Description

  The present invention relates to a component molding apparatus that forms a component shape at an end of a linear member.

For example, various linear components are used in which a metal component is formed at the end of a linear member such as a wire made of a stranded wire or a single wire or an elongated rod-shaped member. Examples of the part shape at the end of such a linear member include a stopper for locking the linear member to another part or preventing the linear member from coming off from a pipe member, and other parts. For example, a fitting part or a terminal part for holding the terminal can be used.
Conventionally, such an end part shape is often formed by fixing a metal part formed separately from the linear member to the linear member. As fixing methods, caulking, crimping, brazing, welding, adhesion, and the like are known.
As an example of forming the additional shape portion without using such a separately formed metal part, for example, Patent Document 1 discloses that at least one terminal is a distal end bending portion of an endoscope or an endoscope treatment tool. A terminal forming method of an operation wire that engages with the operation portion of the endoscope and advances and retreats according to an operation by the operation means of the endoscope and the treatment tool, and drives the distal end bending portion or the operation portion of the treatment tool, A method of forming an end of an operation wire for an endoscope is described, wherein the at least one terminal is formed by exposing the at least one terminal to an arc column and melting the terminal.

The component molding method of this embodiment is a method in which a wire installation process, a molding process, a mold transfer process, a mold separation process, a cutting process, and a component extraction process are performed in this order.
The wire installation process is a process of assembling the upper mold 17 and the lower mold 18 and inserting the wires 14 into the respective wire insertion holes 18b of the lower mold 18, and is performed outside the component molding apparatus 100.
That is, the lower mold 18 is arranged on a work table (not shown) where the lower part of the wire insertion hole 18 b is opened, and the lower surface 17 f of the upper mold 17 is arranged on the upper surface 18 e of the lower mold 18.

Next, the upper die 17 may be assembled on the lower die 18 in a state where the wires 14 are arranged in the same manner as described above.
When the wire 14 is inserted from above, the wire 14 may be prevented from coming off by bending or flattening a part of the wire 14 located in the cavity portion 18a.

The process from the molding process to the cutting process is performed using the component molding apparatus 100.
In the molding process, the hot metal receiving portions 17a in the mold 16, the runner portions 17b, and the cavity portions 18a in which the wires 14 are arranged are filled with a molten metal material, and the metal solidified body along these shapes. Is a step of forming.
In this step, first, the molding chamber 1A is opened to the atmosphere, and the mold 16 in an assembled state in which the wires 14 are arranged from a door (not shown) is placed on the mold setting portion 2 in the molding chamber 1A (see FIG. 4 (a)).
At this time, the horizontal position of the mold 16 is arranged such that the central axis of the sleeve 6A of the molten metal supply part 5 and the central axis of the hot water receiving part 17a are coaxial. The wire 14 that hangs down from the lower surface 18f hangs down through the slit 2a.
The mold 16 is oriented such that the side surfaces 17g and 18g face the entrance shutter 3a.
At this time, the extrusion arm 4a of the mold conveying mechanism 4 is contracted so that the extrusion arm 4a faces the side surface 17g, 18g opposite to the side surface of the mold 16 (this position is the initial position of the extrusion arm 4a). Called location).

Thus in parallel with the work of placing the die 16, the metallic material M ₀ is the material of the molded article 15 within the sleeve 6A, arranged between the lower end portion of the injection port 6a and the plunger 6B. In the present embodiment, the metallic material _{M 0} is ADC 12.
The amount of the metal material M _{0 is set to} an amount that can fill a large volume slightly larger than the volume of each cavity portion 18a and each runner portion 17b in the state of the molten metal M.
The height of the sleeve 6A, as shown in FIG. 4 (a), the metallic material M ₀ substantially at the center of the induction heating coil 7 keep the height to be maintained.

Next, with the door (not shown) of the molding chamber 1A and the entrance shutter 3a closed, the inside of the molding chamber 1A is vacuumed and then an inert gas is sealed.
For example, after the inside of the molding chamber 1A is made a vacuum atmosphere of 2 × 10 ⁻² Pa, nitrogen gas is sealed to make the inside of the molding chamber 1A an inert atmosphere of 50000 Pa.

Next, the induction heating coil 7 is energized to inductively heat the metal material M ₀ in the sleeve 6A.
When the molten metal M is formed by melting the metal material M _0, an induction magnetic field repelling the magnetic field of the induction heating coil 7 is formed in the molten metal M, so that the molten metal M is inductively suspended at the approximate center of the induction heating coil 7. It becomes a state to do.
When the molten metal M floats, as shown in FIG. 4B, the sleeve 6A is lowered and the sleeve 6A is inserted into the hot water receiving portion 17a. Since the sleeve 6A and the hot water receiving portion 17a are fitted so that they can be inserted, the hot water receiving portion 17a is closed from above by the sleeve 6A.
Further, each wire insertion hole 18 b of the mold 16 is closed by the inserted wire 14.
As a result, a molding space surrounded by the lower end surface of the sleeve 6A, the hot water receiving portion 17a, each runner portion 17b, and each cavity portion 18a is formed below the injection port 6a.

