Description
Technical field
The utility model relates to a kind of technical field of mold, particularly relates to a kind of hole flanging compound die.
Background technology
Compound die refers to that punch press is in one stroke, completes a kind of mould structure of multiple operation such as blanking, punching.Production lot compound die can be enhanced productivity exponentially, and production lot is larger, enhances productivity and more seems important.Stamped workpieces precision when the dimensional accuracy of stamped workpieces or the position accuracy demand such as axiality, symmetry higher time, should consider to adopt compound die.The compound working procedure quantity of the general compound die of quantity of compound working procedure is below four operations, and more operation will cause mould structure too complicated, and simultaneously the intensity of mould, rigidity, reliability also will decline thereupon, manufacture and maintenance more difficult.Varying in size of the size compound die of mould structure, its structure adopted and plate have complicated and simple difference, and stripper is also different.
Compound die is the modelling stone being overlaped by external mold and internal mold and formed.After the biological remains (valve as Bivalve) be kept in deposit are dissoluted, if deposit not consolidation and still there is plasticity around, due to burden pressure make remains corrosion after the upper and lower compacting of institute's spacing and closing, therefore external mold and internal mold stack together, and form each compound die all having table impression (as flesh trace) in shell appearance impression (as shell decorations) and shell of upper and lower two half blocks.Common in Bivalve, Brachiopods have compound die.Blank is made to become the instrument of the product having given shape and size under external force.Be widely used in stamping-out, 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.Take out product time separately, make blank inject mold cavity when closing up and 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.
Mould is except itself, and also need die holder, mould bases, guider and product liftout attachment etc., these parts are generally all made universal.Mould Enterprise needs to do to do essence greatly, will according to the market demand, and the condition such as technology, fund, equipment, determine product orientation and market orientation, these ways are especially worth small mould Enterprise Learning and reference, concentrate strength on the technical advantage and the product advantage that progressively form oneself.So China's Mould Enterprise actively must make great efforts the experience of these advanced enterprises of foreign, so that its following better development.Modify, if use mechanical type leveling saw to amputate the gripper edge of plastic, in the height direction, at least will have the surplus of 6 ~ 8mm.Other finishing process, as grinding, laser cutting or jet, also must leave surplus.Gap between knife edge due line of cut is minimum, and dispersion of distribution during perforating die finishing is also very little, and these all will be noted.Shrink and distortion, plastics easily shrink (as PE), and some plastic is yielding, in any case prevention, plastic all can deform at cooling stage.Under these conditions, the profile of mould will be changed over to adapt to the geometrical deviation of plastic.Such as: although plastic wall keeps straight, its reference center departs from 10mm; Mold base can be raised, to adjust the amount of contraction of this distortion.Amount of contraction, must consider following shrinkage factor when manufacturing plastics sucking moulding mould.Moulded products shrinks.If the shrinkage factor of plastics can not be known clearly, then must sample or be obtained by test with the mould of similar shape.Attention: can only obtain shrinkage factor by this method, can not obtain being out of shape size.The contraction that the adverse effect of intermediate medium causes, as pottery, silicon rubber etc.The contraction of mould material therefor, as contraction during cast aluminum-molykote composite material.
Current existing mold parts processing and manufacturing is more difficult, and cost is higher, and punch-die is easily subject to the restriction of minimum wall thickness (MINI W.), and the less lower part of pitch of holes in some, endoporus and Distances Between Neighboring Edge Points should not be adopted, simultaneously when discharging, because workpiece produces flexural deformation, be not easy pickup.
