Description

  The present invention relates to a molding apparatus for integrally molding a molded part on a linear member.

For example, various mechanical parts in which a metal part (hereinafter referred to as an additional part) is added to a part of a linear member such as a wire made of a stranded wire or a single wire or an elongated rod-like member are used. Examples of such additional parts include a stopper for locking the linear member to another part or preventing the linear member from coming off from a pipe member, and a fitting for holding the linear member on the other part. Examples include parts and terminal parts.
Conventionally, such an additional component is often formed by fixing a metal component formed separately from the linear member to the linear member. As fixing methods, caulking, crimping, brazing, welding, adhesion, and the like are known.
It is also conceivable to arrange a linear member in a mold for forming the shape of the additional part and integrally mold the additional part around the linear member.
For example, although the target component shape is different, as a technique for integrally forming a molded product on a linear member, Patent Document 1 has a fine hole for forming the fine hole of an optical connector ferrule with high accuracy. A method and apparatus for manufacturing an injection molded article is described.
In this manufacturing method and apparatus, in order to form a pore, a wire is inserted and stretched from the wire insertion hole into the cavity of the fixed mold, and in this state, injection molding is performed, and demolding, wire movement, and molding are performed. By repeating, a large number of injection molded products having the outer shape of the ferrule for optical connectors are formed on the wire. And after cutting this wire between injection molded products, a wire is pulled out from an injection molded product. Thereby, the injection molded product is detached from the wire, and the ferrule for optical connector is manufactured.

FIG. 6B is an operation explanatory diagram of the linear member holding portion. FIGS. 7A and 7B are a side view illustrating the configuration of the mold detachment portion of the molding apparatus according to the first embodiment of the present invention, and an operation explanatory diagram thereof.
In addition, since each figure is a schematic diagram, the dimension and shape are exaggerated (the following drawings are also the same).

Before describing the configuration of the molding apparatus 100 (see FIG. 3) of the present embodiment, it is manufactured by the molding apparatus 100 with reference to FIGS. 1 (a), 2 (a), 2 (b), and (c). An example of the linear component 16 and the mold 10 used for manufacturing the linear component 16 will be described.
As shown in FIG. 1A, the linear component 16 has a single metal wire W that is a linear member, and a plurality of metal additional component portions Q (molded components) having a length of the wire W. They are provided apart in the direction. The pitch at which the additional component part Q is provided is set to a pitch at which the molds 10 can be arranged separately along the length direction of the wire W. Although only two additional component parts Q are drawn in FIG. 1A, any number of additional component parts Q may be provided.
The type of the wire W may be a stranded wire or a single wire, but in the following, an example in the case of a stranded wire will be described. The material of the wire W is not particularly limited. For example, a stainless wire or a copper wire can be employed.
The shape of the additional component part Q is not particularly limited as long as it can be formed by molding.
Hereinafter, as an example of the additional component portion Q, an example in which a cylindrical member having a diameter larger than the outer diameter of the wire W is provided coaxially with the central axis of the wire W will be described. Such an additional part Q is used, for example, as a positioning part, a holding part, a locking part, a retaining part, a fitting part, etc. of the linear part 16 when the linear part 16 is assembled to another part. Is possible.
Further, when energizing the wire W, it can be used as an electrical connection terminal, a contact point, or the like.

As the material of the additional part Q, an appropriate metal material that can be integrally formed with the wire W can be adopted. Hereinafter, as an example, an explanation will be given of an example of an amorphous alloy known as a so-called metallic glass.
Metallic glass is an amorphous alloy in which the glass transition point is clearly observed when the temperature is raised, and the temperature range of the supercooled liquid region between the glass transition point and the crystallization temperature is 20K or more. That is.
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.
Specifically, for example, a composition (atm%) _is able examples of such _{Zr 55 Cu 30 Al 10 Ni 5} , Zr 60 Cu 20 Al 10 Ni 10. 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 nickel (Ni) is added, these are excellent also 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.

The product form of the linear part 16 may be a product form including all of the plurality of molded additional part parts Q. However, a large number of additional part parts Q are formed on a long wire W, and the product is formed on a reel or the like. After collecting as a wound semi-finished product, the wire W and the additional part Q may be cut and processed into a final product shape.
For example, the linear component 16A shown in FIG. 1B is cut at both ends of the additional component portion Q by cutting the wires W before and after one additional component portion Q in the linear component 16 at the wire cutting surface 16a. The wires W ₁ and W ₂ are processed into a shape that extends. The lengths of the wires W ₁ and W ₂ may be the same length or different lengths.
In addition, the linear component 16B shown in FIG. 1C similarly cuts the wire W at the wire cutting surface 16a at one end of the additional component portion Q of the linear component 16, and starts from one end portion of the additional component portion Q. cut wire W ₃ is obtained by machining to form extends.
Linear parts 16B, specifically, for example, when the wire W ₂ is an operation wire used for bending operation of the endoscope, the additional component part as a stopper for fixing the wire W ₃ into the endoscope Q can be used.
Moreover, the linear part 16C shown in FIG. 1 (d), similarly, the additional component Q of the linear part 16 is cut at the cut surface 16b of the center and an additional component part Q _1, additional component portion Q is obtained by machining to cut across the additional component unit Q ₁ is marked with the form of a wire W ₄ together.

