  The present invention relates to a molding method and apparatus for resin molded parts.

  Various types of resin molded parts are used in various places in vehicles such as automobiles. Among such resin molded parts, there is one by insert molding (see, for example, Patent Document 1).

  For example, in the case of an instrument panel installed in the front part of a passenger compartment, a preformed skin material is set in a resin molding die, and a resin raw material is injected into the resin molding die in which the skin material is set. Thus, an instrument panel (resin molded part) in which the skin material is integrated with the resin part body is insert-molded.

  At this time, when the skin material has a size extending over the entire instrument panel, the positioning of the skin material with respect to the resin molding die is provided in a portion outside the molding space of the resin molding die. It can carry out between a positioning part and the positioning part provided in the part outside the product of a skin material.

  On the other hand, as shown in FIG. 14, when the skin material 1 is partially inserted into the instrument panel 2 (resin molded part 3), that is, inserted into the instrument panel 2. When the skin material 1 is small, the positioning portion described above cannot be provided directly in the molding space of the resin molding die or in the molding space of the skin material. Means are used.

By positioning and holding the positioning ear 51, the skin material 21 can be positioned with respect to the skin receiving base 24. Thereby, it becomes possible to more accurately set the skin material 21 to the resin molding die 26 by the transfer device 27. Accordingly, it is possible to prevent the positional deviation of the skin material 21 in the molded resin molded part 23 and the product failure of the resin molded part 23. In addition, by providing the ear cutting device 53 in the skin receiving base 24 or the transfer device 27, it is unnecessary when the skin material 21 is transferred from the skin receiving base 24 to the resin molding die 26 by the transfer device 27. The resulting positioning ear 51 can be cut from the skin material 21 using the ear cutting device 53. Thereby, the skin material 21 can be set in the resin molding die 26 without the positioning ear 51.

  (B) A skin receiving base 24 on which the pre-formed skin material 21 can be placed, and a resin molding die 26 capable of insert molding of a resin molded part 23 in which the skin material 21 is integrated with a resin part body 25; In the molding apparatus for the resin molded part 23, the skin material 21 is provided with a transfer device 27 that transfers the skin material 21 from the skin cradle 24 to the resin molding die 26 and can be set on the resin molding die 26. 21 is provided with a positioning ear 51 at the edge thereof, and a positioning ear holding portion 52 for positioning and holding the positioning ear 51 is provided at a position corresponding to the positioning ear 51 of the skin receiving base 24. By providing the cradle 24 or the transfer device 27 with the ear part cutting device 53 capable of cutting the positioning ear part 51 of the skin material 21, the same effect as described above can be obtained.

  (C) In the above, by providing the ear pressing device 54 for pressing the positioning ear 51 positioned and held by the positioning ear holding portion 52 on the skin receiving base 24, the following effects can be obtained. Can do.

  That is, by providing the ear pressing device 54 on the skin receiving base 24, the positioning ear 51 positioned and held by the positioning ear holding portion 52 is pressed by the ear pressing device 54, and the ear cutting is performed. It can be cut with the device 53. As a result, the positioning ear 51 can be prevented from floating, twisting, and fluttering, so that the positioning ear 51 can be cut more cleanly with respect to the skin material 21, and the shape of the cut portion can be reduced. In addition to stabilization, cutting defects can be eliminated.

  (D) In the above, the transfer device 27 is provided with the ear removing device 55 capable of removing the positioning ear 51 cut by the ear cutting device 53 from the positioning ear holding portion 52, and this ear removing device. 55 includes an ear suction mechanism 56 configured to suck the positioning ear 51 that has been cut and to discard the positioning ear 51 during the movement of the transfer device 27 by releasing suction. The following effects can be obtained.

  That is, by providing the ear part removing device 55, the positioning ear part 51 cut from the skin material 21 can be removed automatically and reliably. Thereby, the trouble of removing the positioning ear 51 from the positioning ear holder 52 can be saved. Also, by providing the ear removal device 55 in the transfer device 27, the positioning ear 51 is removed using the movement of the transfer device 27 or in conjunction with the movement of the transfer device 27. Can do. Thereby, the structure of the ear | edge part removal apparatus 55 can be simplified. And the ear | edge part removal apparatus 55 was equipped with the ear | edge part adsorption | suction mechanism 56, by adsorb | sucking the positioning ear | edge part 51 cut | disconnected from the skin material 21, and releasing adsorption | suction during the movement of the transfer apparatus 27, The positioning ear 51 can be discarded in the middle.

  (E) In the above, since the ear part removing device 55 is the ear part pressing member 57 that presses the positioning ear part 51 that is positioned and held by the positioning ear holding part 52, the following effects are obtained. be able to.

  That is, by using the ear part removing device 55 as the ear part pressing member 57, the positioning ear part 51 positioned and held by the positioning ear holding part 52 is pressed by the ear part pressing member 57, and the ear part is placed. It can cut | disconnect with the cutting device 53. FIG. As a result, the positioning ear 51 can be prevented from floating, twisting, and fluttering, so that the positioning ear 51 can be cut more cleanly with respect to the skin material 21, and the shape of the cut portion can be reduced. In addition to stabilization, cutting defects can be eliminated. Further, by using the ear part removing device 55 as the ear part pressing member 57, it is not necessary to provide the ear part pressing device 54 in the skin receiving base 24, or the ear part pressing apparatus 54 provided in the skin receiving base 24.
