[0001] This invention relates to the field of prefabricated component manufacturing, and in particular to an automatic assembly and disassembly mold for prefabricated component door and window openings. Background Technology

[0002] When manufacturing precast components, the main body of the mold is first assembled, and then concrete is poured into it. After the concrete has solidified, the main body of the mold is removed, and the precast component is obtained. If it is necessary to construct cavities within the precast component, such as cast-in-place areas, modules of corresponding shapes can be set within the main body of the mold. After the concrete is poured, the modules will form the corresponding cavities.

[0003] For precast components with door and window openings, a mold shaped like the door and window openings needs to be set up inside the main mold body during manufacturing.

DETAILED DESCRIPTION

[0042] The principles and spirits of the present application will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that the description of these embodiments is only for the purpose of enabling those skilled in the art to better understand and implement the present application, and does not limit the scope of the present application in any way.

[0043] Please refer to Figures 1-11 The present application provides an automatic assembly and disassembly mold for the door and window hole of a prefabricated component, which comprises a mold main body. The mold main body as a whole comprises four right-angle components 1 arranged in a quadrilateral. Two adjacent right-angle components 1 are connected by a movable assembly 2. The movable assembly 2 can be switched between a support state and a contraction state. In the support state, the two right-angle components 1 on both sides are pried away from each other, and vice versa in the contraction state. In the pried-away state, the shape of the door and window hole of the prefabricated component is formed, which can be placed into the mold of the prefabricated component to be used as a door and window hole module (i.e. including a door module or a window module). After the concrete poured into the prefabricated component mold is solidified, the movable assembly 2 can be controlled to contract, so as to take out the mold main body.

[0044] In the supported state, the movable component 2 supports the right-angled parts 1 on its left and right sides. The mechanical strength of the movable component 2 allows for a rigid connection between adjacent right-angled parts 1. This rigid connection enhances the rigidity and flatness of the mold after assembly. For example, in one embodiment, the movable component 2 includes multiple rigid movable plates connected together by rigid movable shafts. The outermost movable plate is also connected to the right-angled parts 1 by a movable shaft. When the movable component 2 is supported, the movable plates flatten with the help of the movable shafts. At this time, the rigidity of the movable plates and movable shafts achieves a rigid connection between adjacent right-angled parts 1. The materials of the movable plates and movable shafts can be selected according to the actual situation, as long as they can form the above-mentioned rigid connection, including but not limited to various metals, alloys, non-metallic materials, organic materials, and composite materials composed of the above materials.

[0045] In some embodiments, stiffening plates 16 are respectively provided on both sides of the movable component 2. When the mold is supported, the two stiffening plates 16 press against the inner side of the mold panel to form a support, thereby achieving the effect of automatic correction of mold assembly and improving the rigidity and flatness of the mold. Since the supporting action of the stiffening plates on the inner side of the mold is completed synchronously with the supporting and unfolding action of the movable component, the automatic correction of the mold can be achieved at the same time as the supporting action is completed, improving the synchronicity and work efficiency of mold assembly and correction operations.

[0046] A control mechanism is provided inside the mold body, and the control mechanism is connected to each movable component 2 to control them to achieve the above-mentioned support and retraction actions. As an example, the main body of the control mechanism includes a first body 7 and a second body 8 located at the center of the mold body. The two are stacked one above the other and fixed together, and the whole is generally box-shaped. Two transverse guide grooves 9 are arranged horizontally at intervals on the first body 7. Two longitudinal guide grooves 9 are arranged horizontally at intervals on the second body 8. A rack 4 is arranged in each guide groove 9. The ends of the guide grooves 9 extend from both sides of the main body, so that the rack 4 moves and extends in the guide grooves 9 to connect to the support rod 5.

[0047] Thus, the four racks 4 are arranged in two layers along the thickness direction of the mold body, which is also the thickness direction of the door and window openings of the prefabricated components to be produced. Each layer has two racks 4, and these two racks 4 are arranged symmetrically with respect to the center of the mold body and the main body of the mechanism, so as to balance the forces during operation. The racks 4 in the first layer and the racks 4 in the second layer are perpendicular to each other and are not in the same plane. The two racks 4 in the first layer are connected to the upper and lower opposing movable components 2 by means of support rods 5, and the two racks 4 in the second layer are connected to the left and right opposing movable components 2 by means of support rods 5.

