Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated floor slab manufacturing, and in particular to a prefabricated floor slab forming mold and a forming process that are easy to demould. Background Art

[0002] As a core component of modern building industrialization, precast floor slabs achieve efficient manufacturing and quality control through factory-based prefabrication. These floor slabs, cast in standard factory buildings using reinforced concrete, overcome the bottlenecks of traditional cast-in-place processes limited by climate and site conditions. Precision molds and automated production lines ensure dimensional accuracy and structural stability.

[0003] In existing precast floor slab molds, after pre-curing, the slab is flipped 90 degrees to be demolded. A side panel of the mold, acting as the bottom panel, separates from the mold body and supports the slab, facilitating cutting. During demolding, the mold is hoisted and tilted upward by a lifting mechanism to separate the top and side walls from the slab. This can easily cause the slab to shift position during separation, leading to subsequent damage and deformation from collisions. Summary of the Invention

[0004] The purpose of the present invention is to provide a prefabricated floor slab forming mold that is easy to demould, so as to solve the problems of positional offset, damage and deformation that are likely to occur during the separation process of the prefabricated floor slab from the mold.

[0005] In order to achieve the above objectives, the present application discloses, on the one hand, a prefabricated floor slab forming mold that is easy to demould, comprising:

[0006] The mold body includes a base, a first baffle and a second baffle. The cross section of the base is U-shaped. The base includes a bottom plate and sidewall plates symmetrically arranged on both sides of the bottom plate. A partition is provided between the side wall plates, and the partition is parallel to the bottom plate. The first baffle and the second baffle are symmetrically arranged on both sides of the base. The first baffle end is provided with a bent edge, which is detachably mounted on the sidewall plate.

[0007] The mold separation assembly includes a swing arm, a driving cylinder and a locking plate. The swing arm is rotatably mounted on the base body. The driving cylinder is used to drive the swing arm to swing. A first bevel gear is sleeved on the first rotating shaft of the swing arm. A second rotating shaft is provided on the locking plate. The second rotating shaft is rotatably mounted on the base body. A second bevel gear is provided on the second rotating shaft. The second bevel gear is meshed with the first bevel gear, and the locking plate contacts the second baffle.

[0008] As a further description of the above technical solution:

[0009] The swing angle of the swing arm is 90 degrees.

[0010] As a further description of the above technical solution:

[0011] Symmetrically arranged driving cylinders are provided on both sides of the swing arm.

[0012] As a further description of the above technical solution:

[0013] Rollers are arranged under the seat body.

[0014] As a further description of the above technical solution:

[0015] Two lifting connection seats are arranged on the side wall plate.

[0016] As a further description of the above technical solution:

[0017] A connecting screw is also provided on the side wall plate, and a first waist-shaped hole corresponding to the position of the connecting screw is provided on the bent edge.

[0018] As a further description of the above technical solution:

[0019] A connecting head is provided on the piston rod of the driving cylinder, and the connecting head is slidably connected in the second waist-shaped hole on the swing arm.

[0020] On the other hand, the present application also discloses a prefabricated floor slab forming process that is easy to demould, comprising the following steps:

[0021] S1. The slurry is pre-formed in a cavity surrounded by the upper base, the first baffle, and the second baffle of the mold body, with the cavity opening facing upward;

[0022] S2. After the pre-curing is completed, the mold body is moved to the cutting trolley by the hoisting equipment. The mold body is turned 90 degrees to be demoulded. The second baffle of the mold body is placed on the cutting trolley as the bottom. The cutting trolley supports the mold body to avoid the locking plate.

[0023] S3, releasing the locking between the bent edge of the first baffle and the side wall plate of the seat body;

[0024] S4. The mold separation assembly is started, and the driving cylinder drives the swing arm to swing. The swing arm pushes up the first baffle, separating the first baffle from the precast floor slab. At the same time, the swing of the swing arm drives the first rotating shaft and the first bevel gear thereon to rotate, and the second bevel gear rotates accordingly, and drives the locking plate to rotate through the second rotating shaft. The locking plate disengages from under the second baffle, unlocking the second baffle and the base.

[0025] S5. Pull the base upwards, the base and the first baffle are separated from the prefabricated floor slab, and the prefabricated floor slab and the second baffle remain on the cutting trolley, thereby realizing the removal of the prefabricated floor slab.

[0026] To sum up, by adopting the technical scheme, the application has the beneficial effects:

[0027] 1、In the application, when the prefabricated floor is demoulding with the mould body, the mould separation assembly releases the locking of the second baffle and the seat body while jacking up the first baffle, effectively simplifying the mould separation assembly.

[0028] 2、In the application, the first baffle above the mould body and the seat body are step by step separated from the prefabricated floor, which facilitates to improve the demoulding effect and prevent the prefabricated floor from position deviation and damage deformation during demoulding.

[0044] The mold separation assembly 4 comprises a swing arm 41, a driving cylinder 42 and a locking plate 43, the swing arm 41 is rotatably arranged on the seat body 1, the driving cylinder 42 is used for driving the swing arm 41 to swing, a first bevel gear 411 is sleeved on a first rotating shaft of the swing arm 41, a second rotating shaft is arranged on the locking plate 43, the second rotating shaft is rotatably arranged on the seat body 1, a second bevel gear 431 is arranged on the second rotating shaft, the second bevel gear 431 is engaged with the first bevel gear 411, and the locking plate 43 is in contact with the second baffle 3.

[0045] The swing angle of the swing arm 41 is 90 degrees. When the swing arm 41 swings by 90 degrees, the locking plate 43 rotates by 90 degrees and is separated from the second baffle 3. The 90-degree swing of the swing arm 41 also makes the first baffle 2 reset after going up, so that the first baffle 2 does not fall when the seat body 1 is demolded subsequently.

[0046] The driving cylinders 42 are symmetrically arranged on both sides of the swing arm 41, so that the lifting degree of the swing arm 41 is ensured and the demolding of the first baffle 2 and the prefabricated floor is effectively realized.
