A kind of fruit juice mixer base mould
Technical field
The utility model relates to a kind of mould, relates in particular to fruit juice mixer and also claims mixer base mould.
Background technology
Produced fruit juice mixer in the past and claim that also the material of mixer base is a kirsite, but because the kirsite price is high in recent years, by original De $12,000/t increases to present De $34,000/t; At present all over the world to the strict demand of environmental protection, kirsite will progressively withdraw from food machinery in addition, and the material that replaces surely belongs to aluminium alloy for best, and except that various physical properties can match in excellence or beauty with kirsite, the from one piece cost reduced significantly.But when using existing mold also to claim the mixer base as raw material die casting fruit juice mixer with aluminium alloy, because high about about 580 ℃ of aluminium alloy fusing point, cast temperature during die cast is 620 ℃~710 ℃, its flowability differs greatly than kirsite, fill difficulty, and owing to the high hydrogen that has strengthened solution of temperature, mainly from atmosphere, suck hydrogen, simultaneously, because temperature height, the coating releasing agent fusing moment that is easy to be sprayed on die surface produces a large amount of gases, has increased to fill the probability that pore appears in resistance and part.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art a kind of fruit juice mixer base mould is provided.It can be raw material with the aluminium alloy, the fruit juice mixer base of die cast, and after polishing was electroplated, yields reached about 95%, can match in excellence or beauty with kirsite fully, and with the horizontal cold-chamber die casting machine production of 350~400T, class's output is 800~1000, and is also fully identical with kirsite.
The technical scheme of the utility model technical solution problem is: a kind of fruit juice mixer base mould, comprise sprue bush, branch flow cone, overfall, front mould, back mould, overflow launder and air discharge duct, it is characterized in that running channel is the fan type, ingate is that kiss gate combines with tangent gate, be that the central area is that flanging, both sides are tangent line, the kiss gate implant angle be 130 ° identical with the part angle.
Sprue for extending before the fan type running channel.
Described overflow launder cumulative volume is 25% of a part cumulative volume.
Air discharge duct is three sections, every section from inside to outside the degree of depth successively decrease.
First section degree of depth is 0.4~0.6mm, and second section degree of depth is 0.2mm, and the 3rd section degree of depth is 0.1mm.The sprue bush tapering is 6 °.
The overfall total sectional area is 70~75% of an ingate sectional area, and its overflow angle is 46 °.
Since the equal 1.7mm of this fruit juice mixer base wall Boping, the dark nearly 150mm in chamber is with respect to the surface quality requirement, quite difficult with aluminium alloy compression casting.For solving this difficult problem the utility model, take cooling to combine, with this balance mold temperature with heating.Mould promptly (fixed, dynamic model) is watering oral-lateral dress cooling water pipe, in front mould (cover half) cast gate opposite side heater is installed, back model core protrudes outside, radiating rate is very fast, do not install cooling water additional, but, cause mould cracking or be full of cracks too early for preventing the concentrations of alternating hot and cold stress, offer an eyebrow hole in the centre and be communicated with, naturally cooling with atmosphere
Running channel of the present utility model is the fan type, ingate is that kiss gate combines with tangent gate, and the central area is that flanging, both sides are tangent line, the kiss gate implant angle be 130 ° identical with the part angle, the injection resistance is little, speed is fast, has guaranteed effective filling of the dark cavity region in center; Tangent gate, resistance is big, and filling speed is slower, and effectively the flow process scope is little.Like this, both filling moldings when having guaranteed whole die cavity have been avoided the generation of eddy current.The overflow launder cumulative volume is about 25% of part cumulative volume, can fully assemble cold burden and die surface is dirty; 70~75% of overfall total sectional area ingate sectional area, its overflow angle is 46 °, like this, has guaranteed cold burden and dirty smoothly smooth and easy when entering overflow launder.Air discharge duct is three sections, and every section degree of depth is successively decreased, and has both guaranteed that exhaust is smooth and easy, guarantees that again raw material does not overflow.

Concrete case study on implementation
The utility model is described in further detail below in conjunction with accompanying drawing: a kind of fruit juice mixer base mould among Fig. 1, Fig. 2, Fig. 3, comprise front mould 1, back mould 2, sprue bush 3, overfall 4, overflow launder 5, air discharge duct 6 and running channel 7, it is characterized in that running channel 7 is the fan type, ingate is that kiss gate combines with tangent gate, be that the central area is that flanging, both sides are tangent line, the kiss gate implant angle is identical with the part angle.
Sprue 8 for extending before the fan type running channel 7.
Described overflow launder 5 cumulative volumes are 25% of part cumulative volume.
Air discharge duct 6 is three sections, every section from inside to outside the degree of depth successively decrease, first section air discharge duct degree of depth is 0.4~0.6mm, second section air discharge duct degree of depth is 0.2mm, the 3rd section air discharge duct degree of depth is 0.1mm.The sprue bush tapering is 6 °.
The overfall total sectional area is 70~75% of an ingate sectional area, and its overflow angle is 46 °.
Since the equal 1.7mm of this fruit juice mixer base wall Boping, dark chamber 150mm is with respect to the surface quality requirement, quite difficult with aluminium alloy compression casting.For solving this difficult problem the utility model, take cooling to combine, with this balance mold temperature with heating.Promptly water oral-lateral dress cooling water pipe 9 at front and back mould (fixed, dynamic model), in front mould (cover half) cast gate opposite side heater 10 is installed, back model core protrudes outside, radiating rate is very fast, do not install cooling water additional, but, cause mould cracking or be full of cracks too early for preventing the concentrations of alternating hot and cold stress, offer an eyebrow hole 11 in the centre and be communicated with, naturally cooling with atmosphere.
