Description
Technical field:
The present invention relates to a kind of negative pressure evanescent mold sand box being provided with wicket, it belongs to casting technology field.
Background technology:
Technology of EPC is to be combined into model cluster by bonding for similar for casting dimension shape foam type, after brushing fireproof coating and drying, being embedded in vibration molding in drystone sand, cast makes model gasify under negative pressure, liquefaction metal occupies modal position, forms the novel casting method of foundry goods after solidification cooling.It, with the outstanding advantages such as the dimensional accuracy height of foundry goods, any surface finish, of low pollution, more traditional foundry engieering, has powerful competitiveness, is described as the foundry engieering of 21st century, the Green revolution of foundary industry.
But Technology of EPC just develops soon at home, producer, the improvement in the structure of the disappearance loft in Technology of EPC and each work package is being carried out different trials always, is explained below a kind of for the improvement opportunity done by the sandbox used by existing negative pressure lost foam.
Summary of the invention:
The present invention provides a kind of negative pressure evanescent mold sand box being provided with wicket, and it can effectively improve the performance of existing negative pressure evanescent mold sand box.
The present invention adopts the following technical scheme that a kind of negative pressure evanescent mold sand box, and it includes left wall, right wall, antetheca, rear wall and diapire, in described left wall, right wall, antetheca, rear wall is respectively formed with through hole that is that a row arranges along the vertical direction and that run through described negative pressure evanescent mold sand box wall, on diapire, also it is formed with the through hole arranged along the longitudinal direction simultaneously, first cylindrical hole running through described negative pressure evanescent mold sand box wall it is respectively formed with, in the left wall of described negative pressure evanescent mold sand box in the both sides of described each exhausting hole, right wall, antetheca, the outer surface of rear wall and diapire is respectively welded the channel-section steel of cross shape, the direction of the longitudinal extension of described channel-section steel is consistent with the orientation of through hole, transversely extending direction is consistent with the orientation of the first cylindrical hole, outer surface at described channel-section steel is formed with one second cylindrical hole, by described through hole, first cylindrical hole, groove in second cylindrical hole and channel-section steel enters as negative pressure ventilation pipeline, and the antetheca of described negative pressure evanescent mold sand box is additionally provided with two wickets reserved for sand.
There is advantages that on negative pressure evanescent mold sand box wall antetheca, offered two wickets, after sand can be flowed out by wicket, then foundry goods is hung out again, it is to avoid mould turnover when taking out sand and foundry goods, to cause the damage of sandbox, and then the service life of sandbox can be extended.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that the present invention is provided with the negative pressure evanescent mold sand box of wicket.
Wherein:
Left wall-10;Right wall-20;Antetheca-30;Rear wall-40;Diapire-50;Through hole-60;First cylindrical hole-70;Channel-section steel-80;Second cylindrical hole-90;Wicket-100.
Detailed description of the invention:
Refer to shown in Fig. 1, negative pressure evanescent mold sand box of the present invention is the body structure of hollow form, this negative pressure evanescent mold sand box includes four outer walls, and it is respectively defined as left wall 10, right wall 20, antetheca 30, rear wall 40 and diapire 50, left wall 10, right wall 20, antetheca 30, rear wall 40 are respectively formed with the through hole 60 running through described negative pressure evanescent mold sand box wall that a row arranges along the vertical direction, on diapire 50, are also formed with the through hole 60 arranged along the longitudinal direction simultaneously.First cylindrical hole 70 running through described negative pressure evanescent mold sand box wall it is respectively formed with in the both sides of this exhausting hole 60.Left wall 10 in described negative pressure evanescent mold sand box, right wall 20, antetheca 30, the outer surface of rear wall 40 and diapire 50 is respectively welded the channel-section steel 80 of cross shape, the direction that wherein longitudinal direction of channel-section steel 80 extends is consistent with the orientation of through hole 60, the direction that horizontal direction extends is consistent with the orientation of the first cylindrical hole 70, wherein it is formed with one second cylindrical hole 90 at the outer surface of channel-section steel 80, by through hole 60, first cylindrical hole 70, groove in second cylindrical hole 90 and channel-section steel 80 and then the breather line as negative pressure, it is installed on the channel-section steel 80 outside negative pressure evanescent mold sand box simultaneously and can also play the effect of sandbox reinforcement.
Being additionally provided with two wickets 100 on the antetheca 30 of negative pressure evanescent mold sand box of the present invention, then sand hangs out foundry goods, it is to avoid mould turnover to cause the damage of sandbox when taking out sand and foundry goods, and then can extend the service life of sandbox after can passing through the outflow of this wicket 100 again.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be regarded as protection scope of the present invention.
