In a parting locking device for an injection molding mold assembly, a first engagement element and a first spring are mounted in the base holder. With a locking plate inserted in a plate insertion hole, the first engagement element moves to a locking position where the base holder and a locking member are coupled together. When a locking bar is pulled out of a bar insertion hole, the first engagement element is pushed and moved to an unlocking position where the base holder and the locking member are uncoupled from each other.

The invention relates to a powder press (1) for producing a pressed article from a material that can be pressed, having a press frame (10), an upper and/or lower punch assembly (14) and a die assembly, which define a molding cavity, into which the material that can be pressed can be introduced, and an electric drive unit (12) which is operatively connected to the punch assemblies (14) and/or the die assembly, wherein, in order to mold the pressed article, the punch assemblies (14) and the die assembly can be moved relative to each other along a pressing axis (18) and pressed against each other by means of the electric drive unit (12). Furthermore, the operative connection between the electric drive unit (12) and one of the punch assemblies (14) comprises a toggle lever drive (16) which moves the punch assembly (14) into a pressing end position along the pressing axis (18).

A clamping device for fastening an injection mold to a tool plate comprises an upper part and a lower part, said lower part having a mounting surface arranged flat against the tool plate. First, second, third and fourth side surfaces upstand from said mounting surface, said upper part having first, second, third and fourth side surfaces. Said upper and lower parts are connected by a first bolt having an axis of symmetry defining an axis. A resilient member is arranged in connection with the first bolt between the upper and lower parts concentrically with the bolt's axis. The first bolt has a non-threaded section such that the lower part or upper part may move along the bolt in the direction of the axis.

A mold includes a stationary mold, a movable mold, a coupling unit that performs coupling and uncoupling of the stationary mold and the movable mold, a coupling portion movement unit that moves a coupling portion of the stationary mold and the movable mold in a mold closing direction, and a control unit that controls the coupling unit and the coupling portion movement unit.

A mold clamping device includes: a fixed platen; a movable platen facing the fixed platen; a mold clamping housing; a plurality of tie bars connecting the fixed platen and the mold clamping housing; a plurality of tie bar nuts respectively provided on the plurality of tie bars, and configured to adjust a distance between the fixed platen and the mold clamping housing; a toggle mechanism provided between the mold clamping housing and the movable platen; a plurality of rotation members respectively provided integrally with the plurality of tie bar nuts; one endless string-shaped force transmission member wound around the plurality of rotation members; and a rotation driver configured to transmit a driving force to at least one of the plurality of the tie bar nuts as a drive target tie bar nut.

A clamping apparatus of an injection molding machine is provided. A first driving device operates a movable platen to perform mold opening/closing. A second driving device applies a clamping force to the movable platen. A screw mechanism converts rotational power of the driving devices into linear power. By contact/separation between a first rotation plate coupled to a screw shaft and a second rotation plate, a power transmission device switches transmission of power from the second driving device to the screw mechanism. At the normal time, an urging mechanism integrally moves the screw shaft and the first rotation plate in a mold closing direction and releases the connection of the second driving device. When the mold closing is completed, the urging mechanism allows the screw shaft and the first rotation plate to integrally move in a mold opening direction, and brings the second driving device into a connected state.
