[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 This utility model provides a technical solution: a quick mold changing auxiliary device for a left and right front sealing plate stamping die, including a support frame 1, a lifting hydraulic column 2, a stamping hydraulic column 1 3, a limiting frame 1 4, a front sealing plate die 5, a positioning hole 1 6, a positioning rod 1 7, a stamping hydraulic column 2 8, a limiting frame 2 9, a side sealing plate die 10, a positioning hole 2 11, a positioning rod 2 12, a traction frame 13, a side sealing strip 14, and an auxiliary connecting frame 15;

[0033] Among them, the support frame 1 is set as a rectangular support. The support frame 1 is the main connecting support of the stamping die. The side wall of the support frame 1 has an opening. The front sealing plate die 5 and the side sealing plate die 10 are installed in the opening of the side wall of the support frame 1. The front sealing plate die 5 and the side sealing plate die 10 are the stamping dies of the left and right front sealing plates.

[0034] The upper end of the support frame 1 has a cylindrical groove, and a lifting hydraulic column 2 is installed inside the cylindrical groove of the support frame 1. The openings on the sides of the support frame 1 are C-shaped, with two openings on the sides and one on the front. The side walls of the openings of the support frame 1 are respectively provided with a first stamping hydraulic column 3 and a second stamping hydraulic column 8. There are four second stamping hydraulic columns 8, arranged in groups of two, and the installation directions of the second stamping hydraulic columns 8 and the first stamping hydraulic columns 3 are perpendicular. There are two first stamping hydraulic columns 3, and the output end of the first stamping hydraulic column 3 is connected to a first limiting frame 4. The first limiting frame 4 contains... A front sealing plate mold 5 is engaged and connected. A positioning hole 6 is provided in the front sealing plate mold 5, and two positioning rods 7 penetrate the upper end of the front sealing plate mold 5. A limit frame 9 is installed at the output end of the stamping hydraulic column 8, and a side sealing plate mold 10 is engaged and connected in the limit frame 9. A positioning hole 11 is provided in the side sealing plate mold 10, and two positioning rods 12 penetrate the upper end of the side sealing plate mold 10. Two side sealing plate molds 10 are provided, and the side sealing plate molds 10 are arranged perpendicular to the front sealing plate mold 5. The installation direction of the two side sealing plate molds 10 and the front sealing plate mold 5 forms a C shape.

[0035] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the support frame 1 is placed on a pre-determined horizontal foundation next to the stamping equipment and is firmly fixed by means of anchor bolts to ensure that the support frame will not shake or shift during subsequent operation. The lifting hydraulic column 2 is installed in the cylindrical groove at the upper end of the support frame 1, ensuring that its installation position is accurate and the connection is firm. The stamping hydraulic column 1 3 and the stamping hydraulic column 2 8 are installed on the side wall of the opening of the support frame 1 respectively, and are connected to the hydraulic oil pipeline through pipes. The limit frame 1 4 is reliably connected to the output end of the stamping hydraulic column 1 3, and the limit frame 2 9 is connected to the output end of the stamping hydraulic column 2 8. The front sealing plate mold 5 is fixedly installed and placed in the opening of the support frame 1 through the cooperation of the positioning rod 1 7 and the positioning hole 1 6, and the side sealing plate mold 10 is fixedly installed through the cooperation of the positioning rod 2 12 and the positioning hole 2 11.

[0036] The positioning hole 6 in the front sealing plate mold 5 is stably installed with the limit frame 4 by bolts, and the positioning hole 11 in the side sealing plate mold 10 is stably installed with the limit frame 9 by bolts. The stamping hydraulic column 3 and the stamping hydraulic column 8 are adjusted to push outward according to the working needs of the stamping mold, so as to facilitate the stamping of the left and right front sealing plates. Since there is a spring between the traction frame 13 and the side sealing strip 14, the spring can effectively buffer and maintain the stable connection between the traction frame 13 and the side sealing strip 14 during the process of the front sealing plate mold 5 driving the positioning rod 7 and the side sealing plate mold 10 driving the positioning rod 12 to move outward along the slide groove, thus ensuring the stability of the device operation.

[0037] The upper end of the lifting hydraulic column 2 is connected to the traction frame 13, and the upper end of the traction frame 13 is provided with a mounting frame that connects to the output end of the stamping equipment. Four auxiliary connecting frames 15 are evenly distributed on the upper end of the traction frame 13. The side wall of the traction frame 13 is engaged with the side sealing strip 14. The traction frame 13 is penetrated by the positioning rod 1 7 and the positioning rod 2 12. The traction frame 13 has a strip-shaped sliding groove, and each groove of the traction frame 13 is slidably connected to the positioning rod 1 7 or the positioning rod 2 12 respectively.

