Description

Precast component casting molds for building construction Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular, to a casting mold for prefabricated components used in building engineering. Background Technology

[0002] During the construction process, a large number of precast components are required. These precast components in building projects are usually concrete components. To ensure the quality of concrete components, they are usually cast using specialized casting molds.

[0003] For example, Chinese utility model patent CN215969282U discloses a casting mold for construction engineering, including a workbench, a mold box at the upper end of the workbench, limit sliding rods fixedly connected to the four corners of the bottom surface of the mold box, limit sliding holes that cooperate with the limit sliding rods at the upper end of the workbench, a vibration motor fixedly connected to the upper end of the workbench, a vibration plate fixedly connected to the bottom surface of the mold box above the vibration motor, a vibration spring fixedly connected between the vibration plate and the vibration motor, a support frame spanning the mold box at the upper end of the workbench, a first hydraulic cylinder fixedly connected to the upper end of the support frame, a guide plate slidably connected to one end of the output of the first hydraulic cylinder extending to the inner side of the support frame, a pressure plate fixedly connected to the lower end of the guide plate, and a stripping template slidably connected to the bottom surface of the mold box. After the concrete is poured into the mold box, the vibration motor is started. The vibration motor drives the mold box to vibrate through the vibration spring and the vibration plate. During the vibration process, the air bubbles in the concrete are discharged. The first hydraulic cylinder is started to drive the guide plate to press down the pressure plate and seal the upper end of the mold box. This can effectively prevent air bubbles generated during the casting process and greatly improve the quality of the concrete bricks. The formwork and the inner wall of the mold box are covered with disposable plastic film.

[0004] However, the above-mentioned casting mold has the following problems: 1. Since there is no dedicated raw material feeding component, manual or other mechanical equipment is required for feeding. Moreover, the feeding process is easily obstructed and interfered with by the guide plate, resulting in a slow feeding speed for precast components used in construction projects, which in turn leads to low processing efficiency of precast components used in construction projects; 2. Since disposable plastic film is set on the inner wall of the mold box and the unloading template to avoid raw material residue, the disposable plastic film needs to be replaced frequently during the casting process of precast components used in construction projects. The replacement process is cumbersome and complicated, which wastes a lot of manpower and resources and greatly reduces the processing efficiency of precast components used in construction projects. Summary of the Invention

[0005] This invention provides a casting mold for precast components in building construction, which solves the technical problems of slow raw material feeding speed, cumbersome and troublesome measures to avoid raw material residue, and low processing efficiency of precast components in building construction.

[0006] According to one aspect of the present invention, a casting mold for precast components in building construction is provided, comprising an installation frame, a casting shell, a discharge pusher plate, a die-casting assembly, a discharge assembly, and a feeding assembly. The casting shell is disposed on the installation frame. The discharge pusher plate is vertically and movably disposed within the casting shell. The die-casting assembly is disposed on the installation frame with its extrusion end positioned above the casting shell. The extrusion end of the die-casting assembly is used to move vertically downward to extrude and form the precast component in building construction, and after the precast component is formed, it moves vertically upward to reset. The discharge assembly is disposed on the installation frame. The push-pull end of the feeding assembly is located below the casting shell. The push-pull end of the feeding assembly is connected to the feeding push plate and is used to push the feeding push plate upward in a vertical direction to push the prefabricated building components out of the casting shell. After pushing out the prefabricated building components, the feeding push plate is pulled downward in a vertical direction to reset. The output end of the feeding assembly is connected to the upper opening of the casting shell and is used to receive raw materials and transport the raw materials into the casting shell. The bottom of the casting shell is provided with a guide structure for the feeding push plate to move upward a preset distance to form a guide channel to guide the remaining raw materials out of the casting shell.

[0007] As a further improvement to the above technical solution:

[0008] Furthermore, the feeding assembly includes a storage shell for receiving and accommodating raw materials, a stirring component rotatably disposed within the storage shell, a feeding pipe connected to the upper opening of the casting shell and the output end of the storage shell respectively, a conveying component rotatably disposed within the feeding pipe, and a drive component whose output end is connected to the stirring component and the conveying component respectively, for driving the stirring component to rotate to stir the raw materials and driving the conveying component to rotate to convey the raw materials.

[0009] Furthermore, the driving component includes a driving motor, a first stirring gear fixedly sleeved on the output shaft of the driving motor and meshing with the stirring component gear, and a first conveying gear fixedly sleeved on the output shaft of the driving motor and meshing with the conveying component gear.

