Claims

[Scope of utility model registration request]

An injection mold in which a product molding section is formed between a cavity die main body and a core die main body that is movable back and forth in opposition thereto, and the product molding section is filled with molten resin through a spool, a runner, and a gate. , a first slide block supported by the cavity die body so as to be movable in the same direction as the movement direction of the core die body, and having a spool formed in the same direction as the movement direction of the core die body; and the first slide block of the core die body. A second slide block is supported movably in the same direction as the moving direction of the core die body at a portion facing the second slide block, and forms a runner and a gate between the second slide block and the core die body. A holding block is arranged in between so as to be removable and to hold the first and second slide blocks immovably in the insertion position when the mold is clamped, but to be movable in the extraction position; A cylinder for moving the holding block to be moved between the insertion position and the extraction position is disposed between the first slide block and the cavity die body so as to be movable in a direction perpendicular to the movement direction of the core die body. a slide cam that moves the first and second slide blocks toward the core die body side by movement in a direction perpendicular to the core die body to cut the gate portion and spool portion of the resin; and a slide cam that is attached to the cavity die body and that is attached to the cavity die body after injection solidification. a slide cam moving cylinder for moving the slide cam, and an ejector which is provided to be able to press the resin runner part from the second slide block side and which integrally removes the gate, runner and resin part of the spool by the pressing movement after opening the mold. An injection mold characterized by comprising:
