You can simulate the mold opening process by defining steps and moves in the mold model. • Define steps. • Define moves within steps. • Rules: – Each step can contain several moves. – Components can be in only one move per step. – A move may contain several members. Figure 1 – Fully …

You can create the molding by filling the mold cavity through the sprue, runners, and gates. • Molding parts: – Contain a Molding feature. – Are fully-functional parts. – Maintain a parent/child relationship with mold model components and features. • There can be only one molding part in the model. Figure 1 – Mold …

To save time, place user-defined features (UDFs) from your company’s UDF library into your model. • Open existing UDF (*.gph) • Select Placement references – Prompts can aid you • Edit Variable Dimensions and Annotations Elements • Options – Scaling – Dimension display – Redefine features on-the-fly • Adjustments – …

User-defined features (UDFs) save time by helping establish a library of commonly used geometry. • Define a UDF from a “template” model. – Standalone ♦ Reference Part option – Subordinate • Select features to include. – Must be sequential • Define prompts. – Every reference requires a prompt. • Define …

Ejector pin clearance holes are created in mold components so that ejector pins can pass through and push the molded part out. • Ejector pin holes are similar to conventional holes. – You can specify a different diameter through each intersected component. • Available types: – Linear – Radial – Coaxial – On Point …

You can create sprues, runners, and gates to channel molten plastic into the mold cavity. • Create sprues using sketch-based features. • Create runners and sometimes gates using the Runner feature. • Section shapes include: – Round – Half Round – Hexagon – Trapezoid – Round Trapezoid Creating Sprues Figure …

The waterlines check helps to ensure that the waterlines are not too close to the external surfaces of the mold model. • To perform a waterlines check, you must specify: – Part – Waterline – Minimum Clearance • Color-coded results: – Magenta — Areas within minimum clearance. – Green — Areas outside minimum clearance. …

You can apply optional end conditions to the waterline circuit segment endpoints. • The following end conditions can be applied: – None – Blind – Thru – Thru w/Cbore Figure 2 – Thru w/Cbore Waterline End Condition Analyzing Waterline End Conditions Figure 1 – Blind Waterline End Condition Figure 3 …

Waterlines are assembly-level features that you can use to create water channels in the mold model. • Specify the waterline circuit diameter. • Sketch the waterline circuit. – Section should contain only linear entities. • Specify the mold components to be cut. Figure 2 – Completed Waterline Creating Waterline Circuits Figure 1 – Sketching …

You can rename extracted mold components and apply start models to them. • Benefits of using templates: – Datums – Layers – Parameters – View Orientations • Because each mold component is a part model, it should be renamed accordingly. Figure 1 – Extracted Mold Component Model Tree Figure 2 – Renaming Mold Components …
