Description
Известны устройства дл верхнего прессовани , в которых оболочкова формовочна смесь загружаетс в бункер через расположенное сбоку в верхней части отверстие. При этом смесь располагаетс в бункере под углом естественного откоса, а часть диафрагмы на стороне бункера, противоположной загрузочному отверстию, остаетс не покрытой смесью, что приводит к браку оболочковой формы. Во избежание брака необходимо перед прессованием равномерно распределить смесь по площади диафрагмы. Примен емые дл выравнивани смеси вибраторы или металлические пластины вызывают преждевременное уплотнение смеси.Upper pressing devices are known in which the shell molding mixture is loaded into the hopper through a hole located in the side in the upper part. At the same time, the mixture is located in the bunker at an angle of repose, and the part of the diaphragm on the side of the bunker opposite to the loading opening remains uncovered, which leads to a marriage of the shell mold. In order to avoid marriage, it is necessary before the pressing to evenly distribute the mixture over the area of the diaphragm. Vibrators or metal plates used to level the mixture cause premature compaction of the mixture.
Известны бункеры дл нижнего прессовани оболочковых форм с применением эластичной диафрагмы. Последн под действием сжатого воздуха или жидкости поднимает засыпанную в бункер смесь и прижимает ее к разогретому модельному комплекту, располож;енному на верхней крышке- Однако в этих бзнкерах засыпаема смесь распредел етс недостаточно равномерно.Bins are known for lower pressing of shell molds using an elastic diaphragm. The latter, under the action of compressed air or liquid, raises the mixture that has been poured into the bunker and presses it to the heated model kit, located on the upper lid. However, in these cases, the mixture to be filled does not evenly distribute.
Предлагаемый бункер не имеет указанного недостатка и отличаетс тем, что в его боковой части внутри под диафрагмой помеихена площадка с приводом, воздействующа на диафрагму и поднимающа ее вверх.The proposed bunker does not have this drawback and is characterized in that in its side part inside under the diaphragm of the cross-sectional area with a drive, acting on the diaphragm and lifting it upwards.
На фиг. 1, 2 и 3 показан бункер дл нижнего прессовани оболочковых форм.FIG. 1, 2 and 3 shows a hopper for lower pressing of shell molds.
Бункер имеет загрузочное отверстие /, крыщку 2, патрубок 3 дл подвода сжатого газа под диафрагму, эластичную диафрагму 4, выравнивающее устройство 5 и корпус 6.The hopper has a loading opening /, a lid 2, a nozzle 3 for supplying compressed gas under the diaphragm, an elastic diaphragm 4, a leveling device 5 and a housing 6.
На крышку 2 бункера устанавливают модельный комплект. Через боковое отверстие / загружают оболочковую смесь 7, котора располагаетс в бункере под углом естественного откоса (см. фиг. ).On the cover 2 of the bunker set the model kit. Through the side opening / load shell mixture 7, which is located in the bunker at an angle of repose (see Fig.).
