摘要： A modular system for blow molding a container. The system may include a first portion, a second portion, and a third portion. The first portion and second portion may each include a shell, a mold removably coupled to the shell, and a top plate. The third portion may include a base and a base mold. The molds may be 3D printed. The molds together may define a blow mold cavity. The modular system may be used at lab scale, pilot scale, or full production scale. The molds may be durable and smooth enough for full production scale. Some embodiments are directed to methods for making a modular system for blow molding a container.

摘要： A machine for blowing or stretch-blowing bottles or containers made of a polymer material includes molds movable on a transport system. Each mold includes a front, back, and bottom with a first and second half-molds hinged about a hinge axis and a base. Each of the molds includes a mechanism for synchronized actuation of the half-molds and the base independently from the machine's motor, to cyclically form with shaped portions, a closed cavity for receiving a preheated preform and to allow expansion by blowing or stretch-blowing the preform inside the cavity to obtain a bottle or container. The base is wedge-shaped with a horizontal closing surface facing the bottom of the mold, and an inclined surface. The actuation mechanism includes a wedge-shaped element having a surface inclining towards the front of the mold. The inclined surfaces of the base and of the wedge-shaped element are) being slidingly coupled.

摘要： Moving servo motors of molds in synchronization with the operations of platens which enables fine patterns or shapes to be formed even on a large molded article. A mold clamping device forms patterns or the like on a molded article by detecting a mold position of a second platen among first, second, third platens with digital mold opening/closing position detector, and driving servo motors for molds of the molds in synchronization with a digital mold opening/closing position signal from the digital mold opening/closing position detector.