[0038] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the traction frame 13 is installed on the upper end of the lifting hydraulic column 2, ensuring a tight connection. An installation frame connected to the output end of the stamping equipment is installed on the upper end of the traction frame 13. At the same time, four evenly distributed auxiliary connecting frames 15 are installed. At this time, the side sealing strip 14 is snapped onto the side wall of the traction frame 13, so that the positioning rod 1 7 and the positioning rod 2 12 pass through the traction frame 13 and ensure that they can slide smoothly in the strip groove inside the traction frame 13.

[0039] When it is necessary to change the mold, control the stamping hydraulic column 1 3 and stamping hydraulic column 2 8 to retract and reset, so that the limit frame 1 4 and limit frame 2 9 release the locking restriction on the front sealing plate mold 5 and the side sealing plate mold 10. Operate the lifting hydraulic column 2 to lift, which drives the traction frame 13 and the internal positioning rod 1 7 and positioning rod 2 12 to rise, so that the used front sealing plate mold 5 and side sealing plate mold 10 move upward a certain height away from the opening position of the bearing frame 1, which is convenient for subsequent hoisting.

[0040] New front sealing plate mold 5 and side sealing plate mold 10 are hoisted from the mold storage area to above the opening of the support frame 1. The new front sealing plate mold 5 and side sealing plate mold 10 are stabilized by the cooperation of positioning rod 1 7 and positioning rod 2 12. The lifting hydraulic column 2 is operated to lower and send the new mold to the appropriate position in the limiting frame 1 4 and limiting frame 2 9, thereby fixing it in the appropriate position in the opening of the support frame 1. The stamping hydraulic column 1 3 and stamping hydraulic column 2 8 are started again to push the limiting frame 1 4 and limiting frame 2 9 respectively, and the front sealing plate mold 5 and side sealing plate mold 10 are firmly locked together, completing the mold installation. Then, the entire device is moved to the working position of the stamping equipment through the hydraulic equipment connected by the traction frame 13, ensuring that the mounting frame is accurately docked and firmly connected to the output end of the stamping equipment, and completing the quick mold change operation.

[0041] Working principle: When using the quick mold change auxiliary device for the stamping mold of the left and right front sealing plates, the support frame 1 serves as the basic support structure. Its C-shaped opening is used to place the front sealing plate mold 5 and the side sealing plate mold 10. The front sealing plate mold 5 is quickly positioned in the limiting frame 4 through the positioning hole 16 and the two positioning rods 17. The side sealing plate mold 10 is quickly positioned in the limiting frame 29 through the positioning hole 211 and the two positioning rods 22. There are two stamping hydraulic columns 3. After starting, their output ends push the limiting frame 14 to securely lock the front sealing plate mold 5 into the opening on the side wall of the support frame 1.

[0042] After the stamping hydraulic column 28 is started, its output end pushes the limit frame 29. At this time, the side sealing plate mold 10 is firmly locked in the side wall opening of the bearing frame 1, completing the installation of the mold on the bearing frame 1.

[0043] The lifting hydraulic column 2 is installed in the cylindrical groove at the upper end of the support frame 1. When the lifting hydraulic column 2 is started, it pushes the traction frame 13 to rise or fall. The mounting frame at the upper end of the traction frame 13 is used to connect with the output end of the stamping equipment. The four evenly distributed auxiliary connecting frames 15 can help enhance the connection stability.

[0044] Positioning rod 1 7 and positioning rod 2 12 pass through the traction frame 13 and are slidably connected to the strip groove inside the traction frame 13, thereby assisting the mold to move in the groove to realize the stamping operation. During the lifting process, positioning rod 1 7 and positioning rod 2 12 can move up and down in the groove to ensure the positioning accuracy of the mold when it moves in the vertical direction to change the mold.

[0045] When mold replacement is required, the first and second stamping hydraulic columns 3 and 8 are retracted and reset, causing the first and second limit frames 4 and 9 to release their engagement with the front sealing plate mold 5 and the side sealing plate mold 10. The lifting hydraulic column 2 is then raised to move the used front sealing plate mold 5 and side sealing plate mold 10 upwards. New front sealing plate mold 5 and side sealing plate mold 10 are then placed in, and the positioning rods 7 and 12 are used to fix the front sealing plate mold 5 and side sealing plate mold 10 in position. The lifting hydraulic column 2 is then lowered to send the new mold into the first and second limit frames 4 and 9. Finally, the entire assembly is inserted into the working position of the stamping equipment through the hydraulic equipment connected by the traction frame 13, thus completing the rapid mold change and increasing the overall practicality.

[0046] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
