Description
Technical field
The present invention relates to technique for aircraft composite technological equipment for making technical field, especially a kind of sectional composite material
Molding die.
Background technique
Composite material shaping mould (hereinafter referred to as " molding die ") is also wanted other than the type face required precision of working region
It asks and has good air-tightness.Oversize molding die needs to be segmented due to being limited by the effective working size of process equipment
Individually processing, is assembled into entirety, common assembly and connection method are as follows: pin positioning is bolted, and passes through silicon at the docking of type face
Rubber strip sealing, with the precision in guarantee type face and airtight.Using the molding die of above-mentioned assemble method, as multiple thermal cycle makes
With silicon rubber bar aging, airtight failure needs to dismantle molding die replacement silicon rubber bar, re-assemblies use, dismounting repeatedly
Molding die process is cumbersome, and can adversely affect to type face precision.In response to this, it needs to find a kind of novel
Oversize molding die sectional method, to meet technique for aircraft composite technological equipment for making stabilization, reliable demand.
Summary of the invention
To achieve the above objectives, the present invention, which adopts the following technical scheme that, is achieved:
A kind of sectional composite material shaping mould, including multistage segmented die, positioning pin and connecting pin, feature exist
It is tower structure in segmented die, segmented die end is equipped with buttcover plate, and ventilation hole, every two sections of segmentations are evenly equipped on buttcover plate
After mold docking, each ventilation hole surrounding forms welding step surface on buttcover plate, and ventilation hole is surrounded by location hole and connecting hole
And multistage segmented die is accurately positioned by combination by positioning pin and connecting pin and is fixed together, after the docking of multistage segmented die
Welding step surface, positioning pin and connecting pin and buttcover plate junction carry out welding and form molding die.
The advantage of the invention is that comparing common assembly and connection method, avoids sectional and answer material mold and tear open repeatedly
Dress, can steadily in the long term, reliably use.With practical value.
The present invention is described in further detail with reference to the accompanying drawings and embodiments.
Detailed description of the invention
Fig. 1 molding die stepwise schematic views
Fig. 2 molding die positioning method schematic diagram
Fig. 3 molding die connection type and welding step surface schematic diagram
Ventilation hole schematic diagram schematic diagram at Fig. 4 molding die buttcover plate
Explanation: 1, the first segmented die is numbered in figure；2, the second segmented die；3, positioning pin；4, connecting pin；5, first pair
Fishplate bar；6, the second buttcover plate；7, ventilation hole；8, step surface is welded.
Specific embodiment
By taking two sections of assembled formation molds as an example, illustrate specific embodiment.
Referring to Fig. 1-4, a kind of sectional composite material shaping mould, including the first segmented die 1, second are segmented mould
Have 2, positioning pin 3, connecting pin 4, the first segmented die 1, the second segmented die 2 are tower structure, 1 end of the first segmented die
Head is equipped with the first buttcover plate 5, and 2 end of the second segmented die is equipped with the second buttcover plate 6, on the first buttcover plate 5 and the second buttcover plate 6
It is evenly equipped with ventilation hole 7.It is every on the first buttcover plate 5 and the second buttcover plate 6 after first segmented die 1, the docking of the second segmented die 2
A 7 surrounding of ventilation hole forms welding step surface 8, and ventilation hole 7 is surrounded by location hole and connecting hole and by positioning pin 3 and connection
First segmented die 1 and the second segmented die 2 are accurately positioned combination and are fixed together by pin 4, the first segmented die 1 and second point
Section die 2 dock after welding step surface 8, positioning pin 3 and connecting pin 4 and the first buttcover plate 5,6 junction of the second buttcover plate into
Row welding forms molding die.Airtight welding at segmented die docking guarantees airtight；Positioning pin 3 and the first segmented die 1,
2 buttcover plate of two-section mold is interference fit, guarantees that the relative position between segmented die is accurate；Connecting pin 4 and first point
Section die 1,2 buttcover plate clearance fit of the second segmented die.Positioning pin 3,4 quantity of connecting pin and position Synthesis consider that tooling is big
Small and molding die force-bearing situation.
