The pressing rod 47 extends from the end part 46 toward the terminal 4 and the bus bar 3, which are mounted on the jig 13 of the step-in 33 for holding. A longitudinal direction of the pressing rod 47 is in parallel to a longitudinal direction of the above mentioned terminal 4. When the rod 45 of the cylinder 42 for pressing is contracted, the terminal 4 and the bus bar 3, which are mounted on the jig 13 in the step-in 33 for holding, are arranged in pressing possible position through the hole.
When the rod 45 of the cylinder 42 for the pressing is contracted, and the pressing rod 47 of the pressing member 43 is passed into the hole, the above member pressing part 32 presses the terminal 4 and the bus bar 3 mounted on the jig 13 of the step-in 33 for holding. The component pressing part 32 presses the bus bar 3 and the terminal 4 toward the fixing die 22 from the jig 13 into the step-in 33 for holding. These bus bar 3 and terminal 4 are mounted on the cavity of the fixing die 22.
As described below, the above mentioned molded article production apparatus 5 forms the box body 2, which the bus bar 3 and the terminal 4 are buried in, into an insert forming. The transfer unit 6 is provided with the jig 13 which the bus bar and the terminal 4 are not mounted on. The bus bar 3 is mounted on the jig 13 by the bus bar attaching apparatus 7, and the terminal 4 is mounted on the jig 13 by the terminal mounting apparatus 8. Thereafter, the jig 13, which the bus bar 3 and the terminal 4 are mounted on, is carried near the transfer apparatus 12 by the second transfer unit 9.
The transfer apparatus 12 covers the step-in 33 for holding of the component attaching part 30 in the attaching part 28 with the jig 13 on the second transfer unit 9. The rod 36 of the cylinder 34 for holding of the component attaching part 30 in the attaching part 28 is extended by the transfer apparatus 12. The transfer apparatus 12 mounts the jig 13 into the step-in 33 for holding, that is, the jig 13 is mounted on the component attaching part 30. Furthermore, the transfer apparatus 12 extends the rod of the cylinder 17 for sliding in the member for preventing 15 of the jig 13, and sandwiches the bus bar 3 and the terminal 4 between the main body 14 and the top plate 16, and holds these bus bar 3 and terminal 4 in the jig 13.
As shown in FIG. 3, the transfer apparatus 12 positions the attaching part 28 between the die 22 and 23, which are separated from each other, by driving the robot arm 27. At this time, the component attaching part 30 is opposite to the fixing die 22, and the molded article attaching part 31 is opposite to the moving die 23. The molded box body 2 is mounted on the moving die 23.
As shown in FIG. 4, the rod of the chuck cylinder 37, namely, both the chuck members 38, in condition that the chuck members are separated from each other, the robot arm 27 brings the molded article attaching part 31 of the attaching part 28 close to the moving die 23, and positions the box body 2 between a pair of the chuck members 38. Thereafter, as shown in FIG. 5, the rod of the chuck cylinder 37, that is, each chuck members 38 are approached to each other, and the box body 2 is sandwiched between a pair of the chuck members 38.
As shown in FIG. 6, the transfer apparatus 12 drives the robot arm 27, and moves the component attaching part 30 of the attaching part 28 close to the fixing die 22 in condition that the box body 2 is sandwiched between the chuck members 38. After, as shown in FIG. 7, the transfer apparatus 12 reduces the rod of the cylinder 17 for sliding in the jig 13, and stops sandwiching the bus bar 3 and the terminal 4 between the main body 14 and the top plate 16.
Thereafter, the transfer apparatus 12 reduces the rod 45 of the cylinder 42 for pressing in the member pressing part 32, and presses the bus bar 3 and the terminal 4 into the fixing die 22 by the pressing rod 47 of the pressing member 43. As shown in FIG. 8, the bus bar 3 and the terminal 4 are mounted on the fixing die 22. As shown in FIG. 9, the transfer apparatus 12 extends the rod 45 of the cylinder 42 for pressing in the member pressing part 32, and positions the attaching part 28 on the carrying-out unit 11 by driving the robot arm 27. The transfer apparatus 12 separates each chuck member 38 of the chuck cylinder 37, and mounts the box body 2 on the carrying-out unit 11. Furthermore, the transfer apparatus 12 reduces the rod 36 of the cylinder 34 for holding, and mounts the jig 13 on the carrying-out unit 11.
