Abstract
The invention discloses a battery cast-weld mould. The battery cast-weld mould comprises a cast-weld mould body, wherein the inside of the cast-weld mould body is provided with a cavity, the bottom of the cast-weld mould body is provided with a base plate, the base plate and the cast-weld mould body are connected together through an annular sealing structure, and the outer annular surface of the annular sealing structure is provided with an annular sealing. Only the heat stress of the mould is exerted on the annular sealing in longitudinal direction, but the heat stress is far less than the heat stress generated by the mould in horizontal direction when the mould expands with heat or contracts with cold, thus reducing the fatigue at the sealing and increasing the service life of the entire mould. Meanwhile, the positioning mechanism of the mould is modified in the invention and an elastic buffer structure is added so that when the mould expands with heat or contracts with cold, the great pull acting on the mould, caused by the positioning device used for fixing the mould is relieved to the maximum and the fatigue of the mould material is reduced.
Description
Technical field
The present invention relates to a kind of cast welded mold, is a kind of cast welded mold that the lead-acid accumulator afflux is lined up type that is used for specifically.
Background technology
The mode of the connection process using of polar plate of lead acid storage battery welding in the prior art, but a plurality of cells that work independently are arranged in internal storage battery, these cell structures are identical, all comprised positive plate and negative plate, the factor amount is more, adopts the words of artificial welding, required labour is big, production efficiency is very low, but final product quality is not high, therefore needs a kind of special cast welded mold to carry out welding job.
Present cast welded mold structure is: cast-weldmould body and function metal is made, in the die body is cavity, the die body both sides have the aqueous vapor passway of turnover respectively, the die body upper surface has battery current collecting to line up the concave path groove and the pole groove of type, the die body bottom is welded in the madial wall of die body cavity with the small size metal base plate, four positioner expansions place below the mould body lumen wall of cast-weldmould form with the mode of block of metal piece boring.There is following shortcoming in this structure: the lateral stress of mould changes greatly, and metal base plate and mould body lumen wall weld bear nearly all thermal stress that produces under expanding with heat and contract with cold, and the easy fatigue of weld disconnects very much, and die life reduces; Four positioners are to form with the mode that block of metal is holed, the thermal stress that is produced after mould expands with heat and contract with cold all concentrates on four fixing locating holes, because of the effect of power is mutual, weld bore all thermal stress at the bottom of this had just increased mould once more, the fatigue of critical increase weld, the service life of shortening mould.The patent No. is to disclose a kind of battery current collecting row cast-weldmould in the patent of " 200720009354.8 ", and its structure is exactly typical example in the prior art, assembles the shortcoming loaded down with trivial details, that cooling effectiveness is low though solved, and the service life of mould is not high.
Summary of the invention
Problem to be solved by this invention is exactly the shortcoming at prior art, a kind of battery cast welded mold is provided, under the prerequisite that keeps original afflux molding structure, change the connected mode and the structure of cast-weldmould body and base plate, and simultaneously positioner is improved, greatly improve the service life of cast welded mold.
For achieving the above object, the present invention adopts following technical scheme: a kind of battery cast welded mold, comprise the cast-weldmould body, be provided with cavity in the cast-weldmould body, cast-weldmould body bottom is provided with base plate, it is characterized in that: connect as one by annular enclosed structure between base plate and cast-weldmould body, be provided with loop seal along the outer ring surface of annular enclosed structure, along the protruding eaves that bottom edge is circular layout and raises up, protruding eaves is pegged graft to cooperate with cavity chamber wall and is formed described annular enclosed structure.The mould that loop seal is subjected to thermal stress in a longitudinal direction is significantly smaller than the thermal stress that is produced in the horizontal direction when mould expands with heat and contract with cold, and reduces the fatigue of sealing part, improves the service life of entire die with this.
Further, protruding eaves upper surface is provided with groove, and cavity chamber wall is plugged in the groove.Groove and cavity chamber wall are pegged graft and can not only be improved the bulk strength of mould, have also born a part of thermal stress that mould expands with heat and contract with cold and produced to a certain extent, have protected the ring-type enclosuring structure.
Further, be provided with the v-notch of indent on the outer ring surface of annular enclosed structure, described loop seal is arranged on the v-notch bottom.
Further, the base plate two ends are provided with positioner, comprise locating piece and are located at the interior elastic buffer structure of locating piece.Elastic buffer structure makes positioner have a buffering course when being subjected to tensile force, under mould expands with heat and contract with cold state, alleviate because of the device that is positioned fixedly causes great pulling force to greatest extent, alleviate the fatigue of mold materials, also increased the service life of mould.
Further, described elastic buffer structure is a S shape groove of inwardly offering from the locating piece lateral surface.
Further, be distributed with some horizontal gussets and vertical gusset on the pocket base wall of cast-weldmould body, purpose alleviates the distortion of cast-weldmould body surface under the state of expanding with heat and contract with cold in order to improve the intensity of cast-weldmould body.
Further, also be provided with the muscle post on the pocket base wall of cast-weldmould body, the fixedly through hole of muscle post is set on the base plate, purpose also is in order further to improve the intensity of cast-weldmould body.
Advantage of the present invention: under the prerequisite that keeps the original afflux molding structure of mould, change the connected mode and the structure of cast-weldmould body and base plate, by be provided with annular enclosed structure and be parallel to the loop seal realization cast-weldmould body of base plate and being connected of base plate, the tensile force of sealing part reduces, and die life improves; Also the detent mechanism of mould is improved simultaneously, increased elastic buffer structure, make mould under the state of expanding with heat and contract with cold, alleviate because of the device that is positioned fixedly causes great pulling force to greatest extent, alleviate the fatigue of mold materials; In addition, also further increase gusset and muscle rod structure and improved mold integral intensity, prolonged the service life of battery cast welded mold of the present invention greatly, reduced the mold repair cost.
