Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a rapid assembly device for a large packaging box combination mold. Background Technology

[0002] In modern industrial logistics, packaging boxes, as key containers for carrying and protecting goods, are widely used in the transportation and storage of various products. Among them, metal packaging boxes, with their high strength and corrosion resistance, occupy an important position in scenarios such as industrial equipment and hazardous materials transportation. The manufacturing of metal packaging boxes largely relies on stamping dies and die-casting dies, especially combined stamping dies. By combining multiple functional components, multiple processes such as punching, bending, and forming are carried out in a coordinated manner to meet the production needs of boxes of different specifications.

[0003] However, existing modular stamping dies still have room for optimization in the stamping process of metal packaging boxes. Key internal components such as dies and punches are prone to wear and deformation due to long-term exposure to high-intensity impact loads. When these components need to be replaced or adjusted, traditional dies often use bolted connections and overall disassembly, resulting in cumbersome and time-consuming operations, reducing production efficiency and increasing maintenance costs. Therefore, we propose a rapid assembly device for modular dies used in large packaging boxes. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rapid assembly device for large packaging box combination molds to solve the technical problems of inconvenient replacement of components in combination stamping molds and low mold switching efficiency when producing multiple specifications.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a rapid assembly device for a large packaging box combination mold, including a base plate, a base arranged in the middle of the upper surface of the base plate, a mold mechanism arranged on the upper surface of the base plate, a frame arranged at both ends of the upper surface of the base plate, a power mechanism arranged at the upper end of the frame, and an assembly mechanism arranged at the lower end of the power mechanism.

[0006] The splicing mechanism includes a top plate, a slot A inside the top plate, a plug A inserted in the middle of the slot A, a slot B inside the plug A, a plug B inserted in the slot B, a rack arranged on the upper surface of one end of the plug B, a gear meshing on the surface of the rack, and the gear being rotatably mounted in the slot B, a retaining plate arranged on the gear, one end of the retaining plate being arranged in a retaining slot, and the retaining slot being opened on the upper surface inside the slot A.

[0007] Preferably, the mold mechanism includes a punch arranged on the upper surface of the base, a die arranged directly above the punch, and the upper surface of the die is connected to the insert block A by bolts.

[0008] Preferably, the power mechanism includes a hydraulic cylinder, the output end of which is connected to a plate, the lower surface of which is connected to a top plate by bolts, and sliding sleeves are installed through the four corners of the plate. Sliding rods are inserted into the sliding sleeves and are arranged within the frame.

[0009] Preferably, both the slot A and the insert A are in the shape of a dovetail structure, and the insert A is inserted into the slot A in a fitting manner.

[0010] Preferably, an elastic piston is arranged at one end of the slot A, and a push block is arranged at the end of the elastic piston, and the width of the push block matches the width of the slot B.

[0011] Preferably, a handle B is provided at one end of the insertion block B, and a handle A is provided below the handle B, and the handle A is fixed on the insertion block A.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs a slot A and a plug A structure, both of which adopt a dovetail structure design. After the plug A is inserted into the slot A, the die and the plate can be connected. Compared with the common T-shaped structure insertion method, the dovetail structure, with its trapezoidal cross-section and bidirectional self-locking characteristics, can enhance the stability of the plug A after insertion without additional bolt tightening. It is especially suitable for dynamic load environments during stamping. At the same time, the insertion connection does not require tightening each bolt individually, which makes it easier to quickly assemble and disassemble the die and the plate, effectively improving the switching efficiency of mold components in multi-specification production.

[0014] 2. This utility model, through the design of a card plate and a bayonet structure, allows the card plate to rotate obliquely and engage with the bayonet after insert block A and insert block B are inserted into slot A. This structure utilizes the meshing transmission of gears and racks to prevent insert block A from coming out when no manual force is applied continuously. Compared with traditional bolt connections, it can reduce the risk of loosening caused by vibration and effectively ensure the stability of the die and plate after connection.

[0015] 3. This utility model, through the design of a gear and rack structure, allows the insert block A to be inserted into slot A, and the pull-out insert block B to drive the rack to move within slot B. The meshing gear rotates and controls the locking plate to engage with the slot. This structure allows the internal locking state to be controlled from outside the top plate. Compared with the traditional built-in locking mechanism, it improves the ease of operation and makes it easier for workers to control the connection and disconnection of the die.

