[0079] The core mold A is applied to the mold of the prefabricated room production line. During the production process, when the molded part E arrives at the mold opening station 41 for mold opening, the connection between the corner mold 120, the inner mold 130 and the inner bottom mold 110 is removed, and then the multiple corner molds 120 are driven to move together through the linkage unit, thereby realizing the synchronous mold opening of the multiple corner molds 120 and the prefabricated room; similarly, the multiple inner molds 130 are driven to move together through the linkage unit, thereby realizing the synchronous mold opening of the 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.
[0080] 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 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 through the linkage unit. 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.
[0081] This embodiment also provides a core mold A, which is applied to the mold in the above-mentioned prefabricated room production line, such as Figure 4-Figure 6 As shown, the core mold A includes a core mold body 100 and two linkage structures, 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 the corner mold 120, the side portion 112 is detachably connected to the inner side mold 130, and the corner mold 120 and the adjacent inner side mold 130 are in contact with each other at the side end faces 14a; the linkage structure includes a lifting seat and a plurality of connecting rods located above the inner bottom mold 110, the first ends of the plurality of connecting rods are hinged to the lifting seat and arranged at intervals along the circumference of the lifting seat, and the plurality of connecting rods extend horizontally or extend toward the same side of the lifting seat in the up and down direction; the second end of the connecting rod of one of the linkage structures is respectively hinged to one of the corner molds 120, and the extension direction of each connecting rod is parallel to the side end faces 14a of the hinged corner mold 120; the second end of the connecting rod of the other linkage structure is respectively hinged to one of the inner side molds 130.
[0082] like Figure 3 As shown, the outer mold B of the mold in the prefabricated room production line may include an outer bottom mold 710 and a plurality of outer molds 720 surrounding the outer bottom mold 710, among the plurality of outer molds 720, at most one outer mold 720 serves as a fixed outer mold 720, and the remaining outer molds 720 serve as movable outer molds 720, and the movable outer molds 720 are all detachably connected to the outer bottom mold 710 and the adjacent outer molds 720; the core mold A is accommodated in the space surrounded by the outer mold B, and a casting cavity 800 is surrounded by the core mold A and the outer mold B.
[0083] In the core mold A provided in this embodiment, Figure 6 As shown, 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 molds 120 are corner-shaped, and their number and shape are adapted to the corners 111; the inner side molds 130 are arc-shaped or straight-line-shaped, and their number and shape are adapted to the side portions 112. The linkage unit includes two linkage structures, and in the linkage structures, the first ends of multiple 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 multiple 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 multiple connecting rods are horizontally extended away from the lifting seat, or the multiple connecting rods are inclined upwardly extended away from the lifting seat, or the multiple 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).
[0084] The core mold A is used in the mold of the prefabricated room production line. During the production process, when the molded part E arrives at the mold opening station 41 for mold opening processing, in the core mold A, the second ends of the connecting rods of one of the linkage structures are respectively hinged to one of the corner molds 120, and the linkage structure is defined as the first linkage structure 200; the second ends of the connecting rods of the other linkage structure are respectively hinged to one of the inner molds 130, and the linkage structure is defined as the second linkage structure 300.
[0085] Among them, Figure 7-Figure 9As shown, the core mold A is opened: 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 can pull The movable corner mold 120 moves 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 room matrix F; wherein, when the connecting rod extends upwardly and tilted 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 room matrix F; when the connecting rod extends downwardly and tilted 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 room matrix F.
[0086] 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 room matrix F; then, the core mold A in the mold opening state is taken out from the top opening of the room matrix 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 transported 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 mold 130 is connected to a corresponding side portion 112. At this time, the corner mold 120 and the inner mold 130 jointly form an annular side enclosure 14b, and along the circumference of the side enclosure 14b, the side end faces 14a on both sides of the corner mold 120 are both flat and approximately fit with the side end faces 14a of the adjacent inner mold 130; the first linkage The first linkage structure 200 is in the first mold clamping position under the restriction of each corner mold 120, and in the first mold clamping position, each connecting rod of the first linkage structure 200 extends horizontally in the direction away from its lifting seat, extends obliquely upward of the lifting seat, or extends obliquely downward of the lifting seat; the second linkage structure 300 is in the second mold clamping position under the restriction of each inner mold 130, and in the second mold clamping position, each connecting rod of the second linkage structure 300 extends horizontally in the direction away from its lifting seat, extends obliquely upward of the lifting seat, or extends obliquely downward of the lifting seat.
[0088] Opening of the outer mold B: At the mold opening station 41 , the connection between each movable outer mold 720 and the adjacent outer mold 720 and the outer bottom mold 710 is removed, and each movable outer mold 720 is pulled outward from the room base F, thereby realizing the opening of the outer mold B and sending it to the lower conveying layer 72 .
