Description

Technical Field

[0001] This utility model relates to the field of pulp molding equipment technology, and in particular to a quick disassembly and transfer device for pulp molding molds. Background Technology

[0002] In the pulp molding production process, the mold, as the core molding component, undergoes frequent disassembly, assembly, and maintenance. The rapid replacement and proper maintenance of the mold directly affect the production efficiency and molding quality of the product. However, under current technology, the disassembly and transfer of pulp molding molds still rely on traditional methods, lacking specialized auxiliary devices. Currently, the industry commonly uses manual handling or simple tools to transfer molds. This traditional operating mode has many drawbacks: First, it is inefficient. Due to the large weight of pulp molding molds, a single handling often requires multiple people working together, which not only consumes a lot of labor costs but also takes a long time, seriously affecting the production rhythm. Second, it poses significant safety hazards. After production is completed, the mold remains at a high temperature, and direct contact with operators can easily cause burns. At the same time, if the mold slips during handling due to improper operation, it may cause equipment damage or even serious personal injury accidents. These problems make the disassembly and transfer of molds a key bottleneck restricting the efficient and safe operation of pulp molding production. Therefore, there is an urgent need to develop a specialized pulp molding die disassembly and transfer device to solve the problems of low efficiency and high safety risks of manual handling in the existing technology, improve the level of automation and safety of production, and ensure the stable and efficient operation of pulp molding production. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a quick disassembly and transfer device for pulp molding molds, which solves the problems mentioned in the background art, such as the large weight of the existing molds, the need for multiple people to work together to move them, the time and effort required, the low efficiency, the fact that the molds are still in a high temperature state after production on the machine, and the risk of burns from direct contact with people; and the possibility of personal injury or equipment damage if the mold slips during the handling process.

[0004] The technical solution adopted by this utility model is as follows: it includes a mold, and the top surface of the mold is provided with connecting holes at the four corners. The inner wall of the connecting holes is provided with internal threads, and a connector is screwed into the inside of the connecting holes.

[0005] A plug is fixedly connected to the bottom end face of the connector. The plug has a cylindrical structure and a positioning hole that runs through both the front and rear sides on the outer circumference of the plug. A limit plate is fixedly connected to the top end face of the connector, and a calibration groove is provided inside the limit plate.

[0006] Preferably, a connecting rod is fixedly connected to the top surface of the limiting plate. The connecting rod is a solid cylindrical structure, and a top plate is fixedly connected to the top surface of the connecting rod.

[0007] Preferably, the top plate has a circular cross-section, and a limiting head is fixedly connected to the top surface of the top plate, with external threads on the outer circumferential surface of the limiting head.

[0008] Preferably, a transfer plate is sleeved on the outer side of the limiting head. The transfer plate is used to connect with the forklift shovel plate, and the interior of the transfer plate has two screw holes that match the limiting head in a linear array.

[0009] Preferably, a positioning nut is screwed onto the outer side of the limiting head. The positioning nut is located directly above the transfer plate and is used to limit the position of the transfer plate.

[0010] Preferably, the outer side of the mold has a limit hole, and there are four limit holes in total, wherein every two longitudinally adjacent limit holes form a group.

[0011] Preferably, the two sets of limiting holes are respectively opened on the left and right sides of the mold, and the two sets of limiting holes are respectively connected to the four connecting holes.

[0012] Preferably, a limiting pin is inserted into the limiting socket, the limiting pin matches the positioning hole, and a calibration block matching the calibration slot is fixedly connected to the top surface of the mold. The calibration block is used to calibrate the position of the calibration slot and does not contact the calibration slot.

[0013] The beneficial effects of this utility model are: 1. In this utility model, a standardized mechanical interface system is constructed by connecting the connecting holes at the four corners of the mold top surface and the threaded connection of the connector. The plug at the bottom of the connector extends into the connecting hole, and the tight engagement of the internal and external threads provides stable axial tension. Compared with the unstable contact that relies on friction when manually handling the mold, this rigid connection can withstand a larger load and ensure that the mold will not tilt or fall off due to uneven force during the transfer process. The limiting plate at the top and the connecting rod form a vertical force transmission structure. The operator applies force by holding the top plate, changing the traditional "lifting" and "dragging" to "pulling" and "traction", which conforms to ergonomic design and reduces strain on the waist and arms.