[0025] like Figures 1 to 7 As shown, the present invention relates to a large packaging box combination mold quick splicing device, including a base plate 1, a base 2 arranged in the middle of the upper surface of the base plate 1, a mold mechanism 3 arranged on the upper surface of the base 2, a frame 4 arranged at both ends of the upper surface of the base plate 1, a power mechanism 5 arranged at the upper end of the frame 4, and a splicing mechanism 6 arranged at the lower end of the power mechanism 5.

[0026] The splicing mechanism 6 includes a top plate 601, a slot A602 is provided inside the top plate 601, a plug A603 is inserted in the middle of the slot A602, a slot B604 is provided inside the plug A603, a plug B605 is inserted into the slot B604, a rack 606 is arranged on the upper surface of one end of the plug B605, a gear 607 is meshed on the surface of the rack 606, and the gear 607 is rotatably installed in the slot B604, a retaining plate 608 is arranged on the gear 607, one end of the retaining plate 608 is arranged in the retaining slot 609, and the retaining slot 609 is opened on the upper surface inside the slot A602. This invention, through the design of a locking plate 608 and a locking slot 609, allows the locking plate 608 to rotate obliquely and engage with the locking slot 609 after the insert block A603 carrying the insert block B605 is inserted into the slot A602. This structure utilizes the meshing transmission of a gear 607 and a rack 606 to prevent the insert block A603 from dislodging when no continuous manual force is applied. Compared to traditional bolt connections, this reduces the risk of loosening due to vibration and effectively ensures the stability of the connection between the die 302 and the plate 502. Furthermore, by designing the gear 607 and rack 606 structure, after the insert block A603 is inserted into the slot A602, pulling the insert block B605 causes the rack 606 to move within the slot B604, while the meshing gear 607 rotates and controls the movement. The locking plate 608 engages with the locking slot 609. This structure allows for external control of the internal locking state from the top plate 601. Compared to traditional built-in locking mechanisms, this improves operational convenience and facilitates operator control of the connection and disconnection of the die 302. Through the design of the insert block B605 and slot B604, the rack 606 and gear 607 controlling the position of the insert block A603 in the slot A602 can achieve rotational control. When the insert block A603 is inserted into the slot A602, the operator does not need to move the insert block A603. Instead, they only need to manipulate the rack 606 in the slot A602 to engage the gear 607, thereby driving the locking plate 608 to rotate and engage with the locking slot 609, thus achieving individual control of the connection state.

[0027] In an embodiment of this invention, the mold mechanism 3 includes a punch 301 arranged on the upper surface of the base 2, a die 302 arranged directly above the punch 301, and the upper surface of the die 302 connected to the insert block A603 by bolts. This invention, through the design of the die 302 and punch 301, allows the metal sheet to be stamped into a packaging box to be placed between them, and then the hydraulic cylinder 501 outputs power to stamp the metal sheet into a packaging box, achieving the effect of stamping into a box.

[0028] In an embodiment of this utility model, the power mechanism 5 includes a hydraulic cylinder 501. The output end of the hydraulic cylinder 501 is connected to a plate 502. The lower surface of the plate 502 is connected to a top plate 601 by bolts. Sliding sleeves 503 are installed through the four corners of the plate 502. Sliding rods 504 are inserted into the sliding sleeves 503 and are arranged within the frame 4. The hydraulic cylinder 501 of this utility model allows the plate 502 to move up and down within the frame 4, indirectly controlling the position of the die 302 and providing a power output point. The installation of the sliding sleeves 503 and the sliding rods 504 stabilizes the four sides of the plate 502 when it is pushed, pulled, raised, and lowered by the hydraulic cylinder 501, allowing it to stably carry the die 302 connected to its lower surface within the frame 4 for up and down movement.

