Description
Technical field
The utility model relates to belt pulley production technical field, particularly dual grooved V-shaped belt pulley casting mould.
Background technology
The material that existing belt pulley foundry goods uses mostly is HT200, i.e. casting pig material.The casting character of casting pig, machinability, wearability are all better than other all kinds of cast iron.Solidification mode due to casting pig is consecutive solidification, and its graphitization expansion Chang Buneng offsets the volume contraction of process of setting completely, often needs the external world to carry out feeding in process of setting.
Belt pulley belongs to hub class part, and only the output of China's belt pulley in 2013 is just more than 5.5 hundred million.As the main kit of transmission system, the development of belt pulley is the most important thing in the sector and whole industrial production.In traditional belt pulley Foundry Production, ingate is only adopt general rectangle or cylinder form design, such design not only can not form thermal pressure and thermograde, also easily causes dispel the heat faster, iron liquid of ingate more first to solidify, thus the flowing blocking follow-up iron liquid with supplement.Meanwhile, all adopt the running gate system of band rising head in conventional belt wheel Design of Runner System, this type of design not only increases the consumption of iron liquid, loaded down with trivial details subsequent machining operations, improves production cost; And easily introduce introduced contaminants and gas from rising head, form field trash and gas hole defect at cast-internal, have a strong impact on internal soundness and the product yield of foundry goods.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of compact conformation is simple, convenient operation, fills steady, the graphited and dual grooved V-shaped belt pulley casting mould that production cost low high from feeding degree of type.
The purpose of this utility model is achieved through the following technical solutions: dual grooved V-shaped belt pulley casting mould, comprise sprue, cross gate, ingate and pulley cast chamber, the upper end of sprue is provided with cup, sprue is perpendicular to the middle part of cross gate, cross gate is outer ring crescent shape structure, and ingate is arranged at the inner side of cross gate; Pulley cast chamber comprises wheel rim casting chamber, spoke casting chamber and wheel hub casting chamber, wheel rim casting chamber is annular cavity type body structure, four spokes casting chamber is uniformly distributed along the radial direction in wheel rim casting chamber, wheel hub casting chamber is arranged at the center in wheel rim casting chamber, wheel rim casting chamber, spoke casting chamber are communicated with successively with wheel hub casting chamber, and described ingate and wheel rim are cast chamber and be communicated with.
The cross section of described cross gate is rectangle, and its depth-width ratio scope is 1.5 ~ 2:1.
Described ingate is the large duckbill flat structure in little rear end, front end, and the larger end of ingate is connected on the madial wall of cross gate, and the comparatively small end of ingate is overlapped on wheel rim casting chamber.
Described cup is up big and down small funnel-shaped structure, and the lower end of cup and the upper end of sprue are tightly connected.
The utility model has the following advantages:
1, molten metal pours into die cavity from top, and die cavity is easy to be full of, and can reduce the defects such as cold shut, employing top pouring type is poured into a mould, and make solidifying of liquid occur consecutive solidification, the liquid be introduced into is static as early as possible to be solidified, graphitization expansion is there is in process of setting, graphited from feeding degree to improve.
2, by unchoked running system, ingate height is fixed, and the sectional area of ingate and the sectional area of cross gate are more or less the same, when therefore filling type, ingate pressure is less, steady when filling type, the iron liquid in Circular Pouring System can also as outside feeding metal, and the initial stage of feeding foundry goods shrinks.
3, the simple and compact structure of this running gate system, is convenient to the operations such as moulding, and molten metal consumption is few, and its casting technique yield rate is higher.
4, mould of the present utility model also avoid the required chill used in general casting technique, not only effectively can reduce numerous operations of later stage frock, remarkable improving production efficiency and economic benefit.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional structure schematic diagram in pulley cast chamber;
In figure: 1-sprue, 2-cup, 3-cross gate, 4-ingate, 5-pulley cast chamber, 6-wheel rim casting chamber, 7-spoke casting chamber, 8-wheel hub casting chamber.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, dual grooved V-shaped belt pulley casting mould, comprise sprue 1, cross gate 3, ingate 4 and pulley cast chamber 5, the upper end of sprue 1 is provided with cup 2, sprue 1 is perpendicular to the middle part of cross gate 3, cross gate 3 is outer ring crescent shape structure, and ingate 4 is arranged at the inner side of cross gate 3; As shown in Figure 2, pulley cast chamber 5 comprises wheel rim casting chamber 6, spoke casting chamber 7 and wheel hub casting chamber 8, wheel rim casting chamber 6 is annular cavity type body structure, four spokes casting chamber 7 is uniformly distributed along the radial direction in wheel rim casting chamber 6, wheel hub casting chamber 8 is arranged at the center in wheel rim casting chamber 6, wheel rim casting chamber 6, spoke casting chamber 7 are communicated with successively with wheel hub casting chamber 8, and described ingate 4 and wheel rim are cast chamber 6 and be communicated with.
Further, the cross section of described cross gate 3 is rectangle, and its depth-width ratio scope is 1.5 ~ 2:1, each running channel cross-sectional area ratio is: ingate 4: cross gate 3: sprue 1=2.6:2.1:1, adopt unchoked running system, ingate 4 is highly fixing, and the sectional area of ingate 4 and the sectional area of cross gate 3 are more or less the same, when therefore filling type, ingate pressure is less, steady when filling type.Iron liquid in Circular Pouring System can also as outside feeding metal, and the initial stage of feeding foundry goods shrinks.
Further, as shown in Figure 1 or 2, described ingate 4 is the large duckbill flat structure in little rear end, front end, and the larger end of ingate 4 is connected on the madial wall of cross gate 3, and the comparatively small end of ingate 4 is overlapped on wheel rim casting chamber 6.
Further, described cup 2 is up big and down small funnel-shaped structure, and the lower end of cup 2 and the upper end of sprue 1 are tightly connected.
The course of work of the present utility model is as follows: molten metal flows into cross gate 3 from sprue 1, scatter from cross gate 3, ingate 4 is entered from both direction, slowly type is filled to pulley cast chamber 5, in whole cavity filling process, Temperature Distribution is uniform, not having dispersing liquid when foundry goods lower floor is not full of completely springs up to foundry goods upper strata, in whole cavity filling process, the flowing of liquid is steady, do not occur " the disorderly water " phenomenon in general casting technique, and this running gate system uniformity of temperature profile, to fill type steady.Along with the prolongation of filling time, the cavity filling process of foundry goods is transitioned into foundry goods upper strata gradually from foundry goods lower floor, terminates until fill type.
