Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a concrete prefabricated component forming mold. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. In the process of manufacturing prefabricated buildings, molds are often required for forming and fixing. However, the common mold structures on the market are relatively simple. They are all fixed molds that cannot be spliced ​​and adjusted according to user needs. Moreover, the demolding effect is relatively poor after the concrete is formed, which can easily cause damage to the concrete prefabricated components and waste resources.

[0003] The patent with application number CN202123246963.4 discloses an assembly mold for the production of prefabricated concrete components, including a mold base, and also including: a double-thread screw, which has two pieces, which are movably installed on both sides of the upper end of the mold base and are symmetrically distributed, and one end of each piece is connected to each other through a transmission sprocket and a transmission chain; a second template, which has two pieces, which are movably installed on both sides of the upper end of the mold base and are symmetrically distributed, and both ends of each piece are fixedly installed with connecting blocks, and the four connecting blocks are movably connected to the two ends of the two double-thread screws respectively; the user rotates the second rotating disc, and the second rotating disc drives the crankshaft to rotate, and the crankshaft drives the knocking plate to move up and down inside the mounting sleeve through the movable sleeve and the movable pull rod. When the knocking plate moves to the highest position, the top block is fitted with the upper end of the inside of the mold base, and the mold is easily demolded under the repeated movement of the knocking plate.

[0004] However, when this patent is used, it is difficult to demould the mold only by relying on the knocking plate and the top block. Instead, the pre-component inside the mold needs to be knocked to a certain distance before demoulding. Utility Model Content
