[0002] Blade casting molds generally use two core boxes to make sand cores for casting. Because blade castings have a curved surface structure and large warpage, wooden core boxes are used. The surface area of the core box is formed by stacking wood materials and used around Wooden baffle reinforcement, see figure 1 As shown; for blade castings, the cost of the core box accounts for about 20% of the production cost of the entire casting; the production cycle of the core box by this method is at least 30 days, the mold making time is too long, and the wood The mold surface formed by the active surface part is easy to deform after use, which seriously affects the quality of the casting and the delivery cycle

Embodiment Construction
[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0028] A blade casting mold, please refer to the attached figure 2 shown, including core box molds, see attached Figures 3 to 6 As shown, the core box mold includes a core head structure 100 and a movable surface structure 200. The core head structure 100 is used to form the peripheral frame of the core box mold, and the movable surface structure 200 is used to form the profile of the core box mold. The surface matches the contour surface of the blade; the...

The invention belongs to the technical field of casting molds, and particularly relates to a blade casting mold and a manufacturing method. The blade casting mold is mainly formed by assembling a corehead structure and a movable surface structure, so that a core box mold is high in strength, stable in structure and capable of being repeatedly used; the molded surface of the core box mold formed by resin sand filled between line templates is not prone to deformation and is easy to repair after being damaged; and by the adoption of the technical scheme, operation is easy, materials are saved, the cost can be reduced by 60%, and the manufacturing period is shortened by 70%.
