Description

Technical Field

[0001] The invention relates to the technical field of automobile steering gear processing, in particular to a shell die-casting molding device for automobile steering gear production. Background Art

[0002] The automotive steering gear housing die-casting machine is a high-precision, high-efficiency casting system used to produce automotive steering system housing components. Using high-pressure casting technology, the machine injects molten metal into a mold, rapidly shapes it, and cools it, ensuring dimensional accuracy and surface quality. It is widely used in automotive parts manufacturing to improve production efficiency and reduce costs.

[0003] Chinese patent publication number CN210848270U discloses a die-casting mold for an automobile steering gear that facilitates demolding. The mold comprises a mold cavity, a mold cover, a square cylinder, bars, a column, a guide groove, a slider, a first cylinder, a base plate, a second cylinder, and a vibrator. This utility model features a rational design. By activating all first and second cylinders (1) and simultaneously extending them, the two mold cover plates and two mold cavities are rapidly disassembled in all directions, exposing the molded part quickly for processing, achieving rapid demolding and simultaneously enabling rapid mold closing. By activating the vibrator and varying the vibration amplitude via corresponding control elements, the molded part is easily separated from the mold cavity, and demolding operations can be performed simultaneously, increasing demolding speed.

[0004] However, the current die-casting molding equipment has the following problems: after the die-casting molding equipment uses an external manipulator to remove the molded automobile steering gear, metal impurities are likely to remain inside the die-casting mold. The presence of metal impurities causes the surface of the die-casting mold to be uneven or have irregular protrusions, thereby affecting the subsequent uniform spraying of the release agent. The release agent cannot evenly cover the entire mold surface, which may lead to poor demolding effect and mold adhesion, affecting the quality of the parts. Therefore, we propose a shell die-casting molding equipment for automobile steering gear production. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a housing die-casting molding device for producing automobile steering gears, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A shell die-casting molding equipment for automobile steering gear production, including a processing table, a fixed mold assembly is provided on one side of the top of the processing table, a movable mold assembly is provided on the other side of the top of the processing table, a spraying device is fixedly provided on the bottom of the inner wall of the processing table, and the spraying device includes a motor 1 fixed to the bottom of the inner wall of the processing table, two mountain-shaped rods fixed to the bottom of the inner wall of the processing table, the mountain-shaped rods are located on both sides of the motor 1, a screw is fixed on the top of the output end of the motor 1, the external thread of the screw is connected to a U-shaped push plate, and the U-shaped push plate is slidably mounted on the mountain The U-shaped push plate is fixed with an H-shaped frame on the outside of the middle support rod of the H-shaped rod, and atomizing nozzle tubes are rotatably installed on both sides of the H-shaped frame. A number of brushes are evenly fixed on the outer circumference of the atomizing nozzle tube. A through hole for the H-shaped frame to pass through is opened on the top of the processing table. The molds corresponding to the fixed mold assembly and the movable mold assembly are located on the movement track of the brushes. A spraying assembly for injecting a release agent into the atomizing nozzle tube is provided at the bottom of the inner wall of the processing table. The spraying assembly includes a release agent box, which is fixed to the bottom of the inner wall of the processing table. A pump is fixed on the top of the release agent box. The top of the pump A folding tube is fixed, and a guide tube is fixed at one end of the folding tube away from the pump. The guide tube is fixed on the front side of the H-shaped frame, and the guide tube is rotatably connected to the front sides of the two atomizing nozzle tubes. The interiors of the two atomizing nozzle tubes are communicated with the interiors of the guide tubes. A driving assembly for driving the atomizing nozzle tube to rotate is provided on the rear side of the atomizing nozzle tube, and the driving assembly includes a second motor, a first pulley, and two second pulleys. The second motor is fixed to the rear outer wall of the U-shaped push plate, the first pulley is fixed to the rear output end of the second motor, and the two second pulleys are respectively fixed to the rear sides of the two atomizing nozzle tubes. The first pulley is connected to the two pulleys. The two pulleys are connected by belt transmission, the motor drives the pulley one to rotate, the pulley one drives the two pulleys two to rotate through the belt, the two pulleys two drive the two atomizing nozzle tubes to rotate, the two atomizing nozzle tubes drive the brush to rotate, and at the same time the motor drives the screw to rotate, the screw drives the U-shaped push plate to move upward along the outside of the mountain-shaped rod, the U-shaped push plate pushes the H-shaped frame to drive the two atomizing nozzle tubes to move upward, during this process, the staff starts the pump, the pump extracts the release agent in the release agent box and transmits it to the atomizing nozzle tube through the folding tube and the guide tube, so that the atomizing nozzle tube will spray the release agent in atomization while rotating.

