Abstract
The utility model discloses a hub die's lower mould, including the lower mould body, the lower mould body includes a plurality of juts and depressed part, and every jut lies in between two depressed parts, and one of the directional lower mould body edge of every depressed part is served all to seal up and is equipped with the cooling chamber, the inside circulation canal who communicates in the cooling chamber that is equipped with of depressed part, the cooling chamber cross sectional shape is trapezoidal, just the height that highly is less than the jut of cooling chamber. The utility model discloses a set up the cooling chamber in depressed part one end, make the wheel hub spoke more even for prior art with the thickness of rim junction to through circulation canal to cooling chamber injection cooling water or cold wind, make spoke and rim junction cooling rate obtain improving, too big crystalline grain can not appear, make the wheel hub performance of casting out get a promotion, have better intensity.
Description
Technical field
The utility model relates to technology of die manufacturing field, particularly relates to a kind of counterdie of hub mold.
Background technology
Wheel hub is as a part for automobile, it adopts die casting shaping mostly, existing wheel hub structure as shown in Figure 1, by die casting time, due to the vibrational power flow of upper and lower mould, the wall thickness at the spoke of wheel hub and wheel rim junction (in Fig. 1 A place) is relatively thick, therefore when casting, during the cooling of A place, cooling velocity is comparatively slow, easily causes casting loose, and easily leak gas and cause product rejection, percent defective is higher; And the longer crystal grain at A place that causes again is thicker cool time, cause its mechanical property poor, the performance of the whole wheel hub of final impact.Therefore, when carrying out wheel hub casting, how making A place cooling velocity get a promotion is one of problem that will solve at present.
Utility model content
The purpose of this utility model is the counterdie providing a kind of hub mold, the thickness of the spoke of the wheel hub casting out and wheel rim junction can be made more even, and improve the cooling velocity of this junction.
For reaching this object, the utility model is by the following technical solutions: a kind of counterdie of hub mold, comprise lower mould body, described lower mould body comprises some juts and depressed part, each protruding part is between two depressed parts, on one end of each depressed part sensing counterdie body edges, all sealing is provided with cooling chamber, and described depressed part inside is provided with the circulation canal being communicated in cooling chamber; Described cooling chamber cross sectional shape is trapezoidal, and the height of described cooling chamber is lower than the height of jut.
As preferably, described jut and depressed part circumference are distributed on lower mould body.
As preferably, described jut and depressed part are five, corresponding, and described cooling chamber is set to five.
As preferably, described cooling chamber is positioned at the center position that depressed part points to one end of counterdie body edges.
As preferably, described circulation canal entrance is arranged at below cooling chamber, and described circulation canal is in the tilted setting of depressed part.
The beneficial effects of the utility model: by arranging cooling chamber in depressed part one end, make the thickness of wheel hub spoke and wheel rim junction more even relative to prior art, and inject cooling water or cold wind by circulation canal to cooling chamber, spoke and wheel rim junction cooling velocity are improved, there will not be excessive crystal grain, the wheel hub performance cast out is got a promotion, there is good intensity.
By cooling chamber cross section is set to trapezium structure, cooling water or the wheel hub cooling of cold wind to casting that can make to enter cooling chamber are more abundant.

Fig. 2 is the structural representation of the utility model counterdie;
Fig. 3 is that the A-A of the utility model Fig. 2 is to schematic diagram.
In figure:
1, lower mould body; 2, cooling chamber; 3, circulation canal; 11, jut; 12, depressed part.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As Figure 2-3, the utility model provides a kind of counterdie of hub mold, comprise lower mould body 1, lower mould body 1 is provided with some juts 11 and depressed part 12, each jut 11 between two depressed parts 12, i.e. jut 11 and the spaced setting of depressed part 12, preferably, jut 11 in the present embodiment and depressed part 12 are five, make final casting wheel hub out have good intensity.
On the one end at each lower mould body 1 edge of depressed part 12 sensing, all sealing is provided with cooling chamber 2, concrete, this cooling chamber 2 is arranged on the junction of spoke and wheel rim when wheel hub is cast, and then make this cooling chamber 2 one aspect reduce the thickness of spoke and wheel rim junction due to the setting of its structure, make the thickness of spoke and wheel rim junction more even; On the other hand, by injecting cooling water or cold wind to cooling chamber 2, when can accelerate to cast, the cooling of spoke and wheel rim junction, makes the cooling velocity of this junction be improved, and avoids occurring excessive crystal grain, affects the mechanical property of this junction.In the present embodiment, cooling chamber 2 is set to five.
The circulation canal 3 being communicated in cooling chamber 2 is provided with, for injecting cooling water or cold wind to cooling chamber 2 Inner eycle in depressed part 12 inside.
In the present embodiment, the cross sectional shape of cooling chamber 2 is trapezoidal, why is set to trapezium structure, is the contact area in order to improve cooling chamber 2 and the wheel hub of casting, so make to enter the cooling water of cooling chamber 2 or the wheel hub cooling of cold wind to casting more abundant.In the present embodiment, the height of cooling chamber 2 is lower than the height of jut 11.
In the present embodiment, jut 11 and depressed part 12 all circumference are distributed on lower mould body 1, i.e. the arrangement in five-pointed star, improves the intensity of casting wheel hub out.
Preferably, cooling chamber 2 is positioned at the center position that depressed part 12 points to the one end at lower mould body 1 edge, makes the thickness of spoke and the wheel rim junction cast more even.
The entrance of circulation canal 3 is arranged at below cooling chamber 2, and circulation canal 3 is in the tilted setting of depressed part 12, avoids and interferes with other cooling ducts.And entrance is arranged on below cooling chamber 2, can not impact wheel hub structure when also can ensure casting.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
