Description

Technical Field

[0001] The invention relates to the field of moulds, and in particular to a casting mould for producing concrete sleepers. Background Art

[0002] The casting mold used for the production of concrete sleepers, also known as concrete sleeper molds or concrete sleeper molds, is a mold specially used to produce concrete sleepers or concrete sleepers on transportation routes such as railways and highways.

[0003] Most of the existing casting molds are welded from iron plates. Although they are strong, the stress generated by the concrete during solidification is released onto the template. In particular, molds with poor welding quality are more prone to cracking, and it is not convenient to demold after the concrete is solidified. Currently, demolding is done by knocking, which aggravates the damage to the mold. In addition, the use of vibrators during pouring can easily damage the mold.

[0004] For this reason, we use this technical solution to solve the problem that the existing mold is easily damaged. Summary of the invention

[0005] The purpose of the present invention is to improve the casting mold in the prior art. Compared with the prior art, a casting mold for concrete sleeper production is provided. By adding stress absorbing protective parts on the basis of the existing casting mold, the vibrator can be directly placed on the shaping plate during casting. The elasticity of the hollow shaping shell and the vibrator expander can not only effectively increase the vibration area to help the concrete to discharge bubbles, but also play a buffering and protective role on the mold body, avoiding direct contact between the vibrator and the mold. In addition, the back and forth repulsion of the fixed magnetic disk to the moving magnetic disk during vibration can also effectively improve the vibration effect. Due to the adjustable elasticity, it is also convenient for concrete demolding. The elasticity of the hollow shaping shell and the vibrator expander can also effectively absorb the stress released by the concrete during solidification, effectively reducing the damage to the mold by the stress. In addition, the expansion and contraction state of the concrete after solidification is intuitively reflected through the solidification state feedback device, which is convenient for workers to understand and grasp the molding of the concrete.

[0006] Realize the protection of mold and feedback of curing status.

[0007] Furthermore, the hollow molding shell and the molding plate are both made of friction-resistant hard material, and the side wall of the hollow molding shell is fixedly inlaid with multiple elastic connecting strips, and the elastic connecting strips are made of polyurethane elastic material. In order to not affect the plasticity of concrete and its shape after solidification, the hollow molding shell and the molding plate are both made of hard material. The addition of the elastic connecting strips makes the hollow molding shell elastic, so that the entire stress absorbing guard can vibrate to increase the vibration area, and at the same time, it can also achieve effective shock absorption protection for the mold body.

[0008] Furthermore, the solidification status monitoring component includes a deformable liquid capsule that forms a closed space with two moving disks, and the deformable liquid capsule is made of elastic material. The solidification status monitoring component has the characteristics of being able to be compressed and stretched. In this way, after the concrete sleeper is solidified, the deformable characteristics of the solidification status monitoring component can effectively absorb the stress released during the solidification of the sleeper, thereby effectively protecting the mold body.

[0009] Optionally, a protective shell is fixedly connected to the middle part of the upper end of the elastic vibration seat, and the protective shell extends to the top of the hollow plastic shell, both side walls of the protective shell are fixedly inlaid with magnetic inserts, and a transparent observation plate is fixedly connected to the upper opening of the protective shell, the inner wall of the protective shell is slidably connected to a solidification state feedback device matching the magnetic insert, and the protective shell is located below the solidification state feedback device and is also filled with driving liquid, the middle part of the liquid pipe is connected to the bottom of the protective shell through a connecting pipe, and the concrete sleeper's squeezing effect on the plastic plate when expanding and contracting is ultimately transmitted to the solidification state monitoring component, thereby determining whether the solidification state monitoring component is in a compressed or stretched state, and then the driving liquid inside the solidification state monitoring component flows into the protective shell, and the solidification state feedback device floats on the driving liquid surface, and the amount of driving liquid flowing into the protective shell determines at which level of the magnetic insert the solidification state feedback device is, and by observing the reaction of the solidification state feedback device, it can be known that the state of the concrete sleeper after solidification is in the three states of normal solidification, over-expansion, and over-contraction, thereby achieving intuitive feedback on the solidification state of the concrete sleeper.

