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

[0038] When the core mold 10 is used in a prefabricated room integral casting mold, the process includes assembling the core mold 10, assembling the outer mold 20, closing the core mold 10 and the outer mold 20, casting and curing, and opening 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 are sequentially abutted to form a side enclosure, and along the circumference of the side enclosure, the side end faces 14A on both sides of the corner mold 120 are both planes and approximately fit with the side end faces 14A of the adjacent inner mold 130, and the bottom end of each corner mold 120 is respectively connected to a corresponding corner portion 111, and each inner mold 130 is respectively connected to a corresponding side edge portion 112.

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

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

[0042] Then, the core mold 10 and the outer mold 20 are molded together, which can be specifically as follows:

[0043] The assembled core mold 10 is installed into the accommodating cavity through the top opening of the self-assembled outer mold 20 to form an integrated casting mold, wherein 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 therebetween, and an annular side casting space is formed between the side enclosure formed by the corner mold 120 and the inner mold 130 of the core mold 10 and the outer mold 22 of the outer mold 20, and the bottom casting space and the side casting space are connected to form a casting cavity 30.

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

[0045] Specifically, the core mold 10 and the outer mold 20 can be connected by a hanging structure, a snap-fit ​​structure, an overlapping structure, etc., and the fixation of the relative positions can be ensured.

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

[0047] The material conveying device inputs materials such as cement, sand, etc. 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 a preset height, thereby completing the one-piece casting and forming of the prefabricated room; after the casting is completed, the one-piece casting mold filled with the material can be placed in natural conditions or specific curing conditions for material strength curing until the material strength meets the requirements.

[0048] Preferably, if 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 pouring, the output end of the material conveying pipe 600 conveys material to the bottom pouring space, and the material first fills the bottom pouring space, and then gradually rises to fill the side pouring space of a preset height.

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

[0050] Among them, Figure 7-Figure 9 As shown, the core mold 10 is opened by removing the connection between the corner mold 120, the inner mold 130 and the inner bottom mold 110, and then driving the multiple corner molds 120 to move together through the linkage unit, thereby realizing the synchronous mold opening of the multiple corner molds 120 and the prefabricated room; similarly, driving the multiple inner molds 130 to move together through the linkage unit, thereby realizing the synchronous mold opening of the multiple inner molds 130 and the prefabricated room; then taking out the core mold 10 in the opened mold state from the top opening of the prefabricated room.

[0051] Among them, the outer mold 20 is opened by removing 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 prefabricated room, thereby realizing the opening of the outer mold 20 and completing the integral casting of the prefabricated room by the integral casting mold.

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

[0053] In this embodiment, Figure 1As shown, the outer mold 20 may further include a base 40, the top surface of which is provided with a plurality of radially arranged guide rails 41, and the plurality of guide rails 41 correspond to the plurality of outer molds 22 one by one; a wheel seat is provided at the bottom of each outer mold 22, and a guide wheel 223 is rollingly connected to the bottom of the wheel seat, and the guide wheel 223 is rollingly connected to one of the guide rails 41. When the outer mold 20 is opened, after the connection between the bottom mold and the outer mold 22 and the adjacent outer mold 22 is removed, each outer mold 22 can be pushed along the corresponding guide rail 41, so as to conveniently complete the opening operation of the outer mold 20. Among them, 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, and the linkage structure includes a lifting seat and a plurality of linkage parts, wherein the plurality of linkage parts of one linkage structure are respectively connected between the lifting seat and one of the corner molds 120, and the linkage parts of the other linkage structure are respectively connected between the lifting seat and one of the inner molds 130; the linkage structure is configured as follows: the linkage parts can drive the corresponding plurality of corner molds 120 or the plurality of inner molds 130 to gather or disperse under the driving of the lifting seat to move up and down. When in use, by driving the lifting seat to move up and down, the corresponding plurality of linkage parts can drive the connected plurality of corner molds or the plurality of inner molds to gather or disperse synchronously, thereby realizing the synchronous opening and closing operation of the plurality of corner molds and the synchronous opening and closing operation of the plurality of inner molds, and correspondingly improving the processing convenience and processing efficiency of the core mold and the prefabricated room integrated casting mold for the prefabricated room.

[0055] Specifically, the linkage may include a connecting rod. In the linkage structure, the first ends of multiple connecting rods are hinged to the lifting seat and are arranged at intervals along the circumference of the lifting seat, and the multiple connecting rods extend horizontally or extend toward the same side of the up and down direction of the lifting seat; the second end of the connecting rod of one of the linkage structures is respectively hinged to one of the angle molds 120, and the extension direction of each connecting rod is parallel to the side end surfaces 14A of the hinged angle mold 120; the second end of the connecting rod of another linkage structure is respectively hinged to one of the inner molds 130.

