Description

Technical Field

[0001] The present invention belongs to the technical field of casting, and relates to an intelligent casting device for vehicle parts. Background Art

[0002] Intelligent casting reduces the labor intensity of workers and improves production efficiency through automated equipment. With the continuous progress of technology and the gradual popularization of applications, intelligent casting will become the development direction of the future casting industry. In the current production field of vehicle parts, intelligent casting is one of the important technologies.

[0003] A die casting device for an aluminum alloy vehicle frame is disclosed in a patent document with the publication number CN118558990A, which includes an upper die base, a lower die base, a die core fixed on the upper die base, a die cavity fixed on the lower die base, and guide columns fixed at the four corners of the lower die base. Guide holes are provided at the four corners of the upper die base and are slidably fitted on the four guide columns; the die cavities are two symmetrically arranged left and right, and the die cores corresponding to the die cavities are also two. A first slide rail is provided on the bottom surface of the left die cavity, and the first slide rail is slidably fitted on the left track, enabling two vehicle frames to be cast at one time, thus improving work efficiency. When the two die cavities share a solution feeding channel to feed the two die cavities simultaneously and cast the vehicle frames, through the discharging method of the two die cavities in a front-back manner, the two vehicle frames can be quickly separated at the common feeding channel, saving the feeding channel, improving the feeding efficiency of the aluminum alloy solution before casting, and also improving the casting efficiency.

[0004] However, when this casting device is in use, there are the following deficiencies. By using the discharging method of the two die cavities in a front-back manner to quickly separate the two vehicle frames at the common feeding channel, when the two die cavities move relative to each other, the port of the feeding channel is squeezed by the metal in the feeding channel, which is likely to cause wear or damage to the port of the feeding channel, affecting the quality of subsequent casting. Moreover, when the metal at the fracture moves relative to the other die cavity, it causes wear to the die cavity, affecting the cooperation of the two die cavities.

[0005] To solve the above problems, the present invention proposes an intelligent casting device for vehicle parts. Summary of the Invention

[0006] To solve the problems in the background art, the present invention proposes an intelligent casting device for vehicle parts.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows: An intelligent casting device for vehicle parts, comprising a mounting frame, an upper template, and a lower template cooperating with the upper template. The upper template is vertically movably mounted on the mounting frame, and a liquid injection hopper is provided in the middle of the upper template. There are two lower templates, and a square block is slidably mounted on the lower template. The square block is fixedly connected to a first rotating shaft, and the first rotating shaft is rotatably connected to the mounting frame. Lower die grooves are formed on both the upper and lower end faces of the lower template, and a first runner communicating with the lower die groove is formed on the lower template. The first runner cooperates with the liquid injection hopper. A linkage assembly is provided between the upper template and the first rotating shaft. When the upper template moves away from the lower template, under the action of the linkage assembly, the first rotating shaft rotates, the lower template rotates, and the two lower templates rotate in opposite directions. A top-out assembly is slidably arranged in the lower template. When the upper template moves closer to the lower template, the casting is ejected through the top-out assembly.

[0008] Further, a second runner is formed on the lower template. One end of the second runner communicates with the first runner, and the other end of the second runner communicates with the lower die groove. The cross-sectional area of the first runner is smaller than that of the second runner. The cross-section of the second runner is square, and the cross-section of the first runner is arc-shaped.

[0009] Further, the top-out assembly includes a push rod and a pressure rod. A second through hole is formed on the lower template, and the push rod is slidably arranged in the second through hole. A first through hole is formed on the lower template, and the pressure rod is slidably arranged in the first through hole. The push rod and the pressure rod are connected through a connecting member. When the upper template moves closer to the lower template, the upper template presses the pressure rod, causing the pressure rod to move downward. The pressure rod pushes the push rod downward through the connecting member, thereby ejecting the casting.

[0010] Further, the connecting member includes a sliding block, a connecting plate, and a sliding rod. The pressure rod is fixedly connected to the sliding block, the push rod is fixedly connected to the sliding rod, and the connecting plate fixedly connects the sliding block and the sliding rod. A first cavity communicating with the first through hole is formed on the lower template, and the sliding block is slidably arranged in the first cavity. A second cavity communicating the first cavity and the second through hole is formed in the lower template, the connecting plate is slidably arranged in the second cavity, and the sliding rod is slidably arranged in the second through hole.