[0010] Optionally, the magnetic embedded parts include permanent magnetic pad one, permanent magnetic pad two and permanent magnetic pad three arranged from bottom to top, and the magnetic forces of permanent magnetic pad one, permanent magnetic pad two and permanent magnetic pad three increase successively, and the magnetic repulsion forces of permanent magnetic pad one, permanent magnetic pad two and permanent magnetic pad three on the solidification status feedback device increase successively, so that the responses of the solidification status feedback device are different, so that the specific solidification status of the concrete sleeper can be intuitively fed back, which is convenient for the staff to grasp the situation in time.

[0011] Optionally, the solidification state feedback device includes a floating seat, and the side walls at both ends of the floating seat facing the magnetic embedded part are provided with sliding grooves, and a magnetic slider that magnetically repels the magnetic embedded part is slidably connected in the sliding groove, and a spring is fixedly connected between the magnetic slider and the inner wall of the sliding groove, and the side walls on both sides of the middle part of the floating seat are provided with L-shaped open sliding grooves with openings facing upward, and a feedback belt is slidably connected in the L-shaped open sliding groove, and the side walls of the magnetic slider are fixedly connected with a connecting rod, and the connecting rod passes through the L-shaped open sliding groove and is fixedly connected to the feedback belt, and the permanent magnetic pads 1, 2 and 3 have a pair of magnetic sliders. A magnetic repulsion force is generated, and the magnitude of the magnetic repulsion forces is different between each other. When the magnetic slider is subjected to the magnetic repulsion force, it drives the feedback belt to move. The state of the sleeper can be known by observing the exposed length of the feedback belt through the transparent observation plate. When the sleeper is in an over-contracted state, the magnetic slider is on the first layer of the permanent magnetic pad, and the exposed length of the feedback belt is one-third. When the sleeper is in a normal state, the magnetic slider is on the second layer of the permanent magnetic pad, and the exposed length of the feedback belt is two-thirds. When the sleeper is in an over-expanded state, the magnetic slider is on the third layer of the permanent magnetic pad, and the feedback belt is completely exposed.

[0012] Optionally, the feedback belt is composed of three reflective films of the same size, and the colors of the three reflective films are different. The three reflective films each occupy one-third of the total length of the feedback belt. With the different colors, it is convenient for workers to check the exposed length of the feedback belt, thereby accurately judging the curing state of the sleeper.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) This scheme adds stress-absorbing protective parts to the existing casting mold. During casting, the vibrator can be placed directly on the shaping plate. The elasticity of the hollow shaping shell and the vibrator expander can not only effectively increase the vibration area to help the concrete to expel bubbles, but also play a buffering and protective role on the mold body, avoiding direct contact between the vibrator and the mold. In addition, the back-and-forth repulsion of the fixed magnetic disk to the moving magnetic disk during vibration can effectively improve the vibration effect. Due to the adjustable elasticity, it is also convenient for concrete demoulding. The elasticity of the hollow shaping shell and the vibrator expander can also effectively absorb the stress released by the concrete during solidification, effectively reducing the damage to the mold caused by stress. In addition, the expansion and contraction state of the concrete after solidification is intuitively reflected through the solidification state feedback device, which is convenient for workers to understand and grasp the forming of the concrete, and realize the protection of the mold and the feedback of the solidification state.

[0015] (2) Both the hollow molding shell and the molding plate are made of friction-resistant hard material. The side wall of the hollow molding shell is fixedly inlaid with multiple elastic connecting strips, and the elastic connecting strips are made of polyurethane elastic material. In order to prevent the plasticity of concrete from affecting its shape after solidification, the hollow molding shell and the molding plate are both made of hard material. The addition of the elastic connecting strips makes the hollow molding shell elastic, so that the entire stress absorbing guard can vibrate to increase the vibration area, and at the same time, it can also achieve effective shock absorption protection for the mold body.

