Description

Technical Field

[0001] This application relates to the field of hot stamping machine equipment technology, and in particular to a frame for a quick-change electric cylinder hot stamping machine. Background Technology

[0002] In modern industrial production, hot stamping machines, with their unique technological characteristics, have become core equipment for achieving product surface decoration and labeling. They transfer hot stamping foil with specific patterns, text, or colors onto the product surface through heating and pressurization, thereby enhancing the product's aesthetics and added value. In the packaging industry, hot stamping machines can give gift boxes and labels a refined metallic texture or vibrant color effects; in the printing industry, they can achieve personalized decorations for book covers, greeting cards, etc.; and in leather processing, they are often used to create unique textures and brand logos. With their wide applicability and excellent decorative effects, hot stamping machines occupy an important position in many manufacturing industries, greatly satisfying the market's demand for diverse and high-quality product appearances.

[0003] Regarding the aforementioned technologies, the inventors believe that in the mold replacement process, traditional hot stamping machines mostly use bolt fastening or complex snap-fit ​​connections to fix the mold. Operators need to use various tools to disassemble a large number of parts in turn to complete the mold replacement. The whole process is not only time-consuming and labor-intensive, but also prone to inaccurate mold positioning due to installation errors. Therefore, a quick mold change electric cylinder hot stamping machine frame is proposed to solve the above problems.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the aforementioned issues, this application provides a frame for a quick-change electric cylinder hot stamping machine.

[0006] The quick-change electric cylinder hot stamping machine frame provided in this application adopts the following technical solution:

[0007] A quick-change electric cylinder hot stamping machine frame includes a frame, a worktable, a mold, and a mold changing assembly mounted on the worktable. The frame has a hot stamping machine body for hot stamping inside. A frame body is fixedly installed on the inner wall of the frame below the hot stamping machine body, and an inner groove is slidably connected to the outer wall of the frame body. The worktable is slidably connected to the inner groove. A drive assembly is provided between the worktable and the inner groove. The mold is located above the worktable.

[0008] The mold changing assembly includes a fixed base, which is fixedly connected to the outer wall of the worktable. A sliding column is fixedly connected to the inner wall of the fixed base, and a sliding sleeve is slidably connected to the outer wall of the sliding column. A movable seat is fixedly connected to the top outer wall of the sliding sleeve. The outer wall of the fixed base has multiple sliding grooves arranged in a circumferential array. A movable slider is slidably connected to the outer wall of each of the multiple sliding grooves. Multiple connecting rods are provided between the multiple movable sliders and the sliding sleeve, and the two ends of the multiple connecting rods are respectively hinged to the multiple movable sliders and the sliding sleeve. A fixing block is fixedly connected to the outer wall of each of the multiple movable sliders, and an installation block adapted to the multiple fixing blocks is fixedly connected to the bottom outer wall of the mold.

[0009] Preferably, the inner wall of the fixed base is slidably connected to two inclined moving plates, and the outer walls of the two sides of the sliding sleeve are symmetrically fixedly connected to two pulleys, and the two pulleys are slidably connected to the two inclined moving plates respectively. The outer walls of the two inclined moving plates are fixedly connected to connecting round rods, and the two connecting round rods slide through the fixed base and are installed with limit components. The outer walls of the connecting round rods are sleeved with spring members, and the two ends of the spring members are fixedly connected to the inclined moving plates and the fixed base respectively.

[0010] Preferably, the driving assembly includes a driving rod, the outer wall of the inner groove is rotatably connected to the driving rod, the outer side wall of the worktable is provided with a driving groove, and the outer wall of the driving groove is slidably connected to a driving sliding block, and one end of the driving rod is hinged to the driving sliding block.

[0011] Preferably, the limiting component includes an outer groove, which is formed on one side of the fixed base, and a limiting slider is slidably connected to the outer wall of the outer groove.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This device uses a mounting block at the bottom of the mold that corresponds to a fixed base. The mounting block moves the movable base downwards, causing the sliding sleeve to slide down the sliding column. The sliding sleeve then moves the fixed block inwards via a connecting rod, quickly engaging the fixed block with the mold and the mounting block. Similarly, the sliding sleeve moves upwards along the sliding column, quickly separating the fixed block from the mounting block on the mold. This enables rapid mold changing operations, facilitating operation and shortening mold changing time. Compared to traditional methods, it significantly improves mold changing efficiency and production efficiency.

[0015] 2. This device, through the coordinated operation of the drive rod, drive sliding block, and drive groove, can drive the worktable to move back and forth quickly, allowing the worktable to move rapidly to the outside. This facilitates mold changing for operators from the outside, improving mold changing efficiency. When the mold changing component is fixed to the mounting block, the mold changing component works in conjunction with the limiting component. Through the linkage of components such as pulleys, inclined plates, and connecting round rods, and in conjunction with the engagement of the limiting rod and the T-slot, the mold changing component is locked, improving mold stability.

