METHOD FOR PRODUCING A HOUSING OF AN AIR CONDITIONER

Abstract

A method for producing a housing of an air conditioner, in which at least a part of the housing is produced as a plastic part by means of an injection molding process by injecting a plastic into a mold cavity of an injection molding tool, wherein a damping element is placed in the injection mold prior to injection of the plastic into the injection mold so that the damping element establishes a bond with the plastic during injection of the plastic into the injection mold and becomes a component of the injection-molded plastic part.

Claims

1. A method for producing a housing of an air conditioner in which at least a part of the housing is produced as a plastic part via an injection molding process, the method comprising: injecting a plastic into a mold cavity of an injection molding tool; and placing a damping element in the injection mold prior to injection of the plastic into the injection mold so that the damping element establishes a bond with the plastic during injection of the plastic into the injection mold and becomes a component of the injection-molded plastic part.

2. The method according to claim 1, wherein the damping element is a textile damping element.

3. The method according to claim 2, wherein the textile damping element is a textile felt element, nonwoven element, or a foam element, or is a textile felt, nonwoven, and/or a foam strip.

4. The method according to claim 3, wherein the textile felt element, nonwoven element, and/or foam element is made of a plastic, a polyether, polyester, cotton, rubber, and/or of synthetic foams.

5. The method according to claim 1, wherein the placement of the damping element in the injection mold of the injection molding tool is performed automatically.

6. The method according to claim 1, wherein the placement of the damping element in the mold cavity of the injection molding tool is performed by an automated manipulator or by a robot.

7. The method according to claim 1, wherein, during the automated placement of the damping element, at least two damping elements are substantially simultaneously placed in the injection mold or wherein the placement of damping elements is carried out serially in an injection mold.

8. The method according to claim 1, wherein the bond is a chemical bond between the damping element and the plastic material.

9. The method according to claim 1, wherein the part of the housing is or has a wall part of the housing and/or is or has a flap and/or is or has a retaining frame.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein the sole figure is a schematic view of an injection molding tool of an injection molding device for the purpose of explaining the method according to the invention.

DETAILED DESCRIPTION

[0023] In a schematic representation, the figure shows an injection molding tool 1 of an injection molding device 2 for the purpose of explaining a method according to the invention for producing a housing 3 of an air conditioner.

[0024] In this case, the housing 3 is composed of at least one part that is produced as a plastic part by means of an injection molding process by injecting a plastic into a mold cavity 7 of an injection molding tool 1.

[0025] According to the invention here, a damping element 4 is placed in the mold cavity 7 of the injection molding tool 1 prior to injection of the plastic into the mold cavity 7 of the injection molding tool 1, so that the damping element 4 establishes a bond with the plastic during injection of the plastic into the injection mold 7 of the injection molding tool 1 and becomes a component of the injection-molded plastic part.

[0026] Especially advantageously, the damping element 4 is a textile damping element. In this case, the textile damping element 4 can be a textile felt element or nonwoven element, and/or a foam element, in particular a felt, nonwoven, and/or foam strip.

[0027] Preferably, the textile felt, nonwoven, and/or foam element is made of a plastic, as for example of a polyurethane, polyether, polyester, or of cotton, rubber, and/or of synthetic foams.

[0028] The placement of the damping element 4 in the mold cavity 7 of the injection molding tool 1 is accomplished in an automated fashion.

[0029] Advantageously, the placement of the damping element 4 in the mold cavity 7 of the injection molding tool 1 is accomplished by means of an automated manipulator 5 or by means of a robot 6.

[0030] During the automated placement of the damping element 4, it is also possible that multiple damping elements 4 are simultaneously placed in the mold cavity 7 and/or in the injection molding tool 1 and/or that the placement of damping elements 4 is carried out serially in the mold cavity 7 and/or in the injection molding tool 1.

[0031] In this case, the bond is a mechanical or chemical bond between the damping element and the plastic material.

[0032] Preferably, the part of the housing is a wall part of the housing or it has such a wall part and/or it is a flap or it has such a flap and/or it is a retaining frame or it has such a retaining frame, etc.

[0033] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
