Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for a rail-top air duct prefabricated component with a quick-release structure. Background Technology

[0002] The track-top ventilation duct, also known as the train-top exhaust duct, is an important internal structural component of the subway station ventilation system. It is suspended at the junction of the station's central slab and the structural side walls. Due to its special location, it is generally not poured simultaneously with the main station structure. Track-top ventilation ducts are divided into cast-in-place reinforced concrete track-top ventilation ducts and precast ducts. Precast track-top ventilation ducts are prefabricated off-site using molds, which effectively ensures structural quality. On-site assembly eliminates the need for formwork, reducing construction difficulty and manpower requirements, saving economic costs, and aligning with modern green and environmentally friendly construction concepts. Currently, precast track-top ventilation duct production often uses box-type molds, requiring cranes to dismantle the molds and lift the track-top ventilation duct product, making operation complex and inconvenient.

Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides a mold for prefabricated components of a rail-top air duct with a quick-release structure, such as... Figure 1-6 As shown, it includes an outer mold frame 101, a side mold frame 102 connected to the outer mold frame 101, and an inner mold assembly 103 disposed inside the side mold frame 102. The inner mold assembly 103 includes a detachable first inner mold frame 104 and a detachable second inner mold frame 105 disposed below the first inner mold frame 104. The outer mold frame 101 includes a base plate 106, a first outer mold frame 107 fixed on the base plate 106, and a second outer mold frame 108 connected to the base plate 106.

[0029] The outer mold frame 101 of this embodiment includes a base plate 106 and a first outer mold frame 107 and a second outer mold frame 108 arranged opposite to each other. The first outer mold frame 107 is fixed to one side of the base plate 106, and the second outer mold frame 108 can be fixed to the other side of the base plate 106, or it can be set as a separable type for easy demolding. A structure to enhance stability can be added between the base plate 106 and the first outer mold frame 107, such as a connecting plate or a connecting steel frame, to improve the firmness and stability of the base plate 106 and the first outer mold frame 107. There are at least two side mold frames 102, which are respectively set on the two adjacent sides of the first outer mold frame 107 and the second outer mold frame 108. In this embodiment, the base plate 106, the first outer mold frame 107, the second outer mold frame 108 and the side mold frames 102 together form the outer frame of the mold. The connection between the side mold frames 102 and the outer mold frame 101 can be such that the side mold frames 102 can be completely disassembled, or it can be movably connected to the outer mold frame 101. The separable structure facilitates the subsequent demolding of the product. The fixing methods of each side mold frame 102 can be different. To facilitate demolding, both the first inner mold frame 104 and the second inner mold frame 105 are detachable. The first inner mold frame 104 and the second inner mold frame 105 have different sizes to improve the continuity of the molding cavity. The first inner mold frame 104 and the second inner mold frame 105 are connected and fixed to the outer mold frame 101 or the side mold frame 102 by a fastening structure. In this embodiment, the first inner mold frame 104 has a U-shaped structure, and the second inner mold frame 105 is connected to the first inner mold frame 104. The outer ends of both abut against one side of the side mold frame 102. The inner mold assembly 103, the outer mold frame 101, and the side mold frame 102 are connected and fixed together by a fastening structure to form the molding cavity of the mold. The molding material is directly injected into the molding cavity from above. The top of the mold can be set with a top structure according to the actual product shape. In this embodiment, the top of the product is flat, so there is no need to add a top structure. This increases the area of ​​the pouring gate and facilitates the increase of the injection speed.

[0030] In some embodiments, such as Figure 1-2 As shown, the side mold frame 102 is rotatably connected to one side of the outer mold frame 101 through the first rotating structure 2.

