摘要 |
The present invention provides an injection molding die having a simplified valve gate and simplified attachment structures for the valve gate. The die includes: a first die 4 with a gate 7; a second die 20 forming, together with the first die 4, a molding cavity 23 that communicates with the gate 7; a manifold 10 containing a molding material supply path 12 communicating with the gate 7; a thermal insulation space 16 disposed between the first die 4 and the manifold 10; and a valve gate 24 disposed between the first die 4 and the manifold 10 opening and closing the gate. The valve gate 24 includes: a valve pin 25 passing through the first die 4 and the manifold 10 and opening and closing the gate 7; a sealing member 27 mounted on the manifold 10 where the valve pin 25 passes through and providing a seal between the manifold 10 and the first die 4; and a heater 29 heating the manifold 10.
