Abstract

The invention provides a synchronous ejection method of a formed part made from composite materials. The synchronous ejection method adopts an ejector block 1, a spring 2, a mold 3, an ejector rod 4, an air cylinder 5 and an air cylinder limiter 6. The spring 2 is in a compressed state under the state of not being ejected; when the mold is opened, the un-ejected state is converted into the ejected state, and the compressed state of the spring 2 is converted into an extending state, so that the synchronous ejection is realized when the mold is opened for the formed part made from the composite materials. Through the cooperation of all mechanisms, the high-efficiency non-damage ejection of the composite materials during forming is realized. When an upper mold and a lower mold for the formed part are opened, synchronous gapless ejection is realized, and the influence on the part made from the composite materials, which is still in high temperature during ejection, is effectively avoided, so that the part made from the composite materials can be quickly demolded; therefore, the synchronous ejection method meets the requirements for the advanced forming technology of light high-strength composite materials.

Description

The synchronous extrusion method of composite formed parts
Technical field
The present invention relates to the synchronous extrusion method of a kind of composite formed parts, belong to composite formed field.
Background technology
Polymer matrix composites have higher specific strength, specific stiffness, the excellent characteristic such as impact resistance, fatigue resistance, have extensive use in fields such as automobile, track traffic, Aero-Space, engineering machinery, naval vessel, buildings.
In polymer matrix composites forming process in higher, the forming process of composite temperature material and mold temperature difference larger, forming technology requires comparatively harsh, easily eject defect in composite formed part ejection ejection process, cause product to cool the problems such as rear distortion, warpage.
Summary of the invention
The present invention is directed to the particular/special requirement that polymer matrix composites forming process ejects the demoulding, there is provided a kind of composite formed parts synchronous extrusion method, composite product can be realized thus synchronously eject when upper and lower mould die sinking, avoid ejecting defect, reduce the rear distortion of product cooling, warpage issues, thus meet the advanced forming requirements of polymer matrix composites.
The synchronous extrusion method of the composite formed parts of one provided by the invention, comprising: 1-angled slide block; 2-spring; 3-mould; 4-push rod; 5-cylinder; 6-cylinder stop, is connected with 4-push rod bottom 1-angled slide block, and 4-push rod is positioned at 2-spring inner.Before die sinking, 1-angled slide block outer surface is concordant with 3-mold outer surface, and now 2-spring is compressive state; During mould die sinking by non-top do well change into eject state time, 2-spring changes extended configuration into by compressive state, composite product realizes synchronously ejecting in die sinking simultaneously, eject rear 1-angled slide block outer surface and exceed 0.5 ~ 3cm than 3-mold outer surface, after pickup, 2-spring recovers compressive state, and 1-angled slide block outer surface is concordant with 3-mold outer surface.
Described angled slide block is identical with mold material, and angled slide block exposed face shape is square, circular or other curved-surface structures identical with ejecting position die surface pattern;
Described push rod upper end is fixedly connected with angled slide block, and lower end is fixedly connected with cylinder piston, keeps angled slide block and piston synchronous to move;
Described cylinder stop is push rod displacement device for limiting in cylinder, its effect be ensure non-top do well lower angled slide block outer surface concordant with mold outer surface, eject state under control angled slide block eject displacement.
The synchronous extrusion method of composite formed parts provided by the invention, by the interoperation of 1-angled slide block, 2-spring, 3-mould, 4-push rod, 5-cylinder, 6-cylinder stop, achieve in composite formed process, molded part is while upper/lower die die sinking, synchronous gapless ejects, effectively prevent ejection process to the impact of composite product being still in higher temperature, enable composite product fast demoulding, meet the requirement of Lightweight high-strength composite material forming technology.
accompanying drawing illustrates:
The synchronous liftout attachment non-top of the composite formed parts of Fig. 1 does well cross sectional representation.In figure: 1-angled slide block; 2-spring; 3-mould; 4-push rod; 5-cylinder; 6-cylinder stop.
The synchronous liftout attachment of the composite formed parts of Fig. 2 ejects state cross sectional representation.In figure: 1-angled slide block; 2-spring; 3-mould; 4-push rod; 5-cylinder; 6-cylinder stop.
detailed description of the invention:
In order to understand the present invention better, below in conjunction with drawings and Examples, the present invention will be further explained, but will be clear that the scope that the scope of protection of the invention is not limited to embodiment and represents.
As shown in the figure, the synchronous extrusion method of the composite formed parts of the present invention, when non-top does well, under the effect of 5-cylinder, 2-spring is compressive state, and 6-limiting cylinder locator qualification cylinder piston is in lower limit, now 1-angled slide block is concordant with 3-mold outer surface, and seamless; Composite is in a mold after shaping cooling and shaping, upper and lower mould separately, while die sinking, 5-cylinder is converted to decompression state, 2-spring becomes own extended configuration from compressive state, and 1-angled slide block drives 4-push rod setting in motion, the push rod stop motion when cylinder piston arrives 6-cylinder stop upper limit position, now 1-angled slide block outer surface exceeds 3-mould 0.5 ~ 3cm, and product ejects; After pickup, under the effect at 5-cylinder, 2-spring reverts to compressive state, 6-limiting cylinder locator qualification cylinder piston returns to lower limit, now 1-angled slide block is concordant with 3-mold outer surface, and seamless, completes the synchronous liftout attachment of composite material component one and ejects flow process.