Thus, the transfer apparatus 12 mounts the jig 13 provided from the second transfer unit 9, and provides the bus bar 3 and the terminal 4 mounted on the jig 13 for the fixing die 22. Also, the transfer apparatus 12 carries the jig, which the bus bar 3 and the terminal 4 are removed, and the box body 2 which is formed by the die 22 and the die 23 to the carrying-out unit 11. As described above, the transfer apparatus 12 mounts the bus bar 3 and the terminal 4 into the fixed mold 22, and removes the box body 2, which is formed by the die 22 and 23, from the moving die 23.
The transfer apparatus 12 places the jig 13 and the box body 2 on the carrying-out unit 11. On the other hand, the injection molding apparatus 10 moves the moving die 23 close to the fixing die 22. After the cavity is closed, the cavity is filled with synthetic resin plasticized. The synthetic resin in the cavity becomes solidified, and the box body 2 is molded. Thereafter, the injection molding apparatus 10 presses the box body 2 in the cavity into the moving die 23 by the extrusion pin 25, and separate each the die 22 and the die 23. In addition, the box body 2 is mounted on the moving die 23. Thus, the above mentioned molded article production apparatus 5 forms the box body 2.
According to embodiments of the present invention, the component attaching part 30 is arranged on one surface 29a side of the main body 29 in the attaching part 28. The molded article attaching part 31 is arranged on another surface 29b side. Thereby, by positioning the attaching part 28 between the die 22 and 23, the bus bar 3 and the terminal 4 as a component of insert molding can be mounted into the fixing die 22. Also, the box body 2 as a molding can be removed from the moving die 23. Therefore, these actions, mounting the bus bar 3 and the terminal 4 into the fixing die 22 and removing the box body 2 from the moving die 23 can perform continuously.
The attaching part 28 mounts the bus bar 3 and the terminal 4 into the fixing die 22, and removes the box body 2 from the moving die 23. Thereby, it does not require arranging a transfer apparatus for mounting the bus bar 3 and the terminal 4 into the fixing die 22, and a transfer apparatus for removing the box body 2 from the moving die 23.
Therefore, working efficiency can be improved, and cost and space of the molded article production apparatus 5 can be controlled.
The member for preventing 15, which controls a fall of the bus bar 3 and the terminal 4, is arranged in the jig 13. The holding part 41 holding the jig 13 is arranged in the component attaching part 30 of the attaching part 28. Thereby, even if the jig 13 mounting the bus bar 3 and the terminal 4 is positioned in whatever place when the attaching part 28 is positioned between the die 22 and 23, a fall of the jig 13 from the attaching part 28, and a fall of the bus bar 3 and the terminal 4 from the jig 13 can be prevented.
Also, the attaching part 28 has the component pressing part 32, which presses the bus bar 3 and the terminal 4 into the fixing die 22 from the jig 13. Thereby, the bus bar 3 and the terminal 4 mounted on the jig 13 can be mounted into the fixing die 22 securely.
Therefore, even if the bus bar 3, the terminal 4 and the box body 2 are mounted on the attaching part 28 of one of the transfer apparatus 12, the bus bar 3 and the terminal 4 do not fall, and these can be mounted on the fixing die 22. Thereby, the box body 2 can be molded securely.
The molded article production apparatus 5 has the above mentioned transfer apparatus 12. Thereby, the working efficiency can be improved, and cost and space for inserting can be controlled.
According to the above mentioned embodiment, the box body 2 of an electronic connection box, which forms the bus bar 3 and the terminal 4 in a wiring harness 1 into an insert molding, is shown. However, the present invention can form various parts into insert molding not only the bus bar 3 and the terminal 4, and various parts not only the box body 2 of an electronic connection box can be formed. In short, the present invention can only form parts into insert molding.
While the invention has been described with reference to specific embodiments, the description is illustrative and not to be construed as limiting the scope of the invention. That is to say, various changes and modifications can be made without departing from the scope of the present invention.
