Description

Technical Field

[0001] This invention relates to the field of lead processing technology, and more specifically, to a multifunctional lead brick extrusion device with interchangeable molds. Background Technology

[0002] In modern industrial production, lead bricks are widely used in fields such as medical and nuclear energy due to their excellent radiation protection properties. The production quality and efficiency of lead bricks are directly related to the development of related industries. Among them, molds occupy a core position in the lead brick production process, and their rational design has a significant impact on the quality and production efficiency of lead bricks.

[0003] The fixed molds used in traditional lead brick extrusion equipment have become a bottleneck restricting the development of the industry. Due to the great differences in the specification requirements of lead bricks in different application scenarios, such as lead bricks for medical protection, which may need to be customized with specific sizes and shapes according to the radiation intensity and protection range of different departments, while in nuclear energy facilities, the specifications of lead bricks need to fit the equipment layout and protection standards. However, fixed molds can only be adapted to a single or limited number of lead brick specifications. When enterprises need to switch to producing lead bricks of different specifications, they have to face the thorny problem of mold replacement.

[0004] Replacing a traditional fixed mold involves a lengthy process, from shutdown preparation, removal of the old mold, to installation of the new mold, resulting in idle equipment, production stoppage, and economic losses. Therefore, we propose a multi-functional, interchangeable-mold lead brick extrusion device. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional lead brick extrusion device with interchangeable molds, which aims to solve the problem that in the existing technology, the entire process of changing molds is time-consuming, resulting in idle equipment, production stagnation, and economic losses.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a multifunctional lead brick extrusion device with replaceable molds, comprising a base, a plurality of guide frames fixedly connected to the top of the base, a pair of symmetrically arranged extrusion plates slidably connected to the outer wall of the guide frames, the bottom of the lower extrusion plate being fixedly connected to the top of the base, a top cover being fixedly connected to the top of the guide frames, a hydraulic rod being fixedly connected to the bottom of the top cover, the other end of the hydraulic rod being fixedly connected to the top of the upper extrusion plate, a pair of piston cylinders being provided on the top of the base, corresponding molds being provided on opposite sides of the extrusion plates, and an adjustment mechanism for fixing and removing the molds being provided inside each extrusion plate.

[0007] Preferably, the adjusting mechanism includes a receiving cavity, which is respectively opened on opposite sides between the extrusion plates. An adjusting seat is slidably connected to the inner wall of the receiving cavity. The interior of the adjusting seat is hollow, and a groove communicating with the interior is opened at the end of the adjusting seat. A pin is slidably connected to the inner wall of the groove. The two ends of the pin are respectively inserted into the adjusting seat and extend to the outside of the receiving cavity. A first spring is provided at the end of the pin inserted into the adjusting seat. The other end of the first spring is fixedly connected to the inner end wall of the adjusting seat. A second spring is fixedly connected to the end wall of the adjusting seat. The other end of the second spring is fixedly connected to the inner end wall of the receiving cavity. A pair of convex grooves are opened on the outer wall of the extrusion plate and pass through it. A pair of convex plates corresponding to the convex grooves are fixedly connected to the outer wall of the mold. A slot is opened on the side of the mold near the extrusion plate. The air outlet of the piston cylinder communicates with the interior of the receiving cavity. A limiting component for limiting the position of the pin is provided in the adjusting seat.

[0008] Preferably, the limiting component includes multiple limiting blocks, which are uniformly and fixedly connected to the outer wall of the insert located inside the adjusting seat. Multiple limiting members are fixedly connected to the inner wall of the adjusting seat. Each limiting member has a long plate structure and is located between the limiting blocks. Multiple inclined guide members are fixedly connected to the inner end wall of the adjusting seat. Both ends of each limiting block are tapered structures. The inclined guide members guide the limiting blocks as they move. One end of each limiting member near the guide member is recessed to form a locking portion, which engages with the end of the limiting member after it moves.

[0009] Preferably, each of the extrusion plates has a connecting block fixedly connected to its outer wall. The inner wall of the connecting block located on the lower side is fixedly connected to the lower outer wall of the piston cylinder, and the inner wall of the connecting block located on the upper side is slidably connected to the upper inner wall of the piston cylinder. The outer wall of the connecting block located on the upper side is provided with a push rod that passes through it and abuts against the upper outer wall of the piston cylinder, and the push rod is threadedly connected to the connecting block.

[0010] Preferably, the outer wall of the extrusion plate is fixedly connected to an exhaust pipe that is linked to the interior of the storage cavity. A section of the exhaust pipe away from the storage cavity is hinged with a symmetrically arranged sealing door by a torsion spring. The sealing door is used to seal the exhaust pipe.