[0016] (3) The solidification status monitoring component includes a deformable liquid bag that forms a closed space with two moving disks, and the deformable liquid bag is made of elastic material. The solidification status monitoring component has the characteristics of being able to be compressed and stretched. In this way, after the concrete sleeper is solidified, the deformable characteristics of the solidification status monitoring component can effectively absorb the stress released during the solidification of the sleeper, thereby effectively protecting the mold body.

[0017] (4) A protective shell is fixedly connected to the middle of the upper end of the elastic vibration seat, and the protective shell extends to the top of the hollow plastic shell. Both side walls of the protective shell are fixedly inlaid with magnetic inserts, and a transparent observation plate is fixedly connected to the upper opening of the protective shell. The inner wall of the protective shell is slidably connected to a solidification state feedback device matching the magnetic insert, and the protective shell is located below the solidification state feedback device and is also filled with driving liquid. The middle part of the liquid pipe is connected to the bottom of the protective shell through a connecting pipe. When the concrete sleeper expands and contracts, its squeezing effect on the plastic plate is finally transmitted to the solidification state monitoring device, thereby determining whether the solidification state monitoring device is in a compressed or stretched state. Then, the driving liquid inside the solidification state monitoring device flows into the protective shell, and the solidification state feedback device floats on the liquid surface of the driving liquid. The amount of driving liquid flowing into the protective shell determines at which level of the magnetic insert the solidification state feedback device is located. By observing the reaction of the solidification state feedback device, it can be known whether the state of the concrete sleeper after solidification is in the three states of normal solidification, over-expansion, and over-contraction, thereby realizing intuitive feedback on the solidification state of the concrete sleeper.

[0018] (5) The magnetic embedded parts include permanent magnetic pad 1, permanent magnetic pad 2 and permanent magnetic pad 3 arranged from bottom to top, and the magnetic forces of permanent magnetic pad 1, permanent magnetic pad 2 and permanent magnetic pad 3 increase successively, and the magnetic repulsion forces of permanent magnetic pad 1, permanent magnetic pad 2 and permanent magnetic pad 3 on the solidification state feedback device increase successively, so that the responses of the solidification state feedback device are different, so that the specific solidification state of the concrete sleeper can be intuitively fed back, which is convenient for the staff to grasp the situation in time.

[0019] (6) The solidification state feedback device includes a floating seat, and the side walls of the floating seat at both ends facing the magnetic embedded part are provided with a slide groove, and a magnetic slider that repel the magnetic embedded part is slidably connected in the slide groove, and a spring is fixedly connected between the magnetic slider and the inner wall of the slide groove, and the side walls of the middle part of the floating seat are provided with an L-shaped open slide groove with an opening facing upward, and a feedback belt is slidably connected in the L-shaped open slide groove, and the side wall of the magnetic slider is fixedly connected with a connecting rod, and the connecting rod passes through the L-shaped open slide groove and is fixedly connected to the feedback belt, and the permanent magnetic pads 1, 2 and 3 are all generated on the magnetic sliders. The magnetic repulsion force is different in size. When the magnetic slider is subjected to the magnetic repulsion force, it drives the feedback belt to move. The state of the sleeper can be known by observing the exposed length of the feedback belt through the transparent observation plate. When the sleeper is in an over-contracted state, the magnetic slider is on the first layer of the permanent magnetic pad, and the exposed length of the feedback belt is one-third. When the sleeper is in a normal state, the magnetic slider is on the second layer of the permanent magnetic pad, and the exposed length of the feedback belt is two-thirds. When the sleeper is in an over-expanded state, the magnetic slider is on the third layer of the permanent magnetic pad, and the feedback belt is completely exposed.

