Description
Technical field
The present invention relates to electronic water pump for automobile production technical fields, and in particular to for producing electronic water pump modeling magnetic impeller
Two template dies and the center single-point Shooting Technique that electronic water pump modeling magnetic impeller is realized using two template dies.
Background technique
Electronic water pump for automobile impeller is integrally formed by modeling magnetic material injection, is clicked through glue using three template dies two at present and is molded work
Skill, as shown in Fig. 2, three template dies include upper mold, middle mould and lower die, middle mould bottom is equipped with water pump vane top vane wheel hub die cavity,
Lower die is equipped with the impeller tubular die cavity of water pump vane lower part, and die cavity forms water pump vane shape shape chamber inside middle mould and lower die splice grafting,
Injection molding cavity under " n " type is equipped in middle mould, the bottom of the two vertical footing injection molding cavities in left and right is located at wheel hub cavity or so edge, on
Vertical taper injection molding cavity is equipped in mould.When production, flow-like modeling magnetic material enters from upper injection molding cavity top, is then tapped off to water
The left and right sides of impeller of pump shape shape chamber, which is filled downwards, fills die cavity, therefore two click through glue injection molding liquid modeling magnetic in impeller cylinder mould chamber
In converge from two sides, just will form weld mark after solidification, weld mark can generate certain negatively influencing to the performance of product.When demoulding
Since injection molding cavity is fork type, it is necessary to which mould and lower die, injection molding cavity material mouth and water pump vane injection molding product are necessary in first separating
First break, thus the tie point section of the two cannot be too big, therefore being molded injection pressure must be sufficiently large, product appearance could nothing
Defect, not only injection efficiency is low, but also is also uncontrollable to product quality.It separates upper mold and middle mould takes out in injection molding cavity and gives up
Material, waste material generally weigh 19g or so, consider that waste material melt back recycling is affected to properties of product, largely make waste treatment,
And magnetic raw material about 130,000/ton is moulded, value is more expensive, and waste material also becomes important a part of finished product cost of material in injection molding cavity.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of center single-point injecting glues of electronic water pump modeling magnetic impeller to produce work
Skill, using two template dies, from water pump vane die cavity top center point single-point into glue, fluid modeling magnetic material is from top along cavity by surrounding
360 ° are filled downwards, and the electronic water pump impeller of injection molding does not have weld mark, and product magnetic property gets a promotion.Four points are reduced simultaneously
One of more than injection molding waste generate, save expensive raw material, reduce production cost.
The present invention is provided to produce two template dies of electronic water pump modeling magnetic impeller, it is achieved through the following technical solutions:
For producing two template dies of electronic water pump modeling magnetic impeller, including upper die and lower die, bottom is equipped with water pump vane top in upper mold
Portion's blade wheel hub die cavity, the impeller cylinder mould chamber of water pump vane lower part is equipped in lower die, and upper mold and lower die splice grafting inside die cavity are formed
Water pump vane shape shape chamber is equipped with vertical injection molding cavity in the upper mold, and injection molding cavity bottom is located at wheel hub cavity center.
The further improvement scheme of the present invention is that injection molding cavity is conical desk shape, and diameter is gradually increased from top to bottom.Because upper
Water pump vane can integrally take out with useless stick when lower die is opened, then fracture that remove useless stick more easy to operate, unlike when two, which click through glue, is opened
Two pulling hooks are needed, when product is stained with mould, need to shut down and remove stagnant mould cast gate, implementation of the invention improves properties of product,
Raising produces efficiency.
The further improvement scheme of the present invention is that the blade wheel hub die cavity is circumferentially-spaced using vertebra platform shape as center chamber
It encloses and sets blade cavity, the impeller cylinder mould chamber is cylindric die cavity.
The present invention provides the skills for the center single-point injection molding production technology that electronic water pump modeling magnetic impeller is realized using two template dies
Art scheme:
The center single-point that electronic water pump moulds magnetic impeller is molded production technology, assembles any one of claims 1 to 3 two plate
Mould, from injection molding cavity top, injection fluid moulds magnetic, and it is downward by 360 ° of surrounding from the top center of water pump vane shape shape chamber that fluid moulds magnetic
Filling fills die cavity, and upper mold lower die is separated after solidification, takes out injection molding product, fractures and removes the useless stick of center injection molding cavity to get water
Pump modeling magnetic impeller.
Compared with prior art, the present invention having following obvious advantage:
One, the present invention is realized for producing electronic water pump impeller from its top impeller central point single-point into glue, moulds magnetic material from top
Portion is along cavity by 360 ° of fillings downwards of surrounding, and the electronic water pump modeling magnetic impeller of injection molding does not have weld mark, and product magnetic property obtains
To promotion.
Two, waste material is only a truncated cone shape bar in present invention note cavity mold, is the part in former three template die upper molds, and weight is former
Carry out waste material one third less than only 5-6g, by modeling about 0.13 yuan/g of magnetic material price at present, one electronic water pump leaf of every production
Wheel can save nearly 1.60 yuan, and material cost is greatly saved.