[0011] Preferably, one end of the insert post is inserted into the adjusting seat and a rotatable turntable is embedded therein, and the other end of the turntable is fixedly connected to the end of the first spring.

[0012] Preferably, the outer edge of the end of the insert away from the adjusting seat is arc-shaped and the outer edge of the end of the insert is formed into a pushing part after it is contracted.

[0013] Preferably, a storage plate is fixedly connected to the outer wall of the extrusion plate located on the lower side, and the two sides of the storage plate are bent vertically upward to form an enclosing portion.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention, by setting up a base, guide frame, extrusion plate, top cover, hydraulic rod, piston cylinder, mold, and adjustment mechanism, utilizes the connection design between the piston cylinder and the receiving cavity to achieve rapid operation of mold fixing and disassembly. When changing the mold, the operator only needs to control the air output of the piston cylinder to use the gas pressure to drive the adjustment seat and the insert, quickly completing the mold disassembly and installation. Compared with the long time spent on traditional mold replacement, this equipment can shorten the mold replacement time, greatly reduce the idle time of the equipment due to mold replacement, effectively avoid production stoppage, reduce economic losses, and significantly improve production efficiency.

[0016] 2. In this invention, through the synergistic effect of the limiting block, limiting component, and guide component, the insert can be effectively limited after it is inserted into the mold slot. During the movement of the limiting block, it is guided by the guide component and accurately engages with the locking part of the limiting component, ensuring that the insert will not loosen due to external force or equipment vibration. This stable fixing method enables the mold to remain stable during the lead brick extrusion process, avoiding quality problems such as lead brick size deviation and surface defects caused by mold shaking or displacement.

[0017] 3. In this invention, when the receiving cavity needs to use gas pressure to push the adjusting seat to move in order to complete the fixing or dismantling of the mold, the sealing door can effectively prevent the gas from flowing out quickly. If the gas is discharged quickly without restraint, the gas pressure in the receiving cavity will drop rapidly, resulting in insufficient gas pressure to push the adjusting seat to move smoothly, thus affecting the smooth progress of the mold replacement process. The presence of the sealing door maintains the stability of the gas pressure in the receiving cavity, ensuring that the adjusting seat can accurately complete the extension and retraction action under continuous and appropriate gas pressure, ensuring the stable operation of the core function of the equipment, and greatly improving the reliability of the equipment in the mold replacement operation.

[0018] 4. In this invention, the connecting block located on the upper side is slidably connected to the piston cylinder, and the abutment rod passes through the connecting block and abuts against the upper outer wall of the piston cylinder. By rotating the abutment rod, the tightness of its abutment against the piston cylinder can be changed, thereby controlling the operation and stopping of the piston cylinder and preventing the mold from unlocking during normal use, which would affect the stability of lead brick production.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Example 1

[0027] like Figure 1-4 As shown, a multifunctional lead brick extrusion device with replaceable molds includes a base 1. Multiple guide frames 2 are fixedly connected to the top of the base 1. A pair of symmetrically arranged extrusion plates 3 are slidably connected to the outer wall of the guide frames 2. The bottom of the lower extrusion plate 3 is fixedly connected to the top of the base 1. A top cover 4 is fixedly connected to the top of the guide frames 2. A hydraulic rod 5 is fixedly connected to the bottom of the top cover 4. The other end of the hydraulic rod 5 is fixedly connected to the top of the upper extrusion plate 3. A pair of piston cylinders 6 are provided on the top of the base 1. Corresponding molds 7 are provided on opposite sides of the extrusion plates 3. Each extrusion plate 3 is provided with an adjustment mechanism for fixing and removing the molds 7.

[0028] The adjustment mechanism includes a receiving cavity 8, which is respectively opened on opposite sides between the extrusion plates 3. An adjustment seat 9 is slidably connected to the inner wall of the receiving cavity 8. The interior of the adjustment seat 9 is hollow, and a groove 10 communicating with the interior is opened at the end of the adjustment seat 9. A pin 11 is slidably connected to the inner wall of the groove 10. The two ends of the pin 11 are respectively inserted into the adjustment seat 9 and extend to the outside of the receiving cavity 8. A first spring 12 is provided at one end of the pin 11 inserted into the adjustment seat 9, and the other end of the first spring 12 is connected to the adjustment seat 9. The inner end wall of the adjusting seat 9 is fixedly connected to the second spring 13. The other end of the second spring 13 is fixedly connected to the inner end wall of the receiving cavity 8. The outer wall of the extrusion plate 3 is provided with a pair of convex grooves 14 that pass through it. The outer wall of the mold 7 is fixedly connected with a pair of convex plates 15 corresponding to the convex grooves 14. The mold 7 is provided with a slot 16 on the side near the extrusion plate 3. The air outlet of the piston cylinder 6 is connected to the interior of the receiving cavity 8. The adjusting seat 9 is provided with a limiting component for limiting the insertion post 11.