[0010] Furthermore, the stirring component includes a stirring shaft rotatably arranged inside the storage shell, a stirring rod fixedly sleeved on the stirring shaft, and a first spiral blade spirally arranged along the axial direction of the stirring rod for spirally conveying raw materials to the output end of the storage shell as the stirring shaft rotates. The connecting end of the stirring shaft extends out of the storage shell and is fixedly sleeved with a second stirring gear that meshes with the first stirring gear.

[0011] Furthermore, the conveying component includes a conveying shaft rotatably arranged inside the feeding pipe and a second spiral blade spirally arranged along the axial direction of the conveying shaft for spirally conveying raw materials to the casting shell as the conveying shaft rotates. The connecting end of the conveying shaft extends out of the feeding pipe and is fixedly fitted with a second conveying gear that meshes with the first conveying gear.

[0012] Furthermore, the flow guiding structure includes a limiting part that extends radially inward from the bottom inner wall of the casting shell and abuts against the outer peripheral wall of the feeding pusher plate, a flow guiding hole opened at the bottom of the casting shell, and a flow guiding plate arranged on the bottom outer wall of the casting shell.

[0013] Furthermore, the outer peripheral wall of the lower end of the feeding pusher is inclined with a guide groove that extends inward in the radial direction and downward in the vertical direction. Multiple guide grooves are arranged at intervals along the circumference of the feeding pusher. The guide grooves are connected to the guide holes, and the guide grooves and guide holes are arranged in a one-to-one correspondence.

[0014] Furthermore, the die-casting assembly includes a die-casting hydraulic rod arranged vertically on the mounting frame and above the casting shell, a die-casting guide rod arranged vertically and movable on the mounting frame, a die-casting return spring sleeved on the die-casting guide rod and connected to the first end of the die-casting guide rod and the mounting frame respectively, and a die-casting plate connected to the extrusion end of the die-casting hydraulic rod and the second end of the die-casting guide rod respectively.

[0015] Furthermore, a connecting threaded sleeve is provided on the upper surface of the die-cast plate, and the connecting threaded sleeve is threadedly connected to the die-cast guide rod.

[0016] Furthermore, the unloading assembly includes an unloading hydraulic rod arranged vertically on the mounting frame and located below the casting shell, a connecting push plate connected to the push-pull end of the unloading hydraulic rod, an unloading push rod whose first end is connected to the connecting push plate and whose second end passes through the bottom of the casting shell to connect with the unloading push plate, an unloading guide rod whose first end is connected to the bottom of the casting shell and whose second end passes through the connecting push plate, and an unloading reset spring sleeved on the unloading guide rod and connected to the bottom of the casting shell and the connecting push plate respectively. Both the unloading guide rod and the unloading push rod are arranged vertically.

[0017] The present invention has the following beneficial effects:

[0018] The precast component casting mold for building construction of this invention uses a frame to reasonably and reliably install a casting shell, a feeding pusher plate, and a die-casting assembly. The die-casting assembly is positioned above the casting shell, facilitating the downward movement of its extrusion end to extrude and form the precast component. The feeding assembly is positioned below the die-casting assembly, facilitating the upward movement of its push-pull end to eject the precast component. During the casting process, the feeding assembly first receives and transports the raw material into the casting shell to ensure efficient feeding. Then, the extrusion end of the die-casting assembly moves vertically downward to extrude and form the precast component. After forming, the die-casting assembly moves vertically upward to reset, providing space for feeding. Finally, the push-pull end of the feeding assembly pushes the feeding pusher plate upward to eject the precast component from the casting shell. After the precast components for building construction are unloaded, the push-pull end of the unloading assembly pulls the unloading push plate downwards vertically to reset it, providing space for the raw material to be fed. Finally, the push-pull end of the unloading assembly pushes the unloading push plate upwards a preset distance, forming a flow channel through the guide structure to guide the remaining raw material out of the casting shell, preventing the residual raw material from solidifying inside the casting shell and affecting the quality of the precast components. This process is repeated to achieve continuous casting of precast components for building construction. This solution uses the coordinated operation of the installation frame, casting shell, unloading push plate, die-casting assembly, unloading assembly, and loading assembly. The raw material is fed through a dedicated loading assembly, while the flow channel removes residual raw material. Compared with existing technologies, this greatly improves the feeding speed of raw materials, and the measures to avoid raw material residue are simple and convenient. The processing efficiency of precast components for building construction is high, the quality is reliable, and the practicality is strong, making it suitable for widespread promotion and application.

