Die cast mould apparatus

A mould apparatus comprising:

• a first part for supporting a first mould body portion;
• a second part for supporting a second mould body portion said second part moveable toward said first part along a first path such that said first and second mould body portions form a mould body partially defining a mould cavity;
• a retainer for supporting a mould body insert in extending relationship therefrom;
• said mould body insert for association with said partially defined mould cavity, to further define said mould cavity;
• said retainer slidably mounted on a support for movement along a second path between a first position whereat said insert is substantially removed from said partially defined mould cavity and a second position whereat said insert is within said partially defined mould cavity to further define said mould cavity;
• interlocking means comprising
• a first one of a wedge receptor in said retainer and a slidable wedge supported by said retainer, and
• a first complementary one of a wedge receptor in said support and a slidable wedge supported by said support;
• and
• camming means interconnecting said retainer and said first wedge for extending said first wedge toward and into said first wedge receptor as said retainer is moved from said first position to said second position such that said first wedge engages said first wedge receptor when said retainer is in said second position to lock said retainer in said second position.

A die cast mould apparatus comprising:

• a base for supporting a mould body, said mould body partially defining a mould cavity;
• a mould body insert to further define said mould cavity when said mould body insert is inserted in a partially defined mould cavity and locked in a position,
• said mould body insert mounted on a retainer;
• a support extending from said base defining a channel wherein said retainer is locked to said support in said channel by way of interlocking wedges and wedge receptors when said retainer is moved in said channel to further define said mould cavity;
• and
• wherein one of said wedges and wedge receptors is on said retainer, and the other one of said wedges and wedge receptors is on walls of said channel.
