Description
Technical field
The present invention relates to composite processing field, be specifically related to a kind of ejector and application.
Background technology
At present, general long purlin shaping mould adopts invar steel matter, and because invar steel has the hardness similar with steel, have than aluminium, thermal coefficient of expansion that steel is less, closest to the thermal coefficient of expansion of composite, be optimal mold materials simultaneously.But invar steel long purlin forming frock involves great expense, and therefore protects long purlin forming frock in knockout course, and ensures that product internal soundness is extremely important.But for large scale wallboard long purlin class part, its complex structure, length longer (the longest close to 10m), quantity is more, in large-scale knockout course, often because frock is knocked improper, directly affect the quality of part, seriously cause part layering, the generation of the defects such as space, causes part to pay, and causes the gross distortion of frock own what is more, cause the defects such as irrecoverable, cause great amount of cost to waste.
Go back some wallboard long purlin class part at present in the process of the long purlin demoulding, under the blank of long purlin, sleeping limit is often turned on termination, both sides, wrap long purlin shaping mould and cause demoulding difficulty, therefore the mode of directly knocking long purlin shaping mould is adopted to carry out the demoulding, be easy to the distortion causing long purlin mould frock, go down for a long time, cause long purlin shaping mould to use the most at last, mould frock is reprocessed with the expense of brand-new huge.Also some other forms of shaping mould, this kind of abnormity such as such as taper, A font, arc, counterfort shape and there is the frock form of closing in, because its special construction causes the demoulding not easily, all exercise due diligence is needed in the middle part of multiple material part, leg-of-mutton tip and end, slightly do not note just causing part rejection, cannot use, not only affect operating efficiency, also cause follow-up huge maintenance cost.
Summary of the invention
The present invention is directed to prior art Problems existing; a kind of ejector is provided; be applicable to the demoulding of composite product; be particularly useful for the demoulding of large scale wallboard long purlin class composite product; not only mould frock is protected, the quality of the inner composite product of shaping mould frock can also be ensured.This ejector structure is simple, is convenient to extensive use, utilizes this ejector to carry out the demoulding to composite product, effectively can ensure parts quality, extends shaping mould service life, not only improves demoulding efficiency, also reduce manufacturing cost and use cost.
The technical solution used in the present invention is:
A kind of ejector, for composite product is departed from from mould, comprise demoulding backboard and bolt, the edge of described demoulding backboard near bottom is provided with several through hole along its length successively, demoulding backboard, through the screwed hole effect on through hole and mould, is arranged on shaping dies by described bolt.
Described a kind of ejector, there is the demoulding backboard described in two, two demoulding backboards are also respectively equipped with pin-and-hole I, also swivel plate is provided with between two demoulding backboards, one end of swivel plate is provided with pin-and-hole II, and swivel plate, by effect and pin-and-hole II and two pin-and-holes I, is connected between two demoulding backboards by straight pin, two demoulding backboards are arranged on shaping dies by the through hole on described screw bolt passes two demoulding backboards and the screwed hole effect on mould.
Described a kind of ejector, described through hole is long through-hole, and the length direction of described long through-hole is consistent with the short transverse of described demoulding backboard.
Described a kind of ejector, described demoulding backboard is aluminum demoulding backboard.
Described a kind of ejector, the thickness of described demoulding backboard is 15-20mm.
An application for ejector, comprises the steps,
1) in knockout course, vacuum bag, even cover clamp and other auxiliary material in composite product are removed;
2) bolt is utilized to be fixed on the non-working surface of mould core mould by a demoulding backboard; Knock demoulding backboard, vibro-core mould, core and composite product are departed from.
The application of described a kind of ejector, described step 2) in utilize bolt to be connected with the non-working surface of mould core mould by two demoulding backboards; Rotate swivel plate, adjustment swivel plate relatively and the angle of composite product; Knock swivel plate, vibro-core mould, core and composite product are departed from.
The application of described a kind of ejector, described step 2) when adopting rubber hammer to knock, knock from the region of composite product thickness relative thin.
The present invention has following beneficial effect:
Ejector of the present invention can ensure the harmony with composite product, cheap, reduces costs.Mould frock is made alteration of form not to occur; be reduced to mould frock and reprocess the enormous expenditure with brand-new; the irregular surface of mould frock and composite product not only can be made to fit tightly; ensure composite product type quality, and protection mould frock surface is without prejudice.
By knocking demoulding backboard and/swivel plate in ejector; realize the knockout course of composite product, not only reach the object of protection composite product quality, also reach the object of protection mould frock; extend the service life of mould frock, reduce manufacturing cost and use cost.This ejector can, according to practical situations, adopt single demoulding backboard to use, and two demoulding backboards and swivel plate also can be adopted to combinationally use.
Through hole on demoulding backboard, by bolt, ejector is fixed in mould frock, adopt the set-up mode of slotted hole, be convenient to the upper-lower height better regulating ejector, be more conducive to this ejector and complete the demoulding in mould frock, make this ejector more flexible, convenient when applying.
For this kind of abnormity such as such as taper, A font, arc, counterfort shapes there is the mould frock of closing in; because its special construction causes the demoulding not easily; therefore the swivel plate of adjustable different angles can be adopted; can by the angle of adjustment swivel plate; carry out the demoulding of different angles; not only protect mould frock, the internal soundness of the part with closing in can also be ensured.
Ejector of the present invention and method is utilized to be applied successively to the horizontal tail wallboard long purlin demoulding of 5 frame parts and the demoulding of the long purlin of vertical fin wallboard; all realize zero-fault to pay; compared to the defect introduced in knockout course in the past; after application ejector; knockout course does not bring any impact, and implementation result is very outstanding, and stripping result is significantly outstanding; result shows that this ejector can steady production, realizes protecting tool set-up, realizes the object that large scale wallboard class long purlin part zero-fault pays.
