Outer die device capable of automatically opening and closing

Abstract

The invention discloses an outer die device capable of automatically opening and closing and relates to a forming die for producing concrete pipelines, in particular to improvement on a concrete pipeupright outer die automatic opening and closing device. According to the outer die device capable of automatically opening and closing, the size of a locking force arm is reduced, thus the outer die locking can be effectively achieved, and flash lines are prevented from appearing on the appearance of a pipeline. The outer die device comprises an outer die barrel; a closing seam which is long frombottom to top is formed in the outer die barrel in the axis direction; the outer die device further comprises a new left door sheet, a new right door sheet and a door-opening locking mechanism; and apin shaft penetrates through push-pull outer groove steel, opening-closing push-pull beams, fixed inner groove steel and the new left door sheet from the outer side of the push-pull outer groove steeltill the pin shaft penetrates through the new right door sheet finally, and the tail end of the pin shaft is detachably connected to the new right door sheet through a lock bolt. By means of the outer die device capable of automatically opening and closing, the problem of poor locking effect of an existing outer die is solved, and the flash lines are prevented from being formed at the joint seamsof the outer surface of the pipeline during pipeline production.

Description

technical field [0001] The invention relates to a molding die for producing concrete pipes, in particular to the improvement of an automatic opening and closing device for a vertical outer mold of a concrete pipe. Background technique [0002] In the current production process of concrete pipes, there are radial extrusion, mandrel vibration, centrifugal process, suspension roller process, vertical vibration, etc. The vertical vibration process is popular in China due to its convenient production and strong versatility. Many manufacturers are used, especially when producing large-diameter tube cores, the vertical vibration process has irreplaceable advantages. [0003] At present, the external mold opening and closing of the vertical vibration process are all manual solutions, manual opening and closing, manual locking, such as Figure 5-7 As shown, the outer mold device includes an outer mold barrel 101, an original left door panel 102, an original right door panel 103 and a...

AI Technical Summary

Problems solved by technology

[0004] 1. The labor intensity of workers is high and the safety is not high;

[0005] 2. The versatility is not strong, and it is impossible to improve production efficiency by assembly line production;

[0006] 3. The locking screws need to be replaced frequently, and the production cost is high

[0008] However, in actual use, due to the long curing time of the concrete material (generally up to 6-12 hours), in the early part of the curing cycle, due to the large static pressure formed by the liquid (viscous) concrete on the outer mold wall, the outer mold joint position to achieve locking hooks (such as Figure 8 shown) the force arm L' for locking is relatively large, which makes the locking effect not good
