An example medical agent filling system may comprise a container having an exterior housing formed by a rigid wall and a removable lid. The system may further comprise a fluid introduction port. The system may further comprise a fluid bus extending from the fluid introduction port to a plurality of dispensing sharps. The system may further comprise a plurality of reservoir assemblies each having a main interior volume sealed by a septum. Each of the septa may be in a punctured state with a respective dispensing sharp of the plurality of dispensing sharps extending therethrough. The fluid bus and main interior volumes of the reservoir assemblies may form an isolated fill environment.

A molding apparatus is proposed for manufacturing a molded component. The molding apparatus may include an upper half mold and a lower half mold cooperatively coupled with each other. A mold cavity is defined between the upper half mold and the lower half mold. The molding apparatus further includes one or more compressing channels formed in the lower half mold and in fluid communication with the mold cavity; and one or more compressing rods, wherein each of the one or more compressing rods is slidably received in a respective one of the one or more compressing channels, wherein a top surface of each of the one or more compressing rods defines a compressing recess within the respective one of the one or more compressing channels.

A production mold for a split-type grit-textured packaging bottle includes fixed-mold and movable-mold assemblies. The fixed-mold assembly has top and bottom provided with injection channel and fixed-mold A plate respectively. Fixed-mold insert(s) installed in the fixed-mold A plate communicates with the injection channel, and corresponds to a concave cavity having bottom consistent with product's closed end in shape. Two inclined guide pillars are provided the concave cavity's two sides. The movable-mold assembly's top has a movable-mold B plate provided with a B-plate insert with a concave cavity-facing mold core. The B-plate insert's end relative to the product forms internally as an inverted cone structure. A pushing assembly includes a movable-mold push plate movable on the movable-mold B plate and having a top provided, relative to the concave cavity, with side sliders for correspondingly driving the guide pillars. Sliders'product-facing sides have structures matching grit texture on the product's outer wall.

An injection molding system includes an injection molding apparatus to which a mold is attached, and an ejection apparatus that ejects a molded product from the mold in a mold open state in which the mold is open, wherein the injection molding apparatus is configured to enable an operator to eject the molded product from the mold at a predetermined work position, and the injection molding apparatus is disposed between the work position and the ejection apparatus.

A cam mechanism allows a slide ejector plate and slide ejector pins to move relative to a slide core as the slide core moves. Alternatively, the cam mechanism allows the slide ejector plate and the slide ejector pins to move with the slide core. This eliminates the need for a dedicated hydraulic cylinder for moving the slide ejector plate and the slide ejector pins. The number of parts of the die casting device can thus be reduced.