[0029] The limiting assembly includes multiple limiting blocks 17, which are uniformly and fixedly connected to the outer wall of the insert 11 located inside the adjusting seat 9. Multiple limiting members 18 are fixedly connected to the inner wall of the adjusting seat 9. The limiting members 18 are long plate-shaped structures and are located between the limiting blocks 17. Multiple inclined guide members 19 are fixedly connected to the inner end wall of the adjusting seat 9. Both ends of the limiting blocks 17 are tapered structures. The inclined guide members 19 guide the limiting blocks 17 when they move. The end of the limiting member 18 near the guide member 19 is recessed to form a locking part 20. The locking part 20 engages with the end of the limiting member 18 after it moves.

[0030] Specifically, when installing mold 7, the operator first aligns the convex plate 15 on mold 7 with the convex groove 14 on the outer wall of extrusion plate 3, and then slowly pushes mold 7 to make it fit tightly against extrusion plate 3. During this process, the movement of mold 7 will gradually approach the insertion post 11, preparing for the subsequent action of insertion post 11. As mold 7 continues to move, the relative movement between extrusion plate 3 and mold 7 begins to exert a squeezing effect on insertion post 11. One end of insertion post 11 is located in the sliding groove 10 at the end of adjusting seat 9. Sliding within the slide groove 10 and compressed by the mold 7, the insert 11 moves along the slide groove 10 into the adjusting seat 9. Since a first spring 12 is provided at one end of the insert 11 that inserts into the adjusting seat 9, the first spring 12 is compressed. Multiple limiting blocks 17 are evenly fixed to the outer wall of the insert 11. When the insert 11 moves into the adjusting seat 9, the limiting blocks 17 move accordingly and interact with the limiting member 18 and the guide member 19. The limiting member 18 is a long plate structure distributed among the limiting blocks 17. Multiple inclined guides 19 are fixedly connected to the inner end wall of the section seat 9. The two ends of the limiting block 17 are tapered. When the limiting block 17 contacts the guides 19, the inclined guides 19 begin to guide the limiting block 17. Due to the inclination angle of the guides 19, the limiting block 17 drives the insert 11 to rotate under the action of the guides 19. As the mold 7 continues to move, the insert 11 rotates a certain angle under the action of the limiting block 17. Under the elastic force of the first spring 12, the end of the insert 11... The adjusting seat 9 extends out and inserts into the slot 16 opened on the side of the mold 7 near the extrusion plate 3. At this time, the limiting block 17, guided by the guide 19, moves to the locking part 20 formed by the recess of the limiting part 18 near the guide 19 and engages with it. This locking structure firmly limits the insertion post 11, ensuring that the insertion post 11 will not be dislodged from the slot 16 of the mold 7 due to external force or equipment vibration, thereby achieving stable fixation of the mold 7 on the extrusion plate 3 and laying the foundation for subsequent lead brick extrusion work.

[0031] When mold 7 needs to be disassembled, the piston cylinder 6 is driven by the stamping plate to push gas into the receiving cavity 8. The gas pressure in the receiving cavity 8 rises rapidly, and the high-pressure gas exerts a pushing force on the adjusting seat 9, causing the adjusting seat 9 to move away from mold 7 along the inner wall of the receiving cavity 8. The movement of the adjusting seat 9 causes the insert 11 to move relative to the adjusting seat 9. The limiting block 17 on the outer wall of the insert 11 moves again between the limiting members 18. Similar to when mold 7 is installed, the limiting block 17 contacts the guide member 19 during the movement. The inclined guide member 19 guides the limiting block 17 again. The limiting block 17 drives the insert 11 to rotate, causing the limiting block 17 to disengage from the locking part 20 of the limiting member 18. As the adjusting seat 9 continues to move, the insert 11 further retracts within the adjusting seat 9, and then the gas inside the receiving cavity 8 is discharged. The gas pressure in the receiving cavity 8 decreases, and the adjusting seat 9 moves along the inner wall of the receiving cavity 8 under the elastic force of the second spring 13. The inner wall of the storage cavity 8 is reset towards the mold 7, returning to the initial position to prepare for the replacement of the new mold 7. The operator aligns the convex plate 15 of the new mold 7 with the convex groove 14 of the extrusion plate 3, and then pushes the new mold 7 close to the extrusion plate 3. During the movement, the edge of the new mold 7 exerts a pushing force on the old mold 7 that needs to be disassembled. During the pushing process, the edge of the slot 16 of the old mold 7 contacts the end of the insert 11 and pushes the insert 11, causing the insert 11 to move into the adjusting seat 9 again. During this process, the insert 11 rotates again under the action of the limiting block 17 and the guide 19. When the new mold 7 moves to the appropriate position, the end of the insert 11 is inserted into the slot 16 of the new mold 7 under the elastic force of the first spring 12. At the same time, the limiting block 17 engages again with the engaging part 20 of the limiting part 18, completing the fixation of the new mold 7, thereby realizing the replacement of the mold 7.

