Abstract
The invention discloses a mould for casting a post lead part of a lead-acid storage battery, comprising an inactive mould, an active mould and a pouring plate, wherein the binding site of the inactive mould and the active mould is provided with a post lead part casting cavity, the improvement of the mould comprises that a platform is arranged at the bottom of the inactive mould, a groove dead against the casting cavity is arranged at the top of the platform, the groove is an oblong one, one end of the groove facing to the inactive mould is matched with a copper core in a lead part, and a gap is kept between one end of the groove facing to the active mould and the copper core. The mould is used for casting the output post of the lead-acid storage battery, and automatic demoulding can be realized, thus the labour intensity is reduced, the production efficiency is improved, and an obvious progress is made compared with the manual demoulding operation in the traditional mould casting process.
Description
Technical field
The present invention relates to the equipment that uses in lead accumulator production, relate in particular to a kind of mould for casting post lead part of lead-acid storage battery.
Background technology
Lead-acid accumulator output pole is one of indispensable assembly, in the lead accumulator production process, it is the plumbous part of pole that goes out to be shaped by die casting that one procedure is arranged, again other assembly of the plumbous part of pole and lead accumulator, as positive/negative plate, glass fibre separator, battery case etc., be assembled into a complete battery at utmost point group assembly process by welding manner.The plumbous design of part of pole generally is comprised of clad copper core in the lead base body, and the resistance of copper metal is little, hardness is high, wear-resisting, therefore can be processed into female thread structure, easily is connected by screw rod with the connecting line of extraneous load.The effect of the plumbous part of pole is collect the electric current that on the inside battery pole plate, chemical reaction produces and output to external loading in discharge process, in charging process, foreign current is imported internal storage battery, plays the input and output function of current.
The casting of the plumbous part of common pole is adopted by dynamic model, cover half, is watered the mould that flitch combines, and copper core bottom is same plane with moving, cover half bottom.Put into the copper core in the bottom before casting, close dynamic model and cover half cover and water flitch, pour appropriate molten lead liquid from watering the flitch porch into toward mould in, until plumbous liquid complete cooling after, push open and water flitch, then drive dynamic model and make it to separate with cover half along the cooperation planar movement.In this process, because the plumbous part of pole is larger with the dynamic model contact-making surface, leave cover half with dynamic model, at last need to be by manually pole lead part and dynamic model being broken away from and take out.
Adopt above-mentioned die casting, bottom the plumbous part of pole, a plurality of double wedges are arranged, structure is more complicated, surface area is large, and double wedge part simultaneously due to the softer characteristic of plumbous hardness, causes the plumbous part of pole to be attached on dynamic model all on dynamic model, need as previously mentioned by manual type, the plumbous part of pole and dynamic model to be broken away from, so not only cause and lose time, production efficiency is low, and when a plumbous part of a plurality of poles of mould top casting, dynamic model weight is heavier, causes the labour intensity of stripping operation larger.Therefore the demoulding of the plumbous part of pole becomes the key factor that labour intensity is large, production efficiency is low.
In order to solve the plumbous part release problems of pole, the method that adopts releasing agent is also arranged, but in actual production process, adopt the mold temperature of spraying releasing agent need to reach 180 ℃ of left and right, releasing agent ability good bond is on mould, in the situation that mold temperature is higher, manual operability is relatively poor, so this mode is not used widely in battery production.
Summary of the invention
The object of the invention is to overcome existing weak point of watering mold, provide a kind of and can realize automatic demoulding, the mould for casting post lead part of lead-acid storage battery that reduces labour intensity, enhances productivity.
Technical scheme of the present invention is: mould for casting post lead part of lead-acid storage battery, consisted of by the cover half that is oppositely arranged, dynamic model and the flitch that waters that is placed in cover half, dynamic model top, cover half, dynamic model opposite face binding site are provided with the plumbous part mold cavity of pole, its improvements are that described cover half bottom is provided with the platform that stretches to dynamic model one side, this table top is provided with the groove of copper core in the plumbous part of the described pole of placing of above-mentioned mold cavity, and depth of groove is less than described copper core extension height.
Further scheme is: described groove is oval-shaped slot, and its long axis direction is consistent with dynamic model die sinking direction, and oval-shaped slot matches towards an end and the described copper core of cover half, and oval-shaped slot is gapped towards an end and the described copper core of dynamic model.
Adopt the plumbous part of die casting provided by the invention, during die sinking, pull open dynamic model by external force, plumbous part moves with dynamic model, at first separate with cover half, but in very fast plumbous part, the copper core is limited by oval-shaped slot, motion is obstructed, and separates with dynamic model immediately, and then takes out workpiece.So no longer need human assistance, can realize automatic demoulding, reduce labour intensity, enhance productivity.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is knockout course schematic diagram of the present invention;
Fig. 3 is the existing casting die structure schematic diagram that waters.
The specific embodiment
Referring to accompanying drawing, the present invention is by cover half 3, dynamic model 2 and water flitch 4 and consist of, moving, cover half opposite face binding site is provided with the mold cavity of the plumbous part 5 of pole, the cover half bottom is provided with platform 6, table top is provided with the oval-shaped slot 7 over against mold cavity, in the plumbous part of one end of groove and pole, copper core 1 matches, and the other end and copper core are gapped.
Before casting, first copper core 1 is placed in advance an end place of the oval-shaped slot 7 of cover half 3, the dynamic model 2 and water flitch 4 of then closing, then pour into the plumbous liquid of appropriate motlten metal.after plumbous liquid is fully cooling, take away and water flitch, pull dynamic model 2 to make it to separate with cover half 3 by external force, the plumbous part 5 of pole can be attached on dynamic model 2 and separate with cover half 3 together, after plumbous part 5 mass motion one segment distances of pole, copper core 1 contacts with the other end of oval-shaped slot 7, oval-shaped slot 7 has stopped the continuation campaign of the plumbous part 5 of pole, produce a reaction force, can make copper core 1 stop motion of the plumbous part 5 of pole, cause the plumbous part 5 of pole also finally to separate with the generation from the bottom up between dynamic model 2 is loosening, in the process that dynamic model 2 continues to pull open, the plumbous part 5 of pole gets off with regard to Automatic-falling.
Existingly water (shown in Figure 3) in mold, the bottom of cover half 8, dynamic model 9 and plumbous part bottom are at same plane, and during die sinking, plumbous part moves with dynamic model, can't Automatic-falling.
