Abstract
A molding die for shaping a laminated molding including a molding body and a compressible surface member laminated thereonto has centering pins for determining a position of the surface member protrudable and retractable relative to a cavity inside a die body. Accordingly, since the surface member can be accurately and easily positioned and held, position shift of the surface member can be securely prevented. Further, by sinking the centering pins before molten resin is solidified, influence by the centering pins can be eliminated.
Claims9
A molding die for making a laminated molding comprising:
- a stationary die having a stationary die plate, a stationary side advancing plate and a first retracting rod;
- a first centering pin secured to said stationary die advancing plate and protruding through said stationary die plate for maintaining a first surface member;
- and
- a movable die including a second retracting rod;
- wherein a cavity of the molding die is located between said stationary die plate and said movable die, closing of said molding die causing said second retracting rod to contact said first retracting rod and move said stationary side advancing plate to at least partially retract said first centering pin from the cavity.
A molding die for making a laminated molding comprising:
- a stationary die including a stationary die plate, a stationary side advancing plate and a first retracting rod, said stationary die plate being positioned between said stationary side advancing plate and a cavity of said mold die;
- a first centering pin secured to said stationary die advancing plate and protruding through said stationary die plate for maintaining a first surface member;
- and
- a movable die including a first movable die plate,
- wherein the cavity is located between said stationary die plate and said movable die, closing of said molding die causing said first retracting rod to contact said movable die plate to move said stationary side advancing plate and said first centering pin to at least partially retract said centering pin from the cavity.
