Abstract
The invention provides a die-casting mould provided with an air receiving part. A plurality of air receiving parts are recesses located in at least one molding face forming a profile cavity. When a molten metal is injected into the profile cavity through a pouring port and fills the profile cavity, each air receiving part in the air receiving parts is covered and sealed by the molten metal in the state that air is received in the each air receiving part. So the contact area between the molten metal filled in the profile cavity and the molding face is reduced, and then adhesion of the molten metal on the molding face is also reduced. Consequently, when the molten metal while curing or a formed metal product is separated from the molding face, coking and sticking phenomena can be prevented. Furthermore, when the molten metal is injected into the profile cavity and flows, a friction force between the molten metal and the molding face is also reduced due to the air received in the air received parts.
Description
Technical field
One or more illustrative embodiments relates to compression mod, more specifically, relates to the compression mod with modified node method, in compression mod, can reduce the contact area between the motlten metal that loads in die cavity and molded surface.
Background technology
Compression mod has been widely used in large-scale production metal product.The essential structure of an example of these compression mods is illustrated in Fig. 1.
The illustrated compression mod 1A of Fig. 1 comprises: fixed die 1, and this fixed die 1 is fixed to die casting machine (not shown); With But moving die 2, this But moving die 2 to be arranged on die casting machine and along a direction L move with fixed die 1 close contact or spaced apart from fixed die 1.Fixed die 1 has the first molded surface 1a, and But moving die 2 has and the second molded surface 2a faced by the first molded surface 1a.Even if when fixed die 1 and But moving die 2 intimate contact with one another time, the first molded surface 1a and the second molded surface 2a is also not in actual contact each other, but is spaced apart from each other.Space between first molded surface 1a and the second molded surface 2a is die cavity 3, and die cavity 3 is the spaces forming metal product wherein.Reference numeral S is mounted in fixed die 1 place thus in die cavity 3, injects the injection cylinder of motlten metal M1, and Reference numeral 3a is cast gate, and this cast gate is the motlten metal injection path be communicated with die cavity 3.
The die cavity 3 of compression mod 1A comprises first area A1 and second area A2.The distance W1 of width namely in the A1 of first area on a direction L between the first molded surface and the second molded surface of first area A1 is greater than the distance W2 of width namely in second area A2 on a described direction L between the first molded surface and the second molded surface of second area A2.Thus, in the metal product M (see Fig. 3) formed in die cavity 3, the part be formed in the A1 of first area is thicker than the part be formed in second area A2.
In order to form metal product M by use compression mod 1A, as shown by the solid lines of fig. 1, make But moving die 2 and fixed die 1 close contact, and by using injection cylinder S to inject high-temperature molten metal M1 by cast gate 3a in die cavity 3, thus motlten metal M1 is filled in die cavity 3.The motlten metal M1 be filled in die cavity 3 cools along with the time and solidifies, and forms the shape metal product M corresponding with die cavity 3, as shown in Figure 2.Like this, after define metal product M in die cavity 3, But moving die 2 is separated from fixed die 1, and formed metal product M is separated from fixed die 1 and But moving die 2.When by metal product M from after fixed die 1 and But moving die 2 are separated, But moving die 2 is moved into and fixed die 1 close contact, and carries out the operation of formation metal product M described above repeatedly.
The motlten metal M1 be injected in die cavity 3 contacts with the second whole molded surface 2a with the first whole molded surface 1a.Like this, the motlten metal M in die cavity 3 contacts with the second molded surface 2a with the first whole molded surface 1a, thus produces following problem:
First, the high-temperature molten metal M1 filled in die cavity 3 cools and solidifies and shrink in die cavity 3.In this contraction process, or terminate after shaping and motlten metal M1 is formed as metal product M at high-temperature molten metal M1, the motlten metal M1 of solidification separates from the first molded surface 1a and/or the second molded surface 2a.But, because motlten metal M1 all contacts with the second molded surface 2a with the first whole molded surface 1a, motlten metal M1 and the adhesion between the first molded surface 1a and the second molded surface 2a larger.Thus, when the motlten metal M1 of solidification as mentioned above separates from the first molded surface 1a and the second molded surface 2a, or when metal product M terminate shaping and metal product M is separated from fixed die 1 with But moving die 2 time, motlten metal M1 or whole metal product M is not separated with the second molded surface 2a completely with the first molded surface 1a, and a part of motlten metal M1 or metal product M is stuck and coking.Especially in the region (first area A1) that the thicker forming metal product M is divided this phenomenon and motlten metal coking and to cling the generation of phenomenon more remarkable.
