Abstract
The invention discloses a briquette coal mold capable of improving the product rate of a coal sample. The briquette coal mold comprises a pressuring column and a forming mold, wherein the forming mold is of a splitting type structure; the forming mold is of a cylinder structure which is composed of 2-3 circular-arch-shaped assemblies and with a sealed bottom and an open top; fastening sleeve rings are further arranged; the inner diameter of each fastening sleeve ring corresponds to the outer diameter of the forming die; and one fastening sleeve ring is arranged at each of the upper part and the lower part of the forming die. The forming mold with the splitting type structure is adopted and the forming mold is fixed through the fastening sleeve rings, so that the mold is effectively fixed in a forming process and the coal sample can be taken out in a manner of detaching the forming mold; the problem that the coal sample which is prepared by a traditional briquette coal mold is easily damaged in a de-molding process is avoided; and an outer compression column outer sleeve ring and a forming mold inner sleeve ring are matched, so that the briquette coal mold is suitable for preparing coal samples with different sizes and experiment cost can be effectively saved. The briquette coal mold can be detached and transported so that the transportation difficulty is also remarkably reduced.
Description
Technical field
The present invention relates to coal sample technical field of mold, a kind of moulded coal mould that can improve coal sample ratio defective product.
Background technology
At present, when carrying out coal sample experiment, the coal sample used needs first molding, use again, the mould of molding coal sample is referred to as moulded coal mould, and the moulded coal mould commonly used now is the most all the metallic article of fixed dimension, these moulded coal mould not only weight are big, it is not easy to carrying, and the product of molding single size, made coal sample can only easily damage in knockout course and cause that substandard products occur, therefore the defect rate of product is high so that it is bring a lot of inconvenience in actual applications, can cause a large amount of wastes of coal sample.
Summary of the invention
It is an object of the invention to: providing a kind of and can improve the moulded coal mould of coal sample ratio defective product, it can significantly improve coal sample yield rate, to overcome the deficiencies in the prior art.
The present invention is achieved in that the moulded coal mould that can improve coal sample ratio defective product, and including pressured column, shaping mould, shaping mould is split-type structure, and shaping mould is formed a bottom lock, the cylindrical structure of open top by 2-3 circular arc assembly；Being additionally provided with collar, the internal diameter of collar is corresponding with the external diameter of shaping mould, respectively sets a collar on the top of shaping mould and bottom.
Being externally provided with pressured column outer sleeve at pressured column, be provided with shaping mould inner sleeve in shaping mould, the external diameter of shaping mould inner sleeve is corresponding with the internal diameter of shaping mould, and inner sleeve is cylindrical structure and its open at both ends of split-type；The internal diameter of pressured column outer sleeve is corresponding with pressured column external diameter.
Described pressured column outer sleeve and shaping mould inner sleeve are more than one group, and often group pressured column outer sleeve is collocated with each other use according to ascending descending with the size respectively shaping mould inner sleeve of size.
For threadeding between shaping mould with collar.Conveniently removing and installing, and connect and fixing good reliability, in order to ensure the fastening after screwing in, the outer wall of shaping mould can use two ends smaller, and middle bigger outer wall construction makes collar in screwing operations, can increase fastening effect.
Being provided with limiting card on the inner chamber top of shaping mould, the outer wall at shaping mould inner sleeve is provided with stopper slot, and stopper slot is corresponding with limiting card position.
Owing to have employed technique scheme, compared with prior art, the present invention uses the shaping mould of split-type structure, shaping mould is fixed, it is ensured that mould during molding obtains the most fixing, and coal sample can be taken out by the way of taking shaping mould apart by collar, avoid the problem that the prepared coal sample of traditional moulded coal mould is easily subject to damage when the demoulding, and by pressured column outer sleeve and shaping mould inner sleeve with the use of, can suitably prepare various sizes of coal sample, can effectively save experimental cost.And owing to transport can be split, it has been significantly reduced transport difficulty.Present configuration is simple, and with low cost, using effect is good.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention
Embodiments of the invention: can improve the moulded coal mould of coal sample ratio defective product, including pressured column 1, shaping mould 2, shaping mould 2 is split-type structure, and shaping mould 2 is formed a bottom lock, the cylindrical structure of open top by 2-3 circular arc assembly；Being additionally provided with collar 4, the internal diameter of collar 4 is corresponding with the external diameter of shaping mould 2, respectively sets a collar 4 on the top of shaping mould 2 and bottom, for threadeding between shaping mould 2 with collar 4；Being externally provided with pressured column outer sleeve 5 at pressured column 1, be provided with shaping mould inner sleeve 3 in shaping mould 2, the external diameter of shaping mould inner sleeve 3 is corresponding with the internal diameter of shaping mould 2, and inner sleeve 3 is cylindrical structure and its open at both ends of split-type；The internal diameter of pressured column outer sleeve is corresponding with pressured column external diameter；Described pressured column outer sleeve 5 and shaping mould inner sleeve 3 are more than one group, and often group pressured column outer sleeve is collocated with each other, according to ascending descending with the size respectively shaping mould inner sleeve of size, the coal sample made for obtaining different size specification；Being provided with limiting card 6 on the inner chamber top of shaping mould 2, the outer wall at shaping mould inner sleeve 3 is provided with stopper slot 7, and stopper slot 7 is corresponding with limiting card 6 position.
In use, select suitable pressured column outer sleeve 5 and shaping mould inner sleeve 3 according to required size, after shaping mould 2 and shaping mould inner sleeve 3 are installed, fix with collar 4, and be placed on experiment porch, pressured column 1 and pressurization outer sleeve 5 are fixed on pressurization instrument.Then adding raw material, the coal dust after processing according to desired density adds in the shaping mould 2 after assembling.Start pressurized equipment, by pressured column 1, the coal dust in mould is pressurizeed, be allowed to real molding of pounding.After extrusion forming process terminates, mold removal from experiment porch, remove collar 4, split into pattern 2 and shaping mould inner sleeve 3, and take out coal sample.
