Abstract: A connector structure suitable for a high-frequency signal transmission is provided. The connector structure includes a printed circuit board for transferring and processing high-frequency signals, and being electrically connected to a transmission cable, so as to transmit the signals. Here the electrical connection between the ground line of the transmission cable and the ground line of the circuit board must be avoided, so as to prevent high-frequency electromagnetic wave noise from being sent out together with the signals. In addition, an electromagnetic wave insulated absorbing material covers the circuit board, for attenuating the high-frequency electromagnetic wave noises generated by the circuit board. Finally, the transmission cable and the circuit board covered by an electromagnetic wave insulated absorbing material are accommodated within a metal case, thereby reducing the conduction impedance between the shells of the metal case, so as to eliminate the electromagnetic interferences (EMI).

Abstract: A method for protecting a mold of a servo-driven type mold clamping unit comprises the steps of (a) changing the torque output of the power source generated by a servo-motor subject to the position of a movable die of the mold, and (b) comparing the values set in an encoder of the servo-motor with signal received by the encoder when the movable die is in displacement so as to detect the presence of any foreign objects in the mold for determination of normal/abnormal handling control.

Abstract: A back pressure control method of a servo-driven injection molding machine is proposed, wherein the injection molding machine includes a metering servo and an injection servo motor, which is controlled by a current circuit, a position circuit, a speed circuit and corresponding controllers thereof, so as to perform multi-stage metering control of back pressure. The back pressure control method includes the steps of: establishing a current-pressure relationship table according to mechanism design of the injection molding machine and torque values of the injection servo motor; setting a back pressure value and a rotation speed of the metering servo motor for each metering position; retrieving a current value corresponding to a maximal set value of back pressure according to the current-pressure relationship table, so as to obtain a torque upper-limit value outputted by the injection molding machine; and setting output from a position controller of the position circuit to be zero.

Abstract: The present invention provides a servo drive type automatic mold-adjusting control method. When a toggle of a mold-clamping unit of a servo drive type injection molding machine stretches straight, if a mobile moldboard exactly contacts a static moldboard, the mold-clamping force will be near zero at this time. Assume the toggle recedes a distance and a mold-adjusting board and the mobile moldboard move forwards another distance and are then fixed, if the toggle stretches straight at this time, the mobile moldboard cannot move forwards continually because it already contacts the static moldboard. Therefore, advance of the motor will result in deformation of tie bars, hence building the mold-locking force.
