Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of building material production equipment, and in particular, to a casting mold for ultra-high performance concrete precast components. Background Art

[0002] In the construction field, with the continuous expansion of the scale of construction projects and the increasing requirements for building quality, the application of ultra-high performance concrete precast components is becoming more and more extensive. For the casting of large concrete precast components, large removable plate molds are usually used.

[0003] However, this traditional mold structure has some significant problems. In order to ensure the stability and integrity of the mold during the casting process, it is often necessary to install and reinforce the mold by installing connectors inside the mold. However, this operation requires careful planning by professional technicians to determine the best penetration position of the connector. Even so, in actual construction, due to the limitations of the mold structure and construction conditions, it is often difficult to completely avoid conflicts between the penetration position of the connector and the molding surface of the prefabricated component.

[0004] This results in holes on the surface of precast concrete components after forming, which not only affects the appearance quality of the precast components, but also may weaken their structural strength and durability. These holes can easily become the starting point of cracks during subsequent use, reducing the service life of the precast components. In addition, repairing hole defects also requires additional time and cost, increasing the cost and duration of the entire project. Summary of the invention

[0005] To overcome the above-mentioned defects, the embodiments of the present disclosure provide an ultra-high performance precast concrete component casting mold, which solves the technical problem that the through-type connectors used in the molding molds of the precast concrete components in the related art will affect the structure of the molded concrete components.

[0014] For example, in at least one embodiment of the present disclosure, a casting mold for ultra-high performance concrete precast components is provided, wherein the first slot portion has a first guide slope on one side close to the second slot portion, and the upper side of the third sliding block has a second guide slope, and the molding base plate is configured such that, after sliding downward, the first guide slope slides against the second guide slope and drives the third sliding block to slide horizontally, so that the air hole is connected to the connecting port.

[0015] For example, at least one embodiment of the present disclosure provides a casting mold for an ultra-high performance concrete precast component, further comprising: A second elastic member, wherein one end of the second elastic member acts on the second side plate, and the other end of the second elastic member acts on the third sliding block to provide a force for the third sliding block to slide toward the first slot portion or the second slot portion.

DETAILED DESCRIPTION

[0020] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0021] In order to simplify the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0022] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.

[0023] In the present disclosure, unless otherwise expressly specified and limited, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 to Figure 6 As shown, it shows an ultra-high performance concrete precast component casting mold in one embodiment of the present disclosure, including a first side panel 1; the second side panel 2 is arranged at an angle to the first side panel 1, and the second side panel 2 is slidably arranged on the first side panel 1, and the first side panel 1 and the second side panel 2 are symmetrically arranged in pairs, and a molding space 101 is formed between the two first side panels 1 and the two second side panels 2; the molding bottom plate 3 is lifted and slidably arranged in the molding space 101; the first pushing member 4 is lifted and slidably arranged on the second side panel 2, and the first pushing member 4 is used to push the second side panel 2 in the horizontal direction and support the second side panel 2.

[0027] In this embodiment, the first side plate 1 symmetrically arranged in pairs and the second side plate 2 slidingly arranged determine that the device is a mold for a combined model. In the initial state, a small distance is reserved between the molding base plate 3 and the bottom of the molding space 101. During the pouring process, as the cement slurry is injected, the molding base plate 3 will slide down a small amount. Due to the adsorption effect of the first side plate 1 and the second side plate 2 on the cement slurry, the vertical edges near their bottom edges will attach and stretch a part of the cement slurry in advance, which has the effect of applying the slurry to the edge seal where the cavity may exist in advance, and pre-filling and sealing the edge seal. At the same time, the first push piece 4 is gradually squeezed inward. This action avoids the situation where a gap is generated between the first side plate 1, the second side plate 2 and the molding base plate 3 during the sliding process of the molding base plate 3 and the gradual increase in the internal cement pressure, thereby ensuring the sealing and stability of the mold.

[0028] In general, such a design, on the one hand, can make the assembly and disassembly of the mold more convenient. On the other hand, the initial reserved distance and the sliding action of the molding bottom plate 3, combined with the adsorption of mud by the side plate, effectively pre-fill the cavities that may exist at the edges and seams, thereby improving the sealing performance and overall quality of the prefabricated components. Furthermore, the gradual extrusion of the first push piece 4 ensures that the side plates and the molding bottom plate are tightly fitted during the pouring process, preventing the generation of gaps, avoiding concrete leakage and internal structural defects. The working reliability and stability of the mold are improved, the defective rate of prefabricated components is reduced, and the construction efficiency is also improved, reducing the construction cost.

