<p>The invention relates to a device for injecting thermoplastic material in a liquid state into a mould cavity. A distributor (27) of thermoplastic material in a liquid state, supplying at least one injection nozzle (17), is arranged between a matrix (1), defining at least one mould cavity (4) into which at least one nozzle (17) flows, and a spring release (36), respectively with the aid of a front plate (50) and, preferably, a rear plate (51), of a flat-resting thermally insulating material, in a manner that is as continuous as possible, on a surface (that is as large as possible) of a front surface (26) of the distributor (27) and a rear surface (29) of the matrix (1), preferably on a surface (that is as large as possible) of the rear surface (34) of the distributor (27) and the front surface (37) of the spring release (36) respectively. The matrix (1) is stiffened counter to bending as a result of the stress applied by the injected thermoplastic material and it is possible to reduce the thickness thereof in addition to the length of each nozzle (17).</p> |
