Description
Technical field
The utility model relates to the manufacturing technology of lead-acid accumulator, particularly relates to a kind of casting mould of lead acid accumulator plate grid.
Background technology
Lead-acid accumulator is a kind of electrochmical power source, is electric energy by converts chemical energy, belongs to reversible dc power supply, close to the inner portion chemical reaction store electrical energy or power to electrical equipment.Lead-acid accumulator is made up of pole plate, dividing plate, electrolyte, battery case etc.Pole plate is the core of lead-acid accumulator, the chemical reaction of battery charge and discharge mainly relies on the active material on pole plate and electrolyte to carry out, pole plate is divided into positive plate and negative plate, and positive plate and negative plate are all made up of grid and the active material be coated on grid.
Wherein, the effect of grid rises and supports active material and conduction, has necessarily good electric conductivity, corrosion resistance and certain mechanical strength, and the quality of its quality directly will affect the electric conductivity of battery that lead plaster divides adhesive ability and assembles.
At present, in grid is manufactured, in order to improve the casting quality of grid, the cavity of surplus can be set in the bottom of die cavity, make lead water be full of grinding tool.The plate grid die of prior art comprises the fixed half and moving half cooperatively interacted, fixed mould structure as shown in Figure 1, comprise body 12, body 12 is provided with pouring basin, pouring basin comprises the die cavity corresponding with the shape of grid, be positioned at die cavity both sides and the hangers chamber be communicated with die cavity both sides, and to be positioned at below die cavity and with the clout chamber 15 be communicated with below die cavity, the side of body 12 also offers and is poured into feeding mouth in die cavity and hangers chamber for extraneous plumbous liquid, in casting cycle, lead water enters die cavity and hangers chamber from feeding mouth, then clout chamber 15 is flowed into from die cavity, thus make plumbous liquid can fully be full of whole die cavity.
Said structure is owing to being provided with clout chamber, in process of production, a large amount of leftover bits will be produced, metal secondary returning found alloying element scaling loss and a large amount of lead skim produce, in the face of industry keen competition environment day by day, the energy-saving and cost-reducing focus having become each enterprise, therefore must reduce waste material as much as possible and produce.
Utility model content
The utility model provides a kind of casting mould of lead acid accumulator plate grid, while guarantee grid quality, decreases the generation of leftover pieces, at reduction production cost simultaneously, can play energy-saving and cost-reducing effect.
A kind of casting mould of lead acid accumulator plate grid, comprise fixed half and moving half, described cover half comprises body, described body is provided with the casting groove comprising multiple grid die cavity, described casting groove both sides are provided with the passage being communicated with adjacent panels grid-type chamber, also be provided with the hangers die cavity be communicated with it outside described passage, described cover half be also provided with the exhaust duct that several are communicated with described passage or described hangers die cavity.
By at the exhaust duct be communicated with passage or hangers die cavity, thus after plumbous liquid enters casting groove, be convenient in chamber or plumbous liquid inside gas discharge, without the need to arranging clout chamber at casting trench bottom again, plumbous liquid just can be paved with whole casting groove fast, thus reduces the quantity of burr in casting process, reduces leftover bits, reduce production cost simultaneously, play energy-saving and cost-reducing effect.
In order to make the gas in casting groove discharge fast, preferably, the exhaust duct be communicated with hangers die cavity is rectangular in shape.The laterally projecting setting of hangers die cavity, by the exhaust duct shape at a right angle be communicated with it, can discharge gas fast.
In order to make the exhaust duct Quick air-discharge with described channel connection, preferably, tilt towards feed liquor direction from inside to outside with the exhaust duct of described channel connection.According to the principle that hot gas rises, exhaust duct is obliquely convenient to discharge hot gas.
If but angle of inclination is excessive, can extend the length of exhaust passage, therefore, preferably, be 25 degree ~ 35 degree with the angle of inclination of the exhaust duct of described channel connection.
In order to prevent plumbous liquid from forming overlap burr in exhaust duct position, preferably, the degree of depth of described exhaust duct is 0.03 ~ 0.07mm.Only have the air in casting groove to pass through during casting, plumbous liquid itself also has some tension, as long as exhaust duct is very little, plumbous liquid can not produce overlap burr at this.
In order to make plumbous liquid can flow into casting groove smoothly, preferably, described dynamic model is provided with 5 ~ 6 through exhaust bars.
Preferred further, leave the compressed air inlet port communicated with each exhaust bar immediately below described dynamic model.
The beneficial effects of the utility model:
The casting mould of lead acid accumulator plate grid of the present utility model, by at the exhaust duct be communicated with passage or hangers die cavity, thus after plumbous liquid enters casting groove, be convenient in chamber or plumbous liquid inside gas discharge, without the need to again casting trench bottom clout chamber is set, plumbous liquid just can be paved with whole casting groove fast, thus the quantity of burr in minimizing casting process, reduce leftover bits, reduce production cost simultaneously, play energy-saving and cost-reducing effect.
