The present invention relates to an apparatus for manufacturing a head restraint for an automobile, which will be described in more detail. In order to manufacture the headrest, the foam of the foam is injected into the mold after the cover of the head restrained into the mold frame. It is intended to be carried out more quickly and easily to at the same time to ensure that a higher quality foaming liquid is injected to have a purpose in zoom.

In general, the headrest of the car seat supports the driver's back and neck, and the foam is injected and solidified in the cover made of natural or artificial leather to have a constant cushioning force. Looking at it,

First, the headrest stay 104 is inserted into the cover 103 of the headrest manufactured in a predetermined shape as shown in FIG. 13, and then, the headrest stay 104 is seated in the mold mold 7 so that the foam mold ( 7) Inject foaming liquid into

To describe this in more detail, as shown in FIG. 7, a plurality of mold frames 7 and a sensing bar 63 are spaced at a predetermined interval to the upper and lower portions of the turn table TURN TABLE 6 rotated by the rotary motor 61. Install each, one side of the turntable 6 to install the foam liquid injection device (8),

The foam injection device 8 is a structure that allows the transfer cylinder 82 to be transferred before and after the foam head 81 of the upper portion to the inlet 71 of the mold 7.

In addition, the front part of the foaming liquid injector 8 detects the sensing bar 63 of the turntable 6 that rotates, and a plurality of mold molds 7 at the upper portion thereof form the foaming head 81 of the foaming liquid injector 8. It is a structure made by installing the detection sensor 101 to stop, move to be located in the same line.

Therefore, when the cover 103 of the headrest is embedded in each of the mold molds 7 installed in the upper part of the turntable 6 as shown in FIGS. 7, 8 and 9, the turn table 6 has a plurality of mold molds 7. ) Is sequentially rotated so as to be in line with the foam liquid injection device (8), wherein the turntable (6) is driven to the lower end of the position where the mold frame (8) is installed, respectively, the sensing bar (63) When the turntable 6 is rotated, the detection sensor 101 installed at the front of the foam injection device 8 detects the detection bar 63 to stop the rotation of the turntable 6. In this case, the plurality of molds 7 installed on the turntable 6 can be positioned in the same line as the foam liquid injector 8 in sequence.

In addition, when the turntable 6 is stopped by one of the molds 7 of the plurality of molds 7 by the detection sensor 101 to be in line with the foaming solution injector 8, the foaming liquid is injected. While the foam head 81 of the apparatus 8 moves forward and moves by the transfer cylinder 82, the foam liquid inlet 83 of the foam head 81 is brought into close contact with the inlet 71 of the mold 7. A certain amount of foam is injected into the mold (7). At this time, the inlet (71) of the mold (7) does not leave any residue of the foam and at the same time the inlet (71) is applied to the foam. Inlet 72 is provided separately to solve problems such as clogging.

When a certain amount of foam is injected into the mold, the foam head is returned to its original position by the transfer cylinder, and the turntable is stopped by a sensor while rotating the next mold to be positioned in the same line as the foam liquid injector. The above process is repeated.

As described above, the headrest manufacturing apparatus insulates the cover of the headrest into a plurality of mold molds, and then rotates it with a turntable, and sequentially injects the foaming liquid into the die mold with the foaming liquid injector, thereby providing the headrest within a short time. It enables to manufacture a large amount.

However, the conventional headrest manufacturing apparatus as described above has the advantage of manufacturing a large amount of headrests in a short time, but the amount of the ratio was very high.

That is, when the foam head is injected into a plurality of mold molds on the turntable during the manufacture of the headrest by using the headrest manufacturing apparatus, the foam head of the foam liquid injector is advanced by the cylinder, and the foam liquid inlet in the front portion of the mold mold is moved. Close to the inlet of the foam to inject the foam,

At this time, the inlet of the mold to prevent the foaming liquid is buried around the solidification and at the same time to prevent the inlet to be blocked by the remaining foaming liquid to separate the injection port by the worker before the injection of the foaming foam In addition to the inconvenience of having to be installed in the part, the cost was too high. Furthermore, the foam injection portion of the foam head for injecting the foam liquid buried with the remaining foam liquid after injecting the foreign matter in the next foam liquid injection. Of course, if the mixing is severe, the foam liquid coagulates and blocks the foam liquid inlet, which leads to a defect of the headrest. Therefore, in order to solve the problem, the worker always cleans the foam liquid inlet after the injection of the foam liquid. There is a hassle to make and the production time of the headrest Soyodoem course it would have been the evils which such work rate is very poor.

As described above, the conventional headrest manufacturing apparatus may provide the convenience of work because the cover of the headrest is installed in a plurality of mold frames to sequentially inject the foaming liquid into the mold. In addition to the introduction of the inlet as well as the need to clean the foam inlet in the air condition, the worker's work efficiency is very low, and the manufacturing process of the headrest takes a long time.

The present invention has been made in order to solve the above conventional problems, in particular when the injection of the foam liquid into the mold by installing the foam liquid injection connection device and the cleaning device between the foam liquid injection device and the turntable of the headrest manufacturing apparatus Since the foam liquid is introduced into the mold through the foam liquid injection connection device, it prevents the foam liquid dregs from occurring at the inlet of the mold and prevents the blockage accordingly, and furthermore, when the injection of the foam liquid is completed, the foam liquid is completed. The inlet is cleaned with a cleaning device to prevent the foam residue remaining around it from solidifying, so that a higher quality foam can be injected so that the failure rate of the headrest can be minimized. will be.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
