<p>An injection mould (20, 21) for containers (10) of plastic material; the container (10) comprises bottom and peripheral walls (11, 11') having an annular strip (12) along the upper rim, provided with two hollow lateral ears (13), at diametrically opposite positions, and a handle (14) having pins (15) pivotally engaged (15) to the same ears (13). The mould comprises a first mould half (20), having a circular cavity (22) that conforms to the bottom (11') and peripheral (11) walls of the container (10), and a second mould half (21) conformed with a protruding core (28) suitable for defining, with the circular cavity (22) of the first mould half (20), an injection chamber of the container (10). Two slides (29, 30), movable in a plane orthogonal to a longitudinal axis of the mould (20, 21), are shaped and cooperate with two fixed inserts (23) on the first mould half (20), in order to form the lateral ears (13); furthermore, one (30) of the two slides (29, 30) is provided with cylindrical members (32) suitable for forming holes (16) in the lateral ears (13) to pivotally engage the handle (14); the cylindrical members (32) are removable from one side, in the moving direction of the slide (30).</p> |
