Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Example one

Referring to fig. 2-4, this embodiment provides a production mould for glass steel flange, including layer board 1, center tube 2 and first clamp 3, center tube 2 sets firmly in the center of layer board 1, the edge of layer board 1 is equipped with the spacing step 11 that is used for placing first clamp 3, works as when first clamp 3 is arranged in on the spacing step 11, the side of layer board 1 flushes with the surface of first clamp 3.

In this embodiment, first clamp 3 includes steel sheet 31 and first locking structure, steel sheet 31 is the circle form unanimous and have opening 32 with layer board 1 shape, first locking structure locates opening 32 department and makes the both free ends butt of steel sheet 31, the both free ends of steel sheet 31 are equipped with engaging lug 331 respectively, first locking structure locates on engaging lug 331 and makes the both free ends butt of steel sheet 31, and is specific, first locking structure including locating perforation 332 of one of them engaging lug 331, locating the screw hole 333 and the bolt 334 of another engaging lug 331, bolt 334 penetrates and screw connection with screw hole 333 by perforation 332.

Meanwhile, in order to facilitate the control of the length of the connecting pipe on the glass fiber reinforced plastic flange, the surface of the central pipe 2 is provided with a scale mark I21 along the axial direction of the central pipe, so that the material waste or the over-short disqualification caused by the overlong connecting pipe on the glass fiber reinforced plastic flange is avoided.
