Hydraulic forming die frame opening and closing holding mechanism

Abstract

This utility model relates to the field of license plate production technology and discloses a hydraulic forming mold frame opening and closing holding mechanism for license plates. It includes slide rails installed on both sides of a press, with sliders slidably connected to the slide rails. A support plate is fixedly connected to the top of the slider, and a column is fixedly connected to the top of the support plate. A crossbeam is installed at the upper end between the two columns, and an electromagnet is fixedly connected to the side of the crossbeam away from the press. In this hydraulic forming mold frame opening and closing holding mechanism, after the mold frame is opened, the opened portion rests against the crossbeam. At this time, the electromagnet on the crossbeam is activated. Since the mold frame is made of metal, the opened portion is firmly attracted and fixed to the crossbeam by the electromagnet until a robotic arm places the required letter mold into the mold frame. The electromagnet then closes, and the mold frame closes automatically under its own weight, facilitating subsequent letter pressing operations by the press.

Description

Technical Field

[0001] This utility model relates to the field of license plate production technology, specifically to a license plate hydraulic forming mold frame opening and closing holding mechanism. Background Technology

[0002] Traditional license plate production is primarily manual, with the lettering process being particularly reliant on manpower. During operation, workers must first precisely embed the letter mold assembly into the corresponding cavity of the mold frame, ensuring the characters are arranged according to process specifications. Next, the mold frame is opened, and the semi-finished aluminum plate is placed stably in the designated area of ​​the mold cavity. The mold frame is then closed and secured, and the mold frame assembly is slowly pushed into the press platform, starting the equipment to complete the lettering. However, manual operation is inefficient. To increase production capacity, robotic arms are now widely used to replace manual labor, automating this process.

[0003] Since the robotic arm is only equipped with a single gripping mechanism, and the gripping of the character mold group needs to be completed by a fixture, this is fundamentally different from the manual operation where both hands can work together (one hand holds the mold frame open, and the other hand places the character mold). Currently, the robotic arm cannot keep the mold frame open while gripping the character mold, and the mold frame itself lacks a self-locking structure. When there is no external support, it will automatically close due to its own gravity, which makes it impossible to accurately place the character mold into the designated position in the mold cavity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a license plate hydraulic forming mold frame opening and closing retention mechanism, which allows the mold frame to always be in the open state.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a license plate hydraulic forming mold frame opening and closing holding mechanism, including slide rails installed on both sides of a press, a slider slidably connected on the slide rails, a support plate fixedly connected to the top of the slider, a column fixedly connected to the top of the support plate, a crossbeam installed at the upper end between the two columns, and an electromagnet fixedly connected to the side of the crossbeam away from the press.

[0006] Furthermore, both ends of the crossbeam are fixedly connected to fixing blocks, the top of the fixing blocks are fixedly connected to support plates, and the side walls of the column are provided with sliding grooves that match the fixing blocks.

[0007] Furthermore, a roller is provided below the crossbeam, and a rotating groove is provided at both ends of the roller. A rotating block is rotatably connected inside the rotating groove, and a positioning block is fixedly connected to the side of the rotating block away from the roller. The positioning block matches the sliding groove.

[0008] Furthermore, a limiting block is provided below the positioning block, the limiting block matches the slide groove, and the sum of the lengths of the limiting block, the positioning block, and the fixing block is equal to the length of the slide groove.

[0009] Furthermore, a through-beam photoelectric switch is provided at the upper end of the column on the side away from the press, and the through-beam photoelectric switch is fixedly connected to the column.

[0010] Furthermore, a bolt is threadedly connected to the middle position of the support plate away from the press, and the lower end of the bolt passes through the slider and abuts against the top of the slide rail.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this type of license plate hydraulic forming mold frame opening and closing holding mechanism, after the mold frame is opened, the opened part of the mold frame will rest against the crossbeam. At this time, the electromagnet on the crossbeam will be activated. Since the mold frame is made of metal, the opened part of the mold frame will be firmly attracted and fixed to the crossbeam by the electromagnet until the robot arm puts the required letter mold into the mold frame. Only then will the electromagnet close, and the mold frame will close automatically under its own gravity, thus facilitating the subsequent pressing operation of the press.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1-5A license plate hydraulic forming mold frame opening and closing holding mechanism includes slide rails 2 installed on both sides of press 1, sliders 3 slidably connected on slide rails 2, support plates 4 fixedly connected to the top of sliders 3, columns 5 fixedly connected to the top of support plates 4, crossbeams 8 installed at the upper end between the two columns 5, and electromagnets 11 fixedly connected to the side of crossbeams 8 away from press 1.

