Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated component production, in particular to a demoulding device for a concrete prefabricated component. Background Art

[0002] Precast concrete components refer to concrete products that are processed and produced in a standardized and mechanized manner in factories. They are widely used in ports, pipelines, water conservancy and other fields. In some new small-scale precast component production lines, in order to prevent the outflow of concrete, the molds of precast components often require the bottom and sides of the precast panels to be limited and sealed. In this case, unless the side molds are removed, it is difficult to demould the precast components. After disassembly, they need to be reassembled for the next production, which is inconvenient to operate.

[0003] In the prior art, a Chinese patent document with a publication number of CN216099526U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a demoulding device for a precast concrete component mold, comprising a damping mold frame mechanism, a demoulding template mechanism and an ejection demoulding mechanism, wherein the damping mold frame mechanism comprises a supporting sleeve, a working platform and an ejection plate, a slide groove is symmetrically provided on the top of the working platform, a demoulding template mechanism is installed on the top of the working platform, the demoulding template mechanism comprises a transverse template and a handle, an adjustment rod is installed inside the slide groove through a bearing, the transverse template is screwed on the adjustment rod, a card slot is provided on one side of the transverse template, a main longitudinal template is slidably installed on one side of the transverse template, and a secondary longitudinal template is slidably installed inside the end of the main longitudinal template away from the transverse template, the device provides a function of demoulding the precast panel as a whole, the mold on the side of the precast panel can be separated by rotating the handle, and simultaneous and same-distance movement can be achieved, and the operation is simple.

[0004] In order to solve the problem that the demoulding of prefabricated components requires disassembling the mold and reassembling it during the next production, which is inconvenient to operate, the existing technology uses a method of separating the mold on the side of the prefabricated board by turning a handle. However, there is still a situation where manual operation is required to demould the prefabricated concrete components, which leads to limited manual operation strength, poor demoulding effect and low mechanization level of the device.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] The utility model provides a demoulding device for precast concrete components, which is achieved by replacing the existing handle adjustment with a longitudinal drive mechanism for control, and controlling the movement of a transverse formwork assembly through a longitudinal drive motor in cooperation with a first screw rod, and the longitudinal formwork mechanism is similar, thereby effectively realizing mechanized operation and improving demoulding efficiency.