[0056] In the linkage structure, the first ends of the plurality of connecting rods are hinged to the lifting seat and are radially arranged on the outer periphery of the lifting seat, and the second ends of the plurality of connecting rods respectively point to one of the corner molds 120 (or the inner mold 130) and are connected to the corner mold 120 (or the inner mold 130), wherein the plurality of connecting rods are horizontally extended away from the lifting seat, or the plurality of connecting rods are inclined upwardly extended away from the lifting seat, or the plurality of connecting rods are inclined downwardly extended away from the lifting seat, so that when the lifting seat moves up and down, the connecting rods can apply a force with the same trend to each corner mold 120 (or the inner mold 130).

[0057] When the linkage adopts the connecting rod form, Figure 2 As shown, the core mold 10 in the assembled state is as follows: the second end of each connecting rod of one linkage structure is respectively hinged to one of the corner molds 120, and the linkage structure is defined as a first linkage structure 200; the second end of each connecting rod of the other linkage structure is respectively hinged to one of the inner molds 130, and the linkage structure is defined as a second linkage structure 300; the first linkage structure 200 is in a first mold closing position under the restriction of each corner mold 120, and in the first mold closing position, each connecting rod of the first linkage structure 200 extends horizontally in a direction away from its lifting seat, extends obliquely upward from the lifting seat, or extends obliquely downward from the lifting seat; the second linkage structure 300 is in a second mold closing position under the restriction of each inner mold 130, and in the second mold closing position, each connecting rod of the second linkage structure 300 extends horizontally in a direction away from its lifting seat, extends obliquely upward from the lifting seat, or extends obliquely downward from the lifting seat.

[0058] Among them, Figure 7-Figure 9 As shown, the opening of the core mold 10 is as follows: the connection between the corner mold 120, the inner mold 130 and the inner bottom mold 110 is removed, and then the lifting and lowering movement 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 is horizontally extended, the lifting seat can be driven to move upward or downward. Then, as the lifting seat moves upward or downward, the connecting rod will also apply a pulling force inward along the extension direction of the connecting rod to the corner mold 120 during the process of rotating relative to the lifting seat and the corner mold 120. Since the side end surfaces 14A on both sides of the corner mold 120 are parallel to the extension direction of the connecting rod hinged thereto, the horizontal component of the pulling force It is capable of pulling the corner mold 120 toward the lifting seat until the corner mold 120 breaks away from the inner mold 130 and continues to move inward for a certain distance, thereby realizing the synchronous mold opening of multiple corner molds 120 and the prefabricated room; wherein, when the connecting rod is tilted upward and extended in a direction away from the lifting seat, the lifting seat can be driven 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 is tilted downward and extended in a direction away from the lifting seat, the lifting seat can be driven 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 opening of multiple corner molds 120 by the first linkage structure 200, the lifting and lowering movement of the lifting seat is determined according to the extension direction of each connecting rod in the second linkage structure 300, so as to pull the inner mold 130 toward the lifting seat through the connecting rod, thereby realizing the synchronous opening of multiple inner molds 130 and the prefabricated room; then, the core mold 10 in the opened mold 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 integrated casting mold of the prefabricated room, and its two linkage structures are respectively linked with the multiple corner molds 120 and the multiple inner molds 130. During the mold opening operation, the synchronous mold opening of the multiple corner molds 120 and the synchronous mold opening of the multiple inner molds 130 can be achieved by driving the lifting movement of the lifting seats of the two linkage structures. The mold opening operation is convenient and efficient, thereby greatly improving the processing convenience and efficiency of the integrated casting mold for the prefabricated room.

[0061] In this embodiment, Figure 1-Figure 3 As shown, the core mold 10 also includes a guide frame 400, which includes a connecting portion 410 and a plurality of guide arms 420 provided on the connecting portion 410 and arranged radially; the guide arms 420 are slidingly connected to the tops of the corner molds 120 and the inner molds 130 in a one-to-one correspondence, and the projections of the guide arms 420 and the corresponding connecting rods to the same horizontal plane are collinear. The number of guide arms 420 in the guide frame 400 is equal to the sum of the numbers of the corner molds 120 and the inner molds 130. The multiple guide arms 420 extend horizontally and correspond to one of the corner molds 120 or the inner molds 130 respectively. Each guide arm 420 is slidably connected to the top of the corresponding corner mold 120 or the inner mold 130; wherein, each corner mold 120 and the connecting rod hinged on the inner side thereof and the guide arm 420 slidably connected to the top thereof are a group, and the guiding direction of the guide arms 420 in the same group to the corner mold 120 is parallel to the straight line where the horizontal projection of the connecting rod is located; each inner mold 130 and the connecting rod hinged on the inner side thereof and the guide arms 420 slidably connected to the top thereof are a group, and the guiding direction of the guide arms 420 in the same group to the inner mold 130 is parallel to the straight line where the horizontal projection of the connecting rod is located.