[0089] Assembly of the outer mold B: When the outer mold B in the open mold state is conveyed to the outer mold preprocessing station 82a, each movable outer mold 720 is detachably fixed to the corresponding edge segment of the outer bottom mold 710, and adjacent outer molds 720 are detachably fixed to each other, thereby enclosing a receiving cavity with a top opening.
[0090] Then, 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. 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 closed mold state is inserted into the accommodating cavity from the top opening of the outer mold B in the closed mold state to form an integrated casting mold C, wherein the top of the core mold A can be lower than, equal to or higher than the outer 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 a bottom casting space is formed therebetween, and an annular side casting space is formed between the side enclosure 14b formed by the corner mold 120 and the inner mold 130 of the core mold A and the outer mold 720 of the outer mold B, and the bottom casting space and the side casting space are connected to form a casting cavity 800.
[0092] Among them, one of the inner molds 130 of the core mold A can be provided with a first opening 131, and the outer mold 720 of the outer mold B is provided with a second opening 721 corresponding to the first opening 131, and the outer wall of the inner mold 130 is provided with an annular platform 722 surrounding the first opening 131, or the inner wall of the outer mold 720 is provided with an annular platform 722 surrounding the second opening 721. When the core mold A is assembled to the outer mold B, the first opening 131 corresponds to the second opening 721, and the annular platform 722 is surrounded between the first opening 131 and the second opening 721. Among them, the outer wall of the inner mold 130 or the inner wall of the outer mold 720 can be provided with pre-processed parts such as steel bars and pipelines as needed.
[0093] Specifically, the core mold A and the outer mold B can be connected by a hanging structure, a snap-fit structure, an overlapping structure, etc., and the fixation of the relative position can be ensured.
[0094] The pouring device 20 can input cement concrete and other materials into the pouring cavity 800 through its material conveying pipe 21 until the materials fill the bottom pouring space and the side pouring space of the preset height, thereby completing the integral pouring and forming of the room matrix F; specifically, Figure 4 and Figure 6 As shown, 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 downward through the inner bottom mold 110; during pouring, the output end of the material conveying pipe 21 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.
[0095] The core mold A provided in this embodiment is applied to the prefabricated room production line, 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 prefabricated room production line for the prefabricated rooms.
[0096] In this embodiment, Figure 3As shown, the outer mold B may also include a base 730, the top surface of the base 730 is provided with a plurality of radially arranged guide rails 731, and the plurality of guide rails 731 correspond to the plurality of outer molds 720 one by one; a wheel seat 723 is provided at the bottom of each outer mold 720, and a guide wheel 724 is rollingly connected to the bottom of the wheel seat 723, and the guide wheel 724 is rollingly connected to one of the guide rails 731. When the outer mold B is opened, after the connection between the bottom mold and the outer mold 720 and the adjacent outer mold 720 is removed, each outer mold 720 can be pushed along the corresponding guide rail 731, so as to conveniently complete the opening operation of the outer mold B. Among them, a support rib 740 may also be connected between the wheel seat 723 and the corresponding outer mold 720 to improve the strength of the outer mold 720 and reduce the deformation of the outer mold 720 during the casting process.
[0097] In this embodiment, Figure 4 As shown, the core mold A also includes a guide frame 500, which includes a connecting portion 510 and a plurality of guide arms 520 provided on the connecting portion 510 and arranged radially; the guide arms 520 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 520 and the corresponding connecting rods to the same horizontal plane are collinear. The number of guide arms 520 in the guide frame 500 is equal to the sum of the numbers of the corner molds 120 and the inner molds 130. The multiple guide arms 520 extend horizontally and correspond to one of the corner molds 120 or the inner molds 130 respectively. Each guide arm 520 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 520 slidably connected to the top thereof are a group, and the guiding direction of the guide arms 520 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 520 slidably connected to the top thereof are a group, and the guiding direction of the guide arms 520 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.
[0098] During the opening process of the core mold A, 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 520 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 520, so as to realize the opening of each corner mold 120 and the room matrix F; similarly, the lifting and lowering movement of the lifting seat in the second linkage structure 300 can enable each inner side 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 520, so as to realize the opening of each inner side mold 130 and the room matrix F.
[0099] Among them, the setting of the guide frame 500, in addition to improving the stability of the corner mold 120 and the inner mold 130 during the mold opening operation as mentioned above, when the core mold A is assembled on the outer mold B, the guide frame 500 can be overlapped and detachably fixed to the top of the outer mold 720, thereby realizing the mold closing of the core mold A and the outer mold B and ensuring the relative position stability of the two; in addition, the guide frame 500 realizes the connection between each corner mold 120 and the inner mold 130, which can improve the connection integrity between the corner mold 120 and the inner mold 130. After the mold opening operation, the entire core mold A except the inner bottom mold 110 can be lifted out by the guide frame 500, thereby further improving the mold opening convenience of the core mold A, and correspondingly further improving the processing convenience and processing efficiency of the prefabricated room production line for the prefabricated rooms.
