A brief introduction of slider and lifter in injection molding
Blog Article
In injection molding, sliding block and ejector mechanism are two commonly used mold auxiliary mechanisms, which are mainly used to solve the demoulding problem of complex structural parts.
Slider
effect
The slider is used to solve the demoulding problem after forming the lateral structure of the product (such as side hole, side concave, etc.).
Working principle
When the die is closed, the slider is locked under the action of the inclined guide post.
When the mold is opened, the inclined guide rod pushes the slider to move outwards, releasing the lateral structure and ensuring smooth demoulding.
peculiarity
Handle the lateral structure.
The direction of motion is usually horizontal or oblique.
Application scenario
Products with side holes, side clasps or other side geometric features.
Lifter
effect
The ejector mechanism is used to deal with the bottom cut or reverse structure in the product to assist the product demoulding.
Working principle
When the mold is opened, the thimble plate pushes the ejector mechanism, making it move up and offset in a certain direction to release the bottom cut.
After the thimble board is reset, the ejector mechanism returns.
peculiarity
Handle complex structures such as bottom cut and inner buckle.
Implement both ejection and offset actions.
Application scenario
Products with features such as inside clasps, grooves or bottom cuts.
Sum up
The slider is mainly used to solve the lateral problem, and the direction of movement is horizontal or oblique.
The ejector mechanism is used to handle bottom cuts or backdrops, combining ejector and offset functions.
The two are often used in combination for the design of high complexity injection parts to ensure the smooth release of the finished product.
