Description

Casting device
Technical field
The casting of cast member is obtained by being formed by type chamber when stent and But moving die molding the present invention relates to a kind of Device.
Background technique
By the melt (molten metal) of the metals such as the intracavitary filling aluminum of type in casting device, and cooled and solidified and Obtain cast member.Here, the intracavitary air of type can be involved in melt sometimes when melt is filled in type chamber.If occurring in this way The case where, then gas defects can be formed in cast member.Therefore, the quality of cast member is caused to decline.
In order to avoid such case, such as documented by Japanese invention patent Publication Japanese Laid-Open Patent Publication 4-157055 Like that, it in the product department's (a part of type chamber) for forming product, is connected at the final filling position finally filled by melt There is a plurality of overflow runner for making smelt overflow, moreover, being provided with the air that keeps type intracavitary to atmosphere in the downstream side of overflow runner The cooling exhaust portion (gas discharge portion) of discharge.In this case, the intracavitary air of type later, passes through cooling by melt extrusion Exhaust portion is disposed in atmosphere.
In this casting device, the melt for needing that institute's overflow is avoided to go out is discharged from cooling exhaust portion.Go out from the viewpoint Hair set in cooling exhaust portion as documented in Japanese invention patent Publication Japanese Laid-Open Patent Publication 4-157055 Set the design of cooling structure.This is because keeping the melt for reaching cooling exhaust portion rapid by cooling structure in this case Ground solidification.
In addition, setting has to a certain degree as documented in Japanese Utility Model Registration Section bulletin the 3077039th Multiple overflow parts of capacity are also effective.This is because initially enter in mold in this case and be involved in the intracavitary air of type and The melt of temperature decline is lodged in overflow part.
Summary of the invention
However, if cooling knot is arranged as documented in Japanese invention patent Publication Japanese Laid-Open Patent Publication 4-157055 Structure, or increase as documented in Japanese Utility Model Registration Section bulletin the 3077039th capacity or the growth of overflow part The path-length of cooling exhaust portion is then not easy to realize miniaturization, the lightweight of mold.That is, being cast involved in the prior art It makes in device, this problem of cost needed for making it difficult to reduce mold is significantly changed.
It is a primary object of the present invention to provide a kind of solidification by that can promote melt at the downstream of overflow part Realize the casting device of the miniaturization of cooling exhaust portion.
Another object of the present invention is to provide one kind can make mold small, lightweight and reduce needed for mold The casting device of cost.
According to an embodiment of the present invention, a kind of casting device is provided, have the stent that is positioned and fixed and The But moving die moved on close to or far away from the direction of the stent, when being molded by the stent and described movable Mould shape forming cavity, wherein it is formed with gas discharge portion, overflow part and melt outlet,
One end of the gas discharge portion is connected to the type chamber, and the other end is opened wide to atmosphere;
The overflow part enters between the gas discharge portion and the type chamber for the melt gone out from the type chamber overflow;
The melt outlet from the type chamber towards the overflow part,
The overflow part is upwardly extended in the side orthogonal with the joint surface of the stent and the But moving die.
The melt gone out from type chamber overflow enters melt filling part.Here, melt filling part with stent and But moving die The orthogonal side in joint surface upwardly extend.Therefore, the melt of entrance is detained and is filled.That is, in the present invention, it is molten by being arranged Body filling part, it is ensured that the space of the melt gone out from type chamber overflow can be captured.
After this, thus it is speculated that melt is flowed towards gas discharge portion.That is, in the present invention, melt can be made in overflow part Middle delay longer time.Moreover, therefore the flowing velocity of the melt in overflow part declines, and make temperature relatively quickly Decline.Therefore, it even if melt reaches gas discharge portion, can also make that its flowing velocity is small and temperature is low, and measure few.Therefore, When melt reaches in gas discharge portion, which rapidly solidifies.
Therefore, it can be realized the miniaturization of gas discharge portion.Thus, due to can be realized the miniaturization and light weight of mold Change, as a result, it is possible to costs needed for reducing mold.
