MOLD WITH MOVABLE CORE INSERT

Abstract

A mold includes a first board (10), a second board (20), and a core insert (30). The first board is mounted on the second board, and the core insert is slidably mounted between the first board and the second board, under the control of an adjusting apparatus (40). The adjusting apparatus includes a movable block (41), an elastic component (42), and an adjusting screw (43).

7. The mold as claimed in claim 6, wherein the driving portion includes a connecting surface, the configuring portion being connected to the connecting surface.

8. The mold as claimed in claim 6, wherein the mold includes an adjusting apparatus, the adjusting apparatus including a movable block, the movable block being movably mounted in the adjusting groove.

9. The mold as claimed in claim 8, wherein the adjusting apparatus includes an elastic component, the elastic component being a cylindrical spring, a diameter of the elastic component being larger than the diameter of the configuring portion of the core insert and less than the diameter of the driving portion.

10. The mold as claimed in claim 9, wherein the elastic component is coiled around the configuring portion of the core insert, one end of the elastic component biasing against the annular step of the core insert and another end of the elastic component biasing against the connecting surface.

11. The mold as claimed in claim 8, wherein the adjusting apparatus includes an adjusting screw, the adjusting screw is movably mounted in the adjusting hole.

12. A mold, comprising: a first board defining a containing hole and a containing groove therein, the containing groove communicating with the containing hole; anda core insert slidably mounted in the containing hole and the containing groove.

13. The mold as claimed in claim 12, wherein the containing hole is a cylindrical through hole and the containing groove is a round recess, the containing groove coaxially communicating with the containing hole, a diameter of the containing hole being less than a diameter of the containing groove, the first board having an annular step formed in an interior thereof, the annular step being located at the place where the containing hole communicates with the containing groove.

14. The mold as claimed in claim 13, wherein the mold includes a second board, the second board defining an adjusting groove and an installing groove therein, a width of the adjusting groove being larger than a diameter of the containing groove.

15. The mold as claimed in claim 14, wherein the second board defines an adjusting hole therein, the adjusting hole communicating with the adjusting groove and the installing groove, and the adjusting hole having screw threading formed therein.

16. The mold as claimed in claim 14, wherein the core insert includes a configuring portion and a driving portion, the configuring portion and the driving portion both being cylinders, the configuring portion being coaxially connected to the driving portion, a diameter of the configuring portion being equal to the diameter of the containing hole, and a diameter of the driving portion being equal to the diameter of the containing groove.

17. The mold as claimed in claim 16, wherein the adjusting apparatus includes an adjusting screw, the adjusting screw is movably mounted in the adjusting hole.

18. The mold as claimed in claim 16, wherein the mold includes an adjusting apparatus, the adjusting apparatus includes a movable block, the movable block being slidably mounted in the adjusting groove.

19. The mold as claimed in claim 18, wherein the adjusting apparatus includes an elastic component, the elastic component being a cylindrical spring, a diameter of the elastic component being larger than the diameter of the configuring portion of the core insert and less than the diameter of the driving portion.

20. The mold as claimed in claim 19, wherein the driving portion includes a connecting surface, the configuring portion being connected to the connecting surface, the elastic component being coiled around the configuring portion of the core insert, one end of the elastic component being retained by the annular step of the core insert and another end of the elastic component being retained by the connecting surface.
