が悪い。2. Description of the Related Art In a conventional vertical injection molding machine, a lower mold of a mold that can be divided into upper and lower parts is fixed to a base and an upper mold is fixed to a mold clamping plate. The mold clamping plate is lowered and raised by a cylinder device to perform mold clamping and mold opening. That is, the injection molding position and the product take-out position are the same in the molding machine, and the next molding cannot be performed unless the product is taken out from the mold, resulting in poor production efficiency.

かにするものである。Further, when the mold clamping plate and the upper mold are lifted together and the mold is opened, the stroke of the mold clamping plate has a minimum gap between the upper mold and the lower mold so that the product can be taken out from between the upper mold and the lower mold. It is necessary. A large stroke of a high-power cylinder device for mold clamping leads to an increase in the size of the entire injection molding apparatus, in particular, an increase in the machine height, and the ceiling height is limited. There was a problem that it was difficult to secure the installation space, such as having to dig down. Furthermore, in order to give a long stroke to a large-power cylinder device for mold clamping, that is, a large-diameter cylinder, the amount of working oil supplied to and discharged from the cylinder device is large, and the operating time of the cylinder device is long. Also in this respect, the manufacturing efficiency of the molded product is reduced. The present invention clarifies an injection molding apparatus that can improve the productivity of injection molded products and can suppress the increase in size of the apparatus.
