摘要:
A mold for making dry cast concrete blocks includes a pair of vertical shoulder forming sections, one along each of the opposite sides of the mold to form vertical front shoulders of a block. Each shoulder forming section has a shoulder roughening arrangement to result in molded, roughened shoulders of the block. Methods of making such blocks and the resulting block are included.

摘要:
A mold assembly for an automated dry-cast block machine including a mold cavity formed by a plurality of frame elements, and a moveable liner plate positioned within the mold cavity and having a first major surface facing an interior of the mold cavity and a second major surface opposite the first major surface and facing away from the interior of the mold cavity, the liner plate configured to be moved toward and away from an interior of the mold cavity. At least one heater element is coupled to the second major surface of the moveable liner plate, the heater element configured to move with the moveable liner plate and to maintain the first major surface at a desired temperature.
摘要:
A mold box with an angled division plate and methods for making blocks of various shapes and sizes and columns and walls constructed with the blocks. Multiple embodiments of the mold box are disclosed for enabling different numbers of blocks and sizes of blocks to be formed in a single mold box.
摘要:
A mold assembly for manufacturing concrete blocks that is adapted for use in a concrete block machine. The mold assembly includes a plurality of liner plates, each having a major surface, the liner plates configured such that the major surfaces form a mold cavity having a desired form, and wherein at least one of the liner plates is moveable. A gear drive assembly is selectively coupled to the at least one moveable liner plate and configured to move the at least one moveable liner plate toward and away from an interior of the mold cavity. A stabilizer assembly is operatively coupled to the gear drive assembly and is configured to support the gear drive assembly as it moves the at least one moveable liner plate.

摘要:
Anti-slip floor tiles are provided which are textured with a pattern of spikes. The spikes are preferably pyramidal or conical in shape. The height, angle, and base width of the spikes are important to slip resistance coefficients. Preferred spike dimensions range from about 0.2 to about 3.0 mm in height and from about 0.8 to about 3.0 mm in base width (or diameter). Further, a process for manufacturing an anti-slip floor tile which is textured with a pattern of spikes is provided. The tile is manufactured by pressing a powder on a mold, drying the resulting tile, and then firing the pressed tile at a high temperature. The surface texture is formed by the punch of the mold press which includes spike shaped indentations being the negative of the surface of the tile.
摘要:
A plate for press-moulding dies of refractory bricks and the like, including a bearing metal slab to one face of which a lining of high wear-resistant material, normally hard metal, is applied, which is formed by a number of adjacent tiles arranged in an orderly way along parallel lines. The adjoining sides between adjacent tiles are at least in part curved.
