Cold and hot core box core shooter

Abstract

The invention discloses a cold and hot core box core shooter which comprises a base part, a rack, a workbench part, a core box moving trolley, an upper core box lifting part, a sand adding mechanism, a sand shooting mechanism, a blowing trolley, an upper core box and a lower core box, the sand adding mechanism comprises a sand hopper, a sand shooting cylinder and a sand shooting cover, and a first shell with a first interlayer space is arranged outside the sand shooting cylinder; a second shell is arranged outside the sand shooting cover, cooling liquid is allowed to flow through a first interlayer space of the first shell, a second interlayer space allowing the cooling liquid to flow through is formed between the sand shooting cover and the second shell, and an air blowing plate of the air blowing trolley is communicated with the air heater. According to the cold and hot core box core shooter, the shell allowing the cooling liquid to flow through is arranged outside the sand shooting cylinder and the sand shooting cover, the cooling liquid is input when a hot core is manufactured, the cooling liquid is not input when a cold core is manufactured, and therefore the core shooter can be suitable for manufacturing the cold core and the hot core at the same time, the market blank is filled, and the market competitiveness is improved. The problem that a cold core machine and a hot core machine cannot be integrated into one device is solved.

Description

Technical field [0001] The present invention relates to the field of reflecting core, and in particular, to a cold and hot core cartridge. Background technique [0002] The core machine uses the method of making the sand shell core using the core box process. Its work process is completed simultaneously, and immediately hardened in the cartridge, reducing labor intensity, easy to master, easy to master, work Keep cleaning, mechanized, automated, automated and created conditions for the process. A cycle cycle is only ten seconds to dozens of seconds, and the sand core for casting is produced. The core size manufactured by the core is accurate, and the surface is smooth. Widely used in the foundry machinery industry. [0003] The core machine is divided into a cold core cartridge and a thermochemical core cartridge. Common core machines generally only perform cold shot sand or heat shot, and the cold shot sand and thermal shot cannot be integrated on the same manner. Therefore, t...

AI Technical Summary

Problems solved by technology

[0003] Core-making machines are divided into cold-box core-shooting machines and hot-core-box core-shooting machines. Common core-making machines generally only perform cold-shot or hot-shot. Cold-shot and hot-shot can’t be integrated on the same model. Therefore, the scope of application of common core making machines is small
