Abstract
The invention discloses a wallboard casting inner die, which comprises an inner die body and a plug, wherein the inner die body comprises an upper left inner die strip, a lower left inner die strip, an upper right inner die strip and a lower right inner die strip; the left side of the upper left inner die strip is connected with the left side of the lower left inner die strip through a left elastic sheet; the right side of the upper right inner die strip is connected with the right side of the lower right inner die strip through a right elastic sheet; the right lateral surface of the upper left inner die strip is adapted with the left lateral surface of the upper right inner die strip; the right lateral surface of the lower left inner die strip is adapted with the left lateral surface of the lower right inner die strip; and the plug is arranged in an annular middle encircled by the upper left inner die strip, the lower left inner die strip, the upper right inner die strip and the lower right inner die strip. The wallboard casting inner die has the advantages that: stripping can be performed at any time after a wallboard gelled material is solidified, the inner die is integrally produced, the arrangement of labor force provides enough time, and the inner die is durable, can be quickly assembled and quickly stripped and can save labor during wallboard casting so as to reduce the cost.
Description
Technical field
The present invention relates to a kind of wallboard casting internal mold.
Background technology
One of them index of wallboard is a lightweight; In order to alleviate the weight of wallboard; Generally be employed in and some lightening holes be set in the middle of the wallboard, and the method for making these lightening holes all is in the casting wallboard, to put into internal mold, again internal mold is taken out after waiting casting material to solidify and form.The mould that is used for the wallboard internal mold at present has three kinds: the one, and the iron and steel pipe is done internal mold, the duration and degree of heating of GPRS tube drawing, tube drawing because pours does not also have initial set, cause the mould that collapses too early, and wallboard is scrapped; Cross slow tube drawing, be used for the wallboard cementitious material and the iron and steel pipe bonds together, form steel concrete, the iron and steel pipe can not be extracted; The 2nd, do internal mold with hollow engineering plastics, because plastics have certain shrink property, this internal mold solidifies the back fully in the wallboard cementitious material pulls out with the elevator function, but application life is not long, weares and teares after general 1 year and scraps; The 3rd, use the steel plate flanging, form middle 6 up and down, assembles 6 flanging steel plates in order earlier before the wallboard cast, form an integral body; Pour into a mould then, solidify the back and earlier be 6 to the internal mold dismounting, piecemeally then from lightening hole, extract the completion demoulding; The advantage of this internal mold is as the engineering plastics internal mold, need not grasp the duration and degree of heating of tube drawing, and solidifying the back any time can the demoulding; Shortcoming is that the demoulding and internal mold assembling are too time-consuming, and production efficiency is low, and cost of production is high.
Summary of the invention
The object of the present invention is to provide a kind of wallboard casting internal mold, can effectively solve interior moulding/demoulding of existing wallboard and assembling wastes time and energy the problem that production efficiency is low, cost of production is high.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: a kind of wallboard casting internal mold; Comprise interior mould body, stopper; Mould body comprises upper left internal mold bar, left core insert bar, upper right internal mold bar, bottom right internal mold bar in said; The left side of said upper left internal mold bar is connected with the left shell fragment of passing on left of left core insert bar, and the right side of said upper right internal mold bar is connected through right shell fragment with the right side of bottom right internal mold bar, and the left surface of the right flank of said upper left internal mold bar and upper right internal mold bar is suitable; The left surface of the right flank of said left core insert bar and bottom right internal mold bar is suitable, and said stopper is arranged on the centre of the annular that upper left internal mold bar, left core insert bar, upper right internal mold bar, bottom right internal mold bar surround.
Preferably, an end of said left shell fragment is welded on the left surface of upper left internal mold bar, and the other end of said left shell fragment is welded on the left surface of left core insert bar; One end of said right shell fragment is welded on the right flank of upper right internal mold bar, and the other end of said right shell fragment is welded on the right flank of bottom right internal mold bar; Adopt the mode of welding to connect, technology maturation is stable, firm and reliable connection.
Preferably; The left surface of said upper right internal mold bar is inside inclined-plane; The inclined-plane that the side of the side of said upper left internal mold bar and upper right internal mold bar is suitable; Said left core insert bar and upper left internal mold bar are about axial symmetry in the level, and said bottom right internal mold bar and upper right internal mold bar are also about axial symmetry in the level; Conveniently stripped, make the left side inner formword tight with being connected of right side inner formword.
Preferably, said left shell fragment is provided with the cross through hole mould; Said right shell fragment is provided with the cross through hole mould; Can let cross through hole cast with lightening hole finishes.
Preferably, the external surface of said upper left internal mold bar, left core insert bar, upper right internal mold bar, bottom right internal mold bar, left shell fragment, right shell fragment all scribbles mold oil; The difficulty that mould body separates from casting matrix in reducing.
Preferably, the external surface of said upper left internal mold bar, left core insert bar, upper right internal mold bar, bottom right internal mold bar, left shell fragment, right shell fragment all is coated with separating layer; Make things convenient for internal mold from the casting matrix of finalizing the design, to separate.
Preferably, said separating layer is PE film or PP film; Cheap, coat separating layer easily, as long as PE film or PP film are wrapped in the interior mould body outside.
Compared with prior art, advantage of the present invention is: because the release method of this internal mold is not to lean on the sliding friction hard draw, only inner mould inwardly draw in the disengaging that does not have to accomplish under the sliding friction prerequisite internal mold and wallboard lightening hole inwall; Any time after the wallboard cementitious material is solidified can the demoulding, is production, and the arrangement of labour provides the well-to-do time; Internal mold and wallboard lightening hole inwall do not have sliding friction, so internal mold does not almost have loss in the demoulding, internal mold is durable in use; Can assemble fast and fast demoulding, when wallboard is poured into a mould, can practice thrift recruitment, thereby reduce cost; Need not lean on the machinery or the demoulding of manpower hard draw, alleviate the labour intensity of the demoulding greatly, improve work efficiency; Internal mold of the present invention is made through folding brake repeatedly with steel band, has higher self intensity, so be suitable for very much mechanization production.
