Abstract

The invention provides a heat core box mold of a flange yoke. The heat core box mold comprises a convex mold and a concave mold; a molding cavity for controlling the shapes of products is formed between the convex mold and the concave mold; the molding cavity is divided into a convex mold cavity and a concave mold cavity; an independent small molding cavity is formed between the convex mold cavity and the concave mold cavity; and two core molding cavities are formed in the upper part of the molding cavity between the convex mold and the concave mold. The heat core box mold has the following beneficial effects: the efficient casting can be realized; the casting defects can be reduced; the casting yield is increased; the casting speed can be accelerated through adjusting the position of a pouring gate to increase the yield; and the sand consumption in core production can be reduced due to independent production of cores.

Description

technical field [0001] The invention relates to the field of tooling for core shooters, in particular to a hot core box mold for a flange fork. 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 core box mold through the sand injection nozzle. [0003] In the prior art, the flange yoke is mainly used for bearings. Due to the larger structure of the flange yoke, the flange yoke is cast in one piece. However, when designing the...
