面材を上側、基材を下側にすることが多い。2. Description of the Related Art Press forming methods shown in FIGS. 6 to 8 are widely used as a method for forming a laminated body used for an automobile forming ceiling or the like. The press molding method includes a surface material 31,
The laminated member 30 including at least the base material 33 and the adhesive layer 35 provided between the two layers is sandwiched between the lower mold 41 mold surface 43 and the upper mold 45 mold surface 47 of the heated press mold 40 and pressure bonded,
This is a method of melting or reacting the adhesive layer 35 by the heat of the press die to integrate the laminated member 30 and shape it into a die surface shape. As the base material 33, a material in which a foam is impregnated with a curable resin that is cured by heat, or a material in which glass fibers are laminated on the foam is used. As the adhesive layer 35, a hot melt film that melts by heating to weld the surface material and the base material,
Alternatively, an adhesive or the like that exhibits adhesiveness by reacting by heating is used. In addition, in order to obtain a good appearance of the laminated body, or in view of the structure of the molding device, the surface material of the laminated member is often on the upper side, and the base material is often on the lower side.

らないのが一般的である。In the above-mentioned press molding method, a laminated member larger than the press die is used for holding the laminated member 30 before or after crimping when the mold is opened.
The edge of the laminated member protruding from the edge of the press die is held by a holder 50 such as a clip tenter. The holding of the laminated member 30 is usually performed by pulling the edge of the surface material 31 outward so as not to cause wrinkles on the surface material 31 during molding. Also, even in the mold open state after crimping and shaping,
The edge of the surface material 31 is pulled and held as it is so as to be floated between the molds, and a clip tenter or the like is moved in that state to take out the molded laminate from the mold. Since the base material 33 is often configured to include a foamed material, when the base material 33 is pulled by the holder 50, the thickness of the base material becomes thin and the desired thickness of the laminate is obtained. Since it will not be obtained, it is generally not pulled.

The edges of the laminated member protruding from the press die are not integrated because they are not crimped and heated by the press die, and peeling easily progresses from the edge portion toward the center during subsequent trimming etc. There is.

の後に積層部材の縁で剥離を生じ易くなる。Moreover, in the above press molding method,
Even during the molding, there was a cause of peeling from the edge of the molded member and subsequent peeling. First, at the time of crimping, as described above, since the surface material is crimped and shaped so as to be stretched by the press die in a state where the edge of the surface material is pulled outward, as shown in FIG. Tends to be thinned by being pulled together with the surface material. Therefore, the laminated member 30 does not adhere to the press die at the edge of the die surface,
It becomes difficult for heat of the press die to be transferred into the laminated member 30, which causes insufficient adhesion or adhesion of the adhesive layer, and then easily causes peeling at the edge of the laminated member.

が多いため、自重で縁から剥離し易かった。When the mold is opened after crimping, the edge of the surface material is held as described above, and in the vicinity of the edge,
That is, since the laminated member is not integrated at the portion protruding from the press die, as shown in FIG. 8, the edge of the base material 33 located on the lower side may hang down due to its own weight, and peeling may start. In particular, the base material 33 is often heavy because it is impregnated with a curable resin or a glass fiber layer is laminated, and thus the base material 33 is easily peeled from the edge by its own weight.

こともあった。Further, since the edge of the die surface is a portion corresponding to the edge of the laminated body which is usually cut off by trimming after that, the temperature is not controlled accurately as compared with the central portion of the die surface, and moreover, the periphery of the press die. This is a portion that is easily affected by the ambient temperature of. Therefore, the temperature of the edge of the mold surface tends to be lower than that of the central portion, and even if the degree of pressure bonding of the laminated member or the degree of contact between the laminated member and the press die is the same between the center of the mold surface and the edge of the mold surface. Even in such a case, the degree of heating of the laminated member was weak at the edge of the mold surface, and the integral integration of the laminated member was likely to be incomplete.

In a press molding method for a laminate that is integrated with and is shaped into the mold surface shape of the press mold, a protrusion is formed at the edge of the mold surface of the press mold, It is characterized in that the laminated member is strongly pressure-bonded with the protrusion.

る。[Operation] When press-bonding the laminated members, at the edge of the die surface of the press die,
The protrusion formed on the edge bites into the laminated member, and the laminated member is strongly pressed. Therefore, the thickness of the laminated member becomes thin at the pressure-bonded portion, the distance between the press die and the inside of the laminated member becomes small, and heat of the press die is easily transferred into the laminated member. Further, even when the base material becomes thin at the edge of the mold surface by pulling the edge of the surface material, the presence of the protrusions at the edge of the mold surface ensures that the laminated member is in close contact with the press mold. Therefore, the heat of the press die can be satisfactorily transferred into the laminate member without forming a gap between the press die and the laminate member. As a result, even at the edge of the mold surface, the adhesive layer inside the laminated member is sufficiently heated by the heat of the press die to exhibit strong weldability or adhesiveness, and the edge of the laminated member is reliably integrated.

Therefore, the peeling stops at the pressure-bonded portion by the protrusion 19. Moreover, if the product is designed in advance so as to be trimmed at a position slightly inward of the crimped portion formed by the protrusion 19, the final product obtained will be a good laminate without peeling of the edges. Of course, depending on the application of the laminated body, the laminated body may be trimmed while leaving the pressure-bonding portion.

が得られる。When the laminated member 30 composed of a continuous body is supplied to the press die 10 for continuous forming, the press die 1 is used.
After opening 0, the laminated member is conveyed to a cutting device in front of the press die 10 and cut into a predetermined size there. Further, in the above description, an example in which the base material is arranged on the lower side of the surface material is shown. You may arrange | position and shape. Even in that case, a laminate which is hard to be peeled from the edge can be obtained.
