Abstract

The invention provides a vertical sand shooting device, relating to the technical field of casting. The vertical sand shooting device comprises a rack, a sand shooting box for containing clay sand, alifting device for driving the sand shooting box to lift, a dome valve connected with the sand shooting box and arranged at a sand inlet, a compacting plate connected with the sand shooting box and covering a sand shooting opening, an air inlet pipe and a molding chamber; one end of the air inlet pipe communicates with compressed air, while the other end of the air inlet pipe communicates with theinside of the sand shooting box; the molding chamber is disposed under the sand shooting opening, and an opening is formed in the upper part of the molding chamber; the cross section of the compacting plate is smaller than or equal to the opening in the upper part of the molding chamber, so that the compacting plate can extend into the sand shooting box. The vertical sand shooting device in sucharrangement can directly shoot sand vertically downwards without the speed loss during angle conversion, and the shooting speed of the clay sand is higher; the vertical sand shooting device is not provided with a sand storeroom, and sliding seal between the sand shooting box and the sand storeroom is avoided, so that the problem of air release and sand leakage due to poor sealing is prevented; thevertical sand shooting device has a simpler structure and a lower failure rate.

Description

technical field [0001] The invention relates to the technical field of casting, and more specifically relates to a vertical sand shooting device. Background technique [0002] In the modern foundry production process, in order to improve the casting efficiency and meet the requirements of modern production, most of the sand molds used in the casting process are made by horizontal boxless molding machines, which are widely used in the foundry machinery industry. The horizontal boxless molding machine in the prior art mainly includes a sand warehouse for storing clay sand and a sand shooting mechanism connected with the sand warehouse. The sand warehouse is usually arranged on one side of the sand shooting mechanism, so the clay sand can Inside, the flow direction is changed to a vertical direction through a 90-degree turn angle to enter the sand shooting mechanism. The clay sand enters the vertical sand shooting mechanism from the sand storehouse on one side, and the sand sho...
