Description

Technical Field

[0001] This utility model relates to the field of casting auxiliary tools technology, specifically to a casting mold for asphalt concrete slabs. Background Technology

[0002] Asphalt concrete slab casting molds are specialized tools used for the precise shaping of asphalt concrete slabs. They are typically made of strong and heat-resistant materials, such as steel, and come in specific shapes and sizes to meet diverse engineering needs. Their rationally designed internal structure ensures even distribution and smooth filling of the asphalt concrete during pouring, effectively controlling the thickness and flatness of the slab. This guarantees stable quality and compliance with engineering standards for the finished asphalt concrete slabs, playing a crucial role in many fields involving asphalt concrete slab construction, such as roads and buildings.

[0003] The problem with existing technology is that in the current asphalt concrete slab pouring process, the usual practice is to pour the asphalt concrete mixture into a mold of fixed size for curing to form slabs of the target size. However, this fixed-size mold design cannot be flexibly adjusted to meet the diverse size requirements of asphalt concrete slabs for different engineering projects. When the required slab size is smaller than the mold, the excess part often has to be discarded, resulting in material waste. When the required slab size is larger than the mold, it is impossible to directly produce slabs that meet the requirements.

[0004] Therefore, this application is hereby submitted. Utility Model Content

[0009] In another preferred embodiment, the middle of the push-pull slider is hollowed out to form a cavity, which extends along the axial direction of the push-pull screw to form a groove. A slide bar protrudes from the side wall of the groove and extends along the axial direction of the push-pull screw. A fixed seat is provided inside the groove, and the bottom of the fixed seat is fixedly connected to the worktable. Limiting grooves are opened on opposite sides of the fixed seat, and each limiting groove corresponds to a slide bar. The slide bar is slidably engaged within its corresponding limiting groove. The motor is located on the fixed seat. The push-pull screw is located inside the groove, and its outer end penetrates the groove wall and is screwed in. A positioning block is provided at the outer end of the push-pull screw. When the positioning block abuts against the push-pull slider, the casting area is at its maximum size.

[0010] In another preferred embodiment, when the pouring area is at its maximum size, the fixing seat is aligned with the center of the corresponding template.

[0011] In another preferred embodiment, the outer wall of the template is provided with a horizontal slide rail, the slide rail is slidably connected to a slide plate, and the slide plate is connected to the corresponding push-pull slider.

[0012] In another preferred embodiment, the top and bottom of the slide rail are respectively provided with horizontally extending adjustment grooves, and the top and bottom of the slide plate are respectively provided with claws that match the adjustment grooves, so that the slide plate is C-shaped, and the slide plate is slidably engaged with the adjustment grooves by the claws.

[0013] In another preferred embodiment, the middle part of the slide plate has an insertion hole along the thickness direction, and a fixing block is detachably inserted into the insertion hole; the middle part of the slide rail has multiple fixing slots, all of which are evenly spaced along the horizontal direction, and the fixing block can be inserted into any one of the fixing slots to limit the sliding of the slide plate and the slide rail.

[0014] In another preferred embodiment, a support frame is fixedly connected to the side of the slide away from the slide rail, and an adjustment block is slidably connected to the support frame, with the sliding direction being the same as the thickness direction of the slide; the fixed block is fixedly connected to the adjustment block on the side away from the slide rail.

[0015] In another preferred embodiment, the support frame is U-shaped, and the open end of the support frame is fixedly connected to the side of the slide plate away from the slide rail; the adjusting block is slidably embedded in the support frame, and the top and bottom of the adjusting block contact the top wall and bottom wall of the support frame, respectively; the width of the adjusting block is less than or equal to the width of the support frame, so that the adjusting block is disposed in the support frame.

[0018] This utility model discloses an asphalt concrete slab casting mold. By setting up a workbench and four templates, a rectangular casting area is formed to achieve the basic function of asphalt concrete slab casting. Furthermore, by setting the four templates to slide along the work plane, the positional relationship of the four templates is restricted. Specifically, each template abuts against two adjacent templates through its side walls and inner walls, allowing each template to slide in two directions: horizontally along its plane and along its thickness. This combined sliding in two directions allows the length and width of the casting area formed by the four templates to be adjusted according to actual needs. A push-pull mechanism controls the independent sliding of each template, replacing manual template adjustment and improving efficiency and accuracy. Through the combination of these features, this asphalt concrete slab casting mold effectively solves the problem that existing asphalt concrete slab casting molds cannot adaptively adjust the casting size according to actual needs.

