Description
Technical field
The utility model relates to technical field of mold, specifically, being a kind of composite material blade compression molding die.
Background technique
Excellent characteristics are more and more wider because its is light-weight, corrosion-resistant, fatigue life is high, designability is strong etc. for composite material blade
General ground substituted metal blade becomes the important technology direction of Helicopter Development and composite material career development.Currently, domestic multiple
Condensation material blade uses co-curing die press technology for forming.
Composite material blade molding die is to realize blade aerodynamic shape, guarantees dimensional accuracy and metal lining accurate positioning
Important tooling, the frame mode of mold be the key that determine composite material blade technique preparation and demoulding difficulty or ease.
Currently, the big torsion angle changeover portion section moulding majority in composite material blade root is rectangle, advantage is composite wood
Expect that the rigidity of blade is big, intensity is high；The disadvantage is that the mold design of composite material blade is difficult, in the root of composite material blade mold
Portion, which will appear, closes angle phenomenon, is unfavorable for mold processing and blade demoulding.
The position of composite material blade root bushing is the key that influence blade power transmission and stress, in the process of technique preparation
In, because raw material gel content is unstable, fill block and bushing be bonded not tight and personnel Qi Moshi using hammer tapping operation etc. because
Element, it is easy to cause bushing locations to change and loosen, the qualification rate of composite material blade is caused to decline.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of composite material blade is provided and is molded into pattern
Tool；Molding die belongs to two chamber of a mould, using the median plane of blade leading edge and rear as die joint, is divided into upper die and lower die, lower die
It is upper that positioning pin is housed, have location hole in upper mold, when upper die and lower die mold in advance, using fastening bolt and side bumper block fastening upper mold and
Lower die.
The purpose of this utility model is achieved through the following technical solutions:
A kind of composite material blade compression molding die, which is characterized in that it includes upper die and lower die, pass through fastening bolt
Upper die and lower die are fixed with side bumper block；
Upper die and lower die are designed with the location hole of positioning bushing and sink, location hole and sagging edge chamfer；
The bushing location hole of lower die is stairstepping through-hole；
The bushing location hole of upper mold is through-hole；
Blade tip movable block and root movable block are distributed in lower die, movable block and lower die pass through positioning pin and bolt
Positioning is fixed, and is distributed with top wire hole on movable block.
The match positioning pin that uses of the bushing location hole of lower die is cup head ladder positioning pin, tapping at the top of cup head
Hole uses pin removal by taking out positioning pin when composite material blade demoulds.
Compared with prior art, the good effect of the utility model is:
A kind of composite material blade compression molding die of the utility model, by the composite material blade root of type chamber lower die and
Apical location is designed as movable block form, not only improves the processing of mold, and is conducive to composite material blade demoulding.Composite material
The positioning of blade metal lining is sunk using mold and the form of ladder positioning pin, can accurately guarantee the position of metal lining,
Positioning pin is facilitated to demould simultaneously.Improve the qualification rate of product.

Specific embodiment
A kind of specific embodiment of composite material blade compression molding die of the utility model presented below.
Embodiment 1
As shown in Figure 1, the structure of composite material blade compression molding die includes: upper mold 1, lower die 2, fastening bolt 3, side
Block 4, there are also the lifting lugs for lifting.
There are two the gap to invaginate for the edge distribution of upper mold 1 and lower die 2, are mainly used for upper mold 1 and lower die 2 and press
Bolster is fastenedly connected.
As shown in Fig. 2, the specific design form of lower die 2 of the Molding Forming of Composites mold includes, positioning metal bushing is used
Sink 5 and positioning pin 6, reduce molding difficulty blade tip movable block 7 and propeller shank movable block 8.
5 depth in lower die 2 of sinking of positioning metal bushing is 1.0mm, and the depth in upper mold 1 is 1.5mm.It is fixed
Sagging 5 diameter of position metal lining is 0.5mm bigger than the diameter of metal lining.
The edge chamfer of sink 5 and the dowel hole in lower die 2 of positioning metal bushing.
Such as Fig. 3 a, shown in Fig. 3 b, being located by connecting between blade tip movable block 7 and propeller shank movable block 8 and lower die 2
Mode is to have positioning column and threaded hole in lower die 2, has location hole and through-hole, after positioning, connect on movable block using fastening bolt.
Such as Fig. 3 a, shown in Fig. 3 b, when blade tip movable block 7 and propeller shank movable block 8 and lower die 2 are detached from, will fasten
Bolt dismantling is inserted into top wire hole using bolt, movable block is ejected.
As shown in figure 4, the positioning pin of positioning metal bushing is ladder positioning pin, head is cup head, and cup head
The tapped hole in position, using pin removal by taking out positioning pin, avoids traditional percussion mode and causes metal liner in molding
Cover the risk loosened.
Ladder positioning pin is before use, smeared on its surface uniformly using high temperature silicon fat, when molding is more easier, and uses
High temperature silicon fat fills the top wire hole of movable block, and resin inflow is avoided to cause cleaning difficult.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvements and modifications without departing from the concept of the premise utility, these improvements and modifications
Also it should be regarded as in the protection scope of the utility model.
