Description
Technical field
The utility model is related to a kind of sandboxes for preventing casting-up from running away.
Background technology
Usual sandbox prevents the contact firmly of casting mold faying face from damaging casting mold by pressure in mould assembly mould assembling using mud cream, envelope type mud item etc.
Sand is squeezed, gap is formed between casting mold faying face；Pouring metal melt is filled with casting mold, and casting mold faying face is due to molten metal pressure, combination
The variation of face gap size, molten metal are easy to cause to run away from being forced out casting mold between casting mold combination gap.
Utility model content
The purpose of this utility model is that overcoming defect existing in the prior art, providing one kind prevents casting-up from running
The sandbox of fire, the problem of capable of being unreeled after mould assembling to block mould assembling die joint, admirably casting-up be prevented to run away, and
The winding work of flexible closure part can be realized in manual rotation after casting mold, can recycle.
To achieve the above object, the technical solution of the utility model is a kind of sandbox for preventing casting-up from running away of design,
Cope body and drag box body including being in shell structure, every piece of side plate its underpart of cope body are arranged for storing flexibility
The cavity of closure member, cavity are inclined cuboid, the hatch frame of wall setting flexible closure part, drag box in cope body
It is arranged for making flexible closure part be close to the pumping hole of wall in drag box body on the side plate of body；The side plate of cope body and drag box body
On be respectively provided with note sand hole, in cope body setting be fixedly connected in cope body the case plate washer on wall, note sand hole is located at cavity
Top；Hanging axis is fixedly installed on the lateral wall of cope body and drag box body.Due to the setting of flexible seals, sand is being filled in this way
When flexible seals blocked the die joint at upper and lower mould assembling, molten metal when being forced out casting mold between casting mold combination gap from can prevent
Only molten metal is run out of out of sandbox.The setting for taking out hole then ensures that flexible seals are close to sand cabinet wall when filling sand.
Further technical solution is the Scroll of rotation setting flexible closure part, one end of flexible closure part in cavity
It being fixedly connected on Scroll, the other end is fixedly connected for making flexible closure part decline to block the weight of mould assembling die joint,
The two side of cavity is arranged and the matched axis hole of Scroll, and setting winding drive shaft at axis hole is located on its side plate of cope body
Hole, the hatch frame includes the opening that sidewall bottom is arranged in cope body, the notch that is arranged on the plate of cope side and with
The matched baffle for preventing flexible closure part from declining of notch；The sandbox further includes for receiving flexible closure part after casting mold
The winding drive shaft of volume is matched with winding drive shaft hole；The end of the winding drive shaft is equipped with cuboid protrusion, described
One end towards winding drive shaft hole of Scroll is equipped with the rectangular channel for connecting winding drive shaft, rectangular channel and cuboid
Protrusion matching.
Further technical solution is that flexible closure part is heat-resisting for the plastic foil of surface coating refractory coating or surface coating
The non-woven fabrics of coating；It is respectively provided with flexible sealing plug at the notch, pumping hole and winding drive shaft hole；The cope body and lower sand
Babinet is rectangular case structure.The setting of refractory coating ensure that flexible seals will not be by boiling hot when filling sand and casting mold
Molten metal or the sand of heating scorch.Flexible sealing plug ensure that the leakproofness of entire sandbox.
Action process is as follows：, with after empty drag box body mould assembling, the slot of cope body will be pulled out after empty cope body mould turnover
Baffle is pulled out after flexible sealing plug at mouthful, exposes opening in this way, flexible seals in the presence of weight due to being down to drag box
Body medium position can block the die joint (initial stage can set the length of flexible seals) at upper and lower mould assembling, so in this way
The flexible sealing plug of drag box body drawn hole, connection negative pressure pump pumping so that flexible seals are close to sandbox body as possible are pulled out afterwards
Then inner wall starts to fill sand, fill the die joint after the completion of sand up and down at mould assembling and then blocked by flexible seals perfection, do not have to worry
Molten metal is run out of (although being closed there is also upper and lower out of sandbox from can prevent molten metal when being forced out casting mold between casting mold combination gap
Quadrangle is a leak source that may be present at case, but the possibility that can be run away is extremely low, or can be in the lower part of cope body four
With adjacent side plates in the cavity of 45 ° of fixture, inside setting such as above structure, i.e. flexible seals etc. ensure in this way for setting at angle
Without dead angle, molten metal can be entirely prevented to run out of sandbox from the die joint of upper and lower mould assembling place).Molding sand is poured out after the completion of casting mold,
Then the flexible sealing plug of winding drive shaft hole is pulled out, being inserted into winding drive shaft makes it in winding axis connection, then manually turns
The dynamic winding that flexible seals can be realized first is inserted into baffle and extracts winding drive shaft again after the completion of winding, then each beyond the Great Wall
Flexible sealing plug can be recycled next time.
The advantages of the utility model and advantageous effect are：The utility model passes through the setting of flexible closure part, Neng Gou
The problem of being unreeled after mould assembling to block mould assembling die joint, admirably casting-up be prevented to run away, and pass through after casting mold
It is inserted into the winding work that flexible closure part can be realized in winding drive shaft manual rotation, can be recycled；Due to flexible sealing
The setting of part, when filling sand, flexible seals have blocked the die joint at upper and lower mould assembling in this way, and molten metal is from casting mold combination gap
Between can prevent molten metal from being run out of out of sandbox when being forced out casting mold.The setting for taking out hole then ensures that flexible seals are tight when filling sand
Paste sand cabinet wall.The setting of refractory coating ensure that flexible seals fill sand and when casting mold will not by boiling hot molten metal or
The sand of heating scorches.Flexible sealing plug ensure that the leakproofness of entire sandbox.
