[0035] This embodiment provides a core mold 10, such as Figures 2-6 As shown, the device includes a core mold body 100 and a linkage unit. The core mold body 100 includes an inner bottom mold 110. The edge of the inner bottom mold 110 includes a corner portion 111 and a side portion 112. The corner portion 111 is detachably connected to a corner mold 120, and the side portion 112 is detachably connected to an inner side mold 130. The corner mold 120 and the adjacent inner side mold 130 abut against each other on their respective side end faces 14A. The linkage unit is connected to the corner mold 120 and the inner side mold 130 and is configured to drive multiple corner molds 120 to move together or apart, and to drive multiple inner side molds 130 to move together or apart.

[0036] This embodiment also provides a prefabricated room integral casting mold, such as Figure 1 As shown, the system includes an outer mold 20 and the aforementioned core mold 10. The outer mold 20 includes an outer bottom mold 21 and a plurality of outer molds 22 surrounding the outer bottom mold 21. Among the plurality of outer molds 22, at most one outer mold 22 is a fixed outer mold, and the remaining outer molds 22 are movable outer molds. The movable outer molds are detachably connected to the outer bottom mold 21 and the adjacent outer molds 22. The core mold 10 is housed in the space enclosed by the outer mold 20, and the core mold 10 and the outer mold 20 form a casting cavity 30.

[0037] In the core mold 10 provided in this embodiment, the edge of the inner bottom mold 110 includes a plurality of corner portions 111 and a side portion 112 located between two corner portions 111. Along the circumference of the inner bottom mold 110, the corner molds 120 are corner-shaped, and their number and shape are adapted to the corner portions 111; the inner side molds 130 are arc-shaped or straight-shaped, and their number and shape are adapted to the side portions 112.

[0038] When the core mold 10 is used in the precast room integrated casting mold, it includes the assembly of the core mold 10, the assembly of the outer mold 20, the closing of the core mold 10 and the outer mold 20, casting and curing, and the opening of the core mold 10 and the outer mold 20. The assembly of the core mold 10 can be as follows:

[0039] Initially, the linkage unit drives each corner mold 120 and each inner mold 130 to move in a dispersed manner, so that the corner mold 120 and the inner mold 130 abut against each other in sequence to form a side enclosure. Along the circumference of the side enclosure, the side end faces 14A on both sides of the corner mold 120 are flat and approximately fit with the side end faces 14A of the adjacent inner mold 130. The bottom end of each corner mold 120 is connected to a corresponding corner 111, and each inner mold 130 is connected to a corresponding side edge 112.

[0040] The outer mold 20 can be assembled as follows:

[0041] Each movable outer mold is detachably fixed to the corresponding edge segment of the outer bottom mold 21, and adjacent outer molds 22 are detachably fixed to each other, thereby forming a receiving cavity with a top opening.

[0042] Then, the core mold 10 and the outer mold 20 are joined together, as follows:

[0043] The assembled core mold 10 is inserted into the accommodating cavity through the top opening of the assembled outer mold 20 to form an integral casting mold. The top of the core mold 10 can be lower than, equal to, or higher than the outer mold 22. The inner bottom mold 110 of the core mold 10 is higher than the outer bottom mold 21 of the outer mold 20, and a bottom casting space is formed between the two. The side enclosure formed by the corner mold 120 and the inner side mold 130 of the core mold 10 and the outer side mold 22 of the outer mold 20 form an annular side casting space. The bottom casting space and the side casting space are connected to form the casting cavity 30.

[0044] Among them, such as Figure 1 and Figure 2 As shown, one of the inner molds 130 of the core mold 10 may have a first opening 131, and the outer mold 22 of the outer mold 20 may have a second opening 221 corresponding to the first opening 131. The outer wall of the inner mold 130 may have an annular platform 222 surrounding the first opening 131, or the inner wall of the outer mold 22 may have an annular platform 222 surrounding the second opening 221. When the core mold 10 is assembled onto the outer mold 20, the first opening 131 corresponds to the second opening 221, and the annular platform 222 surrounds the first opening 131 and the second opening 221. The outer wall of the inner mold 130 or the inner wall of the outer mold 22 may be provided with pre-assembled components such as reinforcing bars and pipes as needed.

