てい友。Conventional technology Conventionally, when making a molded product by attaching a foam-backed laminate material C (hereinafter referred to as a sub-insert) to a blow molding main body C (hereinafter referred to as a main insert),
A method in which a sub-insert is placed in advance in a residual dust cavity, the resin material is extruded from a die into a parison, and the parison is blow-molded, the sub-insert is contacted and polymerized with the parison, and then the mold is released and molded. Mold equipment is adopted.

込成形により成形することは困難であった。Problems to be Solved by the Invention According to the conventional method and mold apparatus, the peripheral edge of the outer laminate, which is a part of the secondary insert, is damaged after 1 lia due to expansion of the foam due to heat during molding. The terminal of the sub-insert protrudes from the surface of the main insert at the boundary between the sub-insert and the main insert. The outer surface of the insert is exposed and looks unsightly, and the heat of the parison and its expansion process disturbs the boundary between the sub-insert and the main insert, spoiling the aesthetics and imposing design constraints. There are technical gaps in the end treatment of laminate materials that are used to back the foam during blow molding, such as lowering the product value. For this reason, although blow molding is a useful molding method, in blow molding, a foam-backed laminate material is not used as a sub-insert material, but on the contrary, a material with a foam lining is used as a sub-insert material. In some cases, it was difficult to mold by blow molding.

を高めることを目的とし友ものである。The present invention aims to eliminate the drawbacks of the conventional method by forming a groove in the main insert at a portion corresponding to the boundary between the sub-insert and the main insert when the entire parison is formed in the mold by blow molding. By forming this groove on the edge or end of the sub-insert and contacting or sandwiching or covering the folded surface, the protrusion or exposure of the end of the sub-insert is eliminated and the appearance of the boundary is improved, The purpose is to enhance the beauty and product value of molded products.

) at a position corresponding to the boundary (7). Therefore,
The boundaries between the two will differ depending on the overall shape of the laminate material (3) with the foam (2) relative to the plow body (1). Then, the pre-cut laminate material (3) with the foam (2) is separated by the plate-shaped protrusions (C1) and loaded into the DJ. The outer surface (3b) of material (3) is a protrusion (C)
The folded surface (5) of the end of the laminate (3) (C38) is in contact with the cavity (B) in the area (D) of (A) as shown in FIG. ) inside (O
The length should be such that it reaches the tip (a!1) of t) or, as shown in Figure @6, reaches at most the tip (02)' and halfway to the outside (C8).

で溶着固定される。As mentioned above, after loading the rho-laminate material (3) with the foam (2) into the cavity (B) of the mold, it is blow-molded into the mold pronation, and after curing, the resin (4) becomes the molding resin. When inflated, the injected gas pressure causes the parison to move into the cavity of the mold (Bl, outside of the plate-like protrusion (C) (0)
8) and the tip (C2) is pressed against the folded surface (5) of the foam (2) and laminate material (3). On this occasion,
The foam (2) is heated by the heat during blow molding and the heat of the baricin and becomes ready for *S, but the expansion is prevented by the pressure applied by the swelling of the baricin due to the pressure of the blown gas. At the same time, the parison comes into contact with the foam (2) and is deposited on the surface of the baricine by thermal welding or anchoring effect. T section 11 surrounded by plate-like protrusions (C)
jl! Outside tDl, it is molded in direct contact with the outside (C8) of the plate-like protrusion (C), and in the pronation the laminate material (
A groove (8) is formed along the inside (C1) of the plate-shaped protrusion (C1) by sandwiching the folded surface (5) of the end edge (3a) of 3).
Therefore, the edge (3a) or the folded surface (5) of the laminate material (3) comes into contact with the groove (6) [Fig. Figure (C) is shown and fixed by welding in the next state.

露出し几りすることかなく成形される。When molded by blowing pressure and released from the mold after cooling and hardening, the compressed foam (2) is released from the pressure and expands, and its rle expansion is in the area corresponding to area (D). The cured molded resin (4) acts as a reaction force point toward the outside of the blower body (1), and acts as a tension on the laminate material (3), causing the laminate material (3) to swell outward and similarly. The side parts also expand laterally. The peripheral edge (2a) of the foam (2) and the edge (3a) or folded surface (5) of the laminate (3) are relatively formed into grooves (6) or grooves (6) by the expansion force.

く採用出来る。Although blow molding is a useful molding method, it is inferior to injection molding or vacuum molding in terms of the appearance and appearance of the molded product, and inner parts made of other materials are still available to compensate for this point. However, according to the present invention, blow molding can be used even when lining a foam and attaching a laminate material to the main body of the blower. The application field of blow molding has expanded greatly due to the possibility of processing, and simple methods and mold equipment for blow molding have been developed to obtain sub-quality molded products that have both tactility and elasticity after molding. As a result, foam-based laminate materials can be widely used.

第６図The figures show an embodiment of the present invention. Figure 1 is a perspective view of the seat with a foamed bilaminated material molded according to the present invention attached to the seat and back, and Figure 2 is a perspective view of the seat. mold equipment, 3rd
The figure is a cross-sectional view of one side of the mold with a foam laminate material loaded between the protrusions that protrude opposite the mold cavity, and Figure 4 shows the mold during blow molding. In cross-section on one side, the foam is shown being compressed through the parison by blowing gas pressure into the mold. FIG. 5 is a sectional view of a molded product modeled from the mold. Figure 6 shows a state in which the folded surface of the edge of the laminate material is attached halfway to the outside of the plate-like protrusion, and is an enlarged sectional view of the important part. It is a cross-sectional view of the 9g part showing the relationship between the edge and the groove, (a) shows the hole shape n where the edge is in contact with the groove and fixed by welding, and (b) shows the hole shape n where the ya iso is sandwiched in the groove. (c) shows the state where it is welded and fixed, and (c) is ya
The next state is shown after it is wrapped in the T-groove and fixed by welding. Figure 8 shows how to extend the foam to the folded surface and load the laminate into the mold. ! Figure 9 is an enlarged cross-sectional view of the main part shown in Figure 8, where the folded surface of the laminate material and the edge of the foam are sandwiched between the molded resin grooves and fixed by welding. It is a diagram. Code: 1 ・・・・・・・・・ Pro body A ・・・