[0032] Furthermore, the outer wall of the extrusion plate 3 is fixedly connected with a connecting block 21. The inner wall of the connecting block 21 located on the lower side is fixedly connected to the lower outer wall of the piston cylinder 6, and the inner wall of the connecting block 21 located on the upper side is slidably connected to the upper inner wall of the piston cylinder 6. The outer wall of the connecting block 21 located on the upper side is provided with a push rod 22 that passes through it and abuts against the upper outer wall of the piston cylinder 6, and the push rod 22 is threadedly connected to the connecting block 21.

[0033] Specifically, the connecting block 21 located on the upper side is slidably connected to the piston cylinder 6, and the push rod 22 passes through the connecting block 21 and abuts against the upper outer wall of the piston cylinder 6. By rotating the push rod 22, the tightness of its abutment against the piston cylinder 6 can be changed, thereby controlling the operation and stopping of the piston cylinder 6 and preventing the mold 7 from unlocking during normal use, which would affect the stability of lead brick production.

[0034] Furthermore, the outer wall of the extrusion plate 3 is fixedly connected to an exhaust pipe 23 that is linked to the inside of the storage cavity 8. A section of the exhaust pipe 23 away from the storage cavity 8 is hinged with a symmetrically arranged sealing door 24 by a torsion spring. The sealing door 24 is used to seal the exhaust pipe 23.

[0035] Specifically, the exhaust pipe 23 provides a channel for venting gas into the receiving chamber 8. It should be noted that since the exhaust efficiency of the exhaust pipe 23 is insufficient to quickly and completely expel the gas injected into the piston cylinder 6, the exhaust pipe 23 will not affect the movement of the adjusting seat 9. However, when the receiving chamber 8 needs to use gas pressure to move the adjusting seat 9 to complete the fixing or removal of the mold 7, the sealing door 24 can effectively prevent the rapid outflow of gas. If the gas is discharged rapidly without restraint, the gas pressure in the receiving chamber 8 will drop rapidly, resulting in insufficient gas pressure to drive the adjusting seat 9 to move smoothly, thus affecting the smooth progress of the mold 7 replacement process. The presence of the sealing door 24 maintains the stability of the gas pressure in the receiving chamber 8, ensuring that the adjusting seat 9 can accurately complete the extension and retraction movements under continuous and appropriate gas pressure, ensuring the stable operation of the core functions of the equipment, and greatly improving the reliability of the equipment in the mold 7 replacement operation.

[0036] Furthermore, one end of the insert post 11 is inserted into the adjusting seat 9 and a rotatable turntable 25 is embedded therein, and the other end of the turntable 25 is fixedly connected to the end of the first spring 12.

[0037] Specifically, by setting the turntable 25, the insertion post 11 can be prevented from directly contacting the first spring 12, thereby ensuring the normal rotation effect of the insertion post 11.

[0038] Furthermore, the outer edge of the end of the insert 11 away from the adjusting seat 9 is arc-shaped and shrinks, forming a pushing part 26 after the outer edge of the end of the insert 11 shrinks.

[0039] Specifically, the pushing part 26 formed by the insert post 11 allows the edge of the mold 7 and the edge of the slot 16 to push the pushing part 26, which is guided by the pushing part 26, thereby ensuring the normal, stable and effective movement of the insert post 11.

[0040] Furthermore, a storage plate 27 is fixedly connected to the outer wall of the extrusion plate 3 located on the lower side, and the two sides of the storage plate 27 are bent vertically upward to form an enclosing part 28.

[0041] Specifically, the storage plate 27 can store the old template that has been pushed away from the stamping plate. The storage plate 27 surrounds the template by the surrounding part 28, thereby preventing the mold 7 from falling off and ensuring continuity when changing the mold 7.

