Phi 3350mm ellipsoidal melon petal normal hole convex hole mold and process

The invention creatively provides a phi 3350mm ellipsoidal melon petal normal hole convex hole mold. The convex hole mold comprises a convex hole device, a hydraulic system and an auxiliary support; the convex hole device comprises a hydraulic cylinder, a convex mold, a lower mold and a concave mold which are sequentially arranged from bottom to top, wherein the lower mold is used for supporting aconvex hole area of a melon petal, the convex mold and the concave mold are used for a convex hole, and the convex mold is fixed on a telescopic rod of the hydraulic cylinder; the hydraulic system isused for providing hydraulic power for the hydraulic cylinder; and the auxiliary support is arranged on one side of the convex hole device, and the auxiliary support is provided with a supporting plate used for supporting a non-convex hole area of the melon petal. According to the convex hole mold, large and expensive equipment is simplified to be simple and low in cost, so that production cost is greatly reduced. 本发明创造提供
