The utility model purpose, which is to provide, a kind of to be used to cast the caliper that horizontal modeling formula focus is scattered in bridge portion both sides
Model structure, it can solve the problem that the deficiencies in the prior art, for above-mentioned yield rate and shrinkage porosite problem, pass through thermal-insulating scheme and rising head
Design, Feeding channel is opened between making the scattered focus of cast-internal, and then allows single rising head effectively to reach the benefit of plural focus
Contracting, avoids the shrinkage porosite of cast-internal, shrinkage cavity bad, reaches the stable lifting with yield rate of product quality.
The technical solution of the utility model：It is a kind of to be used to cast the caliper mould that horizontal modeling formula focus is scattered in bridge portion both sides
Type structure, it is characterised in that it is by sprue cup, sprue, cross gate, strainer core, laterally divides running channel, enters water piece, rising head, emits
Mouth neck, heat-insulation system and casting die cavity are formed, and the sprue cup connects sprue；The vertical direction connection of the sprue is horizontal
Running channel；Running channel is laterally divided in the cross gate end by strainer core connection；The strainer core and cross gate and the running channel is laterally divided to be
It is arranged in parallel；The transverse direction divides running channel to connect rising head by entering water piece, and each rising head connects a casting die cavity by riser neck；
Each casting die cavity sets heat-insulation system respectively on the inside of casting with tail end, is connected on rising head and casting；Each casting
Die cavity and rising head are all independently to enter water system.
The sprue cup is taper, and bottom completely overlaps with sprue.
The sprue vertical direction connects two cross gates, and the end of two cross gates is connected laterally by strainer core
Divide running channel.
The cross gate is with laterally dividing running channel section to be all symmetrical trapezium structure；It is described enter water piece be thin rectangular shape knot
Structure；The rising head is shaped as cylinder, and riser neck is shaped as cone.
The course of work of the present utility model：The horizontal modeling formula focus of this casting is scattered in the caliper model structure of bridge portion both sides
Including two block models, model carries out matched moulds after sand mo(u)ld is printed in moulding, and molten metal enters along sprue cup, sprue, cross gate
Enter strainer core, by entering the order filling casting die cavity for laterally dividing running channel, entering water piece, rising head, riser neck after strainer core, it is poured
The note time must be controlled within 12 seconds, it is ensured that and casting meets demand with rising head temperature, to reach graphite expansion feeding effect,
Avoid the generation of shrinkage porosite.
Superiority of the present utility model：This model structure uses free-standing feeding system, passes through setting for heat-insulation system
Meter makes Feeding channel in casting keep unimpeded, interconnects the focus of discrete areas, and effectively each region can be carried out for rising head
Feeding, substitute traditional scheme Feeder Design, the yield rate of product can be effectively improved and avoid rising head interfere with each other produced by it
Shrinkage porosite.
(4) illustrate：
Fig. 1, which is that the utility model is involved, to be used to cast the caliper model structure that horizontal modeling formula focus is scattered in bridge portion both sides
Structural representation.
In figure：1 is sprue cup, and 2 be sprue, and 3 be cross gate, and 4 be strainer core, and 5 is laterally divide running channel, 6 be into water piece,
7 be rising head, and 8 be riser neck, and 9 be heat-insulation system, and 10 be casting die cavity.
(5) embodiment：