[0024] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.

[0025] A quick-change electric cylinder hot stamping machine frame includes a frame 1, a worktable 9, a mold 7, and a mold changing component mounted on the worktable 9. The inside of the frame 1 is a hot stamping machine body 2 for hot stamping, which can perform hot stamping work on the mold 7. A frame body 3 is fixedly installed on the inner wall of the frame 1 below the hot stamping machine body 2, and an inner groove 4 is slidably connected to the outer wall of the frame body 3. The worktable 9 is slidably connected to the inner groove 4, and a drive component is provided between the worktable 9 and the inner groove 4. The drive component can drive the worktable 9 to move back and forth along the inner groove 4, thereby facilitating the operator to quickly change the mold 7 on the worktable 9. The mold 7 is located above the worktable 9.

[0026] The mold changing assembly includes a fixed base 8, which is fixedly connected to the outer wall of the worktable 9. A sliding column 17 is fixedly connected to the inner wall of the fixed base 8, and a sliding sleeve 16 is slidably connected to the outer wall of the sliding column 17. The sliding sleeve 16 is fitted onto the outer wall of the sliding column 17, allowing it to slide freely on the sliding column 17. A movable base 13 is fixedly connected to the top outer wall of the sliding sleeve 16. The outer wall of the fixed base 8 has multiple grooves 12 arranged in a circumferential array. Each groove 12 has a movable slider 14 slidably connected to its outer wall. The movable sliders 14 are respectively installed in the grooves 12, allowing them to slide within the grooves 12. Multiple connecting rods 15 are provided between the movable sliders 14 and the sliding sleeve 16, and the two ends of the connecting rods 15 are respectively hinged to the movable sliders 14 and the sliding sleeve 16. The two ends of the connecting rods 15 are respectively connected to the multiple movable sliders 14 and the sliding sleeve 16 through hinge shafts. Each movable slider 14 and sliding sleeve 16 is hinged to form a movable connection structure. The outer walls of each movable slider 14 are fixedly connected to a fixing block 19, and the bottom outer wall of the mold 7 is fixedly connected to an installation block 26 that matches the fixing blocks 19. After the installation block 26 of the mold 7 contacts the movable seat 13, the movable seat 13 is pushed to move downward. The movable seat 13 drives the sliding sleeve 16 to slide downward along the sliding column 17. The sliding sleeve 16 drives the fixing blocks 19 around it to move inward through the connecting rod 15 until the fixing blocks 19 engage with the installation block 26 of the mold 7, thus achieving the initial fixation of the mold 7. Then, the worktable 9 is moved to the hot stamping position through the drive assembly, which facilitates the hot stamping work of the hot stamping machine body 2. The mold 7 is quickly installed and fixed through the mold changing assembly, which greatly shortens the mold changing time and improves production efficiency.

[0027] Two inclined plates 20 are symmetrically slidably connected to the inner wall of the fixed base 8. Two pulleys 18 are symmetrically fixed to the outer walls of both sides of the sliding sleeve 16, and the two pulleys 18 are slidably connected to the two inclined plates 20 respectively. The outer walls of the two inclined plates 20 are fixedly connected to connecting round rods 21, and the two connecting round rods 21 slide through the fixed base 8 and are installed with limit components. The outer walls of the connecting round rods 21 are sleeved with springs 22, and the two ends of the springs 22 are fixedly connected to the inclined plates 20 and the fixed base 8 respectively. When the sliding sleeve 16 moves down, the pulleys 18 on both sides of the sliding sleeve 16 slide along the grooves on the inclined plates 20, causing the inclined plates 20 to retract into the fixed base 8. The inclined plates 20 drive the connecting round rods 21 to retract, and at the same time, the springs 22 are in a compressed state. The limit components then limit the springs, thereby ensuring the installation and fixation of the mold 7.

[0028] The drive assembly includes a drive rod 6, which is rotatably connected to the outer wall of the inner groove 4. A drive groove 11 is provided on the outer side wall of the worktable 9, and a drive sliding block 10 is slidably connected to the outer wall of the drive groove 11. One end of the drive rod 6 is hinged to the drive sliding block 10. After the servo motor 27 is started, its output shaft drives the drive rod 6 to rotate. The rotation of the drive rod 6 drives the drive sliding block 10 to slide along the drive groove 11. Since the drive sliding block 10 is connected to the worktable 9, it drives the worktable 9 to move along the inner groove 4, thereby realizing the horizontal position adjustment of the worktable 9 so as to change the mold 7 and switch the hot stamping work position.

