Core box mold of ZM bearing seat

Abstract

The invention provides a core box mold of a ZM bearing seat. The core box mold of the ZM bearing seat comprises a sand seat mold and a sand cover mold. A sand shell can be manufactured through the sand seat mold, wherein the shape of the sand shell is the same with the shape of the exterior of a base of the bearing seat. A sand shell can be manufactured through the sand cover mold, wherein the shape of the sand shell is the same with the shape of an upper cover of the bearing seat. The sand seat mold comprises a sand seat upper mold and a sand seat lower mold. The sand cover mold comprises a sand cover upper mold and a sand cover lower mold. Five sand shooting openings are formed in the lower sides of the sand seat lower mold and the sand cover lower mold. Air exhausting troughs are formed in the other three sides of the sand seat lower mold and the other three sides of the sand cover lower mold. The core box mold of the ZM bearing seat has the beneficial effects that according to the core box mold of the ZM bearing seat, mechanical machining of the manufactured bearing seat can be reduced, the cost of materials and manual work is saved, and automated production is easy to achieve.

Description

technical field [0001] The invention relates to the field of tooling for core shooting machines, in particular to a core box mold for a ZM bearing seat. Background technique [0002] At present, my country's foundry industry generally uses hot core boxes to manufacture sand cores. The production process is roughly as follows: the sand material mixed with foundry sand, thermosetting resin and catalyst is injected into the core box with a heating device through a core shooter, and heated to 250 to 320 degrees Celsius to make the sand material close to the surface of the core box When heated, the binder in the sand can be polycondensed and hardened in a short period of time to form a core. The foundry sand is generally injected into the cavity of the hot box mold through the sand injection nozzle. [0003] In the existing machinery industry, bearing seats are widely used. During the design and production process of bearing seat core box molds, due to the large volume of som...

AI Technical Summary

Problems solved by technology

[0003] In the existing machinery industry, bearing seats are widely used. During the design and production process of bearing seat core box molds, due to the large volume of some bearing seats, the depth of the cavity is relatively large when designing the core box. Therefore, it is necessary to increase the height of the gate accordingly, and the position of the gate and the structure of the sand injection port have a great influence on the later casting. Unreasonable settings can easily lead to an increase in the rate of casting rejects; in the application of bearing seats, there will be problems with The core used with the bearing seat, because the core structure is relatively complex, and the core is easy to break or break after core making
