摘要： The retraction of the screw is controlled on the basis of the pressure deviation between the set resin pressure and the detected resin pressure. Furthermore, the screw is caused to rotate at a set speed. Moreover, when the deviation between the metering completion position and the current screw retraction position drops to a value that is equal to or less than a set value, control of the retraction of the screw based on the pressure deviation is stopped, and the control is switched to positioning control based on the positional deviation. Furthermore, a screw rotational speed command in which the pressure deviation component between the set resin pressure and the current resin pressure is corrected from the screw rotational speed component that is decelerated in proportion to the positional deviation is determined and output.

摘要： A method for controlling a screw position of a screw in an injection molding machine uses a high-speed injection and high-speed depressurization method to perform the entire injecting process by controlling speed of the screw. The screw is moved forward to a predetermined first position from an injection start position, and when the screw reaches the predetermined first position, the screw is moved backward to a predetermined second position. The speeds of the forward and backward movement of the screw are controlled in accordance with a screw-position/speed characteristic pattern which is measured in advance, and which is derived from the equation V=(2·K·S)½ where V is screw speed, K is screw acceleration, and S is screw position.

摘要： An injection is carried out under a certain molding condition with a nozzle in an injection molding machine left open to sample an injection pressure Pr in every certain cycle for storing. Detected pressure data Pr(0) to Pr(N) for one shot is stored as reference pressure data Pr0(0) to Pr0(N). When defective molding occurs or when a resin lot is changed or the like, the injection is carried out with the nozzle left open under the same molding condition as that used in obtaining the reference pressure data to obtain the detected pressure data Pr(0) to Pr(N). Waveforms of the detected pressure data Pr(0) to Pr(N) and reference pressure data Pr0(0) to Pr0(N) are graphically represented so that variation of the molding condition is observed. It is assumed that if there are any differences, a problem resides in the resin, while if there is no difference but the defective molding occurs, the problem resides in a mold.

摘要： Reinforced plastic pellets comprise thermoplastic material and reinforcement particles that are less than 15% of a total volume of the pellets, and at least 40% have a thickness of less than 50 nanometers. A manifold (56) has at least two spaced valve gates (64) that are independently opened and closed as directed by a controller (68) to selectively communicate the manifold to a cavity. A primary injection pressure is applied to the plasticized pellet material in the manifold (56) to fill the cavity through sequential opening and closing of the gates (64). A lower secondary injection pressure is applied to the material in the manifold to continue filling the cavity. The gates are closed to seal the manifold from the cavity when the cavity is filled. The material is held within the manifold in compression by the valves while the cavity is open to prevent expansion of the material.

摘要： The invention relates to an electric injecting molder and an injection velocity and injection pressure controlling method for an electric injecting molder, and it is an object of the present invention to make it possible, in injection molding by an electric injection molder, to mold stable resin products having a minimized dispersion in the quality even if the operation environment varies. When an injection screw (23) disposed in an injection cylinder (22) is driven to move in forward and backward directions by an electric motor (29A) to inject resin material (3) in the injection cylinder (22) into a metal mold (1, 2) to fill the metal mold (1, 2), the electric motor (29A) is first velocity-controlled to fill the resin material (3) into the metal mold (1, 2), and, after the filling, the electric motor (29A) is pressure-controlled to replenish the resin material for shrinkage of the resin. Upon the velocity control, a velocity target value for the injection screw (23) is corrected in response to a force detection value so that the velocity target value for the injection screw. (23) may decrease as the force detection value increases to perform velocity feedback control of the electric motor (29A) so that a velocity detection value from velocity detection means may be equal to the velocity target value.

摘要： In an injection molding machine utilizing a setting method of the present invention, there is substantially no limitation in numbers to steps of an injection speed and a holding pressure, and in addition to rectangle, slope, polygonal line and flat, an arc can be designated as a shape mode. Because of using codes to define the shape mode, the setting operation becomes easy. In order to form one injection speed control pattern, the mix of shape modes is utilized. Also, in the present setting method, a plurality of code data predeterminedly defined are input sequentially in time, thereby setting the injection speed control pattern or pressure holding control pattern. The code defines a kind of function which figures out an injection speed command data or a holding pressure command data corresponding to each stroke position or time.

摘要： An ejector pin with a pressure sensor is provided, of which the sensor output can be utilized without any correction even in different diameter thereof, so that no design changes are required according to loads to the ejector pin. The ejector pin has a bar portion for extruding a molded component and a sleeve portion slidably housing the bar portion. The end of the bar portion faces the cavity from the opening at the end of the guide portion. A housing room is defined by the step portion at the lower end of the sleeve portion. A strain producing portion with an U-shaped cross section fixed on the base end of the bar portion is disposed inside the housing room. A strain sensor is attached on the lower surface of the beam of the strain producing portion. Only the area of the end of the bar portion is related to the pressure detection. When the pressure of a resin is applied on the end of the bar portion, the downward load on the bar portion bends the beam down. The strain sensor outputs a signal corresponding to the load and the pressure is worked out. By separately preparing plural kinds of sleeve portions with different outer diameters, the thickness of an ejector pin can be arbitrarily set according to conditions.