In addition, making molten near melt outlet if melt filling part is set near the melt outlet away from release chamber Body insulation to a certain extent.Therefore, it is able to maintain that so-called riser effect.
It is preferred that are as follows: melt filling part is arranged at stent and But moving die, and the melt filling part of stent side respectively Position with the melt filling part of But moving die side is asymmetric position.In this configuration, melt can be made to first flow into either one Then melt filling part flows into the melt filling part of a remaining side.That is, increasing the travel path of melt, it is stranded in overflow part The interior residence time further increases.Therefore, because being easy to decline temperature further, therefore melt can be made to reach gas row Melt when putting in portion further rapidly solidifies.
Additionally, it is preferred that are as follows: the melt outlet from type chamber towards overflow part is formed on joint surface, and is gone out relative to melt The position that mouth is deviated to the direction parallel with joint surface forms the communication path of connection overflow part and gas discharge portion, moreover, edge Joint surface formed gas discharge portion.
In this configuration, make its traveling while changing the flow direction of melt.Therefore, flowing velocity declines, So as to prevent melt from overflowing from mold, i.e., so-called flash.Moreover, in this case, melt is not easy from overflow part to even Path flowing.In other words, it is easy to that melt is made to be stranded in melt filling part.Therefore, melt is made to be difficult to reach communication path, gas Discharge portion, to effectively further prevent flash.
Can also be in overflow part, in the upstream side of melt filling part, the melt gone out from type chamber overflow is temporarily accumulated in setting Melt reservoir.In this case, further increase the capacity of overflow part by melt reservoir.Moreover, because making to melt Body is further stranded in overflow part for a long time, therefore, it is difficult to make melt reach communication path, gas discharge portion, even if reaching Gas discharge portion also solidifies as described above and rapidly.
In such a case it is possible to which so that melt outlet is set as width becomes narrow with from type chamber towards overflow part.According to This, spreads melt immediately after melt enters overflow part.Therefore, because melt is made to be difficult to straight ahead, therefore it is easy to make Melt flows into melt filling part.
It is preferred that are as follows: make melt outlet width it is narrow in the case where, with from type chamber direction on the melt outlet The mode of overflow part expansion is provided with gradient.By the gradient, though make melt outlet width it is narrow in the case where, also can Enough keep the constant cross-sectional area of melt outlet.Therefore, keep exhaust velocity constant.
According to the present invention, it constitutes are as follows: overflow part is between type chamber and gas discharge portion, for what is gone out from the type chamber overflow Melt enters, and includes the melt filling upwardly extended in the side orthogonal with the joint surface of stent and But moving die in overflow part Portion.
Melt filling part is functioned as the space for capturing entered melt.Therefore, melt is detained in overflow part Longer time.During this period, flowing velocity reduces and temperature declines.Therefore, the flowing of the melt of gas discharge portion is reached Speed is small and temperature is low.Moreover, amount is few.Therefore, the melt for reaching gas discharge portion can be made rapidly to solidify.
Therefore, because can be realized the miniaturization of gas discharge portion, therefore it can be realized the miniaturization and lightweight of mold. As a result, it is possible to costs needed for reducing mold.

Specific embodiment
In the following, enumerating preferred embodiment, casting device according to the present invention is described in detail with reference to the attached drawings.
Fig. 1 be constitute present embodiment involved in casting device But moving die 10 whole general principal view, Fig. 2 be into The major part approximate vertical view of But moving die 10 and stent 12 when row molding.Stent 12 is positioned and fixed, on the other hand, But moving die 10 is under the action of displacement mechanism (not shown) (for example, hydraulic cylinder), in the direction close to or far away from stent 12 Upper movement.Since this structure is known features, description is omitted.
