Description

Technical Field

[0001] This utility model belongs to the field of precast concrete pile production technology, specifically relating to a mold for casting precast concrete columns that is easy to adjust. Background Technology

[0002] Precast columns are manufactured in a factory or on-site. The process involves making templates to specified dimensions, pouring concrete to form the desired shape, and then using the concrete in the project once it reaches the required strength. Precast column construction is relatively convenient, but the quality of joint connections must be ensured. Compared to cast-in-place concrete columns, precast columns have lower overall integrity and require less formwork, but the alignment and connection structures are more complex, and quality requirements are stricter.

[0003] In the production of precast concrete columns, molds are required for casting. However, existing molds are all of fixed specifications, meaning that different sizes of precast columns require different molds. These molds cannot be adapted for use, thus limiting their practicality. Therefore, we propose an easily adjustable mold for casting precast concrete columns. Utility Model Content

[0004] The purpose of this utility model is to provide an easily adjustable mold for casting precast concrete columns, in order to solve the problem mentioned in the background art that molds are required for casting precast concrete columns, but existing molds are all of fixed specifications. That is to say, different specifications of molds are required for precast columns of different specifications, and the molds cannot be adapted for use, which has certain limitations in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for casting precast concrete columns that is easy to adjust, comprising several central mold bases and two end mold bases. The two adjacent central mold bases cooperate with each other, and the two end mold bases are respectively attached to the sides of the central mold bases at the front and rearmost positions and the rearmost position. The central mold base includes a lower mold shell and an upper mold shell arranged opposite to each other and attached to each other. A bracket is fixedly installed on the side of the lower mold shell, and several bolts are threaded on the bracket. Connecting seats are fixedly installed on both sides of the outer surface of the lower mold shell and both sides of the outer surface of the upper mold shell. Several connecting screws are passed through between two adjacent connecting seats and between the connecting seats and the end mold bases at the edge positions. Connecting nuts are threaded on the outer surface of the connecting screws. A plate base is fixedly installed on the side of the lower mold shell, and an assembly plate that cooperates with the plate base is fixedly installed on the side of the upper mold shell. A receiving groove is opened on the lower surface of the inner wall of the lower mold shell, and a top plate is movably arranged in the receiving groove.

[0006] By adopting the above scheme, and using two end mold bases in conjunction with several middle mold bases, the appropriate number of middle mold bases can be selected according to the specifications of the precast concrete columns, thereby improving the versatility of use, avoiding the cost of multi-specification molds, and facilitating operation and adjustment. By setting a top plate for use, after the upper mold shell is removed from the lower mold shell, the rotation of the threaded rod drives the top plate to move, which in turn pushes the molded part upward, allowing the molded part to quickly detach from the lower mold shell, improving the demolding efficiency of the molded part, and greatly enhancing the ease of operation and adjustment.

[0007] In a preferred embodiment, a sealing groove 1 is provided on the side of the connecting seat and the side of the end mold seat, and a sealing strip 1 is embedded in the sealing groove 1.

[0010] By using the above solution, the insert plate is inserted into the slot, and the card plate is engaged with the card hole, which enables a convenient assembly and locking operation between the upper and lower mold shells.

[0011] In a preferred embodiment, a spring and a telescopic rod are fixedly installed on the inner wall of the groove on the insert plate, and both the spring and the telescopic rod are fixedly connected to the card plate.

[0012] By adopting the above solution, the spring force can be used to drive the clamping plate to quickly snap into the clamping hole, improving the ease of clamping. The telescopic rod is used to guide and support the movement of the clamping plate, improving the stability of movement and preventing shaking and loosening.

[0013] In a preferred embodiment, a threaded rod is threadedly installed on the lower surface of the lower mold shell, the top end of the threaded rod is rotatably connected to the top plate, and a handwheel is fixedly installed on the bottom end of the threaded rod.

[0014] Using the above scheme, the rotation of the threaded rod can drive the top plate to move, which in turn can push the molded part in the lower mold shell to move upward quickly and detach from the lower mold shell.

[0015] In a preferred embodiment, a plurality of guide rods are fixedly installed on the lower surface of the top plate, and the guide rods slide through the lower mold shell.

[0016] Using the above solution, the top plate can move stably up and down under the action of the guide rod, without any rotation or swaying.
