Dynamic hinge, support chip are connected by hinges.
Further, the H-shaped shape of the support chip is H-shaped support chip, and H-shaped support chip is descended in the height direction in both ends
Between position respectively open a rectangular channel, rectangular channel groove height h is 0.2H, and width N is (0.1-0.2) H, wherein H is H-shaped support chip
Height.
Further, the H-type support chip width L is (0.8-1.0) H, and thickness B is 4-6mm, wherein H is H-shaped support
The height of piece.
Further, the hinges include two limitation folding angles be 0~120 degree hinges and four it is general
Logical moveable hinge, 0~120 degree of the hinges are mounted on regular hexagon diagonal position.
Further, the foldable support device component is connected with each other by spot welding constitutes honeycomb support dress side by side
It sets, to obtain the honeycomb support device of different size or structure.
Compared with prior art, the beneficial effects of the present invention are:
1. honeycomb support device uses support device regular hexagon honeycomb, bending strength is big, and bearing capacity is high,
It can effectively bear the pressure that upper die and lower die are subject to, eliminate not high unfavorable of bring intensity due to reducing cooling water channel wall thickness
It influences.
2. honeycomb support device uses support device regular hexagon honeycomb, support device material is greatly saved
Use, reduce economic cost.
3. foldable support device is connected with each other by hinges, the function of folding is realized, convenient for storage and is carried,
Save production space.
4. honeycomb support device can change honeycomb support by adjusting regular hexagon supporter number of components
The overall dimensions of device change beam overall size by adjusting the number of foldable support device to adapt to the cooling of different scales
Device reduces economic cost.
5. the device on the one hand it is foldable, on the other hand can transverse direction and longitudinal direction increase number to be adapted to different size water channels.