[0007] According to the above technical solution, a guide device is provided at the H-shaped frame, and the guide device includes two elastic arc plates, and the two elastic arc plates are respectively fixed on both sides of the inner wall of the H-shaped frame. When the atomizing nozzle tube sprays out the release agent into atomization, the elastic arc plate will guide the atomization of the release agent sprayed out from the atomizing nozzle tube toward the mold direction of the fixed mold assembly and the movable mold assembly. The inner walls of the two elastic arc plates are both laterally slidably installed with arc slides, and a plurality of arc strips are evenly and equidistantly fixed on the side of the two arc slides away from the elastic arc plates. The middle parts of the two elastic arc plates are provided with strip grooves, and the strip grooves of the elastic arc plates are both laterally slidably installed with two L-shaped push rods, and the L-shaped push rods are slidably connected to the outer wall of the arc slide. The L-shaped push rod is pressed against the bottom surface of the brush and the arc block is fixed on the outer wall of the brush, so that the brush can be easily moved.

[0008] The front side of the two curved bars on the front side are fixed with a resistance rod, and the front top side of the H-shaped frame is fixed with a protrusion plate on both sides, and the rear side of the protrusion plate is evenly and equidistantly fixed with a number of semi-arc protrusions, and the front side of the resistance rod is semicircular, and the semi-arc protrusions of the protrusion plate are located on the semi-circular movement trajectory of the resistance rod. At the same time, when the L-shaped push rod pushes the curved slide plate and the curved bar toward the brush, the curved slide plate drives the resistance rod to move accordingly. When the semicircle of the resistance rod moves to the semi-arc protrusion position of the protrusion plate, the semi-arc protrusion of the protrusion plate pushes the semi-circular shape of the resistance rod to drive the resistance rod to displace, and the curved bar on the front side of the resistance rod moves laterally, and the curved bar on the front side drives the curved slide plate to displace along the outside of the L-shaped push rod, and the curved slide plate drives the curved bar to displace, so that the curved slide plate and the curved bar will be displaced in the horizontal direction while approaching the brush.

[0009] According to the above technical solution, the top of the H-shaped frame is provided with an anti-residue device, and the anti-residue device includes two triangular plates and two bidirectional elastic telescopic rods. The two bidirectional elastic telescopic rods are respectively fixed to the top front side and the top rear side of the H-shaped frame, and the telescopic ends of both sides of the two bidirectional elastic telescopic rods are fixed with T-shaped rods. The two T-shaped rods on one side are fixed with a push column 1 on the side away from the center of the H-shaped frame, and the two T-shaped rods on one side are fixed with a push column 2 on the side close to the center of the H-shaped frame. The two triangular plates are respectively fixed between the two sides of the two mountain-shaped rods, and the push column 1 is in contact with the outer wall of the elastic arc plate. The push column 2 is in contact with the inclined surface of the triangular plate. Every time the H-shaped frame moves downward, the H-shaped frame drives the push column 2 to move downward through the bidirectional elastic telescopic rod. At this time, the inclined surface of the triangular plate pushes the push column 2 to drive the T-shaped rod to move away from the center of the H-shaped frame. The push column 1 is against the outer wall of the elastic arc plate again, thereby causing the outer wall above the elastic arc plate to bend and deform. At this time, the elastic arc plate is on the movement trajectory of the brush. Since the curved part of the elastic arc plate will hinder the movement direction of the brush, as the atomizing nozzle tube continues to drive the brush to rotate, the rotation of the brush will cause the brush to hit the curved part of the elastic arc plate.