[0100] In this embodiment, Figure 6-Figure 9 As shown, the guide frame 500 is provided with a vertical shaft 600, and two lifting seats are arranged up and down and are both sleeved on the vertical shaft 600. The lifting seats are configured to be able to move up and down relative to the vertical shaft 600 along the axial direction of the vertical shaft 600. During the mold opening and closing operation, in the process of driving the two lifting seats to move up and down, the vertical shaft 600 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.
[0101] 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 520 in the guide frame 500 are evenly spaced along the circumference of the connecting part 510, and the vertical axis 600 is connected to the center position of the connecting part 510 of the guide frame 500. 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 convenience and efficiency of assembling the linkage structure with 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, 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 500 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 A.
[0102] Specifically, there can be four corner molds 120 and four inner molds 130, and the four corner molds 120 and the four inner molds 130 form a rectangular side enclosure 14b, and the outer mold B is also correspondingly rectangular, and the two are combined to form a regular rectangular room matrix F.
[0103] Preferably, when the core mold A is in the mold closing state, each connecting rod is in a horizontally extended state. Then, 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 opening the core mold A.
[0104] In this embodiment, Figure 6 and Fig. 9 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 deviation 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 room matrix F formed by pouring, and even causing serious leakage of materials.
[0105] In this embodiment, Figure 6-Figure 9 As shown, the vertical shaft 600 is pivotally connected to the bottom of the guide frame 500 and includes an optical axis section 610 and a threaded section 620 along its axial direction. The optical axis section 610 is provided with a stop structure; the lifting seat corresponding to the first linkage structure 200 of the angle mold 120 is the first lifting seat 210, and the connecting rod is the first connecting rod 220; the lifting seat corresponding to the second linkage structure 300 of the inner mold 130 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 620, and the second lifting seat 3 10 is slidably sleeved on the optical axis section 610, and one 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 plug hole 311, and the core mold A also includes a linkage arm, a first end of the linkage arm is connected to the first lifting seat 210, a second end of the linkage arm passes through the plug hole 311 and extends 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 one side facing the first magnet and the second magnet.
[0106] Taking the optical axis segment 610 being located above the threaded segment 620 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.
[0107] When it is necessary to open the corner mold 120 and the inner mold 130, the vertical shaft 600 is driven to rotate in the first direction, and the guide frame 500 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 620, 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 500 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 600 rotates relative to the second lifting seat 310, and the height of the second lifting seat 310 remains unchanged.
[0108] 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 520. 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 520, 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.
[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 protrusion thereon and the first magnet to move upward 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 move upward 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 rise 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 the annular side enclosure 14b again.
[0110] 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 600 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 A, and correspondingly further improving the processing convenience and efficiency of the prefabricated room production line for the prefabricated rooms.
[0111] In this embodiment, the guide frame 500 is provided with a rotating driving member, and the top end of the vertical shaft 600 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 600, thereby ensuring the stability of the vertical shaft 600 rotating the diagonal mold 120 and the inner mold 130 and reducing the consumption of manual labor.
[0112] Specifically, the rotation driving member may be a driving motor.
[0113] 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 A 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 500 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.
[0114] 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:
[0115] 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.
[0116] Similarly, when the core mold A 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 14b.
[0117] This embodiment also provides another form of core mold A, such as Figure 11-Figure 15 As shown, it includes a core mold body 100, a guide frame 500 and a linkage unit 20A, wherein the core mold body 100 includes an inner bottom mold 110, the corner portion 111 of the inner bottom mold 110 is detachably connected to the corner mold 120, and the side portion 112 is detachably connected to the inner side mold 130, and the side end faces 14a of the corner mold 120 and the adjacent inner side mold 130 are matched and abutted against each other to form a side enclosure 14b; the guide frame 500 includes a plurality of guide arms 520 arranged radially, and the guide arms 520 are slidably connected to the tops of the corner mold 120 and the inner side mold 130 in a one-to-one correspondence, and the side end faces 14a on both sides of the corner mold 120 are in contact with the extension sides of the corresponding guide arms 520. parallel to the direction; the linkage unit 20A includes at least two linkage structures, the linkage structure includes a turntable and a plurality of driving arms, the turntable is provided with a plurality of strip holes 20c circumferentially arranged in its central area 20a, and each strip hole 20c includes a driving strip segment 201c whose radial distance from the central area 20a gradually decreases along its first extension direction; the first end of the driving arm is provided with an insertion protrusion 14d, and the plurality of insertion protrusions 14d are respectively correspondingly slidably engaged with one of the strip holes 20c; the second end of the driving arm of one of the linkage structures is fixedly connected to the plurality of corner molds 120 one by one, and the second end of the driving arm of the other linkage structure is fixedly connected to the plurality of inner molds 130 one by one.
