An intermediate mold disposed between a stationary-side mold and a movable-side mold in a mold unit of an injection molding machine, the intermediate mold including: a mold portion that performs a mold opening and closing operation with a facing mold facing one of the stationary-side mold and the movable-side mold; a guide bar that penetrates through the mold portion, and that guides the mold opening and closing operation; and a rotary frame body that includes a rotary shaft, and that rotates together with the guide bar and the mold portion in a state where the rotary frame body is joined to the guide bar. The mold portion is temporarily gripped by a tip part of the guide bar, and is temporarily gripped by the facing mold.

An intermediate mold is disposed between a stationary side mold and a movable side mold in a mold unit of an injection molding machine, the intermediate mold includes: a mold section that performs mold opening and closing operations with a facing mold of the stationary side mold and the movable side mold; a rotating frame body that is rotated together with the mold section by a rotary shaft; a support section that supports both sides of the rotating frame body via shaft bodies; and a rotation drive section that transmits a rotational force to the rotating frame body, in which the support section accommodates at least a part of the rotation drive section.

An intermediate mold disposed between a stationary side mold and a movable side mold in a mold unit of an injection molding machine includes: a mold section performing mold opening and closing operations with a facing mold of the stationary side mold and the movable side mold; a rotating frame body rotated together with the mold section by a rotary shaft; a support section supporting both sides of the rotating frame body via shaft bodies; and a rotation drive section transmitting a rotational force to the rotating frame body, in which the mold section and the shaft bodies include a hollow portion that allows a pipe through which a fluid passes or an electrical wire to be disposed, and both end portions of the hollow portion form inlet/outlet ports through which the pipe or the electrical wire can enter and exit in a rotation axis direction of the shaft bodies.

There is provided an intermediate mold disposed between a stationary-side mold and a movable-side mold in a mold unit of an injection molding machine, the intermediate mold including: a support portion that supports, in an attachable and detachable manner, both sides of a rotary shaft of a mold portion that is rotated; and a connection member that is detachably connected to a top side of the support portion in a top-bottom direction, in which, in a case where the mold portion is attached to and detached from the support portion, the mold portion is attached and detached through a space formed by removing the connection member from the support portion.

The invention relates to an injection molding device (1) with at least one first and at least one second outer mold half (11, 12), which are arranged in a movable manner relative to each other in a first direction (x). A central part (5) which can be rotated about a rotational axis (17) is arranged between the two mold halves, said central part having an upper part (6) and a lower part (7). First inner mold halves (13) are attached in pairs to the lower part (6), and second inner mold halves (14) are attached in pairs to the upper part (7). Said inner mold halves interact with the in a closed position thereto assigned first and second outer mold halves (11,12) in order to form cavities. The first and the second inner mold halves (13, 14) and the assigned first and second outer mold halves (11, 12) form a lower and an upper production plane (32, 33).

There are provided an article manufacturing method and a manufacturing apparatus capable of removing a molded article from an intermediate mold in an injection molding machine. For this purpose, the intermediate mold disposed between the first and second molds in the injection molding machine is provided with a removal mechanism for removing the molded article.

Disclosed are an injection molding device and an injection molding method for an optical element, relating to the technical field of injection molding. The device includes an injection assembly, a fixed mold installation plate and a movable mold installation plate. The injection assembly is configured to melt and inject plastic material. The fixed mold installation plate is provided with at least two injection stations along a horizontal direction, and the injection assembly is configured to inject the plastic material into the injection stations. The movable mold installation plate is provided with a rotary plate assembly, and the rotary plate assembly is configured to drive the mold to rotate at a fixed angle each time to form N molding stations.

Disclosed are a cap assembly, a secondary battery including the a cap assembly, and a method of manufacturing the a cap assembly. The disclosed cap assembly and secondary battery can be made by the disclosed methods that reduce process difficulty and the process time, and provide improved cap assembly reliability. The cap assembly includes a lower conductive plate, an upper conductive plate disposed above the lower conductive plate, a lower resin layer fused to a bottom surface of the lower conductive plate, and an upper resin layer fused to a top surface of the lower conductive plate, a bottom surface of the upper conductive plate, or the top surface of the lower conductive plate and the bottom surface of the upper conductive plate.

A molded product manufacturing method includes the steps of: molding a first component and a second component between a first surface and an A surface; molding a third component and a fourth component between the first surface and a B surface and engaging the second component with the first component held on the A surface; welding the first component and the second component to mold a first integral molded product and engaging the fourth component with the third component held on the B surface; and welding the third component and the fourth component to mold a second integral molded product.

A mold includes a rotatable portion, a frame portion, a first and second portion, and a production unit. The rotatable portion has a plurality of surfaces and a plurality of forming portions. The plurality of surfaces is each provided with one of the plurality of forming portions, each having the same shape. The frame portion rotatably supports the rotatable portion. The first portion defines a cavity by coming into contact with one surface of the plurality of surfaces by clamping the mold. The second portion comes into contact with another surface of the plurality of surfaces different from the one surface by clamping the mold. The production unit attached to the frame portion.
