Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe production equipment, in particular to an open circular outer mold for a pipe mold. Background Art

[0002] In the existing production process of concrete pipes, manual high-altitude operations are required to manually lock and loosen the opening and closing die bolts. And due to the structural limitations of the mold, it is impossible to set up a high-altitude safety operation platform, resulting in high labor intensity and safety hazards during the disassembly and assembly of the mold in high-temperature and high-altitude operations after curing. Summary of the Invention

[0003] The purpose of the utility model is to provide an overall outer mold structure and a method for rotating and opening / closing to form a rotation axis, enabling the mold to achieve rapid opening and closing of the mold through the designed rotation axis.

[0004] To solve the above technical problems, the utility model provides an open circular outer mold for a pipe mold. A locking mechanism is provided at the opening / closing port of the open circular outer mold. A longitudinally extending slender stiffness weak area is provided along the length direction of the open circular outer mold. The open circular outer mold rotates and opens / closes with the area center of the slender stiffness weak area as the designed rotation axis center. When the locking mechanism is locked or opened, the open circular outer mold rotates around the rotation axis center under the action of the locking mechanism to achieve the opening and closing of the mold.

[0005] Outer mold stiffness structure plates extending along the length direction of the outer mold are provided on both sides of the slender stiffness weak area. A number of reinforcing ribs are provided on the open circular outer mold, and the outer mold stiffness structure plates and the reinforcing ribs are connected into one body. Since the outer mold stiffness structure plates are provided at other positions of the outer mold, compared with the strength of the overall mold, there are no outer mold stiffness ribs in the slender stiffness weak area, thus naturally forming a weak area. When an external force is applied by the locking mechanism or the external force of the locking mechanism disappears, the open circular outer mold will inevitably rotate along this area due to the elasticity of the material.

[0006] Preferably, a rotation limit structure is provided on the outer mold stiffness structure plate. The rotation limit structure limits the opening / closing angle of the open circular outer mold to prevent the open circular outer mold from opening too wide when the mold is opened.

[0007] Preferably, the rotation limit structure includes two symmetrically arranged limit blocks. The two limit blocks are respectively arranged on the opposite sides of the two outer mold stiffness structure plates, and the contact surfaces of the two limit blocks are both inclined surfaces; when the two limit blocks come into contact with each other, the maximum opening angle is reached, realizing the function of opening limit. When the locking mechanism is opened, the open circular outer mold rotates around the rotation point under the action of the locking mechanism. When the two limit blocks come into contact with each other, the maximum opening angle is reached, realizing the function of opening limit.

[0008] Preferably, there are multiple designed rotation shafts, which are arranged on both sides in opposite directions at the opening.

[0009] Preferably, there is 1 designed rotation shaft, which is arranged opposite to the opening.

[0010] Preferably, the locking mechanism includes multiple screw rods arranged at intervals along the length direction of the outer mold of the opening circle, and diamond joint members running on each screw rod respectively; the symmetric two ends of the diamond joint member are respectively connected to the outer mold of the opening circle; positive-thread bushings and reverse-thread bushings are respectively arranged at both ends of the screw rod; when the screw rod rotates forward, the positive-thread bushing and the reverse-thread bushing approach each other, so that the two ends of the diamond joint member connected to the outer mold of the opening circle move away from each other, thereby making the opening in an open state; when the screw rod rotates in reverse, the positive-thread bushing and the reverse-thread bushing move away from each other, so that the two ends of the diamond joint member connected to the outer mold of the opening circle approach each other, thereby making the opening in a closed state.

[0011] Preferably, the diamond joint member includes four joint plates connected end to end, and the four joint plates are sequentially rotatably connected through pin shafts.

[0012] Preferably, the diamond joint member is connected to the outer mold of the opening circle through a fixed mounting seat.

[0013] Preferably, the locking mechanism further includes a bidirectional rotation mechanism, and the bidirectional rotation mechanism drives the screw rod to rotate; adjacent two sections of the screw rods are connected through a connecting rod so that all the screw rods rotate synchronously, and the connecting rod is connected to the bidirectional rotation mechanism.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. In the present utility model, a designed rotation shaft is provided for the pipe mold, so that the mold can be quickly opened and closed through the designed rotation point; at the same time, the rotation limit structure can limit the opening angle of the pipe mold, thereby serving as a protection mechanism to enable the pipe mold to operate within the elastic deformation range and prevent plastic deformation.