Type chamber forming portion (not shown) there are two being formed in stent 12, and there are two types for formation on But moving die 10 Chamber forming portion 14a, 14b.When being molded, the type chamber forming portion of 12 side of stent and the type chamber forming portion of 10 side of But moving die 14a, 14b are overlapped, and form two type chambers 16 shown in Fig. 2 accordingly.In addition, the terminal part of type chamber 16 is only shown in the Fig. 2, In other words, the most downstream side of the flow direction of melt L is only shown.In this case, as shown in figure 4, the formation of type chamber 16 can obtain To the shape of side shell 18a, 18b of engine for motor bicycle.That is, once-cast can be passed through according to casting device Obtain two cast members.
Two type chambers 16 are connected to via runner 19 with cast gate 20.That is, the melt L imported from cast gate 20 is divided by runner 19 It is assigned to type chamber 16.Therefore, side shell 18a, 18b are by the melt L that cools and solidifies in cast gate 20 and runner 19 (hereinafter, note For " craftsmanship position ", its appended drawing reference is set as 22) being connected.
As shown in Fig. 2, a part of stent 12 is directed to 10 type chamber outstanding protrusion 24 of But moving die, and But moving die 10 position corresponding with protrusion 24 with type chamber is the type chamber recess portion 26 of recess.The terminal part of type chamber 16 is formed in type chamber with convex The joint surface in portion 24 and type chamber recess portion 26.On the other hand, it is formed in stent 12 and the joint surface of the flat part of But moving die 10 There is cooling exhaust portion 30 (gas discharge portion).Cooling exhaust portion 30 is formed by exhaust paddy mountain portion 32 by But moving die 10 and is fixed The exhaust of mould 12 is opposite with mountain valley portion 33 and is formed.
In the present embodiment, exhaust paddy mountain portion 32, exhaust mountain valley portion 33 are formed in six positions, that is, are formed with six It is a.Therefore, the number of cooling exhaust portion 30 and aftermentioned overflow part 34 is also six.
One end of cooling exhaust portion 30 is connected to via overflow part 34 with the end of type chamber 16.On the other hand, Gu Shan is used in exhaust Portion 32, exhaust mountain valley portion 33 extend to the side of But moving die 10, and therefore, cooling exhaust portion 30 is in stent 12 and But moving die 10 Side to atmosphere open wide.
Overflow part 34 includes melt reservoir 36, the first melt filling part positioned at the downstream side of the melt reservoir 36 38 and the second melt filling part 40.Melt reservoir 36 is connected with the outlet of type chamber 16, and towards the type chamber base of protrusion 24 The base end side extension of end side, type chamber recess portion 26.That is, the extending direction of melt reservoir 36 and the parallel direction along joint surface It is orthogonal.
In the terminal part of type chamber 16, the melt outlet 42 formed along joint surface is big in the length direction of melt reservoir 36 Cause middle part opening.Here, melt outlet 42 is formed as wide as shown in Fig. 3 using the direction orthogonal with joint surface as visual angle Degree becomes narrow with towards overflow part 34.On the other hand, Fig. 2 such as using the direction parallel with joint surface as visual angle can Know, is provided with gradient in a manner of with being unfolded towards overflow part 34 in melt outlet 42.By the gradient, can with make width Spend it is narrow independently, maintain melt outlet 42 cross-sectional area constant.Moreover, as shown in Fig. 2, due in melt outlet 42 38 side of the first melt filling part be provided with inclined surface, therefore, as will be described later, the melt L derived from the melt outlet 42 It is most of towards the first melt filling part 38.
First melt filling part 38 and the second melt filling part 40 are the part be detained and cooled and solidified for melt L, edge The direction orthogonal with joint surface extend.That is, the first melt filling part 38 is in a manner of far from joint surface towards But moving die 10 Internal stretch But moving die side melt filling part, the second melt filling part 40 be by far from a manner of joint surface towards stent The stent side melt filling part of 12 internal stretch.
First melt filling part 38 is to be linearly connected to the downstream side of melt reservoir 36.In the first melt filling part 38 It is middle to receive equipped with the first bushing 44 abutted for the first spacer 43, and the first knockout pin 46 slidably inserts between first freely Spacing body 43 and the first bushing 44.Since there are the first bushings 44, the capacity of the first melt filling part 38 is made to be less than melt reservoir 36 capacity.