[0011] Further, a limiting assembly is provided between the square block and the lower template. The limiting assembly includes a first clamping block and a second clamping block. The first clamping block and the second clamping block are both elastically slidably arranged on the square block. A first clamping hole and a second clamping hole are formed on the lower template. The first clamping hole cooperates with the second clamping block, and the second clamping hole cooperates with the first clamping block.

[0012] Further, an unlocking member is provided on the sliding block. The unlocking member includes a first pushing block and a second pushing block. Both the first pushing block and the second pushing block are elastically slidably arranged on the sliding block. On one side of the first pushing block and the second pushing block that are close to each other, inclined surfaces are provided; the first pushing block cooperates with the first clamping hole, and the second pushing block cooperates with the second clamping hole; when the second clamping block extends into the first clamping hole, the lower template is limited; the sliding block slides along the first cavity, so that the first pushing block is inserted into the first clamping hole and the second clamping block retracts into the square block, releasing the limitation on the lower template; when the first clamping block extends into the second clamping hole and limits the lower template, the sliding block slides along the first cavity, so that the second pushing block is inserted into the second clamping hole and the first clamping block retracts into the square block to release the limitation on the lower template.

[0013] Further, the first clamping hole and the second clamping hole are not on the same vertical plane.

[0014] In this way, when the template slides downward along the square block, it is avoided that the second clamping block extends into the second clamping hole, or the first clamping block extends into the first clamping hole, which affects the smooth progress of the casting operation.

[0015] Further, a sliding groove is provided on the lower template, and a limiting groove is provided on the inner wall of the sliding groove; a convex block is fixedly installed on the square block; the square block is slidably arranged in the sliding groove, and the convex block is slidably arranged in the limiting groove.

[0016] Further, the linkage assembly includes a rack, a gear, a worm and a worm gear; the upper template is fixedly connected with a connecting rod, and the rack is fixedly connected to the lower end of the connecting rod; an ear is fixedly connected to the mounting frame, a second rotating shaft is rotatably installed on the ear, the gear is installed on the second rotating shaft through a one-way bearing, the worm is fixedly connected to the second rotating shaft, and the worm gear is fixedly connected to the first rotating shaft and meshes with the worm.

[0017] When the upper template moves upward, the hydraulic rod drives the rack to move upward through the connecting rod. At this time, the rack does not mesh with the gear, so that the lower template has enough rotation space.

[0018] When the upper template moves upward a certain distance, the rack meshes with the gear. After that, as the upper template continues to move upward, the rack drives the gear to rotate. The gear drives the second rotating shaft to rotate through the one-way bearing, and then the worm rotates. The worm drives the worm gear to rotate, so that the first rotating shaft rotates. The first rotating shaft drives the square block to rotate, and the square block drives the lower template to rotate. When the upper template moves downward, during the downward movement of the upper template, when the rack meshes with the gear, the rack drives the gear to rotate. The gear drives the outer ring of the one-way bearing to rotate relative to the inner ring, and the second rotating shaft does not move, so that the lower template does not rotate.

[0019] Further, a hydraulic rod is fixedly installed on the mounting frame, and the output end of the hydraulic rod is vertically downward and fixedly connected to the upper template.

[0020] Compared with the prior art, the present invention has the following beneficial effects: During the process of the upper template moving upward and away from the lower template, under the action of the linkage assembly, the lower template rotates to break the casting part in the first runner, disconnecting the two castings and reducing the damage to the lower template when the two castings are disconnected. At the same time, the casting is made to face downward, facilitating the dropping of the casting.

[0021] Then, the upper template moves downward and approaches the lower template. The upper template pushes the ejection assembly, and the ejection assembly ejects the casting. And when the sliding block slides downward, the limit on the lower template is released, enabling the lower template to move downward along the square block until the first latch extends into the second latch hole, thereby making the first runner corresponding to the second lower die cavity coaxial with the first rotating shaft, preparing for the next casting and forming.

