It is disclosed an injection moulding press comprising a plurality of moulds, with an injector for each mould, mounted on platform with which they can be rotated along a circumference.

The invention relates to a molding device for producing a product by means of injection molding. The molding device comprises a central mold part, which can be rotated about a rotational axis and which comprises at least one inner mold half arranged on the central mold part, and at least one outer mold half, which interacts with the inner mold half in order to form cavities in a closed configuration of the molding device and which is arranged in a movable manner relative to the inner mold half in a first direction (x). Furthermore, at least one first connector element arranged on the central mold part and at least one second connector element arranged on the outer mold half are provided, said second connector element being operatively connected to the first connector element at least in a closed configuration of the molding device.

Provided is an injection molding machine (1) including a plasticizing unit (2), an injection unit (3), a communication path (5a) configured to communicate therebetween and having an opening (5b) on the plasticizing unit side which is located on an axis of the screw (21), and a backflow prevention mechanism part (6) configured to close and open the opening on the plasticizing unit side by advancing and retreating the screw (21) in the axial direction, wherein the backflow prevention mechanism part (6) includes a tapered wedge portion (61) having an inclined surface (61a), a driving portion (63) which moves the wedge portion in the forward and backward directions, and a pressing member which is pressed against the inclined surface (61a) by forward movement of the wedge portion and moves the screw toward the opening on the plasticizing unit side.

This mold device has a rotary core that rotates about a shaft member as a rotation center by being provided with a rotational driving force directly from a rotation driving means. A restriction core is interposed between the rotary core and a mold body to restrict the rotation of the rotary core. That is, the rotary core becomes rotatable when the restriction core is withdrawn from between the rotary core and the mold body.

The invention relates to a retaining device for a rotatable center block in an injection molding device, comprising a lower rotary plate rotatable about an axis of rotation and driven by a motor, the lower rotary plate being used for retaining the rotatable center block. The retaining device comprises a lower cross member, which is mounted movably in the longitudinal direction (x) on guide rails while supported on a machine bed of the injection molding device by means of first bearing blocks. The retaining device can have two bearing blocks, by means of which the lower cross member is supported in the circumferential direction relative to lower beams of the injection molding device. For a further increase in efficiency, the center block has a main body made of a material of lower density than a coupling plate operatively connected thereto.

An assembly appliance for mould tool parts of an injection moulding tool is disclosed, the assembly appliance including an assembly plate configured for insertion into an injection moulding machine and including a tool carrier for receiving first mould tool parts to be assembled; and an assembly frame having a guide system for a translatory displacement of the assembly plate along a longitudinal extension of the assembly frame, and a support device for stationary support of a second mould tool part which corresponds to at least one of the first mould tool parts.

An injection molding device (1) includes a center part (3) and a rotating device (2) for rotating the center part (3) in the injection molding device (1). The rotating device (2) includes a base (4) supported with respect to an injection molding machine. A thereto attached column (5) extends to an axial direction (z) above the base (4). A sleeve (6) coaxially surrounds the column (5) and is at least partially arranged in the center part (3). The sleeve (6) rotates with the center part (3) around the column (5). The column (5) is arranged removable with respect to the center part (3).

A plastic injection molding machine and molding method related to an injection molding machine for stack molds, wherein the central portion of the mold remains fixed and it has two molding faces that act on the fixed central portion by means of a hydraulic chamber that produces the clamping force and prevents the deformations due to bending on the molding faces. Likewise, it relates to a molding method.

Multi-step method for producing a soundproof composite cover for internal combustion engines and product thus obtained, producing a cover made of thermoplastic material and insulating foam. The method uses a multiple mold with first and second cells, having male and female elements, the cells taking a first closed configuration and a second open configuration; the method including: closing the multiple mold and injecting the thermoplastic material through a channel from a hot chamber to the first cell; the thermoplastic material solidifies and the multiple mold is opened to move the solidified thermoplastic material from the first cell to the second cell; closing the multiple mold and, while a new injection occurs in the first cell, an insulating foam is injected into the second cell; and opening the double mold and, while the finished product is extracted from the second cell, a new transfer occurs from the first cell.

A molding method includes: setting a bus bar at a first mold main body portion of a fixed mold by supporting a terminal base of a tuning-fork terminal with a terminal base receiving portion of the fixed mold in a state where the tuning-fork terminal is protruded outside a cavity formed by the first mold main body portion of the fixed mold and a second mold main body portion of a movable mold being joined together; joining the movable mold together with the fixed mold by abutting an abut step portion of the movable mold to a receiving abut step portion of the fixed mold and nipping the terminal base of the tuning-fork terminal with the terminal base receiving portion and a terminal base abut portion of the movable mold; and injecting resin into the cavity in the nipped state.
