Description
Beim Verarbeiten von härtbaren Kunstharzpreßmassen ist es bekannt, die Kunstharzmassen vor dem Pressen vorzuwärmen. Um dies zu erreichen, wird im allgemeinen die vorzugsweise zu Tabletten vorgepreßte Masse in besondere Vorwär.möfen gelegt und nach Erreichung einer gewissen Plastizität in die Preßform gebracht. When processing curable synthetic resin molding compounds, it is known to preheat the synthetic resin masses before pressing. To achieve this, in general the mass, which is preferably pre-pressed into tablets, is placed in special preheating ovens and brought into the mold after a certain plasticity has been achieved.
Gemäß der Erfindung wird das Vorwärmen von Kunstharzpreßmasse dadurch verbessert, daß die Wärme der Preßform zum Vorwärmen der Kunstharzpreßmassen ausgenutzt wird. Zweckmäßigerweise verwendet man den Raum unmittelbar unter der Preßform als Vorwärmkammer. So ist es z. B. möglich, unterhalb der Preßform einen Durchlaufschacht vorzusehen, in welchem die Kunstharztabletten vorgewärmt werden. Das Erwärmen der Kunstharzpreßmasse kann auch in besonderen unter der Preßform angeorclneten Einlagekästen erfolgen. According to the invention, the preheating of synthetic resin molding compound is thereby improved that the heat of the mold used to preheat the Kunstharzpreßmassen will. Appropriately, you use the space immediately under the mold as Preheating chamber. So it is B. possible, a passage shaft below the mold to provide in which the synthetic resin tablets are preheated. Warming the Synthetic resin molding compound can also be placed in special insert boxes arranged under the mold take place.
In der Figur ist die Erfindung an Hand einer Skizze näher veranschaulicht. Unterhalb der Preßform I ist mit Hilfe des Blechmantels 2 eine Vorwärmkammer gebildet, durch welche ein Durchlaufschacht 3 führt, worin die Kunstharztabletten 4 erwärmt werden. Bei 5 erfolgt der Einfall der Tabletten, diese werden dann unterhalb der Pre8-form I hindurch durch den Schacht 3 fallen bei 6 vorerwärmt heraus. In the figure, the invention is illustrated in more detail using a sketch. Below the mold I a preheating chamber is formed with the help of the sheet metal jacket 2, through which a duct 3 leads, in which the synthetic resin tablets 4 are heated will. At 5 the tablets collapse, they are then below the Pre8-form I through the shaft 3 fall out at 6 preheated.
