PROBLEM TO BE SOLVED: To provide an injection molding die which can be miniaturized and made lightweight. SOLUTION: This injection-molding die comprises a die block 16, an ejector pin 18 which protrudes from the die block 16 to release a molded product P, ejector plates 24 and 26 which moves the ejector pin 18 between an protrusion position where the tip 28 of the pin 18 protrudes from the surface of the die block 16 to release the molded product P and a retreating position, a stopper plate 32 which is arranged to the ejector plates 24 and 26 on the opposite side to the die block 16 and controls the shift of the ejector plates 24 and 26 in a direction where the plates 24 and 26 are apart from the die block 18 and a fixed post 34 which guides the ejector plate 24 and 26 in their leaving from and approaching to the die block 16 and fixes the stopper plate 32 at a specified position to the die block 18. Both end parts 36 and 38 of the fixed post 34 are fixed inside spot-faced parts 40 and 42 formed at the die block 18 and the stopper plate 32 respectively. COPYRIGHT: (C)2004,JPO
