Fully automatic sand molding machine

Abstract

The invention discloses a full-automatic sand covering molding machine, and belongs to casting equipment. The full-automatic sand covering molding machine comprises a rack, a sand-covering and sand-blasting device is arranged at the top of the rack, a mold-closing and mold-lifting device is arranged at the bottom, located at the bottom of the sand-covering and sand-blasting device, of the rack, aconveying device which is horizontally arranged is arranged in the middle part, located between the sand-covering and sand-blasting device and the mold-closing and mold-lifting device, of the rack, afirst station and a second station which are used for placing iron molds are arranged on the conveying device, meanwhile positioning mechanisms used for fixing the iron molds are arranged at the positions, corresponding to the first station and the second station, of the conveying device, and a first discharging device and a second discharging device which are arranged perpendicular to the conveying device are arranged at the two ends, located on the conveying device, of the rack. The full-automatic sand covering molding machine has the effect of improving the processing efficiency.

Description

technical field [0001] The invention relates to casting equipment, in particular to an automatic sand-covered molding machine. Background technique [0002] Sand-covered iron casting is one of the special castings. With the development of my country's automobile industry, it is more and more widely used. The core equipment of iron mold sand-covered casting is sand-covered molding machine. At present, there are mainly double-station sand-covered molding machines, which are mainly used for sand-coated molding of iron molds with a plane size within 1500mm*700mm. At present, with the continuous promotion of the application of sand-covered iron molds, more and more products are used. [0003] For the prior art, please refer to the Chinese invention patent with the authorized announcement number CN102861880B, which discloses a sand-covered molding device and method for a large iron mold. The roller table, the upper beam is equipped with a sand-coated blasting device, the lower b...

Problems solved by technology

[0004] However, there are following deficiencies in the above-mentioned invention patents: after the model of the lifting mold clamping and ejecting device is formed, the iron mold box delivery device will transport the iron mold through the model conveying roller table to the frame, remove the iron mold and install a new one. After ironing the mold, the iron mold box delivery device will transfer the iron mold to the bottom of the sand-coated sand blasting device. When the iron mold is unloaded and a new iron mold is installed, the sand-coated sand blasting device is in a state of stop working , resulting in low processing efficiency
