Description

Technical Field

[0001] The utility model relates to the technical field of precast concrete, in particular to an automatic core-pulling mechanism for a group of vertical molds. Background Art

[0002] Precast concrete components for residential use are divided into many types such as building exterior wall panels, building interior wall panels, building floor slabs, building staircases, coupling beams, balcony slabs, air-conditioning panels, etc. In the production process, flat molds are mostly used, that is, templates are arranged in a plane, and concrete is poured along the horizontal plane to form precast concrete components of various structures. The disadvantage of this flat mold production method is that the production efficiency is relatively low, the number of templates to be prepared is large, and the space occupied by the production line is large. To improve this situation, a method of group vertical molds is proposed in the prior art for the production of such precast components.

[0003] The existing core-pulling of group vertical molds mostly uses manual core-pulling. Manual core-pulling requires workers to grab the core pipes one by one through a crane for core-pulling. The efficiency of manual core-pulling is slow. Manual core-pulling cannot perform synchronous core-pulling on multiple core pipes, and has high requirements for the verticality of core-pulling. If the verticality cannot be achieved, it will cause the component to collapse, thus affecting the quality of the component. Summary of the Utility Model

[0004] The purpose of the present invention is to provide an automatic core-pulling mechanism for a group of vertical molds to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an automatic core-pulling mechanism for a group of vertical molds, including a base, an installation frame is arranged on the top of the base, a plurality of first sliders are slidably installed inside the installation frame, a core pipe mold is rotatably installed on the top of the plurality of first sliders, hydraulic cylinders are fixedly installed on both sides of the top of the base, and the output ends of the two hydraulic cylinders are respectively fixedly connected to the bottoms of both ends of the installation frame.

[0006] As a further description of the above technical scheme: a driving rod is slidably arranged inside the core pipe mold, the bottom end of the driving rod penetrates through the bottom of the first slider, a clamping block is fixedly installed on the side wall of the top end of the driving rod, clamping grooves are respectively arranged at the top and bottom inside the core pipe mold, the clamping block is adapted to the clamping groove, a movable groove is arranged inside the core pipe mold, the movable groove is arranged between the two clamping grooves, and the bottom end of the core pipe mold is in threaded cooperation with the middle part of the driving rod.

[0008] As a further description of the above technical solution: Extrusion blocks are slidably installed on both inner sides of the installation frame. The two extrusion blocks are in contact with the side walls of multiple first sliders. Connecting rods are fixedly installed at both ends of the two extrusion blocks. Support plates are fixedly installed on both sides of the top of the base. Trajectory grooves are formed on both sides of the two support plates.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Refer to Figures 1-5 , an automatic core-pulling mechanism for a grouped vertical mold, including a base 1. An installation frame 2 is provided on the top of the base 1. A plurality of first sliders 3 are slidably installed inside the installation frame 2. A core pipe mold 4 is rotatably installed on the tops of the plurality of first sliders 3. Hydraulic cylinders 5 are fixedly installed on both sides of the top of the base 1. The output ends of the two hydraulic cylinders 5 are respectively fixedly connected to the bottoms of both ends of the installation frame 2; during the prefabrication of concrete components, it is necessary to insert a plurality of core pipe molds 4 determined in position into the bottom of the mold for making concrete components. In order to ensure the overall verticality during core-pulling and thus avoid the collapse of the components, the present device raises the output end of the hydraulic cylinder 5 to drive the installation frame 2 to move downward, and drives the plurality of first sliders 3 and the core pipe mold 4 provided on the top of the first slider 3 to move downward as a whole through the installation frame 2, so as to achieve the purpose of synchronous core-pulling of the present device. Through the present device, it can be ensured that during the core-pulling process, the overall verticality is good, and it is ensured that the concrete components will not collapse during the core-pulling process.

