あった。Blow molding has been widely used as a method for producing hollow bodies. This is a method of producing a hollow body by extruding a thermoplastic resin parison between split molds having a cavity surface formed in a desired three-dimensional shape and clamping the mold while blowing air into the parison. there were. In this case, in order to use the obtained hollow body in an automobile interior material such as an automobile sun visor, it is necessary to improve the design of the surface of the molded body, and the surface of the hollow molded body has a surface material (having a softer feel than the molded body). A resin sheet or fabric) was attached. It is preferable that this sticking is carried out at the same time when the hollow molded article is manufactured, because the number of steps is reduced, but it is technically difficult and the sticking cannot be done easily in some cases. In particular, when the cover material is a non-breathable material such as a resin sheet, there is a serious problem that air is trapped between the parison and the cover material and flutters on the surface of the molded product.

方法にある。Means for Solving the Problem The means for solving the problem is to provide a thermoplastic resin which is in a plastic state in the opened state of a split mold having a cavity surface formed in a desired three-dimensional shape. A parison is extruded, and a surface-mounted resin sheet with a large number of minute holes is placed between the parison and the cavity surface of the molding die. When the mold is clamped, air is blown into the thermoplastic resin parison to cover the parison. The sheet is pressed against the sheet. At this time, the air trapped between the parison and the cover resin sheet is squeezed out from the minute holes of the cover resin sheet to the outside, and the parison and the cover resin sheet are further pressed against the cavity surface of the mold to weld the ends. This is a method for producing a hollow body in which the inside is made hollow.

Since air leaks out from the minute holes of the surface-mounted resin sheet to the outside, air is not trapped between the parison and the surface-mounted resin sheet to prevent fluttering on the surface of the molded product. In particular, by adjusting the size and density of the micropores in relation to the air blowing pressure, the hollow body can be manufactured in a state in which the micropores are not conspicuous on the surface of the surface-mounted resin sheet and the designability is maintained.

A male and female molding die 11 is clamped with a cavity 15 corresponding to the outer shape of the desired hollow body.
In the initial stage, the molding dies 10 and 11 are left open, the parison 30 of the thermoplastic resin is extruded and hung down between them, and two covering resin sheets 60 and 61 are stretched between the parison and the molding die. To do. (A) The thermoplastic resin parison 30 is preferably made of polyethylene resin or polypropylene resin, and is heated in a plastic state and extruded from a circle die or the like by a known extruder (not shown) and has a thickness of 0. It is about 5 to 3.0 mm. As for the viscosity of the resin used here, it is suitable that the 190 ° C. melt flow rate (JIS-K-7210) is 0.2 or more and 3.0 or less (190 ° C., 2.16 kgf). This is because the temperature of the resin when the parison resin extruded from the extruder is drooped between the molding dies 10 and 11 at the time of molding becomes approximately 190 to 200 ° C. Therefore, if the resin flowability at this temperature is high. If it is too large, the drawdown of the parison becomes large and the wall thickness may become uneven or wrinkles may occur. If the flowability of the resin is too low, the parison is difficult to stretch and the moldability is reduced, and the fusion force between the base materials is reduced, which makes terminal treatment difficult, and the simultaneous adhesiveness with molding of the cover resin sheet is also reduced. Resulting in. The cover resin sheets 60 and 61 are
Those having a softer feel than the parison resin and having appropriate stretchability are preferable, thermoplastic elastomers (olefin-based and ester-based) are most suitable, and vinyl chloride resins and foam-backed ones are also preferable. The size of the cover resin sheet is large enough to cover the parison,
A suitable thickness is about 0.2 to 2.0 mm. In addition to the method of arranging the two cover resin sheets 60 and 61 on the left and right,
There is also an arrangement in which one resin sheet is folded back and a parison is sandwiched between them. These are arranged so that the seams of the cover resin sheet will be inconspicuous in consideration of the appearance when the hollow body is finally made into a product. It is also possible to arrange the parison with a cylindrical cover sheet. The covering resin sheet is preferably arranged by applying an appropriate tension between the molding dies, but in some cases it is also preferable to preheat it before stretching it between the molding dies to enhance flexibility and facilitate molding. is there. A large number of pinholes are formed in the surface resin sheet. This is suitable to be formed by roll or punching by needle hole processing.
Suitably the diameter of the micropores is 0.01 to 0.5 mm. When the pore diameter is 0.5 mm or more, the traces of pores are conspicuous on the surface of the surface-mounted resin sheet, which impairs the designability, and may be broken by the molding tension. The pore size is 0.01
If it is less than mm, the efficiency of air discharge becomes poor, and air may remain between the parison and the cover resin sheet, resulting in defective appearance such as pockmarks. The formation of the micropores is more stable if the micropores are evenly spread over the entire surface of the covering resin sheet.
It is preferable that the surface of the cover resin sheet (the surface in contact with the mold cavity surface) is provided with a squeeze pattern so that the traces of the micropores are less noticeable. Further, a non-woven fabric or the like can be applied to the back surface (the surface in contact with the parison) to improve the sticking effect when the fluff of the non-woven fabric enters the parison. Next, the thermoplastic resin parison 30 and the cover resin sheet 6
Air blow nozzle 4 when 0 and 61 are placed between the molds
0 is introduced from below (b). This air blowing nozzle is connected to a blowing device (not shown) to supply air. When the introduction of the air blowing nozzle is completed, air blowing is started and the mold is clamped at the same time to form a hollow inside of the parison. At this time, when the parison expands and is pressed toward the cover resin sheet, an air pool 20 is partially generated between the parison and the cover resin sheet. It is discharged to the outside (the arrow in the figure shows the flow of air). This discharge depends on the expansion pressure of the parison in the direction of the cover resin sheet, but more reliable discharge can be performed by forming the mold with a vacuum structure and performing blow vacuum simultaneous molding. Further, when the mold clamping and the introduction of air are continued, finally the air in the air reservoir 20 is completely discharged, and the parison resin and the covering resin sheet are closely laminated and pressed against the cavity surface to form a desired three-dimensional shape. (C) Air pressure is 3.0 kg / cm 2 or more, 10.0 kg
/ Cm 2 or less is preferable. This is determined by the relationship with the melt flow rate of the parison resin, but by setting the air pressure to 3.0 kg / cm 2 or more, the parison is pressed against the cavity surface 13 of the mold and the contour of the sun visor. However, if the pressure is set to 10.0 kg / cm 2 or more, the molding becomes abrupt and a part of the parison is suddenly stretched to be thinned or broken. After the molding of the resin is completed, the mold is opened and the end is trimmed by a known method (knife cut, pinch-off).
Is obtained. In the above embodiments, the blow molding was explained using the parison, but it is also possible to modify it by replacing it with two thermoplastic resin sheets. In addition to blow molding, it is also possible to use a vacuum molding die structure for the molding die and perform blow vacuum simultaneous molding.
