    摘要： A plasticizing unit and/or injection unit for a molding machine with an injection cylinder for plasticized material, at least one degassing opening, and a degassing device in flow connection with the at least one degassing opening for releasing and discharging undesired gases from the plasticized material. The degassing device has a flow element, in flow connection with the at least one degassing opening, which is formed to generate a negative pressure by the Venturi effect at the degassing opening, and/or the degassing device has a filter device, in flow connection with the at least one degassing opening, for filtering gases being released.

    摘要： Equipment is provided for the injection molding of thermoplastic materials containing high quantities of volatile substances which is of the type having a degassing zone constituted by the reduction at some point along the diameter of the core of the pressing screw, in registration with a vent hole adjacent the cylinder in which said screw moves. The particular improvement here involved is characterized by the provision, in combination with said degassing zone and preferably at a location immediately on the inlet side of the degassing zone itself, of a device shaped like a spinneret constituted by at least a plate provided with holes connected with the screw shaft and suitable for causing a high pressure on the thermoplastic material on the inlet side of said degassing zone and for increasing the surface of the thermoplastic material being subjected to said degassing. In addition, at least one part of the length of the cylinder containing said pressing screw is provided with a wide countersink or ovalization suitable for facilitating the advancing of the thermoplastic material through the equipment. Moreover, the said cylinder, starting from an end adjacent said vent-hole, is provided with a flared zone suitable to further facilitate the injection-molding operation.

    摘要： A kneading apparatus includes a plasticizing cylinder in which a high pressure kneading zone and a pressure reduction zone are formed adjacently in this order from an upstream side so that a molten resin obtained by plasticizing a thermoplastic resin and a pressurized fluid are kneaded with each other in the high pressure kneading zone, and gasified pressurized fluid, which is gasified by reducing a resin internal pressure, is separated in the pressure reduction zone from the molten resin kneaded with the pressurized fluid, a screw which is arranged rotatably and movably back and forth in the plasticizing cylinder; and a downstream side seal mechanism which is provided between the high pressure kneading zone and the pressure reduction zone and which makes communication and disconnection between the high pressure kneading zone and the pressure reduction zone in accordance with a rotation state of the screw.

    摘要： A plasticating apparatus adapted to handle a wide variety of synthetic resinous materials without predrying. The plasticating apparatus includes a two-stage screw rotatably and reciprocably mounted within a barrel. A surge suppressor is provided between the first and second stages and is comprised of an integral protrusion of the screw root and a deep channel section immediately preceding the protrusion. The surge suppressor prevents the surge of molten material into the vent area following the holding portion of an injection molding cycle, thereby allowing faster recovery and preventing bleeding of plasticized material from the vent opening.

    摘要： An injection molding machine having a vent opening on the heating barrel is disclosed which eliminates the clogging of the vent opening by the melt. This is attached by a step or steps in the size of the outer diameter of the screw and also steps in the size of the inner diameter of the barrel. The larger diameter portion of the barrel is located forwardly of the smaller diameter portion. The same is true of the screw. The vent opening is located in the portion of the device with a large barrel diameter but a small screw diameter.
