Method for manufacturing injection moulded plastics transport crates uses one mould having separate movable moulded corner members between wall members so that first one plastics is injected and solidifies before injecting second plastics

摘要

the method involves placing separate movable moulded corner members (3) between the moulded wall members (1,2) to make up the crate corners whereby a wall and/or corner member can be moved into a first position where a first plastics is injected and a second position where a second plastics is injected. The second injection process is carried out when the plastics of the first process has solidified. The corner members are enclosed on each side by two wedges (5) so that the walls and corners can bear against the side faces of same. Independent claim describes injection mould with moulding core surrounded on five sides by walls wherein separate movable corner members are placed between the walls and have wedges on either side.
