Abstract
The utility model provides a gravity casting mold, including centre form, external mold and be built by contract, the external mold top is located to the be built by contract, just the runner that is equipped with a runner on the be built by contract and feeds through with this runner, the runner has a horizontal segment and vertical section, the centre form is worn to establish the be built by contract is arranged in in the external mold, form an annular die cavity between external mold and the centre form, the runner with the circumference surface of centre form is tangent, the lateral wall bottom of external mold is equipped with an exhaust hole. The utility model discloses a gravity casting mold simple structure, the feeding is even and casting quality production is high.
Description
Technical field
This utility model relates to a kind of mould, particularly a kind of gravity casting die.
Background technology
Gravitational casting is referred to pour into molten metal solution in the die cavity of mould and is formed by crystallization and freezing
The method of foundry goods, after the method makes metallic solution be full of mold cavity by action of gravity, crystallization and freezing forms casting
The process of part.
Cast gate is extremely important in casting design, flow when decide molten metal filling die cavity, speed,
Filling order and flow regime.In the ordinary course of things, during casting thin-section casting, the flow resistance in die cavity
Relatively big, cast gate is also adopted by relatively thin thickness, therefore has big resistance, therefore to have bigger filling gravity,
Guarantee reaches the gate velocity needed, gate design good, can provide one more to Foundry Production
Loose processing range, easily casts out castings；Otherwise, then higher percent defective can be caused, very
Scrap to mould.During general casting thin-section casting, cast gate is all arranged at above the sidewall of external mold, casting gold
Belonging to the dirtiest during liquid, the charging of whole die cavity is uneven, after crystallization and freezing molding corresponding with cast gate one
Side is easily formed every hole, easily affects the quality of foundry goods.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of simple in construction, and charging is uniform and raw
Produce the central gravity casting mould that casting quality is high.
This utility model is achieved in that a kind of gravity casting die, it is characterised in that: include interior mould,
External mold and clad；Described clad is located at outer mold top, and described clad be provided with a runner and with this stream
The cast gate of road connection, described runner has a horizontal segment and vertical section；Described interior mould wears described clad and puts
In described external mold, between described external mold and interior mould, form an annular die cavity；Described runner and described interior mould
Circumferential surface tangent；The sidewall bottom of described external mold is provided with a steam vent, for the sky of discharge type intracavity
Gas.
The utility model has the advantage of: by arranging runner and the cast gate with flow passage on clad,
And cast gate is tangent with the circumferential surface of interior mould, molten metal can be made to take advantage of a situation rotation along interior mould under gravity
Turn of tidal stream enters die cavity, forms center casting pattern, makes die feeding uniform, be difficult to shape after crystallization and freezing molding
Become every hole so that the quality of foundry goods is high, and percent defective is low.
Accompanying drawing explanation
This utility model is further described the most in conjunction with the embodiments.
Fig. 1 is the structural representation of this utility model gravity casting die.
Fig. 2 is the top view of Fig. 1.
Drawing reference numeral illustrate: interior mould 1, external mold 2, clad 3, runner 31, cast gate 32, horizontal segment 311,
Vertically section 312, die cavity 4, steam vent 21
Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2, this utility model one gravity casting die, including interior mould 1,
External mold 2 and clad 3；Described clad 3 is located at external mold 2 top, and described clad 3 is provided with first-class
Road 31 and the cast gate 32 connected with this runner 31, described runner 31 has a horizontal segment 311 with vertical
Section 312, described vertical section 311 connects with cast gate 32；Described interior mould 1 wears described clad 3 and is placed in
In described external mold 2, between described external mold 2 and interior mould 1, form an annular die cavity 4；Described runner 31
Tangent with the circumferential surface of described interior mould 1；Molten metal can be made to take advantage of a situation along interior mould 1 under the effect of the pressure
Rotation flows to die cavity 4, and charging is uniformly, and after high pressure cooling, foundry goods is not easily formed every hole；Described external mold 2
Sidewall bottom be provided with a steam vent 21, in molten metal is filled to die cavity, the air in die cavity can be by
The steam vent 21 of external mold 2 sidewall bottom is discharged, and reduces casting of appearance of cast flaw and dysplasia.
During by gravitational casting thin-section casting of the present utility model, cast gate is arranged at die cavity top, is formed
Center casting pattern, makes die feeding uniform, and after crystallization and freezing molding, foundry goods is not easily formed every hole so that
The quality of foundry goods is high, and percent defective is low.
Although the foregoing describing detailed description of the invention of the present utility model, but it is familiar with the skill of the art
Art personnel should be appreciated that our described specific embodiment is merely exemplary rather than for right
The restriction of scope of the present utility model, those of ordinary skill in the art are according to spirit of the present utility model
The modification of the equivalence made and change, all should contain of the present utility model claimed
In the range of.
