[0082] As shown in Figure 3 the outer mold B of the mold in the prefabricated room production line can include an outer bottom mold 710 and a plurality of outer side molds 720 surrounding the outer bottom mold 710, among the plurality of outer side molds 720, at most one outer side mold 720 is a fixed outer side mold 720, and the rest of the outer side molds 720 are movable outer side molds 720, and the movable outer side molds 720 are detachably connected with the outer bottom mold 710 and the adjacent outer side molds 720; the core mold A is contained in the space surrounded by the outer mold B, and a pouring cavity 800 is formed between the core mold A and the outer mold B.

[0083] The core mold A provided by the embodiment includes Figure 6 as shown, the edge of the inner bottom mold 110 includes a plurality of corner portions 111 and a side edge portion 112 between two corner portions 111, along the circumference of the inner bottom mold 110, the corner mold 120 is a corner shape, and the number and shape thereof are adapted to the corner portion 111; the inner side mold 130 is arc-shaped or linear, and the number and shape thereof are adapted to the side edge portion 112. The linkage unit includes two linkage structures, and in the linkage structure, the first end of each of the plurality of connecting rods is hingedly connected to the lifting seat, and is arranged radially outward of the lifting seat, the second end of each of the plurality of connecting rods points to one of the corner molds 120 (or the inner side molds 130) and is connected to the corner mold 120 (or the inner side mold 130), wherein each of the plurality of connecting rods extends horizontally away from the lifting seat, or each of the plurality of connecting rods extends upwardly and obliquely away from the lifting seat, or each of the plurality of connecting rods extends downwardly and obliquely away from the lifting seat, so that the lifting seat can exert the same trend of force on each corner mold 120 (or inner side mold 130) when the lifting seat moves up and down.

[0084] The core mold A is applied to the mold of the prefabricated room production line, and in the production process, when the formed piece E reaches the mold opening station 41 for mold opening processing, the second end of each connecting rod of one linkage structure in the core mold A is hingedly connected to one corner mold 120, and the linkage structure is defined as the first linkage structure 200; the second end of each connecting rod of the other linkage structure is hingedly connected to one inner side mold 130, and the linkage structure is defined as the second linkage structure 300.

Specifically, when the connecting rod is horizontally extended, the lifting seat can be driven to move upward or downward, and then with the lifting movement of the lifting seat, the connecting rod will also exert a pulling force along the extension direction of the connecting rod on the corner mold 120 in the process of rotating relative to the lifting seat and the corner mold 120. Since the side end surface 14a on both sides of the corner mold 120 is parallel to the extension direction of the connecting rod hinged thereto, the horizontal component of the pulling force can pull the corner mold 120 towards the lifting seat until the corner mold 120 is separated from the inner side mold 130 and continues to move inward a certain distance, thereby realizing the synchronous mold opening of the plurality of corner molds 120 and the room base body F. Wherein, when the connecting rod extends upwardly away from the lifting seat, the lifting seat can be driven to move downward to pull the corner mold 120 towards the lifting seat by the connecting rod, thereby realizing the synchronous mold opening of the plurality of corner molds 120 and the room base body F; when the connecting rod extends downwardly away from the lifting seat, the lifting seat can be driven to move upward to pull the corner mold 120 towards the lifting seat by the connecting rod, thereby realizing the synchronous mold opening of the plurality of corner molds 120 and the room base body F.

[0086] Continuously, similar to the synchronous mold opening of the plurality of corner molds 120 by the first linkage structure 200, the lifting movement of the lifting seat thereof is determined according to the extension direction of each connecting rod in the second linkage structure 300 to pull the inner side mold 130 towards the lifting seat by the connecting rod, thereby realizing the synchronous mold opening of the plurality of inner side molds 130 and the room base body F; then the core mold A in the mold opening state is taken out from the top opening of the room base body F; wherein the inner bottom mold 110 is sent to the conveying area 31b of the first curing bin 31, and the other components of the core mold A are sent to the upper conveying layer 71.