[0029] The limiting component includes an outer groove 23, which is located on one side of the fixed base 8. A limiting slider 5 is slidably connected to the outer wall of the outer groove 23. The limiting slider 5 is fixedly connected to one end of the connecting round rod 21. A limiting rod 25 is rotatably connected to the outer side of the outer groove 23. A T-slot 24 is provided on the outer wall of the outer groove 23 on the side of the limiting rod 25. The outer groove 23 and the T-slot 24 are adapted to each other. When the inclined plate 20 drives the connecting round rod 21 to retract, causing the limiting slider 5 to slide to the side of the limiting rod 25, the operator rotates the limiting rod 25 to engage it in the T-slot 24. At this time, the limiting is achieved. The rod 25 blocks the limiting slider 5, restricting its movement and thus fixing the position of the inclined plate 20, ensuring the mold 7 is securely installed. When disassembling the mold 7, the limiting rod 25 is rotated to separate it from the T-slot 24, releasing the restriction on the limiting slider 5. This allows the inclined plate 20 to spring back under the action of the spring 22, achieving locking and unlocking of the inclined plate 20. The operation is simple and convenient, effectively preventing the mold 7 from loosening due to vibration and other factors during use. This improves the stability and reliability of the mold 7 installation and ensures the smooth progress of the hot stamping work.

[0030] A servo motor 27 is fixedly connected to the bottom outer wall of the frame 3, and the output shaft of the servo motor 27 is fixedly connected to the drive rod 6. The output shaft and the drive rod 6 are fixedly connected by a coupling or other means. When the worktable 9 needs to be moved, the servo motor 27 is started by the controller, and the rotation of the output shaft of the servo motor 27 drives the drive rod 6 to rotate.

[0031] The implementation principle of a quick mold-changing electric cylinder hot stamping machine frame in this application embodiment is as follows: When it is necessary to change the mold 7 for hot stamping processing, the servo motor 27 at the bottom of the frame body 3 is first started by the controller. The output shaft of the servo motor 27 drives the drive rod 6 to rotate. Because the drive rod 6 is hinged to the drive sliding block 10 in the drive groove 11 on the outer side wall of the worktable 9, the rotation of the drive rod 6 will drive the drive sliding block 10 to slide along the drive groove 11, thereby driving the worktable 9 to move outward along the inner groove 4. When the worktable 9 moves to the designated position on the outside, the mounting block 26 at the bottom of the new mold 7 is aligned with the mounting hole on the fixed seat 8, and the mounting block 26 is made to contact the moving seat 13.

[0032] After the mounting block 26 of the new mold 7 comes into contact with the movable seat 13, the movable seat 13 is pushed to move downward. The movable seat 13 drives the sliding sleeve 16 to slide downward along the sliding column 17. The sliding sleeve 16 drives the surrounding fixed blocks 19 to move inward through the connecting rod 15 until the fixed blocks 19 engage with the mounting block 26 of the mold 7, thus achieving the initial fixation of the mold 7. During the downward movement of the sliding sleeve 16, the pulleys 18 on both sides of the sliding sleeve 16 slide along the groove on the inclined plate 20, causing the inclined plate 20 to retract into the fixed seat 8. The inclined plate 20 drives the connecting round rod 21 to retract. The limiting slider 5, which is fixedly connected to one end of the connecting round rod 21, slides along the outer groove 23 to the side of the limiting rod 25. At this time, the limiting rod 25 is rotated to engage with the T-slot 24, limiting the limiting slider 5 and preventing it from retracting, thereby completing the fixation of the inclined plate 20 and ensuring that the new mold 7 is installed stably.

[0033] If it is necessary to disassemble the old mold 7, rotate the limiting rod 25 to separate it from the T-slot 24. Since the spring 22 is in a compressed state when the new mold 7 is installed, the spring 22 releases its elasticity, causing the connecting rod 21 to rebound. The limiting slider 5 loses the restriction of the limiting rod 25, and the inclined plate 20 rebounds under the action of the spring 22. The inclined plate 20 drives the pulley 18 to move slowly upward. The pulley 18 drives the sliding sleeve 16 to move upward. The sliding sleeve 16 drives multiple fixing blocks 19 to move outward through the connecting rod 15, so that the fixing blocks 19 are separated from the mounting block 26 of the mold 7, thus completing the disassembly of the old mold 7.

[0034] After the new mold 7 is installed, the servo motor 27 is started again by the controller, driving the worktable 9 to move along the inner groove 4 towards the bottom of the hot stamping machine body 2. When the worktable 9 moves to the designated position for hot stamping, the hot stamping machine body 2 is started to perform hot stamping on the material on the mold 7. After hot stamping is completed, the servo motor 27 drives the worktable 9 to move out of the hot stamping area for subsequent processes such as part removal and quality inspection. It also prepares for the next mold change and processing operation. The whole process is repeated, realizing fast mold change and efficient hot stamping.
