Description
Technical field
The present invention relates to composite processing field, and in particular to a kind of ejector and application.
Background technology
At present, general stringer shaping mould adopts invar steel matter, as invar steel has the hardness similar with steel, while tool
There is the thermal coefficient of expansion less than aluminum, steel, closest to the thermal coefficient of expansion of composite, be optimal mold materials.But
Invar steel stringer forming frock involves great expense, therefore protects stringer forming frock during demoulding, and ensures matter inside product
Amount is extremely important.But it is directed to large scale wallboard stringer class part, its complex structure, length longer (most long to be close to 10m), quantity
It is more, in large-scale knockout course, often because frock taps improper, the quality of part is directly affected, seriously causes part to be layered,
The generation of the defects such as space, causes part pay, and causes frock gross distortion itself what is more, causes irrecoverable grade to lack
Fall into, cause great amount of cost to waste.
, during the stringer demoulding, side of crouching under stringer blank is often in both sides for also some wallboard stringer class parts at present
Turn on termination, wrapping stringer shaping mould causes the demoulding difficult, therefore by the way of stringer shaping mould is directly tapped carries out the demoulding,
The deformation of stringer mould frock is easily lead to, is gone down for a long time, most cause stringer shaping mould use at last, shaping mould
Tool frock reprocesses huge with the expense of brand-new.The also shaping mould of some other forms, such as taper, A fonts, arch, counterfort shape
Etc. it is this kind of abnormity and with close up frock form, as its special construction causes the demoulding to be difficult, the middle part of multiple material part, three
Angular tip and end are required for exercise due diligence, slightly do not note causing part rejection, it is impossible to use, not only affect
Work efficiency, also results in follow-up huge maintenance cost.
The content of the invention
A kind of problem that the present invention is present for prior art, there is provided ejector, it is adaptable to the demoulding of composite product,
It is particularly suited for the demoulding of large scale wallboard stringer class composite product, not only mould frock is protected, moreover it is possible to
Ensure the quality of composite product inside molding die craft equipment.The ejector simple structure, is easy to extensively application, using the molding
Device carries out the demoulding to composite product, can effectively ensure that parts quality, extends shaping mould service life, not only improves demoulding effect
Rate, also reduces manufacturing cost and use cost.
The technical solution used in the present invention is：
A kind of ejector, it is for composite product is departed from from mould, including demoulding backboard and bolt, described
Demoulding backboard is sequentially provided with several through holes along its length near the edge of bottom, and the bolt passes through through hole and mould
On screwed hole effect, by demoulding backboard be arranged on shaping dies on.
A kind of described ejector, with the demoulding backboard described in two, further respectively has pin-and-hole on two demoulding backboards
I, swivel plate is additionally provided between two demoulding backboards, one end of swivel plate is provided with pin-and-hole II, and straight pin is by effect and pin-and-hole II
With two pin-and-holes I, swivel plate is connected between two demoulding backboards, it is logical on two demoulding backboards of the screw bolt passes
Hole is acted on the screwed hole on mould, and two demoulding backboards are arranged on shaping dies.
A kind of described ejector, the through hole are long through-hole, the length direction of the long through-hole and the demoulding backboard
Short transverse it is consistent.
A kind of described ejector, the demoulding backboard are aluminum demoulding backboard.
A kind of described ejector, the thickness of the demoulding backboard is 15-20mm.
A kind of application of ejector, comprises the steps,
1) vacuum bag in composite product, even cover clamp and other auxiliary materials during demoulding, are removed；
2) one demoulding backboard is fixed on the non-working surface of mould core mould using bolt；Demoulding backboard is tapped,
Vibro-core mould, makes core depart from composite product.
A kind of application of described ejector, the step 2) in using bolt by two demoulding backboards and mould
The non-working surface connection of core；Swivel plate is rotated, the relative angle with composite product of swivel plate is adjusted；Tap swivel plate,
Vibro-core mould, makes core depart from composite product.
A kind of application of described ejector, the step 2) when being tapped using rubber hammer, from composite product
The region of thickness relative thin starts to tap.
The invention has the advantages that：
Ejector of the present invention can ensure the harmony with composite product, cheap, reduces cost.Make mould
There is no alteration of form in frock, reduction mould frock is reprocessed the enormous expenditure with brand-new, not only can make mould work
Dress is brought into close contact with the irregular surface of composite product, it is ensured that composite product type quality, and protects shaping mould
Tool frock surface is without prejudice.
By tapping demoulding backboard and/swivel plate in ejector, the knockout course of composite product is realized, is not only reached
The purpose of protection composite product quality, also reaches the purpose of protection mould frock, extends making for mould frock
With the life-span, manufacturing cost and use cost is reduced.The ejector can be used using single demoulding backboard according to practical situations,
Can also be applied in combination with swivel plate using two demoulding backboards.
Through hole on demoulding backboard, is fixed on ejector in mould frock by bolt, setting using slotted hole
Mode is put, and is easy to preferably adjust the upper-lower height of ejector, is more conducive to the ejector and the demoulding is completed in mould frock,
So that the ejector using when it is more flexible, it is convenient.
For this kind of abnormity such as such as taper, A fonts, arch, counterfort shape and with the mould frock for closing up, due to which
Special construction causes the demoulding to be difficult, therefore can be using the swivel plate of adjustable difference angle, can be by the angle of adjustment swivel plate
Degree, carries out the demoulding of different angles, not only protects mould frock, it can also be ensured that the inside matter with the part for closing up
Amount.
It is applied successively to the horizontal tail wallboard stringer demoulding and vertical fin wallboard of 5 frame parts using ejector of the invention and method
The demoulding of stringer, realizes that zero-fault is paid, compared to the defect introduced in conventional knockout course, after ejector, the demoulding
Process does not bring any impact, and implementation result is very prominent, and stripping result is significantly projected, and as a result shows that the ejector can be stablized
Production, realizes protecting tool set-up, realizes the purpose that large scale wallboard class stringer part zero-fault is paid.