As shown in FIGS. 2 (a), 2 (b), and 2 (c), the mold 10 has a rectangular parallelepiped lower mold 10a and an upper mold 10b that are superposed on each other and provided on one side surface. It is connected by 10h so that opening and closing is possible.
The lower die 10a, the center of the die matching surface A ₁ of the upper mold 10b are superposed, molded surface 10c which forms the shape of the lower half of the outer diameter of the additional component unit Q is provided. In the present embodiment, the shape of the molding surface 10c is a groove shape in which a semicircular cross section is extended by the length of the additional component portion Q corresponding to the additional component portion Q being cylindrical.
Wire insertion grooves 10e having a semicircular cross section coaxial with the central axis of the semicircular cross section of the molding surface 10c are connected to both ends in the extending direction of the molding surface 10c, and each penetrates the side surface of the lower mold 10a. . The groove diameter of the wire insertion groove 10 e is set to an inner diameter slightly larger than the outer diameter of the wire W.
The upper mold 10b, the center of the die matching surface A ₂ to be overlaid with the lower mold 10a, mold surface 10d that form the shape of the upper half of the outer diameter of the additional component unit Q is provided. Further, wire insertion grooves 10f having the same shape as the wire insertion grooves 10e are provided at both ends in the extending direction of the molding surface 10d. The molding surface 10d and the wire insertion groove 10f are provided at positions facing the molding surface 10c and the wire insertion groove 10e, respectively, when the upper mold 10b is superimposed on the lower mold 10a.
As a result, when the lower mold 10a and the upper mold 10b are closed and the mold mating surfaces A ₁ and A ₂ are in close contact with each other, the linear component 16 is formed inside the mold 10 by the molding surfaces 10c and 10d. A cylindrical cavity S for forming the additional part Q is formed. Further, a wire insertion hole H having a circular cross section through which the wire W can be inserted is formed on the central axis of the cavity S by the wire insertion grooves 10e and 10f.
Between the back surface side upper surface A ₃ of the upper die 10b of the die matching surface A ₂ and the molding surface 10d, the molten metal inlet 10g is a circular hole for injecting the molten metal into the cavity S is, the upper die 10b is provided penetrating in the vertical direction when the lower mold 10a is overlaid.

As shown in FIG. 3, the molding apparatus 100 of the present embodiment is a manufacturing apparatus that sequentially and integrally molds a plurality of additional component parts Q at different positions on the wire W using a plurality of molds 10. It consists of a plurality of apparatus parts provided.

Shutters 2 and 3 for opening and closing the respective openings are provided in the partition wall 1C in the vicinity of the mold inlet 1a and the mold outlet 1b.
By closing these shutters 2 and 3, the molding chamber 1 </ b> A and the mold cooling chamber 1 </ b> B become independent spaces, and the circulation of the atmosphere between them is suppressed. For this reason, heat transfer between the molding chamber 1A and the mold cooling chamber 1B is also suppressed, and the temperature conditions in each chamber can be adjusted independently.
The atmosphere in the molding chamber 1A may be an inert atmosphere depending on the type of metal material used for molding. In this case, the mold introduction port 1a and the mold discharge port 1b are on the molding chamber 1A side and the mold cooling chamber 1B side so that the mixing of the atmosphere between the molding chamber 1A and the mold cooling chamber 1B can be further suppressed. It is good also as a structure which provides a shutter in each of these, and accommodates the metal mold | die 10 temporarily among them.

The molding chamber 1A is provided with a delivery reel 6 on one end side in the longitudinal direction (left side in the figure in FIG. 3) and a take-up reel 7 on the other end side in the longitudinal direction (right side in the figure in FIG. 3). A conveyor 4 is extended between the take-up reels 7 along the longitudinal direction of the molding chamber 1A.
Around the conveyor 4, a mold closing cylinder 8, a component molding unit 20, a mold discharge cylinder 12, and a mold opening cylinder from one end side to the other end side in the longitudinal direction of the molding chamber 1 </ b> A. 13 are arranged in this order.

In this embodiment, the height of the stretched wire W from the upper surface of the transport conveyor 4 is set to a height slightly exceeding the thickness of the lower mold 10a (see FIG. 4A).

