Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rectangular mould formwork, specifically to a prefabricated rectangular pipe section formwork mould. BACKGROUND

[0002] In the existing technical field of prefabricated rectangular pipe section formwork moulds, the mould closing process usually involves a series of complex and time-consuming steps. These steps often require the operator to make gradual and fine adjustments to the mould to ensure that it can be accurately and tightly closed. Specifically, the mould closing process usually starts with an initial contact, at which point the two parts of the mould approach each other at a slow speed and low pressure to avoid impact and damage caused by excessive speed or pressure. As the mould gradually closes, the operator needs to continuously adjust the speed and pressure of the mould closing until the mould is completely closed and locked.

[0003] However, this traditional mould closing method has many shortcomings. First, the gradual mould closing process is time-consuming and inefficient, especially in large-scale production, which significantly increases production costs.

DETAILED DESCRIPTION

[0026] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0027] Referring to Figures 1-3 As shown in the figure, a formwork mold for prefabricated rectangular pipe sections comprises a base 1, a plurality of mold main bodies 2 and an operating platform main body 21 arranged on the base 1, and the mold main body 2 further comprises a clamping mechanism 3 and a mold stripping mechanism 4; the clamping mechanism 3 is arranged at the top end of the base 1, and the clamping mechanism 3 comprises a moving part 31 capable of being connected with the mold main body 2 and driving the plurality of mold main bodies 2 to relatively approach each other; the clamping mechanism 3 further comprises a driving mechanism 5 for driving the moving part 31 to relatively approach and move away; the mold stripping mechanism 4 is arranged at the top of the moving part 31 and has a plurality of mold stripping mechanisms 4, which are used to fix the mold main bodies 2 to be disassembled.

[0028] When the mold main body 2 needs to be poured on the steel cage frame on the base 1, the moving part 31 drives the plurality of mold main bodies 2 to move relatively close to each other through the driving mechanism 5, thereby realizing the automatic mold closing action of the mold main body 2, without the need to separately push one of the mold main bodies 2 to close the mold, improving the mold closing precision of the mold main body 2 and ensuring the unity of the mold closing action. Workers can work on the operating platform main body 21, and the upper end of the operating platform main body 21 can be provided with a guardrail for preventing workers from falling. The upper end of the base 1 is provided with an inner mold located at the middle of the plurality of mold main bodies 2, and the inner mold is used to pour concrete to form a complete mold.

[0029] Referring to Figure 3 and Figure 4 As shown in the figure, the driving mechanism 5 comprises a rotary driver 51, a rotating disc 52 and a hinged rod 53; the rotary driver 51 is arranged in the base 1 and located below the moving part 31; the rotating disc 52 is arranged at the output end of the rotary driver 51, and the rotating disc 52 is located inside the base 1; one end of the hinged rod 53 is rotationally connected with the rotating disc 52, and the other end of the hinged rod 53 is rotationally connected with the moving part 31; when the rotating disc 52 rotates, the moving part 31 can be driven to slide relatively close to or away from each other through the rotationally connected hinged rod 53.

[0030] When it is required to drive the plurality of moving parts 31 to relatively close, first, the rotating driver 51 is started and drives the rotating disc 52 to rotate, when the rotating disc 52 rotates, it can drive the plurality of articulated rods 53 rotatingly arranged to rotate, when the articulated rod 53 rotates, it can drive the moving part 31 rotatingly connected to slide.

[0031] As shown in Figure 4 and Figure 5 , the driving mechanism 5 further comprises a guide rod 54 and a shielding part 55; the guide rod 54 is arranged in the inside of the base 1, a plurality of guide rods 54 are equidistantly distributed along the arrangement direction of the moving part 31, and the moving part 31 is gap-fitted with the guide rod 54; the top of the base 1 is provided with a horizontal groove 11 for the moving part 31 to slide; the top of the base 1 is provided with an avoiding groove 12; the shielding part 55 is arranged on the moving part 31 and can be located in the avoiding groove 12 to slide, when the moving part 31 slides, it can drive the shielding part 55 to synchronously move, so that the shielding part 55 is always shielded above the horizontal groove 11.

[0032] When the moving part 31 slides, it can stably slide along the gap-fitted guide rod 54 and the horizontal groove 11, which ensures that the sliding process of the moving part 31 is more stable. When the plurality of moving parts 31 relatively close, it can drive the shielding part 55 fixedly connected thereto to slide along the avoiding groove 12 provided at the top of the base 1, so that the moving part 31 can drive the shielding part 55 to slide in the horizontal groove 11 and the avoiding groove 12 when relatively close or far away, so that the shielding part 55 is always located in the horizontal groove 11, which can avoid that the concrete residues will fall into the horizontal groove 11 when the mold is closed and demolded, thereby affecting the stable sliding of the moving part 31.

