Previous compression molding, blade tip and blade root jacking block, reserve two holes by mold, by bolt by jacking block top to restraining position, tie
Structure is shown in Fig. 1.When this structure jacking block slides in mold, it is easy to appear stuck, limit in mould inside is shown in Fig. 2, Fig. 3, repeatedly
Whether after molding, there is glue residua at limit position, causes to push up not in place, and can not see and push up in place, eventually lead to blade and give up
Product.A kind of blade mold jacking block localization method is designed to solve this problem.
Summary of the invention
The purpose of the present invention: overcome the problems, such as since mold jacking block is easily stuck, it is not in place easily to push up, and use a kind of blade mould
Has jacking block localization method.
Technical solution of the present invention: a kind of blade mold jacking block localization method, the method take following steps:
1) blade mold 23 has a cavity identical with blade profile, and the carbon fibre material for making blade is placed
In in cavity, having the opening being connected with cavity on blade mold, the shape and blade tip of the cross section of the opening are horizontal
Cross sectional shape is identical；
2) mold jacking block component 4 includes positioning plate 13, connecting cylinder bar 1, connecting cylinder bar 2 12, mold jacking block two
10, mold jacking block 2 10 is column structure, one side is identical as blade tip shape, another side and blade tip cross section phase
Together；Connecting cylinder bar 1, connecting cylinder bar 2 12 are each perpendicular to mold top between mold jacking block 2 10 and positioning plate 13
Block 2 10 and positioning plate 13, and 2 10 pieces of mold jacking block and positioning plate 13 are connected；Mold jacking block component 4 is had and leaf
The opening of sharp shape same side insertion blade mold；
3) by pushing away positioning plate, so that the plane of positioning plate with blade mold there is the end face of opening to fit, guarantee leaf
The blade of sheet mold production is the length of design requirement along axial length.
The blade mold, which has, is arranged guiding bar 1, limit guiding bar 29 on the side of open at one end, for guaranteeing
Mold jacking block component is to the direction of blade mold internal motion.
There is the blade mold center of the side of open at one end outwardly projecting threaded circular mast 7 is arranged, and position
There is in the middle part of plate through-hole, the through-hole of positioning plate is covered on the bolt, then nut 6 is screwed in into the bolt, can make positioning plate to
The open end of blade mold is mobile.
There is the blade mold center of the side of open at one end installation pressure on outwardly projecting threaded circular mast 7 is arranged
Plate 5,4 uniform force of mold jacking block component when making to tighten bolt, prevents stuck situation.

Specific embodiment
The present invention will be described in further detail with reference to the accompanying drawing.
A kind of method of blade mold jacking block positioning, the method take following steps:
As seen from Figure 3, a kind of blade mold jacking block localization method is needed with flowering structure, by blade mold 23, mold jacking block
Component 4, limit guiding bar 1, limit guiding bar 29, threaded circular mast 7, nut 6, pressing plate 5 form；
Blade mold 23 is shown in Fig. 6, has a cavity identical with blade profile, will make the carbon fibre material of blade
It is placed in cavity, there is the opening being connected with cavity, the shape and blade and blade of the cross section of the opening on blade mold
Sharp cross-sectional shape is identical, plays the role of slideway；
Mold jacking block component 4 is shown in Fig. 5, including positioning plate 13, connecting cylinder bar 1, connecting cylinder bar 2 12, mold top
Block 2 10, mold jacking block 2 10 are column structure, one side is identical as blade tip shape, another side and blade tip cross section
