Description
Technical field
The utility model relates to casting mould design field, specifically a kind of brake drum casting mold.
Background technique
Since brake drum demand is big, 2 production methods of currently used 1 mould are difficult to ensure delivery demand, and produce effect
Rate is low, and product yield is 71.82%(product yield=every case casting weight/(casting weight of every case+running gate system weight
Amount)), every furnace be poured 36 casees 72.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model, which provides one kind, can increase every case product quantity, mention
The brake drum casting mold of high technology yield rate and production efficiency.
The technical solution adopted in the utility model is: a kind of brake drum casting mold, including the mold being arranged in sandbox
Ontology and running gate system；The running gate system includes sprue, cross gate, ingate and riser；
The die ontology includes three brake drum shaping moulds in isosceles triangle arrangement, two brakings positioned at bottom
It is equipped with vertical sprue between drum shaping mould, the brake drum shaping mould positioned at top is formed with two brake drums for being located at bottom
Riser is respectively equipped between mould；The riser is equipped with gas vent；The sprue is sequentially connected with cross gate, ingate, interior
Running channel and the tangent setting of brake drum shaping mould, liquid metal enter brake drum shaping mould through sprue, cross gate, ingate.
Further, the cross gate is made of the second segment of the first segment and zigzag shape structure that are laterally arranged.
Further, filter screen is equipped with below the sprue.
Further, the riser is equipped with fracture stress slot.
The beneficial effects of the utility model are: 1 mould, 2 production methods are changed to 1 mould 3, and change corresponding casting system
System and production technology greatly improve production efficiency, reduce production cost；After being changed to 1 mould, 3 production technologies, product yield
Reach 79.7%, 108, every furnace 36 casees.
Detailed description of the invention
Fig. 1 is the structure top view of the utility model.
In figure: 1, die ontology, 2, brake drum shaping mould, 3, riser, 4, sprue, 5, cross gate, 501, first segment,
502, second segment, 6, ingate.
Specific embodiment
It is further to the utility model with reference to the accompanying drawing in order to be more clearly understood that the technical solution of the utility model
Explanation.
A kind of brake drum casting mold as shown in Figure 1, including the die ontology 1 being arranged in sandbox and running gate system；
The running gate system includes sprue 4, cross gate 5, ingate 6 and riser 3；
The die ontology 1 includes three brake drum shaping moulds 2 in isosceles triangle arrangement, two systems positioned at bottom
It is equipped with vertical sprue 4 between dynamic drum shaping mould 2, the brake drum shaping mould 2 positioned at top and two brakings positioned at bottom
Riser 3 is respectively equipped between drum shaping mould 2；The riser 3 is equipped with gas vent and fracture stress slot；The sprue 4 and cross
Running channel 5, ingate 6 are sequentially connected, and several ingates 6 are with the tangent setting of brake drum shaping mould 2, and liquid metal is through sprue
4, cross gate 5, ingate 6 enter brake drum shaping mould 2；The cross gate 5 is by the first segment 501 and zigzag shape knot that are laterally arranged
The second segment 502 of structure forms, and shunts the liquid metal flowed out from sprue 4；Filter screen is equipped with below the sprue 4, it is right
The liquid metal for pouring into sprue 4 is filtered.
Each ingate 6 is with the tangent setting of brake drum shaping mould 2, and liquid metal is through the entrance brake drum molding of ingate 6
During mould 2, tangential force can be generated, pushes liquid metal rotation, until completing entirely to pour into process, is finally cooled into casting
Part, avoids the generation of sand washing phenomenon, and ensure that the liquid metal mixing uniformity of each ingate 6, improves technique and goes out
The quality of product rate and yield rate and casting.
Working principle: the liquid metal for pouring into sprue 4 introduces brake drum shaping mould 2 through cross gate 5, ingate 6, with
The continuous injection of liquid metal, liquid level constantly rises in brake drum shaping mould 2, generates in casting process because casting mold is heated
Gas is emitted into atmosphere by the gas vent on riser 3；Due to that can shrink in liquid metal cooling procedure, riser is designed
3 for compensating liquid metal, and liquid metal used in casting enters in riser 3 through Feeding channel, and riser 3 is answered equipped with fracture
Power slot reduces the contact area of riser and casting, and when remove feeders 3 is directly tapped with hammer, emits the fracture of opening's edge fracture stress slot,
The defects of casting shape is complete, without misrun.
1 mould, 2 production methods are changed to 1 mould 3 by the utility model, and change corresponding running gate system and production technology,
Production efficiency is greatlyd improve, production cost is reduced；After being changed to 1 mould, 3 production technologies, product yield has reached 79.7%, often
108, furnace 36 casees.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