In addition, usually in die cavity 3, motlten metal M1 is injected with the speed of tens meters per second, thus Fast Filling die cavity 3 in the given time.But when injecting in die cavity 3 and loading motlten metal M1, due to the frictional force between motlten metal M1 and the first molded surface 1a and the frictional force between motlten metal M1 and the second molded surface 2a, the speed of motlten metal M1 reduces.If the speed of motlten metal M1 reduces thus, then motlten metal M1 can not flow swimmingly completely in die cavity 3, and cool and solidify, thus, creating the defect (so-called non-filling defect) that motlten metal M1 fails to be filled in completely in die cavity 3.
Summary of the invention
One or more embodiment comprises the compression mod with following structure, in the structure shown here, reduce the contact area between motlten metal and molded surface of loading in die cavity, thus the motlten metal be just cured or the metal product formed are separated from the molded surface of mould, coking can be prevented and cling phenomenon, and when to type intracavitary administration motlten metal, the friction between molded surface and motlten metal can also be reduced.

First, with reference to Fig. 4 A and 4B, be similar to referring to figs. 1 through 3 describe according in the compression mod 1A of prior art, comprise the fixed die 10 with the first molded surface 11 and the But moving die 20 with the second molded surface 21 according to the compression mod 100 of current embodiment.Fixed die 10 is fixed to die casting machine (not shown).But moving die 20 is arranged to move on a direction L under the state of this But moving die 20 towards fixed die 10, instead of is moved by die casting machine.That is, But moving die 20 can along a described direction L move with fixed die 10 close contact or spaced apart from fixed die 10.
When But moving die 20 and fixed die 10 close contact, between the first molded surface 11 and the second molded surface 21, form empty space, i.e. die cavity 30.Die cavity 30 is such spaces: use the motlten metal M1 that sprays of ejection cylinder S sprayed for motlten metal being arranged on fixed die 10 place to be loaded within this space.The shape of die cavity 30 corresponds to the metal product that will be formed.Cast gate 31 is connected to die cavity 30, when cast gate 31 is for spraying motlten metal M1 in die cavity 30 via path.
Die cavity 30 comprises first area A1 and second area A2.Distance W1 in the A1 of first area on a direction L between the first molded surface 11 and the second molded surface 21 is greater than the distance W2 in second area A2 on a described direction L between the first molded surface 11 and the second molded surface 21.Thus, in the metal product formed in die cavity 30, the part be formed in the A1 of first area is thicker than the part be formed in second area A2.
Different from the compression mod according to prior art, comprise multiple air receiver part 115 according to the compression mod 100 of current embodiment, these air receiver parts 115 are depressions being arranged in first molded surface 111 of first area A1 of the first molded surface 11 at fixed die 10.Comprise multiple air receiver part 215 further according to the compression mod 100 of current embodiment, these air receiver parts 215 are depressions being arranged in second molded surface 211 of first area A1 of the second molded surface 21 at But moving die 20.
Multiple air receiver part 125 and multiple air receiver part 225 is also comprised according to the compression mod 100 of current embodiment, described multiple air receiver part 125 is the depressions being arranged in first molded surface 112 of second area A2 at the first molded surface 11, and described multiple air receiver part 225 is the depressions being arranged in second molded surface 212 of second area A2 at the second molded surface 21.
Hereinafter, the air receiver part 115 and 215 being arranged in first area A1 is called " the first air receiver part 115 and 215 ", and the air receiver part 125 and 225 being arranged in second area A2 is called " the second air receiver part 125 and 225 ".
The first air receiver part 115 and 215 and the second air receiver part 125 and 225 is described in detail subsequently with reference to Fig. 5 and 6.
Each in first air receiver part 115 and 215 and the second air receiver part 125 and 225 has cylinder form and same depth.Each degree of depth in first air receiver part 115 and 215 and the second air receiver part 125 and 225 can in the scope from 0.1mm to 0.5mm.If each degree of depth in the first air receiver part 115 and 215 and the second air receiver part 125 and 225 is less than 0.1mm, be then not easy to realize after a while by the friction reducing effect described with adhere to reducing effect.If each degree of depth in the first air receiver part 115 and 215 and the second air receiver part 125 and 225 is greater than 0.5mm, then probably unnecessarily increase for the formation of time of described air receiver part or work.First air receiver part 115 and 215 and the second air receiver part 125 and 225 can by such as to etch or spark machined is formed.
