The invention relates to a device and method for producing thick-walled plastic molded parts by injection molding or embossing. The device comprises a mold for injection molding or embossing, having a cavity, and is characterized in that the mold comprises a wall region adjacent to the cavity, and a body removed from the cavity and adjacent to the wall region near the cavity, wherein the body of the mold is designed for a temperature T 1 and the wall region is designed for a temperature T 2 different from the temperature T 1 . According to the method, the temperature T 2 of the wall region of the mold near the cavity is brought to and held at a value greater than the Vicat temperature T v of the plastic molding mass before and/or during the injection process, wherein the temperature T 2 is greater than the temperature T 1 of the mold body, and the temperature T 2 of the wall region near the cavity is brought to a temperature below the Vicat temperature T v of the plastic molding mass during the solidification of the plastic molding mass. The result is thick-walled molded plastic parts, such as optical lenses and the like, having reduced shrinkage sites.

A method for automatic monitoring of a production process includes automatically determining a value of an indirect process quantity from at least one value of a process quantity. From the determined value, a preliminary reference value is determined, and a preliminary reference value is respectively allocated to a reference quantity. It is checked whether the preliminary reference value lies within a range of reference values permitted for the associated reference quantity. If not, the preliminary reference value is transformed into the permitted range of reference values and the transformed value corresponds to a limited reference value. Otherwise, the limited reference value corresponds to the preliminary reference value. It is checked whether at least one value of a monitored process quantity of the current production process represents an anomaly with regard to the limited reference value of the reference quantity, and/or a composite reference value of one composite reference quantity.

Method for manufacturing impeller

Принадлежит: Mitsubishi Heavy Industries Ltd

The present invention prevents internal cracks occurring when an impeller molded using a fiber reinforced resin is manufactured by injection molding. This method for manufacturing an impeller is provided with: an injection step of filling a cavity with a molten resin containing reinforced fibers, from a gate side into which the molten resin flows, toward an opposite-gate side opposite to the gate side; and a dwell step of applying required pressure to the filled molten resin. In the injection step and the dwell step, directional cooling is performed with a temperature gradient such that the temperature becomes lower from the gate side toward the opposite-gate side. According to this method for manufacturing the impeller, the opposite-gate side shrinks with a decrease in the temperature of the molten resin since the temperature of the opposite-gate side is lower. Meanwhile, because the temperature on the gate side is increased, the molten resin can be replenished from the gate side so as to correspond to the amount of shrinkage on the opposite-gate side, and therefore the occurrence of internal tensile residual stress and cracks due to the shrinkage can be prevented.

A flow rate control valve configuring a meter-out circuit of an injection cylinder is an overlap type where a first port starts to be opened by a spool passing through an overlapping range. The control device holds a characteristic table linking a command value of a control command to the flow rate control valve and a velocity of a plunger including also the movement of the plunger which occurs due to a gap flow even if the spool is located in the overlapping range. Further, the control device specifies the command value corresponding to the target velocity set by operation of the input device based on the characteristic table, performs open control based on this command value, then performs the feedback control for realizing the target velocity.

A shaping tool includes a cooling system having one or more cooling passages configured for enhanced cooling. The cooling passages provide latent heat cooling of a heated material that is in contact with a shaping surface of the tool. Cooling fluid flows along the cooling passages in a two-phase flow regime in which a portion of the cooling fluid is liquid and a portion of the cooling fluid is vapor. A two-phase portion of the cooling passage can be shaped to follow a three-dimensional contour of the shaping surface. Opposing walls of the cooling passage can be provided by passage surfaces of separately formed pieces of the tool. The latent heat cooling provided by suitably configured cooling channels extracts more heat from the material being shaped in the tool than traditional cooling systems. 1.

Method for the secure and intentional activation of functions and/or movements of controllable industrial equipment

Methods and devices allow the secure, intentional and error-free initiation of different and directly executable industrial functions of machines or similar using a comparatively large-area touch-sensitive entry device, in particular of the touchscreen type. Operating elements or selection fields are depicted on the entry device and the operator is able to find and actuate the operating elements without visual aid or control. Using such touch-sensitive entry device of the capacitive touchscreen type, the provided operating elements or selection fields are identified by applied haptically perceptible markings. In addition, in order to initiate an operating element or an industrial function that is associated with a selection field, the operator selects the field in a first step and makes an entry by a characteristic touch gesture in a second step. This allows the control system to differentiate accidental contact, such as unsighted feeling of an identified operating element, from a deliberate operating action, and thus to reliably prevent unintentional operating actions.