[0022] It only needs to control the up and down movement of the upper template to complete the disconnection, demolding, blanking of the casting, and the cooperation between the upper template and the lower template, with a high level of automation and improved production efficiency.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 - 18 shown, the technical solution adopted by the present invention is as follows: An intelligent casting device for vehicle accessories includes a mounting frame 1, an upper template 3 and a lower template. The upper template 3 is movably mounted up and down on the mounting frame 1. A hydraulic rod 2 is fixedly mounted on the mounting frame 1. The output end of the hydraulic rod 2 is vertically downward, and the upper template 3 is fixedly connected to the output end of the hydraulic rod 2.

[0027] There are two lower templates, and the two lower templates are symmetrically and rotatably installed on the mounting frame 1, and both of the two lower templates are arranged in cooperation with the upper template 3.

[0028] As Figure 8 , Figure 15 shown, lower die grooves 25 are formed on both the upper and lower end faces of the lower template. First runners 34 and second runners 35 are formed on both the upper and lower end faces of the lower template. One end of the second runner 35 communicates with the first runner 34 on the same side, and the other end of the second runner 35 communicates with the lower die groove 25 on the same side. A liquid injection hopper 4 that cooperates with the first runner 34 is installed on the upper template 3. When the upper template 3 and the lower template cooperate, the two corresponding first runners 34 on the two lower templates communicate. The high-temperature molten liquid is injected into the liquid injection hopper 4, and the high-temperature molten liquid flows into the lower die groove 25 through the first runner 34 and the second runner 35 for casting and forming, and then vehicle parts are cast.

[0029] After cooling and forming, the castings in the two lower die grooves 25 are connected together. Rotate the two lower templates 180 degrees and make the rotation directions of the two lower templates opposite, so that the casting part in the first runner 34 is broken off, and the castings in the two lower die grooves 25 are disconnected. And at this time, the casting is located below the lower template.

[0030] The cross-section of the second runner 35 is square, and the cross-section of the first runner 34 is arc-shaped. And the cross-sectional area of the first runner 34 is smaller than the cross-sectional area of the second runner 35. The design of the first runner 34 not only satisfies the conveyance of the high-temperature molten liquid into the two lower die grooves 25, but also enables the casting part in the first runner 34 to be broken off when the two lower templates rotate. Thus, the two castings are disconnected.

[0031] First rotating shafts 5 are rotatably installed at both the left and right ends of the mounting frame 1. Each first rotating shaft 5 is fixedly connected with a square block 14. The two square blocks 14 correspond to the two lower templates one by one, and the square block 14 is slidably connected with the corresponding lower template up and down.

[0032] Specifically, a chute 16 is formed on the lower template, and a limiting groove 17 is formed on the inner wall of the chute 16. A convex block 15 is fixedly installed on the square block 14. The square block 14 is slidably arranged in the chute 16, and the convex block 15 is slidably arranged in the limiting groove 17, so that the square block 14 is slidably and limitedly arranged in the chute 16, and the lower template slides stably along the square block 14.

[0033] A limiting component is arranged between the square block 14 and the lower template. The limiting component includes a first clamping block 18 and a second clamping block 19. Both the first clamping block 18 and the second clamping block 19 are elastically and slidably arranged on the square block 14. A first clamping block relief groove and a second clamping block relief groove are formed on the square block 14. The first clamping block 18 is slidably arranged in the first clamping block relief groove, and the second clamping block 19 is slidably arranged in the second clamping block relief groove. A first spring 20 is arranged in each of the first clamping block relief groove and the second clamping block relief groove. The first spring 20 in the first clamping block relief groove is fixedly connected between the end wall of the first clamping block relief groove and the first clamping block 18. The first spring 20 in the second clamping block relief groove is fixedly connected between the end wall of the second clamping block relief groove and the second clamping block 19.

[0034] [[ID=|3]]The lower template is provided with a first clamping hole 38 and a second clamping hole 39. The first clamping hole 38 cooperates with the second clamping block 19, and the second clamping hole 39 cooperates with the first clamping block 18. When the square block 14 is at one end of the lower template, the second clamping block 19 is inserted into the first clamping hole 38 to limit the lower template. When the square block 14 is at the other end of the lower template, the first clamping block 18 is inserted into the second clamping hole 39 to limit the lower template.