First air receiver part of the upstream side of in the first air receiver part 115 and 215, to be arranged in the motlten metal M1 injected to die cavity 30 by cast gate 31 flow direction F (is positioned at the first air receiver part of the downside of the dotted line Z of Fig. 5 and 6; Hereinafter, can be called simply " upstream first air receiver part ") than in the first air receiver part 115 and 215, the first air receiver part in the downstream of the flow direction F that is arranged in the motlten metal M1 injected to die cavity 30 by cast gate 31 (is positioned at the first air receiver part of the upside of the dotted line Z of Fig. 5 and 6; Hereinafter, can be called simply " downstream first air receiver part ") arrange more compactly.In detail, as illustrated in Figures 5 and 6, the centre distance P111 between adjacent upstream first air receiver part and P211 is less than centre distance P112 between adjacent downstream first air receiver part and P212.
In second area A2, the second air receiver part of the upstream side of in the second air receiver part 125 and 225, to be arranged in the motlten metal M1 injected to die cavity 30 by cast gate 31 flow direction F (is positioned at the second air receiver part of the downside of the dotted line Z of Fig. 5 and 6; Hereinafter, can be called simply " upstream second air receiver part ") than in the second air receiver part 125 and 225, the second air receiver part in the downstream of the flow direction F that is positioned at the motlten metal M1 injected to die cavity 30 by cast gate 31 (is positioned at the second air receiver part of the upside of the dotted line Z of Fig. 5 and 6; Hereinafter, can be called simply " downstream second air receiver part ") arrange more compactly.In detail, as illustrated in Figures 5 and 6, the centre distance P121 between adjacent upstream second air receiver part and P221 is less than centre distance P122 between adjacent downstream second air receiver part and P222.
First air receiver part 115 and 215 to the second air receiver part 125 and 225 is arranged more compactly.In detail, the centre distance P112 between the centre distance P111 between adjacent upstream first air receiver part and P211 and adjacent downstream first air receiver part and P212 is less than centre distance P122 between centre distance P121 between adjacent upstream second air receiver part and P221 and adjacent downstream second air receiver part and P222.
Centre distance P111 between adjacent upstream first air receiver part and P211 can be equal to or less than the diameter d 111 of upstream first air receiver part and about 1.5 times of d211.If the centre distance P111 between the air receiver part of adjacent upstream first and P211 is greater than the diameter d 111 of upstream first air receiver part and 1.5 times of d211, then after a while the friction reducing effect of the upstream side of the first area A1 of description and adhesion reducing effect may be significantly reduced.
In current embodiment, represent the dotted line Z being formed with border between the region (upstream region) of upstream first air receiver part and upstream second air receiver part and the region (downstream area) being formed with downstream first air receiver part and downstream second air receiver part, what be arranged in the first molded surface 11 and the second molded surface 21 each to inject the centre on the flow direction F of motlten metal M1 to die cavity 30 by cast gate 31.But this is only an example, the position of dotted line Z on the flow direction F of motlten metal M1 suitably can be determined according to the whole shape of die cavity 30 and die cast condition.
The diameter d 111 of upstream first air receiver part and d211 can be greater than diameter d 112 and the d212 of downstream first air receiver part, and the diameter d 121 of upstream second air receiver part and d221 can be greater than diameter d 122 and the d222 of downstream second air receiver part.In addition, the diameter d 111 of upstream first air receiver part and the diameter d 112 of d211 or downstream first air receiver part and d212 can be greater than the diameter d 121 of upstream second air receiver part and the diameter d 122 of d221 or downstream second air receiver part and d222.
Diameter d 111, d112, d211, d212, d121, d221, d122 and d222 of all air receiver parts suitably can set when considering die cast condition.But, in order to effectively prevent motlten metal M1 to be introduced in the first and second air receiver parts 115,215,125 and 225, the diameter d 111 of all air receiver parts, d112, d211, d212, d121, d221, d122 and d222 can be configured to be equal to or less than 0.5mm.This is because, when the diameter d 111 of air receiver part, d112, d211, d212, d121, d221, d122 and d222 are greater than 0.5mm, by the possibility increasing motlten metal M1 the air be easily introduced in air receiver part and air receiver part will be discharged from described air receiver part.The minimum of a value of the diameter of air receiver part suitably can set according to design, but considers that the convenience forming air receiver part can be set greater than or be greater than 0.3mm.
The basic operation forming metal product by using the compression mod 100 with above-mentioned structure with pass through to use referring to figs. 1 through 3 describe to form the basic operation of metal product according to the compression mod 1A of prior art identical.
That is, when using the compression mod 100 according to current embodiment, also But moving die 20 and fixed die 10 close contact is made, as shown in the solid line in Fig. 4 A, and by using ejection cylinder S to spray high-temperature molten metal M1 by cast gate 31 in die cavity 30, thus high-temperature molten metal is seated in die cavity 30.In die cavity 30, the motlten metal M1 of filling cools along with the time and solidifies, and becomes the shape metal product corresponding with die cavity 30.