[0048] The guide groove 9 is easy to process in the mechanism body, has simple structure, and can guide and support the movement of the rack 4 to improve the stability of the rack 4 in conducting power to the movable assembly 4.

[0049] By adjusting the position of the rack 4 in the mechanism body, it can be applied to the door and window openings with different lengths and widths. For example, when one side of the door and window opening parallel to the rack 4 is longer, the tail end of the rack 4 can be arranged closer to the center of the mechanism body, so that the initial length of the rack 4 is longer. Conversely, when one side of the door and window opening parallel to the rack 4 is shorter, the tail end of the rack 4 can be arranged farther away from the center of the mechanism body, so that the initial length of the rack 4 is shorter. Of course, when one side of the door and window opening parallel to the rack 4 is too long or too short, the appropriate size of the rack 4 and the guide groove 9 can be directly replaced.

[0050] The mechanism body is provided with a driving shaft 6 at the center, and one or more gears 11 are arranged on the driving shaft 6. In this embodiment, one gear 11 is arranged in the gear groove 10. One half of the gear groove 10 is arranged in the first body 7 and is connected with the guide groove 9, and the other half is arranged in the second body 8 and is connected with the guide groove 9 to accommodate the gear 11 after the first body 7 and the second body 8 are combined, and then engaged with the rack 4.

[0051] When the driving shaft 6 is rotated by external equipment, the four racks 4 can be simultaneously moved away from or close to the center of the mold body under the drive of the gear 11, such as counterclockwise rotation of the driving shaft 6, the four racks 4 are simultaneously extended, and clockwise retracted (of course, it can also be set in the opposite direction, that is, counterclockwise retracted, clockwise extended). In this way, the simultaneous support or contraction of the four movable assemblies 2 is realized by the support rod 5, and the rapid assembly and disassembly of the mold body is realized.

[0052] The ratchet wheel 23 and the pawl 24 limiting the rotation of the ratchet wheel 23 are arranged on the driving shaft 6, so that when the driving rack 4 reaches the support state and the mold body is supported, the pawl 24 can be used to limit the rotation of the ratchet wheel 23, and then limit the rotation of the gear 11, prevent it from reversing, and ensure the stability of the mold after being supported.

[0053] Since the driving shaft 6 is located in the center of the mold body in the control mechanism, the four racks 4 need to move synchronously and are distributed in two layers, so they can only be set eccentrically relative to the center of the mold body, and the movable assembly 2 needs to be set in the middle of the two straight-angle components 1 to ensure balanced force on both sides. In this way, the axes of the racks 4 are also eccentric relative to the center of the movable assembly 2, and exist in the thickness direction and length (or width) direction of the mold body. In this way, if the racks 4 directly act on the movable assembly 2 through the support rods 5, the force points will be concentrated at the eccentric position of the movable assembly 2, which may cause uneven force on the movable assembly 2 during disassembly and assembly, resulting in damage.

[0054] To solve this problem, in the present embodiment, each rack 4 is connected to the support rod 5 through a connecting disc 12, which plays a role of "correction", so that the axis of the connected support rod 5 can be aligned with the center of the movable assembly. As an example, the connecting disc 12 has a through connecting hole 13, which is threadedly connected with the support rod 5, and the position of the connecting hole 13 is offset from the center of the connecting disc 12 in both length and width directions, so that the force points are "corrected" in the length and width directions of the mold body to be close to the center of the movable assembly 2. In the present embodiment, the movable assembly 2 is generally symmetrical in structure, so its geometric center is the force balance point.

[0055] With the connecting disc 12, the connection point of the rack 4 and the support rod 5 is corrected to a position substantially overlapping the center of the movable assembly 2, and the axis of the support rod 5 is also aligned with the center of the movable assembly 2 for connection, so that the force balance of the movable assembly 2 can be ensured and the risk of damage can be reduced. In addition, the rack 4 and the support rod 5 constitute a lead screw connection through the connecting disc 12. By adjusting the lead screw, i.e. adjusting the position of the support rod 5 relative to the connecting disc 12 and fixing it through a nut, the size can be finely adjusted to improve the dimensional accuracy of the assembled mold body.

[0056] A bottom support 3 is also provided on one side of the first body 7 or the second body 8 to adjust the height of the entire control mechanism to a suitable height.

