[0002] In today's commodity economy, the packaging industry plays a crucial role as a vital link in product circulation. From everyday consumer goods to electronics, from food to industrial components, almost all products rely on packaging for protection and decoration. Paper boxes, as a widely used packaging material, occupy a significant share of the packaging market due to their advantages such as low cost, ease of processing, and environmental recyclability. Whether it's a small, exquisite gift box or a large logistics transport carton, paper boxes, with their diverse forms and functions, meet the packaging needs of different industries and products.

[0003] The structure of some cardboard box corner-folding rapid prototyping molds mainly consists of a positioning mechanism, a corner-folding mechanism, and a driving mechanism. During operation, the positioning mechanism first precisely fixes the cardboard in the reference position of the mold cavity to prevent displacement during the forming process. Then, the driving mechanism drives the corner-folding mechanism to move. The corner-folding pressure block cooperates with the forming die to squeeze and bend the corners of the cardboard according to the preset angle. At the same time, the heating component assists the cardboard to quickly shape and ensures accurate corner dimensions.

[0004] In existing technologies, after the cardboard box is folded and formed in the mold, it needs to be smoothly removed from the mold for subsequent processing and packaging. However, some existing mold structures are difficult to demold the cardboard box quickly, resulting in low productivity. Therefore, a cardboard box corner folding rapid forming mold structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rapid prototyping mold structure for cardboard box corners, aiming to improve the problem that some existing mold structures are difficult to quickly demold cardboard boxes.

[0011] 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. Example

[0012] The structure of the rapid prototyping mold for cardboard box corners is as follows: Figure 1 , Figure 3 and Figure 4 The base plate 1 is the basic load-bearing component of the mold. An L-shaped plate 2 is fixedly connected to the top of the base plate 1. The L-shaped plate 2 provides sliding guidance and structural support for the guide mechanism 4. A demolding mechanism 3 is fixedly connected to the top of the base plate 1. The guide mechanism 4 is slidably connected inside the L-shaped plate 2. The demolding mechanism 3 includes a forming box 31, the inner wall shape of which matches the outer contour of the cardboard box to be formed. The bottom of the forming box 31 is fixedly connected to the top of the base plate 1. A top plate 32 is slidably connected to the inner side of the forming box 31. After the cardboard box is formed, the top plate 32 moves upward to push the formed cardboard box out of the forming box 31, thus achieving the demolding action. A connecting plate 33 is fixedly connected to the outside of the top plate 32. The connecting plate 33 is used to cooperate with the limiting block 38 to limit the position of the top plate 32. A spring component 34 is fixedly connected to the bottom of the top plate 32. An externally fixed connection is provided by a connecting box 35, which serves as structural protection and component positioning. An internally fixed connection is provided by a round rod 36, which provides a sliding guide for the limiting block 38. The limiting block 38 is slidably connected externally to the round rod 36. The limiting block 38 locks the top plate 32 in position by inserting into a slot in the connecting plate 33. When an external force pushes the push rod 39, the limiting block 38 slides along the round rod 36 and exits the slot, releasing the lock. A limiting spring 37 is sleeved on the outside of the round rod 36, and the elastic force of the limiting spring 37 keeps the limiting block 38 in position. 8. While the connecting plate 33 is inserted, when the push rod 39 is pushed, the limiting block 38 compresses the limiting spring 37 and disengages from the connecting plate 33, releasing the lock on the top plate 32 and limiting the position of the top plate 32. The limiting block 38 is externally fixedly connected to the push rod 39. The operator can push the push rod 39 to move the limiting block 38, thereby manually unlocking the top plate 32. The connecting plate 33 is externally slidably connected to the inside of the connecting box 35, and the limiting block 38 is externally slidably connected to the inside of the connecting plate 33. The limiting spring 37 is externally... One end of the limiting spring 37 is fixedly connected to the outside of the limiting block 38, and the other end of the limiting spring 37 is fixedly connected to the inside of the connecting box 35. The outside of the limiting block 38 is slidably connected to the inside of the connecting box 35, and the outside of the push rod 39 is slidably connected to the inside of the connecting box 35. The elastic component 34 includes a demolding spring 341. After the corner is formed, the demolding spring 341 releases its elastic force, pushing the top plate 32 to move upward to complete the demolding. The top of the demolding spring 341 is fixedly connected to the bottom of the top plate 32, and the bottom of the demolding spring 341 is fixedly connected to the inside of the molding box 31. Specifically, the limiting block 38 is inserted into the slot of the connecting plate 33, and the position of the top plate 32 is locked under the action of the limiting spring 37. The demolding spring 341 is in a compressed state. After the corner forming is completed, the operator pushes the push rod 39, which drives the limiting block 38 to slide along the round rod 36 and compress the limiting spring 37, so that the limiting block 38 is separated from the connecting plate 33, releasing the lock on the top plate 32. The demolding spring 341 releases its elastic force, pushing the top plate 32 to move upward in the forming box 31, and pushing the formed cardboard box out of the forming box 31 to complete the demolding.

