Abstract: An injection compression moulding apparatus comprises two mould parts (32, 36) which define a mould cavity and are mounted on two relatively movable platens (40) of an injection moulding press. An actuator (44) is arranged in series with the platen 40 acting on at least one of the mould parts (36) and is controlled in synchronism with the movement of the platens to enable the relative speed of the two mould parts (32, 36) during a mould closing phase of each article moulding cycle to be modified, the speed of relative movement of the mould parts being the vector sum of the speeds of movement and the platens (40) and the actuator (44).

Abstract: A mould is described for injection compression moulding of an article. The mould comprises two mould parts (14) and (16) mounted on two relatively movable platens (12) and (10) of an injection moulding machine and defining between them a cavity. A first mould part (14) is supported on a first (12) of the two platens in such a manner that it is capable of tilting out of parallel with the first platen (12). The first mould part (14) is rigidly connected to at least one axially extending support bar (24) which engages at its first end with a guide surface (28) mounted in fixed relation to the first platen and which slidably engages at its second end with a guide surface (26) mounted in fixed relation to the second platen, whereby in the closing stages of the mould, the weight of the first mould part (14) is carried by the support bar (24) while resting on both platens.

Abstract: A method is described for moulding a plastics article having a non-circular base. The method comprises the steps of providing a mould cavity (30) of the same shape as the article between relatively movable parts of a mould (16), applying a first force to close the mould, injecting into the base of the mould cavity a predetermined dose of plastics material sufficient to form the finish formed article, the injection pressure being sufficient to cause the mould parts to separate against the action of the applied first force whereby the injected dose of plastics material spreads to cover the entire area of the base of the cavity, and applying a greater second force to close the mould cavity fully by moving the mould parts further relative to one another, the second force being sufficient to cause the injected plastics material to flow into wall sections of the mould extending from the perimeter of the non-circular base.
