[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] 1-9 , an embodiment of the present invention provides a fully automatic mold for a concrete circular tube, comprising a bottom mold 1, an end mold, an inner mold 2, an outer mold 3 and a frame 4. The bottom mold 1, the end mold, the inner mold 2 and the outer mold 3 are spliced ​​together to form a pouring space for the concrete circular tube. A driving mechanism is provided on the frame 4, which is limitedly connected to the frame 4 and has a first stroke and a second stroke. In the first stroke, the driving mechanism drives the outer mold 3 to approach or move away from the bottom mold 1, and in the second stroke, the driving mechanism drives the outer mold 3 to vibrate.

[0034] Specifically, before pouring the concrete circular pipe culvert, each template needs to be spliced ​​to form a pouring space; the splicing method between each template is the existing technology and will not be described in detail; the fully automatic concrete circular pipe mold provided in the embodiment of the present invention is mainly used for teardrop-shaped concrete circular pipes. The illustrations and descriptions are based on the teardrop-shaped concrete circular pipe. It includes a bottom mold 1 and two outer molds 3 (i.e., side molds). The two outer molds 3 are slidably connected to the corresponding frame 4. A slide rail structure (not shown) can be set between the frame 4 and the outer mold 3. When pouring is required, the outer mold 3 is moved along the slide rail close to the bottom mold 1 to splice the bottom mold 1 and the outer mold 3. After the splicing is completed, the inner mold 2 is positioned and installed (the inner mold 2 is suspended between the two outer molds 3, generally on the corresponding frame 4. This is the existing technology and will not be described in detail). Finally, the end molds at both ends are spliced ​​to form a pouring space. The innovation of the embodiment of the present invention lies in that, during the process of splicing the formwork, the outer form 3 can be driven closer to the bottom form 1 through the first stroke of the driving mechanism (the first stroke of the driving mechanism can adopt the electric push rod in the prior art) to reduce friction and facilitate splicing of the two; after the concrete pouring is completed, the second stroke of the driving mechanism is run (the second stroke of the driving mechanism can adopt the vibration motor in the prior art), so that the outer form 3 can be driven to vibrate first and then the outer form 3 can be driven away from the bottom form 1 through the electric push rod to reduce the part where the concrete and the outer form 3 are bonded, thereby reducing the force between the concrete and the outer form 3, and then the outer form 3 is driven away from the bottom form 1 to complete the separation of the outer form 3.

[0035] An embodiment of the present invention provides a fully automatic mold for a concrete circular tube. When in use, a bottom mold 1, an end mold, an inner mold 2, and an outer mold 3 are assembled to form a pouring space for the concrete circular tube. After the concrete solidifies, the outer mold 3 can be driven to vibrate first through the second stroke of the driving mechanism. This can reduce the force between the outer mold 3 and the concrete, making it convenient to drive the outer mold 3 out of the concrete through the first stroke of the driving mechanism, thereby completing the demolding.

[0036] In another embodiment provided by the present invention, further, the driving mechanism includes a hydraulic rod 5 hinged on the frame 4, the other end of the hydraulic rod 5 is hinged to a driving block 6, a movable plate 7 is provided on the outer mold 3, a movable groove 8 is constructed on the movable plate 7, and the driving block 6 is slidably connected in the movable groove 8, and also includes a switching component, which is used to switch the position of the movable plate 7. Specifically, an active cavity 9 is constructed on the outer mold 3, and an opening is constructed at the bottom of the active cavity 9 for the hydraulic rod 5 to run in the opening, and the two ends of the hydraulic rod 5 are respectively hinged to the frame 4 and the driving block 6, so that the hydraulic rod 5 can run at multiple angles; the movable plate 7 is located in the active cavity 9 and has a first position and a second position. When the movable plate 7 is in the first position, the hydraulic rod 5 drives the driving block 6 to move in the movable groove 8 to the first stroke of the driving mechanism; when the movable plate 7 is in the second position, the hydraulic rod 5 drives the driving block 6 to move in the movable groove 8 to the second stroke of the driving mechanism; the switching component can adopt the electric push rod in the prior art. , to drive the moving plate 7 to switch positions; when the moving plate 7 is in the first position, the driving block 6 abuts against the end of the moving groove 8 close to the bottom mold 1, and the hydraulic rod 5 continues to extend to drive the outer mold 3 to move closer to the bottom mold 1; and when it needs to move away, the driving block 6 is driven to move to abut against the end of the moving groove 8 away from the bottom mold 1, and then the hydraulic rod 5 continues to contract to drive the outer mold 3 away from the bottom mold 1; when the moving plate 7 is in the second position, the driving block 6 moves in the moving groove 8 to drive a striking member to strike the outer mold 3 through the rocker assembly (the rocker assembly can convert linear motion into rotational power), thereby driving the outer mold 3 to vibrate.

