Скачать или смотреть Siemens NX Die Casting Mold Base | Part 6: Moving Housing Design

In Part 6 of our Parametric Mold Base series, we design the Moving Housing (Ejector Side Housing). This block is the backbone of the moving half, holding the inserts, ejector system, and guide components.

We go beyond simple extrusions to show you the real-world manufacturing details required for a professional mold base. This includes creating air vents to prevent compressed air pockets behind guide bushes and adding clearance reliefs for return pins to reduce friction.

🔥 Professional Details Covered:

Main Block Setup: Extruding the housing and creating the Insert Pocket (0.5mm proud).

Diffuser Lock: Creating the pocket and D-Lock for the Diffuser.

Guide Bush Pockets: Designing accurate pockets with Air Vents (a critical tip to prevent trapped air during assembly!).

Return Pin Holes: creating through-holes with a larger Relief Bore after 60mm to reduce friction and wear.

Ejector Guide Pillars: Creating the blind mounting pockets and M12 bolting for the pillars that guide the ejector grid.

Lifting & Mounting: Adding standard M36 Lifting Holes and M12 Guide Bush retaining bolts.

❓ Shop Floor Question: Do you always add Air Vents behind your Guide Bushes (like at 06:39)?

I've seen many designers forget this, causing the bush to "pop" out or be hard to install due to trapped air. What's your standard practice? 👇