The conveyor 4 moves the mold 10 moved from the mold inlet 1a into the molding chamber 1A in the same direction as the direction of conveyance of the wire W in accordance with the intermittent conveyance of the wire W by the take-up reel 7. It constitutes the first mold moving part.
In this embodiment, the width of the conveyor 4 is set to be equal to or greater than the width in the short direction of the mold 10 in the closed state, and the longitudinal direction of the mold 10 in the closed state can be arranged along the moving direction. It is like that. For this reason, as shown in FIG. 3, when the mold 10 is opened (see the mold 10 </ b> B), at least a part of the upper mold 10 b protrudes to the side of the conveyor 4.
In the conveyor 4, the position of the end facing the mold inlet 1 a constitutes a mold mounting position P ₀ where the mold 10 is mounted when the conveyor 4 is stopped.
The mold 10 mounted at the mold mounting position P ₀ is moved at the molding position P ₁ of the intermediate part of the transport conveyor 4 by the intermittent movement of the transport conveyor 4 and at the end of the transport conveyor 4 on the take-up reel 7 side. which is so sequentially stopped in the mold disengaged position P ₂ is a position opposed to the mold outlet 1b there. The pitch at which these mold mounting position P ₀ , molding position P ₁ (first stop position), and mold release position P ₂ (second stop position) are provided is the additional part portion Q in the linear part 16. In consideration of the slack of the wire W, the pitch is slightly shorter than the pitch at which the additional component part Q is formed.

Cylinder moving part 14, as shown in FIG. 7 (a), the cylinder 13 opens the mold, the state in which the piston 13a is closed is moved into the mold disengaged position P ₂ of the die 10 of the upper mold 10b It is a member that supports the upper end at a height at which it can be pressed and supports the mold discharge port 1b and the conveyor 4 so as to be able to advance and retreat.
Therefore, when opening the mold 10, the cylinder moving unit 14 moves the mold opening cylinder 13 to the side of the mold 10, and after opening the mold 10 as shown in FIG. 3. The mold opening cylinder 13 can be retracted from between the mold discharge port 1 b and the mold 10.

The mold cooling chamber 1B is discharged from the molding chamber 1A by the mold discharge cylinder 12 and moved to the mold cooling chamber 1B, and the opened mold 10 is moved to the mold mounting position P _{0 of the} conveyor 4. The temperature of the room is adjusted so that the temperature is lower than that of the molding chamber 1A.
The mold cooling chamber 1 </ b> B is provided with a conveyor 5 that can move in a state where the mold 10 that returns to the end of the conveyor 4 on the side of the delivery reel 6 is opened. The conveyance conveyor 5 has a length at which both ends are opposed to the mold discharge port 1b and the mold introduction port 1a, and is provided in parallel with the conveyance conveyor 4 in this embodiment. Thereby, the both ends of the conveyor 5 are extended to the positions facing the mold discharge port 1b and the mold introduction port 1a, respectively. At both ends, the portions facing the mold discharge port 1b and the mold introduction port 1a are respectively a mold recovery position P ₃ for recovering the mold 10 discharged from the molding chamber 1A into the mold cooling chamber 1B. When constitute a gold mold 10 moves, and the mold inlet position P ₄ to move the molding chamber 1A through a die inlet port 1a by the transport conveyor 5.
Conveyor 5 is adapted to move the die 10 in the open state which has been placed in a mold recovery position P ₃ (the mold 10B see FIG. 3) to the mold introduction position P _4.
In the mold cooling chamber 1B, a mold introduction cylinder 15 is provided at a position facing the mold introduction port 1a with the conveyor 5 interposed therebetween.
The mold introduction cylinder 15 includes a piston 15 a that pushes the mold 10 moved to the mold introduction position P ₄ to the mold mounting position P ₀ on the transport conveyor 4. Therefore, it is possible to move the gold mold 10 moved to the mold inlet position P _4, the mold mounting position P ₀ extruded from a die inlet 1a of opened shutter 2.
The configuration of the mold introduction cylinder 15 may be the same as that of the mold discharge cylinder 12.

Next, the operation of the molding apparatus 100 will be described.
FIGS. 8A, 8B, and 8C are operation explanatory views of the component forming portion of the forming apparatus according to the first embodiment of the present invention.

First, as shown in FIG. 3, the wire W is stretched between the delivery reel 6 and the take-up reel 7. Further, the mold introducing position P ₄ of the mold cooling chamber 1B, set in a state where the mold is opened 10 which has been cooled to a temperature of the molten metal M of the material to be metallic glass can be cooled at a critical cooling rate or cooling rate (See mold 10A in FIG. 3).
At this time, both the wire W and the conveyors 4 and 5 are stopped. Also, both shutters 2 and 3 are closed.

Then open the shutter 2, to extend the piston 15a of the mold introducing cylinder 15, the sides of the mold 10 (10A) is pressed to move the mold 10 (10A) to the mold mounting position _{P 0} . At this time, the die 10 which is moved to the mold mounting position P ₀ is a state where the longitudinal direction of the lower die 10a resting on the conveyor 4 in a posture along the conveyance direction of the conveyor 4, the wire insertion groove 10e is The upper mold 10b is positioned on the mold closing cylinder 8 while being positioned in parallel and directly below the stretched wire W (see FIG. 4A).
In the present embodiment, the mold 10 slides on the floor surface 1c and moves onto the conveyor 4 at the same height as the floor surface 1c. When providing a level | step difference between the floor surface 1c and the conveyance conveyor 4, for example, the conveyance path in which the conveyance roller etc. was installed is on the floor surface 1c between the conveyance conveyors 4 and 5 of the both sides of the metal mold | die inlet 1a. Prepare it.
When the mold 10 moves into the molding chamber 1A, the shutter 2 is closed and the mold inlet 1a is closed.

