Detailed description of the invention
Below, with reference to Fig. 1, the casting as involved in the present invention is described with the surface-treated metal mould 1 of an embodiment of parts.
As shown in Figure 1, surface-treated metal mould 1 possesses as the metal pattern 10 of mother metal and is formed on the carbon film 20 in the forming face of metal pattern 10.
Metal pattern 10 is, the metal pattern using in die-cast etc., and one surface (being upper surface in Fig. 1) is formed forming face.Metal pattern 10 is produced out by powder melts lamination, and its surface is due to multiple small concavo-convex coarse surfaces characteristic that present.
Herein, powder melts lamination refers to, by the stacked metal dust by being scheduled to (for example, the powder of Maraging steel) form layer, and utilize laser and make the predetermined portions melting of each layer, thereby the technology that the goods of the shape to expection carry out appearance, and be known as a method in rapid prototyping manufacture (Rapid Prototyping).
In powder melts lamination, because metal dust is melted and solidifies, therefore on the surface of metal pattern 10, be formed with multiple small concavo-convex, thereby the surface of metal pattern 10 presents coarse surface characteristic.
Being formed on the lip-deep multiple small concavo-convex of the metal pattern 10 produced by powder melts lamination is made up of multiple juts 1111.
In addition, below for convenience of explanation, only the multiple juts 1111 that form in a forming face surperficial part, metal pattern 10 of metal pattern 10 are described.
Jut 11 from the forming face of metal pattern 10 laterally (upside Fig. 1) outstanding, and there is reverse tapered shapes (what is called, undercutting).Specifically, jut 11 is formed, and along with trend towards outstanding end (upper end in Fig. 1) from its base end part (bottom Fig. 1), it is large that width dimensions (length on the left and right directions in Fig. 1) becomes gradually.In other words, the distance between adjacent jut 1111 diminishes gradually along with trending towards the outside (upside in Fig. 1) of metal pattern 10.
So, the forming face of metal pattern 10 is formed, the male and fomale(M&F) being made up of multiple juts 1111., the forming face of metal pattern 10 is by the multiple small concavo-convex formation that is reverse tapered shapes (what is called, undercutting).
Carbon film 20 is, for realizing the ejection resistance in the forming face that reduces metal pattern 10 and preventing the fine and close tunicle of molten damage etc.Carbon film 20 in present embodiment is, the carbon film that contains at least one nano-sized carbon class.
At this, the nano-sized carbon class in the present invention refers to, the trickle fibrous nano-sized carbon classes such as carbon nano-fiber, CNT, carbon nanocoil and carbon nano wire.
For example, can form carbon film 20 by the multiple carbon nano-fibers that are formed in the forming face of metal pattern 10, or form carbon film 20 etc. by the multiple CNTs that are formed in the forming face of metal pattern 10.And, can also be in the fibrous nano-sized carbon class of carbon nano-fiber etc., the roughly spherical fullerene that coating is made up of multiple carbon atoms.
Carbon film 20 is formed, and in the forming face of metal pattern 10, covers multiple juts 1111, and is formed, the space between the adjacent jut 1111 of landfill.
Therefore, between multiple juts 1111 and carbon film 20, can produce anchoring effect.
Specifically, because multiple juts 1111 are outstanding upward from the forming face of metal pattern 10, therefore limit along the forming face with respect to metal pattern 10 and movement in parallel direction (left and right directions in Fig. 1), carbon film 20 by multiple juts 1111.And, because jut 11 has reverse tapered shapes (what is called, undercutting), therefore limit along the forming face with respect to metal pattern 10 and movement in the direction (above-below direction in Fig. 1) of orthogonal, carbon film 20 by multiple juts 1111.
Therefore, by the anchoring effect producing between multiple juts 1111 and carbon film 20, thereby can suppress the situation that carbon film 20 is peeled off from the forming face of metal pattern 10.
As mentioned above, in surface-treated metal mould 1, the forming face of metal pattern 10 is formed the male and fomale(M&F) being made up of multiple juts 1111 with reverse tapered shapes (what is called, undercutting), and in this forming face, is formed with carbon film 20.
Thus, can make to increase compared with the surface area of the surface area of forming face of metal pattern 10 and the forming face of existing metal pattern (by bead processed forming face etc.), thereby can in the forming face of metal pattern 10, generate more nano-sized carbon class.
Therefore, carbon film 20 can be made as to firmly combination with respect to the combination of the forming face of metal pattern 10, from and can suppress the situation that carbon film 20 is peeled off from the forming face of metal pattern 10.