[0087] Assembly of the core mold A: when the inner bottom mold 110 and other components of the core mold A are all transported to the core mold pretreatment station 81a, the bottom end of each corner mold 120 is connected to the corresponding corner 111, and each inner side mold 130 is connected to the corresponding side edge 112, at this time, the corner mold 120 and the inner side mold 130 jointly form the annular side wall 14b, and the side end face 14a on both sides of the corner mold 120 along the circumference of the side wall 14b is a plane and is approximately fitted between the side end face 14a of the adjacent inner side mold 130; the first linkage structure 200 is in the first mold closing position under the restriction of each corner mold 120, and at this first mold closing position, each connecting rod of the first linkage structure 200 extends horizontally away from the lifting seat, inclines upward or downward relative to the lifting seat; the second linkage structure 300 is in the second mold closing position under the restriction of each inner side mold 130, and at this second mold closing position, each connecting rod of the second linkage structure 300 extends horizontally away from the lifting seat, inclines upward or downward relative to the lifting seat.

[0088] Opening of the outer mold B: at the opening station 41, the connection between each movable outer side mold 720 and the adjacent outer side mold 720 and the outer bottom mold 710 is removed, and each movable outer side mold 720 is pulled outward to separate from the room base F, thereby realizing the opening of the outer mold B, and the outer mold B is sent to the lower conveying layer 72.

[0089] Assembly of the outer mold B: when the outer mold B in the opened state is transported to the outer mold pretreatment station 82a, each movable outer side mold 720 is detachably fixed to the corresponding edge section of the outer bottom mold 710, and the adjacent outer side molds 720 are detachably fixed, thereby forming a top-open accommodating cavity.

[0090] Subsequently, the core mold A in the mold closing state and the outer mold B in the mold closing state are transported to the mold closing station 11, and the mold closing process of the core mold A and the outer mold B can be specifically as follows:

[0091] The core mold A in the mold closing state is loaded into the accommodating cavity of the outer mold B in the mold closing state to form an integrated pouring mold C, wherein the top of the core mold A can be lower than, equal to, or higher than the outer side mold 720, the inner bottom mold 110 of the core mold A is higher than the outer bottom mold 710 of the outer mold B and forms a bottom pouring space therebetween, the side wall 14b surrounded by the corner mold 120 and the inner side mold 130 of the core mold A and the outer side mold 720 of the outer mold B form an annular side pouring space, and the bottom pouring space and the side pouring space are communicated to form a pouring cavity 800.

[0092] The inner side mold 130 of the core mold A can be provided with a first opening 131, and the outer side mold 720 of the outer mold B is provided with a second opening 721 corresponding to the first opening 131. The outer wall of the inner side mold 130 is provided with an annular surrounding platform 722 surrounding the first opening 131, or the inner wall of the outer side mold 720 is provided with an annular surrounding platform 722 surrounding the second opening 721. When the core mold A is assembled with the outer mold B, the first opening 131 corresponds to the second opening 721, and the annular surrounding platform 722 surrounds between the first opening 131 and the second opening 721. The outer wall of the inner side mold 130 or the inner wall of the outer side mold 720 can be provided with reinforcing steel bars, pipelines and other pretreatment components as needed.

[0093] Specifically, the core mold A and the outer mold B can be connected by a hanging structure, a buckle structure, a lap joint structure and the like, and the relative position is fixed.

[0094] The pouring device 20 can input cement concrete and other materials into the pouring cavity 800 through the material conveying pipe 21 until the materials fill the bottom pouring space and the side pouring space of the preset height, thereby completing the integrated pouring and forming of the room base F. Specifically, as shown in Figure 4 and Figure 6 The conveying end of the material conveying pipe 21 can extend into the core mold A through the first opening 131 and the second opening 721, and pass through the inner bottom mold 110 downward. During pouring, the output end of the material conveying pipe 21 conveys materials to the bottom pouring space. The materials first fill the bottom pouring space, and then gradually fill the side pouring space of the preset height.

[0095] The core mold A provided in the embodiment is applied to a prefabricated room production line, and the two linkage structures are respectively linked with the plurality of corner molds 120 and the plurality of inner side molds 130. In the mold opening operation, the synchronous mold opening of the plurality of corner molds 120 and the synchronous mold opening of the plurality of inner side molds 130 can be realized 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 prefabricated room production line for prefabricated rooms.

