Description
Technical field
The present invention relates to a kind of brake disc gap pouring devices, belong to auto parts casting technology field.
Background technique
Brake disc is exactly in simple terms a round plate, it is also rotation when car is advanced.Brake caliper is clamped
Brake disc and generate brake force, be exactly that it clamps brake disc and plays the role of slowing down or stopping when touching on the brake.Brake disc system
Dynamic effect is good and more easy to maintain than drum brakes.
Present brake disc casting using side into mold by the way of water of casting, laterally enter water, stop after processing
Hull face stomata, slag blister defect, rejection rate is higher, especially when processing has the brake disc of ABS tooth, since ABS tooth mould is downward
Design, the tooth angle processed are easy existing defects, cause product quality not high.
Summary of the invention
It is an object of the invention to overcome the existing existing drawbacks described above of brake disc casting, a kind of brake disc gap is proposed
Pouring device, simple structure and reasonable design, brake disc disk stomata, the slag blister made are few, high yield rate.
The present invention, which is that the following technical solution is employed, to be realized:
A kind of brake disc gap pouring device, including upper sand mo(u)ld, upper sand mo(u)ld lower part are provided with the lower sand mo(u)ld adaptable with it,
The centre of upper sand mo(u)ld is provided with sprue, and sprue is through upper sand mo(u)ld and is deep into lower sand mo(u)ld, among upper sand mo(u)ld and lower sand mo(u)ld
It is provided with brake disc inner cavity, brake disc inner cavity is connected by lateral running channel with sprue；Intracavitary setting in the brake disc
There is outer core-skin, outer core-skin lower part is provided with precoated sand air duct core；The outer core-skin is arranged in upper sand mo(u)ld bottom, precoated sand air duct
Core is arranged at the top of lower sand mo(u)ld.
Brake disc gap pouring device is entered from lower sand mo(u)ld by sprue from top, is then entered from lateral running channel
Brake disc inner cavity is cast, and enters back into lateral running channel after flowing into sprue bottom, reduces the impact force of casting water, simultaneously
Be flowed into the speed of brake disc inner cavity more evenly, speed uniformly cast afterwards water temperature it is also more stable, then it is cooling when, water-setting of casting
Gu process is more balanced, the formation of stomata, slag blister is further reduced.
Further preferred, the casting core includes that outer core-skin, precoated sand air duct core and ABS gear ring mould, outer core-skin are set
It sets on precoated sand air duct core top, outer core-skin lower part is embedded into precoated sand air duct in-core, the setting of precoated sand air duct in-core upper lateral part
There is ABS gear ring mould；The described connor gate setting in precoated sand air duct in-core lateral roof, connor gate be connected to brake disc inner cavity and
Lateral running channel；The outer side-lower of connor gate is arranged in the ABS gear ring mould.
ABS gear ring mould designs upwards, and casting water can uniformly be flowed into ABS gear ring mould by connor gate when casting,
During ABS gear ring mould, gas can be discharged upwards, and multiple equally distributed connor gates cast water more evenly after flowing into
Be dispersed on ABS gear ring mould, situations such as being not in unfilled corner after the molding of ABS tooth, molding effect is more preferable.
Further preferred, the circle of precoated sand air duct core outer ledge one is evenly arranged with multiple radioactivity exhausts
Road；The radioactivity exhaust duct is arranged between upper sand mo(u)ld and lower sand mo(u)ld, radioactivity exhaust duct connection outside and precoated sand wind
Road core.Radioactivity exhaust duct is communicated with precoated sand air duct core, after water of casting enters brake disc inner cavity from bottom, in brake disc
Intracavitary air can be with the discharge of precoated sand air duct core radiotropism exhaust duct be gradually passed through, and radioactivity exhaust duct is uniformly arranged, really
Exhaust process stable and uniform is protected, prevents the formation of internal porosity, slag blister, it is ensured that brake disc quality.
Further preferably the outer core-skin includes embedded division and forming part, and embedded division is arranged in precoated sand air duct core
Top surface, forming part are deep into sand mo(u)ld.
Further preferably the embedded division is elongated, and both sides of the edge and precoated sand air duct core are adapted, before embedded division
The size of two sides is less than precoated sand air duct core afterwards.Outer core-skin embedded division front and rear sides are less than the size of precoated sand air duct core, overlay film
The venting quality of sand air duct core is more preferable, and preferably gas intracavitary in brake disc can be discharged by radioactivity exhaust duct, so that
It is less to pour brake disc stomata, the slag blister cast out.
Further preferred, the connor gate is provided with eight.
It is further preferred, the wide 20mm, high 3mm in the radioactivity exhaust duct section.
The beneficial effects of the present invention are:
(1) brake disc gap of the present invention pouring device is cast by the sprue being arranged on upper sand mo(u)ld, is poured
Water intracavitary diffusion into brake disc from centre is cast, when diffusion is internally flowed more evenly, while when water of casting flows inward into, internal
Bubble is spread out more easily by sand mo(u)ld, and the brake disc quality made is higher.
(2) brake disc gap of the present invention pouring device is enclosed by precoated sand air duct core outer ledge one and is uniformly set
Multiple radioactivity exhaust ducts are equipped with, internal gas can further be discharged, reduce the formation of stomata, slag blister, improve casting
Brake disc quality out.
(3) brake disc gap of the present invention pouring device, is provided with ABS gear ring mould, and when casting, casting water is from top
It flows into after lateral running channel and ABS gear ring mould is entered by connor gate, when casting casts water flow velocity relatively more evenly, can cover completely
It covers on ABS gear ring mould, therefore pours the ABS gear ring cast out and be not in unfilled corner, lack the problem of side, quality is higher.
(4) brake disc gap of the present invention pouring device, outer core-skin front and rear sides are less than the ruler of precoated sand air duct core
Very little, the venting quality of precoated sand air duct core is more preferable, can preferably arrange gas intracavitary in brake disc by radioactivity exhaust duct
Out, so as to pour the brake disc stomata, the slag blister that cast out less.