[0045] Specifically, the core mold 10 and the outer mold 20 can be connected through a suspension structure, a snap-fit ​​structure, an overlapping structure, etc., to ensure that their relative positions are fixed.

[0046] Then the pouring and curing operations can be carried out:

[0047] The material conveying device feeds cement, sand and other materials into the casting cavity 30 through its material conveying pipe 600 until the materials fill the bottom casting space and the side casting space of the preset height, thereby completing the integral casting and molding of the precast room. After casting, the integral casting mold containing the materials can be placed under natural conditions or specific curing conditions to cure the strength of the materials until the strength of the materials reaches the requirements.

[0048] Better, such as Figure 1 and Figure 2 As shown, the conveying end of the material conveying pipe 600 can extend into the core mold 10 through the first opening 131 and the second opening 221, and pass downward through the inner bottom mold 110; during casting, the output end of the material conveying pipe 600 conveys material to the bottom casting space, and the material first fills the bottom casting space, and then gradually rises to fill the side casting space of the preset height.

[0049] Then, the core mold 10 and the outer mold 20 can be opened:

[0050] Among them, such as Figures 7-9 As shown, the core mold 10 is opened by: disconnecting the corner molds 120, inner molds 130 and inner bottom molds 110, and then driving multiple corner molds 120 to converge through a linkage unit, thereby achieving synchronous opening of multiple corner molds 120 and the prefabricated room; similarly, driving multiple inner molds 130 to converge through a linkage unit, thereby achieving synchronous opening of multiple inner molds 130 and the prefabricated room; then the core mold 10 in the opened state is taken out from the top opening of the prefabricated room.

[0051] Among them, the opening of the outer mold 20 is achieved by dismantling the connection between each movable outer mold and the adjacent outer mold 22 and the connection with the outer bottom mold 21, and pulling each movable outer mold outward from the precast room, thereby realizing the opening of the outer mold 20 and completing the integral casting of the precast room by the integral casting mold.

[0052] The core mold 10 provided in this embodiment is applied to the precast room integrated casting mold. Its linkage unit is linked with multiple corner molds 120 and multiple inner molds 130. In the mold opening operation, the linkage unit can realize the synchronous mold opening of multiple corner molds 120 and multiple inner molds 130. The mold opening operation is convenient and efficient, thereby greatly improving the processing convenience and processing efficiency of the precast room integrated casting mold for precast rooms.

[0053] In this embodiment, as Figure 1As shown, the outer mold 20 may further include a base 40. The top surface of the base 40 is provided with multiple sets of radially arranged guide rails 41, and each set of guide rails 41 corresponds one-to-one with multiple outer molds 22. Each outer mold 22 has a wheel seat at its bottom, and a guide wheel 223 is rotatably connected to the bottom of the wheel seat. The guide wheel 223 is rotatably connected to one of the sets of guide rails 41. When performing the mold opening operation on the outer mold 20, after removing the connection between the bottom mold and the outer molds 22 and adjacent outer molds 22, each outer mold 22 can be pushed along the corresponding guide rail 41, thereby conveniently completing the mold opening operation of the outer mold 20. A support rib 224 may also be connected between the wheel seat and the corresponding outer mold 22 to improve the strength of the outer mold 22 and reduce the deformation of the outer mold 22 during the casting process.

[0054] In this embodiment, the linkage unit includes two linkage structures, each comprising a lifting seat and multiple linkage components. The linkage components of one linkage structure are connected between the lifting seat and one of the corner molds 120, while the linkage components of the other linkage structure are connected between the lifting seat and one of the inner molds 130. The linkage structures are configured such that, driven by the lifting seat's lifting motion, the linkage components can cause the corresponding multiple corner molds 120 or multiple inner molds 130 to converge or disperse. In use, by driving the lifting seat to rise and fall, the corresponding multiple linkage components can drive the connected multiple corner molds or multiple inner molds to converge or disperse synchronously, thereby achieving synchronous opening and closing operations of multiple corner molds and multiple inner molds. This correspondingly improves the processing convenience and efficiency of the core mold and precast room integrated casting mold for precast rooms.

