Description

Technical Field

[0001] The present application relates to the technical field of prefabrication of groove cover plates, and in particular to an in-situ prefabrication mould for groove cover plates. Background Art

[0002] Grooved cover molds are tools used to produce grooved covers of specific shapes and sizes. These covers are widely used in fields such as construction, water conservancy, environmental protection, highways, and municipal administration, such as drainage systems in buildings, cable trenches, water conservancy channels, and gratings in sewage treatment plants. Grooved cover molds are typically made of materials such as steel plates, which are durable and corrosion-resistant. However, current grooved cover molds are generally difficult to demold, requiring a demolding device. Existing grooved cover mold demolding devices mainly include the following:

[0003] Manual demoulding devices usually include handles, levers, slide rails and other components. By manually operating the handle or lever, the cover is ejected or pushed out of the mold using the lever principle. It is simple to operate and low in cost, but the demoulding efficiency is low and it may be more laborious for large or heavy covers.

[0004] The mechanical demoulding device includes components such as a motor, a reducer, a transmission mechanism, and a demoulding mechanism. The transmission mechanism is driven by the motor to drive the demoulding mechanism to complete the demoulding action. It has a high degree of automation and high demoulding efficiency and can handle large or heavy covers, but the cost is relatively high.

[0005] The hydraulic demoulding device uses a hydraulic cylinder or hydraulic motor to generate power, and drives the demoulding mechanism through the hydraulic transmission system to complete the demoulding action. Its demoulding force is large, stable and reliable, and it is suitable for occasions with high requirements for demoulding accuracy, but it also requires a higher cost investment.
