The pultruded plate product made of the composite material is widely applied to the production of wind energy blades due to the advantages of strong mechanical property, light weight and the like. Pultruded panels are generally manufactured by laminating and layering fiber materials and then adopting a resin vacuum infusion mode, but after the resin is cured and formed, the pultruded panels are not convenient to demould. Therefore, in order to facilitate demolding after the completion of the production of the pultruded panel, the surface of the pultruded panel is usually covered with a demolding structure. Common demoulding products comprise demoulding cloth and demoulding agents, and the demoulding products are covered on the surface of a pultruded plate so as to facilitate the rapid demoulding of the formed pultruded plate. However, the existing demolded product has some problems in the using process, for example, the demolded cloth has high water absorption, which affects the quality of the pultruded panel, and ultimately affects the qualification rate of the product, and the pultruded panel after being torn off the demolded cloth can form a rough surface, and the pultruded panel with the rough surface needs to be processed to improve the smoothness according to the practical application. Further, the release agent affects the adhesion property of the pultruded panel and may migrate to the surface of the pultruded panel with time, thereby causing a risk of use.
In order to solve the problems, the utility model provides a die-formed part, which solves the problem that the yield of pultruded plates is influenced by the traditional demoulding product through the combination of a base material and a demoulding structure, ensures the smoothness of the surface of the base material and is suitable for practical use.