[0055] Specifically, the linkage may include connecting rods. In the linkage structure, the first ends of multiple connecting rods are all hinged to the lifting seat and arranged at intervals along the circumference of the lifting seat. The multiple connecting rods extend horizontally or extend to the same side in the vertical direction of the lifting seat. The second ends of the connecting rods in one linkage structure are respectively hinged to one of the corner molds 120, and the extension direction of each connecting rod is parallel to the two side end faces 14A of the hinged corner molds 120. The second ends of the connecting rods in another linkage structure are respectively hinged to one of the inner molds 130.

[0056] In the linkage structure, the first ends of multiple connecting rods are all hinged to the lifting seat and arranged radially on the outer periphery of the lifting seat. The second ends of multiple connecting rods point to one of the corner molds 120 (or inner mold 130) and are connected to the corner mold 120 (or inner mold 130). The multiple connecting rods extend horizontally away from the lifting seat, or extend upwardly away from the lifting seat, or extend downwardly away from the lifting seat, so that when the lifting seat moves up and down, it can apply the same force to each corner mold 120 (or inner mold 130) through the connecting rods.

[0057] When the linkage is in the form of a link, such as Figure 2 As shown, the assembled core mold 10 is as follows: the second ends of each link of one linkage structure are respectively hinged to one corner mold 120, and this linkage structure is defined as the first linkage structure 200; the second ends of each link of the other linkage structure are respectively hinged to one inner mold 130, and this linkage structure is defined as the second linkage structure 300; the first linkage structure 200 is in the first mold-closing position under the restriction of each corner mold 120, and in the first mold-closing position, each link of the first linkage structure 200 extends horizontally, tilts upward towards the lifting seat, or tilts downward towards the lifting seat in the direction away from its lifting seat; the second linkage structure 300 is in the second mold-closing position under the restriction of each inner mold 130, and in the second mold-closing position, each link of the second linkage structure 300 extends horizontally, tilts upward towards the lifting seat, or tilts downward towards the lifting seat in the direction away from its lifting seat.

[0058] Among them, such as Figures 7-9 As shown, the core mold 10 is opened as follows: the connection between the corner mold 120, the inner mold 130 and the inner bottom mold 110 is removed. Then, the lifting motion of the lifting seat is determined according to the extension direction of each connecting rod in the first linkage structure 200. Specifically, when the connecting rod extends horizontally, it can drive the lifting seat to move upward or downward. As the lifting seat moves upward or downward, the connecting rod will also apply an inward pulling force along the extension direction of the connecting rod to the corner mold 120 during the rotation relative to the lifting seat and the corner mold 120. Since the side end faces 14A on both sides of the corner mold 120 are parallel to the extension direction of the connecting rod hinged to them, the horizontal component of this pulling force is... It can pull the corner mold 120 toward the lifting seat until the corner mold 120 disengages from the inner mold 130 and continues to move inward a certain distance, thereby realizing the synchronous mold opening of multiple corner molds 120 and the prefabricated room; wherein, when the connecting rod extends upward in the direction away from the lifting seat, it can drive the lifting seat to move downward, so as to pull the corner mold 120 toward the lifting seat through the connecting rod, thereby realizing the synchronous mold opening of multiple corner molds 120 and the prefabricated room; when the connecting rod extends downward in the direction away from the lifting seat, it can drive the lifting seat to move upward, so as to pull the corner mold 120 toward the lifting seat through the connecting rod, thereby realizing the synchronous mold opening of multiple corner molds 120 and the prefabricated room.

[0059] Continuing, similar to the synchronous mold opening of multiple corner molds 120 in the first linkage structure 200, the lifting motion of the lifting seat is determined according to the extension direction of each link in the second linkage structure 300, so as to pull the inner mold 130 toward the lifting seat through the link, thereby realizing the synchronous mold opening of multiple inner molds 130 and the prefabricated room; then the core mold 10 in the mold opening state is taken out from the top opening of the prefabricated room.

[0060] The core mold 10 provided in this embodiment is applied to the precast room integrated casting mold. Its two linkage structures are respectively linked with multiple corner molds 120 and multiple inner molds 130. In the mold opening operation, the simultaneous opening of multiple corner molds 120 and multiple inner molds 130 can be achieved by driving the lifting movement of the lifting seat of the two linkage structures. The mold opening operation is convenient and efficient, thereby greatly improving the processing convenience and processing efficiency of the precast room integrated casting mold for precast rooms.