[0062] During the opening process of the core mold 10, when the lifting and lowering movement of the lifting seat in the first linkage structure 200 causes its connecting rod to apply an inward pulling force to each corner mold 120, the horizontal component of the pulling force is consistent with the guiding direction of the guide arm 420 of the same group to the corner mold 120. Then, each corner mold 120 moves horizontally toward the lifting seat along the guiding direction under the pulling action of the connecting rod and the guiding action of the guide arm 420, so as to realize the opening of each corner mold 120 and the prefabricated room; similarly, the lifting and lowering movement of the lifting seat in the second linkage structure 300 can make each inner mold 130 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, so as to realize the opening of each inner mold 130 and the prefabricated room.

[0063] Among them, the setting of the guide frame 400, in addition to the above-mentioned ability to improve the stability of the corner mold 120 and the inner mold 130 during the mold opening operation, when the core mold 10 is assembled on the outer mold 20, the guide frame 400 can be overlapped and detachably fixed to the top of the outer mold 22, thereby realizing the mold closing of the core mold 10 and the outer mold 20 and ensuring the relative position stability of the two; in addition, the guide frame 400 realizes the connection between each corner mold 120 and the inner mold 130, which can improve the connection integrity of the corner mold 120 and the inner mold 130. After the mold opening operation, the entire core mold except the inner bottom mold 110 can be lifted out through the guide frame 400, thereby further improving the mold opening convenience of the core mold 10, and correspondingly further improving the processing convenience and processing efficiency of the prefabricated room integrated casting mold for the prefabricated room.

[0064] In this embodiment, Figure 3-Figure 5 As shown, the guide frame 400 is provided with a vertical shaft 500, and two lifting seats are arranged up and down and are both 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 the axial direction of the vertical shaft 500. During the mold opening and closing operation, in the process of driving the two lifting seats to move up and down, the vertical shaft 500 can guide the vertical lifting movement of the two lifting seats, so as to improve the stability of the lifting movement of the lifting seats and the vertical position accuracy, and accordingly ensure the linkage stability of the connecting rod to each corner mold 120 and the inner mold 130, and reduce the occurrence of the connecting rod being stuck or even stuck due to the displacement of the lifting seat.

[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 axis 500 is connected to the center position of the connecting part 410 of the guide frame 400. The lengths of the multiple connecting rods in each linkage structure are equal. When the linkage structure is assembled to the corner mold 120 or the inner mold 130, there is no restriction on the circumferential corresponding position of the connecting rod in the first linkage structure 200 and the corner mold 120, and there is no restriction on the circumferential corresponding position of the connecting rod in the second linkage structure 300 and the inner mold 130, thereby improving the assembly convenience and assembly efficiency of the linkage structure and the corner mold 120 and the inner mold 130; at the same time, during the mold opening operation, the lifting and lowering movement of the lifting seat can drive the movement speed of each corner mold 120 or each inner mold 130 toward the lifting seat through the connecting rod to be equal, thereby improving the stability and smoothness of the mold opening operation and reducing the occurrence of interference between the corner mold 120 and the inner mold 130. Similarly, there is no restriction on the circumferential position of the guide frame 400 when it is connected to the corner mold 120 and the inner mold 130, so as to further improve the convenience of assembling the core mold 10.

[0066] Specifically, 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, and the outer mold 20 is also rectangular accordingly. The two are combined to form a prefabricated room with a regular rectangular shape.

[0067] Preferably, if Figure 4 and Figure 5 As shown, when the core mold 10 is in an assembled state, each connecting rod is in a horizontally extended state. During the mold opening operation, the lifting and lowering movement 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 convenience of mold opening of the core mold 10.

