Abstract
The utility model relates to an automobile instrument panel formed by gas aided injection molding, comprising an instrument panel main body and a gas aided structure, wherein the gas aided structure comprises an original air passage. The gas aided structure further comprises an assistant air passage and an air outlet. The air outlet is arranged on the end surface of the instrument panel main body matched with the end cover of a peripheral instrument panel. The assistant air passage is extended to one end of the original air passage from the air outlet and is communicated with the original air passage. The utility model realizes the function of gas aided flash and increases the adjusting space of the injection molding technology by optimizing the gas aided structure of the product via adding assistant air passage. The utility model makes a greater contribution to the aspects for optimizing the appearance of the gas aided area of the product and increasing the space of the injection molding technology. The novel gas aided structure in the utility model can also be applied to optimizing the air passage design structure of the gas aided injection molding product which is hard to arrange the flash structure and which avoids large corner structure.
Description
Technical field
The utility model relates to the Manufacturing Technology for Automotive Parts field, relates in particular to a kind of Automobile instrument of gas-assisted injection molding moulding.
Background technology
Along with the raising of expanding economy and living standards of the people, increasing choose automobile is also had higher requirement to automotive trim especially the attractive in appearance of instrument carrier panel moulding as walking-replacing tool simultaneously.
The wall thickness of general Automobile instrument body product is many to belong to thin-walled injection moulding at 2～5mm, but sometimes because bigger wall thickness can appear in the needs of product structure, generally takes the auxilliary Shooting Technique of air just can guarantee product appearance.Gas-assisted injection molding technology is the product wall thickness place " to be hollowed out " be designed to air flue, in the process of injection moulding, charges into unreactable gas, thereby guarantees the Forming Quality of the big goods of wall thickness variation; Generally speaking, all can the flash structure be set at the filling end of air flue, as shown in Figure 1, gas gets into air flue 2 ' from admission port 3 ', comes out from air extractor duct 1 ' at last, and this air extractor duct 1 ' also is a flash structure simultaneously; The flash structure is set promotes gas penetration, increase air flue and empty rate, eliminate sluggish trace, the stable article quality; Usually in order not influence outward appearance, admission port and air extractor duct be not all on the appearance of part.
As shown in Figure 2, in the prior art, the air flue 4 ' that runs into the instrument carrier panel product design sometimes is positioned at the centre portion of part; Be air flue 4 ' and product end surface 7 ' disconnected situation; Therefore, make mould can't arrange the flash structure, thereby caused following problem:
1, is swollen with; In the gas filling process, gas passage stops up, and gas can't be discharged, and because of the release of high pressure gas, the product air flue is swollen with after the die sinking;
2, corner effect; In the gas flow process, when running into corner, gas turns near the inboard, and outside corner produces shrink because of heavy wall;
3, sluggish trace; In the gas filling process, because airway pressure skewness or local materials flow are blocked, the too high surperficial speck that causes of material temperature.
In view of the foregoing, press for the Automobile instrument of a kind of novel gas-assisted injection molding moulding of research and development at present, to satisfy the requirements for quality of user to it.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of Automobile instrument of gas-assisted injection molding moulding, is beneficial to the prolongation die life to optimize mould structure, and guarantees products gas-assist zone good looking appearance.
The Automobile instrument of the described a kind of gas-assisted injection molding moulding of the utility model; It comprises an instrument carrier panel body and the auxilliary structure of a gas; Wherein, the auxilliary structure of said gas comprises an original air flue, and the auxilliary structure of said gas also comprises an auxiliary port and an air extractor duct; On the end face that is complementary with peripheral instrument carrier panel end cap that said air extractor duct is arranged on said instrument carrier panel body, said auxiliary port extends to an end of said original air flue and is communicated with this original air flue from this air extractor duct.
In the Automobile instrument of above-mentioned gas-assisted injection molding moulding, be provided with the gap between the B face of said auxiliary port and said instrument carrier panel body.
In the Automobile instrument of above-mentioned gas-assisted injection molding moulding, said original air flue is arranged in the midway location of said instrument carrier panel body.
Owing to adopted above-mentioned technical solution, the utility model has not only been optimized the auxilliary structure of gas through increasing auxiliary port, and when having realized the auxilliary flash function of gas, also has following advantage:
A. improve the product appearance quality; Increase guaranteed behind the auxiliary port air flue moulding straight along and possess the flash function, prevented that effectively speck, percussion mark from appearring in the auxilliary region surface of gas, the auxilliary common apparent amount of apparent defect product of gas such as reprint books in a reduce format is able to obvious lifting;
B. increase the Shooting Technique space; After the optimization more rationally and the air passage structure that possesses the flash function help on the Shooting Technique adjustment for intake pressure and intake period point; Increased the space adjusted of Shooting Technique greatly, for follow-up steady production and higher product qualified rate are laid a good foundation;
C. optimize mould structure; The fractal area place of the mould that air flue is extended is beneficial to design of flash designs simplification and processing; Mould structure has been optimized in the adjustment of auxiliary port greatly; Air flue zone cavity pressure compared with the original design scheme is present is lower more average, is beneficial to the service life that prolongs mould.
