A tool for the injection molding of plastic molded parts has two tool halves movable in relation to each other, one of which has a mold plate carrying at least one mold insert with a multiplicity of mold cavities, or a mold plate with a mold insert support platen, which carries at least one mold insert with a multiplicity of mold cavities. The mold cavities are designed to form molded parts in conjunction with complementary cavities present on the second of the tool halves. The mold insert of each mold cavity is assigned a slide, which is arranged movably over or in a cavity-side surface of the mold insert. The slide has at least one guide element in engagement with a counterpart guide element in the mold insert. A connection bolt extends from the slide in the direction of the mold plate or of the mold insert support platen and is guided in a guide groove of a rotary ring. A plurality of connection bolts of a plurality of slides are arranged circumferentially along the circumference of the rotary ring, distributed in a corresponding number of guide grooves, and the rotary ring is connected to a drive ring arranged on the mold plate or the mold insert support platen.

There is provided a mold conveying guide device for use in replacement of a mold by conveying the mold into and out of a mold fixing position in an injection molding machine. A connecting arm is attached to the mold and projects in a direction in which the mold is conveyed into the mold fixing position. A guide roller is rotatably supported at a tip end portion of the connecting arm. The guide roller is configured to rotate while being in contact with a mold attaching surface of at least one of a fixed platen and a movable platen, and configured to guide the mold such that the mold can come close to or move away from the at least one of the fixed platen and the movable platen.

Provided is a manufacturing device for a rotor core and a manufacturing method for a rotor core in which it is possible to suitably fit a columnar core rod into a center hole of a laminated iron core, when fitting and installing the laminated iron core into a fitting recess of a first mold. A device for manufacturing a rotor core includes: a first mold; a second mold that engages with the first mold and clamps and seals the laminated iron core together with the first mold; a resin injection unit that is provided to the second mold and injects a resin material in the magnet insertion hole by using a molding machine; and a guide plate that has a through hole into which the core rod is inserted and is mounted at one end of the laminated iron core in such a manner that the through hole is in communication with the center hole of the laminated iron core, in which the guide plate has an opening diameter of the through hole on one surface side of one end side of the laminated iron core that is substantially the same as an opening diameter of the center hole, and an opening diameter of the through hole on the other side on the side of the first mold is larger than an opening diameter on the one surface side.

An injection machine which includes a mold falling prevention device that prevents a mold fixed to a mold fixing surface from falling off from the mold fixing surface and in which are provided a bottom edge restriction member at a lower portion of said mold fixing surface so that its vertical position is variable, for implementing restriction so that the bottom edge portion of the mold does not separate from the mold fixing surface, first and second intermediate restriction members at intermediate level portions of the mold fixing surface so that their horizontal positions are variable, for respectively implementing restrictions so that a one edge portion of the mold and an other edge portion thereof in the horizontal direction do not separate from the mold fixing surface, and a vertical direction position determination mechanism that receives and stops a bottom edge surface of the mold and determines a position of the mold in the vertical direction.

An injection station of an injection blow molding machine. The injection station comprises a lower die plate and an upper die plate, with lower and upper die plates being shiftable relative to one another between an open position and a closed position. The injection station additionally includes one or more lower mold halves rigidly secured to the lower die plate. The injection station additionally includes one or more upper mold halves floatingly secured to the upper die plate such that positions of the upper mold halves are configured to be adjusted with respect to the upper die plate. Each of the lower mold halves corresponds with an upper mold half to present one or more mold cavities when the lower and upper die plates are in the closed position.

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.

A mold conveyance roller unit includes: a rotatable roller main body on which a mold is to be placed; a roller support member that rotatably supports the roller main body; a base member to which the roller support member is attached together with the roller main body in a manner capable of vertical motion; and a resilient member that is fitted between the base member and the roller support member to elastically press the roller support member toward above the base member.

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

The invention relates to a bearing system for molds, wherein the mold includes a fixed part and a moving part (2), the bearing system comprising a sliding mold carrier (3) provided with vertically movable support elements (5) for bearing the moving part (2) of the mold, wherein said support elements (5) are hydraulic support elements.

The invention also relates to a method for regulating the position of a moving part (2) of a mold comprising the following steps: assembling the moving part (2) of the mold; vertically and sequentially moving the hydraulic support elements (5) until they detect a pre-determined pressure; and stopping the vertical movement of each hydraulic support element (5) when said pre-determined pressure is detected.

The invention allows for comfortable and efficient regulation of the support points of the sliding mold carrier with the moving part of an injection mold.
