METHOD OF MANUFACTURING AN ARRANGEMENT FOR THE TRANSPORT OF MEDIA AND ARRANGEMENT

Abstract

A method for manufacturing an arrangement for the transport of media includes a base body formed as a blow-molded part and at least one functional element, in which a preform consisting of polymeric material and at least one functional element are provided and arranged in a blow mold, wherein the base body is formed from the preform, wherein the preform bears against the functional element during forming, wherein the blow mold has a first mold element and a second mold element, wherein the base body is formed from the preform between the first mold element and the second mold element, wherein the first mold element and the second mold element bear against the functional element in such a way that excess material produced from the preform in the area of the functional element during blow molding can be removed.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Some embodiments of the arrangement according to the disclosure and of the method according to the disclosure will be explained in more detail below with reference to the figures. These show, each schematically:

[0021] FIG. 1 an arrangement for the transport of media;

[0022] FIG. 2 a blow mold.

DETAILED DESCRIPTION

[0023] FIG. 1 shows an arrangement 1 for the transport of media. In the present case, the arrangement 1 forms a distribution structure for temperature control media, wherein the arrangement 1 is used in a temperature control circuit of an electric vehicle. Temperature control medium can be distributed via the arrangement 1 and fed to the equipment whose temperature needs to be controlled, for example the batteries, the electric motors, or the power electronics.

[0024] The arrangement 1 comprises a base body 2, which is formed as a blow-molded part, and a plurality of functional elements 3, which are connected to the base body 2 in a loss-proof manner. In this case, the functional elements 3 are designed as connecting pieces and are used to accommodate hoses for transporting the temperature control medium.

[0025] Like the functional elements 3, the base body 2 is made of polymeric material. The functional elements 3 are produced by injection molding, wherein the plastic for the functional elements 3 is selected such that its glass transition temperature is above the temperature required for forming the base body 2 by blow molding.

[0026] Since the functional elements 3 are already arranged in the blow mold 4 during the blow molding process, the base body 2 is molded directly onto the functional elements 3 in a positive and loss-proof manner. As a result, the arrangement 1 forms a unit that is easy to assemble.

[0027] FIG. 2 shows a blow mold 4 for manufacturing the arrangement 1. The blow mold 4 comprises a first mold element 5 and a second mold element 6, wherein the base body 2 is formed from the preform between the first mold element 5 and the second mold element 6 during blow molding. In doing so, the preform is squeezed at the transition between the first mold element 5 and the second mold element 6, resulting in excess material along a seam, which is removed after the forming process.

[0028] In the area of the functional elements 3, the first mold element 5 and the second mold element 6 bear against the functional elements 3 in such a way that excess material produced in the area of the functional elements 3 during blow molding can be removed. In this case, the first mold element 5 and the second mold element 6 bear against the functional element 3 with elastic pretension during blow molding. The pretension is selected in such a way that no deformation which could result in a function restriction is introduced into the functional elements 3.

[0029] The first mold element 5 and the second mold element 6 are equipped with press-off edges 7 in the areas associated with the functional elements 3, which bear against the functional elements 3 in a linear manner and with elastic pretension during blow molding. This also forms a kind of seam in the area between the base body 2 and the functional elements 3, at which excess material can be removed particularly easily. Excess material can be cut off or torn off after blow molding. Preferably, excess material is torn off, which speeds up the manufacturing process. Depending on the embodiment, the press-off edges 7 can also form cutting edges which effect a defined separation of the base body 2 from the excess material.
