Abstract
The utility model relates to a diesel engine technical field, concretely relates to diesel engine intake pipe convenient to loose core, this intake pipe should be able to easily realize the drawing of patterns, guarantees product quality, still should have simple structure, make convenient characteristics. For realizing above mesh, the utility model discloses a technical scheme below: a diesel engine intake pipe convenient to loose core, includes the intake pipe main part, has seted up a plurality of connecting hole in this intake pipe main part, every connecting hole has to the intake pipe main part outside bellied semi -cylindrical surface shape pore wall, its characterized in that: the middle part system of semi -cylindrical surface shape pore wall has a breach, the bottom of this breach and the outer wall parallel and level of intake pipe main part. The strengthening rib has been made respectively at the both sides border of breach, the strengthening rib extends along the axial of connecting hole.
Description
Technical field
This utility model relates to diesel engine technologies field, is specifically related to a kind of Diesel engine air inlet pipe be easy to and loose core.
Background technology
Air inlet pipe is the vitals of electromotor, and air enters (mainly four-valve engine) in electromotor by air inlet pipe, provides oxygen for the burning of in-engine fuel oil.In existing engine air inlet tube, air inlet pipe main body offering multiple connecting hole, air inlet pipe main body is fixed on electromotor by long bolt after connecting hole.Due to the aperture of connecting hole less (usual 5 to 8 millimeters) and length longer (general more than 10 centimetres), difficulty of loosing core in casting process, product quality is impacted, wait to solve.
Utility model content
The purpose of this utility model is to overcome the deficiency in above-mentioned background technology, it is provided that a kind of Diesel engine air inlet pipe being easy to loose core, and this air inlet pipe should be able to easily realize the demoulding, it is ensured that product quality, also should have simple in construction, easily manufactured feature.
For realizing object above, this utility model have employed following technical scheme:
A kind of Diesel engine air inlet pipe being easy to loose core, including air inlet pipe main body, this air inlet pipe main body offers several connecting holes, each connecting hole has semi-cylindrical shape hole wall protruding outside air inlet pipe main body, it is characterized in that: the middle part of semi-cylindrical shape hole wall is shaped with a breach, the bottom of this breach is concordant with the outer wall of air inlet pipe main body.
As preferably, the dual-side of described breach along being formed respectively with reinforcement, axially extending along connecting hole of described reinforcement.
As preferably, the length of described breach is 4-7cm.
As preferably, described air inlet pipe main body is aluminium casting.
The beneficial effects of the utility model: the wall portion of connecting hole is excised by this utility model, form a breach, it is possible to effectively reduce the frictional force of core rod and hole wall when loosing core so that loose core conveniently；And reinforcement is set in the both sides of breach and is conducive to keeping intensity, overall structure is simple, easily manufactured, less costly.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 of the present utility model looks up structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but this utility model is not limited to following example.
As shown in Figure 1, 2, a kind of Diesel engine air inlet pipe being easy to loose core described in the utility model, including air inlet pipe main body 1, this air inlet pipe main body offers several connecting holes 2, each connecting hole has semi-cylindrical shape hole wall 3 protruding outside air inlet pipe main body, and said structure is similar with existing air inlet pipe.
Of the present utility model the improvement is that, it is shaped with a breach 4 at the middle part of semi-cylindrical shape hole wall, the bottom of this breach is concordant with the outer wall of air inlet pipe main body, namely (now there is the groove 6 of a semi-cylindrical shape, i.e. the half of connecting hole in breach) till switching to down the outer wall of air inlet pipe main body.The dual-side of described breach along being formed respectively with reinforcement 5, axially extending along connecting hole of described reinforcement, and extend to the two ends of breach.The length of described breach is 4-7cm.Described air inlet pipe main body is that aluminium casting, reinforcement and breach are one-body molded with connecting hole when casting.
Finally it should be noted that obviously, this utility model is not limited to above example, it is also possible to have many variations.All deformation that those of ordinary skill in the art can directly derive from this utility model disclosure or associate, are all considered as protection domain of the present utility model.