Next, as shown in FIG. 4B, the mold closing cylinder 8 is extended to push up the upper mold 10b. As a result, the upper mold 10b rotates about the hinge 10h, and the upper mold 10b. Moves onto the lower mold 10a, and the mold 10 is closed.
At this time, the wire W is pushed down by the wire insertion groove 10f of the upper mold 10b and is sandwiched between the wire insertion groove 10e. As a result, the wire is inserted into the cavity S formed by the wire insertion hole H formed by the wire insertion grooves 10e and 10f and the molding surfaces 10c and 10d.

  For this reason, the mold introduction cylinder 15 and the mold closing cylinder 8 are arranged with the mold 10 on the transport conveyor 4 which is the first mold moving section, and the delivery reel is placed in the cavity S of the mold 10. 6 constitutes a mold preparation unit for arranging the wire W sent out from 6.

Next, delivery reel 6, by driving the take-up reel 7, and the conveyor 4 at the same time, moves toward the wire is W, the a mold 10 which is closed at the mold mounting position P ₀ to the molding position P ₁ .
When the die 10 reaches the molding position P _1, and stops the delivery reel 6, a take-up reel 7, and the conveyor 4 at the same time. Here, as shown in FIG. 5, the molding position P ₁ is a position where the injection nozzle 23 c of the molten metal injection portion 23 can advance and retract from the molten metal injection port 10 g of the mold 10.
Then extending the clamp piston 24a of the clamping cylinder 24 on the lower side, the upper surface _{A 3} of the upper mold 10b of a mold 10 stops at the molding position _{P 1} is pressed from above, the lower mold 10a and upper mold 10b The mold matching surfaces A ₁ and A ₂ are clamped in a state where they are securely adhered.
On the other hand, the molten metal injection unit 23, the die 10 until it reaches the molding position P _1, was charged with the amount of metal material required for forming the additional component unit Q into the injection cylinder 23a, the induction heating A high-frequency current is passed through the coil 23d, and this metal material is induction-heated to form the molten metal M.

Next, as shown in FIG. 8A, the wires W extended from the mold 10 to the upstream side and the downstream side in the conveying direction by the clamp arms 9A and 9B are slightly moved from the side surface of the mold 10, respectively. It is clamped from above and below at a distant position.
Then, the clamp arms 9A and 9B are brought close to the mold 10 along the direction in which the wires W are stretched, and the twists of the wires W in the cavity S sandwiched between the clamp arms 9A and 9B are twisted back in the respective directions. The side grip 9c and the upper grip 9d are moved to rotate the wire W around its central axis.
At this time, since the outer shape of the wire W sandwiched between the wire insertion grooves 10e and 10f is restricted to the inner diameter range of the wire insertion grooves 10e and 10f, as shown in FIG. In S, the twist of the wire W returns to expand the diameter. Thereby, in the cavity S, the wire fraying portion R having a gap between the single wires constituting the wire W is formed.
In addition, by such rotation of the wire W, the outer wire W sandwiched between the clamp arms 9A and 9B is twisted in a direction in which the twist is tight, but the length of the wire W is longer than the length in the cavity S. Since it is long, distortion caused by torsion is small and does not hinder rotation.

Next, when the molten metal M reaches a moldable temperature, the injection nozzle 23c is lowered and inserted into the molten metal injection port 10g. And the injection piston 23b by the induction heating coil 23d is lowered, and the molten metal M is injected from the injection nozzle 23c.
Thereby, the molten metal M is injected into the cavity S of the mold 10.

The molten metal M injected into the cavity S is filled into the cavity S, rapidly cooled by heat conduction from the parts 10c and 10d and the wire W, and cooled at a cooling rate equal to or higher than the critical cooling rate. Thereby, the molten metal M is solidified along the shape of the cavity S, and a metal glass solidified body m (see FIG. 8C) is formed.
Since the molten metal M of the present embodiment is made of a material that becomes a metallic glass, the mold transferability is good. Accordingly, not only the molding surfaces 10c and 10d are in close contact with each other, but also the unevenness on the surface of the wire W and the gaps between the single wires of the wire frayed portion R are well filled and in close contact with each surface. Solidify.
For this reason, in the center part of the cavity S, the molten metal M is solidified in the state where the wire frayed part R enters. Therefore, compared with the case where the frayed portion R is not formed and the molten metal M is solidified only on the outer surface of the wire W, the pulling strength of the wire W after solidification can be improved.

Note that the molten metal M tries to enter the gap between the wire W and the wire insertion hole H, but since these gaps are extremely narrow, the heat capacity of the molten metal M to be entered is small. For this reason, the molten metal M to be entered immediately solidifies in the vicinity from the cavity S and hardly enters.
Therefore, it does not leak out of the mold 10 from the wire insertion hole H. Further, even if the molten metal M enters, it solidifies along the wire insertion grooves 10e and 10d, so it is solidified into a bar shape slightly thicker than the outer diameter of the wire W, and burrs that need to be removed are not formed.

