Abstract
A plate grid die for restraining the generation of valve-control storage battery plate grid pores is used for solving the problem of the generation of the valve-control storage battery plate grid pores. The technical scheme is as follows: the plate grid die is provided with a casting basin which is matched with a plate grid in shape; a row of casting gates are arranged at the upper part of the casting basin; after improvement, plate lug parts positioned at two sides of the casting basin are respectively provided with four air paths, wherein two air paths are positioned at the upper side of plate lugs, the other two air paths are positioned at the lower side of the plate lugs, the air paths adjacent to the plate lugs and positioned at the upper parts of the plate lugs are horizontal while the other air paths are slant; and the slant angles alpha of the slant air paths are 20-40 degrees. By the improvement of adding the air paths, casting gates are reduced, improvements, such as arc radius R of a transition round angle part of the plate grid, and the like, are reduced,, and on the base of increasing neither production cost nor manufacturing difficulty of the die, the plate grid can effectively restrain the generation of the valve-control storage battery plate grid pores, so that the qualification rate of the products is improved by one to two percentage point, the loss rate of products and resource waste are reduced and the production cost is saved.
Description
Technical field
The utility model relates to a kind of mould, and particularly the grid mould of check valve control storage battery grid pore generation belongs to the battery technology field.
Background technology
Grid is the critical component of analysing valve control type lead-acid accumulator battery, is bearing the effect of supporting active material, delivered current in battery.The grid that valve-control storage battery uses is thicker, it generally is starting 2～3 times of battery, grid material is a Pb-Ca-Sn-Al alloy, the casting character of this alloy material is relatively poor, mobile bad, forming area is narrow, and gas is difficult for discharging in die cavity during casting, entrained air bubbles in when easily causing grid to be shaped, thus pore formed.In use sulfuric acid electrolyte very easily enters the grid deep layer by pore, and its corrosion rate is accelerated, and battery finally can not lose efficacy by conductive electric current because of grid, had shortened battery life greatly.For solving air bubble problem, the grid casting die has been proposed harsh requirement, in some large mold exhaust ventilation is set, with air in the abundant eliminating die cavity.Though said method can solve grid casting air bubble problem preferably,, be difficult for enforcement in general battery manufacturer man, so fail generally to promote the use of in battery enterprise because of mould manufacturing and grid production link specification requirement height, production cost height.
The utility model content
The utility model is used to overcome the defective of above-mentioned prior art and a kind of grid quality that can effectively improve is provided, the grid mould that the check valve control storage battery grid pore of extending battery life generates.
The alleged problem of the utility model is solved by following technical scheme:
The grid mould that a kind of check valve control storage battery grid pore generates, the grid mould is provided with the casting groove with the grid form fit, casting groove top is provided with a row sprue gate, its special feature is: the described plate ear position that is positioned at casting groove both sides is provided with four air flues respectively, wherein two air flues are positioned at plate ear upside, two air flues are positioned at plate ear downside, air flue adjacent with the plate ear and that be positioned at plate ear top is horizontal air flue, other air flue is the inclination air flue, and the tilt angle alpha of inclination air flue is 20～40 degree.
The grid mould that above-mentioned check valve control storage battery grid pore generates, the back cut diameter at described sprue gate is 4 millimeters, lower port diameter is 2 millimeters.
The grid mould that above-mentioned check valve control storage battery grid pore generates, the arc radius R at two grid knuckles of described casting groove upside position half is the 3-5 millimeter.
The grid mould that above-mentioned check valve control storage battery grid pore generates, sprue gate, described both ends lays respectively at the edge of described knuckle.
The grid mould that above-mentioned check valve control storage battery grid pore generates, described casting groove bottom is provided with leg.
The utility model generates the pore problem to grid dies cavity architecture advances at check valve control storage battery grid pore, improve by the arc radius etc. of setting up air flue, strengthen the sprue gate and reducing grid knuckle position, can suppress pore produces, improve the grid quality, the process of extending battery life.Follow-up of quality shows, adopt the utility model mould, on the basis that does not increase production cost and mould manufacture difficulty basically, effective check valve control storage battery grid air holes, make the product accepted product percentage improve 1～2 percentage point, reduce the product loss rate and the wasting of resources, saved production cost.

Label is expressed as follows in the accompanying drawing: 1. grid mould; 2. plate ear position; 3. knuckle; 4. inclination air flue; 5. horizontal air flue; 6. sprue gate; 6-1. sprue gate, end; 7. casting groove; 8. leg.
The specific embodiment
The utility model is as follows to the improvement that the grid mould structure carries out:
1. referring to Fig. 1, plate ear position in casting groove 7 both sides is provided with four air flues up and down respectively, wherein two air flues are positioned at the downside that the upside of plate ear position 2, two air flues are positioned at plate ear position, air flue adjacent with plate ear position and that be positioned at top, plate ear position is horizontal air flue 5, other air flue is an inclination air flue 4, and the tilt angle alpha of inclination air flue is 20～40 degree.Increased the exhaust passage in grid dies cavity plate ear position, the air communication that plate ear position is generated is crossed the exhaust passage of setting up and is discharged, and makes the plate ear position exhaust that very easily produces pore unobstructed, has avoided freely not causing a large amount of pores because of exhaust.
Why the utility model is obliquely installed air flue or be horizontally disposed with, and its objective is that it is longer that plumbous liquid is filled with the time, easily shelters gas because of plate ear position is a horizontal groove, is designed to horizontal air flue and can shortens stroke, and the gas of generation can be discharged in time.And other air flues to be designed to air flue be because the gas that squeezes out can upwards move in the plumbous liquid casting process, be designed to pattern and can make the gas discharge of taking advantage of a situation.
2. referring to Fig. 1, Fig. 4, strengthen the flow area at sprue gate 6, thereby accelerated time plumbous flow.The back cut diameter at sprue gate 6 changes 4 millimeters into by original 2.5 millimeters, and lower port diameter changes 2 millimeters into by original 1 millimeter, improves back alloy liquid and can flow into grid casting groove fast, and the air that is trapped in dies cavity is discharged by row's agent and by air flue fast.
3. referring to Fig. 1, Fig. 2, the arc radius at two grid knuckles of casting groove upside position 3 has been carried out improving design.Before the improvement, arc radius R is 8～10mm, structure as shown in Figure 3 because R is excessive, alloy liquid long flow path, flow velocity is slow, the exhaust passage is not smooth, produces air trapping very easily herein, generates pore.Improving back arc radius R is 3～5mm, reduces arc radius, has shortened flow process, has reduced resistance, has accelerated flow velocity, and air is extruded away apace, and a part of gas can extrude by 8 place, angle.Owing to reduced the arc radius size, increased sprue gate, end 6-1 on knuckle top simultaneously, the alloy flow quantity is increased.