[0035] A linkage component is arranged between each first rotating shaft 5 and the upper template 3. When the upper template 3 moves upward, that is, moves away from the lower template, under the action of the linkage component, the first rotating shaft 5 rotates, and the first rotating shaft 5 drives the lower template to rotate through the square block 14.

[0036] As Figure 2 、 Figure 3 shown, the linkage component includes a rack 13, a gear 11, a worm 9 and a worm gear 6. The upper template 3 is fixedly connected with a connecting rod 12. The connecting rod 12 is arranged vertically, and the rack 13 is fixedly connected with the lower end of the connecting rod 12. An ear 7 is fixedly installed on the mounting frame 1. A second rotating shaft 8 is rotatably installed on the ear 7. The gear II is installed on the second rotating shaft 8 through a one-way bearing 10. The worm 9 is coaxially and fixedly connected with the second rotating shaft 8, and the worm gear 6 is coaxially and fixedly connected with the first rotating shaft 5. The worm gear 6 meshes with the worm 9.

[0037] When the upper template 3 moves upward, the rack 13 meshes with the gear 11. The gear 11 drives the second rotating shaft 8 to rotate through the one-way bearing 10. The second rotating shaft 8 drives the worm 9 to rotate. The worm 9 drives the worm gear 6 to rotate, and then the first rotating shaft 5 rotates. The first rotating shaft 5 drives the lower template to rotate through the square block 14. When the upper template 3 moves upward and the rack 13 meshes with the gear 11, the gear 11 drives the outer ring of the one-way bearing 10 to rotate relative to the inner ring, and the second rotating shaft 8 does not move, so that the lower template does not rotate.

[0038] A jacking component is installed on each lower template. When the upper template 3 moves downward, it acts on the jacking component. The jacking component jacks out the casting, completes the demoulding of the casting, and makes the casting fall, completing the blanking of the casting.

[0039] As Figure 9 , Figure 10 , Figure 11 shown, the ejection assembly includes a push rod 30 and a pressure rod 27. The push rod 30 and the pressure rod 27 are connected through a connecting member. The connecting member includes a sliding block 26, a connecting plate 28 and a sliding rod 29.

[0040] One end of the connecting plate 28 is fixedly connected to the sliding rod 29, and the other end of the connecting plate 28 is fixedly connected to the sliding block 26. Push rods 30 are fixedly connected to both the upper and lower ends of the sliding rod 29. Pressure rods 27 are fixedly connected to both the upper and lower ends of the sliding block 26.

[0041] A second through hole 24 is formed in the lower template, and the second through hole 24 communicates with two lower die cavities 25. A second cavity 23 and a first cavity 21 are formed in the lower template. One end of the second cavity 23 communicates with the second through hole 24, and the other end of the second cavity 23 communicates with the first cavity 21. First through holes 22 are formed in both the upper and lower ends of the first cavity 21.

[0042] The sliding rod 29 is slidably arranged in the second through hole 24, and the push rod 30 is hermetically slidably arranged in the second through hole 24. The connecting plate 28 is slidably arranged in the second cavity 23, the sliding block 26 is slidably arranged in the first cavity 21, and the pressure rod 27 is slidably arranged in the corresponding first through hole 22.

[0043] When the upper template 3 and the lower template are engaged, the pressure rod 27 at the upper end extends into the first through hole 22, and the pressure rod 27 at the lower end extends outside the lower template. The upper template 3 is moved upward, and then the lower template rotates 180 degrees around the first rotating shaft 5. After that, the upper template 3 is moved downward, and the upper template 3 presses the corresponding pressure rod 27, so that the ejection assembly ejects the casting.

[0044] An unlocking member is provided on the sliding block 26. The unlocking member includes a first push block 31 and a second push block 33. The first push block 31 and the second push block 33 are both elastically slidably arranged on the sliding block 26. Specifically, a first push block relief groove and a second push block relief groove are formed on the sliding block 26. The first push block 31 is slidably arranged in the first push block relief groove, and the second push block 33 is slidably arranged in the second push block relief groove. Second springs 32 are fixedly connected in both the first push block relief groove and the second push block relief groove, and the first push block 31 and the second push block 33 are fixedly connected to the corresponding second springs 32.

