Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a precast slab casting mold. Background Technology

[0002] As is well known, precast concrete slabs are a type of precast component widely used in construction engineering. They are mainly prefabricated in factories or specific prefabrication sites, using concrete as the main material for casting and forming slab-shaped building components. During the manufacturing process, cement, sand, water, and admixtures added as needed are mixed in a certain proportion to form concrete, which is then poured into specially designed molds.

[0003] However, traditional precast slab casting molds are usually monolithic, with rigid connections between the parts. Once the mold is formed, the size of its internal cavity is basically fixed, which lacks flexibility in handling different types of buildings. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a precast slab casting mold. When using this precast slab casting mold, rotating the knob drives the bidirectional threaded rod on one side to rotate, which in turn drives the transmission wheel and the synchronous belt to rotate, thereby driving the bidirectional threaded rod on the other side to rotate as well. This, in turn, drives the threaded sleeve blocks and the sliding plate at both ends to move in opposite directions. The width of the mold frame can be adjusted as needed, and the mold can flexibly change the width of the mold frame according to specific construction requirements to produce precast slabs of various widths.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A precast slab casting mold includes a mold frame. A T-shaped box is fixedly connected to the rear end of the upper surface of the mold frame. T-shaped grooves are formed on both sides of the outer wall of the T-shaped box. A bidirectional threaded rod is rotatably connected to the inner wall of the front and rear ends of the T-shaped grooves on both sides. Threaded sleeve blocks are fitted on the front and rear ends of the bidirectional threaded rod. A connecting rod is fixedly connected to the side of the threaded sleeve block away from the center of the mold frame. A sliding plate is fixedly connected to the lower end of the outer wall of the adjacent side of the connecting rod.

[0007] A base plate is provided at the lower end of the inner wall of the mold frame. Support seats are threadedly connected to the four corners of the lower surface of the base plate. Mounting frames are fixedly connected to both sides of the lower surface of the mold frame. A sliding groove is provided on the outer wall of the mounting frame, and a support plate is slidably connected inside the sliding groove.

[0008] Compared with existing precast slab casting molds, this precast slab casting mold, when used, allows the base plate to be removed by pulling out the support plate and rotating multiple support seats at the same time, making the base plate detach from one side of the base plate. This facilitates the demolding of the cast precast slab, resulting in higher practical performance.

[0009] Furthermore, a sealing plate is fixedly connected to the outer wall of the slide plate at the end away from the center of the mold frame;

[0010] The above technical solution facilitates the flow of concrete during pouring by using a sealing plate.

[0011] Furthermore, a transmission wheel is fitted onto the rear end of the outer wall of the bidirectional threaded rod, and a synchronous belt is fitted onto the outer wall of the transmission wheel;

[0012] The above technical solution facilitates the simultaneous rotation of the two bidirectional threaded rods on both sides via the transmission wheel and synchronous belt.

[0013] Furthermore, a knob is fixedly connected to the rear end of the bidirectional threaded rod body on one side, and the knob passes through the T-shaped box to the outside of the T-shaped box;

[0014] The above technical solution allows for easy rotation of a two-way threaded rod on one side via a knob.

[0015] Furthermore, the threaded sleeves are all slidably connected to the inner walls of the T-shaped grooves on both sides;

[0016] With the above technical solution, the threaded sleeves are slidably connected to the inner walls of the T-shaped grooves on both sides, which facilitates the opposing movement of the threaded sleeves and the connecting rod.

[0017] Furthermore, the lower end of the skateboard is slidably connected to the upper end of the base plate;

[0018] The above technical solution allows for easy adjustment of the mold frame's width by sliding the lower end of the slide plate onto the upper end of the base plate.

[0019] Furthermore, each of the outer walls of the adjacent side of the support base is fixedly connected with abutment plates, and the upper ends of the abutment plates are in close contact with the lower surface of the base plate.

[0020] The above technical solution allows for easy support of the four corners at the bottom of the base plate using the abutment plate.

