Servo control high-speed multi-station core making machine

Abstract

The invention relates to a servo control high-speed multi-station core making machine, which comprises a base, columns, a rotary worktable, a servo motor driving device, a mold lifting mechanism, a lower core ejecting mechanism, an auxiliary positioning mechanism, an upper beam frame, an upper mold opening mechanism, a sand blowing mechanism, a blowing mechanism and other auxiliary mechanisms, wherein three sets of core box molds can be simultaneously arranged on the rotary worktable, and a lower piece ejecting cylinder and a mold closing cylinder are arranged in the base; the columns are connected with the upper beam frame in a supporting way, and the upper mold opening mechanism, a sand storage hopper, an air pocket, a sand blowing head, a blowing head and the like are arranged on the upper beam frame. The servo control high-speed multi-station core making machine provided by the invention has the advantages of compact structure, easiness and convenience in operation of equipment, automatic control by adopting a PLC, convenience in daily maintenance, and high core making efficiency, and a core making circulation takes only about 16 seconds.

Description

technical field [0001] The invention relates to a core-making equipment, in particular to a servo-controlled high-speed multi-station core-making machine. Background technique [0002] Core-making equipment is one of the essential equipment in the production process of sand core production in foundry technology. The working principle of the core-making equipment is that the relevant parts of the core-making equipment drive the opening and closing of the core box mold, and use compressed air to instantly inject the mixed core sand into the cavity of the core box. The time of this process is generally about 3 -5 seconds, then blow the preheated triethylamine (or other catalytic gas) into the core box cavity, the core sand can be hardened in a short time (5-10 seconds) in the core box cavity, and then the sand core The sand core is ejected from the core box mold through the ejection mechanism of the core making machine. [0003] The existing core-making equipment is mainly co...
