Description

Technical Field

[0001] The utility model relates to a steel mould, in particular to a steel mould for a reinforced concrete drainage pipe, belonging to the technical field of drainage pipe production. Background Art

[0002] In the prior art, the utility model with publication number 202121695585.5 discloses a reinforced reinforced concrete drainage pipe steel mold. By setting a smearing device, the cotton cloth is fixed to the surface of the groove plate by means of bolts, sufficient engine oil is injected into the capsule bottle, and the two limit plates are clamped into the sides of the lower template. The groove plate is loosened. At this time, the groove plate will be tightly attached to the inner wall of the lower template under the action of the elastic force of the first spring on the limit plate. The capsule bottle is clamped in the position between the elastic cloth and the groove plate to fix the capsule bottle, thereby avoiding the problem of the capsule bottle shaking on the inner wall of the groove plate. At this time, the capsule bottle is pressed, and the engine oil in the capsule bottle will drip onto the inner wall of the lower template through the dropper nozzle in the hose. In the process of the dropper dripping the engine oil, the two limit plates slide, and the groove plate will move relative to the lower template. The cotton cloth on the groove plate will evenly smear the engine oil on the inner wall of the lower template, thereby achieving the effect of quickly smearing the inner wall of the lower template. The working efficiency of the staff is improved. By setting the connecting device, when the staff needs to splice the lower template and the upper template, they directly insert the pin into the two close reserved holes of the upper template and the lower template, and first insert the side with the inclined surface of the inclined clamping block on the inner wall of the limiting ring into the surface of the pin. When the inclined clamping block moves to a position corresponding to the clamping groove on the clamping pin, the inclined clamping block will be clamped into the inner wall of the clamping groove by the elastic force of the second spring on the inner wall of the limiting ring, thereby achieving the effect of quickly connecting the upper template and the lower template. By pulling the two pulling blocks away from each other, the limiting ring can be removed from the surface of the clamping pin. The straight triangular prism structure of the inclined clamping block has an irreversible effect during the movement of the surface of the clamping pin. By setting the connecting device, the problem that the upper template and the lower template need to be connected by nuts by continuously turning the nuts to splice the two is avoided, thereby improving the working efficiency of the staff.

[0003] Similar to the above application, there are still some shortcomings:

[0004] 1. After the steel mold is closed, the inside of the steel mold cannot be cleaned, which affects the application effect of the release agent. In addition, when pouring concrete and controlling the rotation of the steel mold by a centrifuge, other equipment is needed to perform the scraping operation, which is inconvenient to operate;

[0005] 2. It is impossible to make corrections during the mold closing process, and it is difficult to align the mounting holes. In addition, multiple sets of fasteners need to be removed separately during the disassembly process, which is time-consuming and laborious.

[0006] Therefore, a reinforced reinforced concrete drainage pipe steel mold is designed to optimize the above problems. Utility Model Content

In addition, a second scraper is slidably provided on the first scraper, so that when the first scraper is adjusted to the bottom of the steel mold during use of the device, the second scraper automatically moves down due to power and fits with the inner wall of the steel mold. By rotating the steel mold, the inner wall of the steel mold can be cleaned, ensuring the release agent smearing effect, and when the first scraper is adjusted to the top of the steel mold body, the second scraper moves down to the bottom of the first scraper, and the first scraper can be used to scrape the inner wall of the drain pipe flat during the molding process, thereby improving the functionality of the device, and by providing trapezoidal blocks at both ends of the lower ear plate and limiting grooves at both ends of the upper ear plate, when the templates are engaged with each other, automatic correction and limiting can be performed, and mold closing is more convenient.

[0027] After the lower formwork 1 and the upper formwork 2 are molded together, the slider 5 is stuck in the annular groove 4, and the first scraper 6 is inserted into the steel mold laterally. The slider 5 and the first scraper 6 are adjusted to the inner bottom of the steel mold. At this time, the second scraper 10 is subjected to its own gravity and the gravity applied by the mounting plate 8, compressing the first spring 9, and the bottom of the second scraper 10 is fitted with the inner side of the steel mold. Then, the rotation of the steel mold is controlled to clean the inner side of the steel mold, and then a release agent is applied to the inside of the steel mold, and then a steel skeleton is implanted into the inside of the steel mold, and the steel mold is placed on a centrifuge, and concrete is added to the inside of the steel mold. At this time, the slider 5 and the first scraper 6 are adjusted to the top of the steel mold, and the second scraper 10 is retracted to the bottom of the first scraper 6 under the influence of gravity, and then the position of the first scraper 6 is fixed. In the process of centrifugal force controlling the rotation of the steel mold, the first scraper 6 is used to scrape the concrete flat to ensure the flatness of the inner wall of the water pipe. After the concrete pouring is completed, the first scraper 6 is pulled out, and then the steel mold is stored in the concrete for natural drying and forming;
