    摘要： A molding machine in which a load cell unit is mounted on an end portion of one of a plurality of connecting bars elastically deformable (extensionally deformable) due to a load (tensile load) during the operation of molding. At least partially any connecting bar where the load cell unit is not mounted, that is, any connecting bar other than the predetermined connecting bar where the load cell unit is mounted, includes a portion whose diameter is made a predetermined distance smaller than a diameter of the predetermined connecting bar where the load cell unit is mounted. Thus, the quantities of deformation can be equalized all over the connecting bars without using any dummy load cell unit.

    摘要： The invention relates to a device and method for detecting a force on an injection moulding machine for processing plastic materials. According to said invention, a first element (100) interacting with a mechanical drive and movable at least indirectly thereby in a direction of movement (x) is displaced during said displacement with respect to a second element (200) positioned near the first element (100) or oppositely thereto. A force measuring device (D) is used for determining the force applied on the first (100) and/or second (200) element by the actuation of the injection moulding machine produced by the relative displacement thereof between the first (100) and second (200) elements. A hydraulic chamber whose size is modifiable during the relative displacement associated with a change in pressure of a fluid medium in said hydraulic chamber is firmed between the first (100) and second (200) elements, wherein said change in pressure forms an input signal for adjusting the force or pressure and a pressure-relief valve (30) is used for bypassing the hydraulic medium to a hydraulic medium container (35), when the predetermined or predeterminable presser is exceeded in the hydraulic chamber (10), thereby making it possible to obtain a device and method for detecting a force on an injection moulding machine which makes it possible to determine said force in a favourable alternative manner and simultaneously ensure an overload protection.

    摘要： Rather than developing full closure tonnage for a substantial portion of the duration of an injection cycle, closed loop control of the clamp pressure (such as through control of hydraulic pistons) permits clamp pressure to balance exactly, but preferably slightly exceed, the instantaneous injection pressure. A first approach mimics the injection pressure profile with time, whereby applied tonnage is varied with time according to sensed pressure measurements. A second approach looks to pre-stored or historically accumulated injection pressure information and, instead of varying the tonnage, applies a constant tonnage reflecting the maximum recorded or most likely injection pressure to be experienced in the mold (as recorded stored in a look-up table associated with the particular mold configuration). A machine controller (80, 82) causes the application of applied tonnage through the platen (16, 17) and tie-bars (19, 20) of an injection molding machine (10). Pressure sensors (66-74) located either on a mold surface (50), relative to stack components (58-64) and/or relative to a force closure path of permit a microprocessor (82) to control applied clamp closure tonnage. In this way, the system consumes less power and component wear is reduced.