[0118] The core mold A is used for the mold in the prefabricated room production line. The form of the outer mold B in the mold can be the same as the above-mentioned outer mold B. Specifically, Fig.10 As shown, the outer mold B includes an outer bottom mold 710 and a plurality of outer molds 720 arranged around the outer bottom mold 710. Among the plurality of outer molds 720, at most one outer mold 720 serves as a fixed outer mold 720, and the remaining outer molds 720 serve as movable outer molds 720. The movable outer molds 720 are detachably connected to the outer bottom mold 710 and the adjacent outer molds 720. The core mold A is accommodated in the space surrounded by the outer mold B, and a casting cavity 800 is formed between the core mold A and the outer mold B.
[0119] In the core mold A provided in this embodiment, the edge of the inner bottom mold 110 includes a plurality of corners 111 and a side portion 112 located between two corners 111. Along the circumference of the inner bottom mold 110, the corner mold 120 is a corner shape, and its number and shape are adapted to the corner 111; the inner side mold 130 is an arc or a straight line, and its number and shape are adapted to the side portion 112. The plurality of guide arms 520 of the guide frame 500 are arranged radially, and a part of the guide arms 520 are used as first guide arms 520, the number of which is equal to the number of the corner molds 120 and is slidably connected to the plurality of corner molds 120 in a one-to-one correspondence, and the extension direction of the slidably connected first guide arms 520 is parallel to the extension direction of the side end surfaces 14a on both sides of the corner mold 120; the other part of the guide arms 520 are used as second guide arms 520, the number of which is equal to the number of the inner side molds 130 and is slidably connected to the plurality of inner side molds 130 in a one-to-one correspondence. In the linkage unit 20A, the structures of each linkage structure are similar. The turntable is divided into a central area 20a and an outer ring area 20b surrounding the central area 20a. Each strip hole 20c is arranged in the outer ring area 20b, and one of the linkage structures serves as the first linkage structure 200, its turntable serves as the first turntable 230, and the driving arm serves as the first driving arm 240, and the second ends of its multiple first driving arms 240 respectively extend toward one of the corner molds 120 and are fixed to the corner mold 120; the other linkage structure serves as the second linkage structure 300, its turntable serves as the second turntable 330, and the driving arm serves as the second driving arm 340, and the second ends of its multiple second driving arms 340 respectively extend toward one of the inner molds 130 and are fixed to the inner mold 130, wherein the turntables 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 used in the mold of the prefabricated room production line. During the production process, when the molded part E arrives at the mold opening station 41 for mold opening processing, the core mold A is opened by removing the connection between the corner mold 120, the inner mold 130 and the inner bottom mold 110, and then rotating the first turntable 230 circumferentially. Since the side end surfaces 14a on both sides of the corner mold 120 are parallel to the extension direction of the first guide arm 520 to which it is slidably connected, the corner mold 120 can slide along the extension direction of the first guide arm 520 without interference. Accordingly, as the driving strip segment 201c rotates, the plug-in protrusion 14d gradually approaches the central area 20a in the radial direction under the guiding action of the driving strip segment 201c and the first guide arm 520, and pulls the corresponding corner mold 120 toward the central area 20a through the first driving arm 240 until the corner mold 120 is separated 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 room matrix F.
[0121] Continuing, similar to the synchronous mold opening of multiple corner molds 120 by the first linkage structure 200, the second turntable 330 is rotated circumferentially. When the plug-in protrusion 14d of the second linkage structure 300 is slidably plugged into its driving strip segment 201c, as the driving strip segment 201c rotates, the plug-in protrusion 14d gradually approaches the central area 20a in the radial direction under the guidance of the driving strip segment 201c and the second guide arm 520, and pulls the corresponding inner mold 130 toward the central area 20a through the second driving arm 340, thereby realizing the synchronous mold opening of multiple inner molds 130 and the room matrix F; then, the connection between the guide frame 500 and the outer mold 720 is removed, and the core mold A in the mold opening state is taken out from the top opening of the room matrix 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 other components of the core mold A are transported to the core mold pre-processing station 81a, the bottom end of each corner mold 120 is connected to a corresponding corner portion 111, and each inner mold 130 is connected to a corresponding side portion 112. At this time, the corner mold 120 and the inner mold 130 jointly form an annular side enclosure 14b, and along the circumference of the side enclosure 14b, the side end faces 14a on both sides of the corner mold 120 are both flat and aligned with the adjacent inner side. The side end surfaces 14a of the mold 130 are approximately fitted together; the first turntable 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 plug-in protrusion 14d of the first driving arm 240 can be plugged into the driving strip segment 201c of the strip hole 20c; the second turntable 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 mold 130.
