Description

Technical Field

[0001] This utility model relates to the technical field of foam product processing equipment, specifically to a rapid demolding device for an integrated molding die for foam packaging boxes. Background Technology

[0002] In the production process of foam packaging boxes, the integrated molding die is a key piece of equipment to ensure the accuracy of the product's shape and dimensions. After the mold completes the foaming process, it needs to be quickly removed from the molding equipment, a process known as "demolding." The efficiency of this step directly affects the overall production rhythm.

[0003] Existing demolding methods mostly rely on manual handling or simple tools, which have many problems: When demolding manually, the mold is heavy, the operator's labor intensity is high, and the mold is easily damaged due to uneven force, which affects the quality of subsequent products; the clamping structure of simple tools is fixed and cannot be adapted to foam packaging box molds of different sizes, resulting in poor versatility. Special tools are required for different mold specifications, which increases production costs; some demolding devices use unidirectional drive, which results in uneven force when clamping the mold, which can easily cause the mold to tilt or even fall off, posing a safety hazard.

[0004] In addition, the existing device lacks a protective structure for the mold, which can easily cause scratches on the mold surface during clamping and shorten the mold's service life; the device as a whole is inconvenient to move and cannot be flexibly transferred to different molding equipment in the production workshop, which reduces the ease of operation.

[0005] In view of this, we propose a rapid demolding device for an integrated molding die for foam packaging boxes. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a quick demolding device for an integrated molding die for foam packaging boxes.

[0007] The technical solution of this utility model is:

[0008] A rapid demolding device for an integrated molding die for foam packaging boxes includes a vertical plate with a movable opening at its center. Two movable frames are symmetrically slidably installed within the movable opening. A drive mechanism for driving the two movable frames is installed within the movable opening. Each movable frame includes a drive plate slidably installed within the movable opening. A main body is integrally formed on the drive plate, and a movable plate is slidably installed within the main body. A clamping plate is fixed to one end of the movable plate away from the main body. A protective pad is fixedly connected to the outer wall of the clamping plate. An L-shaped rod is fixedly connected to the outer walls of both sides of the vertical plate, and a handle is fixedly installed on the L-shaped rod. By setting two symmetrical sliding frames within the movable opening of the vertical plate, and cooperating with the drive mechanism, the frames can move relative to or towards each other. The clamping plates at the ends of the movable plates can stably hold the foam packaging box forming mold, and can adapt to the use of foam boxes of different sizes, increasing its versatility and practicality during use. The protective pads on the outer wall of the clamping plates can prevent damage to the mold during clamping, thus providing protection. The L-shaped rods and handles on both sides of the vertical plate make it easy for operators to hold and move the device. The overall structure realizes convenient clamping and moving of the mold, providing a basis for rapid demolding and improving operational convenience.

[0009] As a preferred technical solution, the driving mechanism includes a double-threaded screw rotatably mounted within the movable opening. The double-threaded screw comprises two parts with opposite threads, and two driving plates are respectively threadedly connected to the two parts of the double-threaded screw with opposite thread directions. When the double-threaded screw rotates, it can drive the two driving plates to synchronously slide relative to or towards each other, realizing symmetrical driving of the two movable frames and ensuring balanced force when clamping the mold.

[0010] As a preferred technical solution, the drive mechanism further includes a transmission box rotatably mounted on the double-threaded lead screw. The transmission box houses a first bevel gear and a second bevel gear that mesh with each other, with the second bevel gear coaxially fixed to the double-threaded lead screw. In use, rotating the first bevel gear can drive the second bevel gear, which in turn drives the double-threaded lead screw, thus adjusting the distance between the two movable frames.

[0011] As a preferred technical solution, the drive mechanism further includes an adjusting motor fixed to the top of the vertical plate. The output shaft of the adjusting motor is coaxially fixed to a transmission shaft, the bottom of which passes through and is rotatably connected to a transmission box. The transmission shaft is coaxially fixed to the first bevel gear. The adjusting motor is connected to the first bevel gear via the transmission shaft. When the motor is working, it can drive the transmission shaft and the first bevel gear to rotate, which in turn drives the double-threaded screw to rotate through the meshing second bevel gear, thus realizing the electric drive of the movable frame.

