Abstract
The utility model discloses a mould used for producing an impeller. The mould used for producing the impeller comprises an upper punch (1), a female mould (2), a first lower punch (3-1), a second lower punch (3-2) and a core bar (4). The upper punch (1), the female mould (2), the first lower punch (3-1), the second lower punch (3-2) and the core bar (4) are combined to form a mold cavity. The mould used for producing the impeller is characterized in that the female mould (2) is arranged to be in the shape of a female mould step, a female mould cavity is formed inside the female mould (2), the core bar (4) is axially connected to the first lower punch (3-1) and the second lower punch (3-2), and the upper punch (1) is matched with the first lower punch (3-1) and the second lower punch (3-2). The requirement that high materials are adopted to machine the water pump impeller into a special shape is realized though precise casting angle adjustment and reasonable mould shape design, the strength of the impeller is enhanced, the strength requirement of a cold stamping mould is met, service life is prolonged and the environment is protected.
Description
Technical field
The utility model relates to a kind of auto parts machinery field, relates in particular to a kind of mould for the production of this impeller.
Background technology
Auto pump plays vital effect to the cooling water circulation running of whole car engine inside, at present, Water-pump impeller of automobile adopts ironcasting, sheet stamping member and plastic material pressure injection to make mostly, the water pump that above-mentioned material is made in use often meets with corrosion, service life is short, foundry goods or working of plastics easily cause environmental pollution aborning, and stamping parts is because shape is high to the requirement of strength of Cold pressing die; In addition, the water pump vane dynamic balance performance that adopts ironcasting, sheet stamping member and plastic material pressure injection to make is difficult for accomplishing the standard-required of 40g/cm.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of mould of producing this impeller.
In order to solve the problems of the technologies described above, the utility model provides a kind of mould for the production of impeller, it comprises upper punch, former, the first undershoot, the second undershoot and plug, upper punch, former, the first undershoot, the second undershoot and plug are combined to form die cavity, described former is set to the former step, form negative impression in the former, described mandrel axis is to being connected in the first undershoot and the second undershoot, and described upper punch matches with the first undershoot and the second undershoot.
Described the first undershoot and rush to for second time and be provided with undershoot backing plate and undershoot cover plate.
Adopt said structure, the beneficial effects of the utility model are:
Described mould adopts the mode of whole pressure injection to produce impeller; accurate adjustment pressure injection angle adds rational designing mould shape; realized selecting higher material to be processed into the requirement of water pump vane special shape; above-mentioned strictly accurately control to impeller angle; cooling water pump to whole automobile reaches the cooling effect, strengthens impeller intensity, reaches the requirement of strength of Cold pressing die; increase the service life protection of the environment.
, save time so that the disposable injection-compression molding of impeller can be produced in enormous quantities by mould, reduce production costs.
Description of drawings
Fig. 1 is the assembly drawing of production impeller mold of the present utility model.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of mould for the production of impeller of the present utility model, it comprises upper punch 1, former 2, the first undershoot 3-1, the second undershoot 3-2 and plug 4, upper punch 1, former 2, the first undershoot 3-1, the second undershoot 3-2 and plug 4 are combined to form die cavity, described former 2 is set to the former step, former 2 interior formation negative impression, described plug 4 axially is connected in the first undershoot 3-1 and the second undershoot 3-2, and described upper punch 1 matches with the first undershoot 3-1 and the second undershoot 3-2.
The utility model by the flow process of Mold Making water pump vane is: after impeller mold installs; the debugging press; female die step; when upper punch 1 is unkitted, press run to 180 ° of seats in the plane; measure former 2 to first undershoot 3-1; the height of the second undershoot 3-2; whether reach casting die height 3-5mm; filling former 2 and the first undershoot 3-1; the second undershoot 3-2; input press data; open the press motor; this moment, press was 270 ° of seats in the plane; press the both hands control button; former 2 fillings begin; simultaneously filling of the first undershoot 3-1 and the second undershoot 3-2; inhalation is adopted in the filling at the first undershoot 3-1 and the second undershoot 3-2 place; guarantee that eight lobe place filling powder amounts are identical; when press runs to 0 °; former 2 and the first undershoot 3-1; the second undershoot 3-2 filling is complete, and the feed box powder feeding is when press runs to 15 °; feed box is return the feeding seat in the plane; upper punch 1 pressing action begins simultaneously, and upper punch 1 runs in the negative impression, and the press angles of display is between 122-130 °; former 2 floats downwards; upper punch 1 continues to move downward, and when press operation angle during at 150 °, former 2 floats and puts in place; during 165 ° of upper punch 1 motions; the air pressure downward air pressure protection that resets is opened, and upper punch 1 continues to press down until 180 °, and impeller is shaped; from 190 °; demoulding action beginning, the negative template beginning of leaving behind is when press runs to 230 °; large cylindrical depanning; former demoulding this moment push rod pushes up next plate, begins to take off the first undershoot 3-1 and the second undershoot 3-2 shaped portion, and press runs to 250 °; the casting die demoulding is complete; the top shoe backhaul, upper punch 1 also continues to push down casting die, and press runs to 260 ° of upper punch backhauls; press runs to the seat in the plane, and the compacting action is finished.
