What is slide in plastic injection molds making?<\/h1>\n\n\n\n

The slide in injection mold, also known as the lateral core extraction mechanism, is commonly used in injection molds making. When there is an undercut on the side of the product that is inconsistent with the ejection direction, a lateral core extraction mechanism must be designed. <\/p>\n\n\n\n

The principle is to first extract the buckle position and then eject the product, otherwise the product will be damaged. If there is a buckle position inside the product, due to space limitations, we will design an inclined ejector. Today we will share the types of sliders and design requirements.<\/p>\n\n\n\n

What is the basic components of a slide in injection mold?<\/h2>\n\n\n\n

A conventional slider is composed of a slider seat – a slider insert – a pressure plate – a shovel – an inclined guide column – a limit screw – a wear-resistant sheet – a spring, and each component has a corresponding function.<\/p>\n\n\n\n

When designing the slider, due to processing errors, in order to prevent interference between the shovel and the inclined guide column during movement, the shovel should be 2~3 degrees larger than the angle of the inclined guide column. <\/p>\n\n\n\n

For the convenience of processing, the angle range of the inclined guide column is generally between 15~25 degrees. If the angle of the inclined guide column is 15 degrees, then the angle of the shovel should be 17 degrees.<\/p>\n\n\n\n

Some positioning methods of slide in injection mold<\/h2>\n\n\n\n

1) Positioning with ball screws<\/h3>\n\n\n\n

The advantages are easy processing and simple operation; the disadvantage is that it is easy to damage. It is often used for small sliders in the X direction (horizontal) and sliders with large strokes. It can also help the slider to delay mold opening, because the ball will hold the slider against movement when the bevel is not working.<\/p>\n\n\n\n
