[Problems to be Solved by the Invention] However, since the above-mentioned stay is molded using a mold that is separate from the mold that molds the panel body, there is a problem that increases the cost of manufacturing the parts. In addition, there was a problem in that the panel body and the stay had to be managed separately, making parts management cumbersome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a molded article for an instrument panel that can reduce the number of molds and facilitate the construction work of stays for mounting instruments and the management of parts.

[0005]

[Means for Solving the Problems] The structure of the present invention for achieving the above object will be explained using FIGS. 1 and 3, which correspond to embodiments. The present invention has a fixed mold 15 and a movable mold 1.
After the resin material is injected into the cavity 17 formed when the molds 6 are joined together and closed and cured, the movable mold 16
This is an improvement of a molded body for an instrument panel in which a panel body 12 having an opening 12a is formed by sliding it open, and instruments 18 are mounted on stays 13 and 14 installed in the opening 12a. Its characteristic structure is that the stays 13 and 14 are connected to the movable mold 1 near the installation position.
It is molded integrally with the panel body 12 together with the connecting members 19, 21 that connect to the panel body 12 at the slidable position of 6, and has a length that allows the molded connecting members 19, 21 to move the stays 13, 14 to the erection position. It is characterized by its flexibility and flexibility.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 3, the molded body 11 for a vehicle instrument panel includes a panel body 12 having an opening 12a, and two stays 13 and 14 installed in the opening 12a. The panel body 12 is molded by injecting a resin material into a cavity 17 formed in a fixed mold 15 and a movable mold 16 that are joined together and closed, and then hardened. Moreover, the movable mold 16 is provided so as to be slidable in the direction of the solid arrow (FIG. 3).

The upper edge of the opening 12a has instruments 1 to be described later.
A protruding upper part 12b covering the upper surface of the instrument 18 is provided integrally with the panel main body 12, and a protruding lower part 12c close to the bottom surface of the instruments 18 is provided integrally with the panel main body 12 at the lower edge of the opening 12a. The lower surface of the protruding upper part 12b and the protruding lower part 12
Attachment bosses 12d,
12e is provided integrally with the panel body 12, and the mounting bosses 12d, 12e have screw holes 12f, 12h into which screws 24, 24 can be screwed, and positioning pins 12g, 12.
i is formed (Figure 2). Two through holes 13a, 13b, 13c, and
13d is formed. In FIG. 1, only the parts related to the stay 13 are labeled with reference numerals to avoid complexity. One of the through holes 13a, 13b is formed to be able to fit into the positioning pins 12g, 12i, and the other through hole 13c, 13d is formed into the screw hole 12f when the one through hole 13a, 13b is fitted into the positioning pin 12g, 12i. , 12h. A boss 13e is integrally provided approximately in the center of the two stays 13, 14, and a screw 26 is attached to the boss 13e.
A screw hole 13f is formed into which the screw hole 13f can be screwed. Opening 12a
Instruments 1 are installed between the two stays 13 and 14 installed on the
A through hole 18b is formed in the tightening portions 18a protruding from both sides of the instruments 18 (FIGS. 1 and 2).

The characteristic configuration of this embodiment is that the two stays 13 and 14 are connected to the panel body 12 at slidable positions of the movable mold 16 near their respective erection positions. Molded integrally with 12,
The connecting members 19, 21 after molding are moved to the installation position by the stays 13,
It has the length and flexibility to move 14. The two stays 13 and 14 are connected to the protruding lower part 12c of the panel body 12 that forms the lower edge of the opening 12a by connecting members 19 and 21 and auxiliary connecting members 22 and 23, respectively (
Figure 1).

The panel body 12 and stays 13, 1 of the instrument panel molded body 11 constructed as described above
4 injects a resin material into the closed fixed mold 15 and the cavity 17 of the movable mold 16 and hardens it, and then the movable mold 1
6 in the direction of the solid line arrow in FIG. Cut the auxiliary connecting members 22 and 23 of the two stays 13 and 14, and move the stays 13 and 14 connected by the connecting members 19 and 21 to the installation position of the opening 12a shown by the two-dot chain line in FIG. let One of the through holes 13a, 13b of the stays 13, 14 is connected to the positioning pins 12g, 12.
The stays 13, 14 are fixed at the installation position of the opening 12a by screwing the screws 24, 24 inserted into the holes 12f, 12h into the screw holes 12f, 12h (FIG. 2). . As a result, a separate mold for molding only the stays 13 and 14 is not required, so the number of molds can be reduced. Also, the stays 13 and 14 are always connected to the panel body 12.
Since the stays 13 and 14 can be easily installed in the opening 12a of the panel body 12, there is no need to manage the parts of the stays 13 and 14. The opening 12a is fixed by the two stays 13 and 14 installed in the opening 12a.
In addition, by inserting the instruments 18 between the two stays 13 and 14, the through hole 18b of the tightening part 18a can be reinforced.
The instruments 18 are attached to the stays 13 and 14 by screwing the screw 26 inserted into the screw hole 13f.

In the embodiment, two stays are installed in the opening, but this is just an example, and one or more stays may be installed in the opening. Further, in the embodiment, the stay is connected to the panel main body by the connecting member and the auxiliary connecting member, but the stay is not limited to this, and may be connected only by the connecting member without using the auxiliary connecting member.

0012

As described above, according to the present invention, a molded article for an instrument panel includes an injection-molded panel body having an opening, and a stay installed in the opening to which instruments are attached. , the stay is molded integrally with the panel body together with a connecting member that connects to the panel body at a slidable position of the movable mold near the erection position, and the length that allows the molded connecting member to move the stay to the erection position. Since it has flexibility, a separate mold for molding only the stay is not required, and the number of molds can be reduced. As a result, the cost of manufacturing parts can be reduced. Also, when installing the stay, there is no need to accidentally drop the stay, and the stay can be installed in the opening by simply moving the stay a small distance.
Erection work of the stay becomes easier. Furthermore, since there is no need to manage the stay as a component, component management can be facilitated.
