Abstract
A method of producing rubber/metal components is provided. The rubber is injected into a mold chamber that contains the metal part, and the rubber is cured (vulcanized) in this mold chamber. The mold chamber also serves for the forming of the metal part, which remains in its mold chamber for the forming of the rubber.
Description
METHOD OF PRODUCING RUBBER/METAL COMPONENTS
Background of The Invention The present invention relates to a method of producing rubber/metal components.
Within the context of the instant application, the term "rubber"
designates not only natural and synthetic rubber, but also elastomeric polymeric materials, such as TPE (thermoplastic elastomers). In addition, within the context of the present invention rubber/metal components are such components where the rubber is frictionally and/or positively, preferably however adhesively, connected with the metal part.
Such components generally have a metal part because the latter serves for the fastening and/or the securement of the component. Thus, for example, it is possible to use such a component for, for example, seals, vibration dampeners, reinforced profiled members, bellows, etc.
Pursuant to heretofore known methods, in order to produce such a rubber/metal component, the metal part is first separately manufactured, for example by stamping, bending, or by machining steps.
The thus-produced elements are generally supplied to the rubber processors, which in turn generally utilize the metal part as an insert for a mold cavity or chamber in order to then form the rubber and thereby also effect a connection to the metal part.
Aside from the fact that with this known process not inconsiderable problems with logistics can result, prior to being inserted into the mold DE 199 38 015.5 of 11 August 1999 - Canada chamber the metal parts must be prepared, for example by deburing and degreasing.
It is therefore an object of the present invention to avoid the aforementioned drawbacks. A method is desired that enables a common production of the constituents of the component and their combination.
Brief Description of the Drawing This object, and other objects and advantages of the present invention, will appear more clearly from the following specification in conjunction with the accompanying schematic drawing, in which:
Fig. 1 is a vertical cross-sectional view, in the starting position, of one exemplary embodiment of an inventive tool for producing rubber/metal components, for example a bumper, as a sequencing tool; and Fig. 2 - 4 each illustrate the tool of Fig. 1, but in different process steps.
Summary of The Invention The method of the present invention is characterized primarily in that the mold cavity or chamber that is used for producing the rubber part is also used for forming the metal part, which remains in its mold chamber for the forming of the rubber or rubber-like polymeric material. Thus, the metal part is formed in the mold chamber in which later, in order to DE 199 38 015.5 of 11 August 1999 - Canada complete a component, the rubber is formed and is also cured, which within the context of the present invention refers to hardening or setting of the material, for example in the case of a thermoplastic elastomer, or vulcanizing of the material, as appropriate. In this connection, to form the rubber, and to form the metal part, the injection molding process is expediently relied upon because it ensures a rapid and true to form manufacture.
The inventive method also leads to the recovery of heat. This is in particular the case if the two injection processes follow one another closely in time in such a way that the heat for vulcanization is applied at least partially from the cooling off of the metal part. For this reason, it is also advantageous to utilize so-called sequencing tools, in other words to utilize mold chambers that are disposed, for example, in a carousel-like manner and that ensure a rapid sequence of operation of the two injection processes.
In order to preclude operational steps between the two injection processes, it is advantageous to add adhesive to the elastomer that is to be injected if the elastomeric material is to be adhesively secured to the metal part.
To carry out the inventive process, metallic alloys are particularly suitable where at ambient temperatures they have dendritic structures, and when heated up have a semi-solid aggregate state with thixotropic DE 199 38 015.5 of 11 August 1999 - Canada properties. Alloys of this type can contain: approximately 90-95% Mg, approximately 5-9% AI, as well as Zn, Mn, Si, Cu, Ni, Fe, and the like, respectively in concentrations below about 1 %.
Further specific features of the present invention will be described in detail subsequently.
Description of Preferred Embodiments Referring now to the drawing in detail, the lower portion 1 of the tool or die is pivotable about its central axis 2 in respective steps of 180°.
At diametrically opposed locations the lower portion 1 is provided with mold cavities or chambers 3, 4, each of which has associated therewith an upper portion 5 as a cover, with the two upper portions having different penetration depths into the mold chambers. In addition, the upper portions 5 are provided with funnels 6 having feed bores 7 for the injection of material. The pivotable mounting of the lower portion 1 and the mechanisms for closing off the mold chambers 3, 4 have not been illustrated. Such devices and mechanisms can have any desired conventional configuration. The lower portion 1 is furthermore provided with ejectors 8 for the finished workpieces.
The article, for example a bumper, that is to be produced comprises a lower metal plate 9 having two downwardly extending legs 10 for the mechanical securement of the bumper, for example on a frame;
the article furthermore comprises a rubber plate 11 that is fixedly, for DE 199 38 015.5 of 11 August 1999 - Canada example adhesively, disposed on the metal plate 9.
In the starting position of the tool shown in Fig. 1, it is presumed that the metal component in the form of the metal plate with the legs 10 has already been introduced into the mold cavity 3.
Pursuant to Fig. 2, a rubber to which has been added an adhesive is now injected into the mold chamber 3 to form the plate 11. The injection process is followed by vulcanization. At the same time as the injection of the rubber, there is introduced into the mold cavity 4 the following still specified metal alloy with the aid of a 2-K injection machine to form the metal plate 9 having the legs 10. In so doing, heat flows to the mold cavity 3, thereby enhancing the vulcanization process.
As show in Fig. 3, after conclusion of the vulcanization the finished rubber/metal component, after raising the cover 5, is ejected in the direction of the arrows 12. At the same time, the cover 5 of the mold chamber 4 is also raised.
;the lower portion 1 is then pivoted into the position shown in Fig.
4, and after the mold chambers 3, 4 are closed the starting position shown in Fig. 1 is again achieved.
In this connection, it is important that the covers 5, which penetrate to different depths, do not follow the pivoting of the lower portion 1.
Although the method of the present invention is, in principle, not bound to specific materials, nonetheless the metal part 9, 10 is preferably DE 199 38 015.5 of 11 August 1999 - Canada H
produced as a magnesium base via the "Thixo-molding" process from a magnesium alloy utilizing the injection molding or die-casting process.
Particularly suitable for this purpose is an alloy comprising approximately 90% Mg, 9% AI and approximately 1 % Zn. This alloy has a solidus temperature of about 465° C, and a liquidus temperature of about 596°
C, as well as a desired temperature range of about 580-590°C for the processing. During injection of the alloy, the tool or die has a temperature of about 200-250°C. In contrast, the vulcanization temperatures for rubber elastic material is about 160-190°C.
It should be noted that with the tool shown in the drawing, the mold chamber sequence is effected by a pivoting movement of the tool about a preferably vertical axis. However, it is to be understood that other sequence constructions, for example via a linear movement of the tool, are also possible, whereby also in such a situation it is expedient to provide a temperature influence of the mold chambers in the manner previously discussed.
The specification incorporates by reference the disclosure of German priority document 199 38 015.5 of 11 August, 1999.
The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawing, but also encompasses any modifications within the scope of the appended claims.
