Alignment Pin for Split-Mould Clamping Bush

Reusable, extractable dowel/alignment pin used to accurately align MB6 or MB8 Split-Mould Clamping Bushes during mould lamination using a tooling prepreg.

Patterns should be designed with holes machined into the pattern where the bushes will be located. Before laminating of the mould, mould bushes are slid onto the alignment pins which are then pushed into the positioning holes in the pattern. The alignment pins then hold the mould bushes securely and accurately in position whilst the mould is laminated using tooling prepreg, with the bushes encapsulated within the laminate.

Following initial cure, the alignment pins should extracted before the mould is separated from the pattern.

The pins have an M8 thread in their cap and can be extracted by T-handle, slide hammer or cordless drill:

• T-Handle Hex Driver: Lock an allen cap M8 screw to the pin using an M8 nut and twist the pin free using a T-handle hex driver.
• Slide Hammer: Attach a slide hammer to the pin using an M8 thread (a thread adapter might be required).
• Cordless Drill: The chuck of a cordless drill can be tightened over the head of the alignment pin to provide a steady rotation and lifting action though it may be preferable to ‘crack’ the bond first with a slide hammer or T-handle.

Following extraction, the alignment pins can be reused indefinitely whenever you need to set MB6/MB6 mould bushes.