[0096] In the embodiment, as shown in Figure 3As shown, the outer mold B can further include a base 730, the top surface of the base 730 is provided with a plurality of sets of radially arranged guide rails 731, and the plurality of sets of guide rails 731 correspond to the plurality of outer side molds 720 one by one; the bottom of each outer side mold 720 is provided with a wheel seat 723, the bottom of the wheel seat 723 is rollingly connected with a guide wheel 724, and the guide wheel 724 is rollingly connected with one of the guide rails 731. When the mold opening operation of the outer mold B is performed, after the bottom mold and the outer side mold 720 and the adjacent outer side mold 720 are removed, each outer side mold 720 can be pushed along the corresponding guide rail 731, so that the mold opening operation of the outer mold B is conveniently completed. Among them, the wheel seat 723 and the corresponding outer side mold 720 can be further connected with a supporting rib 740 to improve the strength of the outer side mold 720 and reduce the deformation of the outer side mold 720 during pouring.

[0097] In the embodiment, as shown in the figure, Figure 4 The core mold A further includes a guide frame 500, the guide frame 500 includes a connecting portion 510 and a plurality of guide arms 520 arranged radially on the connecting portion 510; the guide arms 520 are slidingly connected with the top of the corner mold 120 and the inner side mold 130 one by one, and the projection of the guide arm 520 and the corresponding connecting rod to the same horizontal plane is collinear. The number of guide arms 520 in the guide frame 500 is equal to the sum of the number of corner molds 120 and the number of inner side molds 130, and the plurality of guide arms 520 are horizontally extended and correspond to one of the corner molds 120 or the inner side molds 130 respectively, and each guide arm 520 is slidingly connected with the top of the corresponding corner mold 120 or the inner side mold 130; wherein each corner mold 120, the connecting rod hinged to the inner side thereof, and the guide arm 520 slidingly connected to the top thereof form a group, and the guide direction of the guide arm 520 in the same group to the corner mold 120 is parallel to the straight line where the horizontal projection of the connecting rod lies; each inner side mold 130, the connecting rod hinged to the inner side thereof, and the guide arm 520 slidingly connected to the top thereof form a group, and the guide direction of the guide arm 520 in the same group to the inner side mold 130 is parallel to the straight line where the horizontal projection of the connecting rod lies.

[0098] Then, during the mold opening process of the core mold A, when the lifting seat in the first linkage structure 200 exerts an inward pulling force on each corner mold 120 through the connecting rod, the horizontal component of the pulling force is consistent with the guide direction of the guide arm 520 in the same group to the corner mold 120, and then each corner mold 120 moves horizontally along the guide direction towards the lifting seat under the pulling action of the connecting rod and the guiding action of the guide arm 520, so as to realize the mold opening of each corner mold 120 and the room base F; Similarly, the lifting motion of the lifting seat in the second linkage structure 300 can make each inner side mold 130 move along the guide direction towards the lifting group under the pulling action of the corresponding connecting rod and the guiding action of the corresponding guide arm 520, so as to realize the mold opening of each inner side mold 130 and the room base F.

[0099] The guide frame 500 is arranged on the top of the outer side mold 720 in a lap joint and detachable manner when the core mold A is assembled to the outer mold B, so that the mold closing of the core mold A and the outer mold B is realized, and the relative position stability of the two is ensured. In addition, the guide frame 500 realizes the connection of each corner mold 120 and the inner side mold 130, and can improve the connection integrity of the corner mold 120 and the inner side mold 130. After the mold opening operation, the entire core mold A except the inner bottom mold 110 can be lifted out through the guide frame 500, so as to further improve the mold opening convenience of the core mold A, and the processing convenience and efficiency of the prefabricated room production line to the prefabricated room are further improved.

[0100] In this embodiment, as shown in Figures 6-9 The vertical shaft 600 can guide the vertical lifting movement of the two lifting seats to improve the stability and vertical position accuracy of the lifting movement of the lifting seat, and correspondingly ensure the linkage stability of the connecting rod to each corner mold 120 and the inner side mold 130, and reduce the occurrence of the connecting rod jamming or even sticking due to the deviation of the lifting seat.

