In a back pressure control apparatus for controlling back pressure in an injection molding machine comprising an injection device which comprises a heating cylinder, a screw, and an injection actuator and which is provided with a back pressure detector for producing a pressure detected signal and with a screw position detector for producing a screw position detected signal, the back pressure control apparatus comprises a level setting section for setting a back pressure control level with respect to back pressure. A sharpness selecting section selects, as a selected sharpness, one of a plurality of sharpnesses in transition up to a maximum back pressure command value. On the basis of the back pressure control level, a determining section determines a back pressure pattern having a variable back pressure command value which continuously changes with respect to a retreat position of the screw. The back pressure pattern has a mountain-shaped portion defined by the selected sharpness. Responsive to the pressure detected signal and the screw position detected signal, a controller controls the back pressure in accordance with the back pressure pattern by means of the injection actuator.

Back pressure control for an injection molding machine

A back-flow prevention apparatus is composed of a screw and a platelike closing member. The screw includes at least a metering portion having a groove formed thereon for advancing a resin. The closing member is brought into an open position state by resin pressure which is developed behind the closing member in association with metering, thereby establishing communication between the groove and a space located ahead of the screw. The closing member is brought into a closed position by a restoring force of an elastic material, thereby shutting off communication between the groove and the space located ahead of the screw. Upon completion of a metering step, the restoring force brings the closed position into the closing state to thereby shut off communication between the groove and the space located ahead of the screw. Accordingly, sealing can be completed before the start of an injection step. Further, since timing for shutting off communication between the groove and the space located ahead of the screw does not vary, not only can the amount of resin charged into a mold cavity be stabilized, but also variation in injection peak pressure can be suppressed. As a result, molded products can be prevented from suffering burrs, short shot, or like defects. Also, variation in weight among molded products can be suppressed.

Back flow-prevention apparatus

A method for ejecting a molded product from a die. The method includes advancing an ejector pin from a withdrawn position to a projected position for ejecting a molded product and withdrawing the ejector pin from the projected position to the withdrawn position. At a preset range in at least one of the advancing step and the withdrawing step, the ejector pin undergoes very small reciprocating movements having a period less than 0.1 seconds. When the ejector pin is advanced while very small reciprocation is performed over a preset range in the advancing step, energy due to the projection of the ejector pin is continuously and gradually dissipated. When the ejector pin is withdrawn while very small reciprocation is performed over a preset range in the withdrawing step, the molded product is easily separated from the ejector pin. Accordingly, scattering of molded products and generation of cracks in the molded products can be prevented. Also, the molded product is prevented from being placed back into the cavity. Further, a dwell step may be provided in which the ejector pin is maintained at its projected position while being subjected to very small reciprocation having a period shorter than 0.1 seconds.

A pressure sensor detects a clamping pressure applied by the driving source and produces a pressure detection signal. A control unit controls the driving source to adjust the platen interval and the clamping pressure through a plurality of steps in response to the distance detection signal and the pressure detection signal.

According to this method, it is possible to control the injection molding operation on the basis of a plurality of control parameters in accordance with characteristics demanded by the resin in the mold which varies time to time, thus making it possible to maximize the packing degree while minimizing burrs and short shot.
