Tool.
Background technology
Currently, the moulding process of propeller has manual pasting forming process, resin transfer molding technique, autoclave molding work
Skill, die press technology for forming.Die press technology for forming production equipment input is relatively low, production efficiency is relatively high.
Traditional die form can cause mold raw material in pressure process excessive, and one can be formed after excessive material solidification
Hard overlap is enclosed, the removal process of this circle overlap is relatively difficult, it is common practice to manual pruning polishing, CNC milling machine milling
Processing, high-pressure water knife cutting, although these methods can achieve the purpose that deburring, the cost is relatively high for input, so
It is badly in need of a kind of quick, low-cost method removal compound propeller blade overlap convenient and simple for operation.
Invention content
To solve technical problem present in background technology, the present invention proposes that a kind of annular cuts overlap composite propeller
Compression molding die.
A kind of annular proposed by the present invention cuts overlap composite propeller compression molding die, including upper die and lower die；
Upper model cavity is equipped in the middle part of upper mold；In the outside of upper model cavity, along one the first shear knife of circle of its peripheral direction setting
Mouthful；In the outside of the first shearing edge of a knife, along one the first flash dumping chamber of circle of its peripheral direction setting；
Lower die cavity is equipped in the middle part of lower die；In the outside of lower die cavity, along one the second shear knife of circle of its peripheral direction setting
Mouthful；In the outside of the second shearing edge of a knife, along one the second flash dumping chamber of circle of its peripheral direction setting；
Under upper die and lower die closed state, upper model cavity and lower die cavity closing seam, the first shearing edge of a knife are cut with second
Cutter mouth is closed, and the first flash dumping chamber is corresponded with the second flash dumping chamber.
Preferably, under upper die and lower die closed state, upper model cavity is in heeling condition with lower die cavity.
Preferably, the thickness of knife edge of the first shearing edge of a knife and the second shearing edge of a knife is 0.2-0.5 millimeters.
Preferably, model cavity, the first shearing edge of a knife and the first flash dumping chamber are that integration is arranged.
Preferably, lower die cavity, the second shearing edge of a knife and the second flash dumping chamber are that integration is arranged.
In the present invention, when upper mold is closed with lower die, extra composite material can overflow and flow into flash dumping intracavitary；Together
When, it mutually shears and is closed between the first shearing edge of a knife and the second shearing edge of a knife, so that by answering in the composite material of spilling, cavity
Condensation material is cut off, to ensure that composite propeller automatically removes overlap in forming process；Wherein, shearing the edge of a knife with
Mold cavity is integrated design and processing, by the optimization of mold partial structurtes, eliminates the treatment process for cutting overlap, avoids adding
Work error improves the appearance and size precision of composite propeller, and production efficiency has also obtained significantly improving, and has saved big
Measure resource.

Specific implementation mode
As shown in Figs 1-4, Fig. 1 is that annular proposed by the present invention is cut in overlap composite propeller compression molding die
Mould, lower die scheme of installation；Fig. 2 is the sectional view at A in Fig. 1；Fig. 3 is that annular proposed by the present invention cuts overlap composite material spiral shell
Revolve the structural schematic diagram of upper mold in paddle compression molding die；Fig. 4 is that annular proposed by the present invention cuts overlap composite propeller
The structural schematic diagram of lower die in compression molding die.
Referring to Fig.1-4, a kind of annular proposed by the present invention cuts overlap composite propeller compression molding die, including upper
Mould 1 and lower die 2；
1 middle part of upper mold is equipped with upper model cavity 10；In the outside of upper model cavity 10, cut along one circle first of its peripheral direction setting
Cutter mouth 12；In the outside of the first shearing edge of a knife 12, along one the first flash dumping chamber 11 of circle of its peripheral direction setting；Upper model cavity
10, the first shearing edge of a knife 12 and the first flash dumping chamber 11 are that integration is arranged；
2 middle part of lower die is equipped with lower die cavity 20；In the outside of lower die cavity 20, cut along one circle second of its peripheral direction setting
Cutter mouth 14；In the outside of the second shearing edge of a knife 14, along one the second flash dumping chamber 13 of circle of its peripheral direction setting；Lower die cavity
20, the second shearing edge of a knife 14 and the second flash dumping chamber 13 are that integration is arranged；
Under upper mold 1,2 closed state of lower die, upper model cavity 10 and 20 closing seam of lower die cavity, the first shearing edge of a knife 12
It is closed with the second shearing edge of a knife 14, the first flash dumping chamber 11 is corresponded with the second flash dumping chamber 13.
In the present embodiment course of work, by composite material cast in lower die cavity 20, when upper mold 1 and lower die 2 are closed, on
Extra composite material can overflow and flow into the first flash dumping chamber 11, the second flash dumping in model cavity 10, lower die cavity 20
