[0018] 1. The demoulding device for tunnel lining described in the present invention has a demoulding assembly, which can rotate the motor to rotate the mold downward during demoulding, and separate the outer mold from the inner mold under the action of the electric telescopic rod.

[0019] 2. The tunnel lining demoulding device described in the present invention cooperates with structures such as rubber blocks and special-shaped blocks. After the injection is completed, when the inner mold rotates, the rubber blocks will knock the inner mold under the action of the special-shaped blocks, causing the inner mold to vibrate. The vibration can improve the density of the concrete and reduce internal defects.

[0020] 3. In the demoulding device for tunnel lining described in the present invention, when the demoulding work is carried out, the lining will fall on the top of two material receiving seats. After the material receiving seats are subjected to the pressure of the lining, the elastic part B will shrink. Under the action of the elastic part B, the impact force generated when the lining falls will be buffered, thereby playing a role in protecting the lining. The shrinkage of the elastic part B provides conditions for the detachment of the lining. After the lining falls completely on the material receiving seats, the lining can be transported under the action of the conveyor belt, thereby improving the convenience of the device when used.

[0021] 4. The tunnel lining demoulding device described in the present invention, through the cooperation of structures such as rubber strips and strip grooves, when the mold rotates, the rubber strips will reciprocately knock on the outer mold, thereby causing the outer mold to vibrate. When the material is injected into the mold, the density of the material can be further improved through vibration, and the strength and durability of the lining can be enhanced. After the lining is formed, the adhesion between the lining and the outer mold can be eliminated through vibration, thereby preventing the lining from being damaged due to the rotation of the outer mold during demoulding, thereby improving the demoulding effect of the device.

[0022] 5. The tunnel lining demoulding device described in the present invention can drive the mold to rotate when the device is working through the cooperation of the rotating motor and the driving shaft and other structures. The rotation of the mold can adjust the position of the mold. The automatic demoulding of the device can be achieved by rotating the mold downward, so that the lining is automatically separated from the mold, and the demoulding work is more convenient. At the same time, the rotation of the mold is used to make the mold vibrate when it is knocked, thereby improving the quality of lining production and achieving better demoulding effect.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 6As shown, a tunnel lining demoulding device described in an embodiment of the present invention includes side panels 1, the number of side panels 1 is two and they are symmetrically arranged, and also includes a demoulding component, the demoulding component includes two electric telescopic rods 3 and two inner molds 4, the outer walls of the two inner molds 4 are provided with outer molds 5, the demoulding component pushes the outer mold 5 to move by extending the electric telescopic rod 3, so that the outer mold 5 is separated from the inner mold 4, so that the formed lining is separated from the outer mold 5 and the inner mold 4, and then the demoulding work is completed, a driving shaft 2 is rotatably installed between the two side panels 1, a rotating motor 6 is fixedly installed on one side of one side panel 1, and the output end of the rotating motor 6 is fixedly connected to one end of the driving shaft 2; when working, the material for making the lining is injected between the inner mold 4 and the outer mold 5, and when the injected material is solidified and formed, the demoulding work is started. When demoulding, the driving shaft 2 is driven to rotate by the rotating motor 6, and the driving shaft 2 The mold is rotated under the action of the motor 6. When the mold to be demoulded is rotated to the bottom, the electric telescopic rod 3 is started to extend. Under the action of the electric telescopic rod 3, the outer mold 5 located below is pushed to rotate around the driving shaft 2. The outer mold 5 is separated from the inner mold 4 by the rotation of the outer mold 5. Since the outer mold 5 and the inner mold 4 are located below the driving shaft 2, when the outer mold 5 is separated from the inner mold 4, the open part of the inner mold 4 faces downward, and the lining located on the inner side of the inner mold 4 will fall off under the action of gravity, thereby achieving the effect of automatic demoulding. The inner mold 4 and the outer mold 5 can be driven to rotate by the rotating motor 6, and then the position of the mold can be adjusted. When the mold is rotated to the bottom, it is convenient to perform demoulding work, providing conditions for the lining to automatically separate from the mold. At the same time, the mold can be vibrated by rotating the mold, thereby improving the quality of lining production and achieving better demoulding effect.

