem haczykowatym w kierunku płyty zamykającej otwór (121).The subject of the application is a method of manufacturing articles, a method of manufacturing injection moulds, an injection mould and an article with a Velcro-type fastener on a side wall. A method of manufacturing injection moulds for manufacturing articles with a hook-and-loop fastener, comprising a base (101) and side walls (102), characterised in that: two mould parts (120) are prepared, between which, after closing the mould, there remains a space defining the shape of the base (101) and side walls (102) of the article, wherein the first mould part is a punch and the second mould part (120) is a matrix with a socket, wherein in the second mould part (120) in a place corresponding to the position of the side wall (120) of the moulded article, a through opening is formed, closed with a plate, in which, from the side of the first mould part, a pack (122) of adjacent elongated sheets (123) is placed, the circumference dimensions of which are equal to the circumference dimensions of the opening (121), wherein in each of the sheets (123) on its main surfaces (124, 125) a series of grooves (126, 127) forming hooks (103) are made inclined at an angle (α) in the range of 10 to 45 degrees, which start from the first longitudinal edge of the sheet metal, which is directed towards the first mould part, and run in a hook-like path towards the opening closing plate (121).
