Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Shown in referring to Fig.1, multilayer corrugated pipe extrusion die includes positioning plate 1, outer mouth mold 12, inner membrance core 13 and middle mold core
14, the first conveyor screw 2, the second conveyor screw 3, third conveyor screw 4, the 4th conveyor screw 5 and external mold are sequentially installed on positioning plate 1
6 are covered, is provided with runner in the channel where the first conveyor screw 2, the second conveyor screw 3, third conveyor screw 4, the 4th conveyor screw 5,
The one end in the channel where the first conveyor screw 2, the second conveyor screw 3 is arranged between middle mold core 14 and inner membrance core 13, third spiral
The one end in the channel where body 4, the 4th conveyor screw 5 is arranged between middle mold core 14 and outer mouth mold 12, and one end of inner membrance core 13 is set
It is equipped with water jacket 18, inner membrance core 13 is bolted with water jacket 18, fastens structure more, and one end of outer mouth mold 12 is provided with fixed
Type block 15, the inner cavity of shaped block 15 are provided with uniform ring rib 19, keep the shape of bellows more aesthetically pleasing.
Channel between middle mold core 14 and inner membrance core 13 is inner wall layer melt 17, is moulded by third plastic melt 10 and the 4th
Material melt 11 merges, compound using multiple material, enhances the performance of bellows, reduces the loss of material, middle mold core 14 with
Channel between outer mouth mold 12 is outer wall layer melt 16, is to be merged by the first plastic melt 8 with the second plastic melt 9, adopts
It is compound with multiple material, enhance the performance of bellows, reduces the loss of material.Gap between uniform ring rib 19 and water jacket 18 is small
In the sum of inner wall layer melt 17 and 16 thickness of outer wall layer melt, bellows can be quickly and easily manufactured.