As mentioned above, because the first air receiver part 115 and 215 and the second air receiver part 125 and 225 are formed with small diameter (being equal to or less than 0.5mm), thus when the high-temperature molten metal M1 sprayed in die cavity 30 by the cast gate 31 in die cavity 30 is flowed and is filled in die cavity 30 in die cavity 30, motlten metal M1 is not easy to be introduced in the first and second air receiver parts 115,215,125 and 225.Motlten metal M1 is not introduced in the first and second air receiver parts 115,215,125 and 225, but as shown in Figure 8, under the state that air G is received in the first and second air receiver parts 115,215,125,225 wherein, the first and second air receiver parts 115,215,12 and 225 are covered by high-temperature molten metal M1 and seal.Be melted metal M 1 and be sealed in air G in the first and second air receiver parts 115,215,125 and 225 (see Fig. 8, conveniently, illustrate only the air in the first air receiver part 115 and 215 in fig. 8) heated by high-temperature molten metal M1 and there is power (thermal expansion force).
The thermal expansion force being received in the air G in the first air receiver part 115 and 215 and the second air receiver part 125 and 225 is applied on motlten metal M1.Such as, the thermal expansion force being received in the air in the first air receiver part 115 of fixed die 10 is applied to motlten metal M1 on the FH1 of direction, and this direction is applied to the first molded surface with by motlten metal M1 and between motlten metal M1 and the first molded surface 111, produces the contrary direction of the action direction FM1 of the normal force of frictional force.Similarly, the thermal expansion force being received in the air in the air receiver part 215 of But moving die 20 is applied to motlten metal M1 on the FH2 of direction, and this direction is applied to the second molded surface with by motlten metal M1 and between motlten metal M1 and the second molded surface 211, produces the contrary direction of the action direction FM2 of the normal force of frictional force.In addition, the action direction being received in the thermal expansion force of the air in the second air receiver part 125 is the direction contrary with the action direction producing the power of frictional force between motlten metal M1 and molded surface 112 and 212.
That is, the thermal expansion force of the air G during to be received in the first air receiver part 115 and 215 and the second air receiver part 125 and 225 each be applied to motlten metal M1 and the first and second molded surfaces 111,211, produce between 112 and 212 on the contrary direction of the action direction of the power of frictional force.Thus, when motlten metal M1 flows in die cavity 30, owing to being received in the thermal expansion force of the air in each air receiver part in the first and second air receiver parts 115,215,125 and 225, reduce motlten metal M1 and each the first and second molded surface 111,211, frictional force between 112 and 212.As a result, the flowing of the motlten metal M1 in die cavity 30 is carried out swimmingly, thus motlten metal M1 can easily fully be seated in die cavity 30.
Motlten metal M1 at first area A1 (in the A1 of this first area, distance W1 between first molded surface 111 and the second molded surface 112 is larger) in flow cross section area be greater than the flow cross section area of motlten metal M1 in second area A2 (in this second area A2, the distance W2 between the first molded surface 111 and the second molded surface 112 is less).Thus, compared with second area A2, the speed of the motlten metal M1 in the A1 of first area is lower, and pressure increases.As a result, compared with second area A2, the frictional force in the A1 of first area increases.But, the compactedness of the first air receiver part 115 and 215, the quantity of the first air receiver part 115 and 215 namely in per unit area higher than the quantity of the second air receiver part 125 and 225 in per unit area, thus the amount (quantity of air receiver part) producing the air of thermal expansion force in the A1 of first area than increasing further in second area A2.That is, in the A1 of first area, the power offsetting the frictional force between motlten metal M1 and molded surface increases further.Thus, can more effectively reduce motlten metal and there is the friction between the molded surface in the first area A1 of larger frictional force.
In addition, the frictional force between motlten metal M1 and molded surface for longer periods applies closer to upstream side along with motlten metal.Thus, in current embodiment, if upstream first air receiver part is arranged more compactly than downstream first air receiver part, and upstream second air receiver part is arranged more compactly than downstream second air receiver part, then the amount (quantity of air receiver part) producing the air of thermal expansion force increases further at upstream side.Thus, the power of the frictional force offsetting upstream side is further increased.Thus, that the long period that more effectively can reduce upstream side applies, larger frictional force.The diameter d 11 of upstream first air receiver part and d211 are greater than diameter d 112 and the d212 of downstream first air receiver part, and the diameter d 121 of upstream second air receiver part and d221 are greater than diameter d 122 and the d222 of upstream second air receiver part, thus more effectively can reduce the frictional force of upstream side.
