Abstract
The utility model relates to a kind of casting devices, more particularly, to a kind of novel hitch casting device, including sprue, and it is symmetricly set on sprue two sides and cross gate that one end is connected to sprue, the connection of one end of the cross gate other end and ingate, the hook body of ingate other end hitch to be cast are connected.Therefore, the utility model has the following advantages that：The utility model mainly avoid molten steel to gib head position wash away and the turbulent flow at this position, molten steel is set to stably enter gib head position, while coupler body position is located at entire casting system distal end, to avoid high-temperature region, reduce the casting flaws such as the shrinkage cavity at gib head position, it is ensured that coupler body position can form completely.
Description
Technical field
The utility model relates to a kind of casting devices, more particularly, to a kind of novel hitch casting device.
Background technique
In railway freight-car coupler coupler body Foundry Production, running gate system is that liquid metal is guided to enter the logical of type chamber in casting mold
Road.Its effect is：Control the speed of molten metal filling casting mold and full of the time needed for casting mold；Stably enter molten metal
Casting mold avoids turbulent flow and washes away to casting mold；Slag and other field trashes is prevented to enter type chamber；Non-involvement gas when casting, and
Make the principle for meeting consecutive solidification when casting is cooling as far as possible.Running gate system includes sprue cup, sprue, cross gate and interior pours
Road.
Existing frequently-used coupler hook body running gate system is to introduce molten steel, that is, end of the runner from coupler body lightening hole position
It is the lightening hole position of coupler body.Running gate system schematic diagram such as Fig. 1.However, existing running gate system can make molten steel impact gib head position
Molding sand, and this spot temperature is high, is easy to produce the casting flaws such as burning into sand, shrinkage cavity.Since gib head position is main force part,
Complex-shaped simultaneously, space is small, is difficult to clean up clean and repair welding to the defect at this position and handles.
Utility model content
The utility model is mainly the technical problem for solving gib head position casting flaw present in the prior art etc.；It provides
A kind of novel hitch casting device.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：
A kind of novel hitch casting device, which is characterized in that including sprue, and be symmetricly set on sprue two sides simultaneously
And the cross gate that one end is connected to sprue, one end connection of the cross gate other end and ingate, the ingate are another
The hook body of hitch to be cast is held to be connected.
The invention provides a kind of completely new coupler body running gate system, overall structure such as Fig. 2.Running gate system is closing
Formula running gate system, ingate are connected with hook body, and molten steel is made to enter coupler body from hook body position.Running gate system is using molding refractory brick
It manages sectionally assembled production, refractory brick tube is put into external mold after outer mold forming, while ingate uses open type end.
In a kind of above-mentioned novel hitch casting device, the sprue, cross gate and ingate are molding fire resisting
Pipe, sprue internal diameter areCentral point is 314.8mm apart from coupler body center line.
In a kind of above-mentioned novel hitch casting device, the ingate shape is loudspeaker open-type, loudspeaker open end with
Hook body is connected.
Therefore, the utility model has the following advantages that：The utility model mainly avoid molten steel to gib head position wash away and
The turbulent flow at this position makes molten steel stably enter gib head position, while coupler body position is located at entire casting system distal end, to keep away
High-temperature region is opened, reduces the casting flaws such as the shrinkage cavity at gib head position, it is ensured that coupler body position can form completely.
Detailed description of the invention
Fig. 1 is common running gate system schematic diagram.
Fig. 2 is the running gate system schematic diagram of the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.Its
In, gib head 1, hook body 2, hook tail 3, sprue 4, cross gate 5, ingate 6.
Embodiment：
The utility model includes sprue, and is symmetricly set on sprue two sides and cross that one end is connected to sprue
One end of running channel, the cross gate other end and ingate connects, and the hook body of the ingate other end hitch to be cast is connected
It is logical.Entire running gate system is using molding refractory brick tube production.
In the present embodiment, sprue is molding refractory tube, and internal diameter isIts central point is apart from coupler body center line
314.8mm.Sprue places mo(u)ld top half with pilot pin, and mo(u)ld top half is easy using pilot pin placement fever in ingate and cross gate junction
It cuts riser and carries out feeding.After mo(u)ld bottom half molding, sprue base is placed in sprue bottom, then place segmented refractory brick, combined
At ingate and cross gate.
In the present embodiment, ingate shape is loudspeaker open-type, to slow down molten steel flow velocity, reduces molten steel to hook body molding sand
Impact.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
