Abstract
A molding die includes a fixed die, a movable die movable toward and away from the fixed die, a first slide core slidable in sliding engagement with the fixed die, and a second slide core having a presser for pressing the first slide core when the second slide core is held in pressing contact with the first slide core. The fixed die, the movable die, the first slide core, and the second slide core jointly define a cavity for molding a product. The presser includes a reactive force plate for producing reactive forces against the pressure of a molten material introduced into the cavity.
Claims8
A molding die comprising:
- a fixed die including an actuator;
- a movable die facing the fixed die and movable toward and away from the fixed die;
- a slide core slidable in sliding engagement with the fixed die;
- and
- a presser for pressing the slide core in a direction transverse to directions in which the slide core is slidable,
- wherein the presser includes a member for producing reactive forces against the pressure of a molten material, which is introduced into a cavity defined between the fixed die, the movable die, and the slide core, in order to mold a product with an undercut.
A molding die comprising:
- a fixed die including a first actuator;
- a movable die facing the fixed die and movable toward and away from the fixed die;
- a first slide core slidable in sliding engagement with the fixed die;
- and
- a second slide core disposed in a position facing the fixed die across the first slide core, and movable into and out of abutment against the movable die and the first slide core, the second slide core having a presser for pressing the first slide core in a direction transverse to directions in which the first slide core is slidable when the second slide core is held in pressing contact with the first slide core;
- the movable die having a second actuator for displacing the second slide core;
- the presser including a member for producing reactive forces against the pressure of a molten material, which is introduced into a cavity defined between the fixed die, the movable die, the first slide core, and the second slide core, in order to mold a product with an undercut.