[0101] Specifically, the plurality of corner molds 120 are arranged in a ring array, and correspondingly, the plurality of inner side molds 130 are also arranged in a ring array. The plurality of connecting rods of the linkage structure are uniformly and spacedly arranged along the circumference of the lifting seat. The plurality of guide arms 520 in the guide frame 500 are uniformly and spacedly arranged along the circumference of the connecting portion 510, and the vertical shaft 600 is connected to the center position of the connecting portion 510 of the guide frame 500. The lengths of the plurality of connecting rods in each linkage structure are equal. When the linkage structure is assembled to the corner mold 120 or the inner side mold 130, the circumferential corresponding positions of the connecting rod in the first linkage structure 200 and the corner mold 120 are not limited, and the circumferential corresponding positions of the connecting rod in the second linkage structure 300 and the inner side mold 130 are not limited, so as to improve the assembly convenience and efficiency of the linkage structure and the corner mold 120 and the inner side mold 130. At the same time, during the mold opening operation, the lifting movement of the lifting seat can drive each corner mold 120 or each inner side mold 130 to move towards the lifting seat at the same speed through the connecting rod, so as to improve the stability and smoothness of the mold opening operation, and reduce the occurrence of the interference between the corner mold 120 and the inner side mold 130. Similarly, the circumferential position of the guide frame 500 connected to the corner mold 120 and the inner side mold 130 is also not limited, so as to further improve the assembly convenience of the core mold A.

[0102] Specifically, the corner molds 120 and the inner side molds 130 can be four, the four corner molds 120 and the four inner side molds 130 surround the side wall of the rectangular room base F, and the outer mold B is also rectangular, and the two are combined to form a room base F with a regular rectangular shape.

[0103] Preferably, when the core mold A is in the combined state, each connecting rod is in the horizontal extension state, and when the mold is opened, the lifting movement direction of the lifting seat is not limited, and the lifting movement of the lifting seat can drive the opening of the corner mold 120 or the inner side mold 130, thereby improving the opening convenience of the core mold A.

[0104] In the embodiment, as shown in Figure 6 and Figure 9 , the connecting rods in the linkage structure are multiple groups, and the multiple groups of connecting rods are vertically spaced and arranged on the lifting seat. The multiple groups of connecting rods are connected to different height positions of the corner mold 120 or the inner side mold 130, and when the mold is opened, the multiple groups of connecting rods can exert a parallel pulling force on the different height positions of the corner mold 120 or the inner side mold 130 under the driving of the lifting movement of the lifting seat, thereby further improving the synchronous opening stability of the linkage structure to the corner mold 120 and the inner side 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 side mold 130, and the support of the corner mold 120 or the inner side mold 130 is stronger, thereby improving the stability of the corner mold 120 and the inner side mold 130, reducing the displacement of the corner mold 120 or the inner side mold 130 under the pressure of the poured material, causing the shape of the room base F formed by pouring to change, and even causing the material to leak.

[0105] In the embodiment, as shown in Figures 6-9 , the vertical shaft 600 is pivoted to the bottom of the guide frame 500 and includes a light shaft segment 610 and a threaded segment 620 along the axial direction thereof, and the light shaft segment 610 is provided with a stop structure; the lifting seat corresponding to the first linkage structure 200 of the corner mold 120 is a first lifting seat 210, and the connecting rod is a first connecting rod 220; the lifting seat corresponding to the second linkage structure 300 of the inner side mold 130 is a second lifting seat 310, and the connecting rod is a second connecting rod 320; the first lifting seat 210 is screwed to the threaded segment 620, the second lifting seat 310 is slidingly sleeved to the light shaft segment 610, and the end of the second lifting seat 310 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 A further includes a linkage arm, 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 by a predetermined length and is provided with a limiting convex protruding in the radial direction thereof, and the side of the limiting convex and the second lifting seat 310 facing each other is respectively provided with a first magnet and a second magnet capable of magnetic attraction.

[0106] The first linkage structure 200 is located below the second linkage structure 300, and the second lifting seat 310 is located below the stop structure and abuts against the stop structure when the angle die 120 and the inner side die 130 are connected to the inner bottom die 110 in the assembled state, the bottom end of the linkage arm as the first end thereof is connected to the first lifting seat 210, and the linkage arm passes through the insertion hole 311 upwardly and extends upwardly by a preset length.

