The mold holder 231 has a plurality of guide grooves 231a formed at the front edge portion thereof.

The mold frame 232 has a guide protrusion 232a inserted into the guide groove 231a at a rear edge portion thereof.

The conveying apparatus 300 includes a moving head 310, an elastic rod 320 that is elastically installed on the movable head 310, a first jig 330 that is installed on the elastic rod 320, and It is configured to include a second jig 340 is installed below the first jig 330.

The moving head 310 moves in the X-axis and Y-axis directions on the upper sides of the first molding apparatus 100 and the second molding apparatus 200. That is, the moving head 310 moves in the front and rear and left and right directions on the first and second cases 110 and 210.

The elastic rod 320 is installed in the moving head 310, the length is adjusted in the same manner as the antenna in the Z-axis direction. That is, the length of the expansion rod 320 is adjusted in the vertical direction. Therefore, since the moving head 310 moves in the X-axis and Y-axis directions, and the extension rod 320 is adjusted in the Z-axis direction, the first jig 330 and the second jig ( 340 will eventually be able to move in the XYZ axis.

The first jig 330 is installed at the lower end of the elastic rod 320 and the inside and outside of the first case 110 and the second case 210 through the first entrance 110a and the second entrance 210a. As a result, the two opening and closing plates 11 injection-molded by the first molding apparatus 100 are simultaneously taken out and then mounted on the second movable mold 230 of the second molding apparatus 200 at the same time.

In other words, the first jig 330 enters the first and second cases 110 and 210 when the length of the elastic rods 320 is increased, and the first and second cases 110 and 210 are shortened when the length of the elastic rods 320 is shortened. The first jig 330 goes out.

The first jig 330 is provided with a suction member 331, the pressing member 332.

The suction member 331 is a component that sucks the opening and closing plate 11 when the opening and closing plate 11 mounted on the first movable mold 130 of the first molding apparatus 100 is taken out. The suction member 331 removes the opening and closing plate 11 from the first movable mold 130 by the suction force provided from the suction device (not shown).

The pressing member 332 is a part for pressing the opening and closing plate 11 when the opening and closing plate 11 is mounted on the second movable mold 230 of the second molding apparatus 200. In other words, the opening and closing plate 11 is removed from the first movable mold 130 by the adsorption member 331, and the removed opening and closing plate 11 is mounted on the second movable mold 230 by the pressing member 332.

Here, the end surface of the pressing member 332 is preferably embossed (332a). Since the opening and closing plate 11 may not be sufficiently solidified until the opening and closing plate 11 removed from the first movable mold 130 is mounted on the second movable mold 230, the opening and closing plate 11 may be removed. When the opening and closing plate 11 is pressed to the end of the pressing member 332 when pressed, the opening and closing plate 11 may not be mounted at the correct position of the second movable mold 230. In order to prevent such a phenomenon, the end of the opening and closing plate 11 is embossed 332a to reduce the contact area with the opening and closing plate 11 while pressing the opening and closing plate 11.

In consideration of the high temperature of the opening and closing plate 11, it is also preferable to coat the end of the pressing member 332 with Teflon having heat resistance, corrosion resistance, and low frictional force.

The second jig 340 is installed at the lower end of the first jig 330 and the first case 110 and the first through the first entrance 110a and the second entrance 210a together with the first jig 330. By moving in and out of the two cases 210, the two molded articles 10 completed by the second molding apparatus 200 are simultaneously taken out.

The second jig 340 is provided with a suction member (341).

The adsorption member 341 is a component that adsorbs the molded article 10 when the finished molded article 10 attached to the second movable mold 230 of the second molding apparatus 200 is taken out. The suction member 341 separates the molded product 10 including the opening and closing plate 11 and the sealing part 12 from the second movable mold 230 by the suction force provided from the suction device.

Looking at the operation of the vehicle double injection molded article manufacturing system according to the present invention configured as described above are as follows.

First, two opening and closing plates 11 of the molded product 10 are molded at the same time by injection of plastic in the first molding apparatus 100. Then, the rubber is injection molded in the second molding apparatus 200 to simultaneously complete the two vehicle molded articles 10 having the sealing portion 12 provided at the edge of the opening and closing plate 11.

After the moving head 310 moves to the upper side of the first entrance 110a of the first case 110, the elastic rod 320 is elongated so that the first jig 330 and the second jig 340 may be the first case ( 110) Go inside.

Between the first fixed mold 120 and the first movable mold 130, the first jig 330 is advanced toward the first movable mold 130 and two opening and closing plates mounted on the first movable mold 130 ( 11) is simultaneously adsorbed by the adsorption member 331 and then taken out.

The elastic rod 320 is contracted and the moving head 310 moves toward the second entrance 210a of the second case 210.

The elastic rod 320 is extended so that the second jig 340 installed at the lower end of the first jig 330 enters between the second fixed mold 220 and the second movable mold 230 of the second molding apparatus 200. .

The second jig 340 is advanced toward the second movable mold 230 to simultaneously adsorb the two completed molded articles 10 mounted on the second movable mold 230 to the adsorption member 341.

Thereafter, the stretching rod 320 is further extended so that the first jig 330 enters between the second fixed mold 220 and the second movable mold 230.

The first jig 330 is advanced toward the second movable mold 230 to simultaneously mount the two opening and closing plates 11 on the second movable mold 230.

The elastic rod 320 is contracted so that the first jig 330 and the second jig 340 exit the second molding apparatus 200, and then the moving head 310 is moved to the first molding apparatus 100 and the second molding. Move to the place of loading between the devices 200.

The stretchable rod 320 is extended on the loading place, and the suction force for the second jig 340 is stopped, and the molded article 10 attached to the suction member 341 of the second jig 340 is loaded at the loading place. .
