About Mold Base Patterns
The EMX mold base assembly is controlled by patterns which are defined inside the skeleton model.
These patterns are manipulated by the Mold Base Definition dialog box.
Usually the number and dimensions of the patterns are defined based on the supplier mold base data. Still it can be useful to manipulate these values, for example, in case additional guide or screw instances are necessary.
* 
Modifying the standard patterns value may lead to geometry that does not fit the supplier standard.
The skeleton patterns define the position of the cutouts and the position of components assembled by the Mold Base Definition dialog box.
* 
Even if components are not defined using the Mold Base Definition dialog box, it is recommended to use the datums of these patterns as placement reference.
In the skeleton model, the following guide patterns are available:
• MAIN_GUIDE1 — Position of all main guide components and related cutouts on the first pattern scheme. Displayed in the top view and summary tree with .
• MAIN_GUIDE2 — Position of all main guide components and related cutouts on the second pattern scheme. Displayed in the top view and summary tree with .
• MAIN_GUIDE3 — Position of all main guide components and related cutouts on the third pattern scheme. Displayed in the top view and summary tree with .
• MAIN_GUIDE4 — Position of all main guide components and related cutouts on the 4th pattern scheme. Displayed in the top view and summary tree with .
• EJP_GUIDE — Position of guide components on the ejector package and related cutouts on the moving half.
• EJP_GUIDE_IS — Position of guide components on the ejector package and related cutouts on the fixed half.
In addition to the guide patterns, the following patterns are available:
• CLP_BORE_ES — Position of main clamping screws and related cutouts on the moving half.
• CLP_BORE_IS — Position of main clamping screws and related cutouts on the fixed half.
• EJP_BORE — Position of ejector package clamping screws and related cutouts on the moving half.
• EJP_BORE_IS — Position of ejector package clamping screws and related cutouts on the fixed half.
• STOP_BORE_IS — Position of stop system and the related cutouts on the fixed half.
• RAIL_SCREW — Position of rail screw and the related cutouts.
• RAIL_PIN — Position of rail dowel pin and the related cutouts.
• RETURN_PIN — Position of return pins and the related cutouts on the moving half.
• STOP_BORE— Position of stop system and the related cutouts on the moving half
• STOP_BORE_IS — Position of stop system and the related cutouts on the fixed half.
• INTERLOCK — Coordinate system pattern for the position of the side interlock assemblies.
• TOPLOCK — Coordinate system pattern for the position of the top interlock assemblies.
Switch the display to top view to view and modify the patterns.
1. In the Mold Base Definition dialog box, click Top to switch to the top view. The summary tree lists the number of patterns and the dimensions of the pattern.
2. Click MH and FH to view the mold base assembly patterns either from the bottom or from top.
3. Double-click the pattern either in the top view or from the pattern list. The relevant pattern dialog box opens.
4. Modify values for Quantity and Pattern Size along the x-axis and y-axis from the mold base origin.
5. Click to manually recalculate the pattern.
* 
Select the Automatically Recalculate check box to automatically recalculate the pattern when the parameters are updated.
6. Double-click a cell in the pattern table to modify the value.
7. Click or to show or hide the patterns in the preview window.
* 
For Main Guide 1 pattern, click to automatically create a guide component setup which has one instance on the first main guide component pattern and three instances on the second main guide component. This setup is used to assemble guide components with different inner diameters to avoid incorrectly rotated assembly of the mold base.
8. Click OK to close the dialog box, to update the assembly and to return to the Mold Base Definition dialog box, or click Cancel to close the dialog box, and to return to the Mold Base Definition dialog box.
