Abstract
The utility model relates to a reducing gear box casing pouring structure, including the casting mould, the casting mould mainly includes the gating system and reducing gear box casing die cavity, the gating system includes sprue, cross gate and a pair of supplementary cross gate that sets up respectively between two the adjacent pouring die cavities in both sides, every pouring die cavity has a flow gate in reducing gear box casing input flange department to both sides at the inboard output terminal surface of reducing gear box casing have a pair of supplementary flow gate, the sprue is perpendicular to be set up at the centers of four pouring die cavities, and its top has a pouring basin, and cross gate and the cross gate of its bottom through both sides is linked together with the flow gate of the pouring die cavity that corresponds, prop up cross gate perpendicular to cross gate. The utility model has the advantages of: the gating system arranges rationally, and the metal fluid power is enough more abundant is full of the die cavity to obtain the higher product of quality, moreover the utility model discloses but reducing gear box casing shell structure is four products of shaping once, and production rational in infrastructure is high -efficient.
Description
Technical field
The utility model relates to a kind of cast structure, particularly a kind of reduction box casing cast structure.
Background technology
Reductor is the mechanical driving device of national economy numerous areas, industry related products classification includes all kinds of gear reduction unit, planet-gear speed reducer and worm decelerating machine, also include various dedicated transmission, as speeder, arrangements for speed regulation and all kinds of compound gearings etc. comprising flexible gearing.Product support area relates to metallurgy, coloured, the industry such as coal, building materials, boats and ships, water conservancy, electric power, engineering machinery and petrochemical industry.
Reduction box is the necessary component of reductor, main employing casting, a kind of reduction box casing as shown in Figure 2, this housing comprises enclosure body and an input 14 and two outputs 15 and 16, in process of production, because its wall thickness of its architectural characteristic is only 6mm, be easy to produce cold shut defects, although heighten pouring temperature cold shut defects can be reduced, the generation rate of thermal center defect can be increased.Therefore research and develop a kind of cast structure of castability defect of can avoiding imperative, through retrieval related documents, do not find the technical scheme identical with the utility model.
After liquid metal filling, bad in the junction melting of molten metal, and produce in foundry goods penetrate or Here it is the gap that do not penetrate cold shut phenomenon.Cold shut phenomenon comes across on the cast(ing) surface away from runner and thin-walled place more.Shape when shape is liquid flow, challengees by oneself smooth, and edge is fillet.The chemical composition of alloy is improper, it is low with pouring temperature to come out of the stove, Design of Runner System is unreasonable, ingate position is improper, the quantity of molten metal not or runout etc. cold shut phenomenon all can be caused to occur.Can say that cold shut phenomenon is one of problem more common in casting process, only do suitable improvement and just can weaken and even eliminate cold shut.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of reduction box casing cast structure that can weaken cold shut phenomenon.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of reduction box casing cast structure, its innovative point is: described running gate system comprises sprue, cross gate and is separately positioned on the auxiliary cross gate between adjacent two the cast die cavities in both sides for a pair, described each cast die cavity has an ingate at reduction box casing input flange, and the both sides of output end face have a pair auxiliary ingate inside reduction box casing; Described sprue is vertically set on the center of four cast die cavities, and its top has a pouring basin, and its bottom is connected with the ingate of corresponding cast die cavity by the cross gate of both sides and a cross gate; Described cross gate is perpendicular to cross gate.
Further, described auxiliary cross gate is H type, the running channel B be connected between a pair running channel A by the running channel A and of pair of parallel setting forms, and wherein the input of running channel B is connected with cross gate, and wherein the two ends of a pair running channel A are connected with the auxiliary ingate of corresponding cast die cavity respectively.
Further, the die cavity of described casting mold has four, and in matrix distribution on casting mold, described sprue is arranged between four die cavities.
The utility model has the advantage of:
1) the inside running channel connection and reasonable arrangement of the utility model reduction box casing cast structure, rising head position is appropriate, is convenient to implement and reduces the generation of cold shut phenomenon to a certain extent.
2) the utility model reduction box casing cast inside configuration has an auxiliary running channel of the comparatively dense in H type, guarantees that casting of molten metal fully flows into die cavity inside, reaches higher castability.
3) plastic 4 products of the utility model reduction box casing cast structure once-cast, rational in infrastructure, produces efficient.
Accompanying drawing explanation

Detailed description of the invention
As shown in Figure 1, the utility model reduction box casing structure running gate system comprises sprue 9, cross gate 4 and is separately positioned on the auxiliary cross gate 2,3 between adjacent two the cast die cavities in both sides for a pair, each cast die cavity has an ingate 6 at reduction box casing input flange, and the both sides of output end face have a pair auxiliary ingate 1 inside reduction box casing; Sprue 9 is vertically set on the center of four cast die cavities, and its top has a pouring basin 8, and its bottom is connected with the ingate 6 of corresponding cast die cavity by the cross gate 4 of both sides and a cross gate 7; Prop up cross gate 7 perpendicular to cross gate 4.
When metallic solution injects running gate system along sprue 9, metallic solution flows into cross gate 4 from sprue 9, now running gate system inside can produce the impurity of gasification, gasification impurity can overflow along rising head 5, part metallic solution directly enters in reduction box casing die cavity by a cross gate 7 from ingate 6, another part flows in auxiliary cross gate 2,3 from cross gate 4, then flow in reduction box casing die cavity by ingate 1, metallic solution is along the trickling of this path until whole reduction box casing die cavity is full of metal liquid.
More than show and describe general principle of the present utility model and principal character.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
