Embodiment Construction
[0026] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0027] Such as figure 1 and figure 2 As shown, an auxiliary positioning device 100 for cold iron in a core box 1 includes: a core box 1 for containing molding sand. An auxiliary positioning device 100 for cold iron in the core box 1 further includes: several cold iron blocks 2 for being buried in the molding sand and a positioning plate 3 for assisting the positioning of the cold iron blocks 2 . The top surface and the bottom surface of the positioning plate 3 and the top surface of the cold iron block 2 are planes.
[0028] The core box 1 is defined with a transverse axis, a longitudinal axis and a vertical axis perpendicular to each other. The positioning plate 3 is provided with several profiling grooves through which the cold iron block 2 can pass along the vertical axis so as to position the cold iron block 2 in the horizontal ax...

The invention discloses an auxiliary positioning method for a cold iron in a core box, which comprises the following steps: opening two positioning notch grooves on the side walls of opposite sides of the core box, and making a positioning gap which can be inserted into the positioning notch grooves to fill and position Notch slots to restore the two pieces of the core box; prepare the positioning plate, wherein the width of the positioning plate is the same as the width of the positioning notch groove so that the two ends of the positioning plate can be embedded in the positioning notch groove to realize the positioning of the positioning plate, according to The relative position of the positioning plate and the core box is set on the positioning plate to place a copying groove for the cold iron block; sand the molding sand in the core box to the position of the positioning notch, first scrape the molding sand, and install the positioning plate to the positioning gap In the groove, the installation position of the cold iron block can be positioned according to the position of the profiling groove; according to the installation position of the cold iron block, the sand digging operation is carried out to place the cold iron block, and the cold iron block is embedded in the profiling groove to be flush with the positioning plate. The invention is beneficial in that it can realize the positioning of the position of the dark cold iron.
Description
technical field [0001] The invention relates to an auxiliary positioning method for dark iron in a core box. Background technique [0002] The frame structure of large coal mining machinery and metallurgical machinery usually has a staggered structure of reinforcing ribs. During the casting process, this part has a large thermal joint. If a riser is placed, it will be troublesome to clean and repair the subsequent castings. Usually, the requirements for non-destructive testing of the staggered part of the reinforcement are not high. Therefore, by placing dark chilled iron to speed up the local cooling rate and realize the sequential solidification or simultaneous solidification of molten steel, it can effectively avoid large defects such as shrinkage cavities. However, in the actual modeling process, during the sand pounding process of the core box, there are certain difficulties in how to accurately locate the position of the dark cold iron inside the core box without obvio...
