Description

Technical Field

[0001] This invention relates to the field of socket tube processing, and more specifically, to a combined mold for forming concrete socket tubes. Background Technology

[0002] Concrete socket pipes are a common type of pipe, consisting of a reinforced concrete pipe with a smaller inner diameter inserted into a reinforced concrete pipe with a larger outer diameter, with an appropriate gap between the inner and outer pipes. During the production process, modular molds are used as an aid. These molds are specialized forming equipment for the mass production of concrete socket pipes, composed of multiple detachable and combinable components that work together to achieve the casting, shaping, and demolding of the pipe.

[0003] However, in existing combined molds, because the mold is always in contact with the surface of the socket tube during demolding, the mold exerts a squeezing effect on the socket tube, thus increasing the resistance during demolding. How to solve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a combined mold for forming concrete socket pipes, which aims to solve the problem that existing socket pipes cannot be easily demolded from the mold.

[0005] This invention is implemented as follows:

[0006] This invention provides a combined mold for forming concrete socket pipes, including a base, a first mold, and a second mold. The first mold is snapped onto the top of the base, and the second mold is snapped onto the top of the base. The mold also includes:

[0007] A mold closing assembly is disposed on the surface of mold one, and the mold closing assembly is used to merge and fix mold one and mold two.

[0008] A separation component is disposed on the surface of the mold closing component, and the separation component is used to facilitate the operator to separate the merged mold one and mold two.

[0009] A support assembly is disposed on the surface of the base and is used to support mold one and mold two.

[0010] Preferably, the mold clamping assembly includes a first frame, a second frame, a slide rod, a housing, a moving rod, a first spring, a wedge block, and a slot. The first frame is fixedly connected to the surface of the second mold, the second frame is fixedly connected to the surface of the first mold, the slide rod is fixedly connected to the surface of the first frame, the housing is disposed outside the second frame, the moving rod is disposed on the outer wall of the housing, the first spring is fixedly connected to the inside of the housing, the wedge block is fixedly connected to the end of the moving rod away from the housing, and the slot is formed at the bottom of the slide rod.

[0011] Preferably, the bottom of the second frame has a notch, the slide rod is located inside the second frame and is slidably connected to the inner wall of the second frame, the outer shell is fixedly connected to the surface of the first mold, the surface of the outer shell has a track, one end of the moving rod passes through the outer shell and extends into the interior of the outer shell, and the moving rod is slidably connected to the inner wall of the outer shell through which it passes.

[0012] By adopting the above technical solution, the slide bar can move inside the second frame, and the moving rod can move inside the outer shell.

[0013] Preferably, the side of the spring away from the outer casing is fixedly connected to the side of the moving rod extending into the interior of the outer casing, and the wedge block is located in the slot and the notch, and is slidably connected to the slot and the notch respectively.

[0014] By adopting the above technical solution, the setting of spring one can drive the moving rod to reset, and the setting of wedge block can limit and fix the position of the sliding rod through the moving rod, notch and slot, thereby ensuring the connection effect between mold one and mold two.

[0015] Preferably, the separation assembly includes a bent rod, a rack, a fixed rod, a toothed ring, a housing, a telescopic rod, a second spring, a movable plate, a stop plate, and an air groove. The bent rod is fixedly connected to the surface of the movable rod, the rack is fixedly connected to the surface of the bent rod, the fixed rod is fixedly connected to the surface of the mold, the toothed ring is rotatably connected to one end of the fixed rod, the housing is fixedly connected to the interior of the frame, the telescopic rod is installed at one end of the housing, the second spring is fixedly connected to the inner wall of the housing, the movable plate is disposed inside the housing, the stop plate is fixedly connected to one end of the telescopic rod, and the air groove is formed inside the frame.

[0016] Preferably, the bent rod passes through the track and is slidably connected to the track surface, the toothed ring meshes with the rack, one end of the telescopic rod passes through the housing and extends into the interior of the housing, and the telescopic rod is slidably connected to the housing.