12 side of stent of melt reservoir 36 is bent in a manner of extending along joint surface in substantially 90 °.Second melt Filling part 40 is set to the slightly downstream side of the bending part 48, as described above, towards stent 12 in a manner of far from joint surface Inside.Therefore, the first melt filling part 38 is not located along the same line with the second melt filling part 40.That is, the first melt is filled out The position for filling portion 38 and the second melt filling part 40 becomes asymmetric.
It receives in the second melt filling part 40 equipped with the second bushing 52 abutted for the second spacer 50.Moreover, second pushes away Pin 54 is slidably inserted freely in the second spacer 50 and the second bushing 52 out.
It is formed with downstream side on joint surface to be connected to the second melt filling part 40, and upstream side and cooling exhaust portion 30 The communication path 56 of connection.It is formed with the joint surface and type chamber protrusion 24 of the second melt filling part 40 and cooling exhaust portion 30 The joint surface of top surface is compared, the position in plan view in recess, therefore so that communication path 56 is located relative to melt and gone out The positions that mouth 42 is deviated to 12 side of stent.
The structure of casting device involved in present embodiment is constituted as described above substantially, then, using with it is logical The relationship for the casting method that the casting device is carried out is crossed to illustrate its function and effect.
In order to be cast, firstly, it is mobile in a manner of close to stent 12 to make But moving die 10, and molded.It is tied Fruit passes through type chamber forming portion 14a, 14b and type chamber forming portion shape forming cavity 16.Meanwhile also forming overflow part 34 and cooling exhaust Portion 30.
Then, the melt L of the metals such as aluminium is supplied from cast gate 20.Melt L is assigned via runner 19, moreover, from each runner 19 importing type chambers 16.Accordingly, start to fill melt L to type chamber 16.Melt L using runner 19 as upstream side, using terminal part as Most downstream side and flowed in type chamber 16.
If importing the melt L of specified amount into type chamber 16, melt L is exported from melt outlet 42.In other words, it flows into and overflows Stream portion 34.The melt L that can speculate that the overflow goes out is flowed by following.
As described above, the width of melt outlet 42 becomes narrow (referring to Fig. 3) with towards overflow part 34.Therefore, it melts Body L diffusion immediately after entering the bigger melt reservoir 36 of capacity (referring to Fig. 2).I.e., it is difficult to advance to straight ahead, And cause convection current as shown by the arrows.As a result, melt L is temporarily lodged in melt reservoir 36.After this, Melt L is full of the melt reservoir 36 on one side, makes a part by inclined surface set by melt outlet 42 on one side, thus by leading Enter 38 side of the first melt filling part to be linearly connected with melt reservoir 36.
In this way, becoming narrow and making the width of melt outlet 42 with towards overflow part 34, spread melt L on one side Melt reservoir 36 is flowed on one side, therefore is easy on one side temporarily lodge in melt reservoir 36 while to the first melt filling part 38 Guidance.Further, since being provided with gradient at melt outlet 42, therefore it can ensure that the cross-sectional area of the melt outlet 42 is permanent It is fixed, and exhaust velocity can be made constant.
It is received in the first melt filling part 38 and first bushing 44 is housed.Therefore, melt L enters the hollow interior of the first bushing 44 Portion, and stopped by the top of the first knockout pin 46.
In the case where the amount for the melt L that overflow goes out is more than the volume of melt reservoir 36 and the first melt filling part 38, The melt L that the melt L of excess quantity will be filled with the first melt filling part 38 squeezes out or is directly toward joint side.What is be extruded is molten Body L or the melt L for being directly toward joint side flowing are imported into the second melt filling part 40 by bending part 48.In the process In, the direction of travel of melt L is filled when mobile from melt reservoir 36 to bending part 48 and from bending part 48 to the second melt Portion 40 has changed substantially 90 ° when mobile.