[0010] The present invention provides a housing die-casting device for producing automobile steering gears. It has the following beneficial effects: (1) The present invention arranges a spraying device so that the motor 2, the pulley 1, the pulley 2, the atomizing nozzle tube, the motor 1, the screw, the U-shaped push plate, the mountain-shaped rod, the H-shaped frame, the pump, the release agent box, the folding tube, and the guide tube cooperate to drive the atomizing nozzle tube to rotate and spray the release agent in atomized form, thereby ensuring that the release agent is evenly covered on the mold surface of the fixed mold assembly and the movable mold assembly. At the same time, the brush will brush the mold surface of the fixed mold assembly and the movable mold assembly. The brush can remove metal impurities on the mold surface and ensure that the mold surface is clean and smooth, which helps to improve the quality of the product. In addition, the brushing of the brush helps to evenly distribute the release agent, ensuring that each part of the mold is fully coated, thereby avoiding incomplete demoulding due to lack of release agent in certain areas.

[0011] (2) The present invention sets a guide device so that the elastic arc plate guides the atomized release agent sprayed from the atomizing nozzle tube toward the mold direction of the fixed mold assembly and the movable mold assembly, thereby ensuring that the atomized spray of the release agent is accurately sprayed toward the mold surface, avoiding the diffusion and waste of the release agent, thereby helping the release agent to be concentrated and evenly covered on the mold surface, thereby enhancing the demoulding effect; at the same time, the H-shaped frame, the elastic arc plate, the L-shaped push rod, and the mountain-shaped rod cooperate to drive the arc-shaped slide plate and the arc-shaped bar to squeeze and scatter the brush, and the scattering of the brush helps to more effectively make the contact surface between the release agent and the mold during the process of applying the release agent. This effect can improve the distribution efficiency of the release agent and ensure that every part of the mold is properly coated with the release agent; at the same time, the L-shaped push rod, the arc-shaped slide plate, the arc-shaped bar, the resistance rod, and the bump plate cooperate to drive the arc-shaped slide plate and the arc-shaped bar toward the brush while also displacing in the horizontal direction, thereby allowing the arc-shaped bar to further squeeze and scatter the brush.

[0012] (3) The present invention sets an anti-residue device so that the H-shaped frame, the bidirectional elastic telescopic rod, the push column 2, the triangular plate, and the T-shaped rod cooperate to drive the push column 1 to bend and deform against the outer wall above the elastic arc plate. At this time, the elastic arc plate is on the movement trajectory of the brush. Since the curved portion of the elastic arc plate will hinder the movement direction of the brush, as the atomizing nozzle tube continues to drive the brush to rotate, the rotation of the brush will cause the brush to hit the curved portion of the elastic arc plate. The impact force of the impact helps to loosen and remove the residual desulfurizer on the brush, reducing the possibility of the desulfurizer accumulating on the brush, thereby avoiding the problem that the residual release agent on the brush is not cleaned in time, resulting in the release agent undergoing chemical changes due to oxidation, pollution, etc., losing its proper lubrication and demoulding properties, and affecting the quality of the subsequent die-casting process.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] See also Figures 1-10One embodiment of the present invention is: a shell die-casting molding equipment for automobile steering gear production, including a processing table 1, a fixed mold assembly 2 is provided on one side of the top of the processing table 1, a movable mold assembly 3 is provided on the other side of the top of the processing table 1, and a spraying device 4 is fixedly provided at the bottom of the inner wall of the processing table 1.