Detailed Implementation

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0030] like Figures 1 to 5As shown, this embodiment provides an asphalt concrete slab casting mold, including: a workbench 10, the top surface of which is provided with a working plane, the working plane being horizontally arranged; secondly, four templates 20, which are slidably disposed on the working plane, the four templates 20 forming a rectangular casting area, each template 20 abutting against two adjacent templates 20 through its sidewalls and inner walls, so that the length and width of the casting area can be adjusted by sliding the templates 20; thirdly, a push-pull mechanism, which is fixedly connected to the workbench 10, the push-pull mechanism enabling each template 20 to slide along the working plane, thereby expanding or shrinking the casting area.

[0031] The asphalt concrete slab casting mold disclosed in this embodiment, by setting up a workbench 10 and four templates 20, encloses a rectangular casting area to achieve the basic function of asphalt concrete slab casting. Based on this, the four templates 20 are slidably positioned relative to the work plane to restrict their positional relationship. Each template 20 abuts against adjacent templates 20 via its side and inner walls, allowing each template 20 to slide in two directions: horizontally along its plane and horizontally along its thickness. This combined sliding in two directions allows for adjustment of the length and width of the casting area formed by the four templates 20, enabling the size of the casting area to be adjusted according to actual needs. A push-pull mechanism controls the independent sliding of each template 20, replacing manual adjustment and improving efficiency and accuracy. Through the combined effect of these features, this asphalt concrete slab casting mold effectively solves the problem that existing asphalt concrete slab casting molds cannot adaptively adjust the casting dimensions according to actual needs.

[0032] To further explain the specific structure of the push-pull mechanism, the push-pull mechanism includes four push-pull sliders 30, which correspond one-to-one with the four templates 20 and are slidably connected to the outer wall of the corresponding template 20 in the horizontal direction. The push-pull sliders 30 are slidably connected to the worktable 10, and the sliding direction is perpendicular to the corresponding template 20. Each push-pull slider 30 is screwed with a push-pull screw 31, which is rotatably connected to the worktable 10 and axially limited. The push-pull screw 31 is driven by a motor 32, which is fixedly connected to the worktable 10.

[0033] With the above settings, when the size of the pouring area needs to be adjusted, the motor 32 drives the push-pull screw 31 to rotate. Since the push-pull screw 31 is rotatably connected to the worktable 10 and axially limited, the push-pull screw 31 only rotates and does not move axially. At this time, through the threaded connection between the push-pull screw 31 and the push-pull slider 30, the push-pull slider 31 can be driven to move axially along the push-pull screw 31, thereby driving the template 20 connected to the push-pull slider 30 to slide along the thickness direction, thereby changing the length and width of the pouring area. On this basis, since the push-pull slider 30 is horizontally slidably connected to the template 20, after the length and width of the pouring area are adjusted, the template 20 is moved horizontally along the plane where the template 20 is located, and the four templates 20 are tightly abutted against each other, thus sealing the pouring area to meet the pouring conditions.

[0034] To further explain the connection structure between the push-pull slider 30 and the worktable 10, the middle of the push-pull slider 30 is hollowed out to form a cavity. The cavity extends axially along the push-pull screw 31 to form a groove. A slide bar 301 protrudes from the side wall of the groove and extends axially along the push-pull screw 31. A fixed seat 33 is provided inside the groove. The bottom of the fixed seat 33 is fixedly connected to the worktable 10. Limiting openings are provided on opposite sides of the fixed seat 33. The groove 331 corresponds one-to-one with the slide bar 301, and the slide bar 301 is slidably locked in the corresponding groove 331; the motor 32 is mounted on the fixed base 33; the push-pull screw 31 is mounted in the slide groove, and the outer end of the push-pull screw 31 passes through the groove wall of the slide groove and is screwed in; the outer end of the push-pull screw 31 is provided with a positioning block 311; when the positioning block 311 abuts against the push-pull slider 30, the casting area is at its maximum size.

[0035] With the above settings, on the one hand, the sliding cooperation between the limiting groove 331 of the fixed seat 33 and the slide bar 301 is used to limit the rotation of the push-pull slider 30 and realize the axial movement along the push-pull screw 31.

[0036] It should be noted that, in order to ensure the balance of the force exerted by the push-pull mechanism on the part of the template 20 surrounding the pouring area, when the pouring area is at its maximum size, the fixing seat 33 is aligned with the middle part of the corresponding template 20.