[0029] In some examples, it also includes a supporting outer frame 5, which has an outer frame bottom wall 501 and an outer frame side wall 502, and the second side plate 2 is used to be placed on the outer frame bottom wall 501; one end of the first connecting rod 6 is hinged to the bottom of the forming base plate 3; the first sliding block 7 is horizontally slidably arranged on the outer frame bottom wall 501, and one end of the first connecting rod 6 is hinged to the first sliding block 7; one end of the second connecting rod 8 is hinged to the first sliding block 7, and the other end is hinged to the first pushing piece 4; one end of the third connecting rod 9 is hinged to the first pushing piece 4; the abutment block 10 abuts against the outer frame side wall 502, and the other end of the third connecting rod 9 is hinged to the abutment block 10, and the forming base plate 3 is configured to, after sliding down, drive the first pushing piece 4 to slide up through the first connecting rod 6, the second connecting rod 8 and the third connecting rod 9 and provide the first pushing piece 4 with a force to move toward the forming space 101.

[0030] In this embodiment, when the molding bottom plate 3 slides down, it drives one end of the first connecting rod 6 hinged thereto to descend. The other end of the first connecting rod 6 pushes the first sliding block 7 to slide in the horizontal direction. The sliding of the first sliding block 7 drives the first pushing member 4 to slide up through the second connecting rod 8. At the same time, the first pushing member 4 pushes the abutting block 10 to abut against the outer frame side wall 502 of the supporting outer frame 5 through the third connecting rod 9.

[0031] Since the device is a mold-jointed external splicing structure, the second side plate 2 is a long strip, and as the total amount of cement inside increases, the second side plate 2 may be slightly deformed, causing the sealing of the internal structure to be affected. In this process, the first push member 4 gradually moves toward the molding space 101, exerting an increasingly greater supporting force on the second side plate 2. In particular, for the second side plate 2 with a longer length, as the total amount of cement inside continues to increase, this supporting force can effectively offset the tendency of the internal pressure to expand the second side plate 2 outward, preventing it from deforming.

[0032] In general, firstly, the structure in this solution can automatically adjust the support force for the second side panel 2 according to the change of the total amount of cement in the molding space 101, realizing intelligent pressure balance adjustment without the need for additional manual monitoring and operation. Secondly, focusing on the second side panel 2 with a longer length, a stable and continuously enhanced shape structural support is provided, which effectively avoids its possible deformation, ensures the sealing of the internal structure of the mold, and ensures that the concrete will not leak during the pouring process, thereby improving the molding quality of the prefabricated components. Furthermore, by maintaining the balance between internal and external pressures, the risk of damage to the mold caused by uneven pressure is significantly reduced. Stable and reliable structural support helps to improve the dimensional accuracy and surface flatness of prefabricated components, enhance the market competitiveness of products, and also provides a strong technical guarantee for the efficient and high-quality production of prefabricated concrete components.

[0033] In some examples, a first elastic member 11 is further included. One end of the first elastic member 11 acts on the molded bottom plate 3 , and the other end of the first elastic member 11 acts on the outer frame bottom wall 501 , providing a force in a direction in which the molded bottom plate 3 moves away from the outer frame bottom wall 501 .

[0034] In this embodiment, during the pouring process, when the molding base plate 3 slides down due to the pressure of cement, the first elastic member 11 is compressed. When the cement pressure decreases or disappears, the elastic restoring force of the first elastic member 11 will push the molding base plate 3 away from the bottom wall 501 of the outer frame, so that it returns to the initial position or close to the initial position. The provision of the first elastic member 11 can provide a certain buffering effect for the molding base plate 3, reducing the impact and damage to the mold structure caused by the instantaneous increase in cement pressure during the pouring process. Secondly, it helps to quickly reset the molding base plate 3 after the pouring is completed, facilitates the disassembly and next use of the mold, and improves work efficiency. Furthermore, it can balance the pressure on the molding base plate 3, making its sliding motion more stable, thereby ensuring the stability of the internal structure of the mold and the molding quality of the prefabricated components.

[0035] In some examples, the side wall of the second side plate 2 has a clamping portion 201 and also includes a second pushing piece 12. One end of the second pushing piece 12 is horizontally slidably arranged on the first pushing piece 4, and the other end is slidably abutted against the side wall of the second side plate 2. The second pushing piece 12 has a clamping portion 1201. After the second pushing piece 12 slides horizontally, the clamping portion 201 slidably abuts against the clamped portion 1201 to prevent the first pushing piece 4 and the second pushing piece 12 from sliding down.

