Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a small precast component mold. Background Technique

[0002] Casting, abbreviated as concrete casting, refers to the construction process of pouring the prepared concrete into the bin, leveling it, and tamping it densely. The casting requirements are continuous and uniform, and segregation of the concrete should be prevented. Tamping densely is also called "vibrating", and there are two methods: manual vibrating and mechanical vibrating. The mechanical vibrating method is commonly used in water conservancy projects.

[0003] After casting concrete components, the components need to be demolded before they can be used. However, the usual demolding method is to remove the mold or turn the entire mold to take out the components. Such a demolding method is time-consuming and laborious, and is not conducive to the second use of the mold. Content of the Utility Model

[0030] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figure 1 shown, the present utility model provides a technical solution: a small precast component mold, including: mold 1, mold 1 is arranged on a plane, mold 1 is used for loading concrete, a material pushing port and a discharging port are opened at both ends of mold 1, a threaded unit is arranged outside the material pushing port, and an outer discharging unit is arranged inside the discharging port. There are four fixing rods 11 on mold 1. The four fixing rods 11 are arranged on the top of mold 1 and are used to insert into the positioning holes opened on cover plate 2, and then are fixed by screwing the fixing buckle 12 tightly. In this way, after the pouring is completed, buckling cover plate 2 can ensure that the concrete will not deform during solidification. A fixing buckle 12 is connected to the fixing rod 11, and the number of fixing buckles 12 is also four. Threads are arranged on the fixing rod 11. The inner diameter of the positioning hole is slightly larger than the diameter of the fixing rod 11, and the fixing buckle 12 is a nut. After the cover plate 2 is sleeved on the fixing rod 11 through the positioning hole, the cover plate 2 is locked and fixed by the fixing buckle 12. The fixing rod 11 and the fixing buckle 12 are used for the installation, fixing and positioning of the cover plate 2, and are used for loading concrete to complete pouring. A cover plate 2 is arranged on mold 1. A handle 21 is arranged on cover plate 2, and positioning holes are opened on cover plate 2. The number of positioning holes is the same as that of the fixing rods 11, which is four. The cover plate 2 is used for sealing the mold 1. After the cover plate 2 is buckled, it can prevent the poured concrete from deforming during solidification. It is used to prevent the deformation of concrete pouring. It also includes: a demolding structure arranged on the mold 1, and the demolding structure is used for demolding the component after the pouring is completed.

[0032] The demolding structure includes a threaded unit and an outer discharge unit provided on the mold 1. The threaded unit transfers the component to the outer discharge unit to complete demolding. The threaded unit is used to push the component to move inside the mold 1 and push the component to the outer discharge unit. The outer discharge unit discharges the cast component outward. The threaded unit includes a carrier 3 provided on the mold 1. The carrier 3 is used to carry the threaded rod 31. The carrier 3 is triangular and fits on the mold 1. A threaded hole is provided on the carrier 3, and the threaded hole meshes with the threaded rod 31. Rotating the threaded rod 31 can move inward in the threaded hole, thereby driving the push plate 35 to move inward. The threaded rod 31 is provided on the threaded hole, and the size of the threaded rod 31 meshes with the threaded hole. The power end of the threaded rod 31 is provided with a turntable 32. The turntable 32 can drive the threaded rod 31 to rotate. The turntable 32 is used to rotate the threaded rod 31. The turntable 32 has five protrusions, which are convenient for rotating and grasping, improving the handling feel. The unloading end of the threaded rod 31 is provided with a rotating shaft 33. The rotating shaft 33 is used to dissipate the rotational force of the threaded rod 31 and only leave the inward driving force when the threaded rod 31 rotates inward to push. The threaded unit further includes a push plate 35. When the threaded rod 31 rotates inward, it drives the push plate 35 to move inward, thereby pushing the component to move towards the outer discharge unit. The push plate 35 is provided in the mold 1, and the push plate 35 meshes with the material discharge port. In this way, when pouring concrete, the concrete will not leak from the gap. The pushing surface of the push plate 35 is used to transfer the component. The pushing surface is the contact surface between the push plate 35 and the component. On the reverse side of the pushing surface of the push plate 35, there is a vertical block 34. Since the mold 1 is a trapezoidal block and the outer side is not a vertical cross-section, the vertical state can be achieved through the vertical block 34. The vertical block 34 is used to connect to the rotating shaft 33. In this way, the driving force of the threaded rod 31 can be vertically transferred to the push plate 35 horizontally to push the component to move outward. The outer discharge unit includes a movable shaft 37 provided on the mold 1. The movable shaft 37 is used to drive the flap door 36 to rotate. When the component moves, it can push open the flap door 36. The size of the flap door 36 is the same as the size of the discharge port, which can also prevent overflow during concrete pouring. The movable shaft 37 is provided with the flap door 36. The number of movable shafts 37 is at least two. The two movable shafts 37 are arranged on both sides of the bottom of the flap door 36. Such a design can also carry the component when the flap door 36 flips outward, so that the component will not directly fall to the ground after being discharged outward. A lock for the flap door 36 is provided outside the discharge port of the mold 1 to lock the flap door 36 and prevent the flap door 36 from rotating outward during concrete pouring, resulting in concrete leakage. All the movable shafts 37 are arranged mirror-symmetrically on both sides of the flap door 36.

[0033] As described above, in this embodiment, concrete is poured into the mold 1. After the pouring is completed, the cover plate 2 is positioned by the fixing rod 11, and the fixing buckle 12 is rotated into the fixing rod 11 to fix the cover plate 2, which can effectively prevent the concrete from deforming during solidification after pouring.

[0034] As described above, in this embodiment, after the concrete solidifies, the turntable 32 is rotated. The turntable 32 drives the threaded rod 31 to move inward in the carrier 3. The rotating shaft 33 effectively dissipates the rotational force of the threaded rod 31 and only leaves the inward driving force, which pushes the push plate 35 to push the cast member to the discharge port.

[0035] As described above, in this embodiment, after being pushed to the discharge port, the lock of the lockable flap door 36 is opened, and the flap door 36 rotates outward through the movable shaft 37 to open the discharge port. When the flap door 36 flips outward, it can also carry the member so that the member does not fall directly to the ground after being discharged.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