When the molten metal M is heated to 680 ° C., the energization of the induction heating coil 7 is stopped, the plunger 6B is lowered, pressure is applied to the molten metal M, and the molten metal M is injected from the injection port 6a (FIG. 5A). reference).
In this embodiment, a load of about 6 × 10 ⁴ N is applied to the plunger 6B and the molten metal M is pressed down.
As a result, the molten metal M injected from the injection port 6a flows into the molding space and is held in a pressurized state by the plunger 6B. The molten metal M is cooled and solidified by contact with the upper mold 17 and the lower mold 18, and a solidified metal m ₁ solidified along the shape of the molding space is formed in the mold 16.
When the metal solidified m ₁ is formed, as shown in FIG. 5 (b), at the same time raising the sleeve 6A and the plunger 6B, is detached by pulling out from the water receiving portion 17a.
This completes the molding process.

Next, a mold transfer process is performed. This step is a step of transferring the upper die 17 and the lower die 18 and the metal solid body m ₁ formed inside these from the molding chamber 1A to the cutting chamber 1B.
First, as shown in FIG. 6A, with the outlet shutter 3b closed, the pressure reducing valve that synchronizes the atmosphere of the molding chamber 1A and the pass box 3 is opened, and then the inlet shutter 3a of the pass box 3 is opened. . After opening the entrance shutter 3a, the pressure reducing valve is closed. Thus, since the exit shutter 3b is closed, the atmosphere of the molding chamber 1A does not affect the atmosphere of the cutting chamber 1B.
Next, the pushing arm 4 a of the mold transport mechanism 4 is extended to push the mold 16 to the inside of the pass box 3. The mold 16 moves in the horizontal direction on the mold installation unit 2 and the mold placement unit 3 c at the same height, and enters the pass box 3.
In the pass box 3, the wire 14 that hangs down from the lower mold 18 is accommodated in the linear member accommodation groove 3 d. For this reason, the wire 14 is curved without being plastically deformed in the linear member accommodating groove 3d, and is damaged by being pinched between the mold mounting portion 3c when the mold 16 is moved. There is no.

When the mold 16 moves to a position where the lock member 19 of the mold 16 faces the robot hand 8a of the lock member release mechanism 8 (see FIG. 5B), the mold transport mechanism 4 extends the push arm 4a. Stop and retract the push arm 4a back to the initial position.
Then, as shown in FIG. 6B, the entrance shutter 3a is closed.

  Next, each robot hand 8a of the lock member release mechanism 8 is extended toward the mold 16, and after holding each lock member 19 by each robot hand 8a, the lock member 19 is pulled out, and the lock member 19 is removed from the mold. Remove from 16. Thereby, the locked state of the mold 16 is released.

Next, as shown in FIG. 7A, in a state where the entrance shutter 3a is closed, the leak valve that synchronizes the atmosphere of the cutting chamber 1B and the pass box 3 is opened, and then the exit shutter 3b is opened. After opening the exit shutter 3b, the leak valve is closed. Thus, since the entrance shutter 3a is closed, the atmosphere in the cutting chamber 1B does not affect the atmosphere in the molding chamber 1A.
Then, the upper mold holding arm 11 and the lower mold moving arm 12 are extended, and the engagement protrusions 11a and 12a are inserted into the engagement holes 17c and 18c of the mold 16 and engaged.
Next, the upper mold holding arm 11 and the lower mold moving arm 12 are slightly raised so that the upper mold 17 and the lower mold 18 are kept in an assembled state, and the entire mold 16 is placed on the mold placing portion 3c. Float from. Then, the upper mold holding arm 11 and the lower mold moving arm 12 are contracted synchronously. Thereby, as shown in FIG.7 (b), the metal mold | die 16 is moved in the cutting chamber 1B. When the mold 16 comes out of the pass box 3, the exit shutter 3b is closed.
Thus, the mold transfer process is completed.

Next, a mold separation step is performed. In this process, as shown in FIG. 8, the upper mold 17 and the lower mold 18 are relatively moved by the mold moving unit 10 so as to be separated in the vertical direction, and the lower surface 17 f of the upper mold 17 and the upper surface 18 e of the lower mold 18. Is a step in which a gap D is provided between the upper mold 17 and the lower mold 18 to expose a part of the metal solid body m ₁ .
In the present embodiment, the lower mold moving arm 12 is moved vertically downward while the vertical position of the upper mold holding arm 11 is fixed. As a result, a portion of the metal solid body m ₁ formed by the cavity portion 18a is released from the wire insertion hole 18b in the vertical direction. Each wire 14, which is integrated in the metal solidified body m _1, since only is inserted into the wire insertion hole 18b, not hinder the movement of the lower mold moving arm 12.
In this way, a gap D is formed between the lower surface 17f and the upper surface 18e by the mold moving unit 10. The magnitude | size of the clearance gap D shall be a magnitude | size which is the extent which the rotary blade 9a mentioned later can approach in between. In the present embodiment, the gap D is about 4 mm.
This is the end of the mold separation process.

Next, a cutting process is performed. This step is a step of cutting the metal solid body m ₁ exposed between the gaps D to form three linear parts 13 from the metal solid body m ₁ .
In the present embodiment, as shown in FIG. 9 (a), the rotary blade 9a is rotated at 3000 rpm, it moved toward the metal solidified body _{m 1} of the clearance D by moving arm 9b, at a feed rate 3 mm / min Then, the solidified metal m ₁ exposed between the gaps D is cut (see FIG. 9B).
In the present embodiment, in order to make the length of the molded product portion 15 8 mm, the rotary blade 9 a is positioned at a position 2 mm away from the lower surface 17 f in a direction perpendicular to the central axis of the cylindrical portion formed by the cavity portion 18 a. Disconnect.
When the cutting is completed, the moving arm 9 b is contracted to move the rotary blade 9 a to the side of the mold 16.
Thus, the cutting process is completed.

