Abstract
Description
Technical Field
[0001] The utility model relates to an injection molding machine, in particular to an injection molding machine with a two-color to single-color balance fixture. Background Art
[0002] The two-color injection molding machine mainly includes a frame, on which two barrels, a fixed plate, a moving plate and an oil cylinder are arranged. A turntable is arranged on the fixed plate, and two sets of injection molds are arranged between the turntable and the moving plate. Each barrel corresponds to the glue inlet of a set of injection mold respectively. After the molten glue in the barrel is injected into the corresponding injection mold, after the glue cools and solidifies, the mold is opened, and the fixed mold of the injection mold is driven by the turntable to rotate, so that the two fixed molds exchange positions with each other, and then the mold is closed again, and the second kind of glue is injected, so as to manufacture plastic products of two different colors or two different materials. In actual production, if the two-color injection molding machine is to be changed into a single-color injection molding machine, one set of injection mold needs to be removed, or the original two sets of injection molds need to be removed and a new set of injection mold is placed. The position of one of the removed injection molds will be vacated. If the mold is directly closed for injection molding, when the oil cylinder drives the moving plate and the moving mold to close the mold, the vacated position cannot support the moving plate. Due to the large thrust of the oil cylinder, the moving plate will tilt towards the vacated side. After a long time of use, the moving plate and the guide post are prone to deformation and even scrapping. The existing method is usually to directly set a cushion block with the same height as the injection mold at the vacated position, but the structure of the cushion block cannot be adjusted. If other injection molds with different heights are replaced on this injection molding machine, the corresponding height cushion blocks need to be replaced, resulting in increased manufacturing costs, troublesome cushion block replacement, poor versatility, and if there is no corresponding cushion block, the injection molding machine will be idle. Summary of the Invention

[0011] The utility model relates to an injection molding machine with a two-color to single-color balance fixture, as Figure 1 — Figure 3As shown in the figure, it includes a machine platform 1, on which a barrel 2, a fixed plate 3, a moving plate 4 and an oil cylinder 5 are arranged. Guide columns 6 are arranged between the fixed plate 3 and the moving plate 4. A turntable 20 is arranged on the fixed plate 3. A set of injection molds is arranged between the turntable 20 and the moving plate 4. The injection molds are composed of a fixed mold 7 and a movable mold 8. One side of the fixed mold 7 is fixed to the turntable 20, and one side of the movable mold 8 is fixed to the moving plate 4. The barrel 2 has an injection port, which corresponds to the fixed mold 7. The piston rod of the oil cylinder 5 is connected to the moving plate 4. A balance jig is arranged on the side of the turntable 20 close to the moving plate 4. The balance jig includes a bottom plate 9, one side of the bottom plate 9 is fixed to the turntable 20. A first fixing column 10 is arranged on the bottom plate 9. A threaded hole 11 is made in the first fixing column 10. A stud 12 is arranged in the threaded hole 11. One end of the stud 12 is in threaded cooperation with the threaded hole 11. The other end of the stud 12 is made with a rotating column 13. The other end of the rotating column 13 is made with a plug column 14. The plug column 14 is connected to a second fixing column 15. A jack 16 is made in the second fixing column 15. The plug column 14 is inserted into the jack 16. A top plate 17 is arranged on the other side of the second fixing column 15. When the moving plate 4 drives the injection molds to close, the moving plate 4 contacts the top plate 17.
[0012] Furthermore, a rotating hole 18 is made in the rotating column 13. Tools such as a plug rod and a plug pin can be inserted into the rotating hole 18 and driven to rotate, so as to realize the rotation of the rotating column 13.
