Description
Technical field
The utility model relates to a kind of casting device, specially a kind of fixed point plug atmospheric feeder construction.
Background technique
During casting broken wearing piece circular cone liner plate, it has been found that due to special and working face point of casting structure
Cloth, initial technological design is very conservative in terms of feeding a casting, and riser height is very high, and product yield is low.Riser height means
Sandbox must be increased, and molten steel amount increases, and it includes labour cost, the electricity charge, alloy loss, export license, steel scrap etc. a system that this is intermediate
The waste of the manpower and material resources of column.
Summary of the invention
Existing use riser is excessively high in the process in order to solve to cast broken wearing piece circular cone liner plate for the utility model, feeding
The problem of low efficiency, provides a kind of fixed point plug atmospheric feeder construction.
The technical solution of the utility model is a kind of fixed point plug atmospheric feeder construction, including by feeding part, fever
Thermal insulation material type chamber, thermal insulation material lid, the feeding part connect heat preservation material type chamber, and heat preservation material type is intracavitary
Equipped with molten steel, it is equipped with fixed point plug hole in heat preservation material type chamber side, pinpoints in plug hole and is inserted with ventilation rods core, it is described
Ventilation rods core innermost end is located at heat preservation material type chamber center, and ventilation rods in-core is equipped with breather cord, heat preservation material
Type chamber is equipped with thermal insulation material lid, and thermal insulation material lid is equipped with gas vent.
One end of plug is placed on riser position by device described in the utility model, i.e. heat preservation material type chamber
Center and the final solidified most thermal potential of molten steel are set, and the other end is communicated with the atmosphere by ventilative plug, using atmospheric pressure by riser
It is intracavitary that the molten steel of centre heat is pressed into type.To improve the feeding efficiency of riser.Ventilative plug had been not used in the past
Under state, riser has cooled down crust around this period, although there are also hot molten steel at riser center, is in vacuum state
It cannot achieve feeding.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- heat preservation material type chamber, 2- gas vent, 3- feeding part, 4- breather cord, 5- ventilation rods core, 6- fixed point
Plug hole, 7- thermal insulation material lid, 8- molten steel.
Specific embodiment
As schematically shown in Figure 1, a kind of fixed point plug atmospheric feeder construction, including by feeding part 3, heat preservation material type
Chamber 1, thermal insulation material lid 7, the feeding part 3 connect heat preservation material type chamber 1, are equipped in heat preservation material type chamber 1
Molten steel 8 is equipped with fixed point plug hole 6 in 1 side of heat preservation material type chamber, pinpoints in plug hole 6 and be inserted with ventilation rods core 5, described
5 innermost end of ventilation rods core be located at 1 center of heat preservation material type chamber, be embedded with breather cord 4 in ventilation rods core 5, generate heat
Thermal insulation material type chamber 1 is equipped with thermal insulation material lid 7, and thermal insulation material lid 7 is equipped with gas vent 2.
The bottom of the breather cord 4 is located inside ventilation rods core 5, and 4 requirement of breather cord cannot penetrate through ventilation rods core 5.
Using preceding preparation, fixed point plug hole 6 is first beaten on heat preservation material type chamber 1, position will meet the requirements；It will
A kind of ready straw rope of breather cord 4() it protrudes into the hole for burying ventilation rods core 5.Ventilation rods core 5 is internal made of casting model powder
There is the material of a large amount of holes.In operating process, ventilation rods core 5 is inserted into fixed point plug hole 6, notices that ventilation rods core 5 is inserted into
Length want moderate and meet the requirements, finally cover thermal insulation material lid 7.After casting, breather cord 4 is burnt nearly at a high temperature of molten steel
To the greatest extent, occurs air duct inside ventilation rods core 5, extraneous atmospheric pressure, which enters thermal insulation material center portion by ventilation rods core 5, to be made
Molten steel 8 is pressed by feeding part 3 by internal and external pressure balance.
It is exactly intuitively most that molten steel amount is saved, original process molten steel is 2015Kg, using fixed using this Feeding
Molten steel is 1820 Kg after the ventilative plug atmospheric feeder construction of point, and molten steel amount saves 195Kg, and product yield is by original
67.7% come is increased to 73.6%, improves 5.9 percentage points.The expense difference that thermal insulation material Level Change generates is 27 yuan/part,
That is every can save 27 yuan compared with original process on thermal insulation material.Labor hour, the original process used time about 35 ~ 40 minutes,
Atmospheric pressure pinpoints ventilative about 20 ~ 25 minutes plug used times, and worker shortens in working hour.In addition, thermal insulation material Level Change, top box
Height reduce, sand using amount (by calculating after mixed) saves about 104 yuan compared with original process.As above it calculates, uses fixed point porous core
Stick atmospheric feeder technology saves 861 yuan compared with original process.
