Description
Technical field
The invention belongs to casting technology fields, are related to a kind of clearance type rising pouring pressurization system for casting and pouring, and in particular to arrive
A kind of clearance type, rising pouring, Quench, pressurizing processes design aluminium alloy castings application, in aluminum alloy gravity casting and anti-gravity
There is application in casting process.
Background technique
Gravity foundry technology design, by pouring type, can be divided into top pouring type, bottom filling, side note formula etc., most common category
Bottom filling.The Design of Runner System of gravitational casting includes: sprue, cross gate, ingate, riser etc., and sprue design is mostly
Circle presents bocca structure lower greatly, is typically located at the end or side of casting, and cross gate section is trapezium structure, generally
It is arranged in the side of casting, ingate section is flat trapeze structure, is typically located at casting bottom surface or side, riser is arranged in
The top surface of casting or thick big position.Antigravity casting technological design based on bottom filling, Design of Runner System include: sprue,
Cross gate, ingate.Sprue section is circle, is arranged in the lower section of cross gate.Cross gate section is arranged in casting to be trapezoidal
Lower section, below connected with sprue above connected with ingate.Ingate is arranged in casting in the following, upper end connects down with casting
End is connected with cross gate, and the shape of ingate can be round or trapezoidal according to the structure determination of casting.
The technological design of heavy castings mostly uses gravitational casting or antigravity casting for many years.Gravity casting and pouring system
Fig. 1 and Fig. 2 are shown in design；By taking cylinder cap as an example, 1 is casting；It is upper plane that the thick big position of casting is chosen in technological design.2 be riser；It emits
Mouth is arranged in the top of casting, and in up big and down small trapezium structure, the riser that the feeding of casting relies primarily on top is realized.3 are
Cross gate；Cross gate is arranged in the two sides of casting, and section is trapezium structure, plays undertaking sprue molten metal and connects ingate
Effect.4 be sprue；Sprue is arranged in the end of casting, and sprue upper end is used to accept the molten metal of sprue cup, lower end and
Cross gate connection.5 be ingate；Ingate is arranged in casting down either side, and section is in flat trapeze structure, and ingate one end connects
Cross gate is connect, the other end is connected with the bottom surface of casting.
The characteristics of running gate system: two sprues, two cross gates, which can be realized, quickly fills type, reduces ingate overheat and produces
Raw shrinkage defect, riser play feeding and dross, and gravitational casting operating instruction is easy, is not limited by casting equipment, raw
It produces high-efficient.
There are problems: easily there is nest stream in round sprue, increases the probability of secondary slag making, easily formation dreg defect；It is horizontal to pour
Road is limited to casting bottom feeding effect, and rarefaction defect easily occurs in casting, reduces performance indicator.
For the performance indicator for stablizing cylinder cap, the probability of secondary slag making is reduced, uses antigravity casting technological design, bob-weight
Fig. 3 and Fig. 4 are shown in the design of power system for casting and pouring；1 is casting；The placement direction of casting is consistent with gravitational casting.3 pour to be horizontal
Road；Cross gate is arranged in the lower section of casting, connects below cross gate with sprue, above connected with ingate, cross gate is
The position of trapezium structure and all ingates of covering, the section of cross gate are greater than the section of ingate.5 be ingate；Ingate
The top for being arranged in cross gate is connected with casting.4 be sprue；Sprue is circular arrangement in the lower section of cross gate, for holding
The molten metal of stalk is connect, sprue section is greater than cross gate section.
The characteristics of antigravity casting: the principle of antigravity casting is that crucible inner metal liquid passes through liter liquid under the influence of gas
Pipe, which enters sprue, cross gate, ingate, to be completed to fill type, since sprue, cross gate, ingate are all disposed within the lower section of casting
There is no casting drops, therefore it is steady to fill type.Due to sprue section > cross gate section > ingate section, in the work of pressure
With lower achievable consecutive solidification, since the entire process of setting of casting is to complete under stress, the casting of cast structure force of gravity
Dense structure is made, cast properties index is higher than the performance indicator of gravitational casting.
There are problems for antigravity casting: the casting process of antigravity casting is completed by low-pressure die casting plant, because
This casting preparation force of gravity casting is more, and casting will be overcharged the processes such as type, pressure stabilizing, pressurization, pressure maintaining, be poured big with the time
In gravity-assist pouring with the time, therefore production efficiency is lower, since the solidification of molten metal is to complete under pressure, makees in pressure
It is contacted for a long time with lower molten metal and casting mold, easily causes cast(ing) surface Sand Penetration, reduce the surface roughness of casting.