[0033] As shown in Figure 5 , the driving mechanism 5 further comprises a first sealing block 56 and a plugging block 57; the first sealing block 56 is arranged on both sides of the mold body 2, and the first sealing block 56 is provided with a plugging groove; the plugging block 57 is arranged on both sides of the mold body 2, when the mold body 2 is closed, it can drive the plugging block 57 to abut into the plugging groove provided on the first sealing block 56.

[0034] When the mold body 2 is closed under the driving of the moving part 31, the plugging block 57 can be tightly abutted in the plugging groove provided on the first sealing block 56, which can effectively prevent the concrete from leaking, thereby ensuring the pouring completeness of the concrete.

[0035] As shown in Figures 6-8As shown in the figure, the demolding mechanism 4 comprises a mounting plate 41, a telescopic cylinder 42 and a abutting part 43; the mounting plate 41 is arranged at the top end of the moving part 31 and has two; the telescopic cylinder 42 is arranged on the top plate of the mounting plate 41 and is above the moving part 31; the abutting part 43 is slidingly arranged on the mounting plate 41, and the abutting part 43 is connected with the output end of the telescopic cylinder 42.

[0036] When the demolding action is needed, first, the telescopic cylinder 42 is started and drives the abutting part 43 to move downward, when the abutting part 43 moves downward, the mold body 2 can be abutted on the moving part 31, at this time, the rotary driver 51 is started and drives the rotating disc 52 to rotate reversely, when the rotating disc 52 rotates reversely, the moving part 31 can be driven to slide relatively far away along the guide rod 54 through the hinge rod 53 arranged rotatably, and then the mold body 2 after closing and pouring can be automatically demolded.

[0037] Referring to Figure 7 and Figure 8 As shown in the figure, the demolding mechanism 4 further comprises an abutting block 44; the abutting block 44 is arranged below the abutting part 43 and is in a cylindrical shape; the mold body 2 is provided with an abutting groove 441 which is inserted and matched with the abutting block 44.

[0038] When the abutting part 43 moves downward, the abutting block can be engaged with the abutting groove arranged on the mold body 2, so that the mold body 2 is fixed on the moving part 31 by the abutting part 43 and the abutting block 44, at this time, the abutting of the mold body 2 is completed, and the difficulty of demolding caused by the adhesion of the concrete on the mold body 2 after pouring is effectively avoided. In order to avoid the displacement of the mold body 2 when moving on the moving part 31, when the mold is closed, the abutting part 43 can first engage the abutting block 44 on the mold.

[0039] The working principle is that when the plurality of moving parts 31 need to be driven to move relatively close, the rotary driver 51 is first started to rotate the rotating disc 52. With the rotation of the rotating disc 52, the plurality of articulated rods 53 rotate, and the articulated rods 53 are rotationally connected with the moving parts 31, so that the moving parts 31 can be driven to slide. The moving parts 31 stably slide along the clearance-fitted guide rods 54 and the horizontal groove 11, ensuring the stability of the sliding process. With the relative sliding of the plurality of moving parts 31, the shielding part 55 fixedly connected therewith slides along the avoiding groove 12 opened at the top of the base 1. In this way, when the moving parts 31 move relatively close or away, the shielding part 55 always slides in the horizontal groove 11 and the avoiding groove 12, avoiding the concrete residues from falling into the horizontal groove 11 during the mold closing and demolding, so as to not affect the stable sliding of the moving parts 31. When the mold body 2 is closed under the driving of the moving parts 31, the blocking block 57 abuts against the blocking groove opened in the first sealing block 56, effectively preventing the leakage of concrete and ensuring the integrity of the concrete pouring. When demolding is needed, the telescopic air cylinder 42 is first started to drive the abutting part 43 to move downward. During the downward movement of the abutting part 43, the mold body 2 is abutted against the moving parts 31. At this time, the rotary driver 51 is started again to drive the rotating disc 52 to rotate reversely. With the reverse rotation of the rotating disc 52, the moving parts 31 are driven by the articulated rods 53 to slide relatively away along the guide rods 54, so as to realize the automatic demolding of the mold body 2 after the mold closing and pouring. During the downward movement of the abutting part 43, the abutting block can also be driven to be engaged with the abutting groove opened in the mold body 2, so that the mold body 2 is fixed on the moving parts 31 by the abutting part 43 and the abutting block 44, and the abutting of the mold body 2 is completed. This effectively avoids the difficulty in demolding caused by the adhesion of the mold body 2 after the concrete pouring. In order to avoid the displacement of the mold body 2 when moving on the moving parts 31, the abutting part 43 can first engage the abutting block 44 to the mold when the mold closing is performed.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
