The invention relates to a preparation method of high temperature resistant dope for lost foam. The invention comprises the following components by weight percent: 2 to 3 fire clay, 25-50 black charcoal ash, 5 to 6 hard charcoal ash and 10 polyvinyl acetate emulsion, which are mixed to obtain a condensate. Water is added to the condensate according to the weight proportion of 1 to 5-20. The water and the condensate are mixed evenly and the dope is prepared. The invention adopts water as solvent, which is non-toxic, tasteless and has no pollution. The black charcoal ash, the hard charcoal ash, the polyvinyl acetate emulsion anti-burnt-on sand and the fire clay can resist the high temperature of more than 1500 degrees centigrade. The dope manufactured through the method has good suspension property and a compact high-strength coating can be formed on the surface of a foam plastic mould. The disposable falling off percentage of the dope layer of casting finished products is improved further ...

The invention discloses a sliding block bottom plate of a numerical control press, and relates to an improvement on the structure of an upper die installation pedestal of a stamping die in the application process. Coaxiality of an upper die punch head and a lower die upper hole groove is ensured. The press is provided with a lower die sleeve, and the sliding block bottom plate is provided with a positioning pin hole coaxial with the lower die sleeve. After the position of the lower die upper hole groove is determined, the sliding block bottom plate (directly the bottom of a sliding block or the bottom of a sliding block and a substrate) of the equipment is provided with the positioning pin hole for positioning connection with a subsequently installed punch head. Therefore, axis superposition of the punch head and the lower die upper hole groove can be ensured. Furthermore, the processing precision is improved, and the strength of installing the die by operators is reduced. The sliding block ...