[0020] (7) The feedback belt is composed of three reflective films of the same size, and the colors of the three reflective films are different. The three reflective films each occupy one-third of the total length of the feedback belt. The different colors make it convenient for workers to check the exposed length of the feedback belt, so as to accurately judge the curing status of the sleeper. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figure 3 , 4 and Figure 6A vibrator 5 is fixedly connected to the inside of the hollow shaping shell 3, and the vibrator 5 is also fixedly connected to the shaping plate 4. The vibrator 5 includes an elastic vibration seat 6 in the middle, and hard vibration transmission layers 7 are fixedly connected to both sides of the elastic vibration seat 6. The inner walls on both sides of the elastic vibration seat 6 are provided with mounting holes 601, and the hard vibration transmission layer 7 is fixedly inlaid with a fixed magnetic disk 8 on the side wall facing the mounting hole 601. Two symmetrically distributed moving magnetic disks 9 are slidably connected in the mounting hole 601, and the two moving magnetic disks 9 are magnetically repelled from the two fixed magnetic disks 8 respectively. A solidification state monitoring component 10 is fixedly connected between the two moving magnetic disks 9. The solidification state monitoring component 1 0 includes a deformable liquid capsule that forms a closed space with two moving disks 9, and the deformable liquid capsule is made of elastic material (rubber material is preferably selected, and other materials can also be selected according to actual needs), and the solidification state monitoring component 10 has the characteristics of being able to be compressed and stretched. In this way, after the concrete sleeper is solidified, the deformable characteristics of the solidification state monitoring component 10 can effectively absorb the stress released when the sleeper is solidified, thereby effectively protecting the mold body 1. The interior of the solidification state monitoring component 10 is filled with driving liquid (hydraulic oil is preferably selected, and other liquids can also be selected according to actual needs), and a liquid pipe 11 is connected between the two solidification state monitoring components 10.

[0036] Based on Example 1, please refer to Figure 7 , 8 , a protective shell 12 is fixedly connected to the middle part of the upper end of the elastic vibration seat 6, and the protective shell 12 penetrates to the top of the hollow plastic shell 3, and the side walls of the protective shell 12 are fixedly inlaid with magnetic embedded parts 13, and the magnetic embedded parts 13 include a permanent magnetic pad 1 1301, a permanent magnetic pad 2 1302 and a permanent magnetic pad 3 1303 arranged from bottom to top, and the magnetic forces of the permanent magnetic pad 1 1301, the permanent magnetic pad 2 1302 and the permanent magnetic pad 3 1303 increase successively, and the magnetic repulsion forces of the permanent magnetic pad 1 1301, the permanent magnetic pad 2 1302 and the permanent magnetic pad 3 1303 on the solidification state feedback device 15 increase successively, so that the response of the solidification state feedback device 15 is different, so that the specific solidification state of the concrete sleeper can be intuitively fed back, which is convenient for the staff to grasp the situation in time;

[0037] See also Figure 7, and a transparent observation plate 14 is fixedly connected to the upper opening of the protective shell 12, and a solidification state feedback device 15 matching the magnetic insert 13 is slidably connected to the inner wall of the protective shell 12, and the protective shell 12 is located below the solidification state feedback device 15 and is also filled with a driving liquid. The middle part of the liquid pipe 11 is connected to the bottom of the protective shell 12 through a connecting pipe. When the concrete sleeper expands and contracts, its squeezing effect on the shaping plate 4 is finally transmitted to the solidification state monitoring component 10, thereby determining whether the solidification state monitoring component 10 is in a compressed or stretched state, and then the driving liquid inside the solidification state monitoring component 10 flows into the protective shell 12, and the solidification state feedback device 15 floats on the driving liquid surface. The amount of driving liquid flowing into the protective shell 12 determines the horizontal plane of the magnetic insert 13 on which the solidification state feedback device 15 is located. By observing the reaction of the solidification state feedback device 15, it can be known that the state of the concrete sleeper after solidification is in the three states of normal solidification, over-expansion, and over-contraction, thereby realizing intuitive feedback on the solidification state of the concrete sleeper;