[0061] In this embodiment, as Figures 1-3 As shown, the core mold 10 also includes a guide frame 400, which includes a connecting part 410 and a plurality of guide arms 420 arranged radially on the connecting part 410; the guide arms 420 are slidably connected to the top of the corner mold 120 and the inner mold 130 respectively, and the guide arms 420 and the corresponding connecting rods are collinear in their projection onto the same horizontal plane. The number of guide arms 420 in the guide frame 400 is equal to the sum of the number of corner molds 120 and inner molds 130. The multiple guide arms 420 extend horizontally and correspond to one of the corner molds 120 or inner molds 130 respectively. Each guide arm 420 is slidably connected to the top of the corresponding corner mold 120 or inner mold 130. Each corner mold 120, together with the connecting rod hinged to its inner side and the guide arm 420 slidably connected to its top, forms a group. The guiding direction of the guide arms 420 in the same group is parallel to the horizontal projection line of the connecting rod. Each inner mold 130, together with the connecting rod hinged to its inner side and the guide arm 420 slidably connected to its top, forms a group. The guiding direction of the guide arms 420 in the same group is parallel to the horizontal projection line of the connecting rod.

[0062] During the mold opening process of the core mold 10, when the lifting motion of the lifting seat in the first linkage structure 200 causes its connecting rod to exert an inward pulling force on each corner mold 120, the horizontal component of this pulling force is consistent with the guiding direction of the guide arm 420 of the same group on the corner mold 120. Then, under the pulling action of the connecting rod and the guiding action of the guide arm 420, each corner mold 120 moves horizontally toward the lifting seat along the guiding direction to realize the mold opening of each corner mold 120 and the prefabricated room. Similarly, the lifting motion of the lifting seat in the second linkage structure 300 enables each inner mold 130 to move toward the lifting group along the guiding direction under the pulling action of the corresponding connecting rod and the guiding action of the corresponding guide arm 420 to realize the mold opening of each inner mold 130 and the prefabricated room.

[0063] In addition to improving the stability of the corner mold 120 and inner mold 130 during mold opening operations, the guide frame 400 can overlap and detachably fix the core mold 10 to the top of the outer mold 22 when it is assembled with the outer mold 20, thereby realizing the mold closing of the core mold 10 and the outer mold 20 and ensuring the relative positional stability of the two. Furthermore, the guide frame 400 connects the corner mold 120 and the inner mold 130, which can improve the overall connection between the corner mold 120 and the inner mold 130. After the mold opening operation, the entire core mold except for the inner bottom mold 110 can be lifted out through the guide frame 400, thereby further improving the ease of mold opening of the core mold 10 and correspondingly improving the processing convenience and efficiency of the precast room integrated casting mold for precast rooms.

[0064] In this embodiment, as Figures 3-5 As shown, the guide frame 400 is equipped with a vertical shaft 500, and two lifting seats are arranged vertically and both are sleeved on the vertical shaft 500. The lifting seats are configured to be able to move up and down relative to the vertical shaft 500 along its axial direction. During the mold opening and closing operation, when driving the two lifting seats to move up and down, the vertical shaft 500 can guide the vertical movement of the two lifting seats to improve the stability of the lifting movement and the accuracy of the vertical position. This ensures the linkage stability of the connecting rod with each corner mold 120 and the inner mold 130, and reduces the occurrence of connecting rod jamming or even seizing due to lifting seat offset.

[0065] Specifically, multiple corner molds 120 are arranged in a circular array, and correspondingly, multiple inner molds 130 are also arranged in a circular array. Multiple connecting rods of the linkage structure are evenly spaced along the circumference of the lifting seat. Multiple guide arms 420 in the guide frame 400 are evenly spaced along the circumference of the connecting part 410, and the vertical shaft 500 is connected to the center position of the connecting part 410 of the guide frame 400. In each linkage structure, the lengths of the multiple connecting rods are all equal. When assembling the linkage structure onto the corner mold 120 or the inner mold 130, there are no restrictions on the circumferential corresponding positions of the connecting rods in the first linkage structure 200 and the corner mold 120, and similarly, there are no restrictions on the circumferential corresponding positions of the connecting rods in the second linkage structure 300 and the inner mold 130. This improves the ease and efficiency of assembling the linkage structure with the corner mold 120 and the inner mold 130. Furthermore, during mold opening, the lifting motion of the lifting seat can drive each corner mold 120 or each inner mold 130 to move towards the lifting seat at equal speeds via the connecting rods, thereby improving the stability and smoothness of the mold opening operation and reducing interference between the corner mold 120 and the inner mold 130. Similarly, the circumferential position of the guide frame 400 connected to the corner mold 120 and the inner mold 130 is also unrestricted, further improving the ease of assembling the core mold 10.

