Description

Technical Field

[0001] This invention relates to molds for precast concrete components, and more particularly to a demolding device for precast concrete component molds. Background Technology

[0002] For small precast components, traditional production methods typically use single plastic molds, with manual demolding achieved by striking the mold. This is time-consuming, labor-intensive, and prone to mold breakage, affecting the quality of subsequent components. Furthermore, the molds wear out quickly and have a short lifespan. In some newer small precast component production lines, a flipping mechanism is used to rotate the mold so that the opening faces downwards. Demolding is then achieved through the impact generated by lifting and then naturally falling. This method places very high demands on the mold material and rigidity, resulting in poor demolding stability, significant fluctuations in the number of impacts required for demolding, and a high risk of damaging both the mold and the component. Therefore, this applicant proposes an improved concrete precast component mold. A push rod is added to the bottom of the mold base. After the component is formed, the push rod pushes the component out of the mold cavity to achieve demolding. This demolding method is stable, smooth, and less prone to damage to the mold and the component. How to achieve automated and continuous demolding using the push-type mold is a further technical problem to be solved. Summary of the Invention