[0017] By adopting the above technical solution, when the bent rod moves, it can be driven by the track to move the moving rod inside the shell. When the toothed ring rotates, it can push the rack to move, and the telescopic rod can move inside the shell.

[0018] Preferably, the side of the spring away from the housing is fixedly connected to the outer wall of the movable plate, the telescopic rod extends to one end of the housing and is fixedly connected to the movable plate, the movable plate is slidably connected to the housing, and the abutment plate abuts against one end of the sliding rod.

[0019] By adopting the above technical solution, the second spring can pull the movable plate to move and reset inside the shell. When the telescopic rod moves, it can push the movable plate to adjust its position. When the slide rod moves inside the second frame, it can push the telescopic rod to move through the abutment plate.

[0020] Preferably, the support assembly includes a base plate, a slider, a slide rail, and a guide wheel. The base plate is mounted on the surface of the base, the slider is fixedly connected to the bottom of the mold, the slide rail is opened inside the base plate, and the guide wheel is rotatably connected to the inside of the base plate.

[0021] Preferably, the sliders are distributed at the bottom of mold one and the bottom of mold two, the sliders are slidably connected to the slide rails, the tops of the guide wheels abut against the bottoms of mold one and mold two respectively, and the slide rails and sliders are subjected to quenching treatment.

[0022] By adopting the above technical solution, the slider can move inside the slide rail, and the guide wheel facilitates the movement of mold one and mold two.

[0023] The beneficial effects of this invention are:

[0024] 1. Frame 1 and Frame 2 can be moved separately by sliding, so that Frame 1 and Frame 2 can move Mold 2 and Mold 1 respectively until the mold is separated from the base. At this time, the operator can use a forklift to move the base and the socket tube located on the top of the base, thus solving the problem that the existing socket tube cannot be easily demolded from the mold.

[0025] 2. By moving the bending rod, the bending rod will drive the wedge block to move through the moving rod until the wedge block separates from the slot. At this time, the second spring will push the abutment plate to move through the moving plate and the telescopic rod, so that the abutment plate pushes the slide rod to move. The slide rod drives the second mold through the first frame to move, so that the first mold and the second mold are separated, which facilitates the subsequent mold opening process of the combined mold. At the same time, the slide rod and the second frame in the mold closing assembly cooperate with the toothed ring-toothed rack linkage structure of the separation assembly to realize the synchronous separation of the first mold and the second mold, thus achieving the effect of rapid positioning and synchronous separation.

[0026] 3. During the separation process, mold one and mold two will move on the top of the base plate and come into contact with the surface of the guide wheel. At this time, the guide wheel will rotate on the top of the base plate under the friction of the mold, thereby reducing the frictional resistance generated when the mold moves on the top of the base plate, making it easier for operators to open and close the mold. The slide rail and slider of the support component are hardened, and with the rolling friction design of the guide wheel, the offset of the socket tube on the base is reduced after the mold is separated. It can be directly transferred by forklift without manual calibration, reducing subsequent adjustment procedures and thus reducing labor costs. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figures 1-8 A composite mold for forming concrete socket pipes includes a base 1, a first mold 2, and a second mold 3. The first mold 2 is snapped onto the top of the base 1, and the second mold 3 is snapped onto the top of the base 1. It also includes:

[0039] Mold closing assembly 4 is disposed on the surface of mold 1 2 and is used to merge and fix mold 1 2 and mold 2 3.

[0040] Separation component 5 is disposed on the surface of mold closing component 4. Separation component 5 is used to facilitate the operator to separate the merged mold 1 2 and mold 2 3.

[0041] Support component 6 is disposed on the surface of base 1 and is used to support mold 1 2 and mold 2 3.