[0066] Specifically, such as Figure 2As shown, there can be four corner molds 120 and four inner molds 130. The four corner molds 120 and the four inner molds 130 form a rectangular side enclosure. The outer mold 20 is also rectangular. The two are combined to form a prefabricated room with a regular rectangular shape.

[0067] Better, such as Figure 4 and Figure 5 As shown, when the core mold 10 is in the assembled state, all connecting rods are in a horizontally extended state. Therefore, during the mold opening operation, the lifting direction of the lifting seat is not restricted. Driving the lifting seat to move upward or downward can realize the opening of the corner mold 120 or the inner mold 130, thereby improving the mold opening convenience of the core mold 10.

[0068] In this embodiment, as Figure 4 and Figure 5 As shown, the linkage structure consists of multiple sets of connecting rods, which are arranged vertically at intervals on the lifting seat. These multiple sets of connecting rods are connected to different height positions of the corner mold 120 or the inner mold 130. During mold opening, the multiple sets of connecting rods, driven by the lifting motion of the lifting seat, apply parallel pulling forces to different height positions of the corner mold 120 or the inner mold 130, thereby further improving the stability of the linkage structure for the synchronous mold opening of the corner mold 120 and the inner mold 130. Furthermore, during the casting process, the multiple sets of connecting rods support the lifting seat and the corner mold 120 or the inner mold 130, providing stronger support for the corner mold 120 or the inner mold 130, thus improving the stability of the corner mold 120 and the inner mold 130 and reducing the risk of displacement of the corner mold 120 or the inner mold 130 under the pressure of the cast material, which could lead to changes in the shape of the precast room formed by the casting, or even, in severe cases, internal leakage of the material.

[0069] In this embodiment, the corner mold 120 has a first side extension rib extending inward at the edge of its side end face 14A, and the first side extension rib is coplanar with the side end face 14A on one side rib surface; the inner mold 130 has a second side extension rib extending inward at the edge of its side end face 14A, and the second side extension rib is coplanar with the side end face 14A on one side rib surface. The first and second side extension ribs serve two purposes. First, while ensuring that the corner mold 120 can move relative to the inner mold 130 along its side end face 14A to achieve mold opening and closing operations, they effectively increase the contact area between the corner mold 120 and the inner mold 130, thereby reducing material leakage between the corner mold 120 and the inner mold 130 during casting. Second, the first and second side extension ribs provide support for the corner mold 120 and the inner mold 130 during casting, reducing deformation and displacement of the corner mold 120 and the inner mold 130, and further reducing material leakage between the corner mold 120 and the inner mold 130 during casting.

[0070] In this embodiment, as Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the vertical shaft 500 is pivotally connected to the bottom of the guide frame 400 and includes a smooth shaft section 510 and a threaded section 520 along its axial direction. The smooth shaft section 510 is provided with a stop structure (not shown in the figure). The lifting seat of the first linkage structure 200 is the first lifting seat 210 and the connecting rod is the first connecting rod 220. The lifting seat of the second linkage structure 300 is the second lifting seat 310 and the connecting rod is the second connecting rod 320. The first lifting seat 210 is screwed to the threaded section 520, and the second lifting seat 310 is slidably sleeved on the smooth shaft section. 510, and the end of the second lifting seat 310 facing away from the first lifting seat 210 abuts against the stop structure; the second lifting seat 310 is provided with a vertical insertion hole 311, and the core mold 10 also includes a linkage arm (not shown in the figure), the first end of the linkage arm is connected to the first lifting seat 210, the second end of the linkage arm extends outward through the insertion hole 311 for a preset length and is provided with a limiting protrusion protruding along its radial direction, and the limiting protrusion and the side of the second lifting seat 310 facing each other are respectively provided with a first magnet and a second magnet that can be magnetically attracted.

