[0018] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a guide device for a press guide rail bracket, comprising: a positioning plate 5, a fixing plate 2 and a base 4, one side of the upper end of the base 4 is fixedly connected to the rear mounting plate 3, the upper end of the rear mounting plate 3 is fixedly connected to the fixing plate 2, the fixing plate 2, the rear mounting plate 3 and the base 4 are formed as one piece, and the structure is more stable. A guide column 13 is fixedly installed on one side of the rear mounting plate 3, and a positioning column 14 is fixedly installed on the lower end of the fixing plate 2. A hydraulic cylinder 1 is fixedly installed on the upper end of the fixing plate 2. The hydraulic cylinder 1 is a driving device, and the output end of the hydraulic cylinder 1 is fixedly connected to the positioning plate 5 through the fixing plate 2. The hydraulic cylinder 1 can make the positioning plate 5 generate a strong thrust. When the hydraulic cylinder 1 is started, the positioning plate 5 will perform vertical movement in the up and down directions.

[0020] When the mold 15 is in the mounting groove 7, the limiting plate 8 can be moved along the slide groove 12 and the guide rail 11 by rotating the threaded rod 9.

[0021] The positioning plate 5 is convex, and a positioning cylinder 6 is fixedly installed on the side of the positioning plate 5. The positioning cylinder 6 is sleeved with a guide column 13 or a positioning column 14. The positioning cylinder 6 can realize rapid guidance and rapid positioning of the positioning plate 5. A positioning cylinder 6 is fixedly installed on the tail end of the raised position of the positioning plate 5. This positioning cylinder 6 is sleeved on the surface of the guide column 13. When the positioning plate 5 moves up and down, under the action of this positioning cylinder 6, the positioning plate 5 will not tilt. The end of the guide column 13 away from the fixed plate 2 is fixedly connected to the upper end of the base 4. The other two positioning cylinders 6 are respectively located on both sides of the positioning plate 5. These two positioning cylinders 6 are respectively sleeved on the surfaces of the two positioning columns 14. The ends of the two positioning columns 14 away from the fixed plate 2 are welded to the upper end of the base 4. When the positioning plate 5 moves up and down, the positioning column 14 can prevent the positioning plate 5 from rotating and offsetting, so that the positioning plate 5 can move downward vertically stably.

[0022] When the device is working, after checking that the device is correct as a whole, the mold 15 is placed in the installation groove 7, and then the handle 10 is turned to make the threaded rod 9 rotate accordingly until the limit plate 8 firmly fixes the mold 15 in the installation groove 7. At this time, the hydraulic cylinder 1 is started, and the output end of the hydraulic cylinder 1 drives the positioning plate 5 to move downward. Under the action of the positioning column 14 and the guide column 13, the positioning plate 5 will fall vertically on the upper end of the mold 15 without any deviation, and the guidance is stable.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
