An impregnation member 21 is attached to the.

The impregnating member 21 has an annular shape having a wide rectangular cross-sectional shape similar to the mounting groove 19,
A portion that crosses the cut groove 18 is an opening. The impregnation member 21 mounted in the mounting groove 19 has an inner peripheral surface 21 a exposed in the grommet placement hole 14.

Further, the impregnating member 21 is made of a foam material (continuous pore foam material) having a large number of fine pores and communicating with each other, and is excellent in water absorption and moisture retention. In this embodiment, the impregnating member 21 is made of felt. However, the material of the impregnating member 21 is not limited to the felt, and may be a continuous pore foam made of synthetic resin such as urethane, nylon, and elastomer and having excellent water absorption and moisture retention.

The impregnation member 21 is impregnated with a liquid lubricant. In the first embodiment, oil and fat (Unilube) is used as the lubricant. However, the lubricant is not limited to fats and oils, and may be any liquid that can be absorbed by the impregnation member 21.

Next, the work of applying the lubricant to the grommet using the lubricant applying device for the grommet of the first embodiment will be described. First, as shown in FIG. 2A, the grommet 2 is attached to the wire harness W / H and fixed with the adhesive tape 23.

The wire harness W / H is placed in the grommet placement hole 14 and the wire harness placement hole 15 of the mold body 12 through the cut groove 18 so that the wire harness W / H projects from both side portions 12a and 12b of the mold body 12. At this time, since the large-diameter cylindrical portion 2b of the grommet 2 is wider than the groove width of the cut groove 18 and cannot pass through the cut groove 18, the wire harness is provided over the entire length of the cut groove 18. After positioning the wire harness W / H so that the W / H or the small-diameter cylinder portion 2a of the grommet 2 is located and the large-diameter cylinder portion 2b of the grommet 2 is outside the one side portion 12a of the mold body 12. , Wire harness W
/ H and the grommet 2 are inserted into the cut groove 18.

Next, the wire harness W / H and the grommet 2 inserted through the grommet placement hole 14 and the wire harness placement hole 15 are moved in parallel to the other side portion 12b side as shown by an arrow Y in FIG. 2 (A). Then, as shown in FIG. 2B, the small diameter tubular portion 2a of the grommet 2 is located in the wire harness placement hole 15, and the large diameter tubular portion 2b is the grommet placement hole 1.
It will be in the state of being located within 4. In this state, the outer surface of the large-diameter cylindrical portion 2b of the grommet 2 near the maximum diameter portion contacts the impregnating member 21, and the lubricant impregnated in the impregnating member 21 is applied to this portion.

When the wire harness W / H and the grommet 2 are removed from the mold body 12, the reverse operation to the above operation may be performed. That is, first, in the state shown in FIG. 2B, in the direction indicated by the arrow Z in FIG. 2A, the wire harness W /

In the structure of the second embodiment, the opening / closing valve 40 is normally closed. While repeating the operation of applying the lubricant to the grommet 2, the impregnation member 2
If the amount of lubricant impregnated in 1 decreases, at this time the on-off valve 4
0 is set to the valve open state. When the on-off valve 40 is opened, the liquid tank 3
The lubricant in 0 naturally flows from the conduit 36 to the supply groove 35 due to the difference in height between the liquid tank 30 and the grommet lubricant applying device 11 and the liquid pressure of the lubricant stored in the liquid tank 30. It is supplied to the impregnating member 21 through. At this time, since the lubricant is supplied to the impregnation member 21 from the plurality of connecting grooves 35b radially provided from the main supply groove 35a as described above,

It operates and stops based on the signal from.

A limit switch 47 constituting a detecting means is provided near the opening 14a on the peripheral wall of the grommet placement hole 14 of the mold 12. The limit switch 47 generates a signal when the contact piece 47a is pressed. This signal is input to the control means 46.

The control means 46 outputs a signal instructing the liquid feed pump 44 to operate each time the limit switch 47 is switched from the off state to the on state, and the limit switch is turned off from the on state. A signal for instructing the liquid feed pump 44 to stop is output each time the state is switched to the state.

In the third embodiment having the above-mentioned structure, the limit switch 47 is in the OFF state and the liquid feed pump 44 is stopped when the grommet 2 is not placed in the grommet placement hole 14 of the mold 12. There is. When the grommet 2 attached to the wire harness W / H is placed in the grommet placement hole 14, the limit switch 47 switches from the off state to the on state. At this time, the control means 4
6 outputs a signal instructing the liquid feed pump 44 to operate, and the liquid feed pump 44 operates.

When the grommet 2 is removed from the grommet placement hole 14, the limit switch 47 is switched from the ON state to the OFF state, and the control means 46 which detects this has been detected.

Claims (7)

[Claims] 1. A grommet placement hole in which a grommet is placed and housed, and a wire harness placement hole in which a wire harness equipped with a grommet is placed are continuously provided so as to pass through the die body, and are provided outside the die body. A lubricant application device for a grommet, characterized in that a cut groove is provided to connect the grommet placement hole and the wire harness placement hole, and an impregnating member impregnated with a lubricant is attached to a peripheral wall of the grommet placement hole. 2. The lubricant applying device for a grommet according to claim 1, further comprising a liquid tank in which a lubricant is stored and a liquid path connecting the liquid tank and the impregnating member. 3. A liquid tank in which a lubricant is stored, a liquid path connecting the liquid layer and the impregnating member, a detecting means for detecting that a grommet is arranged in the grommet arrangement hole, and the detecting means. The lubricant applying device for grommet according to claim 1, further comprising: a liquid feeding unit that is activated when it detects that the grommet is arranged, and feeds the lubricating liquid from the liquid tank to the impregnating member. 4. A wire in which a pair of openable and closable half halves form a grommet placement groove that forms a grommet placement hole in which a grommet is placed and housed in a closed state, and a wire harness in which the grommet is attached in a closed state. A wire harness placement groove that forms a harness placement hole is provided, and a detection means that detects that a grommet is placed in the grommet placement groove is provided in the grommet placement groove of each of the half-molded bodies. A lubricant applying device for grommets, which is equipped with an impregnating member impregnated with a lubricant. 5. The lubricant applying device for a grommet according to claim 4, wherein a liquid tank storing a lubricant and a liquid passage connecting the liquid tank and the impregnating member are provided. 6. A liquid tank in which a lubricant is stored, a liquid path connecting the liquid layer and the impregnating member, and when the detecting means detects the arrangement of the grommet, the liquid tank is changed to the impregnating member. The grommet lubricant application device according to claim 4, further comprising: a liquid feeding unit that feeds a lubricating liquid. 7. The impregnating member is made of a continuous porous body, and the impregnating member is made of a porous material.
The lubricant application device for the grommet according to the item.
