摘要:
An injection tool for the production of components by an injection-molding method, the injection tool including several cavities for shaping one respective product, an injection nozzle for injecting plastic materials for each cavity, and an actuating device. The injection nozzle has an injection channel which can be closed by a nozzle needle in order to control the injection process. The actuating device is arranged to move the nozzle needle in an axial direction between a first end position and a second end position, with an adjustable stop being provided which defines the first end position.

A method of predicting the properties (e.g., mechanical and/or processing properties) of an injection-molded article is disclosed. The method makes use of a hybrid model which includes at least one neural network. In order to forecast (or predict) properties with respect to the manufacture of a plastic molded article, a hybrid model is used in the present invention, which includes: one or more neural networks NN1, NN2, NN3, NN4, . . . , NNk; and optionally one or more rigorous models R1, R2, R3, R4, . . . , which are connected to one another. The rigorous models are used to map model elements which can be described in mathematical formulae. The neural networks are used to map processes whose relationship is present only in the form of data, as it is in effect impossible to model such processes rigorously. As a result, a forecast relating to properties including the mechanical, thermal and rheological processing properties and relating to the process time of a plastic molded article is obtained.

A tablet detecting system ascertains whether a tablet exists in a receiving hole of a loader unit used for a molding tablet supplying apparatus or, if exists, whether the tablet has a standard size, by using a mechanical contact manner. The tablet detecting system has a push rod, a contact head, an insulation plate, a conductive assembly and a control unit. The push rod is inserted into the receiving hole and moves upward just as high as the tablet. The contact head is formed on a top of the push rod and the insulation plate is located over the contact head. The conductive assembly is formed in the insulation plate and the control unit is electrically connected to the conductive assembly. When the tablet in the receiving hole has a standard size, the contact head mechanically touches the conductive assembly and gives electrical connection to the conductive assembly, and the control unit senses the electrical connection. The conductive assembly may be a pair of conductive pads formed separately on a bottom surface of the insulation plate, or a pair of plungers inserted into a pair of cylindrical bodies each formed in the insulation plate and spaced apart from each other.

A method and a device for detecting a geometric feature of consistent molded parts takes into account the different stages of cooling due to different durations of transport of the individual removed molded parts to the inspection system. Both the geometric feature and the temperature of each molded part is measured. The detected geometric features are corrected using a calibration function taking into account the measured temperatures.

An injection molding includes: a clamping mechanism (conversion mechanism and toggle mechanism) for moving a fixed platen that retains a fixed die toward a fixed platen that retains a fixed die to bring the fixed die and the movable die into contract, and generating a clamping force therebetween; a drive source (mold opening/closing motor) for driving the clamping mechanism; a clamping force detection unit for detecting the clamping force; an elongation value detection unit for detecting an elongation value indicating the amount of elongation of a tie bar that extends as the clamping force is generated; and an abnormality determination unit for determining an abnormality in the injection molding machine on the basis of the ratio of the elongation value and the clamping force.
摘要:
An injection molding system is provided with inspection means for inspecting an insert part before a resin is injected into a mold, inspection data output means for outputting inspection data on the insert part obtained by the inspection means, and inspection data recording means for recording the inspection data on the insert part and physical quantities related to the injection of the resin into the mold in association with the cycle number of the molded article from the injection molding machine. Thus, the cause of bad molded articles, as well as that for a finished product, can be investigated in consideration of the inspection data on the insert part inserted into the mold.
摘要:
A method of injection moulding a plastics container 1 having wall(s) 2 of substantially uniform thickness using an injection mould 10 with an unsupported core 12 is disclosed. A small sliver 17 is removed from the free end of the core 12 of the mould 10 from that side of the wall which is thinnest. As a consequence on the next injection more plastic flows in that direction. Repeated optical inspection of the containers enables a balance to be achieved in which slightly asymmetric injection conditions are balanced by a slightly asymmetric container base with the result being a container with substantially uniform wall thickness.

A method for verifying tolerance of a connector molding die includes, firstly, providing a first connector molding die, and molding a first optical connector using the first connector molding die. The centers of the lenses relative to the center of the first transmission surface are located. A second connector molding die is provided. A second optical connector is molded by the second connector molding die. The central locations of the first blind holes are determined by measuring the central locations of the second blind holes based on the center of the second transmission surface. Difference values between the locations of the centers of the lenses and the central locations of the first blind holes are determined.
