Claims (7)

1. Способ горячей формовки изделий из термопластичного материала, включающий этапы: нагрева, по меньшей мере, одной пластины из термопластичного материала до температуры пластификации, и сжатия нагретой пластины между двумя формующими поверхностями, установленными одна против другой, пары половинок матрицы, отличающийся тем, что он включает этап формовки посредством литья под давлением, по меньшей мере, одной вставки, прикрепленной к поверхности пластины, при этом пластину подвергают сжатию между формующими поверхностями.1. A method of hot forming articles of thermoplastic material, comprising the steps of: heating at least one plate of thermoplastic material to a plasticization temperature, and compressing the heated plate between two forming surfaces installed one against the other, a pair of matrix halves, characterized in that it includes the step of molding by injection molding at least one insert attached to the surface of the plate, wherein the plate is compressed between the forming surfaces. 2. Способ по п.1, отличающийся тем, что литье под давлением вставки выполняют посредством впрыска пластмассы при высоком давлении в гнездо, связанное с одной из формующих поверхностей.2. The method according to claim 1, characterized in that the injection molding of the insert is performed by injection of plastic at high pressure into a socket associated with one of the forming surfaces. 3. Способ по п.2, отличающийся тем, что в гнезде выполняют суженную часть, предназначенную для получения снижения давления впрыскиваемой пластмассы при контакте с пластиной.3. The method according to claim 2, characterized in that the narrowed part is designed in the socket, designed to obtain a reduction in pressure of the injected plastic in contact with the plate. 4. Способ по п.1, отличающийся тем, что он включает этап перемещения ползуна, ограничивающего одну часть гнезда, для извлечения элемента, полученного литьем под давлением, из соответствующего гнезда.4. The method according to claim 1, characterized in that it includes the step of moving the slider, limiting one part of the socket, to remove the element obtained by injection molding from the corresponding socket. 5. Устройство для горячей формовки изделий из термопластичного материала, содержащее: первую половинку матрицы и вторую половинку матрицы, выполнены с возможностью перемещения одна относительно другой между открытым положением и закрытым положением, и снабжены соответствующими формующими поверхностями, предназначенными для осуществления горячей формовки, по меньшей мере, одной пластины из термопластичного материала, отличающееся тем, что, по меньшей мере, одна из половинок матрицы содержит, по меньшей мере, одно гнездо для литья под давлением, связанное с соответствующей получаемой горячей формовкой поверхностью, по меньшей мере, одним инжекционным каналом, предусмотренным для впрыска пластмассы внутрь гнезда.5. A device for hot forming articles of thermoplastic material, comprising: the first half of the matrix and the second half of the matrix, made with the possibility of moving one relative to another between the open position and the closed position, and provided with corresponding molding surfaces intended for hot forming, at least , one plate of thermoplastic material, characterized in that at least one of the halves of the matrix contains at least one socket for casting under a phenomenon associated with the corresponding obtained hot molding surface, at least one injection channel provided for the injection of plastic into the socket. 6. Устройство по п.5, отличающееся тем, что гнездо для литья под давлением имеет суженную часть, предназначенную для снижения давления впрыскиваемой пластмассы при контакте с пластиной.6. The device according to claim 5, characterized in that the socket for injection molding has a narrowed part, designed to reduce the pressure of the injected plastic in contact with the plate. 7. Устройство по п.5, отличающееся тем, что половинка матрицы, снабженная гнездом для литья под давлением, включает ползун, выполненный подвижным относительно половинки матрицы между рабочим положением, в котором ползун ограничивает часть гнезда для литья под давлением, и нерабочим положением, в котором вставка, полученная литьем под давлением извлекается из гнезда.7. The device according to claim 5, characterized in that the half of the matrix, equipped with a socket for injection molding, includes a slider made movable relative to the half of the matrix between the working position, in which the slider limits the part of the socket for injection molding, and the idle position, in wherein the injection molded insert is removed from the socket.
