[0002] Refractory brick molds are important tools used in the production of refractory bricks. They are usually made of high-strength metal materials and have precise dimensions and shapes to ensure the uniformity of refractory brick specifications. The molds are reasonably designed and can be customized according to the needs of different refractory bricks. In the production process, refractory materials are injected into the molds, and after certain processing, high-quality refractory bricks can be formed.

[0003] Existing technologies, such as the utility model with publication number CN208084626U, relate to the field of refractory material preparation, specifically a mold for refractory bricks. The mold includes a brick mold cavity body, a punching head, a base plate, and a fixing ring. The base plate is located at the bottom of the brick mold cavity body, the fixing ring is fitted onto the brick mold cavity body, a core rod is provided at the lower end of the punching head, and a spring base is provided at the lower end of the base plate. A retaining strip is provided on the inner wall of the spring base. This utility model has a simple structure, compact design, and is easy to use. The brick mold cavity body and punching head enable manual pressing of refractory bricks at a fast pressing speed. The spring base and retaining strip facilitate demolding and reduce the defect rate of refractory bricks. However, during use, the mold has a limited shape, making it difficult to produce bricks of different shapes.

[0004] To address the problem of molds having a single shape and making it difficult to produce bricks of different shapes, the existing technology involves purchasing molds of different specifications and shapes. However, this increases the user's financial expenditure and leads to frequent mold replacements, which in turn increases the processing time of the equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing molds, which have a single shape and are difficult to produce bricks of different shapes, and to propose a mold for refractory bricks.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a mold for refractory bricks, comprising a mold body and a replacement device. A mold cavity is installed on the inner wall of the mold body. The replacement device is disposed on one side of the mold body and includes an insert rod fixedly connected to the mold cavity. An mounting block is fixedly connected to the lower surface of the mold body. A rotating block is rotatably connected to the surface of the mounting block. A threaded rod is fixedly connected to the surface of the rotating block. A push block is fixedly connected to the surface of the rotating block. A groove is formed on one side of the mold body. A moving rod is slidably connected to the groove on one side of the mold body. A slider is fixedly connected to the surface of the moving rod. A threaded hole is formed on the surface of the slider. The threaded rod is threadedly connected to the slider. By setting the replacement device, it is convenient to process bricks of different shapes, increasing the flexibility of the mold. It also facilitates the replacement of the mold cavity, reducing the need to replace the entire mold when the mold cavity is damaged, thus reducing mold maintenance costs and increasing the ease of use of the equipment.

[0007] Preferably, a fixing plate is fixedly connected to the surface of the slider, and the surface of the fixing plate has a hole. By setting the fixing plate, it is easy to fix the mold cavity, which increases the stability of the equipment, reduces the difficulty of operating the equipment, and increases the ease of use of the equipment.

[0008] Preferably, the insert rod is inserted into a hole on the surface of the fixing plate. There are two insert rods, which are arranged in a mirror symmetrical manner. By setting the insert rods, the fixing plate is inserted into the insert rods during use, which facilitates the positioning of the mold cavity and increases the safety of the equipment.

[0009] Preferably, the threaded rod is located on the lower surface of the mold body, and the fixed plate and the slider are combined in an "L" shape. By setting the threaded rod, the threaded rod can easily drive the slider to move during use, which increases the ease of use of the equipment and reduces the difficulty of operating the equipment.

[0010] Preferably, the lower surface of the mold body is provided with an ejection device, which includes a sliding hole. The sliding hole is located on the lower surface of the mold body, and an ejector rod is slidably connected to the inner wall of the sliding hole. By providing an ejection device, the mold cavity can be quickly removed for replacement, which increases the ease of use of the equipment and reduces the difficulty of operating the equipment.

[0011] Preferably, there are four sliding holes, which are arranged in a mirror symmetrical manner. The sliding holes correspond to the four corners of the mold cavity. By setting the sliding holes, it is convenient to cooperate with the ejector pin to eject the mold cavity, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0012] Preferably, a frame is fixedly connected to the lower surface of the ejector rod. The frame is rectangular. By setting the ejector rod, it is easier to eject the mold cavity, which increases the stability of the equipment, makes it easier to use, and reduces the difficulty of operating the equipment.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting a replacement device and an ejection device, different shaped mold cavities are placed in the mold body during use. Then, the push block is pushed, which squeezes the rotating block to rotate. The rotating block rotates while driving the threaded rod to rotate, and the threaded rod rotates while driving the slider. As the slider moves, it drives the fixed plate to engage with the insert rod, at which point the mold cavity is fixed and molding can begin. Reversing the rotation of the rotating block drives the fixed plate to disengage from the insert rod, which then squeezes the frame. The frame drives the ejector rod to insert into the sliding hole and eject the mold cavity, facilitating quick replacement. By setting this invention, it is convenient to process bricks of different shapes, increasing the flexibility of the mold. At the same time, it is convenient to replace the mold cavity, reducing the need to replace the entire mold when the mold cavity is damaged, reducing mold maintenance costs, and increasing the ease of use of the equipment.

A slider 33 is fixedly connected to the surface of the moving rod 34. A threaded hole is opened on the surface of the slider 33. The threaded rod 35 is threadedly connected to the slider 33. By setting the replacement device 3, it is convenient to process bricks of different shapes, increasing the flexibility of the mold. At the same time, it is convenient to replace the mold cavity 2, reducing the need to replace the entire mold when the mold cavity 2 is damaged, reducing the maintenance cost of the mold, and increasing the ease of use of the equipment.

[0023] Specifically, a fixing plate 31 is fixedly connected to the surface of the slider 33. The surface of the fixing plate 31 has a hole. By setting the fixing plate 31, it is easy to fix the mold cavity 2, which increases the stability of the equipment, reduces the difficulty of operating the equipment, and increases the ease of use of the equipment.

[0024] Specifically, the insert rod 32 is inserted into the hole on the surface of the fixing plate 31. There are two insert rods 32, which are arranged in a mirror symmetrical manner. By setting the insert rods 32, the fixing plate 31 is inserted into the insert rods 32 during use, which facilitates the positioning of the mold cavity 2 and increases the safety of the equipment.

[0025] Specifically, the threaded rod 35 is located on the lower surface of the mold body 1, and the fixed plate 31 and the slider 33 are combined in an "L" shape. By setting the threaded rod 35, the threaded rod 35 can easily drive the slider 33 to move during use, which increases the ease of use of the equipment and reduces the difficulty of operating the equipment.

[0026] Specifically, an ejector device 4 is provided on the lower surface of the mold body 1. The ejector device 4 includes a sliding hole 43, which is opened on the lower surface of the mold body 1. An ejector rod 42 is slidably connected to the inner wall of the sliding hole 43.

[0027] In this embodiment, by setting the ejection device 4, the mold cavity 2 can be quickly removed and replaced, which increases the ease of use of the equipment and reduces the difficulty of operating the equipment.

[0028] Specifically, there are four sliding holes 43, which are arranged in a mirror symmetrical manner, and the four corners of the sliding holes 43 correspond to the four corners of the mold cavity 2.