When the injection of the molten metal M is completed, the injection nozzle 23c is pulled up and pulled out from the molten metal injection port 10g. And it waits for the molten metal M in the cavity S to become below the glass transition temperature and to be cooled to such an extent that the shape of the solidified material does not change due to the impact of movement.
Then, as shown in FIG. 8C, the clamp arms 9A and 9B are moved away from the mold 10 along the extending direction of the wires W, and the wires W in the cavity S sandwiched between the clamp arms 9A and 9B The lower gripping part 9c and the upper gripping part 9d are moved in the twisting direction to rotate the wire W around its central axis.
By this operation, the twist of the wire W in the metal glass solidified body m in which the molten metal M is solidified is not retwisted, but the change in twist generated in the wire W outside the cavity S is returned to the initial state.

Next, the clamp piston 24a is raised and the clamp of the mold 10 is released.
The delivery reel 6, by driving the take-up reel 7, and the conveyor 4 at the same time, a wire is W, the a mold 10 in which the metal vitrified m is formed in the cavity S in the mold disengagement position P ₂ Move towards.
When the die 10 reaches the mold disengaged position P _2, to stop the delivery reel 6, a take-up reel 7, and the conveyor 4 at the same time.
And the position of the wire W with respect to the metal mold | die 10 is fixed on both sides of the wire W extended from the side surface of the metal mold | die 10 by the clamp arms 9C and 9D.

In die-off position P _2, until the mold 10 is moved, the cylinder moving part 14, keep moving the cylinder 13 to open the mold in a position facing the die ejector cylinder 12.
As shown in FIG. 7A, when the mold 10 is moved to the mold separation position P < _b > ₂ , the piston 13 a of the mold opening cylinder 13 is extended toward the mold 10.
When the piston 13a comes into contact with the side surface of the upper mold 10b, a rotational moment around the hinge 10h acts on the upper mold 10b to rotate the upper mold 10b, and as shown in FIG. The mold 10 is opened.
At this time, since the wire W is held at a position sandwiching the mold 10 by clamp arms 9C and 9D (not shown in FIG. 7B), the position with respect to the lower mold 10a is fixed. Therefore, the additional part Q is released from the molding surface 10d with the rotation of the upper mold 10b, the additional part Q is left on the lower mold 10a, and only the upper mold 10b moves.
Thereby, the metal mold | die 10 is opened and the upper mold | type 10b will be in the state arrange | positioned on the floor surface 1c of the side of the conveyance conveyor 4 (refer metal mold | die 10B of FIG. 3).

When the mold 10 is opened, the cylinder moving part 14 moves the mold opening cylinder 13 from the position facing the mold 10 to the take-up reel 7 side and retracts it.
Further, the clamp arms 9C and 9D are moved up, and the wire W with the additional part portion Q held between the clamp arms 9C and 9D is moved above the lower mold 10a to separate the additional part portion Q from the molding surface 10c. Mold. At this time, the clamp arms 9 </ b> C and 9 </ b> D move the wire W to a position where the lower end portion of the additional component portion Q is above the die-matching surface of the lower die 10 a.

Next, the shutter 3 is opened, the mold discharge port 1b is opened, the piston 12a of the mold discharge cylinder 12 is extended, the side surface of the upper mold 10b of the mold 10 is pressed, and the mold 10 is moved to the mold. moving the mold recovery position P ₃ on the conveyor 5 in the cooling chamber 1B. At this time, on the conveyor 5, the upper mold 10 b remains facing the molding chamber 1 </ b> A, and the center of gravity of the opened mold 10 is on the conveyor 5 (the mold in FIG. 3). 10C).
In this embodiment, the mold 10 slides on the floor surface 1c and moves from the conveyor 4 at the same height as the floor 1c onto the conveyor 5 via the floor 1c. When providing a level | step difference between the floor surface 1c and the conveyance conveyors 4 and 5, for example, the conveyance path in which the conveyance roller etc. were installed is made into the floor between the conveyance conveyors 4 and 5 of the both sides of the metal mold | die discharge port 1b. It is provided on the surface 1c.

When the mold 10 of the mold disengagement position P ₂ is moved onto the conveyor 5 mold cooling chamber 1B, the side opposite to the die discharge opening 1b in conveyor 4 to contract the die discharge cylinder 12 Evacuate. Further, the shutter 3 is closed.
In this way, the additional part Q is formed on the wire W and released from the mold 10.
Die 10 which is moved into the mold recovery position P ₃ while being cooled by the mold cooling chamber 1B, are moved by conveyor 5 to molds introduction position P _4, waits as the mold 10 reusable .

As described above, the mold discharge cylinder 12 and the conveyor 5 collect the mold 10 separated from the additional part Q at the mold separation part, and the collected mold 10 is a mold preparation part. A second mold moving part is configured to move to the vicinity of the mold introduction cylinder 15.
The mold cooling chamber 1B is provided on the moving path of the mold 10 recovered by the second mold moving unit, and constitutes a recovery mold cooling unit that cools the recovered mold 10. .