[0107] When the angle die 120 and the inner side die 130 need to be operated, the vertical shaft 600 is driven to rotate in the first direction, the guide frame 500 limits the circumferential rotation of the first lifting seat 210 through the angle die 120 and the first connecting rod 220, and under the circumferential limiting action and the threaded rotation of the threaded section 620, the first lifting seat 210 moves downwardly along the threaded rod, and the linkage arm and the limiting protrusion thereon are pulled downwardly synchronously, each first connecting rod 220 pulls the corresponding angle die 120 to move synchronously toward the first lifting seat 210, thereby realizing the synchronous opening of the plurality of angle dies 120; meanwhile, in the process, the guide frame 500 limits the circumferential rotation of the second lifting seat 310 through the inner side die 130 and the second connecting rod 320, the vertical shaft 600 rotates relative to the second lifting seat 310, and the height of the second lifting seat 310 does not change.

[0108] Continuously, when the limiting protrusion descends to the top end of the insertion hole 311, the limiting protrusion abuts against the top end surface of the insertion hole 311, and 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 downwardly synchronously through the linkage arm and the limiting protrusion, correspondingly, the angle die 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 520, and the inner side die 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 520, thereby realizing the synchronous opening of the plurality of inner side dies 130, and the angle die 120 remains inside the inner side die 130 to reduce the interference to the movement of the inner side die 130.

[0109] Similarly, when the core mold A needs to be assembled, the vertical shaft 600 can be driven to rotate in the second direction, the first lifting seat 210 moves upward and drives the linkage arm and the limiting convex and the first magnet thereon 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 to move upward synchronously with the first lifting seat 210, correspondingly, the corner mold 120 and the inner side 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 continuous upward movement of the second lifting seat 310, the inner side mold 130 reaches the initial position, and with the continuous upward movement of the first lifting seat 210 pushing the linkage arm, the first magnet moves upward synchronously with the first lifting seat 210 until the first lifting seat 210 moves upward to the initial position, at this time, the corner mold 120 reaches the initial position and is assembled with the inner side mold 130 to form a ring-shaped side wall 14b again.

[0110] It can be seen that when the first linkage structure 200 and the second linkage structure 300 are connected to the vertical shaft 600 in the above linkage form, the opening and assembly of the corner mold 120 and the inner side mold 130 can be realized only by driving the rotating shaft to rotate, which is simple in structure and convenient to operate, thereby further improving the convenience and efficiency of the opening and assembly of the core mold A, and correspondingly further improving the processing convenience and efficiency of the prefabricated room production line for the prefabricated room.

[0111] In the embodiment, the guide frame 500 is provided with a rotating drive member, and the top end of the vertical shaft 600 is connected to the rotating drive member. When the corner mold 120 and the inner side mold 130 are opened and assembled, the rotating drive member can be started to drive the vertical shaft 600 to rotate, thereby ensuring the stability of the driving of the vertical shaft 600 to the corner mold 120 and the inner side mold 130, and reducing the consumption of manual labor.

[0112] Specifically, the rotating drive member can adopt a driving motor.

[0113] In addition to the above linkage form, the first linkage structure 200 and the second linkage structure 300, in the embodiment, the core mold A can further include a vertical sleeve shaft, the sleeve shaft including an outer shaft cylinder and a core shaft 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 core shaft and extends downward from the shaft segment of the sleeve shaft; the guide frame 500 is provided with a driving structure connected to the outer shaft cylinder and the core shaft, and configured to drive the outer shaft cylinder and the core shaft to rotate respectively.

[0114] The driving structure can specifically include two rotating drive members connected to the outer shaft cylinder and the core shaft respectively; and the first lifting seat 210 is screwed to the core shaft, and the second lifting seat 310 is screwed to the outer shaft cylinder, which is exemplarily introduced as follows:

[0115] 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.

[0116] Similarly, when it is necessary to assemble the core mold A, 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 14b.

[0117] This embodiment also provides another form of core mold A, such as Figures 11-15 As shown, the device includes a core mold body 100, a guide frame 500, and a linkage unit 20A. The core mold body 100 includes an inner bottom mold 110.

The corner mold 120 and the adjacent inner side mold 130 abut against each other on their opposite side end faces 14a to form a side enclosure 14b. The guide frame 500 includes a plurality of guide arms 520 arranged radially. The guide arms 520 are slidably connected to the tops of the corner mold 120 and the inner side mold 130, and the two side end faces 14a of the corner mold 120 are connected to the extensions of the corresponding guide arms 520. Parallel; the linkage unit 20A includes at least two linkage structures, each linkage structure including a turntable and multiple drive arms. The turntable has multiple strip holes 20c arranged circumferentially around its central region 20a, and each strip hole 20c includes a drive strip segment 201c whose radial distance from the central region 20a gradually decreases along its first extension direction. The first end of the drive arm is provided with a plug-in protrusion 14d, and multiple plug-in protrusions 14d are respectively slidably engaged with one of the strip holes 20c. The second end of the drive arm of one linkage structure is fixedly connected to multiple corner molds 120, and the second end of the drive arm of the other linkage structure is fixedly connected to multiple inner molds 130.

