Abstract
The utility model relates to the accurate link structure of large mold, comprise front die holder, rear die holder, centering block, set bolt, pressing plate, connecting bolt, contiguous block, clamping screw, in using, centering block is fixed on front die holder by pressing plate, connecting bolt is utilized to fix, then two contiguous blocks are separately fixed at front die holder, on rear die holder, after front and back die holder is alignd, by clamping screw through two contiguous blocks, while locking, due to front die holder, rear die holder is provided with the corresponding groove with centering block with centering block correspondence position, therefore, front die holder, rear die holder can while locking, automatically centering is carried out.In order to make centering between front die holder, rear die holder more smooth, difference in size is less, in the both sides of front die holder, rear die holder, can use the accurate link structure of large mold described in the utility model respectively.
Description
Technical field
The utility model relates to mechanical manufacturing field, specifically the accurate link structure of large mold.
Background technology
Making blank become under external force has the instrument of the product of given shape and size to be called mould, it be in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product, be widely used in stamping-out, shaping and punching, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the formed machining of injection moulding.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and cover half (or punch and die) two parts, the two partable.Load blank time separately or take out product, when closing up, making product be separated with blank or be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy, and the development level that mould is produced is one of important symbol of machine-building level.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts.It realizes the processing of article profile mainly through the change of institute's moulding material physical state.
When our Design and manufacture large mold, (usual die boundary dimensions length is more than 3000mm, or weight just includes large-scale scope in more than 10 tons), consider whether the range of work of our process equipment can process part large-scale like this, whether the maximum hoisting weight of crane gear can this large mold of slinging of safety, when workbench beyond process equipment of the profile of part, or during the maximum hoisting weight of the weight of mould beyond crane gear, we can be divided into two (or more) parts to the lifting scope of the range of work and crane gear that meet process equipment heavy parts, then two assembling parts are got up, although be divided into the restriction that two parts can solve the safe hoisting weight of the equipment range of work and crane gear, but mould is accurate technological equipment, two assemblies how could be accurate be assembled into an entirety? the long assembly relative positional accuracy of two 1500mm how could be allowed to control within 0.05mm, also do not have a kind of structure simple at present, easy to use, the fastening accurate link structure that can realize centering can be easily passed through.
Utility model content
The utility model, just for above technical problem, provides a kind of structure simple, easy to use, can easily pass through the fastening accurate link structure that can realize centering.
The utility model is achieved through the following technical solutions:
The accurate link structure of large mold, comprise front die holder, rear die holder, centering block, set bolt, pressing plate, connecting bolt, contiguous block, clamping screw, it is characterized in that front die holder, centering block is provided with between rear die holder, front die holder, rear die holder is provided with groove with centering block correspondence position, linked together by pressing plate between centering block and front die holder, centering block and pressing plate, front die holder is connected by connecting bolt with between pressing plate, front die holder, rear die holder is connected with symmetrical contiguous block respectively by set bolt outside junction, connected by clamping screw between symmetrical contiguous block.Contiguous block is L-shaped.Set bolt on contiguous block is at least two.Contiguous block on contiguous block on front die holder and rear die holder still has a segment distance after locking.
In using, centering block is fixed on front die holder by pressing plate, utilize connecting bolt to fix, then two contiguous blocks are separately fixed on front die holder, rear die holder, after front and back die holder is alignd, by clamping screw through two contiguous blocks, while locking, due to front die holder, rear die holder being provided with the corresponding groove with centering block with centering block correspondence position, therefore, front die holder, rear die holder while locking, can carry out centering automatically.In order to make centering between front die holder, rear die holder more smooth, difference in size is less, in the both sides of front die holder, rear die holder, can use the accurate link structure of large mold described in the utility model respectively.
The utility model structure is simple, easy to use.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
1-front die holder, 2-rear die holder, 3-centering block, 4-set bolt, 5-pressing plate, 6-connecting bolt, 7-contiguous block, 8-clamping screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The accurate link structure of large mold, comprise front die holder 1, rear die holder 2, centering block 3, set bolt 4, pressing plate 5, connecting bolt 6, contiguous block 7, clamping screw 8, it is characterized in that front die holder 1, centering block 3 is provided with between rear die holder 2, front die holder 1, rear die holder 2 is provided with groove with centering block 3 correspondence position, linked together by pressing plate 5 between centering block 3 and front die holder 1, centering block 3 and pressing plate 5, front die holder 1 is connected by connecting bolt 6 with between pressing plate 5, front die holder 1, rear die holder 2 is connected with symmetrical contiguous block 7 respectively by set bolt 4 outside junction, connected by clamping screw 8 between symmetrical contiguous block 7.Contiguous block 7 is L-shaped.Set bolt 4 on contiguous block 7 is at least two.Contiguous block 7 on front die holder 1 still has a segment distance with the contiguous block 7 on rear die holder 2 after locking.
In using, centering block 3 is fixed on front die holder 1 by pressing plate 5, utilize connecting bolt 6 to fix, then two contiguous blocks 7 are separately fixed on front die holder 1, rear die holder 2, after front and back die holder 2 is alignd, by clamping screw 8 through two contiguous blocks 7, while locking, due to front die holder 1, rear die holder 2 being provided with the corresponding groove with centering block 3 with centering block 3 correspondence position, therefore, front die holder 1, rear die holder 2 while locking, can carry out centering automatically.In order to make centering between front die holder 1, rear die holder 2 more smooth, difference in size is less, in the both sides of front die holder 1, rear die holder 2, can use the accurate link structure of large mold described in the utility model respectively.
The utility model structure is simple, easy to use.
