Abstract
(EN) With a view to achieving a wax model injection molding method and a wax model injection molding apparatus, both of which enable efficient injection molding of a wax model and a shortening of working hours, a wax model injection molding method that comprises a step for clamping a rubber mold and then fitting a fill port of the rubber mold onto an injection nozzle 4, a step for discharging the rubber mold filled with wax resin out of a clamp part 5, and a step for feeding a next rubber mold into the clamp part 5 from which the filled-up rubber mold has been discharged, and a wax model mold injection apparatus for implementing said method, are both configured to be able to perform the two steps, which are the step for discharging the filled-up rubber mold out of the clamp part 5 and the step for feeding a next rubber mold into the clamp part from which the filled-up rubber mold has been discharged, as a single step for, as sequence of operations, moving, after a rubber mold is filled up with wax resin, a next rubber mold into the clamp part 5, pushing out and discharging the filled-up rubber mold out of the clamp part, and feeding a next rubber mold into the clamp part.
(FR) En vue d'obtenir une méthode de moulage par injection de modèle de cire et un appareil de moulage par injection de modèle de cire, les deux permettant un moulage par injection efficace d'un modèle de cire et une réduction du temps de travail, une méthode de moulage par injection de modèle de cire qui comprend une étape de serrage d'un moule en caoutchouc et ensuite l'ajustement d'un orifice de remplissage du moule en caoutchouc sur une buse d'injection 4, une étape de décharge du moule en caoutchouc rempli de résine de cire hors d'une partie de serrage 5, et une étape d'introduction d'un moule en caoutchouc suivant dans la partie de serrage d'où le moule en caoutchouc rempli a été déchargé, et un appareil d'injection de moule de modèle de cire pour mettre en œuvre ladite méthode, sont tous deux configurés pour pouvoir effectuer les deux étapes, qui sont l'étape de décharge du moule en caoutchouc rempli hors de la partie de serrage 5 et l'étape d'introduction d'un moule en caoutchouc suivant dans la partie de serrage d'où le moule en caoutchouc rempli a été déchargé, en une seule étape, comme séquence d'opérations, de déplacement, après le remplissage d'un moule en caoutchouc avec de la résine de cire, d'un moule en caoutchouc suivant dans la partie de serrage 5, de poussée et de décharge du moule en caoutchouc rempli hors de la partie de serrage, et d'introduction d'un moule en caoutchouc suivant dans la partie de serrage.
(JA) ワックスモデル射出成型を効率よく行い時間の短縮化を図ることができるワックスモデル射出成型方法およびワックスモデル射出成型装置を得るために、ゴム型をクランプしてゴム型の注入口を射出ノズル4に嵌合する工程と、ワックス樹脂が充填された充填済みゴム型をクランプ部5内から排出する工程と、充填済みゴム型を排出したクランプ部5内に次のゴム型を供給する工程を含むワックスモデル射出成型方法およびこの方法を実施するワックスモデル射出成型装置において、充填済みゴム型をクランプ部5内から排出する工程と、充填済みゴム型を排出したクランプ部内に次のゴム型を供給する工程の2つの工程を、ゴム型へのワックス樹脂の充填後に次のゴム型をクランプ部5内へ移動させ、充填済みゴム型をクランプ部内から押し出し排出させるとともに、次のゴム型をクランプ部内に供給するようにした一連の動作で行う1つの工程で行えるようにした。