The motlten metal M1 be fully seated in die cavity 30 little by little cools and solidifies, and becoming metal product.Motlten metal M1 shrinks constantly, until it becomes metal product.The volume of motlten metal M1 while shrinking (it also refers to be under semi-molten state along with passage of time or motlten metal M1 under having cured state) reduces, thus is separated from each first molded surface 11 with the second molded surface 21 by motlten metal M1.In this case, in the compression mod (being all formed with the compression mod of the first and second air receiver parts 115,215,125 and 225 in the first molded surface 11 and the second molded surface 21) according to current embodiment, with compared with the compression mod without air receiver part of prior art, the contact surface between the motlten metal M1 of filling in die cavity 30 and molded surface decreases the area of the first and second air receiver parts 115,215,125 and 225.Like this, the contact surface between the motlten metal M1 of filling in die cavity 30 and molded surface reduces, thus also reduces with the adhesion of motlten metal M1.Thus, when motlten metal M1 shrinks, can easily it be separated from the first molded surface 11 with the second molded surface 21.In addition, even if when the metal product fully solidified by motlten metal M1 is separated from compression mod, also can easily this metal product be separated from the first molded surface 11 with the second molded surface 21.Thus, effectively can prevent the motlten metal M1 coking of solidifying or fully solidifying or be bonded on the first molded surface 11 and the second molded surface 21.
When motlten metal M1 cools and solidifies, the amount of contraction being seated in the motlten metal M1 in first area A1 (the distance W1 wherein between the first molded surface 11 and the second molded surface 21 is larger) is greater than the amount of contraction of the motlten metal M1 be seated in second area A2 (the distance W2 wherein between the first molded surface 11 and the second molded surface 21 is less).Thus, have so a kind of may, namely in the A1 of first area than in second area A2, motlten metal M1 zoom frequently occurring and the coking be bonded on molded surface and cling phenomenon.
But in the present embodiment, the compactedness of the air receiver part 115 and 215 in the A1 of first area is higher than the compactedness of the air receiver part 125 and 225 in second area A2.Thus, further increase the adhesion reducing effect of the motlten metal M1 in the A1 of first area, thus can more effectively suppress the coking of motlten metal M1 and cling phenomenon.
In addition, when the diameter d 111 of the air receiver part in the A1 of first area, d112, d211 and d212 are greater than diameter d 121, d122, d221 and d222 of the air receiver part in second area A2, the adhesion between motlten metal M1 and molded surface and friction more effectively can be reduced in the A1 of first area.
In the present embodiment, the diameter of the first and second air receiver parts 115,215,125 and 225 is formed to be equal to or less than 0.5mm, thus suppresses motlten metal M1 to enter in air receiver part.But, if suppress motlten metal M1 to enter in air receiver part, then can consider that the diameter of air receiver part can be greater than 0.5mm.But, when the diameter of air receiver part is greater than 0.5mm, motlten metal M1 is easily introduced in be had in larger-diameter air receiver part and is loaded, thus adds the possibility that the air (namely producing the air of thermal expansion force) in air receiver part is discharged.As a result, the diameter of air receiver part can be equal to or less than 0.5mm.
In addition, in embodiment described above, the first and second air receiver parts 115,215,125 and 225 can have cylinder form.But, if be melted metal M 1 sealing producing the first and second air receiver parts 115,215,125 and 225 under state that the air of thermal expansion force is received in the first and second air receiver parts 115,215,125 and 225, then air receiver part can have other shape, such as, hemispherical or rectangular box.
In embodiment described above, air receiver part is all formed in the molded surface (the first molded surface) of fixed die and the molded surface (the second molded surface) of But moving die.But if necessary, air receiver part also can only be formed in the molded surface of fixed die or in the molded surface of But moving die.
In addition, in embodiment described above, described die cavity comprises first area described above and second area.But design of the present invention is also applicable to wherein compression mod to be had and does not form above-mentioned second area and the situation only forming the die cavity of first area.That is, design of the present invention can be suitable for the situation that wherein compression mod has the identical die cavity of distance between the first molded surface and the second molded surface.
As mentioned above, according to above one or more illustrative embodiments, the contact area be seated between motlten metal in die cavity and molded surface reduces, thus the adhesion of motlten metal on molded surface also reduces.As a result, when the motlten metal solidified or the metal product formed are separated from molded surface, coking can be prevented and cling phenomenon.In addition, when motlten metal to be injected in die cavity and to flow, the frictional force between motlten metal and molded surface is also reduced due to the air be received in air receiver part.