[0021] Furthermore, the upper surface of the support plate is in close contact with the middle of the lower surface of the base plate;

[0022] The above technical solution facilitates the support of the base plate using a support plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes a precast slab casting mold. Compared with existing precast slab casting molds, when using this precast slab casting mold, rotating the knob drives the double-threaded rod on one side to rotate, which in turn drives the transmission wheel and the synchronous belt to rotate, thereby driving the double-threaded rod on the other side to rotate as well. This, in turn, drives the threaded sleeve blocks and the sliding plate at both ends to move in opposite directions. The width of the mold frame can be adjusted as needed. The mold can flexibly change the width of the mold frame according to specific construction requirements to produce precast slabs of various width specifications.

[0025] 2. The precast slab casting mold proposed in this utility model, compared with the existing precast slab casting mold, allows the base plate to be removed by pulling out the support plate and rotating multiple support seats at the same time, making the base plate easy to demold the cast precast slab after casting. It has high practical performance. Attached Figure Description

Threaded sleeve blocks 23 are sleeved on the front and rear ends of the bidirectional threaded rod 22. A connecting rod 24 is fixedly connected to the side of the threaded sleeve block 23 away from the center of the mold frame 1, and a sliding plate 25 is fixedly connected to the lower end of the outer wall of the adjacent side of the connecting rod 24.

[0037] A base plate 3 is provided at the lower end of the inner wall of the mold frame 1. Support seats 31 are threadedly connected to the four corners of the lower surface of the base plate 3. Mounting frames 33 are fixedly connected to both sides of the lower surface of the mold frame 1. A sliding groove 34 is provided on the outer wall of the mounting frame 33. A support plate 35 is slidably connected inside the sliding groove 34.

[0038] Compared with existing precast slab casting molds, this precast slab casting mold can be used by pulling out the support plate 35 while rotating multiple support seats 31 so that the abutment plate 32 is separated from one side of the base plate 3, which can remove the base plate and facilitate the demolding of the cast precast slab. It has high practical performance.

[0039] A sealing plate 26 is fixedly connected to the outer wall of the slide plate 25 at the end away from the center of the mold frame 1. The sealing plate 26 facilitates the flow of concrete during pouring. A transmission wheel 27 is sleeved on the rear end of the outer wall of the bidirectional threaded rod 22. A synchronous belt 28 is sleeved on the outer wall of the transmission wheel 27. The transmission wheel 27 and the synchronous belt 28 facilitate the rotation of the two bidirectional threaded rods 22 on both sides. A knob 29 is fixedly connected to the rear end of the body of one side of the bidirectional threaded rod 22. The knob 29 passes through the T-shaped box 2 to the outside of the T-shaped box 2. The knob 29 facilitates the rotation of the one side of the bidirectional threaded rod 22. The threaded sleeve block 23 is slidably connected to the inner wall of the T-shaped groove 21 on both sides. Block 23 is slidably connected to the inner wall of the T-shaped groove 21 on both sides, which facilitates the opposing movement of the threaded sleeve block 23 and the connecting rod 24. The lower end of the slide plate 25 is slidably connected to the upper end of the base plate 3. The sliding connection between the lower end of the slide plate 25 and the upper end of the base plate 3 facilitates the adjustment of the width of the mold frame 1. The outer wall of the adjacent side of the support base 31 is fixedly connected with the abutment plate 32.

The abutment plate 32 facilitates the support of the four corners at the lower end of the base plate 3. The upper surface of the support plate 35 is tightly attached to the middle of the lower surface of the base plate 3. The support plate 35 facilitates the support of the base plate 3.

[0040] Working principle: During use, multiple support seats 31 are rotated so that their abutment plates 32 abut against the base plate 3. The support plate 35 passes through the slide groove 34 to support the middle of the base plate 3, thereby installing the base plate 3. By rotating the knob 29, the double-threaded rod 22 on one side is rotated, which in turn drives the transmission wheel 27 and the synchronous belt 28 to rotate. This drives the double-threaded rod 22 on the other side to rotate as well, thereby driving the threaded sleeve blocks 23 at both ends and the sliding plate 25 to move in opposite directions. The width of the mold frame 1 can be adjusted as needed. The mold can flexibly change the width of the mold frame 1 according to specific construction requirements to produce precast slabs of various widths. By pulling out the support plate 35 and rotating the multiple support seats 31 so that their abutment plates 32 are disengaged from one side of the base plate 3, the base plate can be removed for easy demolding of the precast slab after pouring.