In addition, by more nano-sized carbon class is formed in the forming face of metal pattern 10, thereby can form the there is thicker thickness carbon film 20 of (size up and down in Fig. 1).
Therefore, the thermal insulation of the forming face of the surface-treated metal mould 1 can improve casting time, thus realize flowing of good motlten metal.And, because releasing agent is kept well by carbon film 20, therefore can improve the oiliness in the forming face of surface-treated metal mould 1.
In addition, although in the present embodiment, tunicle involved in the present invention is made as to the carbon film 20 that contains at least one nano-sized carbon class, is not limited thereto.
For example, as tunicle involved in the present invention, can adopt the fine and close tunicle of hard chrome plating or scales etc.
Below, with reference to Fig. 2～Fig. 5, the casting as involved in the present invention is described with the S1 of a manufacturing process embodiment, surface-treated metal mould 1 of the manufacture method of parts.
As shown in Figure 2, the S1 of manufacturing process possesses appearance operation S10 and tunicle formation operation S20.
Appearance operation S10 is, produces the operation of metal pattern 10 by powder melts lamination, and described metal film 10 has by the forming face of multiple small concavo-convex formation that is reverse tapered shapes (what is called, undercutting).
In appearance operation S10, by powder melts lamination, produce metal film 10 by the metal dust of Maraging steel etc., described metal film 10 has the forming face that is formed with multiple juts 1111.
It is in the forming face of metal pattern 10, to form the operation of carbon film 20 that tunicle forms operation S20.
Form in operation S20 at tunicle, by supply with the reacting gas of acetylene etc. of the raw material that becomes carbon film 20 under the atmosphere of the inert gas of nitrogen etc. in atmosphere furnace, and metal pattern 10 is heated, thereby form carbon film 20 in the forming face of metal pattern 10.
Be preferably, form carbon film 20 in the forming face of metal pattern 10 in atmosphere furnace time, implement for making the curing Ageing Treatment of metal pattern 10 simultaneously.
Specifically, as shown in Figure 3, in by atmosphere furnace, be made as nitrogen (N
2) after atmosphere, supply with acetylene (C
2h
2) and ammonia (NH
3), and be warming up to 570 DEG C, and under the state of this maintenance temperature, metal pattern 10 is heated four hours.
So, in the forming face of metal pattern 10, form carbon film 20, and be implemented Ageing Treatment on metal pattern 10.
As shown in Figure 4, all the time, the Ageing Treatment of metal pattern by implementing metal pattern heating for four hours at 570 DEG C.
In the present embodiment, form in operation S20 at tunicle, implement the heating of metal pattern 10 with the temperature identical with the Ageing Treatment of existing metal pattern and time.
Therefore, by forming operation S20 through tunicle, thereby metal pattern 10 has been implemented to Ageing Treatment.
As shown in Figure 5, all the time, the formation of the carbon film in the forming face of metal pattern is lower and effective in the temperature of the Ageing Treatment lower than metal pattern (480 DEG C), and the temperature when Ageing Treatment of the temperature form carbon film in the forming face of metal pattern time and enforcement metal pattern is different.
But, as long as be no more than 600 DEG C oxidative degradation just can not occur owing to being formed on carbon film in the forming face of metal pattern, it therefore can the Temperature Setting by form carbon film in the forming face of metal pattern time be the temperature (570 DEG C) while implementing the Ageing Treatment of metal pattern.
In addition, although in the present embodiment, the heating-up temperature that tunicle is formed to the metal pattern 10 in operation S20 is made as 570 DEG C, is not limited thereto.
More than temperature owing to form carbon film 20 in the forming face of metal pattern 10 time is only required to be 400 DEG C (generating the temperature of nano-sized carbon class), and the temperature when Ageing Treatment of enforcement metal pattern 10 is only required to be 350 DEG C above, the heating-up temperature that therefore only tunicle need be formed to the metal pattern 10 in operation S20 is set as 400 DEG C above.
And as mentioned above, owing to likely can there is oxidative degradation in the time that carbon film 20 exceedes 600 DEG C, the heating-up temperature that therefore only tunicle need be formed to the metal pattern 10 in operation S20 is set as 600 DEG C below.
Therefore, be preferably, the heating-up temperature that tunicle forms the metal pattern 10 in operation S20 is set as 400～600 DEG C.
