Description
Technical field
The technical field of mould is the utility model is related to, is especially a kind of aircraft machine cover shell for helicopter engine
Molding die.
Background technology
The production requirement of aviation part is very high, should ensure its intensity, reduces its weight to the greatest extent again, therefore, is used for
The material requirements of aviation part is higher, most commonly acts on carbon fibre material to make, this is because carbon fiber has weight
Lighter than aluminium, intensity is but higher than steel, and has the advantages that corrosion-resistant, high temperature resistant, modulus are high.At present, the manufacture method of carbon fiber product
Have a variety of, and it is use die pressing to be most suitable for being used for make aviation part, and this method is by the carbon fibre of pre-soaked resin already
Dimension material is put into metal forming mold, is overflowed unnecessary glue after pressurization and is come, then hot setting is molded, finished product after the demoulding
Just out.But this molding die of the prior art with the following drawback that：Due to being equipped with multiple edges in molding die
Block, and usually these inserts are arranged at cavity side, therefore, when molding die molds, these inserts are easily encountered
Carbon cloth, makes carbon cloth be moved, thus, it may be difficult to carbon cloth is laid with smooth equilibrium, so as to influence product density
Uniformity, cause end properties unqualified.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and avoids carbon cloth from being moved, so as to ensure
The uniformity of product density, then ensures the molding die of the aircraft machine cover shell of end properties qualification.
In order to solve the above technical problems, the molding die of aircraft machine cover shell provided by the utility model, including upper die and lower die
And pitched roof mechanism, upper die and lower die form product cavity after molding, the formation product cavity that is laid with before carbon cloth into
Insert on type sliding block and core is detachably connected in lower die, and pitched roof mechanism is arranged in upper mold, and oblique top sliding block is positioned at paving
If in the cavity surface after carbon cloth；Molding die is equipped with multiple injecting glue points communicated with product cavity, and multiple injecting glues point
It is respectively positioned on upper mold top surface；Molding die be additionally provided with it is at least one communicated with product cavity vacuumize a little, it is described to vacuumize a position
In with the corresponding lower die bottom surface of injecting glue point.
Distribution of shapes of the injecting glue point along product, product are rectangular profile, and injecting glue point is located at the four of rectangular profile respectively
At a edge, center and at the long side center of rectangular profile；One end of all injecting glue points and the glue-feeder of molding die connect
Logical, the other end of all injecting glue points is connected with product cavity.
Described vacuumize is a little three, respectively at the both ends of the one of long side of rectangular profile and another long side
Middle；Three one end vacuumized a little are connected with the vacuum pumping pump outside molding die, and the other end is connected with product cavity.
After above structure, the utility model compared with prior art, has the following advantages that：
1) since cavity surface is higher than the top surface of product, oblique top sliding block is located above cavity surface, is so closed in upper mold and lower die
When mould, carbon cloth can't be subject to the interference of oblique top sliding block and produce offset, thus it is guaranteed that the position of carbon cloth
Stability, so as to ensure that the uniformity of product density, then ensures that end properties are qualified；
2) injecting glue point is uniformly distributed, and be ensure that sizing material can confiscate and is flowed full whole product；
3) reverse side in injecting glue face, i.e., be provided with lower die bottom surface and vacuumize a little, takes out product side while marginal not glue true
Sky, so contributes to material fully to be flowed in mold cavity, product could note each place, and note more solid.

Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
From the structure diagram of the molding die of the utility model aircraft machine cover shell shown in Fig. 1~Fig. 6, it includes
Upper mold 3, lower die 2 and pitched roof mechanism, upper die and lower die form product cavity after molding, the formation production being laid with before carbon cloth
Insert 5 on the forming slide 4 and core of product cavity is detachably connected in lower die 2, and pitched roof mechanism is arranged in upper mold 3, and
Oblique top sliding block 7 is in the cavity surface being laid with after carbon cloth.Molding die is equipped with multiple injecting glues communicated with product cavity
Point 6, and multiple injecting glues point 6 is respectively positioned on 3 top surface of upper mold.Molding die is additionally provided with least one to be vacuumized with what product cavity communicated
Point 8, it is described vacuumize a little 8 positioned at and corresponding 2 bottom surface of lower die of injecting glue point 6.
Distribution of shapes of the injecting glue point 6 along product, product are rectangular profile, and injecting glue point 6 is respectively positioned at rectangular profile
