Abstract
The utility model discloses a plastic air inlet manifold for automotive engines, which comprises a constant pressure cavity, a mounting base and three air inlet siphons evenly arranged between the constant pressure cavity and the mounting base. Wherein, a front end of the air inlet siphon is connected with and extended into the constant pressure cavity. A back end of the air inlet siphon is connected with the mounting base. Reinforcing ribs are arranged between the front end of the air inlet siphon and the constant pressure cavity and between the back end of the air inlet siphon and the mounting base. A circular sealing groove is positioned on an end face of an air damper for the constant pressure cavity. The utility model has the advantages of concise structure, rational arrangement and plasticizing forming. Frictional vibrating welding and ultrasonic welding connection ensures high precision and great structure strength of finished manifolds and overcomes defects of high price, heavy weight, sand hole, air bubble, etc. for finished manifolds molded with aluminum alloy.
Description
Technical field
The utility model relates to a kind of motor car engine, and more particularly, the utility model relates to a kind of plastic air intake manifold of motor car engine.
Background technique
Intake manifold is the vitals that is used for motor car engine, many generally speaking the casting with aluminum alloy material made, its structure is mainly by pressure stabilizing cavity, a plurality of intake elbows and fitting seat are formed side by side, the described pressure stabilizing cavity of upper end UNICOM of described intake elbow, the described fitting seat of lower end UNICOM of described intake elbow.The advantage of this intake manifold is: compact structure, intensity are very high, but owing to be with aluminum alloy integral cast moulding, therefore have following defective:
1. pipe is outer coarse, needs secondary operations, has increased manufacturing process, has improved manufacture cost;
2. coarse in the pipe, the inlet stream dynamic resistance is big;
3. easily form the hidden danger of quality that sand holes, bubble etc. may influence the motor usability;
4. aluminum alloy casted article, price is expensive, and quality is heavy.
The model utility content
Technical problem to be solved in the utility model, improve the above-mentioned defective that prior art exists exactly, provide a kind of and can reduce manufacturing process, reduce manufacture cost, avoid sand holes, the formation of hidden danger of quality such as bubble, the plastic air intake manifold that is used for motor car engine that alleviates product weight and make things convenient for its intake elbow rationally to distribute.
The utility model is used for the plastic air intake manifold of motor car engine, comprise pressure stabilizing cavity and fitting seat, three intake elbows of evenly arranging between described pressure stabilizing cavity and the fitting seat, the front end of described intake elbow is communicated with described pressure stabilizing cavity, and the rear end of described intake elbow is communicated with described fitting seat.
Described plastic air intake manifold by molding and forming last slice, middle sheet, interior sheet and outer plate connect and compose integral body along its curved profile that agrees with mutually by vibration friction welding and ultrasonic bond respectively.
The front end of described intake elbow extends to the inside of described pressure stabilizing cavity;
Be provided with stiffening rib between the front end of described intake elbow and the described pressure stabilizing cavity;
Also be provided with stiffening rib between the rear end of described intake elbow and the described fitting seat;
The closure end face of described pressure stabilizing cavity is provided with the circular seal groove.
The utility model compared with prior art has following beneficial effect:
1. simple for structure, distribute rationally, three intake elbows evenly arrange and with the set-up mode of described pressure stabilizing cavity and fitting seat UNICOM, can make intake manifold of the present utility model, circulating resistance is little, thereby improves the air inlet charge;
2. molding and forming, finished product accuracy is good, need not secondary operations, has not only avoided the sand holes that the aluminum alloy integral cast caused, bubble etc. may influence the hidden danger of quality of motor usability, and can make intake manifold pipe of the present utility model interior smooth, thereby reduce the inlet stream dynamic resistance;
3. overall structure adopts the burst manufacturing and vibrates the manufacture of friction welding along its curve that coincide mutually, can make intake manifold of the present utility model, increases to connect area, improves join strength;
4. between the front end of described intake elbow and the described pressure stabilizing cavity and between the rear end of described intake elbow and the described fitting seat stiffening rib being set, can increase the structural strength of the utility model intake manifold, effectively prevent its distortion;
5. the employing of engineering plastics can make intake manifold of the present utility model, on weight reduction, the basis that reduces cost, has the technical performance that can match in excellence or beauty with aluminum alloy.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done to describe in detail.
Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 show of the present utility model respectively to view respectively.
By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as seen, the utility model is used for the plastic air intake manifold of motor car engine, comprise pressure stabilizing cavity 1 and fitting seat 3, between described pressure stabilizing cavity 1 and fitting seat 3, evenly be placed with three intake elbows 2, the front end 5 of described intake elbow 2 is communicated with described pressure stabilizing cavity 1, and the rear end 4 of described intake elbow 2 is communicated with described fitting seat 3.
For the structural strength that increases described intake manifold and prevent its distortion, the utility model all is being provided with stiffening rib 6 between the front end 5 of described intake elbow 2 and the described pressure stabilizing cavity 1 and between the rear end 4 of described intake elbow 2 and the described fitting seat 3.
As seen from Figure 5, the utility model is used for the plastic air intake manifold of motor car engine, its overall structure by molding and forming last slice 8, middle sheet 9, interior sheet 10 and outer plate 11 4 parts form, described last slice 8, middle sheet 9, interior sheet 10 and outer plate 11 connect as one by vibration friction welding and ultrasonic bond along its curved profile that agrees with mutually respectively.Such setting can make the connection area of intake manifold increase, thereby improve its join strength.
Also can be found out by Fig. 5: in the utility model, the front end 5 of described three intake elbows 2 extends to the situation of described pressure stabilizing cavity 1 inside.Such set-up mode can make the connection effect more firm.
In addition, the seal groove 7 that is provided with on the closure end face of pressure stabilizing cavity described in the utility model 1 is the circular seal groove shown in Fig. 5.
Intake manifold of the present utility model, employing is with molding and forming of engineering plastics burst and the manufacture that is connected along its curved profile, having overcome prior art may influence the hidden danger of quality of usability because of the existing easy formation sand holes of aluminum alloy integral cast moulding, bubble etc., and solved cast molding be difficult to solve pipe inside and outside coarse, need secondary operations, problems such as the inlet stream dynamic resistance is big, manufacturing process is many, manufacture cost height.
Above with reference to drawings and Examples, the plastic air intake manifold that the utility model is used for motor car engine schematically describes.This description does not have restricted, and shown in the accompanying drawing also is a kind of embodiment of the present utility model.If those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the utility model creation aim, it is carried out all conspicuous modifications, all should belong to protection domain of the present utility model.
