Abstract
The present invention discloses a molding system, more particularly, a shrinking type molding system comprising an outer mold, an inner mold and a first pattern layer. An adjustable gap is formed between the outer mold and the inner mold to contain a work piece therein. Furthermore, the work piece with a pattern structure on the surface thereof can be formed by the first pattern layer. The difference between the present invention and the prior art is that the molding system of the present invention is capable of optionally or simultaneously forming the pattern structure on the inner surface or the outer surface of the work piece, so as to solve the long last problem that not all the surfaces of the work piece could have the pattern structure thereon in the prior art.
Claims10
A molding system for processing a tubular work piece having an inner surface and an outer surface, the molding system comprising:
- an outer mold having a tubular shape and an inner wall;
- an inner mold configured in the outer mold, the inner mold having an outer wall facing the inner wall of the outer mold;
- and
- a first pattern layer configured on the inner wall of the outer mold or the outer wall of the inner mold;
- wherein the diameter of the outer mold can be adjusted to form an adjustable gap between the outer mold and the inner mold so as to enable the work piece to be placed into and be moved out from the gap.