[0016] In this utility model, the license plate hydraulic forming mold frame opening and closing holding mechanism has the following mechanism: after the mold frame 18 is opened, the opened part of the mold frame 18 will rest against the crossbeam 8. At this time, the electromagnet 11 on the crossbeam 8 will be activated. Since the mold frame 18 is made of metal, the opened part of the mold frame 18 will be firmly attracted and fixed to the crossbeam 8 by the electromagnet 11 until the robot arm puts the required character mold into the mold frame 18. Then the electromagnet 11 will close, and the mold frame 18 will close by itself under its own gravity, thus facilitating the subsequent pressing operation of the press 1.

[0017] like Figure 2 , Figure 3 and Figure 4 As shown, both ends of the crossbeam 8 are fixedly connected to fixing blocks 9, the top of the fixing blocks 9 is fixedly connected to a support plate 10, and the side wall of the column 5 is provided with a sliding groove 6 that matches the fixing blocks 9.

[0018] Specifically, the crossbeam 8 is inserted between the two columns 5 by the fixing block 9, and the crossbeam 8 is held at the upper end of the two columns 5 by the support plate 10. This allows the electromagnet 11 to be kept away from the mold frame 18. So even if the electromagnet 11 is accidentally activated when the mold frame 18 is not open, it will not affect the mold frame 18.

[0019] like Figure 2 , Figure 3 and Figure 5 As shown, a roller 12 is provided below the crossbeam 8. Rotating grooves 13 are provided at both ends of the roller 12. A rotating block 14 is rotatably connected inside the rotating groove 13. A positioning block 15 is fixedly connected to the side of the rotating block 14 away from the roller 12. The positioning block 15 matches the slide groove 6.

[0020] Specifically, if the mold frame 18 becomes rusty and stuck due to prolonged use and remains in a vertical position, thus preventing the mold frame 18 from closing automatically after the electromagnet 11 is turned off, then when the mold frame 18 moves into the press 1, the roller 12 will press the open part of the mold frame 18 back, so that the angle between the open part of the mold frame 18 and the horizontal plane is less than 90°, thereby increasing the probability of the mold frame 18 closing automatically, and at the same time avoiding the mold frame 18 from colliding with the crossbeam 8, which would cause damage to the mold frame 18.

[0021] like Figure 2 and Figure 3As shown, a limiting block 7 is provided below the positioning block 15. The limiting block 7 matches the slide groove 6. The sum of the lengths of the limiting block 7, the positioning block 15, and the fixing block 9 is equal to the length of the slide groove 6.

[0022] Specifically, the positioning block 15 is restricted by the limiting block 7 to prevent the roller 12 from being too close to the worktable of the press 1, which would cause the mold frame 18 to be blocked by the roller 12 and unable to move.

[0023] like Figure 2 and Figure 3 As shown, a through-beam photoelectric switch 17 is provided on the upper end of the column 5 away from the press 1, and the through-beam photoelectric switch 17 is fixedly connected to the column 5.

[0024] Specifically, when the mold frame 18 is open, the through-beam photoelectric switch 17 will be blocked by the open part of the mold frame 18, while when the mold frame 18 is closed, the through-beam photoelectric switch 17 will not be blocked. Thus, the through-beam photoelectric switch 17 can be used to determine whether the mold frame 18 is closed.

[0025] like Figure 1 and Figure 3 As shown, a bolt 16 is threadedly connected to the middle position of the support plate 4 away from the press 1. The lower end of the bolt 16 passes through the slider 3 and abuts against the top of the slide rail 2.

[0026] Specifically, after the column 5 is slid to the appropriate position, the bolt 16 can be tightened to fix the support plate 4 and prevent the support plate 4 from shifting.

[0027] 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.
