Abstract
A cooling water pump of an automobile engine comprises a water pump body, a shaft-connecting-shaft bearing and an impeller, wherein the shaft-connecting-shaft bearing penetrates through the water pump body; water seal is pressed between the shaft-connecting-shaft bearing and the water pump body; the impeller is pressed at the front end of the shaft-connecting-shaft bearing and a flange is pressed at the rear end of the bearing; a water storage cavity is arranged in the water pump body; and a blocking cover is arranged at the opening part of the water storage cavity at the rear end of the water pump body. The cooling water pump is characterized in that the blocking cover is used for sealing the opening of the water storage cavity as the size of the cover is mated with that of the water storage cavity, and is provided with a through hole for leakage. In the cooling water pump, the structures of the existing water pump body and the existing blocking cover are improved, a leakage gap at the water storage cavity of the water pump body is eliminated, and the small through hole is machined on the blocking cover to replace the leakage gap, so that a mould is convenient to manufacture and is easy to demould, the service life of the mould is prolonged and the mould is more convenient to maintain; and simultaneously, the integral weight of the water pump is reduced, the production efficiency is improved in the premise of not influencing the whole performances of a product, and the cost is reduced, so that the cooling water pump meets the development trend of light vehicles.
Description
Technical field
The utility model belongs to the pump technology field, relates to a kind of automobile engine cooling water pump, the cooling waterpump in especially a kind of being applied to, in the light automobile.
Background technique
Traditional automobile engine cooling water pump does not design water storage cavity, erroneous judgement to the inefficacy of leaking appears easily, present newly-designed water pump has generally increased water storage cavity, structure is with reference to figure 4, shown in 5, specifically comprise water pump body 3, impeller 1, shaft connecting bearing 4, water seal 2, blanking cover 6, flange 5, in water pump body 3, be provided with water storage cavity 31, opening at water storage cavity 31 is provided with leakage breach 32, assembly relation is: shaft connecting bearing 4 is press-fitted in the water pump body 3, blanking cover 6 is press-fitted in the water pump body 3, the axle that water seal 2 is press-fitted into shaft connecting bearing 4 go up and water pump body 3 in, flange 5 is press-fitted on the axle of shaft connecting bearing 4 rear ends, impeller 1 be press-fitted into shaft connecting bearing 4 front ends spool on.
Wherein, the place has reserved the leakage breach at the water pump body water storage cavity, and this breach is all smaller, increased the difficulty that mould is made, in process of manufacture, product is difficult for the demoulding in addition, cause mould to draw core easily and break in product, influence manufacturing efficiency, increase the Mold repair cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mould difficulty low, the easily manufactured and easy automobile engine cooling water pump of the demoulding at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of automobile engine cooling water pump, comprise water pump body, shaft connecting bearing and impeller, shaft connecting bearing passes water pump body, between shaft connecting bearing and water pump body, be pressed into water seal, the front end of shaft connecting bearing is pressed with impeller, the rear end is pressed with flange, be provided with water storage cavity in the water pump body, opening at the rear end of water pump body water storage cavity is provided with blanking cover, it is characterized in that: the opening of described blanking cover and water storage cavity is the size fitted seal just in time, offers a through hole that is used to leak on the described blanking cover.
As improvement, the cross section of described blanking cover is circular, and the opening of the rear end water storage cavity of described water pump body is corresponding circular open, and described blanking cover is embedded at sealing and fixing in the circular open.
At last, described through hole is located at the central position of blanking cover.
Compared with prior art, advantage of the present utility model is: the structure to water pump body and blanking cover is improved, water storage cavity place at water pump body has cancelled the leakage breach, little through hole of processing replaces leaking breach on blanking cover simultaneously, make mould easily manufactured, the demoulding is easy, greatly reduce the mould manufacture difficulty, promoted die life, and be more convenient for safeguarding; Make the water pump overall weight decrease simultaneously, improved manufacturing efficiency not influencing under the overall performance prerequisite of product, saved cost, meet the light-duty vehicle development trend.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a side view of the present utility model;
Fig. 3 is the structural representation of blanking cover;
Fig. 4 is the prior art constructions schematic representation;
Fig. 5 is the side view of prior art.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, a kind of automobile engine cooling water pump, comprise belt pulley, water pump body 3, shaft connecting bearing 4, water seal 2, flange 5 and impeller 1, shaft connecting bearing 4 passes water pump body 3, between shaft connecting bearing 4 and water pump body 3, be pressed into water seal 2, impeller 1 is arranged at the front end of shaft connecting bearing 4, flange 5 press-fits in the rear end of shaft connecting bearing 4, be provided with water storage cavity 31 in the water pump body 3, opening at the rear end of water pump body 3 water storage cavity 31 is pressed with blanking cover 6 (as Fig. 3), the cross section of described blanking cover 6 is circular, the opening of the rear end water storage cavity 31 of described water pump body 3 is corresponding circular open, blanking cover 6 is embedded in the circular open with water storage cavity 31 just in time size fitted seal, and the central position of described blanking cover 6 offers a through hole that is used to leak 61.
Make like this and should forward on the blanking cover 6, utilize the through hole 61 on the blanking cover 6 to replace leaking breach, make that the manufacturing of mould is simple and direct by the leakage breach that water pump body 3 is finished, easily manufactured, the demoulding is easy, has improved manufacturing efficiency simultaneously, has saved cost.
