Description

Technical Field

[0001] The utility model relates to the technical field of concrete pile mould forming, in particular to a magnetic locking device for a wood-grain imitation concrete pile casting mould. Background Art

[0002] In order to improve the molding efficiency of the imitation wood grain concrete piles in the prior art, a matching mold is provided for casting, and in order to improve the quality of the imitation wood grain concrete piles, an inner skeleton is cast inside the imitation wood grain concrete piles.

[0003] In the actual pouring process, in order to achieve convenient matching and plugging between multiple imitation wood grain concrete piles, matching plug-in columns and lower open grooves are provided on both ends of the inner frame, wherein the plug-in columns are located on the outside of the imitation wood grain concrete piles, and the lower open grooves are cast in the imitation wood grain concrete piles, and the openings are exposed. Therefore, during the pouring process, the matching accuracy after molding needs to be ensured, and concrete mud cannot be poured into the lower open groove.

[0004] In order to ensure the sealing of the lower opening groove during pouring, it is necessary to make the inner wall of the lower end of the lower opening groove fit closely to the bottom mold to avoid the infiltration of concrete slurry. In the prior art, rigid connection is usually used to achieve the purpose of pressing the inner skeleton downward. When it comes to rigid connection structures such as pins, bolts or latches, due to the solidification and expansion of concrete slurry or other environmental factors during pouring, gaps or looseness will appear on the connection surface of the rigid connection position, and the rigid connection will cause wear after long-term use, resulting in reduced extrusion strength of the lower opening groove, which cannot meet the sealing requirements; at the same time, the rigid connection needs to be manually locked before pouring and manually unlocked during demoulding, which requires high professional operating skills of workers and has potential instability risks for the final presentation of the construction effect. The magnetic locking device can be easily locked and unlocked without the need for full-time personnel to operate, which greatly improves production efficiency while meeting the functional requirements.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 6 , the utility model provides a technical solution:

[0029] A magnetic locking device for a wood-grain imitation concrete pile casting mold, the magnetic locking device is installed on the wood-grain imitation concrete pile casting mold, the wood-grain imitation concrete pile casting mold includes a bottom mold 1 and multiple sets of side molds 2 distributed symmetrically, the multiple sets of side molds 2 are movably installed on the bottom mold 1, and the side molds 2 are slidably installed by rollers 12 or rotatably installed by hinge devices 11.

[0030] An inner frame 5 is provided in the casting cavity formed by closing the bottom mold 1 and the side mold 2, and a lower opening groove 6 is provided at the lower end of the inner frame 5, which is in contact with the upper end surface of the bottom mold 1. The magnetic locking device includes a positioning rod 4 and a magnetic block 3. The magnetic block 3 is installed on the bottom mold 1, and the positioning rod 4 is inserted into the lower opening groove 6. The outer contour of the positioning rod 4 is pressed onto the inner contour of the lower opening groove 6 by the magnetic attraction of the magnetic block 3.

[0031] During the actual installation process, the inner skeleton 5 is placed in the casting cavity surrounded by the bottom mold 1 and the side mold 2, so that the lower end opening of the lower opening groove 6 is facing the multiple groups of magnetic blocks 3 distributed on the bottom mold 1, and then the positioning rod 4 is inserted and installed in the lower opening groove 6. Under the adsorption of the magnetic block 3, the positioning rod 4 is pressed against the inner wall of the lower opening groove 6, and during the casting process, the downward pressure is continuously maintained so that the lower end of the inner skeleton 5 is tightly pressed against the bottom mold 1, so as to achieve sealing of both sides of the inner cavity of the lower opening groove 6 during the casting process, thereby improving the matching accuracy of the imitation wood grain concrete pile after molding.

[0032] Example 2: Based on Example 1, the magnetic block 3 is fixedly installed on the bottom mold 1, and the magnetic block 3 corresponds to the lower end port position of the lower opening groove 6. A countersunk hole 7 facing the lower opening groove 6 is provided on the bottom mold 1. The magnetic block 3 is installed at the lower end of the bottom mold 1, and the magnetic block 3 is connected to the lower end of the positioning rod 4 through the countersunk hole 7.

[0033] The countersunk hole 7 is provided to facilitate the installation of the magnetic block 3 at the lower end of the bottom mold 1. At the same time, the countersunk hole 7 is used to connect the lower opening groove 6 and improve the strength of the magnetic attraction. Therefore, during the installation process, the magnetic block 3 and the positioning rod 4 are used for cooperative adsorption, so that the magnetic block 3 can be automatically fixed in the countersunk hole 7.

[0034] Example 3: Based on Example 1, the lower end of the magnetic block 3 is installed on the upper end of the bottom mold 1 through the rivet 8, the magnetic block 3 is opposite to the lower opening groove 6, and the magnetic block 3 fits the outer wall of the positioning rod 4.

[0035] By fixing the magnetic block 3 on the bottom mold 1 through the rivets 8, the position of the magnetic block 3 is limited, so that the magnetic block 3 and the positioning rod 4 are in contact and adsorbed, and the strength of the magnetic attraction is further improved.

[0036] Example 4: Based on Example 1, the magnetic block 3 is fixed at the lower end of the positioning rod 4, and an embedding groove 10 for fixing the magnetic block 3 is provided on the outer wall of the positioning rod 4. The bottom mold 1 is configured to be a material that can cooperate with the magnetic block 3 for adsorption or a magnetic block with an opposite magnetic pole to the magnetic block 3 is provided on the bottom mold 1.

[0037] The magnetic block 3 embedded in the positioning rod 4 is fixed on the positioning rod 4, so it can work alone to directly absorb the bottom mold 1, so as to achieve the purpose of fixed pressing, thereby locking the inner skeleton 5, or a magnetic block that interacts with the magnetic block 3 is provided on the bottom mold 1, and cooperates with the adsorption to provide a stronger locking force, so that the inner skeleton 5 is fixed more securely.

[0038] Embodiment 5: Based on Embodiment 1, a plurality of groups of magnetic blocks 3 are arranged on the bottom mold 1, the plurality of groups of magnetic blocks 3 are distributed corresponding to the positioning rods 4, the magnetic blocks 3 are arranged in sheet shape, and the plurality of groups of magnetic blocks 3 are distributed in linear point shape on the bottom mold 1.

[0039] For imitation wood grain concrete piles with a smaller length or volume, their weight after pouring is smaller, so that the impact on the inner skeleton 5 during the pouring process is smaller. Therefore, multiple groups of magnetic blocks 3 can be arranged to be distributed in a point shape on the bottom mold 1 to provide an adaptive adsorption force.

[0040] Embodiment 6: Based on Embodiment 1, the magnetic blocks 3 are in the shape of long strips, and the lengths of the multiple groups of magnetic blocks 3 are adapted to the lengths of the positioning rods 4. The positioning rods 4 are provided with multiple groups, and the ends of adjacent positioning rods 4 are cooperatively connected.

[0041] For the imitation wood grain concrete piles with a longer length, the impact of the concrete mud on the inner skeleton 5 is relatively large during the pouring process. Therefore, the magnetic block 3 is set to be a long strip to achieve full-length adsorption of the positioning rod 4. At the same time, in order to adapt to the length of the imitation wood grain concrete piles, multiple groups of positioning rods 4 that are clamped end to end can be set to achieve full-length pressing of the lower opening groove 6.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
