The invention discloses a mesh surface demolding mechanism comprising a slide block (1) slidably connected to a mould and an oil cylinder (2) fixedly arranged on the mould, wherein a piston rod of the oil cylinder (2) is connected with the slide block (1), and the slide block (1) is provided with an inner cavity (3) in which an ejector retainner plate (4) is slidably connected; the mould is provided with a locking mechanism for locking the ejector retainner plate (4); an unlocking mechanism controlled by the stroke of the slide block (1) is arranged between a locking block (7) and the slide block (1); inward depressions (11) are formed in two sides of the slide block (1), through holes (12) are also formed in two sides of the slide block (1) and are communicated with the inner cavity (3), and the sides, close to the oil cylinder (2) of the through holes (12), are overlapped with the middles of the inward depressions (11); and the ejector retainner plate (4) is provided with limiting blocks (13) corresponding to the through holes (12) one to one, and the limiting blocks (13) are located in the through holes (12). Compared with the prior art, the mesh surface demolding mechanism has the characteristics that the success rate for demolding mesh surface products is greatly increased, and the product cost can be greatly reduced.