  As described above, the operation has been described by paying attention to one additional part portion Q formed on the wire W. However, in the molding apparatus 100, at least three molds 10 are circulated in the molding chamber 1A and the mold cooling chamber 1B. Thus, a plurality of additional component parts Q are formed on the wire W. Hereinafter, an operation for another mold 10 performed in parallel with the above operation will be briefly described.

Molding position P ₁ in the mold 10 moves the (referred to as mold 10 preceding) After delivery reel 6, a take-up reel 7, and the conveyor 4 is stopped, by opening the shutter 2, in the same manner as described above moves other half 10 a (referred to as mold 10 to trailing) to the mold mounting position P _0. Then, while the molding in position P ₁ in a mold 10 in which the preceding is being performed, the closed mold 10 for trailing the die mounting position P _0.
When the preceding die 10 is moved to the mold withdrawal position P _2, the die 10 to the line post at the same time as this movement is moved to the molding position P _1.
Then, a mold withdrawal of the mold 10 which precedes the mold disengaged position P _2, and parallel with this, the molding perform using a mold 10 for trailing the molding position P _1. Further, in parallel with this, the third mold 10 is moved to the mold mounting position P ₀ .
Then, the preceding mold 10 that has been separated from the mold is positioned opposite to the mold introduction port 1a by the conveyor 5 while the delivery reel 6, the take-up reel 7 and the conveyor 4 are moved next. Move to.
Thus, according to the molding apparatus 100, by recycling the three molds 10, on the wire W, or pitch corresponding to the distance between the molding position P ₁ and the mold removed position P _2, additional The parts Q are sequentially formed, and the linear part 16 is formed.

  In the above description, the example in which there are three molds 10 has been described. However, the number of molds 10 may be three or more as long as the conveyor 5 can move by placing a plurality of molds 10 thereon. . In this case, since the time for one mold 10 to stay in the mold cooling chamber 1B can be made longer, it can be reused while moving on the conveyor 5 even if it takes time to cool the mold 10. Can be cooled to any temperature.

The wire W on which the additional part portion Q is formed is wound around the take-up reel 7 by the rotation of the take-up reel 7.
In this way, when the additional part Q is formed on the wire W prepared in advance and the wire W cannot be sent out from the delivery reel 6, the molding apparatus 100 is stopped and the atmosphere in the molding chamber 1A is changed to the atmospheric atmosphere. The linear part 16 taken up by the take-up reel 7 is recovered by returning to step S2.
The linear component 16 may be supplied as a product wound on the take-up reel 7, or may be appropriately processed and supplied as a product such as the linear components 16A, 16B, 16C. Also good.

  As described above, in the molding apparatus 100, the mold preparation unit sequentially molds the additional component parts Q at different positions on the continuous wire W by sequentially arranging the plurality of molds 10 on the conveyor 4. It has become.

  According to the molding apparatus 100 of the present embodiment, the wire W and the plurality of molds 10 are moved in the molding chamber 1A, and the linear component 16 in which the additional component portion Q is integrated with the wire W is molded. For this purpose, a mold preparation step for disposing the wire W in the cavity S of the mold 10, a molding step for injecting the molten metal M into the cavity S of the mold 10 to form the solidified metal m, and metal glass Since the mold detachment step of detaching the mold 10 from the solidified body m can be performed in parallel at a plurality of molds and a plurality of positions, the linear component 16 can be efficiently manufactured.

[Modification]
Next, a modification of this embodiment will be described.
FIG. 9 is a schematic plan view showing the overall configuration of a molding apparatus according to a modification of the first embodiment of the present invention.

Molding apparatus 110 of the present modification, intermediate the molding position P ₁ and the mold removed position P ₂ of the molding apparatus 100 of the first embodiment, the cooling position P _C of the mold cooling portion 30 is provided set, the mold 10 has been moved to the molding position P ₁ is that so as to stop the cooling position P _C by the movement of the next. Hereinafter, a description will be given centering on differences from the first embodiment.

Mold cooling section 30 is not particularly limited as long as it is configured to be cooled mold 10 which has moved to the cooling position P _C by conveyor 4. For example, the molten metal M is injected around the mold 10 and an air cooling mechanism that cools the mold 10 by flowing a gas at a temperature lower than that of the mold 10 whose temperature has risen, or the molten metal M is injected by circulating a refrigerant inside. A configuration such as a contact cooling mechanism in which a cooling plate having a temperature lower than that of the mold 10 whose temperature has risen can be brought into contact with the surface of the mold 10 can be employed.
When a contact cooling mechanism is adopted, the cooling plate may be pressed from the vertical direction of the mold 10 and brought into contact with the mold 10 to serve as a presser for the mold 10.

