Description
Bei Werkzeugen zum Pressen von Kunstharzpreßteilen hat man es oft als einen großen Mangel empfunden, daß zwischen den Stiften, Bolzen oder Werkzeugteilen, die zur Erzeugung von Löchern oder Durchbrechungen dienen, Rückstände von Preßmasse verbleiben, die an den fertigen Preßlingen nachträglich entfernt werden müssen. It is often the case with tools for pressing synthetic resin molded parts perceived as a great deficiency that between the pins, bolts or tool parts, which are used to create holes or perforations, residues of molding compound remain, which must be subsequently removed from the finished compacts.
Durch den Gegenstand der Erfindung soll dieser Mißstand beseitigt werden, und zwar besteht die Erfindung darin, daß die stifte, Bolzen oder Werkzeugteile stark federnd ausgebildet sind und mit starkem Federdruck gegen ihre Abstützflächen drücken. Dadurch wird die überschüssige Preßmasse während des Fließvorganges restlos weggedruckt und eine Gratbildung vermieden. The object of the invention is intended to remedy this deficiency be, namely the invention consists in that the pins, bolts or tool parts are designed to be highly resilient and with strong spring pressure against their support surfaces to press. As a result, the excess molding compound is completely removed during the flow process printed away and avoiding burrs.
In der Abbildung ist ein Werkzeug im Schnitt beispielsweise dargestellt. For example, a tool is shown in section in the illustration.
Die beiden Bolzen 1 und 2, die entsprechende Löcher in dem Preßling 3 formen, stehen unter dem Druck der Feder 4 und werden von dieser nach oben gegen den Stempfel 5 des Werkzeuges gedrückt. The two bolts 1 and 2, the corresponding holes in the compact 3 form, are under the pressure of the spring 4 and are up against it by this pressed the plunger 5 of the tool.
Wenn zwischen dem Stempel 5 und den Bolzen 1 und 2 infolge des Füllvorganges noch Rückstände von Preßmasse verbleiben, so werden diese durch den Druck der Feder 3, sobald die Masse zu fließen beginnt, restlos weggedrückt. Die beiden Bolzen 1 und 2 setzeil sich schließend auf den Steml)el 5 auf, ohne daß Massenrückstände zwischen diesen Teilen zurückbleiben.If between the punch 5 and the bolts 1 and 2 as a result of the filling process or residues of molding compound remain, these are removed by the pressure of the spring 3, as soon as the mass begins to flow, pushed away completely. The two bolts 1 and 2 sits on top of the stem 5 without leaving any residue remain between these parts.
Ebenso wie die Bolzen 1 und 2 können im Sinne der Erfindung auch andere Werkzeugteile federnd ausgebildet sein, wenn bei ihnen Gefahr besteht, daß sich an diesen ein Grat bilden kann. As well as the bolts 1 and 2, in the context of the invention other tool parts be resilient if there is a risk that they a ridge can form on these.
