摘要:
There is provided a method of injection moulding an article. The method comprises supplying mouldable material (S1) into a supply chamber (21b), injecting mouldable material from the supply chamber (21b) into the mould via a delivery chamber using a first piston (21,a, S4), subsequently injecting mouldable material present in the delivery chamber into the mould and, during the injection of mouldable material into the mould using the second piston (21d,S6), the second piston causes the delivery chamber to be sealed off from the supply chamber (S5), allowing the mouldable material to solidify within the mould thereby forming the article and subsequently removing the article from the mould (S7). The method further comprises, when the second piston has caused the delivery chamber to be sealed off from the supply chamber, withdrawing the first piston (S8) and supplying further mouldable material into the supply chamber (S1).
摘要(中):
提供了一种注射成型制品的方法。 该方法包括将可模制材料(S1)供应到供应室(21b)中,通过使用第一活塞(21,a,S4)经由输送室将可模制材料从供应室(21b)注入模具中,随后注射可模制材料 存在于输送室中的模具中,并且在使用第二活塞(21d,S6)将可模制材料注入模具期间,第二活塞使输送室从供应室(S5)密封,从而允许 可模制材料在模具内固化,从而形成制品并随后从模具中取出制品(S7)。 该方法还包括当第二活塞已经使输送室与供应室密封时,抽出第一活塞(S8)并将更多的可模制材料供应到供应室(S1)中。