[0057] In the present embodiment, the movable assembly 2 includes multiple movable plates 21 connected by a movable shaft 22, so that each movable plate 21 is flat away from the center of the mold body in the support state and is collapsed close to the mold body in the retracted state. For example, the movable plate 21 includes three sections, two sections are connected to the two straight-angle components 1 respectively, and the middle movable plate 21 is generally H-shaped (i.e. the middle one is called the first movable plate, and the two sides are the second movable plate and the third movable plate, the same below). In other embodiments, the three movable plates can also be rectangular plates.

[0058] In some embodiments, the outer end of the movable plate 21 closest to the right-angled component 1 is also connected with a connecting plate 14, which is provided with a plurality of openings. The inner edge of the right-angled component 1 is also provided with openings corresponding in position. After the openings are connected, the connecting plate 14 is connected to the inner edge of the right-angled component 1 by means of screws 18. The advantage of this connection mode is that, compared with destructive connection modes such as welding, the screw connection does not damage the dimensional accuracy and mechanical strength of the movable assembly 2 and the right-angled component 1 during disassembly and assembly, which is conducive to ensuring the overall accuracy and rigidity of the mold body during repeated use, assembly and disassembly.

[0059] In some embodiments, the connecting plate 14 is not directly connected with the right-angled component 1, but is connected with the right-angled component 1 by means of a length adjustment tool 15. The length adjustment tool 15 is so named because it can be set to multiple lengths in advance. When it is necessary to lengthen or shorten the length of one side of the door and window opening to a specific length, the length adjustment tool 15 with the appropriate length can be selected according to the actual situation, thereby improving the flexibility and scalability of the mold in terms of manufacturing size. In one embodiment, the length adjustment tool includes an outer body 151 and an inner body 152 that are staggered with each other and combined together to form a "Z" shape as a whole. The outer body 151 is flush with the outer edge of the mold body to improve the flatness of the mold body. The inner body 152 is provided with openings corresponding in position to the openings on the inner side of the right-angled component 1, so that the two are connected by screws. The connecting plate 14 described above is connected to the inner side of the outer body 151 by screws.

[0060] The bottom of the movable plate 21 is connected with a reinforcing structure to improve the supporting strength in the supporting state.

[0061] Further, the reinforcing structure includes two reinforcing ribs 17 arranged perpendicularly to the rib plate 6, and the supporting rod 5 can be connected at a position between the two reinforcing ribs 17. By means of the reinforcing structure perpendicular to each other, the stability of the supporting structure can be better improved in two directions. The supporting rod 5 can be connected to the movable assembly by means of a connecting sleeve 19 provided with a pin hole, which facilitates the assembly and disassembly of the supporting rod 5.

[0062] In addition, in the manufacture of the mold described above, in order to expand the versatility of the mold, the right-angled component and / or the movable assembly can be designed as standard parts of multiple sizes, so that they can be assembled flexibly to adapt to the manufacture of door and window openings of different sizes.

[0063] In some embodiments, the mold body can be used for prefabricated components with thermal insulation (such as Figure 1 、 7 , 8) and can also be used for prefabricated components without thermal insulation (such as Figure 9), if the insulation layer is provided, the bottom support 3 can be relatively thick, and the top of the mold body is inclined to the side of the insulation layer away from the mold body relative to other parts, forming a beak-like structure (i.e. the drip edge 25), so as to form a drip edge on the constructed door and window opening, preventing rainwater from flowing along the wallboard into the wall.

[0064] In some embodiments, the mold body can be a window mold (such as Figure 1 , 9 ) or a door opening mold (such as Figures 10-11 ). If it is a window mold, it includes the four right-angled components 1 described above, and the adjacent right-angled components 1 are connected by the movable assembly 2 to form a window structure. If it is a door opening mold, there are two right-angled components 1 arranged in axial symmetry, and the longer edges in the height direction form the left and right sides of the door. The bottoms are connected together by the bottom mold 26 of the prefabricated component.

[0065] The specific examples are used in the present application to elaborate the inventive concept in detail, and the above description of the embodiments is only for the purpose of helping to understand the core idea of the present application. It should be pointed out that any obvious modification, equivalent replacement or other improvement made by those skilled in the art without departing from the inventive concept should be included in the protection scope of the present application.