According to the molding apparatus 110 of this modified example, after injecting the molten metal M in the molding position P _1, and moved to a cooling position P _C, quenching the molten metal M in mold cooling portion 30. For this reason, even if the heat capacity of the mold 10 is small and only the molten metal M is injected, the molten metal M is not cooled below the glass transition temperature and is in a supercooled liquid state. The glass can be cooled to a temperature not higher than the glass transition temperature at a cooling rate not lower than the critical cooling rate. For this reason, size reduction of the metal mold | die 10 can be achieved.
Further, there is a need to shorten the pitch of the additional component portion Q is formed, even if not cooled to a temperature at which separation of the mold is possible during movement from the molding position P ₁ to the mold withdrawal position P _2, it can be cooled until the mold detachable temperature in the cooling position P _C. For this reason, it is not necessary to stop the mold 10 at the molding position P ₁ until the temperature at which the mold 10 can be moved to the mold separation position P _2. Therefore, the stop time at the molding position P ₁ is shortened and the molding efficiency is improved. can do.

[Second Embodiment]
Next, the shaping | molding apparatus of the 2nd Embodiment of this invention is demonstrated.

The molding apparatus 120 according to the present embodiment forms the product shape of the linear part 16 </ b> A in the chamber 1.
For this reason, instead of the take-up reel 7, a traction moving unit 40 (linear member transport unit) is provided, and a cutter unit 44 and a linear component storage unit 43 are further added.
Further, the molding apparatus 120, moving the part-forming portion 20 and the molding position P ₁ of the molding device 100 of the first embodiment, the position corresponding to the mold mounting position P ₀ of the molding apparatus 100.
For this reason, the mold 10 moved onto the conveyor 4 by the mold introduction cylinder 15 is closed by the mold closing cylinder 8 below the component molding unit 20, and the mold 10 is moved by the conveyor 4. The injection nozzle 23c can be inserted into the molten metal injection port 10g of the upper mold 10b in a closed state.
The molding apparatus 120 includes a mold cooling chamber 1D instead of the mold cooling chamber 1B.
Hereinafter, a description will be given centering on differences from the first embodiment.

The traction moving unit 40 includes a clamp arm 9E having the same configuration as that of the clamp arm 9C of the first embodiment, and a close position of the clamp arm 9E adjacent to the clamp arm 9D along the wire W extending direction. A clamp arm moving unit 41 that reciprocates linearly from C _n to a remote position C _f that is further away from the clamp arm 9D.
The moving distance between the proximity position C _n and the remote position C _f of the clamp arm moving unit 41 is set to a distance corresponding to the entire length of the linear part 16A.
The configuration of the clamp arm moving unit 41 is not particularly limited as long as the clamp arm 9E can be reciprocated linearly along the direction in which the wire W is stretched. For example, a configuration such as a ball screw feeding mechanism or a linear motor can be employed.

Cutter unit 44 is slightly remote position C _f closer position than the close position C _n of the clamp arm 9E, it is to cut the wire W stretched clamp arm 9D, by 9E. The specific configuration of the cutter unit 44 may be a configuration in which the wire W is sandwiched and cut, or a configuration in which the rotary blade is advanced and retracted to the wire W and cut.

The linear component storage unit 43 is a box-shaped member having a longer opening width than the length of the linear component 16A in order to store the linear component 16A in which the wire W is cut by the cutter unit 44, and the wire W is stretched over the linear component storage unit 43. On the lower side, the opening in the longitudinal direction is arranged along the direction in which the wire W is stretched.
Further, the linear component storage portion 43 can carry out the stored linear component 16 </ b> A to the outside of the chamber 1 through an unillustrated outlet provided in the chamber 1.

  The cutter part 44 and the linear part storage part 43 constitute a cutting and collecting part that cuts and collects the wire W on which the additional part part Q is formed.

The mold cooling chamber 1D is replaced with a cooling means for lowering the atmospheric temperature in the mold cooling chamber 1B of the first embodiment, while the mold 10 is cooled while the mold discharge port 1b is in contact with the mold introduction port. The cooling moving part 5A which moves to 1a side is provided.
The cooling moving unit 5 </ b> A cools the mold 10 by heat conduction caused by contact between the mounting unit and the mold 10, in which the mounting unit itself on which the mold 10 is mounted is cooled. .
For example, this cooling plate is provided with a conveyor mechanism that drives a metal conveyor cooled with an appropriate refrigerant and kept at a low temperature, and a conveyance path composed of a metal cooling plate on which the mold 10 can slide. It is possible to employ a mechanism in which the mold 10 is arranged on the top and the mold 10 is moved in contact with the cooling plate using a moving means such as a movable arm or a cylinder.

Next, the operation of the molding apparatus 120 will be described with a focus on differences from the first embodiment.
In the molding apparatus 120, first, sending the end of the wire W fed from the reel 6 is gripped by the clamp arm 9E, feed conveyor 4 between the clamp arm 9E disposed adjacent position C _n the reel 6 The wire W is stretched over.
Next, the opened mold 10 is moved onto the conveyor 4 by the mold introduction cylinder 15 in the same manner as in the first embodiment.
Then, the mold 10 is closed by the mold closing cylinder 8. As a result, the stretched wire W is sandwiched between the wire insertion grooves 10e and 10f.
In this state, the molding by the component molding unit 20 is performed without moving the conveyor 4 and the wire W.

