[Previous technology] Plastic products are widely used in daily necessities. No matter what food, clothing, accommodation, and travel are required, its molding method is probably equipped with two compatible children: a matching mold. The system is fixed on the mold base, one of which is driven by the red pressure. When the mold is to be closed, the system starts the red pressure to push the red pressure shaft, and then drives the mold base and the mold to push out, for the plastic to be closed. ^ "Board", Tanaka molding "wait to be completed" and then start the cylinder; 1 cylinder shaft with the core seat, the mold is retracted to the position "However, the traditional setting of the pressure using the cylinder as the power source is not convenient, and The axial direction of the cylinder shaft is the same as the moving direction of the mold base. Therefore, when the plastic is molded and expanded in the mold, the 1-clamp flapping mold causes the cylinder shaft to be slightly retracted by the thrust, resulting in uncertain quality of the finished product. Therefore, it is necessary to improve the existing device that pushes the plastic mold in red. [New content] In order to improve the above defects, the main purpose of this creation is to provide a driving device that controls the opening and closing of plastic molds with accurate and stable strokes. < Based on the above purpose, the main technical means of this creation is to set a -servo motor 'on the side of the machine base, and the center of the machine base is provided with a lead screw for the servo motor to drive and rotate, and the lead screw is facing the inner mold base. The end protrudes, and a moving seat capable of moving the upper die seat is screwed on the guide M257273 screw. The moving seat stands up to the machine seat and is provided with a guide rod passing through the machine seat. Due to the above-mentioned technical means, when the closed-molding is controlled, the servo motor is started to drive the lead screw to rotate, so that the moving seat on the lead screw has less axial displacement than the lead screw. The end of the seat is pushed out: when the plastic is pushed against the inner mold seat, the moving seat is subjected to the pushing force; and the guide screw must be rotated to move the movable seat, while the guide screw is stationary because the servo motor is stationary The shape cannot be rotated, so the mold has a very high degree of closeness when it can be molded, which stabilizes the quality of the finished product. In addition, 'Because the servo motor is numerically controlled, & it is more convenient when it wants to adjust the speed'.
