Abstract
The utility model discloses a kind of die-cast rotor housings, including with the integrally formed support post of cylinder body, be provided with striated structure on the outer surface of the support post, the support post be it is cylindric, striated structure is knurling structure.Using the utility model die-cast rotor housing, the mechanical performance for improving engine cylinder body can be improved, solve the defect that column bottom generates stomata, improve production efficiency, save the cost improves quality.
Description
Technical field
The utility model relates to engine cylinder body technical fields, and in particular to a kind of die-cast rotor housing.
Background technique
Existing cylinder body support post design is higher, and cooling effect is bad, and bottom is caused stomata occur, reduces engine
The mechanical performance of cylinder body since support post is disposed adjacent with water jacket is also easy to that water jacket is caused to leak.
Utility model content
In view of this, raising engine cylinder body can be improved the purpose of this utility model is to provide a kind of die-cast rotor housing
Mechanical performance, solve column bottom generate stomata defect, improve production efficiency, save the cost, improve quality.
A kind of die-cast rotor housing of the utility model, including with the integrally formed support post of cylinder body, the support post it is outer
Striated structure is provided on surface.
Further, the support post is cylindric.
Further, the striated structure is knurling structure.
Further, water jacket is provided in the cylinder body, the water jacket is arranged around the inner cavity of cylinder body, the bottom of the water jacket
Extend to the cylinder body region where support post.
Further, the water jacket is the thin-walled water jacket that cylinder body top-slitting is formed.
Further, the support post is perpendicular to plane where water jacket.
Further, reinforcing rib is provided between the cylinder body and support post.
Further, blind hole is provided on the support post, the blind hole is from the top of support post along support post
Length direction extend.
Further, the cylinder body is made of aluminum alloy materials.
The utility model has the beneficial effects that can be improved using the utility model die-cast rotor housing and improve engine cylinder body
Mechanical performance solves the defect that column bottom generates stomata, improves production efficiency, and save the cost improves quality.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model cylinder body；
Fig. 2 is schematic cross-section of the Fig. 1 along A-A.
Specific embodiment
Fig. 1 is the structural schematic diagram of the utility model cylinder body, and Fig. 2 is schematic cross-section of the Fig. 1 along A-A.The utility model
A kind of die-cast rotor housing, including with the integrally formed support post 1 of cylinder body 2, be provided with striped on the outer surface of the support post 1
Structure.By the way that striated structure is arranged, the surface area for increasing support post 1 increases the cold of support post 1 after die cast
But effect solves the defect that column bottom generates stomata, improves production efficiency, and save the cost improves quality.
In the present embodiment, the support post 1 be it is cylindric, keep die cast more simple, same section, area is more
Greatly, while ensure that support stiffness, reduce the weight of cylinder body entirety.
In the present embodiment, the striated structure is knurling structure, and using the structure of knurling, processing is more convenient, is subtracted
Lack difficulty of processing, improves efficiency.
In the present embodiment, water jacket 3 is provided in the cylinder body 2, the water jacket 3 is arranged around the inner cavity of cylinder body 2, the water
The bottom of set 3 extends to the cylinder body region where support post 1, and support post 1 is arranged in the bottom position of water jacket 3, increases
The bottom structure rigidity of water jacket 3.
In the present embodiment, the water jacket 3 is the thin-walled water jacket that 2 top-slitting of cylinder body is formed, and the cylinder body 2 that this place is stated pushes up
Portion refers to the plane on engine where lower cylinder body cooperation, it will be understood that upper lower cylinder body is slotted, and common molding is complete
Thin-walled water jacket.
In the present embodiment, the support post 1 facilitates cylinder body pressure using such setting perpendicular to 3 place plane of water jacket
Type casting moulding.
In the present embodiment, it is provided with reinforcing rib 4 between the cylinder body 2 and support post 1, enhances the branch of support post 1
Support rigidity.
In the present embodiment, it is provided with blind hole 5 on institute's support post 1, the blind hole 5 is from the top edge of support post 1
The length direction of support post 1 extend, can quickly allow support post 1 cooling, cooling effect is more preferable.
In the present embodiment, the cylinder body 2 is made of aluminum alloy materials, for cylinder body 2 made of aluminum alloy materials, die casting
Simpler, the processing of striated structure is also simpler.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
