[0030] In this embodiment, telescopic guide columns 15 are fixedly installed below and behind the first template 10 and the second template 11, a plurality of docking guide columns 18 are fixedly installed on the adjacent surfaces of the first template 10 and the second template 11, and a plurality of docking guide holes 19 that are matched and connected with the docking guide columns 18 are opened on the adjacent surfaces of the second template 11 and the first template 10. The docking guide columns 18 and the docking guide holes 19 are both located on the outside of the mold cavity 16. When the first template 10 and the second template 11 are merged, the two mold cavities 16 are merged and connected. The mold cavities 16 in the first template 10 and the second template 11 are used for the molding processing of elbow products.

[0031] In this embodiment, the rotating frame structure 6 includes a rotating mounting frame 7, a mounting collar 8 and a docking rod 9. The two rotating mounting frames 7 are movably mounted on adjacent sides of the two mounting ear seats 4, respectively. The mounting collar 8 is integrally formed at the end of the rotating mounting frame 7. The docking rod 9 is fixedly mounted between the two mounting collars 8. The docking rod 9 serves to connect the rotating mounting frames 7 on both sides.

[0032] In this embodiment, the rotating mounting frame 7 is arranged in a triangular shape, and the three groups of first templates 10 and second templates 11 are respectively located on the inner side of the end between the two rotating mounting frames 7. The mounting ring 8 is movably mounted on the outer side of the mounting column 13. The switching handles 5 are movably mounted on the opposite sides of the two mounting ear seats 4. The shaft of the switching handle 5 passes through the mounting ear seats 4 and is fixedly connected to the rotating mounting frame 7. The rotating mounting frame 7 is mounted on the outer side of the mounting column 13 through the mounting ring 8 to install the three groups of first templates 10 and second templates 11.

When the hydraulic drive cylinder 3 is running, there is a gap between the clamping plug 27 and the mounting column 13, which does not affect the rotation switching of the first template 10 and the second template 11.

[0035] In this embodiment, the positioning docking ring 17 is embedded in the interior of the joint module 20, the first template 10 and the second template 11. The positioning docking ring 17 is arranged in a semicircular shape. The joint modules 20 on both sides merge with the first template 10 and the second template 11. The positioning docking ring 17 is inserted into the joint module 20 to achieve the effect of accurately connecting with the first template 10 and the second template 11.

[0036] In this embodiment, mounting screws 22 are provided on the opposite sides of the joint module 20 and the first template 10 and the second template 11. The mounting screws 22 penetrate the joint module 20 and are threadedly connected with the first template 10 and the second template 11. The mounting screws 22 play the role of installing and fixing the joint module 20.

[0037] In this embodiment, the positioning structure 23 includes a mounting seat 24, a push-pull rod 25 and a positioning plug 26. The mounting seat 24 is fixedly installed on the inner bottom of the mounting frame 2, the push-pull rod 25 is movably installed on the inner side of the mounting seat 24, and the positioning plug 26 is threadedly installed on the upper end of the push-pull rod 25. The push-pull rod 25 has the effect of moving back and forth. The positioning plug 26 can be rotated and quickly separated from the push-pull rod 25 through a threaded installation, and then the positioning plugs 26 of different sizes can be replaced and rotated to be threadedly connected with the push-pull rod 25, so that the positioning plug 26 can adapt to the joint cavities 21 of different sizes and models for matching connection.

[0038] In this embodiment, the push-pull rod 25 moves back and forth around the mounting seat 24, and the positioning plug 26 is inserted into the joint module 20 and connected with the joint cavity 21. The push-pull rod 25 moves back and forth to connect and separate the positioning plug 26 with the joint module 20.

[0039] It should be noted that the present invention is an elbow mold. When in use, the base plate 1 plays a role of placing and fixing, the mounting frame 2 is an integral mounting part, the first template 10 and the second template 11 are used at the inner center of the mounting frame 2, and the operation of the hydraulic drive cylinders 3 on both sides drives the clamping plug 27 to be ejected, so that the clamping plug 27 is inserted into the merging pressure hole 14 in the mounting column 13, and then the first template 10 and the second template 11 are pushed to move, so that the first template 10 and the second template 11 move toward the center for merging, and the telescopic guide column 15 telescopic movement plays a role of moving and positioning, and at the same time, the docking guide column 18 is inserted into the docking guide hole 19 to play a role of merging and positioning the first template 10 and the second template 11, and finally the mold cavities 16 on both sides are merged, and at the same time, the joint cavities 21 of the joint modules 20 on both sides are also merged, and the elbow product is formed in the mold cavity 16 and the joint cavity 21 with the expansion strip. When the first template 10 and the second template 11 are separated, the elbow product falls from the first template 10 and the second template 11 for demoulding;

[0040] When different models of first templates 10 and second templates 11 are used, the rotating mounting frame 7 is driven to rotate by the switching handle 5, so that the rotating mounting frame 7 rotates between the two mounting ear seats 4, thereby switching the three ends of the rotating mounting frame 7, and then switching the positions of the three groups of first templates 10 and second templates 11, and switching the first templates 10 and second templates 11 to be used to the inner side of the mounting frame 2, thereby switching the three first templates 10 and second templates 11, and changing the first templates 10 and second templates 11 to be used;

[0041] After the first template 10 and the second template 11 are switched, the push-pull rod 25 is pushed forward so that the positioning plug 26 is inserted into the two joint modules 20 in front of the first template 10 and the second template 11, and is connected and sealed with the end of the joint cavity 21, so as to quickly position the switched first template 10 and the second template 11, and after the first template 10 and the second template 11 are separated, the push-pull rod 25 is pushed forward again, so that the positioning plug 26 can also eject the elbow products in the first template 10 and the second template 11, so as to realize the demoulding and use of the elbow products;

[0042] When the first template 10 and the second template 11 need to be replaced, when the first template 10 and the second template 11 on the rotating mounting frame 7 need to be replaced, the first template 10 and the second template 11 to be used at the rear are merged, and after the first template 10 and the second template 11 are merged, the mounting column 13 is removed from the mounting collar 8 on the rotating mounting frame 7, so that the first template 10 and the second template 11 can be quickly removed, and then the replaced first template 10 and the second template 11 are expanded again, so that the mounting column 13 is inserted into the mounting collar 8 on the rotating mounting frame 7, so that the first template 10 and the second template 11 can be quickly replaced;

[0043] When the connector module 20 needs to be replaced, the mounting screws 22 on the connector module 20 are removed, and the connector module 20 can be separated from the first template 10 and the second template 11. Then, connector modules 20 of different types are installed to dock with the first template 10 and the second template 11. The positioning docking ring 17 achieves the effect of accurately connecting the first template 10 and the second template 11 with the connector module 20. Then, the mounting screws 22 are tightened to fix it. This allows three groups of first templates 10 and second templates 11 of different types to be installed with connector modules 20 of different types for use when switching between them.