[0042] The mold clamping assembly 4 includes a first frame 401, a second frame 402, a slide bar 403, a housing 404, a moving rod 405, a first spring 406, a wedge block 407, and a slot 408. The first frame 401 is fixedly connected to the surface of the second mold 3, the second frame 402 is fixedly connected to the surface of the first mold 2, the slide bar 403 is fixedly connected to the surface of the first frame 401, the housing 404 is disposed outside the second frame 402, the moving rod 405 is disposed on the outer wall of the housing 404, the first spring 406 is fixedly connected to the inside of the housing 404, the wedge block 407 is fixedly connected to the end of the moving rod 405 away from the housing 404, and the slot 408 is opened at the bottom of the slide bar 403.

[0043] It should be noted that: A notch is provided at the bottom of frame two 402; slide rod 403 is located inside frame two 402 and is slidably connected to the inner wall of frame two 402; slide rod 403 can move inside frame two 402; outer shell 404 is fixedly connected to the surface of mold one 2; a track is provided on the surface of outer shell 404; one end of moving rod 405 penetrates outer shell 404 and extends into the interior of outer shell 404; moving rod 405 is slidably connected to the inner wall of outer shell 404 through which it is penetrated; moving rod 405 can move within outer shell 402. The spring 406 moves inside the housing 404. The side of the spring 406 away from the housing 404 is fixedly connected to the side of the moving rod 405 that extends into the housing 404. The spring 406 can drive the moving rod 405 to reset. The wedge block 407 is located in the slot 408 and the notch, and is slidably connected to the slot 408 and the notch respectively. The wedge block 407 can limit and fix the position of the slide rod 403 through the moving rod 405, the notch and the slot 408, thereby ensuring the connection effect between mold 2 and mold 3.

[0044] The frame 1 401 and the frame 2 402 can be moved by sliding, so that the frame 1 401 and the frame 2 402 can move the mold 2 3 and the mold 1 2 respectively, until the mold is separated from the base 1. At this time, the operator can use a forklift to move the base 1 and the socket tube located on the top of the base 1, thus solving the problem that the existing socket tube cannot be easily demolded from the mold.

[0045] By sliding, mold 1 2 and mold 2 3 are pushed respectively, causing mold 1 2 and mold 2 3 to move frame 1 401 and frame 2 402 respectively. This causes slide rod 403 to slide into the interior of frame 2 402, and the inclined surface of wedge block 407 pushes wedge block 407 to slide and move into the notch until slide rod 403 moves to the designated position. At this time, slot 408 is located above wedge block 407. Then, driven by spring 1 406, wedge block 407 is pushed into slot 408 by moving rod 405, thus completing the mold closing operation between mold 1 2 and mold 2 3.

[0046] The separation assembly 5 includes a bent rod 501, a rack 502, a fixed rod 503, a toothed ring 504, a housing 505, a telescopic rod 506, a second spring 507, a movable plate 508, a stop plate 509, and an air groove 510. The bent rod 501 is fixedly connected to the surface of the movable rod 405, the rack 502 is fixedly connected to the surface of the bent rod 501, the fixed rod 503 is fixedly connected to the surface of the mold 2, the toothed ring 504 is rotatably connected to one end of the fixed rod 503, the housing 505 is fixedly connected to the inside of the frame 2 402, the telescopic rod 506 is installed at one end of the housing 505, the second spring 507 is fixedly connected to the inner wall of the housing 505, the movable plate 508 is disposed inside the housing 505, the stop plate 509 is fixedly connected to one end of the telescopic rod 506, and the air groove 510 is opened inside the frame 2 402.

