Two-Step Bent-Pipe Core Pull (8 Sliders) | Automotive Mold Design Judgment

Motion-based mold design is not about animation — it’s about validating every movement before steel cutting. This video explains why this mechanism was chosen over a more traditional solution, based on real manufacturing risks. Project context • Automotive plastic part, 1 cavity (1C1) • DME metric standard components • Masters single sprue bushing → cold runner → fan gate Why two-step bent-pipe core pull A one-step pull often increases risk of: • Interference during opening • Galling / shut-off surface damage • Excessive slider load and unstable release Mechanism overview (8 sliders) Sliders are numbered #1 to #8 from the top-side view. Demolding sequence (engineering logic) 1.Mold opening (A/B separation) – Angle pins drive sliders #4, #5, and #8 for the first passive pull to create clearance. 2.Hydraulic pull – Stage 1 – Slider #1 is driven by a cylinder through a bent-pin linkage to pull the inner slider. – Sliders #2 and #6 are driven by a cylinder + linkage to complete the first bent-pipe pull. 3.Hydraulic pull – Stage 2 (key step) – Sliders #3 and #7 are driven by cylinders to push #2 and #6 for the second travel segment, ensuring full undercut release. The core idea is simple: split the bent-pipe release into two controlled steps to reduce risk and stabilize demolding. 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
