Hello,
I have done some searching on the subject but have not found any good tutorials on creating/designing permanent patterns (gated, split etc). I am interested in learning how to create a permanent aluminum pattern to be used to create impressions in sand molds. My question is, using the 3D models of finished or cast components how then do I model a permanent pattern?
If anyone has any insight or helpful direction I would appreciate it.
Thank you
Flat parted patterns like this are easy. Once you have your pattern model with shrink and coreprint clearances all you have to do is split the body with a plane. Then you can draw the board that it mounts to and combine them. From there you can add the gating and locators.
If the pattern is not flat parted then typically you can model the parting as blocks that can be added or subtracted from the pattern plate.
I work for an aluminum foundry and we design all of our tooling in Solidworks. It can definitely be done without any other software. We design airset tooling, greensand tooling, permanent molds, low pressure permanent molds, shell coreboxes and SO2 coreboxes.