Next, a component removal step is performed. This step is performed by moving the upper dies 17 and 18 to the outside of the component forming apparatus 100.
First, the cutting chamber 1B is opened to the atmosphere, and the upper mold 17 and the lower mold 18 each containing the metal solid body m ₁ are taken out from a door (not shown).
As shown in FIG. 10, in the lower mold 18, the three molded product parts 15 that are integrally formed with the wire 14 in the cavity part 18a and cut into a columnar shape are once released from the cavity part 18a. Are accommodated in the cavity 18a. For this reason, the molded product part 15 of the cavity part 18a is taken out upwards by pushing out the wire 14 from below to above or adsorbing the end face 15a.
Since the wire 14 is only inserted through the wire insertion hole 18 b, the molded product portion 15 is pulled out, and the wire 14 is pulled out from the wire insertion hole 18 b so that the linear component 13 can be taken out of the lower mold 18. In this embodiment, when the taken-out linear component 13 was measured, the outer diameter of the molded product part 15 was 2.9 mm, and the axial length of the molded product part 15 was 8 mm.
In addition, the metal solid body m ₁ included in the upper mold 17 is moved to the outside of the part forming apparatus 100 and then released from the mold, and is reused.
This completes the component removal process.

  In the present embodiment, the part taking-out process is described as an example in which the part taking-out process is manually performed outside the part forming apparatus 100, but the part taking-out process may be automatically taken out by a robot arm or the like. An automated take-out mechanism may be arranged in the component forming apparatus 100 and the component take-out step may be performed in the cutting chamber 1B after the cutting step is completed.

As described above, according to the component forming apparatus 100 of the present embodiment, the upper mold 17 and the lower mold 18 are assembled, and the metal solid body m ₁ is integrally formed on the plurality of wires 14. the upper mold 17 and lower mold 18 is separated from each other to expose the metal solidified body m _1, by cutting the metal solidified body m ₁ by cutting mechanism 9, a portion of the metal solidified m ₁ is an end of each wire 14 A plurality of linear parts 13 integrated in the part can be formed. For this reason, it is possible to efficiently form a component shape with good shape accuracy at the end of the wire 14.

In the present embodiment, since the lower mold 18 in which the cavity portion 18a is formed is not a split mold, the mold configuration is suitable when the roundness of the molded product portion 15 is required.
Further, since the cavity portion 18a and the wire insertion hole 18b are integrally formed in one mold member, the mold configuration is suitable when the coaxiality between the molded product portion 15 and the wire 14 is required. .

[Second Embodiment]
Next, a component molding apparatus according to a second embodiment of the present invention will be described.
FIG. 11 is a schematic perspective view showing an example of a linear part manufactured by the part molding apparatus according to the second embodiment of the present invention. FIG. 12 is a schematic exploded perspective view showing an example of a mold used in the component molding apparatus according to the second embodiment of the present invention. FIG. 13 is a schematic cross-sectional view of a mold used in a component molding apparatus according to the second embodiment of the present invention. FIGS. 14A and 14B are a schematic front view showing a schematic configuration of a component molding apparatus according to the second embodiment of the present invention, and a schematic perspective view of a mold moving unit.

  Before describing the configuration of the component molding apparatus 110 (see FIGS. 14A and 14B) of this embodiment, a linear component manufactured by the component molding apparatus 110 with reference to FIGS. 23 (parts) and a mold 26 used for manufacturing the linear part 23 will be described focusing on differences from the first embodiment.

As shown in FIG. 11, the linear part 23 is obtained by replacing the molded part 15 of the linear part 13 of the first embodiment with a molded part 25 having a different shape. The shape is not particularly limited as long as it can be molded with a split mold. For example, although it is good also as a shape similar to the molded article part 15, in this embodiment, it is set as the columnar body with a T-shaped cross section. Moreover, the end surface 25a on the opposite side to which the wire 14 in the molded product portion 25 is extended is formed by cutting.
Such a molded product part 25 can be used for the same application as the molded product part 15.
As the material of the molded product portion 15, an appropriate metal material that can be integrally formed with the wire 14 can be used. In this embodiment, as an example, the composition is Zr ₅₅ Cu ₃₀ Al ₁₀ Ni ₅ (atm%). The metal glass is used.

Metallic glass is an amorphous alloy in which the glass transition point is clearly observed when the temperature rises, and the temperature range of the supercooled liquid region (glass transition region) between the glass transition point and the crystallization temperature is An alloy with 20K or more.
Examples of the material of the metallic glass include a zirconium (Zr) based alloy, an iron (Fe) based alloy, a titanium (Ti) based alloy, a magnesium (Mg) based alloy, and the like.
Metallic glass melts a metal base material having a constant composition to form a melt of the base material alloy, and the molten metal is cooled below the critical transition rate of the base material alloy to below the glass transition point of the base material alloy. It is formed by making it amorphous by cooling.
In addition to the above composition, the Zr-based alloy may have a composition such as Zr ₆₀ Cu ₂₀ Al ₁₀ Ni ₁₀ (atm%), for example. Since these amorphous alloy materials are mainly composed of Zr, they are excellent in mold transferability and can be easily formed into complex shapes. Moreover, since these are amorphous alloys, they are excellent in chemical resistance.
For example, an amorphous alloy material mainly composed of titanium (Ti) is also suitable. For example, Ti ₄₀ Zr ₁₀ Cu ₃₆ Pd ₁₄ can be mentioned. This material is particularly excellent in biocompatibility, and is a material suitable for an endoscope part used in direct contact with the human body.