Detailed Implementation

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] Figure 1 is a structural schematic diagram of a precast component casting mold for building engineering according to a preferred embodiment of the present invention; Figure 2 is an enlarged structural schematic diagram of part A of the precast component casting mold for building engineering shown in Figure 1; Figure 2 is an enlarged structural schematic diagram of part B of the precast component casting mold for building engineering shown in Figure 1.

[0028] As shown in Figure 1, the precast component casting mold for building construction in this embodiment includes an installation frame 100, a casting shell 200, a feeding pusher plate 300, a die-casting assembly 400, a feeding assembly 500, and a feeding assembly 600. The casting shell 200 is arranged on the installation frame 100. The feeding pusher plate 300 is vertically and movably arranged inside the casting shell 200. The die-casting assembly 400 is arranged on the installation frame 100 with its extrusion end above the casting shell 200. The extrusion end of the die-casting assembly 400 is used to move vertically downward to extrude and form the precast component for building construction, and after the precast component is formed, it moves vertically upward to reset. The feeding assembly 500 is arranged on the installation frame. The push-pull end of the feeding assembly 500 is located below the casting shell 200. The push-pull end of the feeding assembly 500 is connected to the feeding push plate 300 and is used to push the feeding push plate 300 upward in a vertical direction to push the precast component for building construction out of the casting shell 200. After pushing out the precast component for building construction, the feeding push plate 300 is pulled downward in a vertical direction to reset. The output end of the feeding assembly 600 is connected to the upper opening of the casting shell 200 and is used to receive raw materials and transport the raw materials into the casting shell 200. The bottom of the casting shell 200 is provided with a guide structure 700 for the feeding push plate 300 to move upward a preset distance to form a guide channel to guide the remaining raw materials out of the casting shell 200.Specifically, the precast component casting mold for building construction of the present invention uses a mounting frame 100 to reasonably and reliably install a casting shell 200, a feeding pusher plate 300, and a die-casting assembly 400. This positions the die-casting assembly 400 above the casting shell 200, facilitating downward movement of the extrusion end of the die-casting assembly 400 to extrude and form the precast component for building construction. The feeding assembly 500 is positioned below the die-casting assembly 400, facilitating upward movement of the push-pull end of the feeding assembly 500 to eject the precast component for building construction. This allows the precast component to be cast into a mold. During the molding process, the raw materials are first received by the feeding assembly 600 and transported into the casting shell 200 to ensure feeding efficiency. Then, the extrusion end of the die-casting assembly 400 moves vertically downward to extrude and form the precast components for building construction. After the precast components are formed, they move vertically upward to reset, providing space for unloading. Finally, the push-pull end of the unloading assembly 500 pushes the unloading push plate 300 upward to push the precast components out of the casting shell 200. After the precast components for building construction are unloaded, the push-pull end of the unloading assembly 500 pulls the unloading push plate 300 downwards vertically to reset it, providing space for the material to be loaded. Finally, the push-pull end of the unloading assembly 500 pushes the unloading push plate 300 upwards a preset distance, so that the remaining material is guided out of the casting shell 200 through the guide structure 700 to form a guide channel, preventing the remaining material from solidifying inside the casting shell 200 and affecting the quality of the precast components for building construction. This process is repeated to achieve the goal of building construction... This solution utilizes precast components for continuous casting. The installation frame 100, casting shell 200, material feeding pusher 300, die-casting assembly 400, material feeding assembly 500, and feeding assembly 600 work together in a coordinated manner. The dedicated feeding assembly 600 feeds the raw materials, while the guide structure 700 removes residual materials. Compared to existing technologies, this significantly improves the material feeding speed, and the measures to avoid material residue are simple and convenient. The precast components used in construction engineering have high processing efficiency and reliable quality, are highly practical, and suitable for widespread promotion and application. It should be understood that the preset distance can be adaptively set according to the specific dimensions of the guide structure 700 to ensure the formation of a guide channel.

[0029] As shown in Figures 1 and 2, in this embodiment, the feeding assembly 600 includes a storage shell 610 for receiving and accommodating raw materials, a stirring element 620 rotatably disposed within the storage shell 610, a feeding pipe 630 connected to the upper opening of the casting shell 200 and the output end of the storage shell 610 respectively, a conveying element 640 rotatably disposed within the feeding pipe 630, and a drive element 650 whose output end is connected to both the stirring element 620 and the conveying element 640, for driving the stirring element 620 to rotate to stir the raw materials and simultaneously driving the conveying element 640 to rotate to convey the raw materials. Specifically, after the raw materials are poured into the storage shell 610, the drive element 650 operates to drive the stirring element 620 to rotate and stir the raw materials, so that the components of the raw materials are mixed evenly. At the same time, it drives the conveying element 640 to rotate, so as to evenly convey the evenly mixed raw materials into the casting shell 200, thereby improving the feeding efficiency and the quality of the precast components for building construction after casting.

