。(Prior art) For example, in the construction of molded products having a skin body,
As described in Publication No. 1-14922, a skin body is set between the cavities of a pair of opened molding molds, and a thermoplastic resin is introduced into the cavity after Q1 opening of the molding molds. Accordingly, there is a method of integrating a skin body onto the surface of a core material formed by solidifying a resin within a 4V bit.

の型閉時にキャビティからずれた周囲部分を成形金型開
で挟持するようにしている。(Problems to be Solved by the Invention) By the way, in order to prevent the skin body set in the cavity of the molding die from shifting due to the pressure of the thermoplastic resin introduced into the cavity, When the molding die is closed, the peripheral portion displaced from the cavity is held in place when the molding die is opened.

ことがある。However, when the mold is opened and the peripheral edge of the skin body is held, the skin body is stretched by the thermoplastic resin introduced into the cavity, which affects the condition of the surface of the skin body, such as wrinkles. If the surface is too strong, the skin itself may be torn, and if the skin is strong, it may not align with the cavity surface and the desired shape of the molded product may not be obtained.

になる。Therefore, from the above-mentioned JP-A-61-14922 f%taka, it is considered that before the mold is completely closed, the skin body is vacuum-sucked onto the cavity surface to make it follow the cavity shape. It is necessary to form a large number of fine slots for vacuum suction in the mold, which makes manufacturing the mold difficult and increases the R value, and also increases the number of manufacturing steps for vacuum suction.

で破れるようなこともない。Next, after the molding die 1.2 has been closed, the injection nozzle 31 is joined to the sprue 5, as shown in FIG.
The thermoplastic molten resin 32 is first filled into the cavity 3 on the back side of the skin body 21 through the sprue 5 by applying primary injection pressure. The molten resin filled into this cavity 3 is
The skin body 21 is pressed against the cavity surface 4 from the back side and joined to the back face of the skin body 21. Note that since the skin body 21 is held in a shaped state along the cavity surface 4 by the shaping body 8, the skin body 21 is not stretched due to filling with the molten resin 32, and wrinkles are less likely to occur. Further, the gas generated from the molten resin 32 acts toward the end of the straw cavity 3 in the filling direction, but since the skin body 21 at the end of the cavity 3 is held down by the shaped body 8,
It does not act directly on the skin body 21, and the skin body 21 will not be torn due to the influence of the gas.

Secondary injection pressure (holding pressure)
multiply. As a result, the Kirebity 3 where the shaped body 8 was located
The molten resin 32 is filled up to the end of the cavity 3, and the molten resin 32 is reliably filled into the interior of the cavity 3. Note that the gas generated from the molten resin 32 is transferred to the mold 8 and the mold 2.
It escapes to the outside through the space between.
その後、溶融樹脂３２の温度低下に伴って固化して芯材
３３が成形され、芯材３３の表面に表皮体２１を一体止

る成形品の製造方法。(1) A skin body is set in the cavities of a pair of molds that have been opened, and after the molds are closed, a synthetic resin is introduced into the cavity to form a core material integrally with the skin body. In the method for manufacturing a molded product having a body, when the molding molds are closed, a shaped body that can move forward and backward from the cavity surface of one molding mold toward the cavity surface of the other molding mold is protruded. A method for producing a molded article having a skin body, characterized in that when the mold is closed, the skin body is shaped by a shaping body so as to follow the shape of the cavity surface of the other mold.