[0071] Taking the optical axis segment 510 located above the threaded segment 520 as an example, when the corner mold 120 and the inner mold 130 are connected to the inner bottom mold 110 in an assembled state, the first linkage structure 200 is located below the second linkage structure 300, the second lifting seat 310 is located below the stop structure and abuts against the stop structure, the bottom end of the linkage arm is connected to the first lifting seat 210 as its first end, the linkage arm extends upward through the insertion hole 311 and extends upward to a predetermined length; the top end of the linkage arm is its second end, the limiting protrusion is located at the top end of the linkage arm and protrudes radially from the side of the linkage arm; the connecting rods of the first linkage structure 200 and the second linkage structure 300 both extend horizontally or tilt upward in the direction away from the corresponding lifting seat.

[0072] When it is necessary to open the corner mold 120 and the inner mold 130, the vertical shaft 500 is driven to rotate in the first direction. The guide frame 400 restricts the circumferential rotation of the first lifting seat 210 through the corner mold 120 and the first connecting rod 220. Under the action of this circumferential restriction and the threaded connection of the threaded section 520, the first lifting seat 210 moves downward along the threaded rod and pulls the linkage arm and its limiting protrusion to move downward synchronously. Each first connecting rod 220 pulls each corner mold 120 to move synchronously toward the first lifting seat 210, thereby realizing the synchronous opening of multiple corner molds 120. At the same time, during this process, the guide frame 400 restricts the circumferential rotation of the second lifting seat 310 through the inner mold 130 and the second connecting rod 320. The vertical shaft 500 rotates relative to the second lifting seat 310, and the height of the second lifting seat 310 remains unchanged.

[0073] Continuing, when the limiting protrusion descends and reaches the top of the insertion hole 311, the limiting protrusion abuts against the top surface of the insertion hole 311. At the same time, the first magnet is attracted to the second magnet. Subsequently, the first lifting seat 210 drives the second lifting seat 310 to move downward synchronously through the linkage arm and the limiting protrusion. Correspondingly, the corner mold 120 continues to move toward the first lifting seat 210 under the pulling action of the first connecting rod 220 and the guiding action of the guide arm 420. At the same time, the inner mold 130 continues to move toward the second lifting seat 310 under the pulling action of the second connecting rod 320 and the guiding action of the guide arm 420. This achieves synchronous mold opening of multiple inner molds 130, and the corner mold 120 remains inside the inner mold 130 to reduce interference to the movement of the inner mold 130.

[0074] Similarly, when the core mold 10 needs to be assembled, the vertical shaft 500 can be driven to rotate in the second direction. The first lifting seat 210 moves upward and drives the linkage arm and its limiting protrusion and the first magnet to move upward synchronously. At the same time, the magnetic attraction force of the first magnet and the second magnet pulls the second lifting seat 310 upward synchronously with the first lifting seat 210. Correspondingly, the corner mold 120 and the inner mold 130 move outward at the same time. Continuing, when the top of the second lifting seat 310 abuts against the stop structure, the stop structure restricts the second lifting seat 310 from continuing to rise. The inner mold 130 reaches the initial position, and as the first lifting seat 210 pushes the linkage arm to continue to rise, the first magnet disengages from the second magnet and maintains synchronous upward movement with the first lifting seat 210 until the first lifting seat 210 rises to the initial position. At this time, the corner mold 120 reaches the initial position and cooperates with the inner mold 130 to form a ring-shaped side enclosure again.

[0075] As can be seen, when the first linkage structure 200 and the second linkage structure 300 of this embodiment are linked to the vertical shaft 500 in the above manner, the opening and assembly of the corner mold 120 and the inner mold 130 can be realized simply by driving the rotating shaft to rotate. The structure is simple and the operation is convenient, thereby further improving the ease and efficiency of opening and assembling the core mold 10, and correspondingly further improving the processing convenience and processing efficiency of the precast room integrated casting mold for precast rooms.

[0076] In this embodiment, the guide frame 400 is equipped with a rotation drive, and the top end of the vertical shaft 500 is connected to the rotation drive. When the diagonal mold 120 and the inner mold 130 are being opened and assembled, the rotation drive can be activated to rotate the vertical shaft 500, thereby ensuring the stability of the rotation of the vertical shaft 500 on the diagonal mold 120 and the inner mold 130, and reducing the consumption of manual labor.

