Abstract
Improvements to plastics injection machines incorporating a tubular body equipped on the outside with heating means, inside which there is a spindle (shaft) able to move linearly in an axial direction and able to rotate, to which is fixed, in the front region, a conical point with two diametrically opposed planar cuts (indentations) and which extends, in the rear region, in the form of two cylindrical sections, the smaller of them incorporating a threaded end for coupling it to the spindle, there being mounted on said smaller-diameter section a supplement and a guide ring with a plurality of axial holes arranged circumferentially and, on the larger-diameter cylindrical section, a valve which can be moved over it in an axial direction. The machines which incorporate these improvements are used for injecting preestablished amounts of plastics into a mould.
