Description

Technical Field

[0001] This utility model belongs to the field of precast component mold technology, specifically relating to a precast concrete component mold that is easy to demold. Background Technology

[0002] In the construction and engineering field, precast concrete components are parts that are prefabricated in a factory or other production site and then transported to the site for assembly and installation. These components can include precast concrete elements of various shapes and sizes, such as wall panels, beams, columns, and stairs. Because concrete components come in a wide variety of shapes and sizes, custom molds are required to ensure the precise manufacture of the components.

[0003] Existing precast component molds primarily rely on manual tapping of the outside of the mold to vibrate and separate the precast component from the inner wall. However, manual tapping has significant drawbacks. The tapping force depends entirely on the operator's experience; insufficient force leads to incomplete demolding, requiring repeated attempts, while excessive force can cause dents or deformation on the mold surface, or even damage to the edges of the precast component, affecting the finished product's pass rate. Therefore, a more efficient precast concrete component mold is needed to address this issue. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concrete precast component mold that is easy to demold. The automatic boxing uses uniform vibration to assist the separation of the precast component from the inner wall of the mold. Compared with manual knocking, this design can control the knocking frequency and force, avoid damage to the mold or component due to improper force, and improve the controllability of the demolding process.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a precast concrete component mold that is easy to demold. The precast concrete component mold includes a mold body, which is semi-cylindrical. Two mold bodies are provided and are hinged and fixed between them by a hinge seat. A first protruding seat is provided on the side of the mold body away from the hinge seat. A positioning cavity is provided on the first protruding seat, and a fixing component for auxiliary fixing is installed in the positioning cavity.

[0008] The two mold bodies are cylindrical and mounted on the top of the base. A second protruding seat is provided on the side of the base, and a third protruding seat is provided on the side of the mold body. The second protruding seat and the third protruding seat are connected and fixed by a fixing component. An inner liner is provided at the center of the mold body.

[0009] Furthermore, the fixing assembly includes a lead screw hinged to a first protrusion, a sleeve sleeved on the lead screw, the lead screw and the sleeve being threadedly engaged, and a fixing handle fixed on the outer side of the sleeve.

[0010] Furthermore, the liner is cylindrical in shape and is composed of four semi-circular fixing pieces, which are fixed by bolts.

[0011] Furthermore, a striking assembly is installed on the outer side of the mold body. The striking assembly includes a fixed plate fixed to the outer side of the mold body, a fixed cylinder fixed to the outer side of the fixed plate, a striking cylinder slidably mounted on the fixed cylinder, a striking port for the striking cylinder to slide on the fixed plate, a rotating column passing through the striking cylinder, an elliptical transmission groove on the outer side of the rotating column, a slider on the inner side of the striking cylinder, and the sliding between the transmission groove and the slider. A servo motor for driving the rotating column to rotate is installed on the outer side of the fixed cylinder.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a striking component. The striking component, located on the outside of the mold, is fixed to the side of the mold body by a fixing plate and fixing plate bolts. During demolding, a servo motor drives the rotating column to rotate. The elliptical transmission groove on its outside cooperates with the slider on the inside of the striking cylinder, driving the striking cylinder to slide back and forth in the fixed cylinder. The limiting block and the limiting groove cooperate to ensure the linearity of the sliding, so that the end of the striking cylinder periodically impacts the outside of the mold body. The uniform vibration assists in the separation of the prefabricated component from the inner wall of the mold. Compared with manual striking, this design can control the striking frequency and force, avoid damage to the mold or component due to improper force, and improve the controllability of the demolding process.

[0018] This invention utilizes a fixed assembly. The mold body comprises two semi-cylindrical structures hinged together by a hinge seat, forming a complete cylinder when closed. Combined with the fixed assembly on the first protruding seat, this enables rapid assembly and fixation of the mold. During operation, simply rotating the sleeve on the lead screw, through threaded engagement, causes the sleeve end to press against the first protruding seat on the other side, thus achieving lateral fixation. Simultaneously, the second protruding seat of the base and the third protruding seat of the mold body are connected by another set of fixed assemblies, further enhancing overall stability. This design reduces the cumbersome steps of traditional bolt fixing, significantly improving mold assembly efficiency. Furthermore, the hinged structure prevents component loss and enhances ease of use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a mold for easy demolding of precast concrete components, such as... Figure 1-4 As shown, the easy-to-demold precast concrete component mold includes a mold body 1, which is semi-cylindrical. There are two mold bodies 1, which are hinged and fixed together by a hinge seat 2. The two mold bodies 1 are cylindrical and are mounted on the top of the base 3. An inner liner 31 is provided at the center of the mold body 1. The inner liner 31 is cylindrical in shape and is composed of four semi-circular fixing pieces. The inner liner 31 is fixed by bolts.

[0027] A second protruding seat 9 is provided on the side of the base 3, and a third protruding seat 10 is provided on the side of the mold body 1. The second protruding seat 9 and the third protruding seat 10 are connected and fixed by a fixing component 5. A first protruding seat 4 is provided on the side of the mold body 1 away from the hinge seat 2. A positioning cavity is provided on the first protruding seat 4. A fixing component 5 for auxiliary fixing is installed in the positioning cavity. The fixing component 5 includes a screw 6 hinged to a first protruding seat 4. A sleeve 7 is sleeved on the screw 6. The screw 6 and the sleeve 7 are threaded together. A fixing handle 8 is fixed on the outer side of the sleeve 7. The screw 6 is installed on the second protruding seat 9.

