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.

A magnet embedded core is manufactured in a stable manner even when using a die clamping device having a large rated clamping force by preventing an excessive pressurizing force from being applied to a laminated iron core, performing the clamping with an appropriate pressurizing force so to minimize leakage of the resin out of magnet insertion holes, and suppressing a reduction in the geometric and dimensional precision of the laminated iron core. A die clamping device for driving a moveable platen in a direction toward and away from a fixed lower platen is configured to include a toggle link mechanism. In a fully extended state of the toggle link mechanism, an upper die abuts an end surface of the laminated iron core to close openings of the magnet insertion holes and pressurize the laminated iron core in a laminating direction.

A method including a first step of performing clamping of a mold, injection and dwelling in an injection molding machine, a second step of performing a conveyance and a cooling of the mold outside of the machine, and a third step of performing a conveyance of the mold into the machine, an opening of the mold and an ejection of a molded part in the machine. The second step is performed for a first mold, the third step and the next first step are performed for a second mold. The first mold is conveyed by a first conveyance apparatus which is arranged on one lateral side of the machine. The second mold is conveyed by a second conveyance apparatus which is arranged on the other lateral side and is independently driven from the first conveyance apparatus.

The injection moulding of articles formed by plastic materials having different characteristics, for example of different colours, is carried out in a single injection cycle in which the first and the second plastic materials are injected into a first and into a second zone of a mould cavity by first and second injectors controlled according to specific modes so as to define a shape and/or a position of a weld line.

An apparatus for controlling the rate of flow of mold material to a mold cavity, the apparatus comprising: an injection molding machine and a manifold; an actuator interconnected to a valve pin having a tip end; a valve system in fluid communication with the actuator to drive the actuator at one or more rates of travel, the valve system having a start position, one or more intermediate drive rate positions and a high drive rate position, the start position holding the valve pin in a gate closed position; a controller that instructs the valve system to move from the start position to the one or more intermediate drive rate positions and to remain in the one or more intermediate drive rate positions for one or more corresponding predetermined amounts of time.

Disclosed herein, amongst other things, are structure and steps for positioning a first mold part of a mold on a mold mounting face in an injection molding machine. In particular, the structure and steps may include a positioner that is configured to connect the first mold part to part of the injection molding machine, wherein the positioner is adjustable to position the first mold part across the mold mounting face.

A system and method for controlling an actuator which actuates an axially displaceable pin valve of an apparatus for injection molding of plastic materials, where the control system includes an electronic control unit of the actuator which adjusts at least one among position, speed and acceleration of the pin valve, and a position sensor which detects a position of a plunger of the actuator and is operatively connected to the electronic control unit. The position sensor indirectly detects the position of the plunger of the actuator.

An ejection device having a pushing device that can be moved in translation along a first axis, an ejection element is translatable along a second axis different from the first axis, and a transfer device connecting the pushing device and the ejection element. The transfer device includes a transmission chain having at least two transmission links which are translatable in a sliding direction. The ejection device further includes an adjustment wedge mounted on the pushing device, the adjustment wedge having an adjustment surface forming an adjustment angle, with the transmission chain being mounted on the adjustment surface.

A method of detecting and compensating for a non-operational mold cavity in an injection molding apparatus having a plurality of mold cavities and an injection molding screw or ram includes injecting, via the injection molding screw or ram, a molten thermoplastic material into the plurality of mold cavities. The method includes measuring a first process parameter of the injection molding apparatus at a pre-determined time during or after the injecting. The method also includes determining, based on the first process parameter, whether one or more mold cavities of the plurality of mold cavities are non-operational. Then, when it is determined that one or more mold cavities are non-operational, the method includes automatically adjusting the first process parameter or a second process parameter of the injection molding apparatus.

A hot runner process controller configured to monitor the status and operation of a hot runner system to autonomously generate information to improve the quality of injection molding process of a hot runner system having an inlet nozzle, one or more manifolds and one or more nozzles with actuator or without actuator, and one or more heating elements, the hot runner process controller is self-operating, and independent from the injection molding machine, includes: one or more sensors located on, in or at the hot runner system to detect the status and/or the operation of the hot runner system, and a processing unit and a memory. The processing unit is connected to the one or more sensors, wherein the memory stores data and program codes. The processing unit is configured to load and execute the program code to compare sensor information with the stored data and to determine if the hot runner system is in an operable status, and in case the hot runner system is in an operable status, configured to generate status information to activate the one or more heating elements and/or the one or more actuators enabling a production operation of the injection molding machine. In case the hot runner system is not in an operable status, configured to generate status information to deactivate the one or more heating elements and/or close or deactivate the one or more actuators disabling a production operation of the injection molding machine.
