Description

Technical Field

[0001] This utility model relates to the field of molds, specifically a mold for a concrete pipe socket. Background Technology

[0002] When concrete pipe sockets are formed using a special mold, the combined socket mold consists of a basic bottom mold and a ring-shaped assembly jig. The jig is fixed to the bottom mold by screws. During use, the ring-shaped jig must be assembled onto the bottom mold and positioned by screws to ensure that the sealing strip is embedded in the sealing groove to prevent concrete leakage. The mold can be replaced by loosening the screws during disassembly. When pouring concrete into the combined mold, it is impossible to pour evenly inside the mold, resulting in uneven distribution of concrete inside the mold. Even if vibration equipment is used for vibration afterward, blind spots will be formed due to the internal contour of the mold. At the right-angle connection between the jig and the bottom mold, the vibrator cannot effectively reach, causing air and moisture to be trapped and forming voids. In addition, if the sealing strip is not installed tightly, leakage will take away the mortar, causing honeycomb pitting on the concrete surface and reducing its impermeability.

Detailed Implementation

[0015] Please see Figure 1-5This utility model provides a concrete pipe socket mold, including a sub-mold A100, a sub-mold B200 installed on one side of the sub-mold A100, a sub-mold C300 installed on one side of the sub-mold B200, and a sub-mold D400 installed on one side of the sub-mold C300; an outer mold frame 11 is installed on the outer side of the sub-mold A100, and an inner mold frame 14 is fixedly installed on the inner side of the outer mold frame 11, and a mold cavity 17 is formed between the inner mold frame 14 and the outer mold frame 11; a flow guide seat 16 is fixedly installed on the top of the inner mold frame 14.

[0016] Working Principle: In actual use, molds A100, B200, C300, and D400 are screwed together using mating plates 18. The outer sides of all four mold groups are reinforced with multiple sets of longitudinal reinforcing ribs 111 and transverse reinforcing ribs 112. Simultaneously, multiple support frames 15 support the inner mold frames 14 within the four mold groups. Concrete is then poured onto four sets of conical guide seats 16 using concrete pouring equipment, ensuring even pouring of concrete into the mold cavity 17. Combined with the use of vibrating equipment, the screwed connections of molds A100, B200, C300, and D400 with the mating plates 18 ensure the tightness of the four mold group connections. With improved stability, it effectively reduces grout leakage during pouring and facilitates later disassembly. Multiple sets of longitudinal reinforcing ribs 111 and transverse reinforcing ribs 112 on the outside form a three-dimensional reinforcement structure, which can significantly improve the overall rigidity of the mold, resist the lateral pressure generated during concrete pouring and vibration, avoid mold deformation, and ensure the accurate shape and dimensions of the socket. Multiple sets of internal support frames 15 support the inner mold frame 14 inside the four sets of molds, which can stabilize the shape of the inner mold and ensure the consistency of the inner structural dimensions of the socket. The four sets of conical flow guide seats 16 can guide the concrete to flow evenly into the mold cavity 17, avoiding local accumulation or uneven distribution. When used with vibration equipment, it can further promote concrete compaction, reduce defects such as air bubbles and honeycomb surface, and ultimately improve the forming quality and structural strength of the concrete pipe socket.

[0017] In a preferred embodiment, the sub-molds A100, B200, C300 and D400 have the same structure, and are fixed together by screws through the mating plate 18.

[0018] The molds A100, B200, C300 and D400 are combined to form the main body of the socket mold, and the top and bottom of the socket mold are both conical.

[0019] The mold A100 also includes a pouring hopper 12, a socket mold base 13, a support frame 15, and a docking plate 18; the pouring hopper 12 is fixedly connected to the top of the outer mold frame 11, and a concrete guiding space is formed between the pouring hopper 12 and the guide seat 16, and the concrete guiding space is annular.

[0020] The socket mold base 13 is fixedly connected to the bottom of the outer mold frame 11, and the cross section of the outer mold frame 11 is U-shaped.

[0021] like Figure 1-4 As shown: Sub-molds A100, B200, C300 and D400 are bolted together by the butt plate 18 to form a sturdy overall frame; at the same time, multiple sets of longitudinal reinforcing ribs 111 and transverse reinforcing ribs 112 are set on their outer sides, which greatly enhances the mold's ability to resist the lateral pressure of concrete and effectively prevents the mold from deforming or bulging during the pouring process. Multiple sets of support frames 15 support the inner mold frame 14 to ensure that the inner mold frame 14 remains stable under the impact and pressure of concrete; this ensures that the size and shape of the mold cavity 17 are accurate, so that the concrete component cast has accurate cross-sectional dimensions and regular shape. Efficient and uniform concrete diversion: The design of four sets of conical diversion seats 16 can effectively divert and guide the poured concrete, so that the concrete can be filled into various parts of the mold cavity 17 more evenly and stably, avoiding segregation or uneven aggregate distribution caused by direct impact of concrete on a certain area of ​​the mold cavity 17, and also reducing pouring dead corners. It facilitates compaction and improves component quality. The uniform concrete distribution creates favorable conditions for subsequent vibration. When used with a vibrating device, air bubbles inside the concrete are more easily expelled, and aggregates and mortar can be fully and densely filled into every corner of the mold cavity 17. It helps to significantly reduce the risk of defects such as honeycomb, pitting, and holes in the components. The internal density and surface smoothness of the final formed components are improved, and the impermeability of the pipe socket is enhanced.

[0022] The modular design is achieved by using four separate molds connected by 18 screws on a mating plate. This makes the transportation, assembly, and disassembly of the molds more flexible and convenient. When different specifications need to be produced or parts need to be repaired or replaced, specific molds can be operated, improving efficiency and economy.

[0023] In a preferred embodiment, multiple sets of support frames 15 are fixedly provided on the inner side of the inner mold frame 14, and the support frames 15 are fan-shaped. At the same time, the multiple sets of support frames 15 form a support structure for the inner mold frame 14.

[0024] A flow guide seat 16 is fixedly provided on the top of the inner mold frame 14, and four sets of flow guide seats 16 are combined together to form a conical backflow cone. Meanwhile, a mold cavity 17 is provided at the bottom of the backflow cone.

[0025] Longitudinal reinforcing ribs 111 and transverse reinforcing ribs 112 are fixedly provided on the outer circumferential outer wall of the outer mold frame 11, and the angle between the longitudinal reinforcing ribs 111 and the transverse reinforcing ribs 112 is 90 degrees.

[0026] During the forming process of the concrete pipe socket: the sub-molds A100, B200, C300 and D400 are bolted together and fixed by the butt plate 18 to form a complete cylindrical outer mold, and reinforced with longitudinal reinforcing ribs 111 and transverse reinforcing ribs 112; then, the concrete is evenly poured into the mold cavity 17 through the guide seat 16, and the vibrating equipment is started to fully vibrate to remove air bubbles and ensure compaction; after the concrete has solidified and reached its strength, the bolts on the butt plate 18 and each sub-mold are removed in sequence to obtain a concrete pipe socket with accurate dimensions and regular interface shape.
