An injection molding controller and other techniques are used for injecting a resin that foams substantially uniformly in a mold. An injection molding controller (2) for feeding a material to be mixed into a resin to be injected includes a control unit (3) that obtains feed information (7a) including a feed speed of the material based on resin amount information (6a) including a resin amount of molten resin filling a space in front of a screw (17c) in an injection molding device (10) per predetermined time when the screw retracts to a predetermined weighing position (19).

The present disclosure relates to a system and method for monitoring an injection molding process which may calculate injection time and packing time by attaching an acceleration sensor to an injection molding mold with bolts and measuring an amplitude change of a vibration signal of a mold during injection molding, detect mold closing and opening signals of the mold using a magnetic hall sensor, and monitor the injection molding process by measuring cycle time and cooling time, thereby simplifying installation and maintenance and reducing installation costs.

A safety mat includes: a pressure-sensitive switch mat, a surface of which is made of a flexible sheet; a step board disposed on the pressure-sensitive switch mat; and a plurality of load transferring members arranged at intervals between the pressure-sensitive switch mat and the step board. A load acting on the step board is detected by the pressure-sensitive switch mat via the plurality of load transferring members.

Provided is an injection-molded product quality analysis and monitoring system for injection-molded product quality management, the system having magnetic sensors attachably provided on a movable-side part and a fixed-side part so as to count the number of times molds have opened for injection molding, and managing the quality of products during molding-manufacturing by fixedly providing a temperature sensor at the mold so as to measure the temperature of the mold in real time, and thus measure whether the temperature is maintained within a set range, and fixedly providing an acceleration sensor or a vibration sensor at the mold so as to measure and analyze the amplitude of vibration signals, generated because of the pressure of resin injected into the mold, and the generation intervals of the vibration signals.

A method is provided for moving a movable mold mounting plate of a molding machine, in which the movable mold mounting plate is movable relative to a stationary mold mounting plate and the mold mounting plates are kinematically connected to each other, and in which a drive mechanism for moving the movable mold mounting plate is provided. Molding tool parts arranged on the mold mounting plates are brought into abutment to each other in a closed state, and a temporally changeable tilting movement of the mold mounting plates relative to each other occurs by the movement of the movable mold mounting plate. The movable mold mounting plate is moved by the drive mechanism and/or the stationary mold mounting plate is moved by an injection device in such a way that when reaching a predeterminable distance of the mold mounting plates relative to each other, a parameter representing the tilting movement of the mold mounting plates relative to each other is less than or equal to a presettable value, preferably equal to zero.

In a mould-closing unit (F) for an injection-moulding machine for processing plastics, at least one mould carrier (10), which can be moved in a longitudinal direction (L-L) of the mould-closing unit (F), is arranged on a machine base (14) and between itself and a further mould carrier (12) forms a mould-clamping space (C), in which parts of at least one cyclically openable and closable injection mould (M) can be received. At least one linear guide (16), arranged in the longitudinal direction (L-L) on the machine base (14), serves for guiding the at least one movable mould carrier (10) when there is movement in the longitudinal direction (L-L). The mould carrier is supported on the machine base (14) and/or the at least one linear guide (16) by way of a load take-up (18), which has above the at least one linear guide (16) an articulating region (20) for the at least one movable mould carrier (10), which region is connected to the movable mould carrier with a force fit or material bonding and the stiffness of which is greater in the longitudinal direction (L-L) than in a direction transverse to the longitudinal direction (L-L). The forces acting on the guide of the movable mould carrier during the operation of the injection-moulding machine are minimized by the load take-up (18) and/or the articulating region (20) being elliptical in cross section, with the minor axis of the ellipse extending in a direction transverse to the longitudinal direction (L-L) of the mould-closing unit (F).
