The invention discloses a mold core and a forming method thereof, a hollow variable cross-section beam structure and a forming method thereof, the mold core is used for the hollow variable cross-section beam structure, the mold core comprises a mold core body, the mold core body comprises a first mold part and a second mold part which are fixed in a butt joint mode, and the first mold part and the second mold part are both made of composite materials; the first mold part is provided with a first groove cavity facing the second mold part, the second mold part is provided with a second groove cavity facing the first mold part, and the first groove cavity and the second groove cavity form a core cavity of the mold core body. According to the structural design of the mold core, the problem that a traditional metal mold core cannot be demolded after the hollow variable cross-section beam structure is cured is solved, and meanwhile the deformation problem of the hollow variable cross-section beam structure after curing forming can be relieved.

    本发明公开了一种型芯及其成型方法、空心变截面梁结构及其成型方法,该型芯用于空心变截面梁结构,所述型芯包括型芯本体,所述型芯本体包括对接固定的第一模部和第二模部,两者均由复合材料制成;所述第一模部具有朝向所述第二模部的第一槽腔,所述第二模部具有朝向所述第一模部的第二槽腔,所述第一槽腔和所述第二槽腔形成所述型芯本体的芯腔。该型芯的结构设计解决了传统金属型芯在空心变截面梁结构固化后无法脱模的问题,同时也可缓解空心变截面梁结构固化成型后的变形问题。
