    The so-called slider is a mold component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action of the mold. When the product structure makes it impossible for the mold to be demolded normally without the use of the slider, the slider must be used.

    When the slider is opened, the inclined guide column drives the slider to move backwards. When the mold is closed, the inclined guide column drives the slider to move forward. When the side wall of the product has an inverted button and cannot be demolded, a slider mechanism can be used to facilitate the demoulding of the product. When the appearance of the product is high-gloss, and the surface quality is required to be high, it can also be used as a slider mechanism to facilitate molding.

    When the slider mechanism is large, in order to simplify the processing, save materials, and facilitate the replacement of the mold, the slider seat and the slider insert can be made separately, and then the slider insert is fixed on the slider seat with screws. When the slider is small, the slider seat and the slider insert can be directly made into a whole, which can reduce the processing process and one part.

    Slider bundle block

    The function of the slider bundle block is to resist the injection pressure and prevent the slider from retreating when the mold is closed. When the injection pressure is too large, the slider bundle block needs to be inserted into the male template. The slider bundle is used to tighten the slider seat, and at the same time, it can also prevent the burr from the broken surface of the slider.

    Slider block

    The function of this part is to press the part on the template beside the slider boss when the slider is placed in the template when the mold is matched, and form a guide groove with the slider boss, so that when the slider is formed, It can slide back and forth without falling out of the mold.

    Slide block wear block 

    When the mold is not being opened or closed, the slider will also move back and forth. During this movement, the sliding surface will continue to generate friction, and heat-treated wear blocks will be added to the sliding surface (the sliding surface needs to be Processing oil groove), which can greatly reduce the damage of friction to the template, and at the same time, it is easy to replace and adjust when the mold is closed, thereby prolonging the life of the mold.