As shown in FIGS. 12 and 13, the mold 26 is composed of a single upper mold 27 (first mold) having a rectangular parallelepiped outer shape and mold members 29 and 30 which are connected in a horizontal direction so as to be divided into two. The lower mold 18 (second mold) is a three-part split mold that is detachably stacked in the vertical direction and assembled in a rectangular parallelepiped shape as a whole.

Thereby, the relative positions of the upper mold 27 and the lower mold 28 are fixed in the overlapping direction.

The upper die 27 includes runner portions 27b instead of the runner portions 17b of the upper die 17 of the first embodiment.
As shown in FIG. 12, the shape of each runner portion 27b opens in a circular shape at the bottom of the hot water receiving portion 17a, and the cross section is reduced toward the lower surface 17f. The lower surface 17f has the same shape as the cross section of the molded product portion 25. It is formed as a hole to be a T-shaped opening 27j. These openings 27j constitute a plurality of discharge ports for discharging the molten metal received by the hot water receiving portion 17a to the lower mold 28 side.

The mold members 29 and 30 are rectangular parallelepiped block-shaped members having shapes symmetrical to each other, and upper surfaces 29e and 30e that form a plane that overlaps the upper surface 28e of the upper mold 27, and lower surfaces 29f and 30f that respectively oppose them. It has.
The mold members 29 and 30 are detachably connected to each other in the horizontal direction on the mold dividing surfaces 29h and 30h, which are one side surfaces.
A lock member insertion hole 18d for inserting the tip end portion of the lock member 19 is provided on each side surface in the horizontal direction adjacent to the mold dividing surface 29h (30h) of the mold member 29 (30). For this reason, as shown in FIG. 12, the relative positions of the mold members 29 and 30 in the horizontal direction are fixed by the two lock members 19 at the time of connection.
Mold split surface 29h, the 30h, the upper surface 29e, 30e and the lower surface 29f, in the thickness direction between 30f, 3 one through hole consisting of the cavity portion _{S 1} and the wire insertion hole _{H 1} Metropolitan is formed.

Cavity S ₁ is a hole having a T-shaped cross section which forms the shape of the molded article 25, the mold split surfaces 29h, L-shaped cross section in the thickness direction from the top surface 29e to the lower surface 29f intermediate It is formed by a cavity forming surface 29a extending toward the portion and a cavity forming surface 30a provided symmetrically with the mold dividing surface 30h.
Each cavity _{S 1} has the upper mold 27 upper surface 29e, when superimposed on 30e, is provided in a position connected with three openings 27j of the upper die 17.
Hole depth of the cavity S ₁ has a length more than the depth of the molded article 25. Therefore, so that the shape of the molded article 25 by cutting the metal solidified body that is solidified along the shape of the cavity S ₁ is formed.

Wire insertion groove 29 b, 30b is a bottom respectively from the hole bottom of the cavity portion _{S 1} 29f, extends through to 30f. Therefore, the lower surface 29f, by inserting the wire 14 through the wire insertion hole H ₁ from 30f side, and to be able to place the end of the wire 14 into the cavity portion S _1.

In the present embodiment, the hole depth of the cavity portion _{S 1} is, 10 mm, inner diameter of the wire insertion hole _{H 1} is set to 1 mm.
The material of the lower mold 28 having the cavity portion S ₁ is a material having a thermal conductivity that can cool the metallic glass having the composition Zr ₅₅ Cu ₃₀ Al ₁₀ Ni _{5 at} a cooling rate higher than the critical cooling rate. Any suitable material can be used.
As the material of the upper mold 27, an appropriate mold material having a lower thermal conductivity than that of the lower mold 28 can be adopted.
In the present embodiment, as an example, SUS304 is used for the material of the upper mold 27 and oxygen-free copper is used for the material of the lower mold 28.
Thus, by making the thermal conductivity of the material of the upper mold 27 smaller than the thermal conductivity of the material of the lower mold 28, the molten metal is not rapidly cooled by the hot water receiving portion 17a and the runner portion 27b. It is injected into the cavity S ₁ in the liquid state. Therefore, the molten metal is satisfactorily filled into the cavity portion S _1.

  Further, the side surface 29g (30g) of the mold member 29 (30) is provided with an engagement hole portion 29c (30c) formed of a square hole having a rectangular cross section extending in the horizontal direction.

Next, a schematic configuration excluding the mold 26 of the component molding apparatus 110 of the present embodiment will be described with reference to FIGS. 14 (a) and 14 (b).
The component molding apparatus 110 includes a mold movement unit 20 instead of the mold movement unit 10 of the component molding apparatus 100 of the first embodiment, and includes a lock member release mechanism 8A and a component collection unit 31. is there. Hereinafter, a description will be given centering on differences from the first embodiment.

In the same way as the mold moving unit 10 in the first embodiment, the mold moving unit 20 moves the mold 26 from which the lock member 19 has been pulled out in the pass box 3 into the cutting chamber 1B while maintaining its assembled state. The upper mold 27 and the lower mold 28 are separated from each other in the vertical direction, and a part of the solidified metal formed inside the mold 26 is exposed between the upper mold 27 and the lower mold 28. Is.
However, the mold moving unit 20 can separate the mold members 29 and 30 from the metal solidified body by separating the mold members 29 and 30 of the lower mold 28 separated from the upper mold 27 in the horizontal direction. Is different from the mold moving unit 10.