[0029] In the embodiments of this utility model, both the slot A602 and the insert A603 are dovetail-shaped, and the insert A603 fits snugly into the slot A602. This utility model, through the design of the slot A602 and insert A603 structures, both adopts a dovetail design. After the insert A603 is inserted into the slot A602, the die 302 and the flat plate 502 can be connected. Compared with the common T-shaped insertion method, the dovetail structure, with its trapezoidal cross-section and bidirectional self-locking characteristics, enhances the stability of the insert A603 after insertion without additional bolt tightening, making it particularly suitable for dynamic load environments during stamping. Furthermore, the insertion connection eliminates the need to tighten bolts individually, facilitating the rapid assembly and disassembly of the die 302 and the flat plate 502, effectively improving the switching efficiency of mold components in multi-specification production.

[0030] In an embodiment of this invention, an elastic piston 6010 is arranged at one end of the slot A602, and a push block 6011 is arranged at the end of the elastic piston 6010. The width of the push block 6011 matches the width of the slot B604. By designing the elastic piston 6010 and push block 6011, when the insert block A603 carrying the insert block B605 is inserted into the slot A602, the push block 6011, under the action of the elastic piston 6010, inserts into the slot B604, pushing the insert block B605 to move. During this process, the rack 606 drives the gear 607 to rotate, causing the locking plate 608 to automatically tilt and engage with the slot 609, thus locking the insert block A603. This linkage design requires no additional power source; the insertion block positioning and locking of the locking plate 608 can be completed synchronously through the insertion action alone. Compared with the traditional manual operation structure, it can reduce the component switching steps by more than 50%, effectively improving the mold assembly efficiency.

[0031] In an embodiment of this utility model, a handle B6012 is provided at one end of the insertion block B605, and a handle A6013 is provided below the handle B6012, with the handle A6013 fixed to the insertion block A603. This utility model, through the design of the handles B6012 and A6013, allows workers to simultaneously and independently apply pushing and pulling forces to both insertion blocks B605 and A603, providing a location for the power output point.

[0032] Working Principle: This embodiment provides a rapid assembly device for large packaging box modular molds. Before use, the operator needs to connect an external power supply and control its operation via a control panel. Before use, the operator also needs to install the mold 302 to be used under the flat plate 502. Specifically, the operator lifts the mold 302 and inserts the insert block A603 mounted on the upper surface of the mold 302 into the slot A602. When the insert block A603 is inserted into the slot A602, the push block 6011 installed in the slot A602 will be elastically pushed by the elastic piston 6010, causing the insert block B605 to move within the slot B604. After the movement, the rack 606 on its surface will mesh with the gear 607. After the gear 607 meshes, it will rotate the clamping plate 608 and tilt it upwards. In this way, the clamping plate 608 will be inserted into the clamping slot 609, thereby restricting the insert block A603 in the slot A602, completing the quick splicing and installation operation of the die 302 and the plate 502. After the die 302 is installed, the worker will place the metal plate to be stamped into a packaging box on the punch 301 in the center. After placement, the worker will control the hydraulic cylinder 501 to push the plate 502 connected to the output end. After the plate 502 descends, it will bring the die 302 connected to the lower surface down with it. After the die 302 descends, The die 302 will adhere to the surface of the punch 301 and press the punch 301 into it, thus stamping the metal sheet placed on the surface of the punch 301 into a packaging box. After stamping, the hydraulic cylinder 501 lifts the die 302, and the operator removes the stamped metal packaging box from the punch 301, completing the stamping operation. When the die 302 is damaged due to prolonged stamping and needs to be replaced, the operator holds handle A6013 and places their palm against handle B6012, applying force to push the insert A603 into the slot A602, moving the insert B605 along with it. This rotates the insert A605. The card plate 608 will rotate out of the slot 609. After the card plate 608 is out of the slot 609, the operator does not need to push the insert A603 anymore, but needs to continue pushing the insert B605. In this way, the rack 606 will continue to mesh with the gear 607 and make the card plate 608 rotate parallel to the slot B604. Finally, the operator pushes the handle B6012 to keep the insert B605 in the position of the slot B604 and applies a pulling force to the handle A6013 to pull the insert A603 out of the slot A602 as a whole, completing the separation of the die 302 and the plate 502. The operator takes the new die 302 and repeats the previous splicing operation.
