[0002] During the construction process of building engineering, according to the specification requirements, a concrete lintel must be set at the top of the distribution box in a residential household. In order to avoid damaging the masonry quality at the lintel position and prevent the lintel quality from not meeting the requirements due to the inability to vibrate the lintel concrete or chisel the threading pipe groove during the cast-in-place concrete lintel, relevant construction gradually adopts the installation of precast concrete lintels with threading pipe grooves reserved at the corresponding positions of the masonry to complete. The concrete lintel can be mass-produced through a supporting mold.

[0003] The Chinese patent document with the authorization announcement number of CN216707846U discloses a variable-length lintel precast mold, which adjusts the position of the lintel mold end plate on the lintel mold side plate according to the specifications of the precast lintel through an adjustment and limit mechanism that can adjust and limit the lintel mold end plate at the top of the lintel mold end plate, so that the lintel mold can be applicable to the precast of different specifications of lintels.

[0004] However, in the prior art, although a single set of mold can manufacture lintels of multiple specifications, the end plate can only be fixed at a specific position, resulting in the limitation that the length of the mold cavity still cannot be arbitrarily adjusted to the required length. Therefore, a pouring mold for a distribution box concrete lintel is proposed. Content of the Utility Model

[0026] The present utility model will be further described below with reference to the drawings through embodiments.

[0027] As Figures 1 - 5 shown, a casting mold for a concrete lintel of a distribution box includes a mold main body 1 that enables the convenient demolding of the cast concrete lintel. A fixed head component 2 is provided on one side of the mold main body 1 to block one end of the mold main body 1 at a fixed position, and a movable head component 3 is provided on the other side of the mold main body 1 to be able to move horizontally within a certain distance range arbitrarily, so that the volume of the mold cavity of this mold changes accordingly.

[0028] In this embodiment: The mold body 1 includes a mold base 101. An insertion slot 102 is integrally formed on the mold base 101. Movable side plates 103 are movably connected to the front and rear of the mold base 101. A pull handle 104 is fixedly connected to the movable side plate 103. The mold base 101 is rotatably connected to the movable side plate 103. The mold base 101 and the movable side plate 103 that can rotate relative to the mold base 101 cooperate with the first end head plate 201 and the second end head plate 301 to form the main part of the mold that is convenient for mold removal. The insertion slot 102 provides an insertion area for the first end head plate 201, enabling the first end head plate 201 to be stably arranged between the mold base 101 and the movable side plate 103. The pull handle 104 enables the user to conveniently rotate the movable side plate 103 relative to the mold base 101 after removing the first end head plate 201.

[0029] In this embodiment: The fixed end head assembly 2 includes a first end head plate 201 movably connected between the mold base 101 and the movable side plate 103. Armrest rods 202 are fixedly connected to the front and rear of the first end head plate 201. The mold base 101 and the movable side plate 103 are both slidably connected to the first end head plate 201. The rotation of the movable side plate 103 relative to the mold base 101 is restricted by the first end head plate 201 that can be inserted into the insertion slot 102. The armrest rods 202 facilitate the user to insert and remove the first end head plate 201.

[0030] In this embodiment: The movable end head assembly 3 includes a blocking member that can block one end of the mold body 1, a limiting member that can improve the stability of the transverse movement of the blocking member, and an adjusting member that can flexibly adjust the position of the blocking member within a certain distance range and make it stay stably at the position. The blocking member includes a second end head plate 301 movably installed in the mold body 1. A lifting rod 302 is fixedly connected to the second end head plate 301. The limiting member includes guide rails 303 fixedly connected to the front and rear side surfaces of the mold body 1. A support rod 304 is movably connected to the second end head plate 301. A spring 305 is movably connected to the outer side surface of the support rod 304. A clamping block 306 is fixedly connected to one end of the support rod 304. The adjusting member includes a support 307 fixedly installed on one side of the mold body 1. An internally threaded cylinder 308 is movably connected to the support 307. A cylinder cover 309 is fixedly connected to one end of the internally threaded cylinder 308. A joint 310 is movably connected to one side of the second end head plate 301. An activity rod 311 is arranged between the internally threaded cylinder 308 and the joint 310. A rotating handle 312 is movably installed on the activity rod 311;

[0031] The movable side plate 103 is slidably connected to the second end head plate 301. The second end head plate 301 is slidably connected to the support rod 304. The guide rail 303 is slidably connected to the clamping block 306. The support 307 is rotatably connected to the internally threaded cylinder 308. The second end head plate 301 and the activity rod 311 are both rotatably connected to the joint 310. The internally threaded cylinder 308 and the activity rod 311 are threadedly connected. The cylinder cover 309 is slidably connected to the activity rod 311;

[0032] The second end head plate 301 is used to block one end of the die base 101 and the movable side plate 103 away from the first end head plate 201. The lifting rod 302 facilitates the user to lift and place the second end head plate 301. The guide rail 303, the support rod 304, and the spring 305 jointly limit the movable range of the latch 306, and make the latch 306 without external force tend to move towards the second end head plate 301, so as to limit the shaking of the second end head plate 301 through the latch 306. The lower end of the internal thread cylinder 308 is fixed by the support 307. The cylinder cover 309 prevents the movable rod 311 from accidentally slipping off the internal thread cylinder 308. The position change of one end of the movable rod 311 that can rotate relative to the internal thread cylinder 308 is stably transmitted to the second end head plate 301 through the joint 310. The movable rod 311 can be conveniently rotated relative to the internal thread cylinder 308 through the rotating handle 312, so as to adjust the length of the part of the movable rod 311 outside the barrel body of the internal thread cylinder 308.

[0033] Working principle: When this mold is installed and used for the pouring of the concrete lintel of the distribution box, according to the length of the lintel to be poured, by rotating the movable rod 311 through the rotating handle 312, the second end head plate 301 is pushed and pulled to slide horizontally relative to the die base 101 and the movable side plate 103. When the distance between the first end head plate 201 and the second end head plate 301 reaches the pouring requirement, the rotation of the rotating handle 312 can be stopped, and raw materials such as steel bars and prepared concrete are filled into the mold cavity composed of the die base 101, the movable side plate 103, the first end head plate 201, and the second end head plate 301 in sequence and vibrated;

[0034] When demoulding is required, after the first end head plate 201 is lifted out, by pulling the latch 306 outwards, the latch 306 is separated from the guide rail 303, and then the movable side plate 103 can be rotated outwards relative to the die base 101, so that the movable side plate 103 no longer contacts the solidified concrete, and then the poured lintel can be taken out. During this process, the length of the movable rod 311 outside the internal thread cylinder 308 can also be shortened by rotating the rotating handle 312 or the second end head plate 301 can be lifted directly through the lifting rod 302, so that the second end head plate 301 is separated from the concrete, so as to prevent the second end head plate 301 from affecting the smooth removal of the lintel.

[0035] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
