The invention relates to a retaining device (1) for a rotatable mold center part (2) in an injection molding machine, the retaining device comprising a plate (17) used for retaining the rotatable mold center part (2), the plate being rotatable about an axis of rotation (16) and driven by means of a motor (20). The retaining device (1) comprises a lower cross member (10), which is mounted movably in the longitudinal direction (x) on guide rails (7) while supported on a machine bed (6) of the injection molding machine by means of first bearing blocks (8). The retaining device (1) comprises second bearing blocks (23), by means of which the lower cross member (10) is supported in the circumferential direction relative to lower beams (5) of the injection molding machine.

A mounting stand for an injection molding machine has a base member and an erecting member, to which an injection apparatus is attached, vertically arranged on the base member, and is movable with respect to a support supporting the base member. The mounting stand includes a base member protruding portion provided upward from the base member around a portion at which the base member comes into contact with the erecting member, and an anchored portion at which a side surface of the base member protruding portion is anchored to a side surface of the erecting member.

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.

In the present invention, constructed is a highly reliable system that does not allow unforeseen conditions to occur in the remote diagnosis of a clamp device. All combinations of status of a state detection switch mounted on a clamp device are anticipated in advance by a recursive method, and the states are defined with no omissions. A control unit 9 includes: a main body memory 9c that stores the ON/OFF state of a state switch together with the status of an injection molding machine main body, the clamp status and time information; and a main body communication unit 9d which is capable of short-range wireless communication. A message diagnosing a failure is stored in a smartphone 12 for all combinations of the ON/OFF state of the state detection switch for each of the following cases: whether in mold replacement mode or not; and whether a clamp device is in a clamped state or an unclamped state, or in a state other than the forgoing. The history of the ON/OFF state of the state detection switch with respect to the status of the main body and the clamp status is read from the main body memory 9c by wireless communication, and a corresponding message is displayed.

An injection molding system includes an injection molding apparatus that performs injection molding, a first conveyor apparatus on one side of the injection molding apparatus to eject and insert a first mold through a first opening of the injection molding apparatus, and a second conveyor apparatus located on a second side of the injection molding apparatus to eject and insert a second mold through a second opening of the injection molding apparatus, where the improvement of the injection molding apparatus includes a first door to cover the first opening, a second door to cover the second opening, and a controller that prohibits injection molding with the first mold in a case where the second door is opened.

Provided are a production method of a mold having a recessed pattern, and a manufacturing method of a pattern sheet having good accuracy and excellent productivity. The production method of a mold includes: a step of preparing an electroform having a protruding pattern and a mold having a first mold and a second mold forming a cavity; a step of fixing the electroform excluding an end portion of the electroform to the first mold; a clamping step of clamping the electroform excluding the end portion of the electroform and a region of the protruding pattern between the first mold and the second mold to form the cavity; and an injection step of filling the cavity with a resin.

On a foam plastics molding machine, a molding unit, defined by a mold and an interface frame equipped with a number or quantity of plastic molding material and operating fluid inlets, is loaded into a raised window in a fixed frame of the machine by positioning the molding unit in a fixed position on a trolley; positioning the trolley astride a fixed platform; raising the platform so that vertical ribs on the interface frame slidably engage corresponding vertical guides forming part of the machine and on a level with the window; connecting the guides to the ribs; and moving the guides towards the window.

A rapid mold replacing device for use in molding machine comprises: a molding machine, including a machine table defined with an operating zone and an open space adjacently arranged; a carrier, disposed on the machine table and allowing a mold to be positioned thereon, driven by a transmission mechanism, thereby capable of being moved and positioned between the operating zone and the open space; and an open/close driving mechanism, including a pair of moveable plates oppositely disposed and arranged at two sides of the operating zone, wherein the pair of moveable plates are driven by the open/close driving mechanism, thereby forming an opening/closing motion; two sides of the mold are respectively disposed with a lateral plate at a location adjacent to each of the moveable plates, and at least one locking mechanism is disposed between the lateral plate and the moveable plate.

An injection molding machine includes a machine base extending lengthwise along a machine axis. The base has a platen support portion extending along a first axial portion of the base, and an injection unit support portion extending along a second axial portion of the base. The machine further includes a platen supported by the platen support portion for carrying a mold half apparatus. The machine further includes a first injection unit supported by the injection unit support portion for discharging a first melt through the platen into a first mold inlet of the mold half apparatus, and a second injection unit supported by the injection unit support portion for discharging a second melt around the platen into a second mold inlet of the mold half apparatus.

A molding device for producing thermoplastic articles and its method of use, wherein the molding device comprises a rigid bottom plate, a rigid top plate adapted to be removably coupled to the said bottom plate, a 3D-printed die or insert in the shape of half of the said article removably inserted into a CNC milled mold cavity. The molten thermoplastic material is injected in to the molding device through an injection port to form the thermoplastic in the shape of 3D-printed die or insert, wherein the thermoplastic article is a fishing lure.