[0028] With the fixed component 5, the mold body 1 adopts two semi-cylindrical structures and is hinged together by the hinge seat 2. When closed, they form a complete cylinder. Together with the fixed component 5 on the first protrusion seat 4, the mold can be quickly assembled and fixed. During operation, simply rotate the sleeve 7 on the screw 6, and the end of the sleeve 7 will press against the first protrusion seat 4 on the other side through the threaded engagement to complete the lateral fixation. At the same time, the second protrusion seat 9 of the base 3 and the third protrusion seat 10 of the mold body 1 are connected by another set of fixed components 5, further enhancing the overall stability. This design reduces the cumbersome steps of traditional bolt fixing, significantly improves the assembly efficiency of the mold, and the hinged structure avoids the loss of parts, improving the convenience of use.

[0029] A striking assembly 11 is installed on the outer side of the mold body 1. The striking assembly 11 includes a fixed plate 12 fixed on the outer side of the mold body 1. A fixed plate is fixedly fixed on the side of the fixed plate 12. The fixed plate is fixed to the side of the mold body 1 by bolts. A fixed cylinder 14 is fixed on the outer side of the fixed plate 12. A striking cylinder 13 is slidably mounted on the fixed cylinder 14. A protective pad is embedded on the outer side of the striking cylinder 13. The side of the striking cylinder 13 facing the mold body 1 is rounded. A striking port 121 for the striking cylinder 13 to slide is opened on the fixed plate 12. A rotating column 15 is installed through the striking cylinder 13. An elliptical transmission groove is opened on the outer side of the rotating column 15. A slider is provided on the inner side of the striking cylinder 13. The transmission groove and the slider slide together. A servo motor 16 for driving the rotating column 15 to rotate is installed on the outer side of the fixed cylinder 14.

[0030] The striking component 11, which is set on the outside of the mold, is fixed to the side of the mold body 1 by the fixing plate 12 and the fixing plate bolts. During demolding, the servo motor 16 drives the rotating column 15 to rotate. The elliptical transmission groove on its outside cooperates with the slider on the inside of the striking cylinder 13, driving the striking cylinder 13 to slide back and forth in the fixing cylinder 14. The limiting block 131 cooperates with the limiting groove 141 to ensure the linearity of the sliding, so that the end of the striking cylinder 13 periodically hits the outside of the mold body 1. The uniform vibration assists the prefabricated component to separate from the inner wall of the mold. Compared with manual striking, this design can control the striking frequency and force, avoid damage to the mold or component due to improper force, and improve the controllability of the demolding process.

[0031] Furthermore, a limiting groove 141 is provided on the inner side of the fixed cylinder 14, and a limiting block 131 is provided on the outer side of the striking cylinder 13. The limiting block 131 and the limiting groove 141 slide together.

[0032] By cooperating with the limiting groove 141 on the inner side of the fixed cylinder 14 and the limiting block 131 on the outer side of the striking cylinder 13, the rotational freedom of the striking cylinder 13 is effectively restricted, ensuring that it only slides back and forth along the axial direction, avoiding the deviation of the striking direction caused by rotation, ensuring that the striking force is accurately applied to the outer side of the mold, and improving the effect and stability of the striking demolding.

[0033] Working principle:

[0034] Two semi-cylindrical mold bodies 1 are hinged together by hinge seats 2. When closed, they form a cylindrical structure and are supported on the top of the base 3. When closed, the first protrusion 4 on the side of the mold body 1 away from the hinge seat 2 is fixed by the fixing component 5. The screw 6 is hinged to one of the first protrusions 4. The sleeve 7 is rotated to make it threaded with the screw 6 until the end of the sleeve 7 abuts against the other first protrusion 4, thus completing the lateral fixation. At the same time, the second protrusion 9 on the side of the base 3 and the third protrusion 10 on the side of the mold body 1 are connected by another set of fixing components 5 to further enhance the overall stability and ensure that the mold structure is stable during casting.

[0035] The inner liner 31, located at the center of the mold body 1, is composed of four semi-circular fixing pieces, which are fixed by bolts to form a cylindrical structure that fits against the inner wall of the mold. The split design of the inner liner 31 allows for quick disassembly during demolding, reducing the adhesion resistance between the prefabricated components and the inner wall of the mold, and facilitating component demolding.

[0036] The striking component 11, located on the outer side of the mold, is fixed to the side of the mold body 1 by a fixing plate 12 and fixing plate bolts. During demolding, the servo motor 16 starts, driving the rotating column 15 to rotate. The elliptical transmission groove on the outer side of the rotating column 15 cooperates with the slider on the inner side of the striking cylinder 13, driving the striking cylinder 13 to slide back and forth in the fixing cylinder 14. The limiting block 131 cooperates with the limiting groove 141 to ensure the linearity of the sliding, so that the end of the striking cylinder 13 periodically impacts the outer side of the mold body 1. The vibration assists in separating the prefabricated component from the inner wall of the mold, reducing the difficulty of demolding.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
