Injection mold design process, here's my design experience and ideas to analyze with you:

The first step: product analysis and modification, to determine the mold structure, shrink map:

1.jpg

1, product analysis: mold opening direction, sub-mold line and sub-die surface, dimensions, thickness, draft angle, barb and the corresponding core pulling method, into the plastic point and the way into the plastic, the number of cavity and so on.

2, turn engineering: the use of three-dimensional software mapping, the general establishment of three views: the first main view (rear mold surface projection), the second third three-dimensional schematic (exterior and interior surfaces). The other views are laid out in the third angle method or the first corner method, the cross-sectional view (X and Y, the cut-off position line passing through the important position center, barbs, columns, holes, CAD opens the mark processing.


3, shrink map: The project will be a mirror image and zoom in a multiple of shrinkage. (Marked: MI, shrinkage)