[0118] The core mold A is used in the mold of the prefabricated room production line. The form of the outer mold B in the mold can be the same as the outer mold B mentioned above. Specifically, for example...Figure 10 As shown, the outer mold B includes an outer bottom mold 710 and a plurality of outer side molds 720 surrounding the outer bottom mold 710, among the plurality of outer side molds 720, at most one outer side mold 720 is a fixed outer side mold 720, and the rest of the outer side molds 720 are movable outer side molds 720, and the movable outer side molds 720 are detachably connected with the outer bottom mold 710 and the adjacent outer side molds 720; the core mold A is contained in the space surrounded by the outer mold B, and a pouring cavity 800 is formed between the core mold A and the outer mold B.

[0119] In the core mold A provided by the embodiment, the edge of the inner bottom mold 110 includes a plurality of corner portions 111 and a side edge portion 112 between two corner portions 111, along the circumference of the inner bottom mold 110, the corner molds 120 are corner-shaped, and the number and shape of the corner molds 120 are adapted to the corner portions 111; the inner side molds 130 are arc-shaped or straight-line-shaped, and the number and shape of the inner side molds 130 are adapted to the side edge portion 112. The plurality of guide arms 520 of the guide frame 500 are arranged radially, and part of the guide arms 520 are first guide arms 520, the number of the first guide arms 520 is equal to the number of the corner molds 120 and is in one-to-one correspondence with the plurality of corner molds 120 for sliding connection, the extension direction of the first guide arms 520 in sliding connection is parallel to the extension direction of the side end surface 14a of the corner mold 120; the other part of the guide arms 520 are second guide arms 520, the number of the second guide arms 520 is equal to the number of the inner side molds 130 and is in one-to-one correspondence with the plurality of inner side molds 130 for sliding connection. In the linkage unit 20A, the structures of the linkage structures are similar, the rotating disc is divided into a center area 20a and an outer ring area 20b surrounding the center area 20a, each strip-shaped hole 20c is arranged in the outer ring area 20b, and one of the linkage structures is a first linkage structure 200, the rotating disc of the first linkage structure 200 is a first rotating disc 230, the driving arm is a first driving arm 240, the second ends of the plurality of first driving arms 240 respectively extend towards one of the corner molds 120 and are fixed to the corner mold 120; the other linkage structure is a second linkage structure 300, the rotating disc of the second linkage structure 300 is a second rotating disc 330, the driving arm is a second driving arm 340, the second ends of the plurality of second driving arms 340 respectively extend towards one of the inner side molds 130 and are fixed to the inner side mold 130, wherein the rotating discs of the first linkage structure 200 and the second linkage structure 300 are horizontally arranged, and the driving arms are preferably also horizontally arranged.

[0120] The core mold A is applied to the mold of the prefabricated room production line. In the production process, when the formed piece E reaches the mold opening station 41 for mold opening treatment, the mold opening of the core mold A: the connection of the corner mold 120, the inner side mold 130 and the inner bottom mold 110 is removed, and then the first rotating disc 230 is rotated circumferentially. Since the side end faces 14a on both sides of the corner mold 120 are parallel to the extension direction of the first guide arm 520 connected thereto, the corner mold 120 can slide along the extension direction of the first guide arm 520 without interference. Correspondingly, with the rotation of the driving bar section 201c, the insertion protrusion 14d gradually approaches the central area 20a in the radial direction under the guidance of the driving bar section 201c and the first guide arm 520, and the corresponding corner mold 120 is pulled towards the central area 20a by the first driving arm 240, until the corner mold 120 is separated from the inner side mold 130 and continues to move inward by a certain distance, thereby realizing the synchronous mold opening of the plurality of corner molds 120 and the room base F.

