Description

High efficiency flying wheel shaping mould

Technical field

The utility model belongs to casting field, specifically, particularly relates to a kind of high efficiency flying wheel shaping mould.

Background technology

Flywheel is widely used in automotive field, and flywheel generally adopts casting, especially with precoated sand is to contain.Existing cast adopts single moulding by casting more, and after cast, cool time is long, and production efficiency is low, cannot realize batch production.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of high efficiency flying wheel shaping mould, and the multiple flywheel blank of energy one-time cast-forming, shortens cool time, enhance productivity.

For this reason, the technical scheme that the utility model adopts is as follows: a kind of high efficiency flying wheel shaping mould, comprise arenaceous shell, lower arenaceous shell and cast gate, it is characterized in that: described upper arenaceous shell and lower arenaceous shell snap together formation two separate and with the die cavity of flywheel outline, two die cavities are symmetrical, upper, lower arenaceous shell is respectively arranged with cast rising head, described cast rising head center ofthe between two die cavities and outside die cavity is arranged, in the inner chamber of upper arenaceous shell or lower arenaceous shell, be provided with short slot will pour into a mould rising head and be communicated with two die cavities, the outer wall of upper arenaceous shell is provided with locating dowel, the outer wall of lower arenaceous shell is provided with lower locating dowel, in upper locating dowel and lower locating dowel, one of them is solid, another is hollow, hollow internal diameter mates with solid external diameter, to ensure that hollow locating dowel can be inserted in solid locating dowel,

Described cast gate forms " ⊥ " shape three-way pipe by a charging aperture, two discharging openings, and charging aperture is perpendicular to discharging opening;

Described upper arenaceous shell and lower arenaceous shell snap together formation casting moulds, some casting moulds to be together in series all through casting moulds of formation one row die cavity successively by cast rising head, and by upper locating dowel and lower locating dowel location between adjacent casting moulds, each discharging opening of cast gate connects a row casting moulds, between the discharging opening of cast gate and the cast rising head of first casting moulds, again by bonding leakproof after splicing between the cast rising head of each casting moulds adjacent, a cast rising head idle on the casting moulds of end is sealed by plug.

Be preferably, often row casting moulds has 6, two row casting moulds totally 12, can one-time cast-forming 24 flywheel blanks.

The beneficial effects of the utility model: the structure optimizing arenaceous shell, lower arenaceous shell and cast gate, set up location structure, ensure that each casting moulds of series connection can not misplace; Two die cavities are set in same casting moulds, cast rising head is arranged between two die cavities, and short slot is set in a cast rising head wherein and will pours into a mould rising head and be communicated with two die cavities, bond together after the cast rising head of adjacent casting moulds splices, realize the object that once-cast two arranges multiple casting moulds; Rational in infrastructure, design ingenious, suppose often to show 6 casting moulds, then once pourable shaping 24 flywheel blanks.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Shown in composition graphs 1-Fig. 2, a kind of high efficiency flying wheel shaping mould, forms primarily of upper arenaceous shell 1, lower arenaceous shell 2 and cast gate 3, and three all adopts precoated sand to make on core shooter.Adopt precoated sand on core shooter, make arenaceous shell and cast gate, be conventional art, do not repeat them here, core is improved and is the version optimizing upper arenaceous shell 1, lower arenaceous shell 2 and cast gate 3, realizes the object of the multiple flywheel of one-time cast-forming.

Shown in composition graphs 1-Fig. 5, upper arenaceous shell 1 and lower arenaceous shell 2 snap together formation two separate and with the die cavity of flywheel outline, two die cavities are symmetrical.Upper and lower arenaceous shell 1,2 is respectively arranged with cast rising head 4, and the cast rising head 4 on upper arenaceous shell 1 flows into for molten steel, and the cast rising head 4 on lower arenaceous shell 2 flows out for molten steel.Cast rising head 4 is between two die cavities and in the outer center ofthe setting of die cavity, the cast rising head 4 of upper and lower arenaceous shell 1,2 is coaxially arranged.

In the inner chamber of upper arenaceous shell 1, be provided with short slot 5 will pour into a mould rising head 4 and be communicated with two die cavities, short slot 5, in "eight" shape, ensures that the molten steel of cast can flow in two die cavities through cast rising head 4 simultaneously.Certainly, short slot 5 also can be arranged in the inner chamber of lower arenaceous shell 2.The outer wall of upper arenaceous shell 1 is provided with locating dowel 1a, the outer wall of lower arenaceous shell 2 is provided with lower locating dowel 1b.In upper locating dowel 1a and lower locating dowel 1b, one of them is solid, and another is that hollow, hollow internal diameter mates with solid external diameter, to ensure that hollow locating dowel can be inserted in solid locating dowel.

Shown in composition graphs 1, Fig. 6, cast gate 3 forms " ⊥ " shape three-way pipe by a charging aperture, two discharging openings, and charging aperture is perpendicular to discharging opening.

Upper arenaceous shell 1 and lower arenaceous shell 2 snap together formation casting moulds, some casting moulds to be together in series all through casting moulds of formation one row die cavity successively by cast rising head 4, and located by upper locating dowel 1a and lower locating dowel 1b between adjacent casting moulds, each discharging opening of cast gate 3 connects a row casting moulds.Between the discharging opening of cast gate 3 and the cast rising head 4 of first casting moulds, again by bonding leakproof after splicing between the cast rising head 4 of each casting moulds adjacent, a cast rising head 4 idle on the casting moulds of end is sealed by plug 6, leaks to prevent molten steel.

Preferably, often row casting moulds has 6, two row casting moulds totally 12, energy one-time cast-forming 24 flywheel blanks; But be specifically not limited thereto, can select to determine according to actual conditions.

During concrete enforcement, high efficiency flying wheel shaping mould is put into the container of open top and the charging aperture ensureing cast gate 3 upward, facilitate pour steel.Pour in container by shot or shot again, whole container is placed on shake table, utilizes that low frequency is micro-to shake shot or shot jolt ramming, thus utilize shot or shot to be compressed by casting moulds, prevent casting moulds to be out of shape, ensure product quality, and ensure that the charging aperture of cast gate 3 is outside exposed.Finally poured into from the charging aperture of cast gate 3 by the molten iron after heating and pour into a mould, molten iron is flowed in each die cavity of two row casting moulds respectively by the discharging opening of cast gate 3.

The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