Therefore, as shown in FIG. 14B, the mold moving unit 20 includes an upper mold holding arm 21 and lower mold moving arms 22A and 22B provided on the side wall of the cutting chamber 1B facing the outlet opening 3f. Is provided.
The upper mold holding arm 21 is engaged with the upper mold 27 mounted on the mold mounting portion 3c at the tip, instead of the engagement protrusion 11a of the upper mold holding arm 11 in the first embodiment. An engagement protrusion 21a that engages with the joint hole portion 27c is provided.
The lower mold moving arms 22A and 22B are formed of an extendable arm that moves forward and backward in the horizontal direction from the side wall of the cutting chamber 1B below the upper mold holding arm 21 toward the outlet opening 3f, and extends along the side wall of the cutting chamber 1B. They are arranged side by side in the horizontal direction.
The lower mold moving arm 22A is disposed at a position facing the engagement hole 29c of the mold member 29 of the lower mold 28 placed on the mold placement section 3c, and has an engagement hole 29c at the tip. An engagement protrusion 22a to be engaged is provided.
The lower mold moving arm 22B is disposed at a position facing the engagement hole 30c of the mold member 30 of the lower mold 28 placed on the mold placement section 3c, and has an engagement hole 30c at the tip. An engagement protrusion 22b to be engaged is provided.
Further, the base end portions of the lower mold moving arms 22A and 22B are supported so as to be movable in the vertical direction and in the horizontal direction along the side wall portion of the cutting chamber 1B.

  The lock member release mechanism 8A removes the two lock members 19 connecting the mold members 29 and 30 in the pass box 3, and is similar to the lock member release mechanism 8 as shown in FIG. Includes a robot hand 8a. However, unlike the lock member release mechanism 8, the robot hand 8 a is provided on the mold placing portion 3 c so as to face the moving direction of the mold 26, and each robot hand 8 a is set in a direction orthogonal to the moving direction of the mold 26. It can be moved forward and backward. For this reason, after the mold 26 is moved to a fixed position on the mold placing portion 3c, the robot hand 8a is advanced, and the lock member 19 can be pulled out and removed.

  The parts collection unit 31 is a collection container for collecting the linear parts 23 formed by being cut in the cutting chamber 1B and taking them out of the cutting chamber 1B. The component collection unit 31 is provided at the bottom of the cutting chamber 1B below the outlet shutter 3b and the mold moving unit 10 so as to be able to be taken in and out of the cutting chamber 1B.

Next, the operation of the component molding apparatus 110 will be described focusing on differences from the first embodiment.
15 (a), (b), (c), (d), (e), and (f) are schematic operation explanatory views of the component forming apparatus according to the second embodiment of the present invention.

The component molding method of this embodiment is a method in which a wire installation process, a molding process, a mold transfer process, a mold separation process, a cutting process, and a component extraction process are performed in this order.
Wire installation step assembles the upper die 27 and lower die 28, the respective wire insertion holes H ₁ of the lower die 28 is a step for inserting the wire 14, is performed outside the part-forming apparatus 110. The details are the same as in the first embodiment except that the lower mold 28 is connected, and the operation of connecting the mold members 29 and 30 by the two lock members 19 is performed.

The process from the molding process to the cutting process is performed using the component molding apparatus 110.
Molding step, a water receiving portion 17a of the mold 26, and the runner portion 17b, the wire 14 is filled with a molten metal material and a respective cavity portion S ₁ arranged, the metal solidifies along these shapes This is a step of forming the body m ₂ .
This step is different in that the metal material M ₀ is a material constituting the Zr-based alloy.
In the same manner as in the first embodiment, the molten metal M is formed and floated, and when the molten metal M is heated to 1000 ° C., the induction heating coil 7 is de-energized and the plunger 6B is lowered to move the molten metal M to the molten metal M. Inject from the injection port 6a under pressure.
As a result, the molten metal M injected from the injection port 6a flows into the molding space of the mold 26 and is held in a pressurized state by the plunger 6B. The molten metal M is solidified in the mold 26 along the shape of the molding space, and a metal solid body m ₂ is formed.
At this time, since the material of the lower mold 28 is oxygen-free copper, the molten metal M is rapidly cooled at a cooling rate equal to or higher than the critical cooling rate. Therefore, the metal solidified m ₂ is amorphized solidified as glassy.
This completes the molding process.

