Disclosed is a method for making a flexible container. The method implements an injection mold having a collapsible core that expands/moves to define the apertures and, in some embodiments, holds a flexible film in place during the injection mold process and collapses/moves back post-injection molding to allow for the flexible container to be readily removed from the die. In addition, the method described includes a post-injection molding anneal process that is implemented to allow the flexible film to shrink so as to provide for form-fitting of the film to the molded portion of the container.

A resin molded product (10) includes a resin molded product main body (11), and a protrusion (12) integrally formed with the resin molded product main body (11) and protruding from the resin molded product main body (11). At injection molding of the resin molded product (10), molten resin flows through a portion (C-1) corresponding to the protrusion (12) in a cavity (C) defined by a pair of molds (20, 30). A concave portion (14) is formed on a rear side of the protrusion (12), and a bulging portion (12a) having a hollow bag shape is formed on a front side of the protrusion (12).

A mold and a relative molding process for the manufacture of sporting helmets, in particular cycling helmets. The mold includes a frame provided with at least one molding concavity; a counter frame engageable to the frame to hermetically close the respective molding concavity and allow the execution of at least one molding cycle. The mold further includes at least one intermediate support element for supporting and positioning one or more components of the sporting helmet to be manufactured inside the respective molding concavity of the frame. The intermediate support element is kept inside the respective molding concavity during the entire molding cycle in order to keep the components of the sporting helmet to be manufactured in their assigned positions.

Provided is a resin molding apparatus that can suppress a molding problem caused by a variation in a thickness of an object to be molded or suppress a variation in a thickness of a resin molded part, and can perform a mold releasing operation. A resin molding apparatus includes: a molding mold having one mold and the other mold; one mold wedge mechanism; and one mold cavity block driving mechanism. In a state that a height position of one mold cavity block is set using the one mold cavity block driving mechanism and a position in a direction away from the other mold in the one mold cavity block having been moved to the height position is fixed to be limited using the one mold wedge mechanism, a mold releasing operation can be performed using the one mold wedge mechanism and the one mold cavity block driving mechanism.

A vertical injection molding machine includes a mold clamping device configured to clamp a mold and an injection device configured to inject an injection material. The mold clamping device includes a fixed plate, an upper movable plate that is driven up and down with respect to the fixed plate, and a turntable provided on the fixed plate and is rotatable with respect to the fixed plate. In a case the turntable is provided with a plurality of types of molds configured to mold different molded articles, when the turntable is rotated, one type of the molds is switched to a molding target mold and the other type of the molds is switched to a standby target mold, and the molding target mold is clamped by driving of the upper movable plate and is injected with the injection material.

A mold clamping device includes a base, a stationary platen fixed to the base and supporting a stationary mold, a movable platen movable on the base and supporting a movable mold, and a mold clamping mechanism for clamping the movable mold against the stationary mold. Tie bars extend from the stationary platen completely through both the movable platen and the mold clamping mechanism. A shaft supporting plate is fixed to the base and has openings through which the tie bars slidably extend for supporting the tie bars. The shaft supporting plate terminates at its lower end portion in two spaced-apart shoes that are fixed to the base. The bottom surface of each shoe has a larger area than the cross-sectional area of the shaft supporting plate situated vertically above the shoe.
