2. Description of the Related Art When an automobile door lining is exemplified as a resin molded product, as shown in FIG. 18, a skin material obtained by cutting a sheet material made of a material different from a general surface such as genuine leather, synthetic leather or fabric into a predetermined area shape. By partially attaching H to the upper side of the armrest A, the center pad P
Is provided on the front surface side of the lining body R.

To provide the center pad P, the structure shown in FIG.
When the lining body R is resin-molded as shown in FIG. 9, a wood grain groove g is provided on the front surface side for winding and fixing the outer peripheral edge of the skin material, and the outer peripheral edge h of the skin material H is formed as shown in FIG. It is carried out that the skin material H is partially attached by post-wrapping it by being rolled up in g.

When the cut-out shape of the skin material H including the outer peripheral edge and the contour shape of the wood grain groove g do not match in the retrofitting of the skin material, as shown in FIG. g is exposed to the outside, or FIG.
As shown by (4), the outer peripheral edge h is rolled out due to the outer peripheral edge excess due to the overly wide skin material H. Further, if the thickness of the skin material and the groove width of the wood grain groove do not match, it is impossible to wind the outer peripheral edge due to the skin material being too thick, or a gap is formed in the wood grain groove due to the skin material being too thin.

When the skin material is retrofitted, not only is it necessary to strictly control the cut shape, the thickness of the skin material, the contour shape of the wood-grained groove, the groove width, etc., but also the skin material is misaligned and twisted and wrinkled. Alternatively, it is required to bond them carefully so as not to cause swelling due to the intake of air, which is a very troublesome work.

On the other hand, as shown in FIG. 23, a core mold M ₁ having a concave groove G on the mold surface and a convex portion B for inserting the outer peripheral edge h of the skin material H into the concave groove G of the core mold M _1. Using the cavity mold M ₂ provided with the above, the general part r ₁ of the lining body R and the lining part r ₂ of the outer covering skin part are entirely injection-molded, and at the same time, the outer peripheral edge h of the skin material H is made into the core mold M _1. The skin material H is partially adhered by embedding it in the groove of the wood grain groove g by the concave groove G.

In the partial skin attachment and the simultaneous molding of the lining body, it is possible to prevent the skin material from being misaligned, twisted wrinkles, or swelling due to the intake of air. However, as shown in FIG. The trace left by is the wood grain groove g
Since it remains as a gap of No. 6, the gap of the wood grain groove g is exposed to the outside of the product.

Instead of simultaneously molding the lining body from the general portion of the lining body as a whole, first, the lining portion of the outer covering skin is injection-molded, and then the general portion of the lining body is injection-molded to form the skin. A method for manufacturing a resin molded product in which the outer peripheral edge of the material is embedded and held in the joint between the lining portion of the skin material and the general portion of the lining body to integrally form the lining portion of the exterior skin portion and the general portion of the lining body. Has been proposed (JP-A-8-30038).
No. 0).

The manufacturing method of the resin molded product is composed of a core mold 20 and a cavity mold 21 as shown in FIG. 25, and has a contour shape corresponding to the cut shape of the skin material H, and the mold surface of the cavity mold 21. The slide groove 22 that moves forward or backward toward the inside is provided in the mold of the core mold 20, and the inner peripheral surface of the slide block 22 defines the groove outer circumference.
3 is provided on the mold surface of the core mold 20, and the molding die in which the protruding teeth 24 whose tooth tips are aligned with the inner peripheral edge of the slide block 22 are provided on the mold surface of the cavity mold 21 is disclosed.

In the molding die, first, the outer peripheral edge h of the skin material H is received by the tip surface of the slide block 22 when the mold is opened, and the skin material H is pressed against and supported by the slide block 22 on the mold surface of the cavity mold 21. Then, after the molten resin E ₁ is injected from the resin injection gate 25 to the mold surface of the core mold 20 in the frame of the slide block 22, the outer peripheral edge h of the skin material H is slid while receiving the outer peripheral edge h of the slide block 22. Block 22
The cavity mold 21 is moved toward the core mold 20 while pressing and retracting.

