[0023] The following is for reference. Figures 1 to 6 This invention describes a prefabricated window sill forming mold according to an embodiment of the present invention.

[0024] According to the prefabricated window sill forming mold of the present utility model embodiment, refer to Figures 1 to 6 As shown, a precast window sill 600 is formed by pouring concrete. The precast window sill 600 can be a precast bay window. The precast window sill forming mold includes a base 100, an outer ring mold 200, an inner mold 300, and two auxiliary molds 400.

[0025] Among them, reference Figures 1 to 3As shown, the annular outer mold 200 is connected to the top of the base 100. The annular outer mold 200 can be in the form of a square frame. The annular outer mold 200 has a first side mold 201 on both sides along the first direction and a second side mold 202 on both sides along the second direction. The first direction is perpendicular to the second direction, and both the first direction and the second direction can be horizontal.

[0026] refer to Figures 1 to 4 As shown, the inner mold 300 is connected to the top of the base 100 and located inside the annular outer mold 200. The inner mold 300 can also be roughly square in shape. A casting cavity 500 is formed between the inner mold 300 and the annular outer mold 200. The casting cavity 500 can be roughly annular. For example, the inner mold 300 can have a third side mold 301 on both sides along the second direction, and a fourth side mold 302 on both sides along the first direction. A first casting cavity is defined between the second side mold 202 and the adjacent third side mold 301. The two first casting cavities are used to cast the two side frames 601 of the precast window sill 600. A second casting cavity is defined between the first side mold 201 and the adjacent fourth side mold 302. The two second casting cavities are used to cast the bottom frame 602 and the top frame 603 of the precast window sill 600. The two first casting cavities and the two second casting cavities are connected end to end to form the casting cavity 500.

[0027] refer to Figures 1 to 4 As shown, two auxiliary molds 400 are disposed within the casting cavity 500 and are located on both sides of the inner mold 300 along the first direction, respectively, meaning they can be located within two second casting cavities. There is a gap between the auxiliary molds 400 and the inner mold 300. The gap between the inner mold 300 and one of the auxiliary molds 400 is used to form the first horizontal plate 604 on the top frame 603, and the gap between the inner mold 300 and the other auxiliary mold 400 is used to form the second horizontal plate 605 on the bottom frame 602. There is a gap between the two ends of the auxiliary molds 400 along the second direction and the second side molds 202. This gap is used to form the upwardly projecting portion of the side frame 601 protruding from the first horizontal plate 604 or the downwardly projecting portion of the side frame 601 protruding from the second horizontal plate 605. The side of the auxiliary mold 400 away from the inner mold 300 is attached to the first side mold 201. The bottom end of the auxiliary mold 400 has a first bottom surface 401 and two second bottom surfaces 402. The two second bottom surfaces 402 are located at both ends of the first bottom surface 401 along the second direction. The first bottom surface 401 is attached to the top surface of the base 100. The two second bottom surfaces 402 are higher than the base 100 and form a first molding cavity 501 between them and the top surface of the base 100.

[0028] In this application, concrete is injected into the casting cavity 500. The concrete on both sides of the casting cavity 500 along the second direction is used to form the two side frames 601 of the precast window sill 600, and the concrete on both sides of the casting cavity 500 along the first direction is used to form the top frame 603 and the bottom frame 602 of the precast window sill 600. The two auxiliary molds 400 can form two mounting grooves 606 on the top frame 603 and the bottom frame 602. Since the side of the auxiliary mold 400 away from the inner mold 300 is attached to the first side mold 201, the top of the mounting groove 606 on the top frame 603 can be open, and the top of the mounting groove 606 on the bottom frame 602 can be open. The bottom of the 6 is open. In addition, since the first bottom surface 401 of the auxiliary mold 400 is attached to the top surface of the base 100, and the second bottom surface 402 of the auxiliary mold 400 at both ends of the first bottom surface 401 is higher than the base 100 and forms a first molding cavity 501 between it and the top surface of the base 100, a blocking structure 607 can be formed at both ends of the outer side of the placement groove 606, and an opening can be formed between the two blocking structures 607. This not only makes it convenient to place objects such as the outdoor unit of the air conditioner in the placement groove 606, but also the two blocking structures 607 can protect the outdoor unit of the air conditioner and other objects to prevent them from falling, thus improving safety.