[0037] To further explain the horizontal sliding structure of the push-pull slider 30 and the template 20, the outer wall of the template 20 is provided with a horizontal slide rail 21, and the slide rail 21 is slidably connected to a slide plate 22, which is connected to the corresponding push-pull slider 30.

[0038] To further explain the sliding connection structure of the slide rail 21 and the slide plate 22, the top and bottom of the slide rail 21 are respectively provided with horizontally extending adjustment grooves 211, and the top and bottom of the slide plate 22 are respectively provided with claws 221 that match the adjustment grooves 211, so that the slide plate 22 is C-shaped, and the slide plate 22 is slidably engaged with the adjustment grooves 211 by the claws 221.

[0039] The above settings allow the skateboard 22 to be secured to the slide rail 21, effectively improving the structural stability of the sliding structure and freeing up space in the middle of the skateboard 22 to lay the foundation for the subsequent installation of the fixing block 222.

[0040] To limit the sliding of the slide plate 22 and the slide rail 21, the slide plate 22 has an insertion hole in the middle along the thickness direction, and a fixing block 222 is detachably inserted into the insertion hole; the slide rail 21 has multiple fixing slots 212 in the middle, all of which are evenly spaced in the horizontal direction, and the fixing block 222 can be inserted into any one of the fixing slots 212 to limit the sliding of the slide plate 22 and the slide rail 21.

[0041] With the above settings, when adjustment is needed, the fixing block 222 is pulled out from the fixing groove 212, and then the slide plate 22 can slide along the slide rail 21. After the adjustment is completed, the fixing block 222 is inserted into the fixing groove 212 through the insertion hole, and the slide plate 22 and the slide rail 21 are limited again.

[0042] To prevent the fixing block 222 from falling off, a support frame 23 is fixedly connected to the side of the slide plate 22 away from the slide rail 21. The support frame 23 is slidably connected to an adjustment block 231, and the sliding direction is the same as the thickness direction of the slide plate 22. The side of the fixing block 222 away from the slide rail 21 is fixedly connected to the adjustment block 231.

[0043] With the above setup, the support frame 23 provides structural support for the adjustment block 231 while limiting its movement, thereby indirectly limiting the insertion and removal of the fixing block 222 and effectively preventing it from falling off.

[0044] To further explain the movement limiting structure of the support frame 23 for the adjusting block 231, the support frame 23 is U-shaped, and the open end of the support frame 23 is fixedly connected to the side of the slide plate 22 away from the slide rail; the adjusting block 231 is slidably embedded in the support frame 23, and the top and bottom of the adjusting block 231 contact the top wall and bottom wall of the support frame 23, respectively; the width of the adjusting block 231 is less than or equal to the width of the support frame 23, so that the adjusting block 231 is disposed in the support frame 23.

[0045] By utilizing the length of the internal space of the U-shaped support frame 23, the movement distance of the adjustment block 231 is limited, thereby achieving movement limitation and indirectly limiting the movement of the fixed block 222.

[0046] To facilitate the movement of the adjusting block 231, adjusting posts 232 are symmetrically protruding on both sides of the adjusting block 231 in the width direction; the top of the support frame 23 is vertically rotatably connected to an adjusting shaft 24, the adjusting shaft 24 has an external thread and is screwed to a lifting plate 25, the lifting plate 25 is vertically connected to two opposite sides of a limiting rotating plate 26, the distance between the two limiting rotating plates 26 matches the width of the support frame 23, the limiting rotating plate 26 has an inclined adjusting sliding hole 261, the adjusting sliding hole 261 passes through the limiting rotating plate 26 in the thickness direction; the adjusting sliding hole 261 corresponds one-to-one with the adjusting post 232, the adjusting post 232 is slidably inserted into the corresponding adjusting sliding hole 261; the top of the adjusting shaft 24 is provided with an adjusting knob 241.

[0047] With the above settings, rotating the adjustment knob 241 drives the adjustment shaft 24 to rotate. Since it is rotatably connected to the support frame 23, it only rotates relative to the support frame 23 and moves axially to a limited position. By screwing it into the lifting plate 25, the lifting plate 25 can be driven to rise and fall. At this time, the limiting plate 26 will restrict the lifting plate 25 from unnecessary rotation, so that the lifting plate 25 only rises and falls stably. During the process, the lifting plate 25 drives the limiting plate 26 to rise and fall synchronously. The limiting plate 26 drives the adjustment column 232 to move along it through the adjustment sliding hole 261. Since the adjustment sliding hole 261 is an inclined hole, it has a horizontal component displacement, thereby driving the adjustment block 231 to move horizontally through the adjustment column 232.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