[0121] Continuously, similar to the synchronous mold opening of the plurality of corner molds 120 by the first linkage structure 200, the second rotating disc 330 is rotated circumferentially. When the insertion protrusion 14d of the second linkage structure 300 is slidably inserted into the driving bar section 201c thereof, with the rotation of the driving bar section 201c, the insertion protrusion 14d gradually approaches the central area 20a in the radial direction under the guidance of the driving bar section 201c and the second guide arm 520, and the corresponding inner side mold 130 is pulled towards the central area 20a by the second driving arm 340, thereby realizing the synchronous mold opening of the plurality of inner side molds 130 and the room base F; then the connection of the guide frame 500 and the outer side mold 720 is removed, and the core mold A in the mold opening state is taken out from the top opening of the room base F; wherein the inner bottom mold 110 is sent to the conveying area 31b of the first curing bin 31, and the other components of the core mold A are sent to the upper conveying layer 71.

[0122] Assembly of the core mold A: when the inner bottom mold 110 and the other components of the core mold A are conveyed to the core mold pretreatment station 81a, the bottom end of each corner mold 120 is connected to a corresponding corner portion 111, and each inner side mold 130 is connected to a corresponding side edge portion 112. At this time, the corner molds 120 and the inner side molds 130 jointly form an annular side wall 14b, and the side end faces 14a on both sides of the corner molds 120 are planar and approximately fit between the side end faces 14a of the adjacent inner side molds 130 along the circumference of the side wall 14b; the first rotating disc 230 and the first driving arm 240 of the first linkage structure 200 are in the first mold closing position under the restriction of each corner mold 120 and the first guide arm 520, and the insertion protrusion 14d of the first driving arm 240 can be inserted into the driving bar section 201c of the bar-shaped hole 20c; the second rotating disc 330 and the second driving arm 340 of the second linkage structure 300 are in the second mold closing position under the restriction of each inner side mold 130.

[0123] The opening of the outer mold B, the assembly of the outer mold B, and the closing of the core mold A and the outer mold B can be the same as the operations in the connecting rod type mold described above, and will not be described here.

[0124] The core mold A provided in the embodiment is applied to a prefabricated room production line, and the two linkage structures are respectively linked to the plurality of corner molds 120 and the plurality of inner side molds 130. In the opening operation, the synchronous opening of the plurality of corner molds 120 and the synchronous opening of the plurality of inner side molds 130 can be realized by driving the rotating movement of the rotating disc of the two linkage structures. The opening operation is convenient and efficient, thereby greatly improving the processing convenience and efficiency of the prefabricated room production line for the prefabricated room.

[0125] The setting of the guide frame 500 can further improve the opening convenience of the core mold A, and correspondingly further improve the processing convenience and efficiency of the prefabricated room production line for the prefabricated room.

[0126] As shown in the embodiment, Figures 11-15 The guide frame 500 is pivoted with a vertical shaft 600. The linkage structure corresponding to the corner mold 120 is the first linkage structure 200, and the linkage structure corresponding to the inner side mold 130 is the second linkage structure 300. The rotating discs of the first linkage structure 200 and the second linkage structure 300 are fixedly sleeved on the vertical shaft 600 and arranged in an upper and lower interval. The insertion protrusion 14d of the first linkage structure 200 is slidingly connected to the corresponding driving bar-shaped segment 201c. The bar-shaped hole 20c of the second linkage structure 300 further includes a follow-up circular arc segment 202c. Along the first extension direction of the bar-shaped hole 20c, the follow-up circular arc segment 202c is connected to the first end of the driving bar-shaped segment 201c, and the follow-up circular arc segment 202c is coaxially arranged with the central region 20a. The insertion protrusion 14d of the second linkage structure 300 is slidingly connected to the corresponding follow-up circular arc segment 202c.

[0127] The extension area of the strip-shaped hole 20c of the first linkage structure 200 and the second linkage structure 300 is consistent in the circumferential direction. When the mold opening operation of the core mold A is performed, the vertical shaft 600 can be driven to rotate to drive the first rotating disc 230 and the second rotating disc 330 to rotate synchronously. In the first stage, with the rotation of the first rotating disc 230 and the second rotating disc 330, in the first linkage structure 200, the radial distance between the driving strip-shaped section 201c and the central area 20a gradually decreases, the insertion protrusion 14d gradually approaches the central area 20a under the guiding action of the driving strip-shaped section 201c and the first guiding arm 520, and the corner mold 120 synchronously approaches the central area 20a under the pulling action of the insertion protrusion 14d and the first driving arm 240 and is separated from the inner side mold 130 by a certain distance, so as to realize the mold opening of the plurality of corner molds 120 and the room base body F. In the second linkage structure 300, the radial distance between the driven circular arc section 202c and the central area 20a is unchanged, and the insertion protrusion 14d remains stationary under the guiding action of the driven circular arc section 202c and the second guiding arm 520.

