Description
Technical field
The utility model relates to electronic water pump for automobile production technical fields, and in particular to for producing electronic water pump modeling magnetic leaf
Two template dies of wheel.
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.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of for producing two template dies of electronic water pump modeling magnetic impeller,
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 utility model provides two template dies for producing electronic water pump modeling magnetic impeller, 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 leaf in upper mold
Top vane wheel hub die cavity is taken turns, the impeller cylinder mould chamber of water pump vane lower part, die cavity inside upper mold and lower die splice grafting are equipped in lower die
Water pump vane shape shape chamber is formed, is equipped with vertical injection molding cavity in the upper mold, injection molding cavity bottom is located at wheel hub cavity center.
It is that injection molding cavity is conical desk shape that described the utility model, which is further improved scheme, and diameter is gradually increased from top to bottom.
Water pump vane can integrally take out with useless stick when because of upper and lower mould die sinking, then fracture that remove useless stick more easy to operate, click through glue and open unlike two
Two pulling hooks are needed when mould, when product is stained with mould, need to be shut down and be removed stagnant mould cast gate, the implementation of the utility model improves product
Performance also improves and produces efficiency.
Described the utility model is further improved scheme, and the blade wheel hub die cavity is using vertebra platform shape as center chamber circumferential direction
Interval, which is enclosed, sets blade cavity, and the impeller cylinder mould chamber is cylindric die cavity.
Realize that the center single-point of electronic water pump modeling magnetic impeller is molded production technology using two template dies:
Above-mentioned two template die is assembled, injection fluid moulds magnetic from injection molding cavity top, and fluid moulds magnetic from water pump vane shape shape chamber
Top center fills die cavity by 360 ° of fillings downwards of surrounding, and upper mold lower die is separated after solidification, takes out injection molding product, fracture removal
Center injection molding cavity gives up stick to get water pump modeling magnetic impeller.
The utility model compared with prior art, has following obvious advantage:
One, the utility model is realized for producing electronic water pump impeller from its top impeller central point single-point into glue, moulds magnetic
Material is filled downwards along cavity by 360 ° of surrounding from top, and the electronic water pump modeling magnetic impeller of injection molding does not have weld mark, product
Magnetic property gets a promotion.
Two, waste material is only a truncated cone shape bar in the utility model note cavity mold, is the part in former three template die upper molds, weight
It is original 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 of every production
Impeller of pump can save nearly 1.60 yuan, and material cost is greatly saved.