[0123] Among them, 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 above-mentioned connecting rod type mold, which will not be repeated here.
[0124] The core mold A provided in this embodiment is applied to the prefabricated room production line, 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 rotational movement of the turntables 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 the prefabricated rooms.
[0125] Among them, with the setting of the guide frame 500, 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, thereby further improving the mold opening convenience of the core mold A, and correspondingly further improving the processing convenience and efficiency of the prefabricated room production line for the prefabricated rooms.
[0126] In this embodiment, Figure 11-Figure 15 As shown, the guide frame 500 is pivotally connected to a vertical axis 600, the linkage structure corresponding to the corner mold 120 is the first linkage structure 200, and the linkage structure corresponding to the inner mold 130 is the second linkage structure 300. The turntables of the first linkage structure 200 and the second linkage structure 300 are fixedly sleeved on the vertical axis 600 and arranged at intervals up and down; the plug-in protrusion 14d of the first linkage structure 200 is slidably engaged with the corresponding driving strip segment 201c; the strip hole 20c of the second linkage structure 300 also includes a follower arc segment 202c, along the first extension direction of the strip hole 20c, the follower arc segment 202c is connected to the head end of the driving strip segment 201c, and the follower arc segment 202c is coaxially arranged with the central area 20a, and the plug-in protrusion 14d of the second linkage structure 300 is slidably engaged with the corresponding follower arc segment 202c.
[0127] The circumferential extension area of the strip holes 20c of the first linkage structure 200 and the second linkage structure 300 is consistent. When the core mold A is opened, the vertical shaft 600 can be driven to rotate to drive the first turntable 230 and the second turntable 330 to rotate synchronously with it. In the first stage, as the first turntable 230 and the second turntable 330 rotate, the radial distance between the driving strip segment 201c and the central area 20a in the first linkage structure 200 gradually decreases, and the plug-in protrusion 14d is between the driving strip segment 201c and the first Under the guidance of the guide arm 520, the corner mold 120 gradually approaches the central area 20a, and under the pulling action of the plug-in protrusion 14d and the first driving arm 240, the corner mold 120 synchronously approaches the central area 20a and separates from the inner mold 130 by a certain distance, thereby realizing the mold opening of multiple corner molds 120 and the room matrix F; in the second linkage structure 300, the radial distance between the follower arc segment 202c and the central area 20a remains unchanged, and the plug-in protrusion 14d remains fixed under the guidance of the follower arc segment 202c and the second guide arm 520.
[0128] Continuing, entering the second stage, as the first turntable 230 and the second turntable 330 continue to rotate, in the first linkage structure 200, the radial distance between the driving strip segment 201c and the central area 20a continues to gradually decrease, and the plug-in protrusion 14d continues to pull the corner mold 120 toward the central area 20a through the first driving arm 240 to reduce the interference of the corner mold 120 on the opening of the inner mold 130; in the second linkage structure 300, the plug-in protrusion 14d enters the driving strip segment 201c from the follower arc segment 202c, and the radial distance between the driving strip segment 201c and the central area 20a gradually decreases. Under the guidance of the driving strip segment 201c and the second guide arm 520, the plug-in protrusion 14d gradually approaches the central area 20a, and the inner mold 130 is synchronously approached to the central area 20a and separated from the pre-support direction under the pulling action of the plug-in protrusion 14d and the second driving arm 340, thereby realizing the opening of multiple inner molds 130 and the room matrix F.
[0129] Similarly, when the core mold A is assembled, the vertical axis 600 can be driven to rotate in the opposite direction, and then the inner 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, thereby realizing the positional assembly of the corner mold 120 and the inner mold 130, and then the corner mold 120 and the inner mold 130 are correspondingly connected to the inner bottom mold 110.
[0130] The core mold A provided in the present embodiment, through the setting of the above-mentioned vertical axis 600, can realize the synchronous mold opening of multiple corner molds 120 and the synchronous mold opening of multiple inner molds 130 in succession only by rotating the vertical axis 600, and can ensure the 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 processing efficiency of the prefabricated room production line for the prefabricated rooms; at the same time, the position assembly of the corner mold 120 and the inner mold 130 can be achieved only by rotating the vertical axis 600, thereby improving the assembly convenience and efficiency of the core mold A, and correspondingly further improving the processing convenience and processing efficiency of the prefabricated room production line for the prefabricated rooms.
[0131] Specifically, a rotation driving member may be provided on the guide frame 500 , and the rotation driving member is transmission-connected to the vertical shaft 600 to realize driving the vertical shaft 600 to rotate; wherein the rotation driving member may be a driving motor.