When the core die 20 is clamped by the cavity die 21, the outer peripheral edge h of the skin material H is sandwiched between the tip surface of the slide block 22 and the protruding teeth 24 of the cavity die 21 as shown in FIG. The ridges 24 are provided on the side of forming the lining portion, which is integrated with the outer cover, and on the side of forming the general portion of the molded product.
First, the molten resin injected into the mold surface of the core mold 20 is made to flow from the back surface side of the cover skin portion to the inside of the receiving groove 22 defined by the slide block 22, so that the cover skin portion is formed. Forming a backing portion r ₂ having a flange portion f ₂ rising on the back surface side of the.

After forming the lining portion r ₂ , as shown in FIG. 27, the slide block 22 is retracted to near the groove bottom of the receiving groove 23 to move the outer peripheral edge h of the skin material H to the cavity mold 21.
Release the pressure contact with the mold surface of. By releasing the pressure contact of the outer peripheral edge by the slide block 22, the outer peripheral edge h of the skin material H hangs in the empty space of the slide block 22 by its own weight, and the molten resin E ₂ is formed into a general part of the molded product as shown in FIG. 28. The lining body is generally filled with the liquid by injecting it from the side to fill the empty space of the slide block 22.
₁ is formed.

Flange _{F 2} a of the outer peripheral edge of the backing portion _{r 2} and the general portion _{r 1}
While the embedding held by the flange portion F _1, is disclosed to form a generally integral lining body R by joining the backing portion r ₂ and the general portion r ₁ in mutual flange portion F _1, F ₂ ing.

However, in the method of manufacturing the resin molded product, even when the outer peripheral edge of the outer peripheral edge of the outer peripheral edge h of the outer peripheral edge of the outer peripheral edge h of the outer peripheral edge of the outer peripheral edge of the outer peripheral edge h of the outer peripheral edge of the outer peripheral material H is adhered to the outer peripheral edge of the outer peripheral material by the sliding block 22. Does not always hang down in the empty space of the slide block 22 by its own weight (see FIG. 27).

When the molten resin E ₂ is injected into the general part forming side of the molded product without the outer peripheral edge of the skin material hanging down, the molten resin E ₂ flows from the outer peripheral edge of the skin material to the lower side and the outside of the skin material The peripheral edge is exposed to the front surface side, or the outer peripheral edge of the skin material is pressed by the injection pressure of the molten resin E ₂ and is crushed, so that the peripheral edge is curled and solidified.

Therefore, in the above-described method for manufacturing a resin molded product, as shown in FIG. 30, the vacuum ventilation passage 26 communicating with the inside of the receiving groove 23 is provided on the inner side of the receiving groove 23 and the outer peripheral edge h of the skin material H. Is forced to hang into the empty space of the slide block 22.

However, in this case, the slide block 22 is once retracted to the communicating position of the vacuum ventilation passage 26, and the vacuum pressure is applied to the inside of the groove 23 to force the outer peripheral edge of the skin material into the empty space of the slide block 22. Since the slide block 22 must be advanced again to the groove bottom of the receiving groove 23 as shown in FIG. 31, after it is hung down, the molding cycle becomes complicated and the time required for molding the entire lining takes a long time.

In particular, when the skin material is a breathable material such as a fabric, it is difficult to force the skin material to hang down securely into the empty space of the slide block 22 by vacuum pressure. ₂ flows from the outer peripheral edge of the skin material to the lower side to expose the outer peripheral edge of the skin material to the surface side, or
It is unavoidable that the outer peripheral edge of the skin material is pressed by the injection pressure of the molten resin E ₂ and is crushed to be wrinkled.

In addition to the resin molding described above, a plurality of small protrusions are provided on the outer peripheral edge of the skin material for positioning and fixing, and the small protrusions are inserted into the core type receiving groove and the outer peripheral edge of the skin material is provided. To the core-type wood grain groove to assemble the skin material onto the core-type mold surface, inject the molten resin from the core-type resin injection gate to the back side of the cover-skin, and mold the lining to form the skin. It has been proposed that a resin molded product is formed integrally with a skin material while preventing the material from shifting and wrinkling (Japanese Patent Laid-Open No. 2000-238088).

The method for producing the resin molded product is such that the molten resin injected to the back surface side of the outer skin portion is made to flow outward from the outer peripheral edge of the outer skin material to form a flange portion continuous from the lining portion of the outer skin portion. Is also disclosed. However, according to this method for producing a resin molded product, since the molten resin is only allowed to wrap around the outer peripheral edge of the skin material to form the flange portion, the general portion of the lining body is formed from the outer peripheral flange portion. As such, it lacks joint strength with the backing.