[0045] The first pushing block 31 cooperates with the first clamping hole 38, and the second pushing block 33 cooperates with the second clamping hole 39. When the second clamping block 19 extends into the first clamping hole 38 to limit the lower template, the second pushing block 33 extends into the second clamping hole 39. At this time, the elastic force of the second spring 32 is greater than that of the first spring 20. The pressing rod 27 pushes the sliding block 26 to slide along the first cavity 21, and the second pushing block 33 retracts into the second pushing block relief groove. When the first pushing block 31 and the first clamping hole 38 are opposite to each other, the first pushing block 31 extends into the first clamping hole 38 under the action of the corresponding second spring 32, and the first pushing block 31 pushes the second clamping block 19, so that the second clamping block 19 retracts into the square block 14 against the elastic force of the first spring 20. Furthermore, the limit on the lower template is released, so that the lower template can slide along the square block 14. Until the first clamping block 18 and the second clamping hole 39 are opposite to each other, the first clamping block 18 extends into the second clamping hole 39 under the action of the first spring 20 to limit the lower template.

[0046] On one side where the first pushing block 31 and the second pushing block 33 are close to each other, inclined surfaces are provided. So that the first pushing block 31 or the second pushing block 33 retracts into the sliding block 26, and the sliding block 26 can slide smoothly along the first cavity 21.

[0047] The first clamping hole 38 and the second clamping hole 39 are not on the same vertical plane. In this way, when the lower template slides downward along the square block 14, it is avoided that the second clamping block 19 extends into the second clamping hole 39, or the first clamping block 18 extends into the first clamping hole 38, which affects the smooth progress of the casting operation.

[0048] Working principle: Initially, as Figure 17 shown, the second clamping block 19 extends into the first clamping hole 38 under the action of the first spring 20, and the second pushing block 33 extends into the second clamping hole 39 under the action of the second spring 32. For the convenience of description, in this embodiment, the two lower die cavities 25 on the same lower template are respectively named the first lower die cavity 2501 and the second lower die cavity 2502. Initially, the first lower die cavity 2501 is located above the lower template, and the second lower die cavity 2502 is located below the lower template. The two lower templates are respectively named the first lower template 36 and the second lower template 37. The first lower die cavities 2501 on the first lower template 36 and the second lower template 37 both cooperate with the upper template 3. At this time, the axis of the first runner 34 corresponding to the first lower die cavity 2501 is coaxial with the first rotating shaft 5. The pressing rod 27 on the same side as the first lower die cavity 2501 extends into the lower template, and the pressing rod 27 on the same side as the second lower die cavity 2502 extends below the lower template.

[0049] High-temperature molten liquid is injected into the liquid injection hopper 4, and the high-temperature molten liquid flows into the lower die cavity 25 through the first runner 34 and the second runner 35 for casting and forming. The two castings after forming are connected together.

[0050] After the casting gradually cools down, the hydraulic rod 2 is started, and the hydraulic rod 2 drives the upper template 3 to move upward. The hydraulic rod 2 drives the rack 13 to move upward through the connecting rod 12. At this time, the rack 13 is not engaged with the gear 11, so that the lower template has sufficient space to rotate.

[0051] After the upper template 3 moves upward a certain distance, the rack 13 meshes with the gear 11. Then, as the upper template 3 continues to move upward, the rack 13 drives the gear 11 to rotate. The gear 11 drives the second rotating shaft 8 to rotate through the one-way bearing 10, and then the worm 9 rotates. The worm 9 drives the worm wheel 6 to rotate, causing the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the square block 14 to rotate, and the square block 14 drives the lower template to rotate. The lower template rotates around the first rotating shaft 5, and the rotation directions of the two lower templates are opposite, so that the casting part in the first runner 34 is broken, and the two castings are disconnected. Since the cross-sectional area of the first runner 34 is small, the casting part in the first runner 34 is easily broken. Since the first runner 34 is coaxially arranged with the first rotating shaft 5, it is beneficial to reduce the damage to the lower template when the two castings are disconnected, and helps to improve the service life of the lower template.

