Description

The elongated moulding of new automobile

Technical field

The utility model is related to a kind of automobile injection parts, specifically related to a kind of elongated injection parts of automobile.

Background technology

With the improvement of automotive light weight technology, the various plastic cement cast members used on automobile are more and more, for example base plate, front and rear Bumper etc., increasing using casting such as plastic cement, the connection each other of these casting is substantially and uses fastener It is attached, and these fasteners are all one-time formed when casting, so the requirement to casting is very high.The development of casting There is the history of a century, the lifting of foundry engieering has also reached suitable height, but the requirement of hot investment casting and cost right and wrong It is often high.Very, for reduces cost, many automobile component manufactures are looked forward to for requirement of the particularly for motor vehicle plastic cement casting to details Industry, reduces casting technique with reduces cost.

Plastic cement has shrinkage, in injection moulding, plastic particles is heated first and is become molten condition and is injected into mould type Chamber, then plastic parts is shaped to by cooling and shaping.Certain pressure is needed in injection, is also needed in a period of time after injection Want certain holding pressure because during cooling, the shrinkage of plastic cement can be such that material inwardly collapses, typically meat wall compared with The positions such as thick elongate strip, sharp angle long can form the contraction trace of pit shape, be called shrink, reprint books in a reduce format etc.；These automobile-used injections Part can produce to reprint books in a reduce format causes product yield bottom, and can cause the problems such as later stage assembling, plating.

Utility model content

The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of elongated note of new automobile Plastic, it has a case that elongate strip, sharp subscript plastic long are reduced to produce and reprinted books in a reduce format, the yields of product is improved, after also ensure that The assembling and plating of phase.

To achieve the above object, the utility model is using following technical scheme：It includes side plate 1 and base plate 2, side plate 1 It is integrated with base plate 2 and is molded, the thickness of side plate 1 is thicker than the thickness of base plate 2, biside plate 1 forms wedge angle 3, the inner side of wedge angle 3 The excessive place of biside plate be circular arc excessively, wedge angle outer rim be also equipped with circular arc excessively, between external arc top and interior annular top away from It it is 1.5-3 times of the width d of side plate 1 apart from the length of D from being D；

Described both sides side plate 1, base plate 2 and both sides skirt into wedge angle form cavity；

Operation principle of the present utility model：By the distance between external arc top and interior annular top it is D's in the utility model Length is 1.5-3 times of the width d of side plate 1, and wedge angle more internal than 3-6 times of prior art is small a lot, so equivalent in inner side Plastic cement amount is reduced at cavity, pressure required during injection is decreased, the phenomenon of reprinting books in a reduce format of the generation in injection moulding process is reduced, carried The yields of high product.

Specific embodiment

Specific embodiment one

Referring to shown in Fig. 1-3, the technical scheme that this specific embodiment is used is：It includes side plate 1 and base plate 2, side plate 1 It is integrated with base plate 2 and is molded, the thickness of side plate 1 is thicker than the thickness of base plate 2, biside plate 1 forms wedge angle 3, the inner side of wedge angle 3 The excessive place of biside plate be circular arc excessively, wedge angle outer rim be also equipped with circular arc excessively, between external arc top and interior annular top away from It it is 1.5-3 times of the width d of side plate 1 apart from the length of D from being D；

Described both sides side plate 1, base plate 2 and both sides skirt into wedge angle form cavity；

Operation principle of the present utility model：By the distance between external arc top and interior annular top it is D's in the utility model Length is 1.5-3 times of the width d of side plate 1, and wedge angle more internal than 3-6 times of prior art is small a lot, so equivalent in inner side Plastic cement amount is reduced at cavity, pressure required during injection is decreased, the phenomenon of reprinting books in a reduce format of the generation in injection moulding process is reduced, carried The yields of high product.

The above, is only used to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope, all should cover in the middle of right of the present utility model.

Specific embodiment two

Referring to Fig. 4, this specific embodiment is with the difference of specific embodiment one, the inner side of described wedge angle 3 The excessive place of circular arc of biside plate is provided with circular trough 3-1, the depth phase of the cavity that the depth of circular trough 3-1 is formed with biside plate Together.Other compositions and annexation are identical with specific embodiment one.

This specific embodiment can further reduce the accumulation of the injected plastics material at acute angle, reduce further injection contracting The probability of print, improves yield rate.
