The feature is that a wiring fitting is formed on one end of the cord set in the frame, and then supplied to a second molding machine to form a wiring fitting on the other end of the cord set in the holding frame. have. [Function] According to the present invention, in order to continuously supply the cord to the first molding machine and the second molding machine while it is initially set in the holding frame that holds both ends of the cord, the cord is transferred in the middle. It's not necessary. [Example] An example of the present invention will be described below in detail based on the illustrated apparatus. FIG. 1 shows a first molding machine 3a and a second molding machine 3b used in the present invention. , between the re-molding machines 3a and 3b disposed adjacent to each other, there is a molding section 3 of both of them.
A connecting rail 34 connecting the molding machine 3b is provided, and a return path 35 is provided connecting the take-out part 32 of the second molding machine 3b and the supply part 31 of the first molding machine 3a. After the cord 31 is set in the supply section 31, it is passed through the forming section 30 of the first forming machine 3a to the connecting rail 3.
4 to the molding section 30 of the second molding machine 3b, and after the cord 31 is taken out at the take-out section 32, the holding frame 2 is sent back to the supply section 31 through the return path 35. As shown in FIG. 4, one is used that holds both ends of the cord 1 at the same time. The cord 1 set in the holding frame 2 is made of thermosetting synthetic resin and has a rotary block 52 provided with a pair of plug blades 51, 51 in advance at one end thereof, and a plug blade holder at the other end. The container body is provided as a primary molding, and in the first molding machine 3a, the tap 4 is formed by covering the container body with thermoplastic synthetic resin, and then in the second molding machine 3b. The plug 5 is formed by molding the cap 50 that rotatably holds the rotating block 52. The holding frame 2, which has a rectangular frame shape, has a negative side that serves as a functional part for holding the rotating block 52 and the vessel provided at both ends of the cord 1, and the other side that is parallel to the negative side serves as a functional part for holding the rotating block 52 and the body provided at both ends of the cord 1. This is a clamp part 20 that clamps the middle part, and the holding part in the functional part will first be explained about the rotating block 52 side. Sometimes, the plug blade 51 is provided with an engaging pin 21 that engages with a hole formed in the blade 51. This engagement pin 21 is connected to the spring 2
As shown on the right side of the pair of rotating blocks 52 shown in FIG. 3, a release member (see FIG. (not shown) is slide block 2
3 is moved backward against the spring 22, the engagement pin 21 is removed from the stopper blade 51, and if the release member no longer presses the slide block 23, the engagement pin 21 is pushed back against the stopper blade 51 by the urging force of the spring 22. It is intended to be engaged with. As shown in FIG. 4, the holding part of the container body at the other end of the cord 1 is a movable member that is further slidable with respect to the slide core 24 and has a blade-like protrusion 26 at the tip. It consists of a body 25 and a slider 27 for sliding the movable body 25. The slider 27 here is equipped with a cam groove 28 in which a pin 25a protruding from the movable body 25 is slidably engaged, and when the slider 27 is slidably driven, the cam groove 28 is tilted. , the movable body 25 slides with respect to the holding frame 2 and the slide core 24. The container is held by projecting the movable body 25 into the holding frame 2 and inserting the blade-shaped protrusion 26 into the container. Moreover, as shown in FIG. 4, the slide core 24 here has an inclined surface on the other end upper surface side, and the first
When it receives pressure from the drive bottle 37 provided on the upper mold in the molding section of the molding machine 3a, it moves toward the container body and brings its one end surface into close contact with the container body. In order to form the tap 4 and the plug 5 on both ends of the cord 1, both ends of the cord 1 are set in the holding frame 2 as described above, and this holding frame 2 is transferred from the supply section 31 to the first molding. This molding machine 3a is supplied to the molding machine 3a.
In the molding section 30 of a, injection molding is performed to cover the body of one end of the cord 1. After that, attach the holding frame 2 to the connecting rail 34.
The plug 5 is formed by injection molding a cap 50 that rotatably holds a rotary block 52. And take-out part 3
2, the plug 5 and the tap 4 are released from the engagement pin 21 and the protrusion 26, and the cord 1, which has the plug 5 formed at one end and the tap 4 formed at the other end, is taken out.

ある。As described above, in the present invention, in order to continuously supply the cord to the first molding machine and the second molding machine while it is initially set in the holding frame that holds both ends of the cord, the parts are transferred midway through the process. This process does not require a changing process, and since both ends of the cord are held in the same holding frame, the other end of the cord does not get in the way unlike when only one end is held. There is no need for a special transport jig, and there are fewer steps before and after the molding process, so space can be saved and costs can be reduced.