[0038] See also Figure 8 , 9 and Fig.10The solidification state feedback device 15 includes a floating seat 1501. The side walls of both ends of the floating seat 1501 facing the magnetic embedded part 13 are provided with a slide groove 1502, and a magnetic slider 1503 that magnetically repels the magnetic embedded part 13 is slidably connected in the slide groove 1502. A spring is fixedly connected between the magnetic slider 1503 and the inner wall of the slide groove 1502. The side walls on both sides of the middle part of the floating seat 1501 are provided with an L-shaped open slide groove 1504 with an opening facing upward, and a feedback belt 1505 is slidably connected in the L-shaped open slide groove 1504. The feedback belt 1505 is composed of three reflective films of the same size, and the colors of the three reflective films are different from each other. The three reflective films each occupy one-third of the total length of the feedback belt 1505. With the different colors, it is convenient for workers to check the exposed length of the feedback belt 1505, so as to accurately judge the solidification state of the sleeper. The side wall of the magnetic slider 1503 is fixedly connected with a connecting rod, and the connecting rod It penetrates into the L-shaped open slide groove 1504 and is fixedly connected to the feedback belt 1505. The permanent magnetic pad 1 1301, the permanent magnetic pad 2 1302 and the permanent magnetic pad 3 1303 all generate magnetic repulsion force on the magnetic slider 1503, and the magnitude of the magnetic repulsion force between each is different. After being subjected to the magnetic repulsion force, the magnetic slider 1503 drives the feedback belt 1505 to move. The state of the sleeper can be known by observing the exposed length of the feedback belt 1505 through the transparent observation plate 14. When the sleeper is in an over-contracted state, the magnetic slider 1503 is in the permanent magnetic pad 1 1301 layer, and the exposed length of the feedback belt 1505 is one-third. When the sleeper is in a normal state, the magnetic slider 1503 is in the permanent magnetic pad 2 1302 layer, and the exposed length of the feedback belt 1505 is two-thirds. When the sleeper is in an over-expanded state, the magnetic slider 1503 is in the permanent magnetic pad 3 1303 layer, and the feedback belt 1505 is completely exposed.

[0039] The working principle of this solution is as follows: when pouring concrete into the mold body 1, vibrator is used to vibrate. The vibrator can be placed directly on the stress absorbing protective member 2. Under the vibration of the vibrator, the vibration of the shaping plate 4 is transmitted to the vibrating expander 5. The mutual magnetic repulsion between the fixed magnetic disk 8 and the moving magnetic disk 9 causes the entire hard shock-transmitting layer 7 to vibrate, thereby effectively expanding the vibration area of ​​the vibrator, helping the concrete to quickly expel internal bubbles, and effectively speeding up the pouring efficiency. At the same time, the vibrating expander 5 and the solidification state monitoring member 10 can also absorb the vibration and the stress released when the concrete is solidified, thereby effectively protecting the mold body 1. When the concrete is solidified, the extrusion force of the concrete sleeper on the shaping plate 4 is transmitted to the solidification state monitoring member 10, and the driving liquid inside the solidification state monitoring member 10 is squeezed into the bottom of the protective shell 12 through the liquid pipe 11, so that the solidification state The feedback device 15 floats on the liquid surface, and the permanent magnetic pad 1 1301, the permanent magnetic pad 2 1302 and the permanent magnetic pad 3 1303 all generate magnetic repulsion forces on the magnetic slider 1503, and the magnitudes of the magnetic repulsion forces between each are different. After being subjected to the magnetic repulsion force, the magnetic slider 1503 drives the feedback belt 1505 to move. The state of the sleeper can be known by observing the exposed length of the feedback belt 1505 through the transparent observation plate 14. When the sleeper is in an over-contracted state, the magnetic slider 1503 is in the permanent magnetic pad 1 1301 layer, and the exposed length of the feedback belt 1505 is one-third. When the sleeper is in a normal state, the magnetic slider 1503 is in the permanent magnetic pad 2 1302 layer, and the exposed length of the feedback belt 1505 is two-thirds. When the sleeper is in an over-expanded state, the magnetic slider 1503 is in the permanent magnetic pad 3 1303 layer, and the feedback belt 1505 is completely exposed.