Next, a mold transfer process is performed. This step is a step of transferring the upper mold 27 and the lower mold 28 and the metal solid body m ₂ formed inside them from the molding chamber 1A to the cutting chamber 1B.
In this process, the mold 26 moved to the pass box 3 is used for the upper mold 27 and the mold member 29, the upper mold 27 and the mold 27 by using the two lock member releasing mechanisms 8 and the two lock member releasing mechanisms 8A. The point which removes the lock member 19 in total which connects the die member 30, the die member 29, and the die member 30 differs from the said 1st Embodiment.
Further, when the mold 26 after the lock member 19 is removed is moved to the cutting chamber 1B, the upper mold 27 is held by the upper mold holding arm 21 of the mold moving unit 20, and the lower mold moving arms 22A and 22B are respectively used. The point which hold | maintains the mold members 29 and 30 differs from the said 1st Embodiment.
That is, the upper mold holding arm 21 and the lower mold moving arms 22A, 22B are extended, and the engaging protrusions 21a, 22a, 22b are inserted into the engaging holes 27c, 29c, 30c of the mold 26, respectively. Combine.
Next, the upper mold holding arm 21 and the lower mold moving arms 22A and 22B are slightly raised so that the upper mold 27 and the mold members 29 and 30 are kept assembled with each other, and the entire mold 26 is moved. Then, it floats on the mold mounting part 3c. Then, the upper mold holding arm 21 and the lower mold moving arms 22A and 22B are contracted synchronously. Thereby, as shown to Fig.14 (a), the metal mold | die 26 is moved in the cutting chamber 1B. When the mold 26 comes out of the pass box 3, the exit shutter 3b is closed.
FIG. 15A is a side view as viewed from C in FIG. 14A schematically showing the state at this time.
Thus, the mold transfer process is completed.

Next, a mold separation step is performed. In this step, the upper mold 27 and the lower mold 28 are relatively moved by the mold moving unit 20 so as to be separated in the vertical direction, and the lower surface 27f of the upper mold 27 and the upper surfaces 29e and 30e, which are the upper surfaces of the lower mold 28, are moved. In this step, a gap D is provided between the upper mold 27 and the lower mold 28 so that a part of the metal solid body m ₂ is exposed.
This step is performed in the same manner as in the first embodiment except that the lower mold moving arms 22A and 22B are moved vertically downward in synchronization. Thereby, as shown in FIG. 15B, the mold members 29 and 30 are lowered and separated from the upper mold 27, and the metal solid body m ₂ is exposed between the gaps D.
This is the end of the mold separation process.

Next, a cutting process is performed. This step is a step of cutting the metal solid body m ₂ exposed between the gaps D to form three linear parts 23 from the metal solid body m ₂ .
In the present embodiment, as shown in FIG. 15 (c), the rotary blade 9a is rotated at 3000 rpm, it moved toward the metal solidified _{m 2} in the space D by moving arm 9b, at a feed rate 2 mm / min The solidified metal m ₂ exposed between the gaps D is cut.
When the cutting is completed, the moving arm 9b is contracted to move the rotary blade 9a to the side of the mold 26 (see FIG. 15D).
Thus, the cutting process is completed.

Next, a component removal step is performed.
In this step, first, the lower mold moving arms 22A and 22B are moved in the horizontal direction away from each other. Thus, as shown in FIG. 15 (e), the molded product portion 25 formed by cutting from metal solidified body m ₂ is being released from the mold members 29 and 30, such that shown in FIG. 15 (f) Then, it falls into the component collection unit 31 on the lower side.
Next, the part collection unit 31 in which the linear parts 23 have dropped is taken out of the cutting chamber 1B.
Thus, in the present embodiment, the cut linear component 23 can be taken out of the cutting chamber 1B without opening the cutting chamber 1B to the atmosphere.
Further, the metal solid body m ₂ contained in the upper mold 27 is moved from the unillustrated unloading port provided in the cutting chamber 1B to the outside of the part forming apparatus 110, and then released from the mold and reused.
This completes the component removal process.

For the molded article 25 of the linear part 23 thus formed by, was subjected to the shape measurement, the much less molding shrinkage as compared with the first embodiment, faithfully the shape of the cavity S ₁ It was confirmed that it was transcribed. As described above, in the molding by the metal glass, since the molding shrinkage is small, it is difficult to release from the cavity forming surface of the mold as compared with the material having a large molding shrinkage. In the present embodiment, the lower mold moving arm 22A, Since the mold members 29 and 30 are moved in the horizontal direction by 22B and the cavity forming surfaces 29a and 30a are separated from the molded product portion 25 in the horizontal direction, the molded product portion 25 can be easily released.
Moreover, when the amorphous property of the molded product part 25 was evaluated with an X-ray diffraction (XRD) apparatus, it was confirmed that all of the three molded product parts 25 were amorphous.

  Here, the result of having experimented about the combination of the material of the metal mold | die 26 in the case of shape | molding the molded article part 25 using metal glass is demonstrated. Table 1 shows the material of the mold used in the experiment, and the evaluation results for evaluating the filling property and the amorphous property of the molded product portion 25 formed thereby.

In Table 1, in Experimental Examples A1, A2, and A3, the material of the lower die 28 is oxygen-free copper (Cu: thermal conductivity 400 W / (m · K)), and the material of the upper die 27 is Cu, stainless steel, respectively. In an experimental example in the case of steel SUS304 (thermal conductivity 15 W / (m · K)), Ni-Cr heat resistant alloy HA230 (trade name: manufactured by Mitsubishi Materials Corporation) (thermal conductivity 9 W / (m · K)) is there.
Note that the combination of materials in Experimental Example A2 matches the material conditions in the second embodiment described above.
In Experimental Examples B1, B2, and B3, the material of the lower die 28 was hot die steel SKD61 (thermal conductivity 30 W / (m · K)), and the material of the upper die 27 was Cu, SUS304, and HA230, respectively. It is an example of an experiment.
Experimental examples C1, C2, and C3 are experimental examples when the material of the lower mold 28 is SUS304 and the material of the upper mold 27 is Cu, SUS304, and HA230, respectively.
Experimental examples D1 and D2 are experimental examples in which the material of the lower mold 28 is HA230 and the material of the upper mold 27 is Cu and SUS304, respectively.