A screw 43 is fixed to the top of the output end of the motor 42, and the external thread of the screw 43 is connected to a U-shaped push plate 45, and the U-shaped push plate 45 is slidably installed on the outside of the middle support rod of the mountain-shaped rod 44. The U-shaped push plate An H-shaped frame 46 is fixed on the top of 45, and atomizing nozzle tubes 47 are rotatably installed on both sides of the H-shaped frame 46. Several brushes 48 are evenly fixed on the outer circumference of the atomizing nozzle tube 47. A through hole for the H-shaped frame 46 to pass through is opened on the top of the processing table 1. The molds corresponding to the fixed mold assembly 2 and the movable mold assembly 3 are located on the movement track of the brush 48. A spraying assembly 41 for injecting a release agent into the atomizing nozzle tube 47 is provided at the bottom of the inner wall of the processing table 1. The spraying assembly 41 includes a release agent box 401, which is fixed to the bottom of the inner wall of the processing table 1. A pump 402 is fixed on the top of the release agent box 401, and a folding tube 403 is fixed on the top of the pump 402. A guide tube 404 is fixed to one end of the stacked pipe 403 away from the pump 402, and the guide tube 404 is fixed to the front side of the H-shaped frame 46. The guide tube 404 is rotatably connected to the front sides of the two atomizing nozzle tubes 47. The interiors of the two atomizing nozzle tubes 47 are communicated with the interiors of the guide tube 404. A driving assembly for driving the atomizing nozzle tube 47 to rotate is provided on the rear side of the atomizing nozzle tube 47. The driving assembly includes a motor 2 49, a pulley 1 410, and two pulley 2 411. The motor 2 49 is fixed to the rear outer wall of the U-shaped push plate 45, the pulley 1 410 is fixed to the rear output end of the motor 2 49, and the two pulleys 2 411 are respectively fixed to the rear sides of the two atomizing nozzle tubes 47. 10 is connected to the two pulleys 411 by belt drive. Through the arrangement of the above structure, the atomizing nozzle tube 47 will spray out the release agent in atomized form while rotating, thereby ensuring that the release agent is evenly covered on the mold surface of the fixed mold assembly 2 and the movable mold assembly 3. At the same time, the brush 48 will brush the mold surface of the fixed mold assembly 2 and the movable mold assembly 3. The brush 48 can remove metal impurities on the mold surface and ensure that the mold surface is clean and flat, which helps to improve the quality of the product. In addition, the brushing of the brush 48 helps to evenly distribute the release agent and ensure that each part of the mold is fully coated, thereby avoiding incomplete demolding due to lack of release agent in certain areas.

[0017] The H-shaped frame 46 is provided with a guide device 5, which includes two elastic arc plates 51, and the two elastic arc plates 51 are respectively fixed on both sides of the inner wall of the H-shaped frame 46. Through the arrangement of the above structure, the elastic arc plates 51 guide the atomized release agent sprayed from the atomizing nozzle tube 47 toward the mold direction of the fixed mold assembly 2 and the movable mold assembly 3, thereby ensuring that the atomized spray of the release agent is accurately sprayed toward the mold surface, avoiding the diffusion and waste of the release agent, thereby helping the release agent to be concentrated and evenly covered on the mold surface, thereby enhancing the demoulding effect. The inner walls of the two elastic arc plates 51 are both laterally slidably installed with arc-shaped slides 53, and a number of arc strips 54 are evenly and equidistantly fixed on the side of the two arc slides 53 away from the elastic arc plates 51. A strip groove is opened in the middle of the two elastic arc plates 51, and two L-shaped push rods are laterally slidably installed inside the strip groove of the elastic arc plate 51. 52, and the L-shaped push rod 52 is slidably connected to the outer wall of the arc slide 53, a spring is provided between the L-shaped push rod 52 and the outer wall of the elastic arc plate 51, a spring is provided between the arc slide 53 and the outer wall of the L-shaped push rod 52, the bottom of the L-shaped push rod 52 is away from the elastic arc plate 51 and is set in a semi-arc shape, and a number of arc blocks are evenly and equidistantly fixed on the outer walls of the two side support rods of the mountain-shaped rod 44, and the arc blocks of the mountain-shaped rod 44 are located on the semi-arc motion trajectory of the L-shaped push rod 52. Through the setting of the above structure, the L-shaped push rod 52 pushes the arc slide 53 and the arc bar 54 toward the brush 48, so that the arc slide 53 and the arc bar 54 squeeze and scatter the brush 48. The scattering of the brush 48 helps to more effectively make the contact surface between the release agent and the mold during the process of applying the release agent. This effect can improve the distribution efficiency of the release agent and ensure that every part of the mold is properly coated with the release agent.

