A sand-shooting board with water cooling and position-limiting functions

Abstract

The invention discloses a sand shooting plate with water cooling and limiting functions. The sand shooting plate comprises a machine frame. A supporting cross beam is arranged at the upper end of the machine frame. A hydraulic system is arranged on the supporting cross beam. A sand shooting plate body is arranged below the hydraulic system. A plurality of sand nozzles which are matched for use are evenly arranged on the lower end face of the sand shooting plate body. A location pin is arranged at one side of the lower end face of the sand shooting plate body. The length of the location pin is larger than that of the sand nozzles. The supporting cross beam is further provided with a temperature compensation box body. The temperature compensation box body is provided with hoses, and the hoses are provided with corresponding hydraulic valves. Canted nozzles are arranged at the two sides of each sand nozzle, and connecting pipes are arranged between every two canted nozzles. The other ends of the hoses communicate with the connecting pipes for arrangement. According to the sand shooting plate, the limiting function can be achieved by improving the structure of the location pin, and abrasion of the sand nozzles is avoided; and meanwhile, the water cooling function of the sand nozzles can be achieved, core manufacturing operation quality is improved, the service life of equipment is prolonged, and the actual using needs are met.

Description

technical field [0001] The invention relates to a sand-shooting board with water cooling and position-limiting functions, and belongs to the technical field of sand-shooting boards. Background technique [0002] In the process of foundry production, the sand core is usually prepared by using a sand shooting device, which injects the core sand into the core box at a high speed, and then forms the core sand through compact molding; the sand shooting mechanism generally includes a sand storage cylinder, a shooting The head, and the sand-shooting exhaust mechanism, etc., among which, the sand-shooting plate on the shooting head plays a vital role in the whole process. [0003] The traditional shell core making equipment has a separate structure from the sand barrel and the sand shooting plate. The sand shooting plate is a part of the mold, which is fixed on the sand barrel by screws. When changing the mold and making cores, it needs to be replaced with the corresponding mold. T...

Problems solved by technology

[0003] The traditional shell core making equipment has a separate structure from the sand barrel and the sand shooting plate. The sand shooting plate is a part of the mold, which is fixed on the sand barrel by screws. When changing the mold core, it needs to be replaced with the corresponding mold. The supporting special shot plate has the following problems in the whole production process: (1) The positioning pins in the prior art are relatively short, resulting in greater wear and tear on the sand nozzle, which seriously affects the service life of the sand nozzle; (2) Sand nozzle operation produces high temperature, which affects the quality of core making operation