[0014] 2. In this utility model, the external thread of the limiting head and the screw hole of the transfer plate form a detachable mechanical connection node. By tightening the positioning nut, the transfer plate is fixed to the top of the limiting head. The spacing of the internal screw holes precisely matches the standard size of the forklift shovel, achieving seamless docking with industrial handling equipment. This design simplifies the traditional lifting operation that requires one person to operate a forklift. With the locking of the plug by the limiting pin, it can ensure that the mold remains horizontal during the lifting process and avoid the risk of slippage due to the shift of the center of gravity. According to actual measurements, after adopting this device, the single lifting time is shortened from the traditional minutes to minutes, significantly improving the continuity of the production line. The positioning hole on the outer periphery of the plug and the limiting insertion hole on the outer side of the mold are connected by the limiting pin to form a circumferential locking structure, preventing the connector from rotating and loosening during the transfer process. This dual fixing mode of "threaded connection + pin locking" is superior to the traditional bolt connection.

[0015] 3. In this utility model, the design of the calibration block and calibration slot provides a visual calibration benchmark for the installation of the connector. During installation, the operator only needs to align the calibration slot of the limiting plate with the calibration block at the top of the mold to ensure that the positioning hole of the plug is coaxial with the limiting socket, avoiding the problem of the limiting pin not being able to be inserted due to angular deviation. This "slot-type" calibration structure does not require additional measuring tools, reducing the dependence on the operator's skill level, and is especially suitable for batch production line scenarios.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, this embodiment provides a quick disassembly and transfer device for a pulp molding mold 1; including: mold 1, with connecting holes 1011 at the four corners of the top surface of the mold 1, internal threads on the inner wall of the connecting holes 1011, and a connector 2012 screwed into the inside of the connecting holes 1011; A plug 2013 is fixedly connected to the bottom surface of the connector 2012. The plug 2013 has a cylindrical structure, and a positioning hole 2014 with bidirectional through-holes on both the front and rear sides is opened on the outer circumference of the plug 2013. A limiting plate 201 is fixedly connected to the top surface of the connector 2012, and a calibration groove 2011 is opened inside the limiting plate 201. Connecting holes 1011 are made at the four corners of the top surface of mold 1, and connecting heads 2012 are screwed on. The bottom end of the connecting head 2012 is fixed with a plug 2013, and the top end is fixed with a limiting plate 201. The top end of the limiting plate 201 is connected to the connecting rod 2 and the top plate 2015, which realizes the detachable connection between mold 1 and transfer device. The threaded engagement of plug 2013 and connecting hole 1011 provides a stable connection force. The limiting plate 201 and connecting rod 2 form a force-bearing structure, providing a reliable force point for the transfer of mold 1, which facilitates the subsequent transfer operation by cooperating with the top plate 2015, the limiting head 2016 and the transfer cross plate 3 and other components.

[0023] Among them, a connecting rod 2 is fixedly connected to the top surface of the limiting plate 201. The connecting rod 2 is a solid cylindrical structure, and a top plate 2015 is fixedly connected to the top surface of the connecting rod 2. The top plate 2015 has a circular cross-section, and a limiting head 2016 is fixedly connected to the top surface of the top plate 2015. The outer circumferential surface of the limiting head 2016 is provided with external threads. A limiting head 2016 with external threads is fixed to the top of the top plate 2015. The transfer horizontal plate 3 is sleeved on the outside of the limiting head 2016. The transfer horizontal plate 3 has a screw hole that matches the limiting head 2016. The position of the transfer horizontal plate 3 is limited by the positioning nut 301, so that the transfer horizontal plate 3 can be connected to the limiting head 2016 through the screw hole. Then, the positioning nut 301 is used to lock and fix it, thereby connecting the mold 1 with transfer equipment such as forklifts, realizing mechanized hoisting and transfer, reducing manpower input, improving transfer efficiency, and with a simple structure and firm connection.

