Abstract
The utility model provides a casting mold structure for a grid of a storage battery polar plate. The casting mold structure comprises two hanging lugs, a grid mold group composed of a plurality of grid molds and at least one lead guiding port, wherein the two hanging lugs are respectively arranged at the two sides of the grid mold group, each grid mold is fixedly connected with the adjacent hanging lug by a pole lug, the lead guiding port is positioned above the grid mold group, a buffering strip is arranged between the lead guiding port and the grid mold group, a garbage strip is arranged between the cushion strip and the grid mold group, and garbage strip is also arranged at the bottom end of the grid mold group. The casting mold structure has the advantages that as the two garbage strips are additionally arranged, blind edges can be formed inside the garbage strips, and the garbage strips of a casted grid can be removed by cutting, thereby obtaining the grid without the blind edges and greatly improving the product quality.
Description
[technical field]
The utility model relates to a kind of casting die structure of battery industry, relates in particular to a kind of casting die structure of electric boosted automobile-used accumulator grid.
[background technology]
In order to reduce the primary pollution source fuel-engined vehicle waste gas of urban atmosphere; And alleviate that the world oil reserves reduce gradually and the energy crisis that causes; Electric motor car and hybrid electric vehicle arise at the historic moment as a kind of vehicles of intelligence; And worldwide progressively be formed with the industry of bright prospects, and become the principal element of restriction electric motor car development as the vehicle power of electric motor car core.On-vehicle battery is the heart of electric motor car, the competition of exploitation electric motor car, the competition that the most important thing is to develop vehicle-mounted electrical source of power.As the vehicle power of electric motor car and hybrid electric vehicle, compare other electrochmical power source, lead accumulator is still the first-selection in nearly ten years.Along with the development and the progress of Lead Acid Battery Industry, this century, the seventies began to have occurred lead accumulator gas chemical combination Sealing Technology again.The development of the clear lead-acid accumulator of this technique table has got into the new historical stage.Grid is one of base substance of lead accumulator, and it accounts for the 20%-30% of battery gross mass, and grid mainly contains two big functions: support active material, serve as the carrier of active material; The conduction and compile electric current, electric current is evenly distributed on the active material.It both provided mechanical support to cell active materials, was again the main channel that electric current flows, so its " spine " of pole plate still not, pole plate " blood circulation " system especially, and it is the critical component of high-capacity lead-acid storage battery.
At present; The casting die structure of existing accumulator grid generally includes the grid set of molds that is made up of a plurality of grid moulds; Two hangers, at least one lead mouth of leading; Two hangers lay respectively at the both sides of grid set of molds, and whenever this grid mould is fixedly connected with adjacent hangers through a lug, and lead the top that plumbous mouth is positioned at the grid set of molds.The grid casting is first procedure during pole plate is produced, and the quality of quality is very big to the quality influence of pole plate.Existing grid is to form through the mold casting; In the casting; After releasing agent spraying finishes, the plumbous liquid of uniform temperature is quantitatively injected in the mold from plumbous spoon, plumbous liquid grid housing die size in mold is actual required size; Yet the housing of the grid highest and lowest that casts out has blind limit once in a while, has a strong impact on the quality of pole plate.
[utility model content]
The utility model technical problem to be solved is to provide the casting die structure of the accumulator grid that a kind of blind limit forms in the rubbish bar.
The utility model solves the problems of the technologies described above through following technical scheme: a kind of casting die structure of accumulator grid; Comprise the grid set of molds that two hangers, are made up of a plurality of grid moulds; At least one lead mouth of leading; Said two hangers lay respectively at the both sides of grid set of molds, and whenever this grid mould is fixedly connected with adjacent hangers through a lug, saidly lead the top that lead mouthful is positioned at said grid set of molds; Said leading between plumbous mouth and the grid set of molds is provided with a buffer bar, and between said buffer bar and the grid set of molds and the bottom of grid set of molds is respectively arranged with a rubbish bar.
The cross sectional shape of the rubbish bar between said buffer bar and the grid set of molds is a rectangle; The cross sectional shape of the main part of the said rubbish bar that is positioned at grid set of molds bottom is a rectangle, and a lateral edges of this main part stretches out and forms at least 2 support components.
The width of said rubbish bar main part in grid set of molds bottom and thickness is big than rubbish bar between said buffer bar and grid set of molds all.
The advantage of the utility model is: between said buffer bar and grid set of molds and the bottom of grid set of molds set up a rubbish bar respectively; Blind limit is formed in the rubbish bar; The grid that is cast out is removed the rubbish bar through cutting, thereby forms the grid on no blind limit.
[description of drawings]
Fig. 1 is the casting die structure sketch map of the utility model accumulator grid.
[specific embodiment]
With reference to shown in Figure 1; A kind of casting die structure of accumulator grid; Comprise grid set of molds 2 that two hangers 1, are made up of a plurality of grid moulds 22, at least onely lead plumbous mouthful 3, said two hangers 1 lay respectively at the both sides of grid set of molds 2, and each grid mould 22 is fixedly connected with adjacent hangers 1 through a lug 4; Saidly lead plumbous mouthful 3 top that is positioned at said grid set of molds 2, said leading between plumbous mouthful 3 and the grid set of molds 2 is provided with a buffer bar 5.The utility model is general in casting cycle to spray mold to play heat insulation effect with releasing agent in advance, and being provided with of buffer bar can slow down the impulsive force that plumbous liquid gets into mold, prolongs the service time of releasing agent.
The utility model also comprises rubbish bar 6 and rubbish bar 7, and said rubbish bar 6 is located between said buffer bar 5 and the grid set of molds 2, and said rubbish bar 7 is positioned at the bottom of grid set of molds 2.For making manufacturing process simple, will be made as rectangle at the cross sectional shape of the rubbish bar 6 between said buffer bar 5 and the grid set of molds 2, it is preferably dimensioned to be width: 1.80mm, thickness: 1.50mm, length: 290.00mm.The cross sectional shape of agent structure that is positioned at the rubbish bar 7 of grid set of molds 2 bottoms is a rectangle; It is preferably dimensioned to be width: 2.15mm; Thickness: 5.00mm, length: 290.00mm, wherein a lateral edges of the main part of rubbish bar 7 stretches out and forms at least 2 support components 8; Present embodiment adopts 3 support components 8, and this support component 8 mainly plays a supportive role.The width of said rubbish bar 7 and thickness all width and the thickness than said rubbish bar 6 are big, and this is because the width of rubbish bar 7 large-sizes and thickness can let plumbous liquid converge in the mold bottom to be amassed, even rubbish bar 7 is shaped bad or defectiveness has finally also cut.The utility model because extra has increased by two rubbish bars, and blind limit is formed in the rubbish bar, and the grid that is cast out is removed the rubbish bar through cutting, thereby obtains not having the grid on blind limit, and the blind limit of grid housing quality problems are significantly reduced, and has greatly improved product quality.