With bending part 48 is passed through in this way, decline the flowing velocity of melt L.Thus, it is easy to prevent melt L from leaking, i.e., So-called flash.Moreover, in this case, melt L is not easy to flow from overflow part 34 to communication path 56.In other words, it is easy to make Melt L is filled in the second melt filling part 40.
It is received in the second melt filling part 40 and second bushing 52 is housed.Therefore, melt L enters the hollow interior of the second bushing 52 Portion, and stopped by the top of the second knockout pin 54.
Melt reservoir 36 is located near melt outlet 42, and the first melt filling part 38 and the second melt filling part 40 are located near melt delay portion.Therefore, the melt L near melt outlet 42 is melt body reservoir 36, the first melt is filled out Fill the melt L heating in portion 38 and the second melt filling part 40.Therefore, because can be avoided the temperature of melt L in melt outlet Sharply decline near 42, therefore is able to maintain that riser effect.
If the further overflow of melt L, melt L enters communication path 56.According to circumstances, cooling exhaust is also reached sometimes Portion 30.
As described above, in the present embodiment, melt L is melt body reservoir 36 and temporarily accumulates.After this, due to making The position of one melt filling part 38 and the second melt filling part 40 is asymmetric position, therefore the major part of melt L flows into first First melt filling part 38 then flows into the second melt filling part 40.That is, melt L is successively flowed into from the first melt filling part 38 Second melt filling part 40.
In this way, the melt L that overflow goes out is lowered by flowing velocity and lodging in melt reservoir 36.Moreover, herein It is stagnant in overflow part 34 later due to successively being flowed via the first melt filling part 38 and the second melt filling part 40 Stay longer time.Therefore, the temperature of melt L relatively quickly declines.
Moreover, can be stored largely by melt reservoir 36, the first melt filling part 38 and the second melt filling part 40 Melt L.Therefore, the flowing velocity that the melt L of cooling exhaust portion 30 is entered into the melt L of communication path 56, sometimes is abundant Ground reduces, and temperature fully declines, and its amount is few.Therefore, the melt of communication path 56, cooling exhaust portion 30 is reached L is cooled and solidified in a short time.
Therefore, it does not need especially that cooling exhaust portion 30 is made to form large capacity.Correspondingly, it can be realized cooling exhaust portion 30 Miniaturization.Therefore, because can be realized miniaturization/lightweight of the stent 12 as mold, But moving die 10, therefore can Cost needed for reducing mold.
As shown in figure 4, cooling and solidifying by the melt L for being filled in type chamber 16, two sides shell 18a, 18b can be obtained As cast member.Side shell 18a, 18b are connected by craftsmanship position 22.In addition, as shown in Figure 4 and Figure 5, in side shell The overflow part for being formed through the melt L cooling and solidifying that overflow part 34 is detained on 18a, 18b and being formed corresponds to portion 60.Overflow part Correspondence portion 60 includes that melt reservoir corresponds to portion 62, the first melt filling part corresponds to portion 64, the second melt filling part corresponds to portion 66 Portion 68 is corresponded to communication path (referring to Fig. 5).
And the direction by making But moving die 10 to separate stent 12 is mobile after die sinking, cast member is by the first knockout pin 46, second knockout pin 54 etc. is pressed and is demoulded.Moreover, corresponding to portion 60 by excision craftsmanship position 22, overflow part, can obtain Shape is similar to side shell 18a, 18b of final products.
The present invention is not particularly limited to above-mentioned embodiment, without departing from the spirit and scope of the invention, can It makes various changes.
For example, it is also possible to configure the first melt filling part 38 symmetrically with the second melt filling part 40.Alternatively, it is also possible to It is contrary to the above, the first melt filling part 38 is set in stent 12, and the filling of the second melt is arranged on But moving die 10 Portion 40.
Furthermore, it is also possible to which the passage path of communication path 56 is made to be set smaller than the first melt filling part 38 and the second melt The passage path of filling part 40.Accordingly, melt L flows after being filled into the first melt filling part 38 and the second melt filling part 40 Enter 56 side of communication path.That is, making the inflow sequence of melt L becomes more reliable.