Regarding the filling property, the case where the shape of the cavity was transferred satisfactorily by visual observation and there was no problem in quality was indicated by ◯, and the case where voids were present as internal defects was indicated by Δ.
As for the amorphous property, ◯ indicates that the amorphous property is confirmed to be good by the XRD apparatus, and X indicates that the crystallization site is confirmed in a part of the molded part 25 by the XRD device. did.

Regarding filling properties, Experimental Examples A1, B1, C1, C2, D1, and D2 were evaluated as Δ. In common, the thermal conductivity of the upper mold 27 is larger than the thermal conductivity of the lower mold 28.
On the other hand, in the experimental examples A2, A3, B2, B3, and C3 in which the thermal conductivity of the upper mold 27 is smaller than that of the lower mold 28, the evaluation was good.
This is because if the thermal conductivity of the upper die 27 is not less than the thermal conductivity of the lower mold 28, since a part of the molten metal M tends to solidify at the receiving portion 17a and the runner portion 27b water, filled in the cavity portion S ₁ This is considered to be because the molten metal M is reduced or becomes an obstacle to filling.

Regarding amorphousness, Experimental Examples D1 and D2 having a thermal conductivity of 9 W / (m · K) were evaluated as “x”, and the others were evaluated as “good”.
That is, it was found that the amorphousness is irrelevant to the material of the upper mold 27 and is good when the thermal conductivity of the lower mold 28 is 15 W / (m · K) or more.

  From the evaluation results as described above, when the molded part 25 is formed from a material that becomes a metal glass, the thermal conductivity of the lower mold 28 is set to 15 W / (m · K) or more, and the thermal conductivity of the upper mold 27 is set. It is understood that a material smaller than the thermal conductivity of the lower mold 28 is preferably used.

  As described above, according to the component molding apparatus 110, the linear component 23 having the molded product portion 25 using the metal glass at the distal end portion of the wire 14 can be manufactured with high accuracy and efficiency.

It is an arm member, and a grip portion 41a for gripping the metal solidified body is provided at the tip portion.

Next, the operation of the component molding apparatus 120 will be described focusing on differences from the first and second embodiments.
20 (a), (b), (c), (d), (e), and (f) are schematic operation explanatory views of the component forming apparatus according to the third embodiment of the present invention.

The component molding method of this embodiment is a method in which a wire installation process, a molding process, a mold transfer process, a mold separation process, a cutting process, and a component extraction process are performed in this order.
Wire installation step assembles the upper die 47 and lower die 48, the respective wire insertion holes of H ₂ lower mold 48 is a step for inserting the wire 44, is performed outside the part-forming apparatus 120. The details are that the upper die 47 (lower die 48) is assembled except that the operation of connecting the die members 51, 52, 53, 54 (61, 62, 63, 64) by the four lock members 19 is performed. This is the same as in the first embodiment.

The process from the molding process to the cutting process is performed using the component molding apparatus 120.
Molding step, a water receiving portion 47a of the mold 46, and the runner portion 47b, by filling a molten metal material to the wire 44 and the second cavity portion T ₂ arranged, along these shapes This is a step of forming the metal solid body m ₃ .
This step is performed in the same manner as in the second embodiment.

Next, a mold transfer process is performed. In this step, the upper die 47, lower die 48, and a metal solidified m ₃ formed these internal, a step of transferring the cutting chamber 1B from the molding chamber 1A.
In this step, all the lock members 19 inserted in the mold 46 are removed from the mold 46 moved to the pass box 3 by using the two lock member release mechanisms 8 and the two lock member release mechanisms 8A. This is different from the first embodiment.
Further, when the mold 46 after removing the lock member 19 is moved to the cutting chamber 1B, the intermediate arm 40b of the mold moving unit 40 is inserted into the moving arm insertion holes P ₁ and P ₂ of the mold 46, and The point that the die 46 is held in the assembled state by inserting the tip arm portion 40c of the die moving portion 40 into the moving arm tip portion insertion holes Q ₁ and Q ₂ of the die 46 is the same as the first embodiment. Different.

Next, each mold moving part 40 is slightly raised, and the entire mold 46 is lifted from the mold placing part 3c with the upper mold 47 and the lower mold 48 maintained in an assembled state. Then, each mold moving unit 40 is contracted in synchronization. As a result, the mold 46 is moved into the cutting chamber 1B. When the mold 46 comes out of the pass box 3, the exit shutter 3b is closed.
FIG. 20A is a side view schematically showing the state at this time. At this time, the metal solid body holding portion 41 is arranged on the side of the mold 46.
Thus, the mold transfer process is completed.

Next, a mold separation step is performed. In this process, the upper mold 47 and the lower mold 48 are moved relative to each other by the mold moving unit 40 so as to be separated in the vertical direction, and a gap is provided between the lower surface 47f of the upper mold 47 and the upper surface 48e of the lower mold 48. In this step, a part of the metal solid body m ₃ is exposed between the upper mold 47 and the lower mold 48.
In this embodiment, as shown in FIG. 20B, the positions of the two mold moving parts 40 that hold the lower mold 48 are fixed, and the mold moving part 40 that holds the mold members 52 and 51. And the mold moving part 40 holding the mold members 53 and 54 are separated from each other in the horizontal direction, and the mold members 52 and 51 and the mold members 53 and 54 are separated from the metal solid body m _3. After that, it is moved above the metal solid body m ₃ .
Thus, the metal solidified m _3, all except the portion located in the cavity portion S ₃ is exposed on the upper surface 48e of the lower die 48.
This is the end of the mold separation process.