[0052] After the rack 13 disengages from the gear 11, the lower template rotates 180 degrees. As shown in Figure 18 At this time, the first lower die cavity 2501 is downward, the second lower die cavity 2502 is upward, and the pressure rod 27 corresponding to the second lower die cavity 2502 is located above the lower template.

[0053] After that, the hydraulic rod 2 is extended to move the upper template 3 downward. During the downward movement of the upper template 3, when the rack 13 meshes with the gear 11, the rack 13 drives the gear 11 to rotate. The gear 11 drives the outer ring of the one-way bearing 10 to rotate relative to the inner ring, and the second rotating shaft 8 does not move, so that the lower template does not rotate.

[0054] The upper template 3 presses the pressure rod 27 corresponding to the second lower die cavity 2502. At this time, since the lower template is limited by the second clamping block 19, the lower template cannot move downward. The second push block 33 retracts from the second clamping hole 39 into the sliding block 26. The sliding block 26 moves downward along the first cavity 21, the connecting plate 28 moves downward in the second cavity 23, the sliding rod 29 moves downward, and the sliding rod 29 pushes the casting in the first lower die cavity 2501 downward through the push rod 30, pushing out the casting in the first lower die cavity 2501, completing the demoulding of the casting and causing the casting in the first lower die cavity 2501 to fall.

[0055] After the pressure rod 27 corresponding to the second lower die groove 2502 retracts into the lower template, the pressure rod 27 corresponding to the first lower die groove 2501 extends below the lower template. At this time, the ejection assembly cannot continue to move downward, and at this time, the first push block 31 is opposite to the first locking hole 38. Under the action of the second spring 32, the first push block 31 extends into the first locking hole 38, and the first push block 31 pushes the second locking block 19 in the first locking hole 38 back into the square block 14, thereby releasing the limit on the lower template.

[0056] After that, the upper template 3 continues to move downward. The upper template 3 pushes the lower template to move downward, and the lower template moves downward along the square block 14 until the first locking block 18 is opposite to the second locking hole 39. Under the action of the first spring 20, the first locking block 18 extends into the second locking hole 39 to limit the lower template. At this time, the first runner 34 corresponding to the second lower die groove 2502 is coaxial with the first rotating shaft 5. At this time, the second lower die groove 2502 on the sliding block 26 and the pressure rod 27 cooperates with the upper template 3.

[0057] When the lower template moves downward along the square block 14, since the second locking hole 39 and the first locking hole 38 are not on the same vertical plane, it is avoided that the second locking block 19 is inserted into the second locking hole 39, so that the lower template can continue to move downward until the first locking block 18 is opposite to the second locking hole 39, so that the first locking block 18 extends into the second locking hole 39, and further makes the first runner 34 corresponding to the second lower die groove 2502 coaxial with the first rotating shaft 5.

[0058] Similarly, high-temperature liquid is injected into the liquid injection hopper 4, and the high-temperature liquid flows into the second lower die groove 2502 through the first runner 34 and the second runner 35 for casting and forming.

[0059] Accordingly, in the process of the upper template 3 moving upward and away from the lower template, under the action of the linkage assembly, the lower template rotates to break the casting part in the first runner 34, disconnect the two castings, and at the same time make the casting face downward to facilitate the casting to fall. Then the upper template 3 moves downward and close to the lower template. The upper template 3 pushes the ejection assembly, and the ejection assembly ejects the casting. And when the sliding block 26 slides downward, the limit on the lower template is released, so that the lower template moves downward along the square block 14 until the first locking block 18 extends into the second locking hole 39, and further makes the first runner 34 corresponding to the second lower die groove 2502 coaxial with the first rotating shaft 5, preparing for the next casting and forming.

[0060] When the upper template 3 moves upward, the separation of the two castings is completed through the linkage component, and at the same time, preparations are made for the ejection of the castings. When the upper template 3 moves downward, the upper template 3 presses the ejection component, thereby ejecting the casting and preparing for the next casting operation, improving the automation level of casting and being beneficial to improving the working efficiency of casting. Only by controlling the up and down movement of the upper template 3 can the disconnection, demoulding, blanking of the casting and the cooperation between the upper template 3 and the lower template be completed, with a high automation level and an improved production efficiency.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