[0068] In this embodiment, Figure 4 and Figure 5 As shown, there are multiple groups of connecting rods in the linkage structure, and the multiple groups of connecting rods are arranged at intervals along the vertical direction on the lifting seat. The multiple groups of connecting rods are connected to different height positions of the corner mold 120 or the inner mold 130. When opening the mold, the multiple groups of connecting rods can apply parallel pulling forces to different height positions of the corner mold 120 or the inner mold 130 under the driving of the lifting movement of the lifting seat, thereby further improving the synchronous mold opening stability of the linkage structure for the corner mold 120 and the inner mold 130; in addition, during the pouring process, the multiple groups of connecting rods are supported between the lifting seat and the corner mold 120 or the inner mold 130, and the supporting effect on the corner mold 120 or the inner mold 130 is stronger, thereby improving the stability of the corner mold 120 and the inner mold 130, reducing the displacement of the corner mold 120 or the inner mold 130 under the pressure of the pouring material, resulting in changes in the shape of the prefabricated room formed by pouring, and even causing serious leakage of materials.

[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 corresponds to a side rib surface of the side end face 14A and is coplanar with the side end face 14A; 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 corresponds to a side rib surface of the side end face 14A and is coplanar with the side end face 14A. The arrangement of the first side extension rib and the second side extension rib, on the one hand, can effectively increase the fitting area between the corner mold 120 and the inner mold 130, so as to reduce the leakage of materials from between the corner mold 120 and the inner mold 130 during the casting process, while ensuring that the corner mold 120 can move relative to the inner mold 130 along the extension direction of its side end face 14A to realize the opening and closing operation; on the other hand, the first side extension rib and the second side extension rib can support the corner mold 120 and the inner mold 130 during the casting process, so as to reduce the deformation and offset of the corner mold 120 and the inner mold 130, and accordingly further reduce the leakage of materials from between the corner mold 120 and the inner mold 130 during the casting process.

[0070] In this embodiment, Figure 4 , Figure 5 , Figure 7 and Fig. 9 As shown, the vertical shaft 500 is pivotally connected to the bottom of the guide frame 400 and includes an optical axis section 510 and a threaded section 520 along its axial direction. The optical axis 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 optical axis section. 510, and one end of the second lifting seat 310 away from the first lifting seat 210 is abutted against the stop structure; the second lifting seat 310 is provided with a vertical plug hole 311, 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 passes through the plug hole 311 to extend outward by a preset length and is provided with a limiting protrusion protruding along its radial direction, and the limiting protrusion and the second lifting seat 310 are respectively provided with a first magnet and a second magnet that can be magnetically attracted on the side facing each other.

[0071] Taking the optical axis section 510 being located above the threaded section 520 as an example, when the angle mold 120 and the inner mold 130 are connected to the inner bottom mold 110 and are 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, and the linkage arm extends upward through the socket 311 to a preset length; the top end of the linkage arm is used as 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 extend horizontally or extend upward at an angle in a direction away from the corresponding lifting seats.

[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, and the guide frame 400 limits the circumferential rotation of the first lifting seat 210 through the corner mold 120 and the first connecting rod 220. Under the 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 the limiting protrusion thereon to move downward synchronously with it. Each first connecting rod 220 correspondingly pulls each corner mold 120 toward the first lifting seat 210 to move synchronously, thereby realizing the synchronous mold opening of multiple corner molds 120; at the same time, in this process, the guide frame 400 limits the circumferential rotation of the second lifting seat 310 through the inner mold 130 and the second connecting rod 320, and 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 moves downward to the top end of the socket 311, the limiting protrusion abuts against the top end surface of the socket 311, and at the same time, the first magnet is magnetically attracted to the second magnet, and then the first lifting seat 210 drives the second lifting seat 310 to move downward synchronously with it through the linkage arm and the limiting protrusion. Accordingly, 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, thereby realizing the synchronous mold opening of multiple inner molds 130, and the corner mold 120 remains located on the inner side of the inner mold 130 to reduce interference with 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 rises and drives the linkage arm and the limiting protrusion thereon and the first magnet to rise synchronously therewith. At the same time, the magnetic attraction force of the first magnet and the second magnet pulls the second lifting seat 310 upward to rise synchronously with the first lifting seat 210. Correspondingly, the corner mold 120 and the inner mold 130 move outward at the same time; continuously, when the top end of the second lifting seat 310 abuts against the stop structure, the stop structure limits the continued rise of the second lifting seat 310, and the inner mold 130 reaches the initial position. As the first lifting seat 210 pushes the linkage arm to continue to rise, the first magnet disengages from the second magnet and maintains the synchronous rising 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] It can be seen that when the first linkage structure 200 and the second linkage structure 300 of the present embodiment are linked to the vertical shaft 500 in the above-mentioned manner, the opening and assembly of the corner mold 120 and the inner mold 130 can be achieved only by driving the rotating shaft to rotate. The structure is simple and the operation is convenient, thereby further improving the convenience and efficiency of the opening and assembly of the core mold 10, and correspondingly further improving the processing convenience and efficiency of the prefabricated room integrated casting mold for the prefabricated room.