Next, a cutting process is performed. This step is a step of cutting the metal solid body m ₃ exposed on the lower mold 48 to form _three linear parts 43 from the metal solid body m ₃ .
In the present embodiment, as shown in FIG. 20 (c), the metal solid body m ₃ is gripped from the side by the metal solid body holding portion 41. Next, the rotary blade 9a is rotated at 3000 rpm, moved toward the metal solidified _{m 3} by moving arm 9b, at a feed rate 2 mm / min, the metal solidified _{m 3} exposed above the upper surface 48e first cutting a cylindrical-shaped portion formed by the cavity portion T _1.
When the cutting is completed, the moving arm 9b is contracted to move the rotary blade 9a to the side of the lower die 48 (see FIG. 20D).
Thus, the cutting process is completed.
In this step, when the metal solid body m ₃ is cut, the portion formed by the first cavity portion T ₁ having a smaller diameter than the runner portion 47 a and the molded product main body 45 a is cut, so that the cutting time can be reduced. .

Next, a component removal step is performed.
In this step, first, the mold moving unit 40 holding the mold members 62 and 61 and the mold moving unit 40 holding the mold members 63 and 64 are moved in the horizontal direction away from each other. Thus, as shown in FIG. 20 (e), the molded product portion 45 formed by cutting from metal solidified _{m 3} is, is die member 62 and 61, and the mold members 63 and 64 release, As shown in FIG. 20 (f), it falls into the component collection unit 31 on the lower side.
Next, the part collection part 31 in which these linear parts 43 have dropped is taken out of the cutting chamber 1B.
As described above, in this embodiment, similarly to the second embodiment, the cut linear part 43 can be taken out of the cutting chamber 1B without opening the cutting chamber 1B to the atmosphere.
Further, the metal solid body m ₃ held by the metal solid body holding part 41 moves to the outside of the component forming apparatus 120 from a carry-out port (not shown) provided in the cutting chamber 1B.
In addition, the mold members 52 and 51, the mold members 53 and 54, the mold members 62 and 61, and the mold members 63 and 64 held by the four mold moving units 40 are collected and reused. To serve.
This completes the component removal process.

When the shape of the molded product portion 45 of the linear part 43 formed in this way was measured, the shapes of the first cavity portion T ₁ and the second cavity portion T ₂ were the same as in the _second embodiment. Was confirmed to be faithfully transferred. Moreover, when the amorphous property of the molded product part 45 was evaluated by an X-ray diffraction (XRD) apparatus, it was confirmed that all of the three molded product parts 45 were amorphous.

As described above, according to the component molding apparatus 120, the linear component 43 having the molded product portion 45 using the metal glass at the distal end portion of the wire 44 can be manufactured with high accuracy and efficiency.
In the present embodiment, further, the mold moving unit 40 of the 2 groups, by dividing the upper mold 47, in order to release the metal solidified m _3, and the release operations from the upper mold 47, the metal solidified m ₃ can be performed at the same time, the upper mold 47 can be quickly reused after the cutting process is completed.

Moreover, in this embodiment, since the metal mold | die 46 is made into the split body of 8 body structure, even when the molded product part 45 has a complicated shape, mold release becomes easy.
For example, as shown in FIGS. 21A and 21B, the metal members m ₃ are moved by moving the mold members 53 and 54 or the mold members 63 and 64 in the horizontal direction (the front side in the drawing). When separating from the molded part 45, the mold member 53 (63) may be moved in parallel with the mold member 54 (64) to be slightly separated.
In order to perform such a separation operation, as shown in FIG. 21B, the tip arm portion 40c is extended to the tip side, and the tip arm portion 40c allows the moving arm tip portion insertion hole Q ₁ (Q ₂ ) to move. What is necessary is just to press a hole bottom part.
By combining such a separating operation, the mold member 53 (63) to the metal solidified m ₃ and the molded product 45 can facilitate the detachment of the mold member 54 (64).

  Further, if such an axial separation operation in the mold moving unit 40 is used, the runner part and the cavity part straddle the mold members 51, 52, 53, 54 and the mold members 61, 62, 63, 64. Can be easily released even if the shape of the runner part and the cavity part is complicated.

  In the description of each of the above embodiments, an example in which three cavities are provided in one mold has been described. However, this is only an example, and a cavity and a runner connected to the cavity As long as there are two or more, any number may be provided.

  In the description of each of the above embodiments, the example in which the first mold and the second mold maintain the assembled state by the lock member 19 in the molding process has been described. However, the lock member 19 is not used. It is good also as a structure. For example, a clamp mechanism that clamps the first mold and the second mold in an assembled state is provided on the mold installation unit 2, and when moving to the pass box 3, the clamp mechanism is released and transferred. May be. In this case, the work of removing the lock member 19 in the pass box 3 can be omitted. Further, the lock member member release mechanisms 8, 8A, etc. can be deleted.

  In the description of each of the above embodiments, an example in which the molding process in the molding chamber 1A and the cutting process in the cutting chamber 1B are sequentially performed using a set of molds has been described. Since the molding step and the cutting step can be performed independently of each other, the cutting step is performed in parallel while performing the molding step with one mold using two or more molds.
