Claims

[Claims for Utility Model Registration] The cavity template 1 and the core template 2 are slidably moved relative to one of the templates, and both templates 1,
When both mold plates 1 and 2 are closed, the core pin 4 advances into the cavity formed by them, and when both mold plates 1 and 2 are opened, it retreats from the cavity 3. In an injection molding mold equipped with a linear motion cam 7 that controls the motion, a rolling shaft is provided at least in the portion where the linear motion cam 7 comes into contact with the follower block 11 that is integral with the core pin 4 when the core pin 4 moves backward. 12,20
An injection mold with a