[0037] like Figures 1 to 6 As shown, two groups of connecting plates 7 are fixedly installed on the outer wall of the driving shaft 2, and the two groups of connecting plates 7 are fixedly connected to the two inner molds 4 respectively. The outer wall of one connecting plate 7 in each group is fixedly connected to one end of the two electric telescopic rods 3 respectively, and the other ends of the two electric telescopic rods 3 are fixedly installed with push-pull blocks 8, and the outer walls of the two push-pull blocks 8 are fixedly connected to the outer walls of the two outer molds 5 respectively; when the demoulding work is performed, the rotating motor 6 drives the driving shaft 2 to rotate, and the driving shaft 2 drives the inner mold 4 and the outer mold 5 to rotate through the connecting plate 7, so that the inner mold 4 and the outer mold 5 that need to be demoulded rotate to the bottom, and the electric telescopic rod 3 is started. The electric telescopic rod 3 extends and pushes the outer mold 5 at the bottom to move through the push-pull block 8. The outer mold 5 rotates with the driving shaft 2 as the center. When the outer mold 5 rotates, the opening of the inner mold 4 will gradually open. When the opening of the inner mold 4 is completely opened, the lining in the inner mold 4 will fall off under the action of gravity, realizing automatic demoulding of the device.

[0038] like Figures 1 to 9 As shown, the outer walls of the two side panels 1 are fixedly installed with receiving blocks 9, one side of the receiving block 9 is fixedly installed with a positioning block 10, the outer wall of the positioning block 10 is fixedly installed with a reset telescopic rod 11, the end of the reset telescopic rod 11 away from the positioning block 10 is fixedly installed with a moving block 12, between the moving block 12 and the positioning block 10 and located on the outside of the reset telescopic rod 11 is fixedly installed with an elastic member A13, the side of the moving block 12 away from the reset telescopic rod 11 is fixedly installed with a rubber block 14, and the inner side of the inner mold 4 is symmetrically and evenly fixedly installed with a plurality of special-shaped blocks 15; after the material is injected between the inner mold 4 and the outer mold 5, the rotating motor 6 drives the mold to rotate, and during the rotation of the mold, the special-shaped blocks 15 connected to the inner mold 4 will alternately conflict with the rubber blocks 14. When the rubber block 14 collides with the special-shaped block 15, the rubber block 14 will be squeezed by the special-shaped block 15 to cause the elastic part A13 to contract. Each time the rubber block 14 passes over the special-shaped block 15, the elastic part A13 will reset under the action of its own elastic force to cause the rubber block 14 to hit the inner mold 4. The inner mold 4 will vibrate after being hit. The vibration can make the material in the mold be better mixed, thereby improving the density of the material and further improving the production quality of the lining. When the material is fixed and formed, the rotating motor 6 will drive the mold to rotate again, thereby causing the rubber block 14 to hit the inner mold 4 again. The rubber block 14 knocks on the inner mold 4, so that the adhesion between the formed lining and the inner mold 4 disappears, thereby better performing the demoulding work.

[0039] like Figures 1 to 9 As shown, a conveyor belt 16 is arranged between the two side plates 1, and a plurality of bottom plates 17 are fixedly mounted on the outer wall of the conveyor belt 16, and a group of supporting telescopic rods 18 are fixedly mounted on the outer wall of each bottom plate 17, and a support frame 19 is fixedly mounted between each group of supporting telescopic rods 18, and an elastic member B20 is fixedly mounted between the support frame 19 and the bottom plate 17 and on the outer side of each supporting telescopic rod 18, and a material receiving seat 21 is fixedly mounted on the top of the support frame 19, and one of the outer molds 5 is located between the tops of two of the material receiving seats 21; when demolding is performed, the lining will fall between the two material receiving seats 21, and the elastic member B20 will shrink when the lining falls, thereby buffering the impact force generated when the lining falls, and protecting the lining during demolding, and at the same time, due to the shrinkage of the elastic member B20, the lining can be separated from the inner mold 4, and then the lining can be transported under the action of the conveyor belt 16, thereby improving the convenience of using the device.

