Description
Technical field
The utility model relates to belt pulley production technical field, particularly tapered sleeve 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 mould structure is simple, cost is low, fill the steady and graphited tapered sleeve belt pulley casting mould high from feeding degree of type.
The purpose of this utility model is achieved through the following technical solutions: tapered sleeve 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, the lower end of sprue is communicated with cross gate inside, cross gate is outer ring crescent shape structure, ingate is arranged at the inner side of cross gate, one end of ingate is communicated with cross gate inside, the other end of ingate is overlapped in the outer rim in pulley cast chamber, and ingate is communicated with inside, pulley cast chamber, the center in pulley cast chamber is provided with centre bore.
Described ingate has six, and wherein, three ingates are arranged at the left side of sprue, and another three ingates are arranged at the right side of sprue.
The cross section of described cross gate is rectangle, and its depth-width ratio scope is 2 ~ 3:1.
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, being overlapped in the outer rim in pulley cast chamber compared with small end of ingate.
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 hole wall of described centre bore is cone structure.
The utility model has the following advantages:
1, adopt open Circular Pouring System, Design of Gate is comparatively greatly thick, and now ingate can not only play iron liquid and enter die cavity for the first time and the effect being full of die cavity, and can also substitute the effect carrying out feeding after rising head enters die cavity for iron liquid second time.
2, adopt top pouring type cast, make that the liquid that is introduced into is static as early as possible to be solidified, graphitization expansion occurs, graphited from feeding degree to improve.Molten metal pours into die cavity from top, and molten metal is easy to be full of die cavity, can reduce the defects such as misrun.Rely on gravitational difference, easier feeding foundry goods being carried out to early stage of the liquid in running gate system.
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 die cost and the production cost casting die all compared to traditional is lower, and yield rate is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-sprue, 2-cross gate, 3-ingate, 4-cup, 5-pulley cast chamber, 6-centre bore.
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, tapered sleeve belt pulley casting mould, comprise sprue 1, cross gate 2, ingate 3 and pulley cast chamber 5, the upper end of sprue 1 is provided with cup 4, sprue 1 is perpendicular to the middle part of cross gate 2, the lower end of sprue 1 is communicated with cross gate 2 inside, cross gate 2 is outer ring crescent shape structure, ingate 3 is arranged at the inner side of cross gate 2, one end of ingate 3 is communicated with cross gate 2 inside, the other end of ingate 3 is overlapped in the outer rim in pulley cast chamber 5, and ingate 3 is communicated with inside, pulley cast chamber 5, the center in pulley cast chamber 5 is provided with centre bore 6.Each running channel cross-sectional area ratio is: ingate 3: cross gate 2: main sprue 1=17:3.5:1, adopt open Circular Pouring System, ingate 3 designs comparatively greatly thick simultaneously, now ingate 3 can not only play iron liquid and enter pulley cast chamber 5 for the first time and the effect being full of die cavity, and can also substitute the effect carrying out feeding after rising head enters die cavity for iron liquid second time.
Further, described ingate 3 has six, and wherein, three ingates 3 are arranged at the left side of sprue 1, and another three ingates 3 are arranged at the right side of sprue 1.
Further, the cross section of described cross gate 2 is rectangle, and its depth-width ratio scope is 2 ~ 3:1.
Further, described ingate 3 is the large duckbill flat structure in little rear end, front end, and the larger end of ingate 3 is connected on the madial wall of cross gate 3, being overlapped in the outer rim in pulley cast chamber 5 compared with small end of ingate 4.
Further, described cup 4 is up big and down small funnel-shaped structure, and the lower end of cup 4 and the upper end of sprue 1 are tightly connected.
Further, the hole wall of described centre bore 6 is cone structure, and direct pouring obtains conical hole, directly can carry out the taper hole that tapered sleeve is installed in fine finishining on blank, reduce molten metal consumption on the one hand, reduce the difficulty of processing taper hole on the other hand.
The course of work of the present utility model is as follows: when filling type, and molten metal flows into cross gate 2 from sprue 1, scatter from cross gate 2, enters ingate 3 from both direction, and liquid enters ingate 3 from cross gate 2, and slowly fills type.There will not be dispersing liquid to spring up to foundry goods upper strata when foundry goods lower floor is not full of completely, in whole cavity filling process, the flowing of liquid is steady, there will not be " the disorderly watering " phenomenon in conventional casting techniques, and this running gate system uniformity of temperature profile, to fill type steady.During comparatively thick large ingate 3 running gate system of casting mould employing of the present utility model, its ingate 3 can not only play and promote that iron liquid is full of the effect of die cavity, the thick large feature of ingate 3 also can be utilized to play the effect of riser feeding, at the end of cast is near, the effect of gravity can be utilized to carry out feeding to foundry goods.