[0037] Preferably, the driving mechanism includes a vibration component, which includes a connecting frame 10 fixed on the outer wall of the outer mold 3, a rotating shaft 11 rotatably connected to the connecting frame 10, an eccentric wheel 12 fixed on the rotating shaft 11, and a transmission component. In the second stroke, the driving block 6 drives the rotating shaft 11 to rotate through the transmission component. Specifically, the top of the movable cavity 9 also has an opening, so that the rotating shaft 11 at the bottom end of the connecting frame 10 can extend into the movable cavity 9; when the switching assembly drives the movable plate 7 to switch to the second position, the driving block 6 moves along the movable groove 8, which can drive the rotating shaft 11 to rotate through the transmission assembly, such as the combination of a friction wheel and a friction strip. Preferably, the transmission assembly includes a rack 13 fixed on the driving block 6 and a gear 14 fixed on the rotating shaft 11, and the rack 13 is arranged along the length direction of the movable groove 8; when the movable plate 7 is switched to the second position, the rack 13 on the driving block 6 engages with the gear 14 on the rotating shaft 11, and then the driving block 6 moves back and forth along the movable groove 8 to drive the rotating shaft 11 to rotate, thereby driving the eccentric wheel 12 to rotate, and the eccentric wheel 12 will generate vibration when rotating, thereby transmitting the vibration to various parts of the outer mold 3 through the connecting frame 10, thereby reducing the part where the concrete and the outer mold 3 are bonded, making it convenient for the outer mold 3 to be separated.

[0038] It should be noted that the vibration generated by the eccentric wheel 12 is related to the rotation speed of the rotating shaft 11. The driving block 6 is driven by the hydraulic rod 5 to move in the moving groove 8. The moving speed of the driving block 6 is basically determined within a range. In order to appropriately increase the rotation speed of the eccentric wheel 12, an acceleration mechanism can be set between the gear 14 and the eccentric wheel 12 to increase the rotation speed of the eccentric wheel 12 without changing the moving speed of the driving block 6, thereby obtaining a suitable vibration intensity. This is the existing technology and will not be repeated. When the eccentric wheel 12 vibrates, the connecting frame 10 and the outer mold 3 vibrate synchronously, which will affect the operation of other mechanisms in the active cavity 9. For this reason, the rotation speed of the eccentric wheel 12 needs to be controlled within a certain range to drive the outer mold 3 to vibrate while minimizing the impact of the vibration on other mechanisms.

[0039] As a replacement or parallel solution for the above-mentioned eccentric wheel 12 structure, further, the connecting frame 10 is connected to the first bracket 101 and the second bracket 102, and the rotating shaft 11 is rotatably connected to the connection between the first bracket 101 and the second bracket 102. The other ends of the first bracket 101 and the second bracket 102 are fixed on the outer wall of the outer mold 3. A plurality of knocking components are provided on the rotating shaft 11. The knocking components include a connecting gear 28 fixed on the rotating shaft 11. An incomplete gear 25 is rotatably connected to the connecting frame 10, and the incomplete gear 25 is engaged with the connecting gear 28. An elastic sheet 26 is fixed on one side of the incomplete gear 25, and a knocking block 27 is fixed at the end of the elastic sheet 26. A torsion spring is provided between the incomplete gear 25 and the connecting frame 10, and the torsion spring is used to force the knocking block 27 and the elastic sheet 26 to be between the first bracket 101 and the second bracket 102. Specifically, when the rotating shaft 11 rotates, the connecting gear 28 can drive the incomplete gear 25 to rotate, so as to drive the elastic sheet 26 and the knocking block 27 to move toward the first bracket 101 or the second bracket 102 (when the rotating shaft 11 rotates in different directions, the direction of movement of the knocking block 27 is also different, which is affected by the movement direction of the rack 13), thereby knocking the connecting frame 10 through the knocking block 27, thereby causing the connecting frame 10 and the outer mold 3 to vibrate to a certain extent. When the connecting gear 28 continues to rotate, the incomplete gear 25 will eventually disengage from the connecting gear 28, and the torsion spring will drive the knocking block 27 to be between the first bracket 101 and the second bracket 102, that is, through the torsion spring. The spring can drive the incomplete gear 25 closer to the connecting gear 28, thereby driving the incomplete gear 25 to rotate repeatedly when the connecting gear 28 continues to rotate (that is, the incomplete gear 25 repeatedly meshes with the connecting gear 28 and rotates under the drive of the connecting gear 28), thereby driving the knocking block 27 to repeatedly knock on the first bracket 101 or the second bracket 102, so that the outer mold 3 can vibrate continuously; the knocking block 27 and the eccentric wheel 12 can be used alone or in combination. If the two are used in combination, the eccentric wheel 12 will increase the swing amplitude of the elastic sheet 26, thereby increasing the force of the knocking block 27 knocking on the connecting frame 10, thereby increasing the vibration force of the outer mold 3.