[0012] As a preferred technical solution, a hydraulic cylinder is fixedly connected inside the movable plate of each movable frame, and the piston rod of the hydraulic cylinder is fixedly connected to one end of the main body. The extension and retraction of the hydraulic cylinder piston rod can drive the movable plate to slide relative to the main body, realizing the extension and retraction function of the clamping plate. The extension length of the clamping plate can be adjusted according to the size of the mold, expanding the adaptability of the device to molds of different specifications and enhancing the versatility and practicality of the device.

[0013] As a preferred technical solution, two support columns are symmetrically fixedly installed at the bottom of the vertical plate, and a base is provided below the vertical plate. The bottoms of both support columns are fixedly connected to the top of the base. The two support columns, fixed to the base, create a stable support structure between the vertical plate and the base.

[0014] As a preferred technical solution, a caster wheel is fixedly connected to each of the four corners of the base. This allows the device to move flexibly and easily be transferred to different working positions.

[0015] As a preferred technical solution, when the hydraulic cylinder piston rod is retracted to its shortest length, the movable plate retracts into the main body. This reduces the space occupied by the device when it is not in operation, facilitating its storage and refurbishment.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

Two movable frames 3 are symmetrically slidably installed in the movable opening 10. A drive mechanism for driving the two movable frames 3 is installed in the movable opening 10. The movable frame 3 includes a drive plate 31 slidably installed in the movable opening 10. A main body 30 is integrally formed on the drive plate 31. A movable plate 32 is slidably installed in the main body 30. A clamping plate 33 is fixed at the end of the movable plate 32 away from the main body 30. A protective pad 34 is fixedly connected to the outer wall of the clamping plate 33. An L-shaped rod 2 is fixedly connected to the outer walls on both sides of the vertical plate 1. A handle 20 is fixedly installed on the L-shaped rod 2. By setting two symmetrically sliding movable frames 3 within the movable opening 10 of the vertical plate 1, and cooperating with the drive mechanism, the movable frames 3 can move relative to each other or towards each other. The clamping plate 33 at the end of the movable plate 32 can stably clamp the foam packaging box forming mold and can adapt to the use of foam boxes of different sizes, increasing the versatility and practicality during use. The protective pad 34 on the outer wall of the clamping plate 33 can prevent damage to the mold during clamping and play a protective role. The L-shaped rods 2 and handles 20 on both sides of the vertical plate 1 make it easy for operators to hold and carry the handling device. The overall structure realizes convenient clamping and carrying of the mold, provides a basis for rapid demolding, and improves the convenience of operation.

[0027] In a preferred embodiment, the driving mechanism includes a double-threaded screw 13 rotatably mounted within the movable opening 10. The double-threaded screw 13 comprises two parts with opposite threads, and two driving plates 31 are respectively threadedly connected to the two parts of the double-threaded screw 13 with opposite thread directions. When the double-threaded screw 13 rotates, it can drive the two driving plates 31 to synchronously slide relative to or towards each other on the movable frame 3, realizing symmetrical driving of the two movable frames 3 and ensuring balanced force when clamping the mold.

[0028] In a preferred embodiment, the drive mechanism further includes a transmission box 12 rotatably mounted on the double-threaded lead screw 13. The transmission box 12 houses a first bevel gear 120 and a second bevel gear 121 that mesh with each other, and the second bevel gear 121 is coaxially fixed to the double-threaded lead screw 13. In use, the first bevel gear 120 can be rotated, which in turn drives the second bevel gear, thereby rotating the double-threaded lead screw 13, thus allowing adjustment of the distance between the two movable frames 3.

[0029] In a preferred embodiment, the drive mechanism further includes an adjustment motor 11 fixed to the top of the vertical plate 1. A transmission shaft 14 is coaxially fixed to the output shaft of the adjustment motor 11. The bottom of the transmission shaft 14 passes through and is rotatably connected to the transmission box 12. The transmission shaft 14 is coaxially fixed to the first bevel gear 120. The adjustment motor 11 is connected to the first bevel gear 120 via the transmission shaft 14. When the motor is working, it can drive the transmission shaft 14 and the first bevel gear 120 to rotate, which in turn drives the double-threaded screw 13 to rotate via the meshing second bevel gear 121, thus realizing the electric drive of the movable frame 3.