[0042] Working Principle: This embodiment provides a multifunctional lead brick extrusion device with replaceable molds. When installing the mold 7, the operator first aligns the convex plate 15 on the mold 7 with the convex groove 14 on the outer wall of the extrusion plate 3, and then slowly pushes the mold 7 to make the mold 7 fit tightly against the extrusion plate 3. During this process, the movement of the mold 7 will gradually approach the insertion post 11, preparing for the subsequent action of the insertion post 11. As the mold 7 continues to move, the relative movement between the extrusion plate 3 and the mold 7 begins to exert a squeezing effect on the insertion post 11. One end of the insert 11 is located in the groove 10 at the end of the adjusting seat 9 and can slide within the groove 10. After being squeezed by the mold 7, the insert 11 moves along the groove 10 into the adjusting seat 9. Since the end of the insert 11 inserted into the adjusting seat 9 is provided with a first spring 12, the first spring 12 is compressed at this time. Multiple limiting blocks 17 are evenly fixed on the outer wall of the insert 11. When the insert 11 moves into the adjusting seat 9, the limiting blocks 17 move accordingly and interact with the limiting member 18 and the guide member 19. The limiting member 18 is a long plate structure. Distributed between the limiting blocks 17, the inner end wall of the adjusting seat 9 is fixedly connected with multiple inclined guides 19. The two ends of the limiting blocks 17 are tapered. When the limiting blocks 17 contact the guides 19, the inclined guides 19 begin to guide the limiting blocks 17. Due to the inclination angle of the guides 19, the limiting blocks 17 drive the inserts 11 to rotate under the action of the guides 19. As the mold 7 continues to move, the inserts 11 rotate a certain angle under the action of the limiting blocks 17, and the end of the inserts 11 is then... Under the action of elastic force, it extends out from the adjusting seat 9 and is inserted into the slot 16 opened on the side of the mold 7 near the extrusion plate 3. At this time, under the guidance of the guide 19, the limiting block 17 moves to the locking part 20 formed by the recess of the limiting part 18 near the guide 19 and locks with it. This locking structure firmly limits the insertion post 11, ensuring that the insertion post 11 will not be dislodged from the slot 16 of the mold 7 due to external force or equipment vibration, thereby realizing the stable fixation of the mold 7 on the extrusion plate 3 and laying the foundation for the subsequent lead brick extrusion work.

[0043] When mold 7 needs to be disassembled, the piston cylinder 6 is driven by the stamping plate to push gas into the receiving cavity 8. The gas pressure in the receiving cavity 8 rises rapidly, and the high-pressure gas exerts a pushing force on the adjusting seat 9, causing the adjusting seat 9 to move away from mold 7 along the inner wall of the receiving cavity 8. The movement of the adjusting seat 9 causes the insert 11 to move relative to the adjusting seat 9. The limiting block 17 on the outer wall of the insert 11 moves again between the limiting members 18. Similar to when mold 7 is installed, the limiting block 17 contacts the guide member 19 during the movement. The inclined guide member 19 guides the limiting block 17 again. The limiting block 17 drives the insert 11 to rotate, causing the limiting block 17 to disengage from the locking part 20 of the limiting member 18. As the adjusting seat 9 continues to move, the insert 11 further retracts within the adjusting seat 9, and then the gas inside the receiving cavity 8 is discharged. The gas pressure in the receiving cavity 8 decreases, and the adjusting seat 9 moves along the inner wall of the receiving cavity 8 under the elastic force of the second spring 13. The inner wall of the storage cavity 8 is reset towards the mold 7, returning to the initial position to prepare for the replacement of the new mold 7. The operator aligns the convex plate 15 of the new mold 7 with the convex groove 14 of the extrusion plate 3, and then pushes the new mold 7 close to the extrusion plate 3. During the movement, the edge of the new mold 7 exerts a pushing force on the old mold 7 that needs to be disassembled. During the pushing process, the edge of the slot 16 of the old mold 7 contacts the end of the insert 11 and pushes the insert 11, causing the insert 11 to move into the adjusting seat 9 again. During this process, the insert 11 rotates again under the action of the limiting block 17 and the guide 19. When the new mold 7 moves to the appropriate position, the end of the insert 11 is inserted into the slot 16 of the new mold 7 under the elastic force of the first spring 12. At the same time, the limiting block 17 engages again with the engaging part 20 of the limiting part 18, completing the fixation of the new mold 7, thereby realizing the replacement of the mold 7.

[0044] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
