Abstract

A tool for use in a moulding machine suited to introducing plastic material under pressure into the mould, comprises a two part mould defining a mould cavity, the mould cavity including a recess 4 formed in one of the parts 1. The other part 2 closes the recess in use and has slidably mounted therein at least one support member 17 for supporting an insert 6 in the mould cavity. The or each support member being moveable between a first position in which the member projects into the mould cavity to support the insert at the commencement of a moulding operation and a second position in which the member is at least partially retracted from the mould cavity to disengage from the insert. Thus when material is introduced into the mould cavity the or each support member is urged from the first to the second position by pressure of the material after the insert has been enveloped in the material. <IMAGE>