[0036] In the present embodiment, the second push piece 12 slides on the first push piece 4 and the second side plate 2 at the same time. During operation, as the pouring process proceeds, when it is necessary to provide a larger area of ​​support to the second side plate 2 to balance the internal pressure, the second push piece 12 is pushed to slide on the first push piece 4 and the second side plate 2. Due to the misaligned sliding of the second push piece 12 and the first push piece 4, the contact area is increased, and a more uniform and wider supporting force can be applied to the second side plate 2. When the second push piece 12 slides to a position that can provide the maximum supporting force, the clamping portion 201 and the clamped portion 1201 abut against each other and clamp. This clamping action can ensure that during the pouring process, even if subjected to larger internal pressure fluctuations, the second push piece 12 can remain in the current pressurized position, and will not slip off or loosen due to unstable pressure, thereby always providing stable and reliable support for the second side plate 2.

[0037] In general, firstly, the slidable design of the second push piece 12 can flexibly adjust the support area and position according to the actual pressure demand, realize more accurate and effective support for the second side plate 2, and improve the adaptability and pressure balance ability of the mold. Secondly, the setting of the clamping part 201 and the clamped part 1201 ensures that the second push piece 12 is firmly locked at the maximum pressure position, effectively prevents slipping and loosening caused by pressure fluctuations, ensures the stability and reliability of the mold during the casting process, and thus improves the molding quality of the prefabricated component.

[0038] In some examples, the clamping portion 201 has a rising section 202 and a straight section 203 , and the clamped portion 1201 is configured such that, during the rising and horizontal sliding process, the clamped portion 1201 slides and abuts against the rising section 202 , and after sliding, the clamped portion 1201 is located on the straight section 203 .

[0039] In this embodiment, during operation, when the second pushing member 12 rises and slides horizontally, the clamped portion 1201 first slides and abuts against the rising section 202. As the second pushing member 12 continues to slide, the clamped portion 1201 gradually rises along the rising section 202 until it slides to a position in contact with the straight section 203. Subsequently, the clamped portion 1201 is clamped with the straight section 203 to achieve locking.

[0040] In general, firstly, the design of the rising section 202 enables the second push piece 12 to transition more smoothly during the rising and sliding process, reduces jamming and resistance, and improves the fluency of operation. Secondly, the clamping structure between the clamped portion 1201 and the straight section 203 is simple and stable, which can effectively prevent the second push piece 12 from accidentally loosening and sliding during operation, and ensure the stability and reliability of the mold during the casting process. Furthermore, this segmented clamping structure facilitates the accurate alignment and clamping of the second push piece 12, and improves the efficiency of mold assembly and adjustment.

[0041] In some examples, the side wall of the second side panel 2 also has a first stop portion 204, and also includes a second sliding block 13, which is set on the second side panel 2 for lifting and sliding. After the second sliding block 13 rises and slides, it abuts against the first stop portion 204; one end of the fourth connecting rod 14 is hinged to the second sliding block 13, and the other end is hinged to the second push member 12.

[0042] In this embodiment, during the pouring process, the second sliding block 13 rises, plays a guiding role and provides a lateral driving force for the other end of the fourth connecting rod 14. After receiving the driving force, the fourth connecting rod 14 drives the second push piece 12 to slide horizontally, so that the second push piece 12 supports and pressurizes the second side plate 2, and continuously maintains the locking force on the second push piece 12 to ensure its stable position and provide effective support. When the concrete component solidifies and needs to be demoulded, the second sliding block 13 is knocked by hand or equipment to make it slide down. During the sliding process, the second sliding block 13 cancels the locking force on the second push piece 12. At the same time, the vibration effect generated by the knocking is transmitted through the second push piece 12, the first push piece 4, the second side plate 2 and the molding bottom plate 3 in turn. This extensive vibration transmission allows the overall mold and the molded concrete component to loosen quickly, achieving the effect of rapid demoulding.

[0043] In general, firstly, during the pouring process, the cooperation between the second sliding block 13 and the fourth connecting rod 14 can realize the precise control and stable locking of the second push piece 12, ensure the structural stability and reliability of the mold during pouring, and thus improve the molding quality of the prefabricated component. Secondly, during the demoulding stage, rapid demoulding is achieved by knocking the second sliding block 13, which greatly improves production efficiency and reduces demoulding time and the difficulty of manual operation. Furthermore, the extensive transmission of vibration between the various parts of the mold can evenly loosen the mold and the concrete component, avoiding demoulding difficulties and component damage caused by local adhesion.

[0044] like Figure 5~Figure 6 As shown, in some examples, the second side panel 2 further has an air hole 205, which is located at the bottom of the side wall of the second side panel 2 and on the side of the second side panel 2 close to the first side panel 1. The air hole 205 is used to connect the molding space 101 with the outside world. It also includes a third sliding block 15, which is horizontally slidably arranged on the second side panel 2 in the transverse direction. The third sliding block 15 has a connecting port 1501. After the third sliding block 15 is configured to slide, the connecting port 1501 is connected to or disconnected from the air hole 205.