[0018] The front sides of the two front curved bars 54 are fixed with interference rods 56, and both sides of the front top of the H-shaped frame 46 are fixed with protrusion plates 55. The rear sides of the protrusion plates 55 are evenly and equidistantly fixed with a number of semi-arc protrusions. The front side of the interference rod 56 is semicircular, and the semi-arc protrusions of the protrusion plate 55 are located on the semicircular movement trajectory of the interference rod 56. Through the setting of the above structure, the interference rod 56 pushes the front curved bar 54 to move laterally, and the front curved bar 54 drives the curved slide plate 53 to displace along the outside of the L-shaped push rod 52, and the curved slide plate 53 drives the curved bar 54 to displace, so that the curved slide plate 53 and the curved bar 54 are moved in the horizontal direction while approaching the brush 48, so that the curved bar 54 can further squeeze and scatter the brush 48.

[0019] During use, after the automobile steering gear is formed between the fixed mold assembly 2 and the movable mold assembly 3, the mold of the movable mold assembly 3 moves and separates from the mold of the fixed mold assembly 2. The external manipulator will then take out the automobile steering gear formed on the mold. Then, the staff starts the motor 1 42 and the motor 2 49. The motor 2 49 drives the pulley 1 410 to rotate. The pulley 1 410 drives the two pulley 2 411 to rotate through the belt. The two pulley 2 411 drives the two atomizing nozzle tubes 47 to rotate. The two atomizing nozzle tubes 47 drive the brushes 48 to rotate. At the same time, the motor 1 42 drives the screw 43 to rotate. The screw 43 drives the U-shaped push plate 45 to move upward along the outside of the mountain-shaped rod 44. The U-shaped push plate 45 pushes the H-shaped frame 46 to drive the two atomizing nozzle tubes 47 to move upward. During this process, the staff starts the pump 402, and the pump 402 extracts the release agent in the release agent box 401 and transmits it to the atomizing nozzle tube 47 through the folding tube 403 and the guide tube 404, so that the atomizing nozzle tube 47 can spray out the release agent in atomization while rotating, thereby ensuring that the release agent is evenly covered on the mold surface of the fixed mold assembly 2 and the movable mold assembly 3, and at the same time the brush 48 will brush the mold surface of the fixed mold assembly 2 and the movable mold assembly 3. The brush 48 can remove metal impurities on the mold surface and ensure that the mold surface is clean and flat, which helps to improve the quality of the product, and the brushing of the brush 48 helps to evenly distribute the release agent, ensuring that every part of the mold is fully coated, avoiding incomplete demolding due to lack of release agent in certain areas.

[0020] It should be noted that when the next automobile steering gear needs to be die-cast, the staff drives the motor 42 to rotate in the opposite direction, the motor 42 drives the screw 43 to rotate in the opposite direction, the screw 43 drives the U-shaped push plate 45 to move downward along the outside of the mountain-shaped rod 44, and the U-shaped push plate 45 pushes the H-shaped frame 46 to drive the two atomizing nozzle tubes 47 to move downward, and during this process, the staff turns off the pump 402.

[0021] When the mold release agent is sprayed out of the atomizing nozzle tube 47, the elastic arc plate 51 will guide the mold release agent sprayed out of the atomizing nozzle tube 47 toward the mold direction of the fixed mold assembly 2 and the movable mold assembly 3, thereby ensuring that the atomized spray of the mold release agent is accurately sprayed toward the mold surface, avoiding diffusion and waste of the mold release agent, thereby helping the mold release agent to be concentratedly and evenly covered on the mold surface, thereby enhancing the demoulding effect; at the same time, when the H-shaped frame 46 moves upward, the H-shaped frame 46 drives the L-shaped push rod 52 to move upward through the elastic arc plate 51, and when the semi-arc shape of the L-shaped push rod 52 moves to the arc block position of the mountain-shaped rod 44, the arc block of the mountain-shaped rod 44 pushes the semi-arc shape of the L-shaped push rod 52 to drive the L-shaped push rod 52 to move in the direction of the elastic arc plate 51, and the spring corresponding to the L-shaped push rod 52 is compressed, and the L-shaped push rod 52 pushes the arc slide 53 and the arc bar 54 toward the brush 48, so that the arc slide 53 and the arc bar 54 squeeze the brush 48 and scatter it, The scattering of the brush 48 helps to more effectively spread the release agent to the contact surface of the mold during the application of the release agent. This effect can improve the distribution efficiency of the release agent and ensure that every part of the mold is properly coated with the release agent. At the same time, when the L-shaped push rod 52 pushes the arc-shaped slide 53 and the arc-shaped bar 54 toward the brush 48, the arc-shaped slide 53 drives the resistance rod 56 to move with it. When the semicircular shape of the resistance rod 56 moves to the semi-arc convex position of the convex plate 55, the semi-arc convex of the convex plate 55 The semicircular shape of the push rod 56 drives the push rod 56 to move, and the arc bar 54 on the front side of the push rod 56 moves laterally. The arc bar 54 on the front side pushes the arc slide 53 to move along the outside of the L-shaped push rod 52, and the arc slide 53 drives the arc bar 54 to move, so that the arc slide 53 and the arc bar 54 are moved toward the brush 48 while also moving in the horizontal direction, so that the arc bar 54 can further squeeze and scatter the brush 48.

