Abstract

The utility model discloses a one-box and two-piece braking disc casting mold core. The one-box and two-piece braking disc casting mold core comprises an upper core hub, a lower core hub and a ring-shaped core disc, wherein the upper edge of the lower core hub is provided with the ring-shaped core disc; a round groove is arranged on the inner ring of the ring-shaped core disc; the upper core hub is fastened in the ring-shaped groove. The one-box and two-piece braking disc casting mold core disclosed by the utility model has the advantages that in use, the upper core hub is fastened in the round groove arranged on the inner ring of the ring-shaped core disc to form a whole casting mold core, and is placed in a casting sand box to form two single-piece type braking disc mold cavities with an upper sand mold and a lower sand mold respectively; one side of each mold cavity is provided with a casting hole, and two single-piece type braking disc mold blanks can be cast by once casting, so that the working efficiency is improved.

Description

One case two part brake disc casting core

Technical field

The utility model relates to a kind of casting core, relates in particular to a kind of one case two part brake disc casting core.

Background technology

As depicted in figs. 1 and 2, a kind of brake disc that uses in the prior art is the one chip brake disc, and it comprises hub 1 and disc 2, casts this one chip brake disc and adopts sand casting.In the prior art, once can only form a die cavity in the casting sandbox, once can only cast out an one chip brake disc parison, inefficiency.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, makes easily, and is easy to use, and high efficiency once can cast out one case two part brake disc casting core of two one chip brake discs one the case.

The purpose of this utility model is achieved in that a kind of one case two part brake disc casting core, it is characterized in that: it comprises upper core hub, a lower core hub and a toroidal cores dish, the upper edge of lower core hub is the toroidal cores dish, above the interior ring of toroidal cores dish circular trough is set, upper core hub is fastened in the circular trough.

The utility model is compared with existing technology its advantage and is:

Upper core hub of the present utility model is an integral body, and lower core hub and toroidal cores dish are an integral body, and its profile is simple, and core is easy to manufacture.In use, upper core hub is fastened in the circular trough that the interior ring of toroidal cores dish arranges above and forms a casting core integral body, places it in the casting sandbox, and upper core hub, toroidal cores dish and top sand mold consist of the die cavity of an one chip brake disc; Lower core hub, toroidal cores dish and bottom sand mold consist of the die cavity of an other one chip brake disc; Side at two die cavities arranges plug hole, and once-cast can cast out two one chip brake disc parisons, has improved operating efficiency.
