Description

Novel casting mold capable of saving mud core

Technical Field

The utility model relates to a immersible pump sand control cover casting mould especially relates to a novel casting mould of economize loam core.

Background

Submersible pumps are a very versatile water treatment tool that operates underwater. The submersible pump is compact in structure, can be started to work only by putting the submersible pump into water during working, is simple to install and convenient to move, and is rapidly developed. But because when the aquatic sand content is big, sand can be by suction mechanical seal, and the fragile is sealed, and the motor can be intake like this, and in case the motor is intake, bearing, winding insulation damage lead to the motor to burn out. Therefore, a sand control sleeve is designed at the water inlet to prevent the sand from entering. The sand control sleeve is a step round tube with a completely through middle, is assembled on the rotor shaft, is 87mm long, is 30mm in the diameter of a through hole at the minimum middle part, is made of a gray iron casting, and is formed by a sand mold casting process. For the structure, a sand core is required to be placed when a general casting process is designed and modeled so as to form a casting blank inner cavity in the casting process, a sand core mold is required to be added so as to facilitate production of the sand-coated sand core, the production cost is high, the core making and core setting workload is large in the production process, the production efficiency is seriously influenced, and the enterprise benefit is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses thereby need the loam core down to lead to the circumstances that manufacturing cost rose and production efficiency reduced when casting to above-mentioned immersible pump sand control sleeve, thereby abandon the thinking of the loam core down when having more slot hole in the middle of traditional foundry goods, utilize the hole needs processing in the middle of the sand control sleeve, the transfer machine molding can be from the characteristics of taking the sand mould, creatively propose, use length direction's center as border, two are from taking the sand mould when molding by last case and nowel respectively, go up case and nowel from taking sand mould contact coincidence when closing the case, original loam core has been replaced like this, can form the foundry goods blank inner chamber among the pouring process, through verifying, foundry goods blank shaping is good. Therefore, the original sand core mould and the original precoated sand core can be cancelled, so that the cost of the sand core mould and the precoated sand is saved, the sand core does not need to be removed in the production process, the production efficiency is greatly improved, the problems in the background art can be effectively solved, and the enterprise benefit is improved;
