Description
Посто нные формы, штампы, прессформы обычно изготовл ютс механическим путем, что требует затраты механического оборудовани и обходитс дорого. Негативный способ отливки, отливка в стержн х и др. не дают точных размеров, чистой поверхности и требуют дополнительной механической обработки.Permanent molds, dies, molds are usually manufactured mechanically, which requires the expense of mechanical equipment and is expensive. Negative casting method, casting in rods, etc. do not give accurate dimensions, clean surface and require additional mechanical processing.
Попытки получить посто нные формы методом лить под давлением не увенчались успехом вследствие приварки жидкого металла к модели.Attempts to obtain permanent molds using the injection molding method were unsuccessful due to the welding of the liquid metal to the model.
Предлагаемый способ центробежной отливки форм устран ет возможность приварки жидкого металла к модели, так как изложнице с моделью формы сообщают вращение в таком направлении, чтобы жидкий металл отбрасывало в сторону, противоположную стороне креплени модели.The proposed method of centrifugal casting of molds eliminates the possibility of welding the molten metal to the model, since the mold with the mold model is shown to rotate in such a direction that the liquid metal throws in the direction opposite to the model's attachment side.
На фиг. 1 изображена в плане изложница дл осуществлени предлагаемого способа; на фиг. 2 - схема правильного направлени вращени изложницы; на фиг. 3 - схема неправильного направлени вращени изложницы; на фиг. 4 и 5 - вид сбоку и в плане изложниц дл массовой отливки формы; на фиг. 6 - вид разных форм литейных чащ.FIG. Figure 1 shows a mold for carrying out the proposed method; in fig. 2 is a diagram of the correct direction of rotation of the mold; in fig. 3 is a diagram of the wrong direction of rotation of the mold; in fig. 4 and 5 are side and in view of molds for mass mold casting; in fig. 6 is a view of various forms of foundry thickets.
Изложница 7 состоит из двух частей 1, скрепленных скобами 2, и вращаетс вокруг оси, перпендикул рной к плоскости чертежа и проход щей через точку 0.The mold 7 consists of two parts 1, fastened with brackets 2, and rotates around an axis perpendicular to the plane of the drawing and passing through point 0.
В част х 1 изложницы 7 устанавливаютс подмодельные плиты, на которых смонтированы и укреплены модели 3, предназначенные дл отливки.In parts 1 of the mold 7, base plates are mounted on which models 3 are mounted and fixed for casting.
В тех случа х, когда отлита форма будет удал тьс из изложницы 7 посредством толкателей, к модели 3 прикрепл етс стержень 4. Стержень 4 имеет форму и размеры будущего толкател . Этот стержень предназначен дл получени в отлитой форме готовых отверстий дл толкателей.In those cases when the mold is removed from the mold 7 by means of pushers, a rod 4 is attached to the model 3. The rod 4 has the shape and dimensions of the future pusher. This rod is designed to produce ready-made pusher holes in molded form.
При освобождении модели из отлитой формы этот стержень вл етс точкой приложени силы, что сохран ет модель от повреждени .When the model is released from the molded form, this rod is the point of application of force, which saves the model from damage.
Отливка посто нных форм происходит следующим образом. Изложница 7 крепитс к столу центробежной мащины. Определенна дозаCasting of permanent forms is as follows. The mold 7 is attached to the table centrifugal maschina. Determined dose
