摘要： The present invention relates to the field of foundry and namely to a process and a device (embodiments) for preparing mold-sand. To provide a possibility to check the moisture content during the process of the mold-sand preparation and to adjust the moisture content in the considered mix batch, in the process for preparing mold-sand comprising the steps of pouring a proportioned amount of mold-sand components into a mixer, adding the calculated amount of water, mixing the components, taking a sample and measuring the mold-sand moisture content, according to the invention, after taking a representative sample from the mixer, this sample is used to make a specimen by its compaction, and the moisture content is measured with the consequent adjustment of the moisture content in the considered mix batch, and in the device for preparing mold-sand comprising a mixer under the form of a fixed pan containing mixing elements under the form of shares and of vortex heads, and an assembly for controlling the mold-sand mix moisture fixed on a wall of said pan above the level of the shares, according to the invention, the assembly for controlling the mold-sand mix moisture comprises a case for forming a specimen and fixed obliquely on the wall of the fixed pan, at one end of which a plunger with a built-in moisture probe and an air cylinder are mounted, its other open end located inside the mixer being provided with a periodically-operated butterfly valve serving to fill the case with mold-sand, with an additional air cylinder.

摘要： The invention relates the field of foundry and namely to the technology and the equipment for manufacturing sand and loam casting molds with the use of a method of pulsed-air compacting of mold-sand in combination with compacting by compression.
To improve the precision, to reduce the number of defects in the castings and to increase the metal content in the molds, the pulsed-air compacting of the mold-sand is supplemented by an operation of re-compacting the mold-sand by pressing which is performed with the pattern plate containing the patterns by means of the plate moving inside the cavity of the filling frame in the direction of the latticed pressing element which is subjected to a counter-pressure force corresponding in its value to the prescribed level of the half mold compaction. The process is realized with a device in which the pattern plate containing the patterns is mounted with the possibility of a reciprocal motion inside the cavity of the filling frame, and the pressing cylinder is mounted with the possibility to apply a force against the movable pattern plate. The filling with the mold-sand in layers is performed by a device providing the possibility of a reciprocal motion of the molding table relative to the feeder or, according to another embodiment, with the help of an oscillating mold-sand duct subjected to reciprocal and angular motions above the casting box with a determined rate.

摘要翻译：本发明涉及铸造领域，即涉及使用模砂的脉冲空气压实与压缩压实相结合的技术和制造砂土壤模具的设备。为了提高精度，为了减少铸件中的缺陷数量和增加模具中的金属含量，模具砂的脉冲空气压实通过压制模具砂的操作来补充通过在填充框架的空腔内沿着格栅按压元件的方向移动的板，其中包含图案的图案板被执行，该板被承受相当于其值的反压力至所述一半的规定水平模具压实。该过程通过一种装置来实现，其中装有图案的图案板可以在填充框架的空腔内相互运动的可能性被安装，并且按压筒被安装成可能施加力到可移动图案板。模具砂层的填充通过提供模制台相对于进料器的往复运动的可能性的装置来实现，或者根据另一个实施例，借助于经受倒数和以确定的速率在铸造箱上方的角运动。 III。 2页