[0040] In another embodiment provided by the present invention, a locking mechanism is further provided between the bottom mold 1 and the outer mold 3. When the outer mold 3 and the bottom mold 1 are in contact, the locking mechanism locks the outer mold 3 and the bottom mold 1. Specifically, when the driving mechanism drives the outer mold 3 to move to a position in contact with the bottom mold 1, the outer mold 3 is on the vehicle frame 4 and is only in contact with the bottom mold 1. At this time, the end molds have not yet been spliced, and the outer mold 3 has fewer stress points, which makes it easy to tilt. For this reason, a locking mechanism is provided, such as a lock structure in the prior art. When the bottom mold 1 and the outer mold 3 are in contact, the two are first preliminarily locked to facilitate subsequent splicing.

[0041] Preferably, the locking mechanism includes a locking rod 15 fixed to the bottom mold 1 and a locking groove constructed in the outer mold 3. Specifically, the locking rod 15 and the locking groove are both arranged along the movement direction of the outer mold 3 on the frame 4. When the outer mold 3 is about to be fitted with the bottom mold 1, the locking rod 15 is relatively inserted into the locking groove. When the outer mold 3 and the bottom mold 1 are fitted, the locking rod 15 is relatively fully inserted into the locking groove, thereby preliminarily locking the outer mold 3 and minimizing the possibility of tilting the outer mold 3.

[0042] Furthermore, a clamping block 16 is fixed on the movable plate 7 , a clamping slot 17 is configured on the locking rod 15 , a switching slot 20 is configured in the outer mold 3 , and the movable plate 7 is slidably connected in the switching slot 20 . When the movable plate 7 is at the bottom of the switching groove 20, it is in the first position; when the movable plate 7 is at the top of the switching groove 20, it is in the second position; when the movable plate 7 moves from the first position to the second position, the movable plate 7 moves from the bottom of the switching groove 20 to the top, and at the same time drives the card block 16 to move upward into the card slot 17, and when the movable plate 7 moves from the second position to the first position, the card block 16 is synchronously moved out of the card slot 17; the effect of such a setting is that the hydraulic rod 5 drives the driving block 6 to move in the movable groove 8 to run the second stroke or the first stroke. Therefore, when it runs the second stroke and drives the outer mold 3 to vibrate, the position of the outer mold 3 may move due to the vibration. For this purpose, the card block 16 and the card slot 17 are set. When the movable plate 7 moves from the first position to the second position, the position of the locking rod 15 is restricted by the card block 16 to minimize displacement or shaking of the outer mold 3 during vibration.

[0043] Preferably, the switching mechanism includes a baffle 18, and the baffle 18 is located in the locking groove. A first spring 19 is provided in the outer mold 3, which is used to force the baffle 18 to move out of the locking groove, and a second spring 21 is provided in the outer mold 3, which is used to force the block 16 to move into the slot 17. Specifically, the switching slot 20 is constructed in the movable cavity 9, and the movable plate 7 slides in the movable cavity 9 through the switching slot 20; the two ends of the first spring 19 are respectively fixed on the inner wall of the movable cavity 9 and the outer wall of the baffle 18, and the two ends of the second spring 21 are respectively fixed on the inner wall of the movable cavity 9 and the bottom wall of the movable plate 7; a connecting portion is constructed on the baffle 18, and the first spring 19 is fixed on the connecting portion, and the first spring 19 can force the baffle 18 to be in the locking groove and to resist the top end of the block 16; the effect of such a setting is that when the movable plate 7 is in the first position, the baffle 18 is at the top end of the block 16 to resist the block 16 and the position of the movable plate 7 are restricted, thereby limiting the movable plate 7 to the first position; when the driving block 6 moves along the movable groove 8 toward the side of the bottom mold 1, it will conflict with the inner wall of the movable groove 8 and force the movable plate 7 to move toward the side of the bottom mold 1, and at this time the movable plate 7 is restricted and cannot move along the switching groove 20 to the second position, so that when the driving block 6 moves, it drives the movable plate 7 to conflict with the inner wall of the switching groove 20 (that is, it conflicts with the inner wall of the active cavity 9), thereby driving the outer mold 3 and making the outer mold 3 approach the bottom mold 1 along the slide rail. When the outer mold 3 approaches the bottom mold 1, the locking rod 15 will be relatively inserted into the locking groove During this process, the locking rod 15 will squeeze the baffle 18 (the bottom wall of the baffle 18 is flush with the bottom wall of the locking rod 15), so that the baffle 18 squeezes the first spring 19 and moves into the locking groove (that is, moves into the active cavity 9). When the locking rod 15 contacts the baffle 18, the bottom end of the locking rod 15 simultaneously contacts the top end of the card block 16 until the locking rod 15 is relatively fully inserted into the locking groove (that is, when the outer mold 3 moves to a position that fits with the bottom mold 1). The position of the card block 16 corresponds to the position of the card slot 17. At this time, the card block 16 loses its restriction, allowing the movable plate 7 and the card block to move freely. The block 16 can move along the switching slot 20 under the action of the second spring 21, that is, the moving plate 7 moves from the first position to the second position, and the card block 16 is synchronously inserted into the card slot 17 until the card block 16 is fully inserted into the card slot 17, and the moving plate 7 moves to the top of the switching slot 20, so that the relative positions of the bottom mold 1 and the outer mold 3 can be locked while the bottom mold 1 and the outer mold 3 are fitted together, and the moving plate 7 will move from the first position to the second position when the two are locked, which is convenient for the subsequent vibration of the outer mold 3 through the driving block 6, and during the vibration process, the relative position of the outer mold 3 and the bottom mold 1 is always restricted.

