Abstract
The invention relates to a covering hood of diesel engine cylinder, which comprises a cover body prepared from woolen cloth material by onestep injection molding via a mold, wherein the bottom margin of the cover body is composed of four circular arcs and extending edges thereof, a fixed hole is provided at the interjunction site of the left two circular arcs, a fixed hole is provided at the interjunction site of the extending edges of the right two circular arcs, and a sag is respectively formed at the interjunction site of extending edges of the corresponding two circular arcs at the front and back sides; a steel jacket integrally injection molded with the cover body is respectively provided inside the fixed holes; an external strengthening rib is respectively provided at the outer side wall of the lower part of the cover body and at the outer side walls of the sag portions at the front and back sides, and an internal strengthening rib is respectively provided at the inner side walls of the sag portions at the front and back sides. The cover body in the invention is prepared from woolen cloth material by injection molding so as to reduce the manufacturing cost and noise; and the steel jacket integrally injection molded with the cover body can prevent local creepage of the cover body.
Description
Technical field
The present invention relates to a kind of diesel engine part, specifically a kind of diesel engine cylinder head cover.
Background technique
Diesel engine cylinder head cover is a kind of accessory of diesel engine, is widely used.Traditional diesel engine cylinder head cover all is to adopt aluminum alloy material injection molded, and its manufacture cost height, weight are greatly, the noise of generation is big when working.
Summary of the invention
The purpose of this invention is to provide the diesel engine cylinder head cover that a kind of cost is low, noise is little.
For achieving the above object, the present invention is by the following technical solutions:
Diesel engine cylinder head cover of the present invention, it comprises adopts Buddhist nun's down material through the disposable injection molded cover body of mould, the base of cover body is made up of four circular arcs and prolongation limit thereof, the intersection of two circular arcs in left side is provided with left fixed hole, the intersection that two circular arcs in right side prolong the limit is provided with right fixed hole, and the intersection that two circular arcs of both sides, front and back correspondence prolong the limit all forms depression; Be respectively equipped with the steel bushing that becomes one with the cover body injection moulding in left side fixed hole, the right fixed hole; The outer side wall at depression position, on the bottom outer side wall of cover body and the both sides, front and back of cover body is provided with outer stiffening rib, and the madial wall at the depression position, both sides, front and back of cover body is provided with interior stiffening rib.
Above-mentioned outer stiffening rib and interior stiffening rib are the strip projected parts that is connected as a single entity with cover body.
The sectional shape of above-mentioned outer stiffening rib and interior stiffening rib is rectangle or semicircle.
Described cover body is to be mother metal with enhancing property Buddhist nun suede, has wherein added antiageing agent, creep resistant agent and oil resistant, corrosion resistant, exotic material.
Cover body of the present invention adopts Buddhist nun's down material injection molded, compares with traditional diesel engine cylinder head cover, and manufacture cost reduces by 20%, can reduce noise; On cover body, be provided with the steel bushing that injection moulding with it becomes one, can prevent that it from local creep taking place.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
A kind of diesel engine cylinder head cover, as shown in Figure 1 and Figure 2, it comprises adopts Buddhist nun's down material through the disposable injection molded cover body 1 of mould, the base of cover body 1 is made up of four circular arcs and prolongation limit thereof, the intersection of two circular arcs in left side is provided with left fixed hole 11, the intersection that two circular arcs in right side prolong the limit is provided with right fixed hole 12, and the intersection that two circular arcs of both sides, front and back correspondence prolong the limit all forms depression; Be respectively equipped with the steel bushing 41,42 that becomes one with cover body 1 injection moulding in left side fixed hole 11 and the right fixed hole 12, steel bushing can prevent that cover body from local creep taking place; The outer side wall at depression position, on the bottom outer side wall of the cover body 1 and both sides, front and back of cover body 1 is provided with outer stiffening rib 2, stiffening rib 3 in the madial wall at the depression position, both sides, front and back of cover body 1 is provided with, and outer stiffening rib 2 and interior stiffening rib 3 can play the effect of reinforcing cover body.Outer stiffening rib and interior stiffening rib are rectangle or the semicircle strip projected parts that is connected as a single entity with cover body.
In the present embodiment, cover body 1 is to be mother metal with enhancing property Buddhist nun suede, adds antiageing agent, creep resistant agent and oil resistant, corrosion resistant, exotic material, and is disposable injection molded through mould.Like this, cover body 1 has just had good ageing resistance, creep resistance and oil resistant, corrosion resistant, resistance to high temperature.
But the present invention's tie spacer 5 uses.Pad 5, as shown in Figure 3, its shape is corresponding with the shape on cover body 1 base, and pad 5 can strengthen the sealability of valve mechanism cover, prevents leakage of oil, and in addition, high temperature resistant, the anti-aging material of spraying can be alleviated the creep of valve mechanism cover on pad 5.