[0031] The first rotating structure 2 can be a hinge, a rotating shaft, or other rotating structures that allow the side mold frame 102 and the outer mold frame 101 to rotate. The side mold frame 102 can be rotatably connected to the first outer mold frame 107 or to the base plate 106. If the mold has a top structure, it can also be rotatably connected to the top structure. In this embodiment, the side mold frame 102 is connected to the first outer mold frame 107. A connection structure to strengthen stability can be added to the side mold frame 102 to improve the stability between it and the first outer mold frame 107.

[0032] In some embodiments, such as Figure 2As shown, the second outer mold frame 108 generates relative displacement with the base plate 106 through the sliding structure 3.

[0033] The sliding structure 3 separates the second outer mold frame 108 from the base plate 106. In this embodiment, the sliding structure 3 is a transverse rod set on the second outer mold frame 108, and the base plate 106 is provided with a transverse groove that matches the transverse rod. The sliding structure 3 can also be a rolling structure such as rollers set on the second outer mold frame 108, and a track that cooperates with the rolling structure on one side of the base plate 106. The sliding structure 3 can also be a combination of pulleys on the second outer mold frame 108 and a slide rail on one side of the base plate 106. The sliding structure 3 facilitates product demolding.

[0034] In some embodiments, such as Figure 1-4 As shown, a first quick-release structure 4 is provided on one side of the side mold frame 102.

[0035] Unlike traditional fastening structures such as bolts and nuts, the first quick-release structure 4 can be disassembled quickly without the need to separate the parts, thus preventing loss. The first quick-release structure 4 can effectively improve the speed of mold closing and opening, thereby increasing the production speed. The first quick-release structure 4 of the side mold frame 102 can be used to connect the side mold frame 102 and the inner mold assembly 103, and can also be used to connect the side mold frame 102 and the outer mold frame 101.

[0036] Furthermore, such as Figure 1-4 As shown, the first quick-release structure 4 includes a connecting structure 401, a first hinge structure 402 disposed at one end of the connecting structure 401, and an adjustable first fixing structure 403 disposed at the other end of the connecting structure 401 for clamping.

[0037] The connecting structure 401 is used to connect two mold frames that need to be fixed. In this embodiment, the first quick-release structure 4 is used to connect the first inner mold frame 104 and the side mold frame 102, and the side mold frame 102 and the second outer mold frame 108. Similarly, it can also be used to connect the second inner mold frame 105 and the side mold frame 102, or other structures. The first hinge structure 402 can be provided on the side mold frame 102, or on the inner mold assembly 103 or the outer mold frame 101. The first inner mold frame 104 and the side mold frame 108 are connected by a hinge structure 401. Taking the connection as an example, the connection structure 401 is hinged to one side of the first inner mold frame 104 through the first hinge structure 402. The connection structure 401 is a bridge connecting the first inner mold frame 104 and the side mold frame 102. The first fixing structure 403 at the other end of the connection structure 401 is used to press the first inner mold frame 104 and the side mold frame 102 together. The first fixing structure 403 can be a nut and screw that abut against the side mold frame 102 or a similar adjustment structure. By turning the nut, one end of the nut or screw abuts against the side mold frame 102. In one embodiment, the first hinge structure 402 is mainly used to realize the rotation of the connecting structure 401, and to quickly lock and disassemble by the abutment of the first fixing structure 403 with the side mold frame 102; in another embodiment, the first hinge structure 402 includes one or more hinge structures, and the first quick-release structure 4 can be placed at the dead point position by pulling the hinge component. At this time, the first fixing structure 403 is mainly used for pressing, and its adjustment structure is used to adjust the pressing distance. In this state, no matter how much reaction force the pressed workpiece has, it cannot loosen the first fixing structure 403, so that the first fixing structure 403 can be firmly abutted with the side mold frame 102.

[0038] Furthermore, such as Figure 1-4 As shown, the first hinge structure 402 includes a first base 404 and a first hinge portion 405 that is hinged to the connecting structure 401 and the first base 404 respectively.

