Abstract
Modifikovaná vstřelovací trubice (9) pro jádrařské vstřelovací stroje, sestávající z trubkové části (17) opatřené horní a spodní přírubou (13, 14), přičemž po okraji trubkové části (17) jsou vytvořeny otvory (18) v okrajových pásech (15), přičemž stěna trubkové části (17) obsahuje, definováno od vnitřního průměru k vnějšímu, první vnitřní vrstvu (19), která je tvořena vinylesterovou pryskyřicí obsahující prach karbidu křemíku, na této vnitřní vrstvě (19) je uložena rohož (20) ze skelných vláken jako první výztuž, na této rohoži (20) je uložena druhá vrstva (19a), opět z vinylesterové pryskyřice obsahující prach karbidu křemíku, přičemž na ní je uspořádána třetí vrstva (21) vytvořena ve vrstvách na sebe navíjeným skelným vláknem prokládaným vinylesterovou pryskyřicí, přičemž skelné vlákno v této třetí vrstvě (21) tvoří druhou výztuhu pro výrazné zvýšení celkové tuhosti a stability trubice (9) a na třetí vrstvě (21) je uspořádána vnější vrstva (22) tvořená vinylesterovou pryskyřicí.Modified injection tube (9) for core shot machines, consisting of a tubular portion (17) provided with an upper and lower flange (13, 14), wherein openings (18) in edge strips (15) are formed along the edge of the tubular portion (17), wherein the wall of the tubular portion (17) comprises, defined from the inner diameter to the outer, a first inner layer (19) which is composed of a vinyl ester resin containing silicon carbide powder, a glass fiber mat (20) is disposed on the inner layer (19) as the first reinforcement, the second layer (19a), again of the vinyl ester resin containing silicon carbide dust, is deposited on the mat (20), on which a third layer (21) is formed formed in layers by a glass fiber interleaved with vinyl ester resin, with glass the fiber in this third layer (21) forms a second reinforcement to significantly increase overall stiffness and sta An outer layer (22) formed by a vinyl ester resin is provided on the third layer (21).
