Embodiment one
Referring to Fig. 1 (concrete structure can be found in Fig. 2, Fig. 3), the utility model embodiment one provides a kind of stop-off hanger,
Stop-off hanger body 100 and groove 200 including truncated conical shape；
The groove 200 is located on the upper bottom surface of the stop-off hanger body 100, and the extension of the groove 200 is square
Through the circle centre position of the upper bottom surface of the stop-off hanger body 100.
The primary structure for analyzing above-mentioned stop-off hanger is understood：The primary structure for analyzing above-mentioned stop-off hanger is understood：
It will be apparent that above-mentioned stop-off hanger, it mainly includes the stop-off hanger body 100 and groove 200 of truncated conical shape, with this
Meanwhile the groove 200 is located on the upper bottom surface of the stop-off hanger body 100, and the extension of the groove 200 square passes through
The circle centre position of the upper bottom surface of the stop-off hanger body 100.
The utility model provide a kind of stop-off hanger its, be it is a kind of according to casting design special stop-off hanger (even
Claim stop-off mud core).Stop-off mud core removes (and the stop-off hanger of truncated conical shape is easy to molding) during molding；Simultaneously because groove
Some sand amounts are stored in 200, so a part of space can be filled automatically being removed with mould rear lifting lug mud core, are thus shortened
Landfill and resin sand hardening time is waited, enhances processing efficiency,
The stop-off hanger can improve operating efficiency, reduce the time for the solidification for waiting resin sand, improve effective space
Utilization rate, filter efficiency is improved, improve product quality.
In addition, it is necessary to explanation, the stop-off hanger that the utility model embodiment provides, i.e. stop-off mud core, it has such as
The technical advantage of lower aspect：1st, simple in construction, manufacturing cost is low；2nd, lighter in weight, using flexible, suitable for various Big Steel Castings
Part；3rd, easy to operate, single worker can complete to operate after simple training；
Briefly explained on resin sand casting production operation processing step：
First, mould is arranged and checked
Check whether mould core box is complete, remove excessive residual deposit existing for mould core box surface.Check mold core
Whether box meets drawing requirement with the presence or absence of unfilled corner, deformation, size；Check whether loose piece, dead head are incomplete.Inspection alignment pin,
Whether hole coordinates suitable；Whether the installation of the die lifter and handling apparatus of mould is suitable.Check whether baffle plate is straight.6. sand
Whether case size is suitable；The chill of baking required for preparing, (must be cooled to room temperature after chill, stud baking can just make stud
With) molding hoist tool, breather cord, back-up sand sand lump.
2nd, sand and reality of pounding are added：Heavy castings should put sand since a certain angle of sandbox, and pay attention to adding for appropriate adjustment curing agent
Enter amount, extend the up time of resin sand.Want to consolidate in Fang Sha, contend from sandbox one and gradually continuously expand along the other directions of mould
Exhibition, until piling whole sandbox.For large space sandbox, it is necessary to assure cast gate, rising head, the resin sand at venthole position reach
The height of technological requirement, dead head, the highly usable riser sleeve etc. at venthole position reach technological requirement., should at the end of putting sand
Notice that tailings must not be placed on dead head, venthole position, can be only placed at unessential place.Due to resin sand mobility very
It is good, pound and only require that speed is fast in fact, but need not too exert oneself.The positions such as turning, groove have to reality of pounding.After sand is piled, strike off
Sandbox and core box and air tube bundle stomata.Passage must be conscientiously tied in moulding on top box for thick strip, wallboard part etc..Add
Sand lump or other fillers can be tamped because resin sand cost is higher further to reduce cost with antiquated sand block or other fillers
The unessential space of sandbox.There must not be space between filling sand lump, should consolidate.
3rd, molding：Resin sand slightly discoloration stickness, can extract rising head, down gate, outlet rod etc. after a few minutes.During molding
Between determination.When sand mold casehardening, internal layer have intensity but it is not fully hardened when molding.Stripping time controls good, is advantageous to
Protect apperance and accelerate sand mold hardening.Stripping time early wants very much crush；Too late, molding is difficult, is easily damaged apperance.
4th, repairing type：Need to repair position damaged after molding after molding.Specific requirement is as follows：1. because of molding
Band disconnected groove, turning or the declined sand lump of edges and corners, if monoblock is unbroken, the floating sand grains of fracture location need to be only blown, is used
Adhesive is clung again, clogs in its gap with coating in postorder swabbing.2. if the sand lump of breakage is broken
, newly mixed resin sand can be used to repair.Barb groove (or digging breakage big) is made before repairing, plugs nail, and blow off floating
Sand grains, then repaired with newly mixed resin sand.Unnecessary part is ground off with emery wheel after hardening.3. sand mold is damaged small or local
During the loose hole of sand mold, the painting slurry of stiff can be used to repair.Scraper will exert oneself coating being pressed into hole during repairing.It is 4. damaged
Locate the inspection of sand bond, can firmly be wiped with hand, will not knockout with mo(U)ld face.
5th, swabbing；
6th, the main points that coremaking should be noted that：3.3.1 the preparation of arbor；3.3.2 1. monoblock type core box a.'s coremaking key points for operation exists
It is put into core box to wind the arbor of breather cord, breather cord is drawn core print by adjustment each several part to rational mold thickness.By arbor
Suspension ring put in order, expose ramming face.Arbor should be less than ramming face certain thickness, this thickness with core it is of different sizes without
Together.Put sand and reality of pounding, sand strike off core box after piling.Core solidification plays core for a period of time and after reaching sufficient intensity.Answered when playing core
Find the center of gravity of core accurately, driving crawl plays core, and knocks core box with rubber hammer, and core should be quickly played after core disengaging.Core rises
It should be placed on soft sand pocket, and level up after go out, prevent core from deforming.2. split type core box a. cleans out core box, two
Half core box clamps.B. the arbor for being wound with enough breather cords is put into, the suspension ring of arbor expose ramming face, and breather cord exposes core print.Put
Sand and reality of pounding, sand strike off after piling.After core reaches sufficient intensity, core box clamping device is opened, opens two halves core box.Take out
Core, it is placed on soft sand pocket, and levels up, prevents core from deforming.For special shape loam core, vertically pound and reached enough
Level can be integrally placed after intensity together with core box, opens clamping device, takes out loam core.
7th, with mould：Empty mould assembling inspection：, must before lower core to ensure quality for initial workpiece, first batch of or important larger casting
Empty mould assembling must be carried out.During empty mould assembling, by long box pin insertion top box guide, positive sandbox position (pinhole pair is borrowed with driving
It is accurate), it is impossible to employment is drawn, pays attention to now nowel plane apart from surrounding should basically identical (otherwise should adjust), mould assembling speed will be slowly.
After mould assembling, examine die cavity situation, if having dislocation and upper nowel planar junction close it is uneven situations such as, confirmation meet the requirements after
Upper nowel die joint does three sights, is easy to check, if finding situation during empty mould assembling, should be contacted in time with technical staff, it is determined that
Solution method.Lower core：Lower core must be familiar with foundary methods drawing and technological requirement, understand between the basic structure of casting, sandbox and sand
The relative position of core and sand mold, sand mold quantity etc., prevent lower core position and direction make a mistake or leaked from putting core.