[0029] refer to Figures 1 to 6 As shown, in some embodiments of this utility model, the auxiliary mold 400 includes a main body 403 and two molding parts 404. The main body 403 is connected to the top of the base 100 and / or the first side mold 201. The bottom surface of the main body 403 forms a first bottom surface 401. The two molding parts 404 are detachably disposed at both ends of the main body 403 along a second direction, and the bottom surface of the molding parts 404 forms a second bottom surface 402. For example, the main body 403 can be connected to the top of the base 100 or to the first side mold 201. The molding parts 404 can be detachably connected to the first side mold 201 and / or the main body 403.

[0030] In this embodiment, when the precast window sill 600 needs to be demolded after casting, the molding part 404 can be disassembled and moved upwards out of the precast window sill 600. This allows the molding part 404 to be moved out together with the precast window sill 600. Then, the molding part 404 can be separated from the precast window sill 600, avoiding interference with the removal of the precast window sill 600 because the molding part 404 is located directly above the blocking structure 607. This makes demolding of the precast window sill 600 more convenient.

[0031] refer to Figure 5 As shown, in some embodiments of this utility model, the molding part 404 is detachably connected to the first side mold 201. Since the side of the molding part 404 facing away from the inner mold 300 is attached to the first side mold 201, the molding part 404 and the first side mold 201 are detachably connected, making connection and disassembly more convenient.

[0032] refer to Figure 5 As shown, in some embodiments of this utility model, the molding part 404 is provided with a plurality of first nuts 405, the first side mold 201 is provided with a plurality of corresponding second nuts 203, the second nuts 203 are coaxial with the corresponding first nuts 405, and a first bolt 204 is installed between the second nuts 203 and the corresponding first nuts 405. The first bolt 204 can be a hand-tightening bolt.

[0033] In this embodiment, multiple first nuts 405 are pre-welded or pre-embedded in the molding part 404, and multiple corresponding second nuts 203 are pre-welded or pre-embedded in the first side mold 201. When connecting the molding part 404 to the first side mold 201, it is only necessary to make the second nuts 203 coaxial with the corresponding first nuts 405, and then install the first bolt 204 between the second nuts 203 and the corresponding first nuts 405. The operation is simple and convenient, and the resistance encountered when tightening the first bolt 204 is small, making tightening easier, and thus making assembly and disassembly easier. In addition, the setting of first nuts 405 and second nuts 203 makes the connection strength high and the connection more stable.

[0034] refer to Figure 5 As shown, in some embodiments of this utility model, both the molding part 404 and the first side mold 201 are hollow structures. The first nut 405 is welded to the inner wall of the molding part 404 near the first side mold 201, and the second nut 203 is welded to the inner wall of the first side mold 201 near the molding part 404. The side wall of the first side mold 201 away from the molding part 404 is provided with a first operating port 205. Both the molding part 404 and the first side mold 201 can be assembled from multiple plates. Before assembly, the first nut 405 and the second nut 203 are welded to the corresponding plates, and through holes for the first bolt 204 to pass through can be opened on the corresponding plates.

[0035] In this embodiment, the first nut 405 and the second nut 203 are located in the inner cavities of the forming part 404 and the first side mold 201, respectively, which can prevent the first nut 405 and the second nut 203 from affecting the forming of the precast window sill 600. The side wall of the first side mold 201 away from the forming part 404 is provided with a first operating port 205, which makes it convenient for the operator to insert their hand through the first operating port 205 into the inner cavity of the first side mold 201 to tighten the first bolt 204, making it more convenient to use.

[0036] refer to Figure 6 As shown, in some embodiments of this utility model, the molding part 404 is detachably connected to the body part 403. Since the molding part 404 fits against the end of the body part 403 along the second direction, the molding part 404 and the body part 403 are detachably connected, making connection and disassembly more convenient.

[0037] It should be noted that the molding part 404 can be detachably connected to both the main body part 403 and the first side mold 201 at the same time, or it can be detachably connected to only one of the main body part 403 and the first side mold 201.

[0038] refer to Figure 6 As shown, in some embodiments of this utility model, the forming part 404 is provided with a plurality of third nuts 406, and the main body part 403 is provided with a plurality of corresponding fourth nuts 407. The fourth nuts 407 are coaxial with the corresponding third nuts 406 and are equipped with second bolts 408.

