Specific embodiment
As shown in Figures 1 to 3, the hollow clamp-close type section mould for aluminium alloy includes die head 1 and mould to the embodiment of the present invention one
Extrusion on head, extrusion is surrounded by four side wall runners 2 and cross section is in square shape, has one group of adjacent wall runner turning
Angle junction is disconnected, and the two adjacent wall runners at least side wall runner of disconnection is outwards tilted, and the present embodiment is tilted for side,
During implementation can also both sides tilt simultaneously, tilt the first buckle runner 3 that inside stretching, extension is provided with the wall runner of side, gap with
The inside for tilting the adjacent side wall runner of side wall runner is provided with one and extends internally and turns again to the dowel for tilting side wall runner direction
Runner 4, dowel runner is provided with the first snap-fit runner 5, and the tilting side wall of extrusion profile is inwardly close to, and tilts side wall
When edge with the adjacent sidewall edge that it disconnects with aliging, the first buckle 6 is fastened with the first snap-fit 7.Tilt side wall