[0030] As shown in Figures 1 and 2, in this embodiment, the driving component 650 includes a driving motor 651, a first stirring gear 652 fixedly sleeved on the output shaft of the driving motor 651 and meshing with the stirring component 620, and a first conveying gear 653 fixedly sleeved on the output shaft of the driving motor 651 and meshing with the conveying component 640. Specifically, the driving motor 651 operates to simultaneously drive the first stirring gear 652 and the first conveying gear 653 to rotate, thereby simultaneously driving the stirring component 620 meshing with the first stirring gear 652 and the conveying component 640 meshing with the first conveying gear 653 to rotate, realizing the stirring and conveying of raw materials. Optionally, the first stirring gear 652 is fixedly sleeved on the output shaft of the driving motor 651 through a square tube sleeve; and / or the first conveying gear 653 is fixedly sleeved on the output shaft of the driving motor 651 through a square tube sleeve.

[0031] As shown in Figures 1 and 2, in this embodiment, the stirring component 620 includes a stirring shaft 621 rotatably arranged within the storage shell 610, a stirring rod 622 fixedly sleeved on the stirring shaft 621, and a first spiral blade 623 spirally arranged along the axial direction of the stirring rod 622 for spirally conveying raw materials to the output end of the storage shell 610 as the stirring shaft 621 rotates. The connecting end of the stirring shaft 621 extends outside the storage shell 610 and is fixedly sleeved with a second stirring gear 624 that meshes with the first stirring gear 652. Specifically, when the first stirring gear 652 rotates, the second stirring gear 624 rotates synchronously to drive the stirring shaft 621 to rotate synchronously, thereby driving the stirring rod 622 to stir the raw materials. At the same time, the first spiral blade 623 spirally conveys the stirred raw materials to the conveying end of the storage shell 610. It should be understood that when the stirring shaft 621 is arranged vertically, the stirring rod 622 is above the first spiral blade 623. Optionally, multiple stirring rods 622 are arranged at intervals along the axial direction of the stirring shaft 621 to improve stirring efficiency.

[0032] As shown in Figures 1 and 2, in this embodiment, the conveying component 640 includes a conveying shaft 641 rotatably arranged within the feeding pipe 630 and second spiral blades 642 spirally arranged along the axial direction of the conveying shaft 641 for spirally conveying raw materials to the casting shell 200 as the conveying shaft 641 rotates. The connecting end of the conveying shaft 641 extends outside the feeding pipe 630 and is fixedly fitted with a second conveying gear 643 that meshes with the first conveying gear 653. Specifically, when the first conveying gear 653 rotates, the second conveying gear 643 rotates synchronously to drive the conveying shaft 641 to rotate synchronously, thereby spirally conveying the raw materials into the casting shell 200 through the second spiral blades 642. It should be understood that the gear meshing structure is simple and convenient for changing the direction of force transmission, thus facilitating the installation of the stirring component 620 and the conveying component 640 and avoiding mutual obstruction and interference. Optionally, the conveying shaft 641 is inclined, and the second spiral blades spirally and inclined upward to convey the raw materials so that they are not obstructed or interfered with by the die-casting assembly 400 during the feeding process.

[0033] As shown in Figure 3, in this embodiment, the flow guiding structure 700 includes a limiting part 710 extending radially inward from the bottom inner wall of the casting shell 200 and abutting against the outer peripheral wall of the discharge push plate 300, a flow guiding hole 720 formed at the bottom of the casting shell 200, and a flow guiding plate 730 disposed on the bottom outer wall of the casting shell 200. Specifically, after the discharge push plate 300 moves vertically upward a predetermined distance through the limiting part 710, a flow guiding gap is formed between the discharge push plate 300 and the inner wall of the casting shell 200. Residual raw materials flow out of the casting shell 200 through the flow guiding gap and the flow guiding hole 720, and are easily collected under the guidance of the flow guiding plate 730. It should be understood that the flow guiding channel includes the flow guiding gap and the flow guiding hole 720.