[0039] In this embodiment, multiple third nuts 406 are pre-welded or pre-embedded in the forming part 404, and multiple corresponding fourth nuts 407 are welded or pre-embedded in the body part 403. When connecting the forming part 404 to the body part 403, it is only necessary to make the third nuts 406 and the corresponding fourth nuts 407 coaxial, and then install the second bolt 408 between the third nuts 406 and the corresponding fourth nuts 407. The operation is simple and convenient, and the resistance encountered when tightening the second bolt 408 is small, making tightening easier, and thus making assembly and disassembly easier. In addition, the setting of third nuts 406 and fourth nuts 407 makes the connection strength high and the connection more stable.

[0040] refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, both first side molds 201 are provided with weight reduction openings 206, the weight reduction openings 206 penetrate through the first side molds 201 along the first direction, and the main body 403 covers the side of the weight reduction openings 206 near the main body 403.

[0041] In this embodiment, since the side of the auxiliary mold 400 away from the inner mold 300 is attached to the first side mold 201, a weight-reducing opening 206 can be opened on the outside of the main body 403 of the first side mold 201. The main body 403 can cover the side of the weight-reducing opening 206 near the main body 403. In this way, not only can materials be saved and the overall weight of the mold be reduced, but also the covering effect of the main body 403 can prevent concrete from flowing out of the weight-reducing opening 206.

[0042] refer to Figure 6As shown, in some embodiments of this utility model, both the molding part 404 and the body part 403 are hollow structures. The third nut 406 is welded to the inner wall of the molding part 404 near the body part 403, and the fourth nut 407 is welded to the inner wall of the body part 403 near the molding part 404. The side wall of the body part 403 away from the inner mold 300 is provided with a second operating port 409, which at least partially overlaps with the projection of the weight reduction port 206 in the first direction. Both the molding part 404 and the body part 403 can be assembled from multiple plates. Before assembly, the third nut 406 and the fourth nut 407 are welded to the corresponding plates, and through holes for the second bolt 408 to pass through can be opened on the corresponding plates.

[0043] In this embodiment, the third nut 406 and the fourth nut 407 are located in the inner cavities of the molding part 404 and the main body part 403, respectively, which can prevent the third nut 406 and the fourth nut 407 from affecting the molding of the precast windowsill 600. A second operating port 409 is provided on the side wall of the main body part 403 away from the inner mold 300. The second operating port 409 and the projection of the weight reduction port 206 in the first direction at least partially overlap, which makes it convenient for the operator to pass through the weight reduction port 206 and the second operating port 409 to reach into the inner cavity of the main body part 403 to tighten the second bolt 408, making it more convenient to use.

[0044] refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the top of the auxiliary mold 400 is lower than the top of the casting cavity 500. Thus, the area of ​​the casting cavity 500 above the auxiliary mold 400 can be used to form the back plate 608 of the top frame 603 and bottom frame 602 of the precast window sill 600. After the precast window sill 600 is installed, the back plate 608 is vertically positioned and connected to either the first horizontal plate 604 or the second horizontal plate 605. The back plate 608 and the blocking structure 607 are located on opposite sides of the mounting groove 606, and both ends of the back plate 608 are connected to the two side frames 601. Forming the back plate 608 not only makes it easier to define the mounting groove 606 but also makes the installation of the precast window sill 600 more convenient.

[0045] refer to Figure 1 and Figure 4As shown, in some embodiments of this utility model, the inner mold 300 is detachably connected to the base 100. The inner mold 300 has third side molds 301 on both sides along the second direction. The bottom ends of the two third side molds 301 are recessed in opposite directions to form second molding cavities. The second molding cavities are used to form limiting plates 609 on the outer edges of the two adjacent side frames 601 of the precast window sill 600, thus making window installation more convenient. The inner mold 300 is detachably connected to the base 100, for example, by fasteners. Thus, when the precast window sill 600 needs to be demolded after casting, the inner mold 300 can be removed first. This avoids interference between the third side molds 301 of the inner mold 300 and the limiting plates 609 of the precast window sill 600, which would affect the demolding of the precast window sill 600.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