[0039] The first base 404 can be set at the required mold frame position. The first base 404 is hinged to the first hinge part 405, and the first hinge part 405 is hinged to the connecting structure 401. By snapping the first hinge part 405, the first fixing structure 403 can be abutted and locked. Specifically, the first hinge part 405 can be provided with a space for convenient insertion of a pry bar or other prying structure, or a protruding structure is provided on one side of the first hinge part 405 for convenient pulling of the first hinge part 405.

[0040] In some embodiments, such as Figure 1-4 As shown, the first fixing structure 403 includes a push rod 406 and an adjusting part 407 that matches the push rod 406 for adjusting the distance of the push rod 406.

[0041] In this embodiment, the adjustment part 407 can adjust the extension distance between the push rod 406 and the connecting structure 401, so as to facilitate a better and tighter contact. The adjustment part 407 can be a protruding structure with internal threads provided on one side of the connecting structure 401, and the push rod 406 is provided with matching threads; the adjustment part 407 can also be a through groove with internal threads provided on the connecting structure 401, and the push rod 406 is directly screwed into the through groove for adjustment; the adjustment part 407 can also be an adjustment structure screwed to the push rod 406, which adjusts the distance between itself and the mold frame and abuts against the mold frame by rotating itself.

[0042] In some embodiments, such as Figure 1 , 5 As shown in Figures 6 and 7, a second quick-release structure 5 is provided on one side of the outer mold frame 101.

[0043] Unlike traditional fastening structures such as bolts and nuts, the second quick-release structure 5 can be disassembled quickly without the need to separate the parts, thus preventing loss. The second quick-release structure 5 can effectively improve the speed of mold closing and opening, thereby increasing production speed. It can be connected in various ways, including connecting the base plate 106 and the side mold frame 102, or connecting the side mold frame 102 and the inner mold assembly 103.

[0044] Furthermore, such as Figure 1 , 5 As shown in Figures 6 and 7, the second quick-release structure 5 includes a second base 501, a second hinge structure 502 hinged to the second base 501, a second rotating structure 503 connected to the second hinge structure 502, a third hinge structure 504 connected to the second rotating structure 503, and a second fixing structure 505 disposed on the third hinge structure 504.

[0045] The second quick-release structure 5 facilitates the secure connection of the outer mold frame 101 to the side mold frame 102 or the inner mold assembly 103. In this embodiment, the base plate 106 and the side mold frame 102 are connected using the second quick-release structure 5. The second base 501 can be located on one side of the base plate 106 or on one side of the side mold frame 102. The second hinge structure 502 is hinged to the second base 501, allowing the lower structure to rotate upwards. The third hinge structure 504 and the second hinge structure 502 have a second rotating structure 503 between them, enabling the third hinge structure 504 and its... The second fixing structure 505, which is subsequently connected, can rotate to increase flexibility. In this embodiment, the second fixing structure 505 consists of protrusions on both sides of the third hinge portion 507. The side mold frame 102 is also provided with a grooved slot structure that matches the second fixing structure 505. The second rotating structure 503 facilitates the entry of the second fixing structure 505 into the groove. The second fixing structure 505 can be a slot structure that engages with the protrusions on the side mold frame 102. The second fixing structure 505 can also be a hook structure and a slot structure, or other matching structures.

[0046] Furthermore, such as Figure 1 , 5 As shown in Figures 6 and 7, the third hinge structure 504 includes a second hinge portion 506 connected to the second rotating structure 503 and a third hinge portion 507 hinged to the second hinge portion 506, and the second fixing structure 505 is disposed on the third hinge portion 507.

[0047] The second hinge 506 facilitates the assembly of the second fixing structure 505 into the corresponding fixing structure. The third hinge 507 allows the second quick-release structure 5 to be in a dead position by snapping the third hinge 507. In this embodiment, the second hinge structure 502 on the base plate 106 is closer to the bottom surface, has a limited range of motion, and is difficult to snap. The third hinge 507 makes the snapping structure on the outside, which is convenient for disassembly and assembly.
