When the glass fiber material R is used as an original fabric, it is usually formed into a mat-like shape (for example, a thickness of about 3.5 mm) by being entangled to a design density as shown in FIG. The thermoplastic resin powder P or pellet for the binder is mixed so as to be uniform. This mat-shaped raw fabric A1 is pressure-treated into a sheet (for example, a thickness of about 0.8 mm) by using a press 1 including upper and lower molds 1a and 1b as shown in FIGS. Then, it is processed into a sheet-shaped original fabric A2. After that, the sheet-shaped original A2 is shown in FIG.
As shown in, the blank is cut into a size corresponding to the size of the product.

In such a conventional manufacturing method as described above, the mat-shaped original fabric A1 is pressure-treated to form the sheet-shaped original fabric A2 by the time the shape forming die 4 is reached. Since the heating means 3 has to be used to heat to a predetermined temperature, there is a problem that the number of processing steps is increasing. Also, the clamped and molded glass fiber product A4,
Since a method is adopted in which the mold is taken out from the mold 4 after being cooled to a temperature at which it is not deformed even if taken out from the mold 4, when continuously molding with the same mold, it is cooled to a predetermined temperature in the mold. There was a problem that it took time and productivity was poor. In addition, since the temperature setting at the time of taking out is close to the limit temperature in terms of efficiency, it is not uncommon for deformation or the like to occur due to vibration applied during the taking out process.

According to the present invention as described above, even when the raw material is a glass fiber material mixed with a thermoplastic resin for a binder, a mold capable of directly thermoforming the raw material like a thermosetting resin. The purpose is to reduce the number of processes by performing mold clamping and molding. Specifically, it is premised that a mold that can be heat-molded is used, and the original fabric has not been pressure-processed into a sheet shape in advance as in the past, and the original form has not been clamped. Even if it is not hardened (not cooled below the temperature that does not deform), by taking it out from the mold together with the auxiliary metal plate, keep the shape by the auxiliary metal plate even after it is taken out. It was made possible. Therefore, the shape is not deformed even if it is taken out immediately after the die is clamped, which makes it possible to shorten the time from die clamping to take-out, and to operate the same die efficiently. It is possible.

Therefore, according to this embodiment, the mat-shaped raw fabric B1 is not preliminarily pressed and formed into a sheet shape as in the prior art, but the thermosetting resin is immediately heated and pressed to mold it. can do. Moreover, since the glass fiber product B2 in the mold 5 can be taken out while being held and held on the auxiliary metal plate 6 after the mold clamping by the heat moldable mold 5, the mold clamping molding is performed. It is possible to shorten the time from the removal to the removal and improve the productivity. Also, glass fiber products B2
After being taken out from the mold 5, it can be sufficiently cooled on the auxiliary metal plate 6 and then separated, so that deformation and the like can be suppressed when separating, and the yield can be improved.

As described above, according to the manufacturing method of the present invention, even if the original fabric is in the original form in which the glass fiber is mixed with the thermoplastic resin, the mold is heated and clamp-molded at the same time. Even if the textile product is not yet cured (not cooled to a temperature that does not cause deformation), take it out from the mold together with the auxiliary metal plate, and the shape is retained by the auxiliary metal plate even after it is taken out. Since this is done, first, it is possible to omit the conventional step of pressing the raw fabric into a sheet. In addition, since the shape does not change even if it is taken out immediately after mold clamping with a heat-moldable mold, it is possible to shorten the time from mold clamping to removal and improve the productivity. By using a large number of auxiliary metal plates, it is possible to operate the same metal mold with high efficiency. Therefore, if the glass fiber product molded in the auxiliary mold is cooled sufficiently after being taken out from the mold, deformation and the like at the time of taking out can be suppressed and the yield can be improved.