[0023] As a preferred technical solution of this embodiment, a driving rod 6 is slidably arranged inside the core pipe mold 4. The bottom end of the driving rod 6 penetrates through the bottom of the first slider 3. A clamping block 7 is fixedly installed on the side wall of the top end of the driving rod 6. The top and bottom inside the core pipe mold 4 are both provided with clamping grooves 8. The clamping block 7 is adapted to the clamping grooves 8. An activity groove 9 is formed inside the core pipe mold 4. The activity groove 9 is arranged between the two clamping grooves 8. The bottom end of the core pipe mold 4 and the middle part of the driving rod 6 are in threaded fit. During the use of the core pipe mold 4, in order to make the demolding more smooth, a demolding agent needs to be applied on the surface of the core pipe mold 4. During the process of the core pipe mold 4 descending under the action of the hydraulic cylinder 5, the clamping block 7 is engaged with the clamping groove 8 at the bottom of the core pipe mold 4. At this time, the core pipe mold 4 cannot rotate under the action of the clamping block 7. When the core pipe mold 4 is successfully demolded, one side of the core pipe mold 4 faces outward. At this time, the demolding agent can be applied. Then the hydraulic cylinder 5 drives the core pipe mold 4 to press down again. The clamping block 7 enters the activity groove 9 inside the core pipe mold 4, and the core pipe mold 4 is disengaged from the clamping block 7. At this time, the bottom end of the core pipe mold 4 is in threaded fit with the driving rod 6. When the core pipe mold 4 continues to descend, due to the threaded transmission, the core pipe mold 4 will rotate, making the other side of the core pipe mold 4 rotate out, and the demolding agent is applied on it. The rotation of the core pipe mold 4 is realized through the driving rod 6.

[0024] As a preferred technical solution of this embodiment, a second slider 11 is fixedly installed at the bottom end of the driving rod 6. An activity seat 10 is fixedly installed on the top of the base 1. A plurality of the second sliders 11 are slidably installed on the top of the activity seat 10. By connecting the activity seat 10 and the second slider 11 to the driving rod 6, the driving rod 6 can cooperate with and follow the movement of the first slider 3 and the core pipe mold 4.

[0025] As a preferred technical solution of this embodiment, extrusion blocks 13 are slidably installed on both sides inside the installation frame 2. The two extrusion blocks 13 are in contact with the side walls of a plurality of the first sliders 3. Link rods 14 are fixedly installed at both ends of the two extrusion blocks 13. Support plates 12 are fixedly installed on both sides of the top of the base 1. Trajectory grooves 15 are formed on both sides of the two support plates 12. The link rods 14 are slidably installed inside the trajectory grooves 15. During the use of this device, in order to meet the core-pulling distances of different components, the core pipe mold 4 is driven to move by sliding the first slider 3 to adjust the distance between the core pipe molds 4. After the distance adjustment is completed, in order to ensure the stability of the core pipe mold 4, the side walls of a plurality of the first sliders 3 are extruded by the two extrusion blocks 13 to fix the first sliders 3. In actual use, the tops of the two trajectory grooves 15 on the same support plate 12 are close to each other, and the bottoms are far from each other. When the hydraulic cylinder 5 drives the installation frame 2 to rise and fall, when the installation frame 2 reaches the top, the two extrusion blocks 13 approach each other to extrude and fix the first slider 3. When the installation frame 2 reaches the bottom, the two extrusion blocks 13 move away from each other under the drive of the link rods 14, releasing the first slider 3, so that the first slider 3 can move on the installation frame 2.

[0026] As a preferred technical solution of this embodiment, a plurality of springs 16 are fixedly installed on the side walls of the two extrusion blocks 13 away from the first sliders 3. One ends of the plurality of springs 16 away from the extrusion blocks 13 are fixedly connected to the inside of the installation frame 2. When the extrusion blocks 13 extrude and fix the first sliders 3, the middle parts of the extrusion blocks 13 are supported.

[0027] As a preferred technical solution of this embodiment, a sliding rod 17 is fixedly installed inside the installation frame 2. The sliding rod 17 is slidably matched with a plurality of the first sliders 3. The sliding rod 17 is used to assist a plurality of the first sliders 3 to move on the installation frame 2.