[0030] In a preferred embodiment, each movable frame 3 has a hydraulic cylinder 35 fixedly connected inside its movable plate 32, and the piston rod of the hydraulic cylinder 35 is fixedly connected to one end of the main body 30. The extension and retraction of the piston rod of the hydraulic cylinder 35 drives the movable plate 32 to slide relative to the main body 30, thus realizing the extension and retraction function of the clamping plate 33. This allows the extension length of the clamping plate 33 to be adjusted according to the size of the mold, expanding the adaptability of the device to molds of different specifications and enhancing the versatility and practicality of the device.

[0031] In a preferred embodiment, two support columns 4 are symmetrically fixedly installed at the bottom of the vertical plate 1, and a base 5 is provided below the vertical plate 1. The bottoms of the two support columns 4 are fixedly connected to the top of the base 5. The two support columns 4, fixed to the base 5, form a stable support structure between the vertical plate 1 and the base 5.

[0032] As a preferred embodiment, each of the four corners of the base 5 is fixedly connected to a caster wheel 6. This allows the device to move flexibly and is convenient for transferring the device to different working positions.

[0033] As a preferred embodiment, when the piston rod of the hydraulic cylinder 35 is retracted to its shortest length, the movable plate 32 retracts into the main body 30. This reduces the space occupied by the device when it is not in operation, making it easier to store and fold up the device.

[0034] Before use, the quick demolding device of the integrated foam packaging box molding mold of this utility model can be flexibly moved to the working position of the integrated foam packaging box molding mold by means of the universal wheels 6 at the bottom of the base 5. The operator can use the handles 20 on the L-shaped rods 2 on both sides of the vertical plate 1 to assist in moving or adjusting the placement posture of the device to ensure that the device is placed stably.

[0035] Based on the dimensions of the mold to be demolded, the extension length of the movable plate 32 is first adjusted using the hydraulic cylinder 35. When the piston rod of the hydraulic cylinder 35 extends or retracts, it drives the movable plate 32 to slide relative to the main body 30, causing the clamping plate 33 to extend to a position suitable for the mold width. When the piston rod of the hydraulic cylinder 35 is retracted to its shortest length, the movable plate 32 can be stored inside the main body 30, reducing space occupation. Subsequently, the adjustment motor 11 at the top of the vertical plate 1 is started. The output shaft of the adjustment motor 11 drives the transmission shaft 14 to rotate. The transmission shaft 14 transmits power through the meshing first bevel gear 120 and second bevel gear 121 in the transmission box 12, causing the double threaded screw 13, which is coaxially fixed with the second bevel gear 121, to rotate. Since the two threads of the double threaded screw 13 are opposite and are respectively threadedly connected to the drive plates 31 of the two movable frames 3, when the double threaded screw 13 rotates, it drives the two movable frames 3 to slide along the movable opening 10 of the vertical plate 1, thereby driving the clamping plate 33 to approach the inner wall of the foam box, thus clamping the foam box.

[0036] When the clamping plate 33 contacts the mold, the protective pad 34 on the outer wall of the clamping plate 33 can prevent damage to the mold. The mold is stably clamped by the symmetrical drive of the two movable frames 3. After clamping, the operator can remove the mold from the molding equipment by using the handle 20 or the universal wheels 6 to complete the quick demolding operation.

[0037] After demolding, the regulating motor 11 is started in reverse, causing the double threaded screw 13 to rotate in the opposite direction, driving the two movable frames 3 to separate towards each other and release the mold; at the same time, the hydraulic cylinder 35 can be controlled to retract the movable plate 32, making it easy to store the device or perform the next demolding operation. The support column 4 at the bottom of the vertical plate 1 and the base 5 form a stable support, ensuring that the device is not easy to shake during the entire operation, improving the safety and efficiency of operation.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