[0128] Continuously, in the second stage, with the continuous rotation of the first rotating disc 230 and the second rotating disc 330, in the first linkage structure 200, the radial distance between the driving strip-shaped section 201c and the central area 20a continues to gradually decrease, and the insertion protrusion 14d continues to pull the corner mold 120 to move towards the central area 20a through the first driving arm 240, so as to reduce the interference of the corner mold 120 to the mold opening of the inner side mold 130. In the second linkage structure 300, the insertion protrusion 14d enters the driving strip-shaped section 201c from the driven circular arc section 202c, the radial distance between the driving strip-shaped section 201c and the central area 20a gradually decreases, the insertion protrusion 14d gradually approaches the central area 20a under the guiding action of the driving strip-shaped section 201c and the second guiding arm 520, and the inner side mold 130 synchronously approaches the central area 20a under the pulling action of the insertion protrusion 14d and the second driving arm 340 and is separated from the pre-branch direction, so as to realize the mold opening of the plurality of inner side molds 130 and the room base body F.

[0129] Similarly, when the core mold A is assembled, the vertical shaft 600 can be driven to rotate reversely. Then, the inner side mold 130 first moves away from the central area 20a to the initial position under the driving and guiding action of the second linkage structure 300, and then the corner mold 120 moves away from the central area 20a to the initial position under the driving and guiding action of the first linkage structure 200, so as to realize the position assembly of the corner mold 120 and the inner side mold 130, and then the corner mold 120 and the inner side mold 130 can be correspondingly connected to the inner bottom mold 110.

[0130] The core mold A provided by the embodiment can realize synchronous mold opening of the plurality of corner molds 120 and synchronous mold opening of the plurality of inner side molds 130 by rotating the vertical shaft 600, and can ensure stable operation of the mold opening operation, thereby further improving the mold opening convenience and efficiency of the core mold A, and correspondingly further improving the processing convenience and efficiency of the prefabricated room production line on the prefabricated room. At the same time, the position assembly of the corner molds 120 and the inner side molds 130 can be realized by rotating the vertical shaft 600, thereby improving the assembly convenience and efficiency of the core mold A, and correspondingly further improving the processing convenience and efficiency of the prefabricated room production line on the prefabricated room.

The vertical shaft 600 is rotationally connected to the center position of the connecting portion 510 of the guide frame 500, and the connecting portion 510, the first rotating disc 230 and the second rotating disc 330 are coaxially arranged. The lengths of the plurality of first driving arms 240 in the first linkage structure 200 are equal, and there is no limitation on the circumferential corresponding positions of the first driving arms 240 and the corner molds 120 when the first linkage structure 200 is assembled to the corner molds 120. Similarly, there is no limitation on the circumferential corresponding positions of the second driving arms 340 and the inner side molds 130 when the second linkage structure 300 is assembled to the inner side molds 130, thereby improving the assembly convenience and efficiency of the linkage structure, the corner molds 120 and the inner side molds 130. At the same time, during the mold opening operation, the rotating movement of the rotating discs can drive the movement of each corner mold 120 or each inner side mold 130 at the same speed towards the center area 20a, thereby improving the stability and smoothness of the mold opening operation, and further reducing the occurrence of interference between the corner molds 120 and the inner side molds 130. Similarly, there is no limitation on the circumferential positions of the guide frame 500 when it is connected to the corner molds 120 and the inner side molds 130, thereby further improving the assembly convenience of the core mold A.

Specifically, the first guide 250 can include a first sleeving portion, the outer periphery of the first sleeving portion is provided with a plurality of first extension arms 251 extending in a radial manner, each first extension arm 251 is provided with a first guide groove 252 along the extension direction thereof; the first sleeving portion can be rotatably sleeved on the vertical shaft 600 through a bearing to realize the relative rotation in the circumferential direction and the axial fixation relative to the vertical shaft 600.