[0076] In this embodiment, the guide frame 400 is provided with a rotating driving member, and the top end of the vertical shaft 500 is connected to the rotating driving member. When the diagonal mold 120 and the inner mold 130 are opened and assembled, the rotating driving member can be started to rotate the vertical shaft 500, thereby ensuring the stability of the vertical shaft 500 to rotate the diagonal mold 120 and the inner mold 130 and reducing the consumption of manual labor.

[0077] Specifically, the rotation driving member may be a driving motor.

[0078] In addition to the above-mentioned linkage forms of the first linkage structure 200 and the second linkage structure 300, in this embodiment, the core mold 10 can also include a vertical sleeve shaft, the sleeve shaft includes an outer shaft cylinder and a core shaft rotatably inserted in the outer shaft cylinder, one of the lifting seats is rotated on the outer shaft cylinder, and the other lifting seat is rotated on the shaft section of the core shaft extending downwardly from the sleeve shaft; the guide frame 400 is provided with a driving structure, the driving structure is connected to the outer shaft cylinder and the core shaft, and is configured to: drive the outer shaft cylinder and the core shaft to rotate respectively.

[0079] The driving structure may specifically include two rotating driving members, which are respectively connected to the outer shaft cylinder and the core shaft; the first lifting seat 210 is screwed to the core shaft, and the second lifting seat 310 is screwed to the outer shaft cylinder for exemplary introduction:

[0080] The first linkage structure 200 is located below the second linkage structure 300. When the corner mold 120 and the inner mold 130 need to be opened, the rotating drive member connected to the mandrel is first started, and the rotating drive member drives the mandrel to rotate to drive the first lifting seat 210 to move upward or downward, so as to drive each corner mold 120 to move toward the first lifting seat 210 synchronously, thereby realizing the synchronous opening of multiple corner molds 120. Subsequently, the rotating drive member connected to the outer shaft cylinder can be started, and the rotating drive member drives the outer shaft cylinder to rotate to drive the second lifting seat 310 to move upward or downward, so as to drive each inner mold 130 to move toward the second lifting seat 310 synchronously, thereby realizing the synchronous opening of multiple inner molds 130.

[0081] Similarly, when the core mold 10 needs to be assembled, the rotating drive member connected to the outer shaft cylinder can be started first, and the rotating drive member drives the second lifting seat 310 to move in the opposite direction, so as to drive each inner mold 130 to move away from the second lifting seat 310 to the initial position synchronously; continuously, the rotating drive member connected to the core shaft is started, and the rotating drive member drives the first lifting seat 210 to move in the opposite direction, so as to drive each corner mold 120 to move away from the first lifting seat 210 to the initial position synchronously, so that the corner mold 120 and the inner mold 130 are spliced ​​to form an annular side enclosure.

[0082] In this embodiment, a first annular boss 113 is provided on the top edge of the inner bottom mold 110, a second annular boss 114 is provided on the edge of the first annular boss 113, and 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 mold 130 are provided with plug-in protrusions 14B, and an annular plug-in platform 14C formed by each plug-in protrusion 14B is plugged into the annular slot 115, and the corner mold 120 and the inner mold 130 are both detachably connected to the second annular boss 114 via a connecting piece 150. During assembly, the plug-in protrusions 14B of the corner mold 120 and the inner mold 130 can be plugged 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 correspondingly improving the convenience and position accuracy of connecting the corner mold 120 and the inner mold 130 to the inner bottom mold 110; continuously, the corner mold 120 and the inner mold 130 are detachably connected to the first annular boss 113 through connecting parts 150, such as bolts and nuts.

[0083] In this embodiment, Figure 4-Figure 6 As shown, the inner bottom mold 110 includes a plurality of splicing bodies 116, the side splicing surfaces 11A of adjacent splicing bodies 116 are inclined surfaces, and the splicing bodies 116 have top extension ribs 11B extending upward from the edges of their side splicing surfaces 11A, and the rib surface of the splicing side of the top extension ribs 11B is coplanar with the side splicing surface 11A. On the one hand, the inner bottom mold 110 is in the form of a plurality of splicing bodies 116, and when the inner bottom mold 110 is opened, the single splicing bodies 116 with smaller areas can be removed from the prefabricated room in sequence, thereby improving the convenience of opening the inner bottom mold 110; on the other hand, the side splicing surfaces 11A of adjacent splicing bodies 116 are set as inclined surfaces, and the top extension ribs 11B are provided, which 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.
