What does the point that Die Casting model designs have?

Mould bases A.

Level off of brightness of outside area demand, around model casing adds 2 to dig a hole, the attention should be added in the position that does not have mold insert, prevent spare parts drop out to come. B.

A.

Cooperate to be done each between casing of B board model 0.

1-0.

15, add at the same time do flying water fender to prevent aluminium to fly broken bits injures a person. C.

Be out of shape to prevent pattern plate, at least becomes 2 post that prop up, one is put in billabong awl, one be put in billabong awl above, notice to be not interfered with other part. D.

The mould adds 2-4 hold in the palm in the root manage the edge is held in the palm in mixing, the edge is held in the palm in best make it takes spacing. E.

Mould motherboard should be done, facilitate medicinal powder hot. F.

4 horn should cut the pattern horn, gelinzhu does not bump when preventing to install, g.

The nitrogen after locating the circle inside requirement of surface of the aperture inside the circle is ground is changed, and the edge gives modular way polish. H.

The length to billabong awl surface is equal to the cooling annulus bottom of position group appearance commonly makings cake ply. Secure this means of cooling annulus to have 2 kinds: Burn-in and add hot pressing to enter. I.

Billabong awl must do carry water to cool, and from 25-30mm of billabong awl surface.

J.

Aperture of 4 guide pillar should do mould bases prize model chamfer, deepness 8-10mm. K.

Mould bases must move qualitative processing, had better be the mould bases that forge hits. L.

Take to go to the lavatory inside of the model set a needle, stiletto can be added in mould surface, receive a few screw that do not have a head next, so convenient tear open outfit change set a needle. M.

Hoisting aperture is M30 at least deep of 45, coping at least 2.

N.

Buy catapult must be added outside do bedspring to keep jacket, prevent bedspring to be out of shape. O.

Of face of tower above mould bases and should want to add the post that prop up with the face of ground surface contact. 2.

Inside model, mold insert A.

Before postheat is handled, treatment does stress to handle. General aluminium alloy quenchs HRC45+/-1 ° C, zincic alloy quenchs HRC46+/-1-1 ° Cb.

Inside modular fits tolerance: Accomplish commonly be less than modular casing 0.

05-0.

08mm left and right sides, can take out easily with rings put modular casing. Thimble fits tolerance: Be more than the thimble clearance that is equal to 8mm 0.

05mm, be less than the thimble clearance that is equal to 6mm 0.

025mm. C.

Always inside mix squarely above the model the place of acute angle must wrap R0.

5mm above. D.

Redundant eye aperture uses modular face inside one word screw is blocked up dead. 3.

Flow path and cuttings pick-up system design A.

The mainstream path of cake of the fabrics on billabong awl should accomplish the 1/3 less than that round face accumulates. Prevent cold makings to be entered quickly so model cent face closed before antrum. B.

Mainstream path wants make it above billabong awl " W " appearance, makings cake ply accomplishs 15-20mm.

C.

The length that general main trend accomplishs 30-35mm, and a model that unilateral makes 5-10 ° . D.

General horizontal flow path had better be bend, and make it 2 step above, prevent cold makings to be entered through horizontal flow path model antrum, cause product appearance cold lie between grain. E.

The runner place that can enter a product to go out in horizontal flow path commonly adds 2 bumper best, block cold makings completely in so model outside antrum. F.

The thimble below path of average level mainstream expects should make a model, and above of R2 wanting a bag. G.

There is bulgy fuse to must keep away from on mainstream path, and the broken bits bag on mainstream path had better be to do rubbish to wrap first, depend next add again. H.

Broken bits includes the plane of best bully field, semicircular sectional appearance, and the place that enter water and air discharge duct should separate 1/3 best. The part entering water that broken bits includes also wants skip a grade. I.

Air discharge duct should be hit fold and glide wanting a circle is crossed, should abide by " 3.

2.

1 " regular. J.

For convenient treatment, runner of connecting part of straight flow path and product wants skip a grade, when be being machined after, not allow to drop the flesh easily. 4.

Cooling system A.

Billabong awl must do cooling carry water, prevent the chap with billabong premature awl so. B.

Runner is covered do cooling annulus to cool, fixed and cooling annulus has 2 kinds of kind: Burn-in to be entered with hot pressing. C.

Modular refrigeration should assure the following data inside, the diameter of carry conduit is general 8-10mm.

Carry water leaves the height of product lowest face: Aluminium alloy: 25-30mm.

Zincic alloy: 15-20mm.

D.

If inside modular carry water must walk along mould bases, must use high temperature resistant be able to bear or endure waterproof circle of high pressure. 5.

Smoke core orgnaization A.

Slide block must do aperture of model of a condole to be in up and down on 2 faces, convenient tear open outfit. B.

Slide block bottom should be done draw out makings chamfer, want at the same time wear-resisting make it the 8-12 Mm of face of mould bases of bottom of 2 prep above, clear when convenient production aluminous broken bits. C.

The layering of slide block should do wear-resisting chamfer, become 45 ° D with the direction that smoke core.

Slip orgnaization should guide Hua Ling lives, motion is smooth, cooperate clearance 0.

08--0.

12MM. E.

The slide block after combining a model and locking piece should impaction, osculatory area is less than 2/3, and have certain prestressing force.

When designing tool set, answer to undertake by undermentioned method and design program commonly: (1) considers to analyse product design, understand model requirement of utility, use state, exterior, especially requirement of precision of crucial position dimension and use plastic variety and shape technical properties. (2) presses model production lot, define the kind of tool set. Be like model batch is bigger, choose structure of stationary tool set; Model batch is lesser, use structure of movable type tool set. (3) conceives program of construction of a few kinds of moulds to undertake comparative, use make easily, facilitating operation, can ensure shape model the mould structure of character. According to model more or less do size, appearance and insert reach precision requirement, use tool set certainly or deliver a model, use enclosed tool set or half enclosed tool set structure. (Cent of 4) make choice of face. When choosing cent side, requirement of exterior surface roughness is subtler model face, scarcely should serve as cent face. (5) designs protruding, sunken model, want to undertake necessary dimension is calculated, tag tolerancepublic errand to want reasonable. (6) decides the model covers measure. According to designs punch and sunken model definite pattern is covered reach fixed head over all dimension, intensity wants appropriate. (7) determines oriented shape, design its size dimensions and installation to secure a method. (8) is affirmatory go up, way of lower mould orientation and configuration and dimension. (The electric power size that place of 9) computation tool set wants, design electric heat component. (Model of 10) design discharge and spare parts give modular shrink device, want do one's best to get power balanced. CNC Milling CNC Machining