[0132] Specifically, multiple corner molds 120 are arranged in a circular array, and correspondingly, multiple inner molds 130 are also arranged in a circular array. The multiple first driving arms 240 of the first linkage structure 200 are evenly spaced along the circumference of the first turntable 230, and the multiple second driving arms 340 of the second linkage structure 300 are evenly spaced along the circumference of the second turntable 330; the multiple guide arms 520 in the guide frame 500 can all be connected to the connecting part 510, and are evenly spaced along the circumference of the connecting part 510, and the vertical axis 600 is rotatably connected to the center position of the connecting part 510 of the guide frame 500, wherein the connecting part 510, the first turntable 230, and the second turntable 330 are coaxially arranged. The lengths of the plurality of first driving arms 240 in the first linkage structure 200 are all equal. When the first linkage structure 200 is assembled to the corner mold 120, there is no restriction on the circumferential corresponding positions of the first driving arms 240 and the corner mold 120. Similarly, when the second linkage structure 300 is assembled to the inner mold 130, there is no restriction on the circumferential corresponding positions of the second driving arms 340 and the inner mold 130, thereby improving the convenience and efficiency of assembling the linkage structure with the corner mold 120 and the inner mold 130. At the same time, during the mold opening operation, the rotating motion of the turntable can drive the movement speed of each corner mold 120 or each inner mold 130 toward the central area 20a through the driving arm, thereby improving the stability and smoothness of the mold opening operation, and further 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 500 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 A.
[0133] In this embodiment, Fig.15As shown, the first linkage structure 200 includes a first guide member 250 rotatably sleeved on the vertical shaft 600, the first guide member 250 includes a plurality of first guide grooves 252 arranged radially, a plurality of driving arms of the first linkage structure 200 are slidably connected to the plurality of first guide grooves 252 one by one, and the plurality of first guide grooves 252 are parallel to the corresponding guide arms 520. Multiple first guide grooves 252 are located one by one below the multiple first guide arms 520 and are parallel to the corresponding first guide arms 520. When the first turntable 230 is driven to rotate, so as to drive the plug-in protrusion 14d to radially approach or move away from the central area 20a by driving the strip segment 201c, the first guide arm 520 can guide the radial movement of the plug-in protrusion 14d once through the corner mold 120 and the first driving arm 240, and the first guide groove 252 can guide the radial movement of the plug-in protrusion 14d by the first driving arm 240 twice, thereby improving the linkage stability and smoothness of the first linkage structure 200 and ensuring the smooth and synchronous mold opening of the corner mold 120. Specifically, the first guide member 250 may include a first sleeve portion, the outer periphery of which is provided with a plurality of radially extending first extension arms 251, and each first extension arm 251 is provided with a first guide groove 252 along its extension direction; the first sleeve portion can be rotatably sleeved on the vertical shaft 600 through a bearing to achieve circumferential relative rotation and axial relative fixation with the vertical shaft 600.
[0134] Similarly, if Fig.14 As shown, the second linkage structure 300 includes a second guide member 350 rotatably sleeved on the vertical shaft 600, the second guide member 350 includes a plurality of second guide grooves 352 arranged radially, a plurality of driving arms of the second linkage structure 300 are slidably connected to the plurality of second guide grooves 352 one by one, and the plurality of second guide grooves 352 are parallel to the corresponding guide arms 520. A plurality of second guide grooves 352 are correspondingly located below the plurality of second guide arms 520 and are parallel to the corresponding second guide arms 520. When the second turntable 330 is driven to rotate, so as to drive the plug-in protrusion 14d to radially approach or move away from the central area 20a by driving the strip segment 201c, the second guide arm 520 can guide the radial movement of the plug-in protrusion 14d once through the inner mold 130 and the second driving arm 340, and the second guide grooves 352 can guide the radial movement of the plug-in protrusion 14d by the second driving arm 340 twice, thereby improving the linkage stability and smoothness of the second linkage structure 300 and ensuring the smooth and synchronous mold opening of the inner mold 130. Specifically, the second guide member 350 may include a second sleeve portion, the outer periphery of which is provided with a plurality of radially extending second extension arms 351, and each second extension arm 351 is provided with a second guide groove 352 along its extension direction; the second sleeve portion can be rotatably sleeved on the vertical shaft 600 through a bearing to achieve circumferential relative rotation and axial relative fixation with the vertical shaft 600.
