Description
Technical field
The present invention relates to auto parts and components field, in particular to a kind of four-cylinder gasoline engine plastics
Inlet manifold air inlet lamellar body structure.
Background technology
Plastic air intake manifold is due to complex-shaped, it is impossible to one-shot forming, is substantially required for its point
Become several, every injection mo(u)lding, then use Vibration welding mode to form complete air inlet
Manifold.Being proposed and air inlet is divided into a few chip architecture, prior art proposes air inlet
Mouth is divided into four chip architectures, then carries out independent welding fabrication.Such injection molding manner can solve the problem that because of
The problem being difficult to qualified molding for the thickest product caused of lamellar body.But owing to sheet number is more, welding
Time need weld the most successively, need welding repeatedly, but welding number of times the most, welding brings
Error the biggest, the dimensional discrepancy of product can be caused to increase.It is difficult to produce the product met the specification
Product come.
In order to reduce lamellar body quantity, in theory, the structure of air inlet can be simplified as two panels.
Illustrate below in conjunction with the accompanying drawing 1 of prior art～the structure of 3 pairs of air inlets.
As shown in Fig. 1～2, the inlet structure of pressure stabilizing cavity is extremely complex, the air inlet of pressure stabilizing cavity
Mouth is the important component part of whole gas manifold inlet, time actually used, needs to ensure that pressure stabilizing cavity enters
The structure of QI KOU and size.In order to ensure to manufacture feasibility, reduce technology difficulty, ordinary circumstance
Lower whole manifold is divided into upper and lower two parts carry out being injected separately molding.Pressure stabilizing cavity air inlet is prominent
The tubular construction connected with pressure stabilizing cavity for the outside of pressure stabilizing cavity, air inlet is also classified into two parts,
The most existing upper slice 20 and existing bottom sheet 21, gas inlet end structure be provided with one for automobile its
His parts fix the ring flange 22 of connection, and ring flange 22 is positioned in existing bottom sheet 21, flange
Dish 22 is provided with annular fixed station 23 towards the one side of pressure stabilizing cavity, and fixed station 23 sidepiece sets
It is equipped with a lap welding and connects rib 24, by the way of Vibration welding, welding rib 24 is melted,
Effectively existing upper slice inner side can be welding together with fixed station 23 sidepiece.
Outside in view of the position relationship between pressure stabilizing cavity and ring flange 22, actually pressure stabilizing cavity
Fixed station 23 position relationship on sidewall bodies and ring flange 22, it is desirable to by existing upper slice 20 have
Effect be fixed on fixed station 23 sidepiece, that existing upper slice outside 20 wall body to existing upper slice 20
Thickness between the wall body of inner side will be considerably beyond the thickness of existing bottom sheet 21.During injection mo(u)lding,
Local thickness is the thickest, cooldown rate can be caused to differ greatly, be easily caused injection-molded plaques body deformability relatively
Greatly, it is difficult to produce qualified product.It is thus desirable to cut down existing upper slice 20 thickness.
Assume from existing upper slice cut down inside 20 existing upper slice 20 thickness, may result in like that
Air inlet does not meets design requirement.Because the size of pressure stabilizing cavity, the size of air inlet is all root
Accurately calculating according to the performance requirement of electromotor, the size of air inlet is to change
's.If but cut down existing upper slice thickness inside 20 and will increase the internal diameter of air inlet,
Product is caused not meet design requirement.
Assume from existing upper slice cut down outside 20 existing upper slice 20 thickness, due to existing upper slice
20 ends need and fixed station 23 sidepiece is welded to connect, the external diameter of fixed station 23 and pressure stabilizing cavity
External diameter suitable.Cut down existing upper slice thickness outside 20 can only existing upper slice 20 outside
Dig out a groove (upper slice end can not be moved, and needs to coordinate) with the fixed station 23 on ring flange 22,
Such structure will make mould be stuck in manifold (as it is shown on figure 3, mould is from hanging down when depanning
Straight drawing inward direction is to vertical drawing outwardly direction out), it is impossible to depanning.
As can be seen here, air inlet is divided into upper and lower two panels not can solve upper slice lamellar body
The thickest problem.