In addition, while forming carbon film in forming face in the temperature with identical with the Ageing Treatment of metal pattern and time and at metal pattern, even if the quantity delivered of the reacting gas of acetylene etc. is reduced to 20% left and right compared with existing value (quantity delivered while forming carbon film with the temperature of the Ageing Treatment lower than metal pattern), also can not cause larger impact to the quality of carbon film.Therefore, can be according to the condition of the Ageing Treatment of metal pattern, and the quantity delivered of reacting gas to acetylene etc. changes (minimizing).In the present embodiment, reduce ammonia (NH
3) service time, and make ammonia (NH
3) quantity delivered reduce (with reference to the hatching pattern part in Fig. 3 and Fig. 5) compared with existing value.In addition, to having reduced ammonia (NH
3) quantity delivered compensate, thereby increased nitrogen (N
2) quantity delivered.
In addition, can be according to the condition of the Ageing Treatment of metal pattern, cause compared with large effect and the heat time of metal pattern is changed with the quality to carbon film not.
So, by the degree the quality of carbon film 20 is not affected greatly, the temperature and the time that form when carbon film 20 are changed, and this temperature and time are made as to temperature and the identical value of time when metal pattern 10 is implemented to Ageing Treatment, thereby can form in operation S20 at tunicle, implement the formation of carbon film 20 and the Ageing Treatment of metal pattern 10 in the forming face of metal pattern 10 simultaneously.
Therefore, without the Ageing Treatment of implementing separately for metal pattern 10, thereby can reduce required time and the cost of manufacture of surface-treated metal mould 1.
In addition, although in the ordinary course of things, after the Ageing Treatment of having implemented for metal pattern, be implemented in the operation that forms carbon film in the forming face of this metal pattern, but due to the metal pattern having solidified by Ageing Treatment, form carbon film in the forming face of this metal pattern time, and again heated, therefore the effect of Ageing Treatment is by variation.But, due to according to the present invention, owing to forming in operation S20 at tunicle, implement the formation of carbon film 20 and the Ageing Treatment of metal pattern 10 in the forming face of metal pattern 10 simultaneously, therefore there will not be the poor situation of effect of Ageing Treatment, thereby metal pattern 10 can be set as to the hardness of expection.
As mentioned above, in the S1 of manufacturing process, by forming operation S20 through appearance operation S10 and tunicle successively, thereby produced surface-treated metal mould 1.
Although the forming face of produced metal pattern 10 presents coarse surface characteristic by multiple juts 1111 in appearance operation S10, but owing to forming in operation S20 and being formed with fine and close carbon film 20 in the forming face of metal pattern 10 at tunicle, therefore the forming face of surface-treated metal mould 1 presents fine and close surface characteristic.
All the time, thus by successively through making metal pattern shape be shaped roughing and make the fine finishining of surface smoothing produce metal pattern.Afterwards, by bead etc. and the surface of metal pattern is made as to male and fomale(M&F), and on this male and fomale(M&F), form the tunicle of carbon film etc.
But, in the present invention, due to by produce the metal pattern 10 of coarse surface characteristic in appearance operation S10 after, form in operation S20 and in the forming face of metal pattern 10, form fine and close carbon film 20 at tunicle, thereby produce surface-treated metal mould 1, therefore without the Surface Machining of implementing above-mentioned fine finishining and bead etc.
Therefore, can reduce required time and the cost of manufacture of surface-treated metal mould 1.
In addition, due in appearance operation S10, produce metal film 10 by utilizing laser that metal powders melt is solidified afterwards, therefore surface becomes activated state, newborn face becomes the state exposing.
Especially, due in the S1 of manufacturing process, after having implemented appearance operation S10, do not implementing under the condition of the Surface Machining such as above-mentioned this fine finishining and bead, implement tunicle and form operation S20, therefore, even form carbon film 20 in the forming face of metal pattern 10 time, in the forming face of metal pattern 10, can not be formed with oxide film thereon yet, thereby maintain the activated state of the forming face of metal pattern 10.
Thus, form in operation S20 at tunicle, can promote the forming face of metal pattern 10, with the reacting of the reacting gas of acetylene etc., thereby form at short notice firmly carbon film 20.
In addition, as casting parts involved in the present invention, except this metal pattern of surface-treated metal mould 1, can also adopt the slide unit of drift etc.
For example, adopt with parts drift in the casting as involved in the present invention, only need be at the upper formation of the outer peripheral face of this drift (sliding surface) tunicle identical with carbon film 20.
Industrial utilizability
The present invention can utilize in the casting parts and manufacture method thereof of metal pattern etc.