[0135] In this embodiment, Fig.13 As shown, the number of linkage structures in the linkage unit 20A is three, and another linkage structure other than the first linkage structure 200 and the second linkage structure 300 is used as the third linkage structure 400. In the third linkage structure 400, the turntable is fixedly sleeved on the vertical shaft 600, and the plug-in protrusion 14d is slidably plugged into the corresponding driving strip segment 201c; the third linkage structure 400 also includes a third guide member 440 that is rotatably sleeved on the vertical shaft 600 and relatively fixed to the guide frame 500, and the third guide member 440 includes a plurality of third guide grooves 442 arranged radially, The multiple driving arms of the third linkage structure 400 are slidably connected to the multiple third guide grooves 442 in a one-to-one manner, and the second end of each driving arm is connected to a positioning member 430, which respectively abuts against different circumferential areas of the side enclosure 14b; along the first extension direction, the rate of decrease of the radial distance between the driving strip segment 201c of the first linkage structure 200 and the central area 20a is the first rate, and the rate of decrease of the radial distance between the driving strip segment 201c of the third linkage structure 400 and the central area 20a is the third rate, and the third rate is greater than the first rate.
[0136] The third guide member 440 may specifically include a third sleeve portion, and a plurality of third extension arms 441 extending radially are provided on the outer periphery of the third sleeve portion, and each third extension arm 441 is provided with a third guide groove 442 along its extension direction; wherein the third sleeve portion may specifically be rotatably sleeved on the vertical shaft 600 through a bearing to achieve axial relative fixation with the vertical shaft 600, and the third sleeve portion or the third extension arm 441 may specifically be fixedly connected to the guide frame 500 through a connecting arm or detachably fixed to the inner bottom mold 110, so as to achieve relative fixation of the circumferential position of the third guide member 440 and the vertical shaft 600 while ensuring that the rotation of each turntable is not interfered with.
[0137] Among them, the turntable of the third linkage structure 400 is the third turntable 410, and the driving arm is the third driving arm 420. During the assembly stage of the core mold A and the casting and maintenance stage after the mold is closed with the outer mold B, multiple third driving arms 420 are outwardly abutted against different positions of the side enclosure 14b through the positioning parts 430, thereby enhancing the strength and stability of the side enclosure 14b, especially reducing the inward pressure exerted on the side enclosure 14b by the material in the casting cavity 800 during the construction and maintenance stages, causing the corner mold 120 and the inner mold 130 to deform inwardly and shift, etc., resulting in a gap between the two, so that the material leaks into the core mold A through the gap, thereby affecting the molding effect of the prefabricated room and damaging the core mold A.
[0138] The strip holes 20c of the third linkage structure 400 and the first linkage structure 200 only include the driving strip segments 201c, and the extension areas of the driving strip segments 201c of the two are consistent along the circumferential direction; when the core mold A is opened, the vertical shaft 600 is driven to rotate to drive the first turntable 230, the second turntable 330 and the third turntable 410 to rotate synchronously therewith. In the first stage, as the first turntable 230, the second turntable 330 and the third turntable 410 rotate, the radial distances between the driving strip segments 201c and the central area 20a in the first linkage structure 200 and the third linkage structure 400 are gradually reduced, and the radial distance between the driving strip segments 201c and the central area 20a in the third linkage structure 400 is reduced at a relatively high rate. Large, accordingly, the third driving arm 420 drives the positioning member 430 to withdraw from the side enclosure 14b toward the central area 20a at a relatively large rate, so as to disengage from the abutment and pushing effect of the diagonal mold 120 and the inner mold 130, and reduce the interference of the positioning member 430 on the mold opening operation of the diagonal mold 120 and the inner mold 130; at the same time, the first driving arm 240 pulls each corner mold 120 to gradually disengage from the inner mold 130 and move toward the central area 20a, and the movement rate is lower than the movement rate of the positioning member 430, thereby realizing the synchronous mold opening of multiple corner molds 120 and ensuring the smooth mold opening; in the second linkage structure 300, the positions of the second driving arm 340 and the plug-in protrusion 14d remain stationary, and the position of the inner mold 130 remains different accordingly.
[0139] Continuing, entering the second stage, with the rotation of the first turntable 230, the second turntable 330 and the third turntable 410, the positioning member 430 is driven by the third driving arm 420 to approach the central area 20a of the third turntable 410 at a higher rate, and the corner mold 120 is located on the outside of the positioning member 430 and is driven by the first driving arm 240 to approach the central area 20a of the first turntable 230 at a lower rate; in the second linkage structure 300, the plug-in protrusion 14d enters the driving strip segment 201c from the follower arc segment 202c, and the inner mold 130 remains on the outside of the corner mold 120, and is driven by the second driving arm 340 to gradually approach the central area 20a of the second turntable 330, thereby realizing the synchronous mold opening of multiple inner molds 130 and the prefabricated room, and ensuring the smooth mold opening.
