Why a Nested Slider Was Chosen | Two-Stage Core Pull Design

This video explains the engineering decision behind a nested slider core-pull mechanism used to release a complex undercut. Instead of using a single large slider or a direct long-stroke core pull, this design applies a staged motion sequence to control the demolding process and reduce stress on the part. Mold configuration • Single-cavity (1+1) layout • YUDO direct hot-tip gating system • All standard components follow the HASCO system Core-pull sequence The mechanism uses a slider-driven-by-slider structure. Stage 1 A small primary slider moves first to release the local undercut. Stage 2 A hydraulic cylinder drives the main slider, which carries the small slider forward to complete the full core-pull stroke. Engineering intention This staged motion strategy allows: • Controlled release of complex undercuts • Reduced stress during demolding • More compact mold layout • Improved long-term mold stability This is not about adding complexity. It is about applying the right motion, at the right time, based on manufacturing reality. This is a design judgment based on manufacturing reality, not just theoretical feasibility. Motion-based mold design is not about animation — it’s about validating every movement before steel cutting. –––––––––––––––––––––––––– Engineering Support for Injection Mold Design (EU / US / International Projects) • Design-for-Manufacturing (DFM) review before steel cutting • Motion-based mold design for complex mechanisms • Clear 3D mold structures with engineering intent Contact: moldevo.design@gmail.com –––––––––––––––––––––––––– #InjectionMolding #MoldDesign #DFM #ToolingEngineering #Moldevo