[0024] The limiting head 2016 has a transfer plate 3 sleeved on its outer side. The transfer plate 3 is used to connect with the forklift shovel plate. The interior of the transfer plate 3 has two screw holes arranged in a linear array to match the limiting head 2016. A positioning nut 301 is screwed onto the outer side of the limiting head 2016. The positioning nut 301 is located directly above the transfer plate 3 and is used to limit the position of the transfer plate 3. The mold 1 has four limiting holes 101 on its outer side. Each pair of longitudinally adjacent limiting holes has a corresponding limiting hole. The insertion holes 101 are a set, and two sets of limiting insertion holes 101 are respectively opened on the left and right sides of the mold 1. The two sets of limiting insertion holes 101 are respectively connected to four connecting holes 1011. Limiting pins 1012 are inserted into the inside of the limiting insertion holes 101. The limiting pins 1012 match the positioning holes 2014. A calibration block 1013 matching the calibration groove 2011 is fixedly connected to the top surface of the mold 1. The calibration block 1013 is used to calibrate the position of the calibration groove 2011 and does not contact the calibration groove 2011. Four limiting holes 101 are opened on the outside of the mold 1, with two holes in each group distributed on the left and right sides and communicating with the connecting hole 1011. Limiting pins 1012 that match the positioning hole 2014 are inserted into the limiting holes 101. A calibration block 1013 that matches the calibration groove 2011 is fixed at the top of the mold 1. By inserting the limiting pins 1012 into the limiting holes 101 and the positioning hole 2014, the position of the plug 2013 in the connecting hole 1011 can be further fixed, preventing the plug 2013 from rotating or loosening during the transfer process. The calibration block 1013 and the calibration groove 2011 cooperate to quickly calibrate the installation position of the connector 2012, ensuring that all components are installed in place and improving the accuracy and reliability of the operation.

[0025] In use, first screw the connector 2012 into the four corners of the top surface of the mold 1 through the plug 2013 at its bottom end. The internal thread of the connecting hole 1011 and the external thread of the connector 2012 are used to fix it. During installation, the calibration block 1013 at the top of the mold 1 is inserted into the calibration groove 2011 of the limiting plate 201 to calibrate the orientation of the connector 2012 and ensure that the positioning hole 2014 of the plug 2013 is aligned with the limiting insertion hole 101 on the outside of the mold 1. After calibration, the calibration block 1013 is separated from the calibration groove 2011 and does not contact each other to avoid interference. When it is necessary to move the mold 1 horizontally, insert the limit pin 1012 into the limit socket 101 and the positioning hole 2014 of the plug 2013 to lock the plug 2013 to prevent rotation. The operator holds the top plate 2015 at the top of the connecting rod 2 and applies pulling force through the limit plate 201 and the connecting rod 2. The threaded connection between the connector 2012 and the connecting hole 1011 is used as the force point to move the mold 1 horizontally, avoiding direct contact with the high temperature surface of the mold 1. If hoisting is required, the transfer plate 3 is inserted into the limiting head 2016 through its screw hole, and the positioning nut 301 is rotated to press the transfer plate 3, so that it is fixed on the limiting head 2016. The forklift blade is inserted under the transfer plate 3 or the hook is hooked on the transfer plate 3. The external thread of the limiting head 2016 is connected to the screw hole of the transfer plate 3 to lift the mold 1. During the transfer process, the limiting pin 1012 continuously locks the plug 2013 to prevent the connector 2012 from loosening and falling off. After the transfer is completed, first remove the positioning nut 301 and the transfer plate 3, then pull out the limit pin 1012, and finally unscrew the connector 2012 to complete the disassembly. Repeating the operation can realize the quick replacement and transfer of mold 1.
