Description

Technical Field

[0001] This utility model relates to a modular building forming equipment, and in particular to a bottom locking device used in a modular building forming equipment. Background Technology

[0002] Modular building molding equipment (commonly known as 3D vertical mold or 3D vertical mold machine) experiences expansion force during cement setting when casting components. Therefore, it is necessary to lock the inner and outer molds to prevent component deformation or even grout leakage. Traditional modular building molding equipment uses a bottom locking device (clamping position) with a rotating body. This rotating mechanism has significant drawbacks. During mold opening, due to the expansion force, the rotating body of the bottom locking device interferes with the inner and outer molds, preventing it from resetting and easily causing locking. Furthermore, if the locking device deforms, the thickness of the bottom component may increase or grout leakage may occur. Summary of the Invention

[0003] The purpose of this utility model is to provide a bottom locking device for use in modular building molding equipment. When the mold is opened, it will not interfere with the inner and outer molds and is easy to reset, thereby effectively solving the problem of locking during mold opening.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A bottom locking device for a modular building forming equipment has two clamping mechanisms located on the left and right sides of the forming mold to lock the inner mold and the outer mold. The technical solution is that each clamping mechanism has a fixed seat, a hydraulic cylinder, a left clamping block, a right clamping block, a left connecting arm, a right connecting arm, a left connecting rod, a right connecting rod, and a support fixedly installed on the fixed seat.

[0005] In each clamping mechanism, the top end of the piston rod of the hydraulic cylinder and the bottom end of the cylinder barrel are respectively hinged to the inner ends of the corresponding left connecting arm and right connecting arm; the middle positions of the left and right connecting arms are respectively hinged to the left and right ends of the corresponding supports; the outer ends of the left and right connecting arms are respectively hinged to the non-clamping head ends of the corresponding left and right clamping blocks; the clamping head ends of the left and right clamping blocks are respectively hinged to the outer ends of the corresponding left and right connecting rods; and the inner ends of the left and right connecting rods are respectively hinged to the supports.

[0006] In the above technical solution, a preferred embodiment is that the fixed base is fixed to the foundation. The support is arranged laterally, passing through the fixed base and located above it; the hydraulic cylinder is arranged laterally and located below the support. The left connecting arm is Z-shaped, and the right connecting arm is symmetrical to the left connecting arm. The left clamping block and the right clamping block are symmetrical, and the left connecting rod and the right connecting rod are symmetrical. Both the left and right connecting rods consist of two rods, with the two rods of the left connecting rod located on the front and rear sides of the support, and the two rods of the right connecting rod located on the front and rear sides of the support.

[0007] In this invention, each clamping mechanism comprises a fixed base, a hydraulic cylinder, a left clamping block, a right clamping block, a left connecting arm, a right connecting arm, a left connecting rod, a right connecting rod, and a support fixedly mounted on the fixed base. During operation, the piston rod of the hydraulic cylinder extends outward, pushing the left connecting arm to rotate clockwise around the support, causing the end face (clamping working surface) of the clamping head of the left clamping block to be in a longitudinal position and applying a force (clamping force) to the outer mold. Simultaneously, with the aid of the reaction force of the piston rod, the cylinder of the hydraulic cylinder pushes the right connecting arm to rotate counterclockwise around the support, causing the end face (clamping working surface) of the clamping head of the right clamping block to be in a longitudinal position and applying a force (clamping force) to the inner mold, thereby locking the inner and outer molds and preventing component deformation or even grout leakage. When the mold opens, only the hydraulic cylinder needs to release pressure, causing the piston rod to retract and releasing the clamping mechanism from locking the inner and outer molds. The inner and outer molds are then in a loose state, effectively preventing locking. Even slight deformation of the components will not affect production. This invention replaces the original rotating structure with a clamping structure, preventing interference with the inner and outer molds during mold opening and facilitating easy reset, thus effectively solving the problem of locking during mold opening. Tests show that compared to related technologies, the bottom locking device of this invention improves the production efficiency of the molding die by more than 10%. Attached Figure Description

Figure 2 In the attached diagram, reference numeral B represents the outer mold, reference numeral C represents the bottom mold, and reference numeral D represents the inner mold. In each clamping mechanism A, the top end of the piston rod of the hydraulic cylinder 1 and the bottom end of the cylinder barrel of the hydraulic cylinder 1 are respectively hinged to the inner ends of the corresponding left connecting arm 40 and right connecting arm 4; the middle positions of the left connecting arm 40 and right connecting arm 4 are respectively hinged to the left and right ends of the corresponding support 5; the outer ends of the left connecting arm 40 and right connecting arm 4 are respectively hinged to the non-clamping head ends of the corresponding left clamping block 30 and right clamping block 3; the clamping head ends of the left clamping block 30 and right clamping block 3 are respectively hinged to the outer ends of the corresponding left connecting rod 20 and right connecting rod 2; and the inner ends of the left connecting rod 20 and right connecting rod 2 are respectively hinged to the support 5.

[0014] The aforementioned fixed base 6 is fixed to the foundation. The aforementioned support 5 is arranged laterally, passing through the fixed base 6 and located above the fixed base 6; the hydraulic cylinder 1 is arranged laterally and located below the support 5. The aforementioned left connecting arm 40 is Z-shaped. The right connecting arm 4 and the left connecting arm 40 are symmetrically arranged. The left clamping block 30 and the right clamping block 3 are symmetrically arranged. The left connecting rod 20 and the right connecting rod 2 are symmetrically arranged.

When the mold opens, only the hydraulic cylinder needs to release pressure, causing the piston rod of hydraulic cylinder 1 to retract and releasing the clamping mechanism from locking the inner and outer molds. The inner and outer molds are then in a loose state, effectively preventing locking. Even slight deformation of the components will not affect production. This invention replaces the original rotating structure with a clamping structure, preventing interference with the inner and outer molds during mold opening and facilitating easy reset, thus effectively solving the problem of locking during mold opening. Tests show that compared to related technologies, the production efficiency of the molding die increased by more than 10% after adopting the bottom locking device of this invention.