Melt M is injected into the cavity S, If a state capable of moving the mold 10, the feeding of the feed reel 6, and the movement of by the clamp arm movement section 41 to the remote location C _f side of the clamp arm 9E, conveyor 4 is simultaneously performed. Then, when the clamp arm 9D reaches a remote location C _f, the delivery reel 6 stops the clamp arm movement section 41, and the conveyor 4.
Thus, the mold 10 is moved to the mold withdrawal position P _2.

In die-off position P _2, in the same manner as in the first embodiment, and holds the wire W clamp arm 9C, the 9D, by operating the cylinder 13 to open the mold, the state in which the mold is opened 10 (See FIG. 10) Further, the clamp arms 9C and 9D are moved slightly upward to disengage the additional part Q from the lower mold 10a.
Next, the wire W stretched between the clamp arms 9D and 9E is cut by the cutter unit 44. Then, the clamp of the clamp arm 9E is released.
As a result, the cut wire W falls into the linear component storage unit 43. However, the additional part Q is not formed on the cut wire W at the beginning of molding. From the second cutting, as shown in FIG. 10, the wire W in which the additional part portion Q is formed is cut, and the cut part is a linear part 16A.

Next, the clamp arm 9E is moved to the proximity position C _n by the clamp arm moving unit 41, the end of the wire W clamped by the clamp arm 9D is gripped by the clamp arm 9E, and the cut end of the wire W is clamped Match with the holding height by arm 9D.
In parallel with this, in the same manner as in the first embodiment, the die ejector cylinder 12 to move the die 10 to the die recovery position P ₃ of the mold cooling chamber 1D. In this embodiment, the mold recovery position P ₃ is a position facing the die discharge opening 1b on the cooling moving portion 5A.

Once the mold 10 is discharged from the mold disengaged position P _2, to release the clamp of the clamp arm 9C, 9D. Thereby, the clamp arm moving part 41 is ready to move the wire W.

The mold 10 moved to the mold cooling chamber 1D is disposed on the cooling moving unit 5A and cooled by contact with the cooling moving unit 5A. Then, while being moved from the mold recovery position P ₃ to the mold inlet position P ₄ is a position opposed to the mold inlet 1a on the cooling moving unit 5A, is cooled to a reusable mold temperature .

In this way, in the molding apparatus 120, the mold 10 is moved and circulated in the order of the mold introduction position P ₄ , the molding position P ₁ , the mold removal position P ₂ , and the mold collection position P ₃ , and the molding position is reached. a forming step in P _1, and a mold withdrawal process in the mold disengagement position P ₂ can be performed in parallel. For this reason, the additional component part Q can be efficiently shape | molded on the wire W with a fixed pitch similarly to the said 1st Embodiment.
Furthermore, in this embodiment, since the step of cutting the wire W is performed in the mold detachment step, the processing up to the processing of the linear component 16A that is a product form in which the wire W is cut can be performed in the molding apparatus 120. .

In the molding apparatus 130, the mold closing cylinder 8, the component molding unit 20, and the clamp arms 9 </ b> A and 9 </ b> B are arranged around the mold 10 in the same positional relationship as in the second embodiment. . Further, the mold opening cylinder 13 is disposed on the side opposite to the mold closing cylinder 8 of the mold 10. However, since the mold opening cylinder 13 does not need to be retracted from the side of the mold 10, the positions in the horizontal direction and the height direction are fixed on the floor surface 1c by the cylinder holding portion 14A.

According to the present embodiment, the mold 10 is closed by the mold closing cylinder 8 while the wire W is stopped.
Next, in the same manner as in the first embodiment, the component molding unit 20 molds the additional component unit Q by injecting the molten metal M into the cavity S of the closed mold 10.

Next, similarly to the clamp arms 9C and 9D of the first embodiment, the clamp arms 9A and 9B are raised, and the additional part Q is released from the molding surface 10c of the lower mold 10a.

In this way, when the release of the additional component part Q is completed, the delivery reel 6 and the take-up reel 7 are driven to move the wire W by a length corresponding to the pitch of the additional part part Q.
Then, the above operation is repeated. Thereby, the linear component 16 in which the plurality of additional component portions Q are formed on the wire W is formed and wound around the take-up reel 7.

The molding apparatus 130 of the present embodiment is an example in the case where a plurality of additional component parts Q are formed on the wire W without moving the mold 10.
According to the molding apparatus 130, since it is the structure opened and closed by the upper and lower sides of the wire W which spanned the metal mold | die 10, compared with the case where the wire W is penetrated from opening of a metal mold | die, working efficiency can be improved.
Moreover, since the clamp arms 9A and 9B are provided on the upstream side and the downstream side in the conveyance direction of the wire W, the position of the wire W with respect to the mold 10 can be adjusted or fixed. For this reason, arrangement | positioning with respect to the metal mold | die 10 of the wire W and the mold release of the additional component part Q become easy.
Further, when the wire W is a stranded wire, the wire W can be molded with the wire frayed portion R formed in the cavity S as in the first embodiment, so that the fixing strength of the wire W is improved. be able to.
