Der Gegenstand der Erfindung betrifft die Erzielung einer gleichmäfsigen Pressung des Formsandes im Formkasten über dem Modell bei Formmaschinen jeder Art.The object of the invention relates to achieving a uniform pressing of the Molding sand in the molding box above the model in molding machines of all kinds.
Man erreicht dies dadurch, dafs man der Platte, mit welcher man den Sand prefst, die negative Form des Modelies giebt. Man mufs also für jede Formplatte eine besondere Druckplatte anfertigen, besonders bei sehr hohen Modellen. Vorliegende Erfindung gestattet nun, ohne Auswechselung von Druckplatten, dem Former, in kurzer Zeit sich eine Prefsvorrichtung herzustellen, welche genau die negative Form des Modelies oder mehrerer auf einer Platte befestigten Modelle besitzt.This is achieved by placing the plate with which one prefers the sand gives negative form of the model. So you have to have a special pressure plate for each mold plate make, especially for very tall models. The present invention now allows without changing the printing plates, the former, a pressing device can be set up in a short time to produce which exactly the negative shape of the model or several on one Owns plate attached models.
Die Erfindung ist- in beiliegenden Zeichnungen durch Fig. ι im Aufrifs, durch Fig. 2 in einer Draufsicht zur Anschauung gebracht.The invention is shown in the accompanying drawings by Fig. 1 in Aufrifs, by Fig. 2 shown in a plan view.
Das abzuformende Modell α ist auf der Formplatte b befestigt, darüber ist der Formkasten c mit dem Sand- oder Füllrahmen d. Der Prefskörper besteht aus einem Rahmen e, welcher mit gleich grofsen Stäben f quadratischen Querschnitts von Holz oder anderem dazu geeigneten Material gefüllt ist. Dieselben sind mit einem Schlitz m versehen, durch welche ein Draht 0 gezogen ist. Dieser ist im Kasten e befestigt und verhindert das Herausfallen der Stäbe. Der Kasten oder Rahmen e ist mit einem Deckel h versehen, welcher mit Schrauben i befestigt wird.The model α to be molded is attached to the mold plate b , above is the molding box c with the sand or filling frame d. The prefabricated body consists of a frame e which is filled with rods f of the same size with a square cross-section made of wood or other suitable material. The same are provided with a slot m through which a wire 0 is drawn. This is attached in box e and prevents the bars from falling out. The box or frame e is provided with a cover h which is fastened with screws i.
Die Einstellung des Prefskörpers geschieht auf folgende Weise:The setting of the pref body is done in the following way:
Man bringt nach Entfernung des Deckels h den Rahmen e über das Modell a. Dadurch werden die Stäbe f, welche sich in ihrer Längsrichtung verschieben lassen, die negative Form des Modelles α annehmen. Damit sie sich nun beim darauf folgenden Pressen der Formen nicht wieder verschieben, so stampft man in den über ihnen befindlichen Raum k Sand und schraubt den Deckel h auf. Der Prefskörper wird jetzt seine Lage nicht mehr wesentlich verändern und das Formen kann in der üblichen Weise beginnen.After removing the cover h, the frame e is brought over the model a. As a result, the bars f, which can be shifted in their longitudinal direction, assume the negative form of the model α. So that they do not move again when the molds are then pressed, one stamps sand into the space k above them and unscrews the cover h . The pref body will no longer change its position significantly and the shaping can begin in the usual way.
