Injection molding machine with vertical plasticizing unit
View Patent ↗An injection molding machine includes a clamping unit constructed for support of at least two molding tools to provide at least two different cavities. A first plasticizing unit is provided for charging one of the cavities in one of the molding tools, and a second plasticizing unit is provided for charging the other one of the cavities in the other one of the molding tools. The second plasticizing unit is hereby attached to a mounting in a substantially vertical orientation. The mounting may be mounted on one of the platens of the injection molding machine or on a frame which extends above the clamping unit.
1. An injection molding machine, comprising:
a clamping unit having platens in axial spaced-apart relationship for support of molding tools in one to-one correspondence to provide at least two different cavities;
a first plasticizing unit constructed to convert plastic material into plastic melt for injection of plastic melt into one of the cavities;
a second plasticizing unit having a plasticizing cylinder and constructed to convert plastic material into plastic melt for injection of plastic melt into another one of the cavities;
a mounting received by one of the platens and carrying the second plasticizing unit in a vertical orientation, wherein the plasticizing cylinder of the second plasticizing unit is arranged at an axial distance to an outer end face of the clamping unit; and
a melt deflection device connected to the second plasticizing unit for deflection of plastic melt, produced by the second plasticizing unit, through the one platen and the molding tool supported thereon into the other one of the cavities.
2. The injection molding machine of claim 1 , further comprising an intermediate plate between the platens, with one of the molding tools being disposed between the intermediate plate and one of the platens, and the other one of the molding tools being disposed between the intermediate plate and the other one of the platens.
3. The injection molding machine of claim 2 , wherein the intermediate plate is constructed for movement in a linear direction and/or rotation.
4. The injection molding machine of claim 1 , wherein the second plasticizing unit is arranged on the mounting for up and down movements.
5. The injection molding machine of claim 1 , wherein one of the platens is fixed and the other one of the platens is mobile.
6. The injection molding machine of claim 1 , wherein the platens are mobile.
7. The injection molding machine of claim 1 , wherein the second plasticizing unit is positioned at an angle in a range of about 45° to 90° in relation to a horizontal.
