    摘要： Foundry molding material is poured or pneumatically infed into a mold frame arrangement containing at least one pattern, a molding frame and a filling frame. Subsequently, the foundry molding material is compacted by a compacting arrangement containing, for example, any one of a compressed-air surge compacting device, a combustion-force surge compacting device, a pressure compacting device, a vibrational compacting device or a combined pressure-and-vibrational compacting device. Also during such compacting operation at least the predominant portion of the foundry molding material contained in the filling frame is displaced into the molding frame. During such compacting operation a preselected expanding gas is infed into predetermined local regions of the foundry molding material while such material is being compacted. As a result, there are formed zones of reduced packing density in the foundry molding material. During the further compacting operation, but in any case at the end of such compacting operation, the zones of reduced packing density are eliminated and the packing density of such zones is at least approximately equalized with the packing density prevailing in the remaining zones of the foundry molding material.

    摘要翻译： 将铸造成型材料倒入或气动注入包含至少一种图案，模制框架和填充框架的模具框架布置。 随后，铸造成型材料通过压缩装置压实，该压实装置包括例如压缩空气浪涌压实装置，燃烧力浪涌压实装置，压力压实装置，振动压实装置或组合的压力 - 振动压实装置。 此外，在这种压实操作期间，包含在填充框架中的至少主要部分的铸造模制材料被移动到模制框架中。 在这种压实操作期间，将预选的膨胀气体注入到铸造模制材料的预定局部区域中，同时这种材料被压实。 结果，在铸造模制材料中形成了具有降低的堆积密度的区域。 在进一步的压实操作期间，但是在任何情况下，在这种压实操作结束时，消除了堆积密度降低的区域，并且这些区域的堆积密度至少大约等于铸造剩余区域中的填充密度 成型材料。

    摘要： A moulding system for making mould parts by compacting sand or other like material between a vertical squeeze plate (12) and a vertical swingable plate (8), which form movable end walls in a squeeze chamber (6). The swingable plate is designed to swing away to allow the mould part to pass from the squeeze chamber (6) by advancing the squeeze plate (12) additionally after complete compaction. The swingable plate (8) is journalled in a foremost yoke (4), which connects with a pull yoke (2), placed behind squeeze chamber (6), by means of a rigid frame structure parallel with the longitudinal axis of the chamber.

    摘要： Apertures are formed in the top surface of the platen assembly. A resilient diaphragm extends across each aperture and is extended upwardly through the aperture by a plunger. The extended diaphragm protrudes into sand within the flask and locks the sand mold against movement parallel to the top of the platen assembly.

    摘要： The apparatus has a valve arrangement which opens rapidly due to priming or prestressing of the valve plate by the pressure in the pressure chamber. When the valve is closed, pressure, built up in the pressure chamber space closed by the valve, applies a force to the valve member in the direction of its open position. The valve member is held closed by a holder arrangement. Following the development of a predetermined pressure in the pressure chamber, the holder arrangement releases the valve member such that the pressure in the pressure chamber forces the valve member to its open position opening the pressure chamber passage and permitting the pressure medium to surge onto the surface of the molding material. This apparatus is suitable for all high-stressed gases which must be released suddenly.
