摘要： A preplasticizing type injection apparatus comprising an injection cylinder (12) internally provided with an injection plunger (10) and a plasticizing cylinder (22) provided in the inside with a plasticizing screw (20) or plunger, said injection and plasticizing cylinders (12,22) being arranged in juxtaposition and held in communication with each other by way of a resin conduit (3) connecting an inlet path (15) of the injection cylinder (12) arranged at the front end thereof and defining the limit of advancement of the plunger (10) and an outlet path (21) of the plasticizing cylinder (22) arranged at the front end thereof so that a front end portion of the injection cylinder (12) is charged with resin molten in the plasticizing cylinder (22) and the resin in the front end portion of the injection cylinder (12) is injected into a mold by means of the plunger (10), characterized in that the resin conduit (3) is realized in the form of a small metal pipe having an inner diameter between 5 and 10 mm and a length at least five times and preferably twenty to forty times greater than the inner diameter of the pipe and provided on the outer periphery with temperature control means (31) is provided. With such a conduit (3), resin passing therethrough can be more kneaded to improve the distribution of heat and plasticity before it gets to the injection cylinder (12).

摘要： A method and an apparatus for automatically exchanging a stamper unit (9) with another one for an injection molding machine (2) which is operated for injection-molding a disc or the like. The automatic exchanging apparatus (1) substantially comprises a case conveyance section and a stamper unit infeed/outfeed section wherein the case conveyance section includes a slide table (11) adapted to move in the longitudinal direction with the aid of a driving unit mounted on a housing (10), a pair of inside and outside conveyance platforms (12,13) each adapted to be raised up and lowered and a preheating member (14) arranged sidward of the inside conveyance platform (12) with the vertical attitude, while the stamper unit infeed/outfeed section includes an infeed/outfeed path (31) arranged at the fore end part of a driving unit mounted on a platform (7) at the upper part of a frame (4) upwardly extending from a housing (10) and an infeed/outfeed unit (38) arranged behind a suspension unit (32) for provisionally suspending a unit case (8), the suspension unit (32) being located at the rear part of the infeed/outfeed path (31). The automatic exchanging method is practiced by way of steps of alternately raising up and lowering the inside and outside conveyance platforms (12,13) in the conveyance section, temporarily holding each unit case (8) in the infeed/outfeed section and displacing the infeed/outfeed unit (38) in the forward/rearward direction so as to allow a used stamper unit (9) to be exchanged with a new preheated stamper unit.