[0044] Furthermore, a clamping member is included, which clamps the clamping block 16 and the locking rod 15 during the second stroke. Specifically, because one end of the hydraulic rod 5 is hinged to the driving block 6, its driving angle changes with the position of the driving block 6. When the movable plate 7 is in the first position, it is restricted by the baffle 18 and cannot move to the second position under the action of the second spring 21. However, when the movable plate 7 is in the second position, it is not restricted by other factors and can easily disengage from the second position. Therefore, a clamping member, such as an electromagnetic lock, is provided to clamp the clamping block 16 and the locking rod 15 during the second stroke.

[0045] Preferably, the clamping member includes a clamping groove 22 constructed on the clamping block 16. In the second stroke, the first spring 19 forces the baffle 18 to be inserted into the clamping groove 22; when the movable plate 7 moves from the first position to the second position, the driving block 6 is in the second stroke. At this time, the movable plate 7 drives the clamping block 16 to be inserted into the clamping groove 17. After the movable plate 7 moves to the second position, the position of the baffle 18 corresponds to the clamping groove 22, so that the baffle 18 can enter the clamping groove 22 under the action of the first spring 19. In this way, the relative position of the clamping block 16 and the locking rod 15 can be clamped by the baffle 18, thereby limiting the movable plate 7 to the second position.

[0046] Furthermore, it also includes a reset component, which drives the movable plate 7 to reset to the first position at the end of the second stroke. Specifically, when the movable plate 7 is in the second position, the driving block 6 moves along the movable groove 8, which is the second stroke. When the driving block 6 moves to the end of the second stroke, that is, when the driving block 6 moves from one end close to the bottom mold 1 to the other end (when the driving block 6 moves to the other end, the rack 13 and the gear 14 are disengaged), the movable plate 7 needs to be reset for the next use. For this purpose, a reset mechanism is provided (such as an electric push rod in the prior art, which is provided on the side of the baffle 18 away from the first spring 19, and when needed, the electric push rod is extended to contact the baffle 18 and disengage the baffle 18 from the clamping groove 22). At the end of the second stroke, the movable plate 7 is reset by the reset component, and when the movable plate 7 is reset, it can also drive the baffle 18 to move out of the clamping groove 22, and at the same time drive the clamping block 16 to move out of the clamping groove 17, so that the outer mold 3 can move away from the bottom mold 1 for demoulding.

[0047] Preferably, the reset assembly includes a reset rod 23 slidably connected to the outer mold 3 , the reset rod 23 is fixed to the baffle 18 , and a trigger portion 24 is configured at the top end of the reset rod 23 . Specifically, the reset rod 23 is fixed to the connecting portion of the baffle 18; the driving block 6 protrudes from the moving groove 8, and the trigger portion 24 is in the second stroke of the protruding portion of the driving block 6, that is, when the moving plate 7 is in the second position, the protruding portion of the driving block 6 can interfere with the trigger portion 24, and when the moving plate 7 moves to the first position, the trigger portion 24 is above the driving block 6, that is, when the moving plate 7 is in the first position, the driving block 6 will not interfere with the trigger portion 24; the end of the hydraulic rod 5 close to the frame 4 is lower than the other end; in the second stroke, the hydraulic rod 5 contracts to drive the driving block 6 to move to the side away from the bottom mold 1 until the driving block 6 moves to the end of the moving groove 8. In this process, the part of the driving block 6 protruding from the moving groove 8 will interfere with the trigger portion 24, thereby driving the trigger portion 24, the reset rod 23 and the baffle 18 to move along the movable cavity 9 to the side away from the bottom mold 1, and in the process of the movement of the baffle 18, the first spring 19 will be squeezed and released from the slot 17 The first spring 19 is used to return the outer mold 3 to the original position, and the second spring 19 is used to return the outer mold 3 to the original position, so that the outer mold 3 can be disengaged from the first position.