[0034] As shown in Figure 3, in this embodiment, a guide groove 740 extending radially inward and vertically downward is inclinedly formed on the outer peripheral wall of the lower end of the feeding push plate 300. Multiple guide grooves 740 are arranged at intervals along the circumference of the feeding push plate 300. The guide grooves 740 communicate with the guide holes 720, and the guide grooves 740 and guide holes 720 are arranged in a one-to-one correspondence. Specifically, the guide grooves 740 increase the communication area between the guide gap and the guide holes 720, thereby improving the guide efficiency; simultaneously, the preset distance can be shortened to guide residual raw materials in advance, further improving the guide efficiency.

[0035] As shown in Figure 1, in this embodiment, the die-casting assembly 400 includes a die-casting hydraulic rod 410 vertically arranged on the mounting frame 100 and above the casting housing 200, a die-casting guide rod 420 vertically movable on the mounting frame 100, a die-casting return spring 430 sleeved on the die-casting guide rod 420 and connected to the first end of the die-casting guide rod 420 and the mounting frame 100 respectively, and a die-casting plate 440 connected to the extrusion end of the die-casting hydraulic rod 410 and the second end of the die-casting guide rod 420 respectively. Specifically, the die-casting hydraulic rod 410 operates to drive the die-casting plate 440 to move vertically, enabling the die-casting of precast components for building construction and the repositioning of the die-casting plate 440. The die-casting guide rod 420 guides the movement of the die-casting plate 440, improving die-casting quality. When the die-casting plate 440 moves vertically downwards, it compresses the die-casting return spring 430 at the first end of the die-casting guide rod 420 to generate additional elastic force. When the die-casting hydraulic rod 410 no longer applies hydraulic pressure, the die-casting return spring 430, through the additional elastic force, drives the die-casting plate 440 to quickly return to its initial position until it reaches its initial state. At this point, the die-casting return spring 430 no longer generates additional elastic force. Thus, the initial position of the die-casting plate 440 can be adjusted and controlled through the die-casting return spring 430. Optionally, multiple die-casting guide rods 420 are arranged at intervals along the horizontal direction of the mounting frame 100, with the die-casting return spring 430 and the die-casting guide rod 420 arranged in a one-to-one correspondence.

[0036] As shown in Figure 1, in this embodiment, a connecting threaded sleeve 450 is provided on the upper surface of the die-cast plate 440, and the connecting threaded sleeve 450 and the die-casting guide rod 420 are threadedly connected. Specifically, by rotating the connecting threaded sleeve 450 and the die-casting guide rod 420 helically, the initial vertical position of the die-cast plate 440 is adjusted, thereby adjusting the distance of the die-cast plate 440 moving vertically downward, thereby controlling the thickness of the prefabricated component for building construction.

[0037] As shown in Figure 1, in this embodiment, the unloading assembly 500 includes an unloading hydraulic rod 510 arranged vertically on the mounting frame 100 and located below the casting housing 200, a connecting push plate 520 connected to the push-pull end of the unloading hydraulic rod 510, an unloading push rod 530 whose first end is connected to the connecting push plate 520 and whose second end passes through the bottom of the casting housing 200 to connect with the unloading push plate 300, an unloading guide rod 540 whose first end is connected to the bottom of the casting housing 200 and whose second end passes through the connecting push plate 520, and an unloading reset spring 550 sleeved on the unloading guide rod 540 and connected to the bottom of the casting housing 200 and the connecting push plate 520 respectively. The unloading guide rod 540 and the unloading push rod 530 are both arranged vertically. Specifically, the unloading hydraulic rod 510 operates to push and pull the connecting push plate 520 vertically, which in turn pushes and pulls the unloading push rod 530 vertically, thereby pushing and pulling the unloading push plate 300 vertically to eject the precast components for construction or pull the unloading push plate 300 back to its original position. During the pushing and pulling process, the unloading guide rod 540 guides the connecting push plate 520, indirectly guiding the unloading push rod 530 and the unloading push plate 300. When the connecting push plate 520 moves vertically upward, it compresses the unloading return spring 550, causing the unloading return spring 550 to generate additional elastic force. When the unloading hydraulic rod 510 no longer applies hydraulic pressure, the unloading return spring 550, through its additional elastic force, drives the connecting push plate 520 to quickly return to its original position. Optionally, multiple unloading guide rods 540 are arranged at intervals along the horizontal direction of the casting shell 200, with each unloading guide rod 540 and unloading return spring 550 corresponding to the other.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