[0045] In this embodiment, at the beginning of pouring, the molding base plate 3 will slide down in a small range. During this sliding stroke, the third sliding block 15 slides horizontally to connect the connecting port 1501 with the air hole 205. At this time, the gas located at the three-sided angle formed by the first side plate, the second side plate and the molding base plate can be discharged. After the exhaust is completed, the third sliding block 15 is slid to cancel the connection between the connecting port 1501 and the air hole 205. Since no new gas cavity will be generated at this position during the subsequent cement pouring process, the quality of the prefabricated component at this critical position is guaranteed.

[0046] In general, this solution first sets air holes 205 at the three-sided angle that is difficult to cover with concrete, which can effectively discharge the gas accumulated here, avoid the formation of gas cavities in the prefabricated components, and significantly improve the quality and structural integrity of the prefabricated components. Secondly, by accurately controlling the sliding timing and position of the third sliding block 15, accurate management of the exhaust process is achieved, ensuring that the air holes 205 are connected only when exhaust is needed, reducing the uncertainty in the concrete pouring process. Furthermore, this exhaust method effectively solves the quality problems that are prone to occur in similar parts of traditional molds, and improves the casting success rate and product qualification rate of the mold.

[0047] In some examples, one end of the third sliding block 15 has a snap-in portion 1502, and the molding base plate 3 also has a first slot portion 301 and a second slot portion 302. The first slot portion 301 and the second slot portion 302 are vertically adjacent to each other. The molding base plate 3 is configured such that after lifting and sliding, the snap-in portion 1502 leaves the first slot portion 301 and enters the second slot portion 302, or leaves the second slot portion 302 and enters the first slot portion 301.

[0048] In this embodiment, the snap-in portion 1502 at one end of the third sliding block 15 cooperates with the first snap-in slot portion 301 and the second snap-in slot portion 302 of the molding base plate 3, respectively. When the molding base plate 3 is in the initial position, the snap-in portion 1502 snaps into the first snap-in slot portion 301, and at this time, the position of the third sliding block 15 makes the communication port 1501 and the air hole 205 in a dislocated and disconnected state. During the pouring process, as the concrete is injected, the molding base plate 3 slides down to the bottoming position, and at this time, the snap-in portion 1502 leaves the first snap-in slot portion 301 and snaps into the second snap-in slot portion 302, and similarly makes the communication port 1501 and the air hole 205 remain dislocated and disconnected.

[0049] In general, firstly, the first and second slots 301, 302 and the snap-in portion 1502 are engaged with each other at the initial position and the bottoming position of the molding base plate 3, ensuring that the air holes 205 are in a closed state at these two key positions, effectively guaranteeing the sealing performance of the molding space. Secondly, whether the molding base plate 3 is in an initial state without load or in a bottoming state under a large load, good sealing performance can prevent concrete leakage and ensure the dimensional accuracy and quality of the prefabricated components.

[0050] In some examples, the first slot portion 301 has a first guide slope 303 on one side close to the second slot portion 302, and the upper side of the third sliding block 15 has a second guide slope 1503. The molding base plate 3 is configured such that, after sliding downward, the first guide slope 303 slides against the second guide slope 1503 and drives the third sliding block 15 to slide horizontally, so that the air hole 205 is connected with the connecting port 1501.

[0051] In this embodiment, when the molding base plate 3 slides downward, the first guide slope 303 of the first slot portion 301 close to the second slot portion 302 slides and abuts against the second guide slope 1503 on the upper side of the third sliding block 15. As the molding base plate 3 continues to descend, the first guide slope 303 slides along the second guide slope 1503, generating a horizontal component force, thereby driving the third sliding block 15 to slide horizontally. When the third sliding block 15 slides horizontally to a certain position, the air hole 205 is connected to the communication port 1501 to achieve specific functional requirements, such as exhaust or other operations.

[0052] In this solution, through the cooperation of the first guide slope 303 and the second guide slope 1503, the vertical movement of the molding base plate 3 is transmitted to the horizontal movement of the third sliding block 15, which can automatically realize the connection between the air hole 205 and the connecting port 1501 at a specific stage of the descent of the molding base plate 3, thereby realizing the rapid discharge of the gas cavity at the three-side angle formed between the first side plate, the second side plate and the molding base plate in this process.

[0053] In some examples, a second elastic member 16 is further included, one end of the second elastic member 16 acts on the second side plate 2, and the other end acts on the third sliding block 15 to provide a force for the third sliding block 15 to slide toward the first slot portion 301 or the second slot portion 302.

[0054] In this embodiment, when the molding base plate 3 rises and resets under the action of the first elastic member 11 or slides down under the action of the gravity of the cement, the elastic force of the second elastic member 16 will pull the third sliding block 15 to slide toward the corresponding slot portion to achieve the offset closure of the air hole 205 and the connecting port 1501.

Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
