7. The length of the guide groove is too small
Due to the limitation of the template area, the length of the guide groove is too small for some molds, and the slider is exposed outside the guide groove after the core pulling action is completed. This will easily cause the slider to tilt during the core pulling stage and the initial stage of mold resetting, especially during mold clamping. At this time, the sliding block is not reset smoothly, causing damage to the sliding block or even breaking under bending. According to experience, after the slider completes the core-pulling action, the length left in the chute should not be less than 2/3 of the full length of the guide groove.