[0077] Specifically, the rotation drive can be a drive motor.

[0078] In addition to the above-mentioned linkage forms, in this embodiment, the first linkage structure 200 and the second linkage structure 300 may also include a vertical sleeve shaft, which includes an outer shaft cylinder and a mandrel rotatably inserted into the outer shaft cylinder. One lifting seat is screwed to the outer shaft cylinder, and the other lifting seat is screwed to the shaft segment of the mandrel extending downward from the sleeve shaft. The guide frame 400 is provided with a drive structure, which is connected to the outer shaft cylinder and the mandrel and is configured to drive the outer shaft cylinder and the mandrel to rotate respectively.

[0079] The drive structure may specifically include two rotary drive components, which are respectively connected to the outer shaft cylinder and the spindle; exemplified by a first lifting seat 210 screwed onto the spindle and a second lifting seat 310 screwed onto the outer shaft cylinder:

[0080] The first linkage structure 200 is located below the second linkage structure 300. When the corner molds 120 and inner molds 130 need to be opened, the rotation drive connected to the mandrel is first activated. This rotation drive drives the mandrel to rotate, thereby driving the first lifting seat 210 to move upward or downward, so that each corner mold 120 moves synchronously toward the first lifting seat 210, thus achieving synchronous opening of multiple corner molds 120. Continuing, the rotation drive connected to the outer shaft cylinder can be activated. This rotation drive drives the outer shaft cylinder to rotate, thereby driving the second lifting seat 310 to move upward or downward, so that each inner mold 130 moves synchronously toward the second lifting seat 310, thus achieving synchronous opening of multiple inner molds 130.

[0081] Similarly, when the core mold 10 needs to be assembled, the rotation drive connected to the outer shaft cylinder can be activated first. The rotation drive drives the second lifting seat 310 to move in the opposite direction, so that each inner mold 130 moves synchronously away from the second lifting seat 310 to the initial position. Then, the rotation drive connected to the mandrel is activated. The rotation drive drives the first lifting seat 210 to move in the opposite direction, so that each corner mold 120 moves synchronously away from the first lifting seat 210 to the initial position, so that the corner mold 120 and the inner mold 130 are spliced ​​together to form a ring-shaped side enclosure.

[0082] In this embodiment, the top edge of the inner bottom mold 110 is surrounded by a first annular boss 113, and the edge of the first annular boss 113 is surrounded by a second annular boss 114. The second annular boss 114 and the first annular boss 113 form an annular slot 115. The bottom ends of the corner mold 120 and the inner side mold 130 are provided with insertion protrusions 14B. The annular insertion platform 14C formed by each insertion protrusion 14B is inserted into the annular slot 115. The corner mold 120 and the inner side mold 130 are detachably connected to the second annular boss 114 through the connector 150. During assembly, the insertion protrusions 14B of the corner mold 120 and the inner mold 130 can be inserted into the annular slot 115 to locate the connection position of the corner mold 120 and the inner mold 130 with the inner bottom mold 110, thereby improving the convenience and positional accuracy of connecting the corner mold 120 and the inner mold 130 to the inner bottom mold 110; furthermore, the corner mold 120 and the inner mold 130 are detachably connected to the first annular boss 113 by means of connectors 150, such as bolts and nuts.

[0083] In this embodiment, as Figures 4-6 As shown, the inner bottom mold 110 includes multiple splicing bodies 116. The side splicing surfaces 11A of adjacent splicing bodies 116 are inclined surfaces. A top extension rib 11B extends upward from the edge of the side splicing surface 11A of each splicing body 116, and the rib surface of the splicing side of the top extension rib 11B is coplanar with the side splicing surface 11A. On the one hand, the inner bottom mold 110 adopts the form of multiple splicing bodies 116. When opening the inner bottom mold 110, individual splicing bodies 116 with smaller areas can be disassembled from the prefabricated room in sequence, thereby improving the ease of opening the inner bottom mold 110. On the other hand, setting the side splicing surfaces 11A of adjacent splicing bodies 116 to be inclined surfaces and providing top extension ribs 11B can double increase the splicing area of ​​adjacent splicing bodies 116, so as to effectively reduce the occurrence of material leakage from the splicing area during the pouring process.
