Abstract: A hot molding apparatus for making right and left symmetry product, and a hot molding method are provided to improve intensity of the product manufactured with the molding, and reduce inferior goods generated due to the shape transformation. The hot molding apparatus(30) is comprised of a low mold in which the working object is placed, a upper mold which is combined with the low mold and molds the working object, a cam which is interposed between the low mold and upper mold, and makes shape of the internal space of the working object, and a cooler(50) for cooling the working object. The cooler includes a cooling pipe for diversifying the texture of the working object from austenite to martensite, and a pump for supplying the cooling fluid to the cooling pipe.

Abstract translation: 提供了用于制造左右对称产品的热成型装置和热成型方法，以提高用模制品制造的产品的强度，并且减少由于形状转变而产生的劣质商品。 热成形装置（30）由放置有加工对象物的低模具，与低模具组合的上模具和加工对象物构成，夹在低模和上模之间的凸轮， 并且使工作对象的内部空间成形，以及用于冷却加工对象物的冷却器（50）。 冷却器包括用于将工作物体的质地从奥氏体分解成马氏体的冷却管，以及用于将冷却流体供应到冷却管的泵。
