The insertion surface between the slider and the mold core must

  •   1. Design principle of Automotive mold slider

      (1) The inclination angle of the slider should be 2~3° larger than the inclination angle of the oblique guidepost, and the inclination angle of the oblique guidepost should not exceed 20°;

      (2) The distance between the sliding block and the sealing surface of the front mold should be greater than 15mm;

      (3) The insertion surface between the slider and the mold core must be made 3° or 5° to avoid direct friction with the automobile mold core;

      (4) It is best to keep the original shape of the shovel body, and the insertion form should ensure the strength;

      (5) The inclined surface and bottom surface of the slider need to be made of wear-resistant blocks, and fast molds can be considered without wear-resistant blocks;

      (6) The slider needs to add a spring (or a buckle, or a spring and a buckle together) and a limit device;

      (7) When the rubber surface area of ​​the slider is large, a backhoe is required;

      (8) Let it know how to calculate the stroke of the lower slider;

      (9) Know the material used for the wear-resistant block guide; whether it is necessary to open the oil groove; if necessary, open which side.