[0040] like Figures 1 to 10As shown, a sliding stop 34 is slidably installed on the inner wall of the material receiving seat 21, and an elastic member C35 is fixedly installed between the outer wall of the sliding stop 34 and the inner wall of the material receiving seat 21, and a rubber strip 36 is fixedly installed on the outer wall of the sliding stop 34 away from the elastic member C35. A plurality of strip grooves 37 are evenly opened on the outer wall of the outer mold 5, and the inner walls of two of the strip grooves 37 are slidably connected with the outer walls of two of the rubber strips 36; when the rotating motor 6 drives the mold to rotate, as the mold rotates, the outer mold 5 will circulate through the two corresponding material receiving seats 21 below, and when the outer mold 5 passes through the material receiving seat 21, the outer mold 5 will squeeze the rubber strip 36 in the material receiving seat 21, and the rubber strip 36 will shrink to the inner side of the material receiving seat 21 after being squeezed, and then The sliding stop 34 squeezes and contracts the elastic part C35. When the strip groove 37 on the outer mold 5 is aligned with the rubber strip 36, the rubber strip 36 suddenly loses the squeezing force of the outer mold 5, which causes the elastic part C35 to reset and stretch. Under the action of the elastic force of the elastic part C35, the rubber strip 36 pops out and hits the outer mold 5. Since there are multiple strip grooves 37, the rubber strip 36 will repeatedly hit the outer mold 5. When the material is injected into the mold, the knocking of the rubber strip 36 further improves the density of the material, and improves the strength and durability of the lining. Before the demolding work is carried out, the rubber strip 36 knocks to eliminate the adhesion between the lining and the outer mold 5, thereby avoiding the workpiece from being strained when the outer mold 5 rotates, thereby improving the demolding effect of the device.

[0041] like Figures 1 to 8 As shown, a conveying roller 22 is symmetrically installed on the inner side of the conveyor belt 16, and a conveying shaft 23 is fixedly installed on the inner walls of the two conveying rollers 22. A conveying motor 24 is arranged on one side of the conveying belt 16, and the output end of the conveying motor 24 is fixedly connected to one end of one of the conveying shafts 23, and both ends of the two conveying shafts 23 are rotatably installed with an outer frame 25, and the conveying motor 24 is fixedly installed on one side of one of the outer frames 25, and a base 26 is fixedly installed between the bottoms of the outer frames 25, and two vertical plates 27 are fixedly installed on the top of the base 26, and the tops of the two vertical plates 27 are respectively fixedly connected to the bottoms of the two side plates 1; the conveying motor 24 drives the conveying shaft 23 to rotate, and the conveying shaft 23 drives the conveying rollers 22 to rotate, and the conveying belt 16 is operated under the action of the conveying rollers 22, and the conveying belt 16 will drive the receiving seat 21 to move through the bottom plate 17 and other structures during operation, and the lining located on the receiving seat 21 will move with it, thereby achieving the effect of conveying the lining.

[0042] like Figures 1 to 4As shown, a group of arc-shaped limit plates 28 are fixedly installed on the outer walls of the two push-pull blocks 8, and the outer walls of the two groups of arc-shaped limit plates 28 are respectively slidably connected with the inner walls of the two groups of connecting plates 7, and an injection tube 29 is fixedly installed on the inner wall of the inner mold 4, and a sealing valve 30 is threadedly installed on the inner wall of the injection tube 29; the push-pull blocks 8 are limited by the set arc-shaped limit plates 28, and then the outer mold 5 is limited, so that the outer mold 5 remains stable when moving along the preset direction, and the outer mold 5 is prevented from shifting. When the mold is rotated to one side, the injection tube 29 is located above the mold, and the sealing valve 30 is opened to make the injection tube 29 in a smooth state, and the material for lining production is injected into between the inner mold 4 and the outer mold 5 through the injection tube 29, and the lining molding work is realized through the cooperation of the inner mold 4 and the outer mold 5.

