という欠点もあった。The slush molding method is a conventional method for producing composite resin molded products.The slush molding method is roughly divided into a skin molding process and a foam layer molding process.First, the skin molding process is A mold for molding the skin is heated, and vinyl chloride paste and powder are placed in the mold. Next, the mold is rotated or rocked to solidify the vinyl chloride solution while adhering it to the cavity surface of the mold to a substantially uniform thickness, thereby forming a vinyl chloride layer on the cavity surface. Next, the mold is cooled, and the vinyl chloride layer is released from the mold to form a skin. Next, this skin is set in a separately prepared foaming mold, and the core mold is combined with this foaming mold and the mold is clamped. Next, foamable urethane is injected into the cavity formed by the foam mold and the core mold, and this is foamed again to form a foam layer that is integrated with the skin, and then this is released from the mold to form a product. However, this slush molding method involves a skin molding process and a skin molding process in which the skin obtained by this skin molding process is placed in a foam mold.
L, which forms a foam f- that is integral with its epidermis.
The molding process is complicated because a culm is required.
Moreover, since two types of molds, a skin molding mold and a urethane foaming mold, are required, there are problems in terms of equipment, and in history, there have also been problems in terms of product cost. Historically, it has been difficult to shorten the heating and cooling of the mold during the skin molding process and the foaming time after the foaming urethane injection process, resulting in low productivity.

しめることである。This invention was developed in light of the inception of the present invention, and its first purpose is to simplify the equipment and significantly shorten the molding process time by using a mold for molding the skin and a mold for molding the foam layer. It is to measure the shortening. The second purpose is to use expandable vinyl chloride instead of the conventional foaming of urethane resin to significantly shorten the flow rate during the foaming process, and to improve the adhesion between the skin material 1- and the foam layer. The goal is to improve the quality of products.

る表皮２′を形成する（第４図参照）。1 is a cavity mold heated to 200 DEG C. to 300 DEG C. First, an appropriate amount of paste or powder vinyl chloride 2 is poured into the cavity mold 1 by two people. Next, a lid 3 is placed on the opening of this cavity mold 1, and the above-mentioned vinyl chloride 2 is deposited on the mold surface of the cavity mold to a uniform thickness by swinging or rotating the cavity mold 1, and then This cavity mold 1 is immersed in a water bath to cool it, and a skin 2' made of vinyl chloride having a uniform thickness is formed on the mold surface of the cavity mold 1 (see FIG. 4).

できる。Next, a paste-like or powder-like foamable vinyl chloride 4 mixed with an appropriate amount of a foaming agent is placed on the skin 2' in the cavity mold 1, and then a base material assembly metal fitting 6 is set in advance. The core mold 5 is assembled into the cavity mold 1, and then both molds, that is, the cavity mold 1 and the core mold 5, are heated and placed in the cavity. The foamable vinyl chloride 4 is foamed to form a foam layer 4' that is integrated with the skin 2' (see Figure 7).The molds are then cooled and the finished product is released from the mold to form the skin 2'. It is possible to form a product in which the foam layer 4 and the foam layer 4' are integrated and the metal fitting 6 for assembling the base material is inserted, that is, the desired composite side 1f)i'' molded product.

価値の犬なる製品を生産することもできる特長がある。As described above, in the present invention, vinyl chloride paste and powder are put into a heated cavity mold 1, and after making the thickness uniform, the cavity mold 1 is cooled to form a skin 2' of vinyl chloride resin. Then, after placing chlorinated beer paste and powder mixed with a blowing agent on the skin 2',
This is a method for manufacturing a composite resin molded product, which is characterized by clamping the mold with a bow-shaped mold 5, and then heating both the cavity mold 1 and the core mold 5 to form a foam layer 4' that is integrated with the skin. Since the product produced by this manufacturing method has the same quality of vinyl chloride as the skin 2' and the foamed no. . Furthermore, since the molds for forming the skin 2' and the foam layer 4' can be jointly molded using a set of molds, the molding stage 116 including the molds can be simplified, and the molding process can be simplified accordingly. Further, according to the present invention, by forming, for example, an uneven pattern on the mold surface of the cavity mold, a clear pattern corresponding to the uneven pattern is formed on the surface of the skin layer 6. It has the advantage that it is possible to produce dog products with commercial value as well as benefits.
