Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel such as a suction grill of a wall-mounted indoor unit in a separation type air conditioner.

[0002]

[Prior Art]

 FIG. 3 shows an example of a wall-mounted indoor unit. In FIG. 3, 1 is a suction grille, 2 is a front case, 10 is a case body, 11 is a heat exchanger, and 12 is a fan. The pin shaft 7 provided at the tip of the arm 4 projecting from the back surface of the suction grill 1 is fitted into the pin hole formed in the bracket 3 fixed to the front case 2, and the suction grill 1 has the pin shaft 7. It is supported by the front case 2 so as to be rotatable around it. Reference numeral 6 is a fixing latch for keeping the suction grill 1 closed. When the air conditioner is in operation, the air that has flowed in through the suction grill 1 is cooled or heated by passing through the heat exchanger 11, is energized by the fan 12, and then is blown from the outlet 13 by the vertical louver 15. And it is blown out indoors by being guided by the horizontal louver 14.

As shown in the enlarged view of FIG. 2, the suction grill 1 has a bent portion 16 formed by bending the upper edge of the suction grill 1 rearward. The arm 4 is provided so as to project in the vicinity of the bent portion 16 and extends rearward, and its tip is bent upward toward the bent portion 16. A pin shaft 7 is provided on one side surface of the tip of the arm 4 so as to be orthogonal thereto. The suction grille 1 is integrally molded by injection molding of synthetic resin, but since a so-called undercut portion 17 shown by hatching is formed between the bent portion 16 and the arm 4, this undercut is made during injection molding. Injection molding is performed using a molding die that has a slide die that is disposed in the portion 17 and that slides when the molded article after molding is taken out from the molding die.

[0004]

[Problems to be solved by the device]

 In the above conventional structure, as shown in FIG. 2 (B), the distance a between the tip of the pin shaft 7 and the side surface of the arm 4 opposite to the side surface on which the pin shaft 7 is projecting is large. However, the slide mold also needs a large one that can move this distance a, so that there is a problem that the mold becomes large and the cost increases.

[0005]

[Means for Solving the Problems]

 The present invention has been proposed to solve the above problems, and its gist is to provide a bent portion formed by bending an end edge and a bending direction in the vicinity of the bent portion in the bending direction. A forming die having a slide die is provided, which includes an arm that is projected and the tip of which is bent toward the bent portion, and a pin shaft that is projected on one side surface of the tip of the arm and extends in a direction orthogonal to the arm. In a panel of an air conditioner that is integrally molded by injection molding of synthetic resin using a cutout part that reduces the thickness in the pin axial direction on the side opposite to the side where the pin shaft is provided at the tip of the arm It is on the panel of the air conditioner, which is characterized by

[0006]

[Action]

 In the present invention, since the slide die has a small amount of movement because it has the above-described structure, and therefore the slide die becomes small, the molding die is small and inexpensive.

[0007]

【Example】

 One embodiment of the present invention is shown in FIG. As shown in FIG. 1, a cutout portion 20 is formed on the side surface 4b at the tip of the arm 4 opposite to the side surface 4a on which the pin shaft 7 is provided so as to reduce the thickness in the direction of the pin shaft 7. There is. The notch 20 is formed at a portion corresponding to the bent portion at the tip of the arm 4, that is, at a portion above the upper surface of the base of the arm 4. The depth of the notch 20 is preferably as deep as possible unless the strength of the arm 4 is insufficient.

A slide die is installed in the undercut portion 17 during injection molding of the suction grill 1, but the distance b between the tip of the pin shaft 7 and the bottom surface of the cutout portion 20 becomes short. By moving the slide mold by the distance b, the upper mold and the lower mold can be separated and the molded product can be taken out. The present invention can be widely applied not only to the suction grill 1 but also to the panels of the front case 2, the case body 10 and the like.

[0009]

[Effect of the device]

 In the present invention, since the notch for thinning the thickness in the axial direction of the pin is provided on the side opposite to the side where the pin shaft projects from the tip of the arm, the slide type movement is small, which is sufficient. Therefore, since the slide die becomes smaller, the molding die becomes smaller and less expensive.
