Description

Single rising head sand gear ring casting mould
Technical field
The utility model is related to technical field of engineering machinery, and in particular to a kind of single rising head sand gear ring casting mould.
Background technology
Sand casting-in sand mold produces the casting method of casting.Steel, iron and most of non-ferrous alloy castings all can use Sand mould casting method is obtained.Because the Modeling Material used by sand casting is cheap and easy to get, Casting mold manufacturing is easy, to the single-piece of casting Produce, produce by batch and largely produce and adapt to, be always the basic technology in Foundry Production for a long time.
Gear ring is the drive disk assembly of key in the engineering mechanical devices such as large-scale mixing plant, mining equiment, electric machinery, During casting gear ring, rising head is used to compensate contraction, therefore the design of rising head has important shadow to the quality of gear ring blank Ring.Include being formed with using molding sand as the applicant provides a kind of gear ring sand mold (Authorization Notice No. is CN 203635862U) The molding box of gear ring die cavity, is formed with endoporus in the gear ring die cavity, rising head is provided with the endoporus, and horizontal stroke is provided between the rising head Cast gate and down gate, the edge of the gear ring die cavity are provided with steam vent.This kind of gear ring sand mold is generally symmetrically arranged with two and emits Mouthful, molten iron losing quantity is big in compensation contraction process, therefore is further improved.
Utility model content
To overcome deficiency of the prior art, the utility model provides a kind of single rising head sand gear ring casting mould, solves many The big problem of individual rising head molten iron losing quantity.
To achieve the above object, the technical solution adopted in the utility model is as follows:
Single rising head sand gear ring casting mould, single rising head sand gear ring casting mould, including gear ring die cavity is formed with using molding sand Molding box, be formed with die cavity in the gear ring die cavity, it is characterised in that:Also include rising head, down gate, runner gate and exhaust outlet, The rising head has and only one of which is connected with die cavity, and the runner gate is connected with die cavity, and the down gate is connected with rising head, described Exhaust outlet is arranged on the edge of die cavity and gear ring die cavity.
Further, also including sprue cup, the sprue cup is connected with down gate.
Further, sprue cup is taper bucket body.
Further, height of the height of rising head less than sprue cup.
Further, down gate is connected with rising head by refractory clay pipe.
From above-mentioned to description of the present utility model, compared with prior art, single rising head sand gear ring of the present utility model Casting mould, adopts using only single rising head, it is possible to decrease molten iron losing quantity, material-saving cost, improves yield rate, reduces cost.
Brief description of the drawings
Fig. 1 is single rising head sand gear ring casting mould structure schematic diagram of the present utility model.
Fig. 2 is dead head structure side view of the present utility model.
Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Shown in reference picture 1, Fig. 2, single rising head sand gear ring casting mould, including the type of gear ring die cavity is formed with using molding sand Case, is formed with die cavity 1, rising head 2, runner gate 3, down gate 4, exhaust outlet 5 and sprue cup 6 in the gear ring die cavity;
Rising head 2 connects 1 with die cavity, and the rising head 2 is pyramidal structure, has and only one of which;
Runner gate 3 connects 1 with die cavity, and the section of runner gate 2 is trapezium structure;
Down gate 4 is connected with rising head 2, and down gate 4 is connected with rising head 2 by refractory clay pipe 41;
Exhaust outlet 5 is provided with two, wherein an exhaust outlet 51 is arranged on die cavity, another exhaust outlet 52 is opened in gear ring die cavity Edge on;
Sprue cup 6 is connected with down gate 3, and the sprue cup 6 is the taper bucket body being made of aluminum dipping form, the height of sprue cup 6 Higher than and rising head 2 height.
Shown in reference picture 1, Fig. 2, above-mentioned single rising head sand gear ring casting mould, when using, by taking molten steel total amount 200kg as an example, 1530 ± 10 DEG C of pouring temperature, casting process keeps sprue cup 6 to be full of, and molten steel to rising head 1/3 subtracts stream and notes or change and poured from rising head 2 slowly Note, rising head 2 puts thermal-insulating covering agent and pumping 2 when pouring full 2/3, complete to pour.
Above-mentioned single rising head sand gear ring casting mould, adopts using only single rising head, it is possible to decrease molten iron losing quantity, material-saving Cost, improves yield rate, reduces cost.
Some specific embodiments of the present utility model are above are only, but design concept of the present utility model is not limited to This, all changes for carrying out unsubstantiality to the utility model using this design all should belong to infringement the utility model protection domain Behavior.