[0047] It should be noted that: the bent rod 501 passes through the track and is slidably connected to the track surface. When the bent rod 501 moves, it can drive the moving rod 405 to move inside the housing 404 via the track. The toothed ring 504 meshes with the rack 502. When the toothed ring 504 rotates, it can push the rack 502 to move. One end of the telescopic rod 506 passes through the housing 505 and extends into the housing 505. The telescopic rod 506 is slidably connected to the housing 505 and can move inside the housing 505. The spring 507 is away from the housing 504. One side of 5 is fixedly connected to the outer wall of the movable plate 508. The second spring 507 can pull the movable plate 508 to move and reset inside the housing 505. The telescopic rod 506 extends to one end of the housing 505 and is fixedly connected to the movable plate 508. The movable plate 508 is slidably connected to the housing 505. When the telescopic rod 506 moves, it can push the movable plate 508 to adjust its position. The abutment plate 509 abuts against one end of the slide rod 403. When the slide rod 403 moves inside the frame 402, it can push the telescopic rod 506 to move through the abutment plate 509.

[0048] By moving the bending rod 501, the bending rod 501 will drive the wedge block 407 to move through the moving rod 405 until the wedge block 407 separates from the slot 408. At this time, the second spring 507 will push the abutment plate 509 to move through the moving plate 508 and the telescopic rod 506, so that the abutment plate 509 pushes the slide rod 403 to move. The slide rod 403 drives the mold 2 3 to move through the frame 1 401, so that a gap is created between the mold 1 2 and the mold 2 3, which facilitates the subsequent mold opening process of the combined mold. At the same time, the slide rod 403 and the frame 2 402 in the mold closing assembly 4 cooperate with the toothed ring 504-tooth rack 502 linkage structure of the separation assembly 5 to realize the synchronous separation of the mold 1 2 and the mold 2 3, thereby achieving the effect of rapid positioning and synchronous separation.

[0049] When mold opening is required, the bending rod 501 on one side is pushed to move, causing the rack 502 to pull the bending rod 501 on the other side through the toothed ring 504. This causes the bending rod 501 to slide the wedge block 407 through the moving rod 405 until the wedge block 407 separates from the slot 408. At this time, the spring 507 will push the telescopic rod 506 to reset through the moving plate 508. When the telescopic rod 506 moves, it will push the slide rod 403 to move through the abutment plate 509. At this time, a gap will be generated between mold 1 2 and mold 2 3. By moving the frame 1 401 and the frame 2 402, mold 1 2 and mold 2 3 can be completely separated. The base 1 and the socket tube can then be moved together by a forklift.

[0050] The support assembly 6 includes a base plate 601, a slider 602, a slide rail 603, and a guide wheel 604. The base plate 601 is mounted on the surface of the base 1, the slider 602 is fixedly connected to the bottom of the mold 2, the slide rail 603 is opened inside the base plate 601, and the guide wheel 604 is rotatably connected to the inside of the base plate 601.

[0051] It should be noted that: sliders 602 are distributed at the bottom of mold 1 2 and mold 2 3. Slider 602 is slidably connected to slide rail 603. Slider 602 can move inside slide rail 603. The top of guide wheel 604 abuts against the bottom of mold 1 2 and mold 2 3 respectively. The guide wheel 604 is designed to facilitate the movement of mold 1 2 and mold 2 3. Slide rail 603 and slider 602 are hardened.

[0052] During the separation process, molds 1 (2) and 2 (3) will move on top of the base plate 601 and come into contact with the surface of the guide wheel 604. At this time, the guide wheel 604 will rotate on top of the base plate 601 under the friction of the mold, thereby reducing the frictional resistance generated when the mold moves on top of the base plate 601, making it easier for operators to open and close the mold. The slide rail 603 and slider 602 of the support component 6 are hardened. Combined with the rolling friction design of the guide wheel 604, the offset of the socket tube on the base 1 is reduced after the mold is separated. It can be directly transported by forklift without manual calibration, reducing subsequent adjustment procedures and thus reducing labor costs.

[0053] When mold 1 2 and mold 2 3 are moved by the traction of frame 1 401 and frame 2 402, mold 1 2 and mold 2 3 will move on the surface of guide wheel 604, and drive slider 602 to move inside slide rail 603 until the position adjustment of mold 1 2 and mold 2 3 is completed.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