[0022] See also Figures 1-10On the basis of the above embodiment, in another embodiment of the present application, the top of the H-shaped frame 46 is provided with a residual prevention device 6, which comprises two triangular plates 65, two bidirectional elastic telescopic rods 61 fixed respectively at the top front side and the top rear side of the H-shaped frame 46, and two T-shaped rods 62 fixed respectively at the two sides of the two bidirectional elastic telescopic rods 61. One side of the two T-shaped rods 62 is fixed with a push column one 63 away from the center of the H-shaped frame 46, and the other side of the two T-shaped rods 62 is fixed with a push column two 64 close to the center of the H-shaped frame 46. The two triangular plates 65 are fixed respectively between the two sides of the two T-shaped rods 44. The push column one 63 is in contact with the outer wall of the elastic arc plate 51, and the push column two 64 is in contact with the inclined surface of the triangular plate 65. When the H-shaped frame 46 moves downward each time, the push column one 63 is bent against the upper outer wall of the elastic arc plate 51 due to the structure described above. As the atomizing nozzle pipe 47 continues to drive the brush 48 to rotate, the rotation of the brush 48 will make the brush 48 hit the bent part of the elastic arc plate 51. The impact force of the hitting will help to loosen and remove the residual desulfurizer on the brush 48, reducing the possibility of the accumulation of the desulfurizer on the brush 48, thereby avoiding the problem that the residual mold release agent on the brush 48 is not cleaned in time, causing the mold release agent to change chemically due to oxidation, pollution, etc., losing its proper lubricating and demolding performance, and affecting the quality of the subsequent die casting process.

[0023] When the H-shaped frame 46 moves upward each time, the H-shaped frame 46 drives the push column two 64 to move upward through the bidirectional elastic telescopic rod 61. At this time, the push column two 64 is separated from the inclined surface of the triangular plate 65. Under the action of the elastic force of the bidirectional elastic telescopic rod 61, the bidirectional elastic telescopic rod 61 pulls the T-shaped rod 62 to drive the push column one 63 to move towards the center of the H-shaped frame 46. The push column one 63 is no longer against the outer wall of the elastic arc plate 51. The elastic arc plate 51 resets under the action of its own elastic force. The elastic arc plate 51 is not on the movement track of the brush 48 at this time. When the H-shaped frame 46 moves downward each time, the H-shaped frame 46 drives the push column two 64 to move downward through the bidirectional elastic telescopic rod 61. At this time, the inclined surface of the triangular plate 65 pushes the push column two 64 to drive the T-shaped rod 62 to move away from the center of the H-shaped frame 46. The push column one 63 re-contacts the outer wall of the elastic arc plate 51, so that the upper outer wall of the elastic arc plate 51 is bent. At this time, the elastic arc plate 51 is on the movement track of the brush 48. Since the bent part of the elastic arc plate 51 will hinder the movement direction of the brush 48, as the atomizing nozzle pipe 47 continues to drive the brush 48 to rotate, the rotation of the brush 48 will make the brush 48 hit the bent part of the elastic arc plate 51. The impact force of the hitting will help to loosen and remove the residual desulfurizer on the brush 48, reducing the possibility of the accumulation of the desulfurizer on the brush 48, thereby avoiding the problem that the residual mold release agent on the brush 48 is not cleaned in time, causing the mold release agent to change chemically due to oxidation, pollution, etc., losing its proper lubricating and demolding performance, and affecting the quality of the subsequent die casting process.

[0024] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
