To provide a rotary molding machine that is easy to manufacture.SOLUTION: A rotary molding machine is provided with a first and a second molds, a cam shaft, and a cam raceway member. The first and the second molds and the cam shaft are designed to rotate about a revolution shaft. The cam raceway member has a cam raceway. The cam shaft moves so as to follow the cam raceway along with the rotation. Along with the movement of the cam shaft, the first and the second molds are opened or closed. Assuming that the longitudinal direction of the cam shaft is a shaft direction, the angle between the shaft direction when the first and the second molds are closed and the shaft direction when the first and the second moldings are most opened is 45° or less.SELECTED DRAWING: Figure 1 【課題】製造が容易なロータリー成形機を提供する。【解決手段】本発明によれば、第１及び第２金型と、カム軸と、カム軌道部材を備えるロータリー成形機であって、第１及び第２金型及びカム軸は、公転軸を中心に回転するように構成され、前記カム軌道部材は、カム軌道を有し、前記カム軸は、前記回転に伴って前記カム軌道に沿うように移動し、前記カム軸の移動に伴って第１及び第２金型が開閉し、前記カム軸の長手方向を軸方向とすると、第１及び第２金型が閉じた時点での前記軸方向と、第１及び第２金型が最も開いた時点での前記軸方向の間の角度が４５度以下である、ロータリー成形機が提供される。【選択図】図１
