一种分体式滑块斜顶
By using a split-type slider angled ejector design, the slider is the first to disengage from the snap-fit and support ribs on the inside of the part, solving the problem of part tearing caused by the existing angled ejector structure, and achieving smooth demolding and quality assurance of the part.

AI Technical Summary
In the existing inclined ejector structure, during the ejection process, the clips and support ribs on the inside of the part are tightly adhered to the inclined ejector, resulting in tearing and quality problems.
A split-type slider and angled ejector are used. The slider is pre-moved to release the part from the snap-fit and support ribs inside, reducing the adhesion area. Then, the angled ejector is used for pushing and demolding.
This effectively prevents damage to the inner clips and support ribs of the parts during demolding, ensuring smooth demolding and high-quality finished products.
