MOLDING MACHINE

PROBLEM TO BE SOLVED: To provide a molding machine in which a simple configuration can be used to adjust molding die-clamping force with ease, without providing expensive sensors such as molding die-clamping load cells.SOLUTION: A control device 8 is provided with a molding die-clamping force determination mode. When the molding die-clamping force determination mode is selected, the control device 8 drives a molding die-clamping unit 3 to clamp a molding die device 5 with a predetermined molding die-clamping force, and subsequently drives an ejection mechanism 6 to press, at a constant torque, against a mating surface 15a of a fixed-side molding die 15, a product push-out member (a return pin 45, an ejection plate 50 or the like) provided to the ejection mechanism 6. An injection unit 4 is subsequently driven to inject a molding material into a molding die cavity 17 and fill the cavity therewith. An operation state of the ejection mechanism 6 during the injection is displayed on a display device 7, and suitability/non-suitability of the molding die-clamping force is determined. 【課題】型締ロードセル等の高価なセンサ類を備えることなく、簡易な構成で型締力の調整を容易に実行可能な成形機を提供する。【解決手段】制御装置８に、型締力判定モードを備える。型締力判定モードが選択されたとき、制御装置８は、型締ユニット３を駆動して金型装置５を予め定められた型締力で型締した後、エジェクト機構６を駆動して、当該エジェクト機構６に備えられた製品押し出し部材（リターンピン４５又はエジェクトプレート５０等）を、固定側金型１５の合わせ面１５ａに一定トルクで押し付ける。次いで、射出ユニット４を駆動して金型キャビティ１７内に成形材料を射出・充填し、そのときのエジェクト機構６の動作状態を表示装置７に表示して、型締力の適否を判定する。【選択図】図３
