Description
Technical field
The present invention relates to mould applications, specifically a kind of gear die.
Background technology
Mould, makes blank become the instrument of the product having given shape and size under external force.
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, bear the expansive force of blank, structural strength, rigidity, case hardness, surface roughness and machining accuracy are all had higher requirements, the development level that mould is produced is one of important symbol of machine-building level, mould kind is a lot, can be divided into: the 1. mould of processing metal according to processing object and processing technology.Comprise stamping die (as blanking die, bending die, Drawing Die, plunging die, shrinkage cavity mould, forcer, bulging die, sizing die etc.), forging die (as die forging mould, upsetting die etc.) and extrusion die and compression mod etc.2. the mould of machining of non-metallic and powder metallurgy.Comprise Mold for Plastics (as injection mould, compression mould and extrusion molding mould etc.), rubber pattern and powder metallurgy mould etc.According to design feature, mould can be divided into again the blanking die of plane and have the swaging die in space.Mould is generally single-piece, small serial production.Mould is except itself, and also need die holder, mould bases, guider and product liftout attachment etc., these parts are generally all made universal.Tool is the large class instrument of a carpenter, ironworker, pincers worker, machinery, automatically controlled and some other artifacts, mainly as a kind of instrument of assisting control position or action (or both).Because TaiWan, China was once ruled for a long time by Japan, also just get used to " tool " this word.
Tool is just widely used before the industrial age, comprises mechanical tool, carpenter's tool, welding fixture, jewelry tool and other field.The tool of some type is also referred to as " mould " or " accessory ", and its main purpose is repeatability and the recasting repeating certain part accurately.An obvious example is when copy key, and original key is fixed on tool usually, and machine like this just can copy by the guiding of original key outward appearance the key made new advances.
Press the difference of shaping material, mould can be divided into metal die and nonmetal mould.
Metal die is divided into again: casting mould (non-ferrous metal die casting, steel casting), diel and forging mold etc.; Nonmetal mould is also divided into: mould of plastics and inorganic non-metallic mould.And according to the difference of the material of mould own, mould can be divided into: sand mold mould, metal die, vacuum mold, paraffin mould etc.Wherein, along with the fast development of high molecule plastic, the life of mould of plastics and people is closely related.Mould of plastics generally can be divided into: injecting molding die, extrusion moulding mould, gas-assisted forming mold etc.Non-panel beating steel part--cold-heading, die forging, the metal pattern etc. of large-scale production.Panel beating discharging--hot rolling, cold rolling, hot rolling, cold coiling panel beating--drawing, integer, bending, punching, blanking non-ferrous metal--die casting, powder metallurgy working of plastics--injection moulding, blowing (plastic bottle), other classification of extrusion molding (pipe fitting) mould: alloy mold, sheet metal mould, mould of plastics, diel, rubber mold, casting mould, forging mold, extrusion die, die casting, automobile die, mould of thread.
Having many tools why to produce to be because the needs of business, because there is eurypalynous tool to be perhaps customize, is to increase productivity, repeating specific action or make work more accurate mostly.Similar tool may because of being used in different when and wheres.
Produce a product in batches, design and manufacture a kind of suitable mould for enhancing productivity, saving production cost significant.Also there is no a kind of particular manufacturing craft being specifically designed to production helical gear at present.
Summary of the invention
The present invention is above technical problem just, provides a kind of and is specifically designed to the particular manufacturing craft producing helical gear.
The present invention is achieved through the following technical solutions:
A kind of gear die, comprise rush-up seat, upper punch pad, shaping upper punch, upper punch lid, mould in shaping, shaping undershoot, undershoot pad, undershoot lid, lower red seat, shaping following two punch, following two punch pad, following two punch lid, following two punch seat, shaping plug, plug lid, mandrel holder, it is characterized in that shaping upper punch is pressed on rush-up seat by upper punch lid, upper punch pad is provided with between shaping upper punch and rush-up seat, in shaping, mould hollow space ecto-entad is followed successively by shaping undershoot, shaping following two punch, shaping plug, shaping undershoot is pressed on lower red seat by undershoot lid, undershoot pad is provided with between shaping undershoot and lower red seat, shaping following two punch is pressed on following two punch seat by following two punch lid, following two punch pad is provided with between shaping following two punch and following two punch seat, shaping plug is fixed on mandrel holder by plug lid.In shaping, corresponding skewed slot is arranged at mold cavity top, shaping upper punch bottom.Upper punch pad, undershoot pad, following two punch pad are provided with helicla flute.
Accompanying drawing explanation
Accompanying drawing Fig. 1 is structural representation of the present invention, wherein:
1-rush-up seat, 2-upper punch pad, 3-shaping upper punch, 4-upper punch lid, mould in 5-shaping, 6-shaping undershoot, 7-undershoot pad, 8-undershoot lid, 9-lower red seat, 10-shaping following two punch, 11-following two punch pad, 12-following two punch lid, 13-following two punch seat, 14-shaping plug, 15-plug lid, 16-mandrel holder.
