An injection mould for making a bucket with a handle pivotally connected to the bucket by means of projections on the handle, said projections being in snap engagement with diametrally opposed openings in the bucket, said mould comprising a stationary mould half (20) and a movable mould half (21). The two mould halves (20,21) define a bucket mould cavity (27) corresponding to the shape of the bucket and handle mould cavity (29) corresponding to the shape of the handle and which in its entirety is radially external to the bucket mould cavity (27). The handle mould cavity (29) is externally defined by a movable mould member (34) in each of the portions corresponding to the projections. The mould member (34) is arranged on an arm (36) connected to an ejection plate (32). Further ejection pins (33) are connected to the ejection plate (32) for ejection of the handle. A driving means (44,46,47) is connected to the arm (36) and adapted to drive the mould member (34) with the handle (32) inwardly into engagement with the openings of the bucket when the ejection movement of the ejection plate (32) is completed.
An injection mould for making a bucket with a handle being pivotally connected to the bucket at two diametrically opposed portions thereof, each end of the handle being provided with a radial projection facing inwards and having an enlarged head snap-engaging an opening in an ear formed on the exterior of the bucket in each of the said diametrically opposed portions, said injection mould comprising a stationary mould half and a movable mould half axially displaceable in relation to each other between a closed and an open position and defining a handle mould cavity corresponding to the shape of the handle and a bucket mould cavity corresponding to the shape of the bucket, the stationary mould half having a female mould part so as to form the outer surface of the bucket and the movable mould half having a male mould part so as to form the inner surface of the bucket, wherein the handle mould cavity in its entirety is radially external to the bucket mould cavity, mould portions forming the projections of the handle being in the same axial plane as mould portions forming the openings of the bucket, but axially displaced towards the movable mould half, said movable mould half comprising an ejection plate having ejection pins extending to the handle mould cavity, and that in the portion corresponding to each of the projections the handle mould cavity is externally defined by a movable mould member arranged on an arm connected to the ejection plate, a driving means being attached to the arm to drive the mould member with the handle inwardly so as to bring the projections of the handle into engagement with the openings of the bucket ears when the ejection movement of the ejection plate is completed.