[0140] In this embodiment, the third guide grooves 442 correspond to multiple corner molds 120 one by one, and the third guide grooves 442 are respectively parallel to the side end surfaces 14a of the corresponding corner molds 120; the connection between the adjacent corner molds 120 and the inner molds 130 is provided with a plug-in groove 14c, the positioning member 430 includes a cross arm 431 fixed to the corresponding driving arm, and plug-in arms 432 are provided at both ends of the cross arm 431, and the two plug-in arms 432 are plugged into the plug-in grooves 14c on both sides of the corresponding corner molds 120 one by one. The third guide groove 442, the first guide arm 520 and the first guide groove 252 are all corresponding to each other and arranged in parallel. When the core mold A is in the assembled state, each third driving arm 420 drives the two plug-in arms 432 through the cross arm 431 to be respectively plugged into the plug-in grooves 14c on both sides of the corner mold 120, thereby abutting and limiting the two sides of the corner mold 120 and the two adjacent inner molds 130 toward one side of the corner mold 120. Accordingly, a plurality of positioning members 430 can abut and limit the joints on both sides of all corner molds 120 and inner molds 130, thereby effectively ensuring the positional firmness and stability of all corner molds 120 and inner molds 130, and further ensuring the effectiveness of the corner molds 120 and inner molds 130 during the casting and curing stages.
[0141] In this embodiment, Fig.13 As shown, there are multiple linkage units 20A, and the multiple linkage units 20A are arranged at intervals along the axial direction of the vertical axis 600. During the pouring and curing process, the first driving arms 240 of the multiple groups of first linkage structures 200 can support different vertical positions of the corner mold 120, the second driving arms 340 of the multiple groups of second linkage structures 300 can support different vertical positions of the inner mold 130, and the third driving arms 420 and positioning members 430 of the multiple groups of third linkage structures 400 can support different vertical positions of the corner mold 120 and the inner mold 130, thereby improving the strength and stability of the corner mold 120 and the inner mold 130, and ensuring the effectiveness of the core mold A during the pouring process; when opening the mold, the first driving arms 240 of the multiple groups of first linkage structures 200 can apply a pulling effect to different vertical positions of the corner mold 120, and the second driving arms 340 of the multiple groups of second linkage structures 300 can apply a pulling effect to different vertical positions of the inner mold 130, thereby further improving the stability of the synchronous mold opening of the corner mold 120 and the inner mold 130 by each linkage structure, and ensuring the stability of the mold opening process and the assembly process of the core mold A.
[0142] In this embodiment, for the connecting rod-shaped core mold A and the rotating disk-shaped core mold A, as shown in FIG. Fig.13As shown, the corner mold 120 has a first side extension rib 121 extending inwardly at the edge of its side end surface 14a, and one side rib surface of the first side extension rib 121 is coplanar with the side end surface 14a of the corner mold 120; the inner mold 130 has a second side extension rib 132 extending inwardly at the edge of its side end surface 14a, and one side rib surface of the second side extension rib 132 is coplanar with the side end surface 14a of the inner mold 130. For the core mold A in the form of a rotating disk, the insertion groove 14c can be provided on the adjacent first side extension rib 121 and second side extension rib 132. The arrangement of the first side extension rib 121 and the second side extension rib 132, on the one hand, can effectively increase the fitting area of the corner mold 120 and the inner mold 130 on the basis of ensuring that the corner mold 120 can move relative to the inner mold 130 along the extension direction of its side end surface 14a to realize the opening and closing operation, so as to further reduce the occurrence of material leakage from between the corner mold 120 and the inner mold 130 during the casting process; on the other hand, the first side extension rib 121 and the second side extension rib 132 can play a role in the corner mold 120 and the inner mold 130 during the casting process. On the other hand, for the core mold A in the form of a turntable, the plug-in groove 14c is provided on the first side extension rib 121 and the second side extension rib 132. On the basis of ensuring that the plug-in groove 14c cooperates with the plug-in arm 432 for the plug-in limit, the setting of the plug-in groove 14c can reduce the damage to the corner mold 120 and the inner mold 130 and cause leakage thereof.
[0143] In this embodiment, for the connecting rod-shaped core mold A and the rotating disk-shaped core mold A, as shown in FIG. Fig.18 As shown, the top edge of the inner bottom mold 110 is surrounded by a first annular boss 113, the edge of the first annular boss 113 is surrounded by a second annular boss 114, 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 both provided with plug-in protrusions 14d, and the annular plug-in platforms formed by the plug-in protrusions 14d are fitted and 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 15e.

[0144] Specifically, Fig.18As shown, the inner bottom mold 110 includes a plurality of splicing bodies 116, the side splicing surfaces 116a of adjacent splicing bodies 116 are inclined surfaces, and the splicing bodies 116 have top extension ribs 116b extending upward from the edges of the side splicing surfaces 116a, and the rib surface of the splicing side of the top extension rib 116b is coplanar with the side splicing surface 116a.