[0013] Reference Figure 1 and Figure 2The guiding mechanism 4 includes a guide rod 41, which provides vertical sliding guidance for the pressing plate 431, ensuring that the pressing plate 431 remains horizontal during up-and-down movement and that the force on the folded corner of the cardboard box is even. The guide rod 41 is externally slidably connected to the inside of the L-shaped plate 2. A limiting circular plate 42 is fixedly connected to the top of the guide rod 41. The diameter of the limiting circular plate 42 is larger than the diameter of the mating hole between the guide rod 41 and the L-shaped plate 2, which serves to limit the stroke and prevent the guide rod 41 from slipping out of the L-shaped plate 2. A pressing assembly 43 is fixedly connected to the bottom of the guide rod 41. The pressing assembly 43 includes a pressing plate 43. 31. Pressing plate 431 moves downward under the drive of cylinder 5 to perform corner forming operation on the paper box inside forming box 31. The top of pressing plate 431 is fixedly connected to the bottom of guide rod 41. Cylinder 5 is fixedly connected inside L-shaped plate 2. Cylinder 5 drives pressing plate 431 to quickly and stably complete the corner forming action on paper box through telescopic movement. The driving end of cylinder 5 is fixedly connected to the top of pressing plate 431. Limiting plate 6 is fixedly connected to the outside of forming box 31. Limiting plate 6 is used to limit the movement range of connecting plate 33. Tool box is fixedly connected to the outside of forming box 31. Specifically, cylinder 5 starts and drives pressing plate 431 to move downward. Pressing plate 431 drives guide rod 41 to slide along the inside of L-shaped plate 2. Limiting round plate 42 moves down synchronously with guide rod 41 until the corner forming operation is completed. During the corner forming process, guide rod 41 maintains vertical sliding guidance to ensure that pressing plate 431 moves horizontally. Limiting round plate 42 can prevent guide rod 41 from slipping. After forming is completed, cylinder 5 drives pressing plate 431 to reset upward, and guide rod 41 moves up accordingly.

[0014] The implementation principle of this application embodiment is as follows: The operator places the cardboard box to be folded into the forming box 31. At this time, the limiting block 38 is inserted into the slot of the connecting plate 33, and the position of the top plate 32 is locked under the action of the limiting spring 37, and the demolding spring 341 is in a compressed state. Subsequently, the cylinder 5 is started and drives the pressing plate 431 to move downward. The pressing plate 431 drives the guide rod 41 to slide along the inside of the L-shaped plate 2. The limiting round plate 42 moves down synchronously with the guide rod 41. The limiting round plate 42 can prevent the guide rod 41 from falling too far until the pressing plate 431 contacts and acts on the cardboard box, completing the corner folding and forming operation. After the corner forming is completed, the cylinder 5 drives the pressing plate 431 to reset upward, and the guide rod 41 moves upward accordingly. Then, the operator pushes the push rod 39, which drives the limiting block 38 to slide along the round rod 36 and compress the limiting spring 37, so that the limiting block 38 is separated from the connecting plate 33. After the locking of the top plate 32 is released, the demolding spring 341 releases its elastic force, pushing the top plate 32 to move upward in the forming box 31, and ejecting the formed paper box from the forming box 31 to complete the demolding. The limiting plate 6 can limit the movement range of the connecting plate 33.