[0043] like Figure 1 to Figure 2 As shown, one side of one of the side panels 1 and the outer frame 25 is fixedly installed with a mounting seat 31, the rotating motor 6 and the conveying motor 24 are respectively fixedly installed on the inner sides of the two mounting seats 31, the top of the base 26 is fixedly installed with a supporting leg 32, the top of the supporting leg 32 is fixedly installed with a control box 33, and the inner wall of the top of the control box 33 is fixedly installed with a display screen and control buttons; the rotating motor 6 and the conveying motor 24 are respectively fixed by the two mounting seats 31, so that the rotating motor 6 and the conveying motor 24 can provide stable power for the operation of the device, the device can be controlled to work through the control box 33, the display screen can display the working status of the device, and the control buttons can issue corresponding working instructions to the device.

[0044] Working principle: Start the rotating motor 6 to drive the driving shaft 2 to rotate, and the driving shaft 2 drives the inner mold 4 and the outer mold 5 to rotate simultaneously through the connecting plate 7. When the corresponding inner mold 4 is rotated to one side, the sealing valve 30 is opened, and the material for making the lining is injected into the space between the inner mold 4 and the outer mold 5 through the injection pipe 29. After the material is injected, it is sealed through the sealing valve 30.

[0045] After the mold is sealed, the rotating motor 6 drives the mold to continue rotating. When the inner mold 4 rotates, the special-shaped blocks 15 connected thereto will successively collide with the rubber blocks 14. When the collision occurs, the rubber blocks 14 are squeezed by the special-shaped blocks 15 to cause the elastic part A13 to shrink. When the rubber blocks 14 pass over the special-shaped blocks 15, the rubber blocks 14 will hit the inner mold 4 under the action of the reverse elastic force of the elastic part A13, thereby causing the inner mold 4 to vibrate. The density of the material in the mold is improved by vibration. When the mold is subjected to sufficient vibration, the rotating motor 6 stops working to make the mold still, thereby fixing the internal material into shape.

[0046] After the material in the mold is fixed and formed, the rotating motor 6 drives the mold to rotate again. When the mold rotates, the rubber block 14 will knock the inner mold 4 again to make the inner mold 4 vibrate. Through the vibration of the inner mold 4, the adhesion between the molded material and the inner mold 4 disappears. After the vibration is completed, the mold is distributed vertically up and down under the action of the rotating motor 6, and then the electric telescopic rod 3 located below will extend. The electric telescopic rod 3 pushes the outer mold 5 below to separate from the inner mold 4 through the push-pull block 8. When the outer mold 5 is separated from the inner mold 4, the lining in the inner mold 4 will fall off, and the fallen lining will fall between the two material receiving seats 21. After the material receiving seat 21 is subjected to the pressure of the lining, the elastic part B20 will shrink, thereby causing the lining to drop. Finally, under the action of the conveying motor 24, the conveyor belt 16 is operated to convey the demolded lining.

[0047] When the rotating motor 6 drives the mold to rotate so that the rubber block 14 performs the knocking work, as the mold rotates, the outer mold 5 will cyclically pass over the two corresponding material receiving seats 21 below. When the outer mold 5 passes the material receiving seat 21, the outer mold 5 will conflict with the rubber strip 36 in the material receiving seat 21. After being squeezed, the rubber strip 36 will shrink into the inner side of the material receiving seat 21, thereby shrinking the elastic member C35. When the strip groove 37 on the outer mold 5 is aligned with the rubber strip 36, the rubber strip 36 suddenly loses the outer mold 5. The extrusion pressure will cause the elastic member C35 to reset and stretch, and the rubber strip 36 will pop out and hit the outer mold 5 under the action of the elastic force of the elastic member C35. Since there are multiple strip grooves 37, the rubber strip 36 will repeatedly hit the outer mold 5. When the material is injected into the mold, the knocking of the rubber strip 36 will further improve the density of the material, and the strength and durability of the lining will be improved. When the demolding work is carried out, the knocking of the rubber strip 36 will make the adhesion between the lining and the outer mold 5 disappear, so as to avoid the workpiece from being strained when the outer mold 5 rotates.
