A core shooter

Abstract

The invention discloses a core shooter. The core shooter comprises a rack, at least four sand supplying assemblies which are arranged on a top plate, and at least four mold assemblies, wherein the rack is provided with the top plate, a bottom plate and a roller way for iron type driving; each sand supplying assembly comprises a movable sand shooting head, a pressing cylinder for providing a pressing force for the sand shooting head and a sand hopper for supplying sand grains; each mold assembly comprises a ground track arranged on the bottom plate, a sliding device which is slidably arranged on the ground track and a lifting mechanism of a mold and the sliding device, wherein the mold is arranged on the sliding device and is staggered from the roller way in a direction perpendicular to the bottom plate, and the lifting mechanism can move along the direction perpendicular to the bottom plate by driving the mold; the mold assemblies and the sand supplying assemblies are arranged in a manner of one-to-one correspondence. According to the core shooter, each mold assembly can slide on the bottom plate, and the mold and the roller way are staggered in the direction perpendicular to the bottom plate, so that the problem that the mold positioned right below the roller way is inconvenient to disassemble, assemble and sweep when the mold and the roller way are noncollinear in a vertical direction is solved. Thus, the sweeping effect is improved, and a product is prevented from being polluted by impurities. As a result, the quality of the product is improved.

Description

technical field [0001] The invention relates to the technical field of industrial machinery, and more specifically relates to a core shooter. Background technique [0002] The core shooter uses coated sand to make the core. Because of its precise core size and smooth surface, it is widely used in the foundry industry. The working principle of the core shooting machine is to inject the sand with solid thermosetting resin as the binder into the heated iron mold or core box, and the sand will harden quickly after preheating in the iron mold or core box, so as to form a smooth surface, precise size and high precision. The model cavity is used to cast a casting with a smooth surface and high-precision dimensions. [0003] At present, the mold of the existing core shooting machine is fixed on the base of the core shooting machine, and the iron mold can move on the roller table of the core shooting machine to realize the positioning and separation of the iron mold and the mold.

Problems solved by technology

However, since there is only one mold assembly and sand supply assembly, it is impossible to mold multiple iron molds at the same time; and because the mold is fixed directly below the roller table, there is no room for operation, and it is not easy to clean the slag on the mold, and it is also not easy to install. Dismantling the mold will easily cause unclean cleaning and affect product quality, and the production efficiency is low and the labor intensity is high
