Installation for producing structural parts made of a thermoplastic material for motor vehicles

A plant for manufacturing structural components made of a thermoplastic, especially for motor vehicles, comprising means (1) for the continuous production of a thermoplastic dough, means (8) for the accumulation and temporary storage of the dough produced and means (15) for the removal of the dough from the accumulation and temporary storage means and for the introduction of this removed dough into a first component-forming mold, comprising thermoregulated means in the form of a syringe having at least one dough charging/discharging orifice, these being carried by handling means (21) and being able to move between a dough-charging first position, in which the dough charging/discharging orifice of the means in the form of a syringe is connected to the outlet of the dough accumulation and temporary storage means (8) in order to allow transfer of the dough from these accumulation and temporary storage means into the means in the form of a syringe, and a second position for introducing the dough with which these means have been charged into the first mold, characterized in that the outlet of the accumulation and storage means (8) has a directional control device (12) which has at least two outlets (13, 14) and can be controlled so as to deliver the dough to one or other of them, one (13) of the outlets being designed to be coupled to the charging/discharging orifice of the thermoregulated means (15) in the form of a syringe and the other outlet (14) being designed to be coupled permanently to the charging orifice of a ram (16) for injecting dough under high pressure into a second component-forming mold (17), an outlet orifice (19) of which is designed to be coupled permanently to this second mold.
