Description
Technical field
The utility model relates to storage battery production equipment technical fields, more particularly to a kind of grid casting die.
Background technique
Grid is not only the supporting body and skeleton of lead-acid accumulator active material, while the still confluence system of electric current, is
The main thoroughfare of electric current.So the quality of grid quality, determines the superiority and inferiority of battery performance to a certain extent.The spy of grid
The metallurgical structure of the composition of property and grid alloy object phase, content and its crystal is undivided.
The structure feature of Pb-Ca alloy grid, it is related with the working condition locating for it.The casting process condition of grid
Direct influence can be generated on the structure of grid rib.From daily Pb-Ca alloy green plate solidify after grid metallographic
From the point of view of examining situation, after the solidification is complete, the erosion profile and extent of corrosion otherness of grid are very for the grid of different structures
Greatly.That is casting condition will affect grid metallographic grain structure and final extent of corrosion.The oxygen of grid surface layer lead
It is that particularly important a process and active material can be with plates that grid surface, which forms corrosion layer, in change process or solidification process
Grid combine close and firm essential reason and main cause.Lead oxide after grid surface oxidation is deposited on grid surface layer, raw
It is long to enter lead plaster, one has thus been created between lead plaster and grid and has firmly been coupled very much, it is ensured that hereafter active material is close
It is attached on grid, active material is made to be unlikely to early fallout.
Metal is changed into solid process by liquid and is known as solidifying.Solid metallic after solidification is typically all crystal, so,
Again this process is known as crystallizing.Liquid to it is solid transformation be a sufficiently complex phase transition process.It is formed by after crystallization
Tissue, such as the shape of crystal grain, size, distribution, will largely effect on the machining property and service performance of metal, therefore,
Crystallization is a very important process.
Currently, the heating of Pb-Ca alloy grid casting die is heated to be mold dispatch from foreign news agency heat pipes heat heating mode, sound mould point
Two electrothermal tubes, cover half there She Zhi not be not 4 temperature probes up and down, and dynamic model only has heating device not have a temperature probe, in die cavity
Spraying release agent makes thermally conductive limited, thus causes difference quiet, in dynamic model temperature, in turn results in the grid rib for pouring and casting out
Difference on the structure of two sides, that is, the difference in the metallographic grain size of same grid rib front and back sides two sides；
The setting of existing casting process mold temperature, general die temperature are higher than 20 DEG C~30 DEG C of mould bottom temperature, this mould
Difference in tool top and the bottom temperature will also result in the difference on the single piece plate gate rib structure of same Dalian piece upper and lower part；
The recirculated water cooling of mold is the mold inner lead tubular type type of cooling, and cooling is ineffective, and partial cooling is too fast, makes
At structure generation difference that is uneven on entire mold temperature distribution, and then making respective panels gate rib in different zones；
In addition, since cooling water channel caliber is thinner, with the extension of working time, corrosion and water can be generated inside pipeline
Dirt further reduces caliber, and water flow reduces, and cooling effect more further deteriorates, and pipe internal corrosion is not easy with scale
It is difficult in maintenance in cleaning.
The grid cast out is poured according to current Pb-Ca alloy casting technique, rib structure otherness is very big, grid quality
Stability and consistency it is poor, in turn result in the difference after solidifying on grid corrosion layer, so as to cause between single battery single lattice,
Consistency is deteriorated between each monomer of stack battery, has seriously affected the integrated performance index of single battery and battery pack.

The interface setting of the parallel fixed half and moving half of the cooler bin, the size of cooler bin cover entire type chamber.
The cooler bin has multiple cooling water inlets and cooling water outlet, and cooling water inlet and cooling water outlet distinguish position
In on the two sides of cooler bin.
The cooling body further includes water inlet pipe and outlet pipe, and all cooling water inlets are connected to water inlet pipe, described
Cooling water outlet is connected to outlet pipe.
There is the demoulding thimble for crossing cover half on the cover half, there is the logical of evacuation demoulding thimble on the cooler bin in cover half
Hole.
Temperature sensor is equipped on the fixed half and moving half.
Multiple equally distributed temperature sensors are equipped on the fixed half and moving half.
The cooling body of the utility model grid casting die includes cooler bin, replaces the prior art using cooler bin
In snakelike cooling water pipe, increase the contact area of cooling body and fixed half and moving half, while the flow that is passed through of cooling water can be with
The path for greatly increasing and flowing through substantially reduces, and cools down everywhere more uniform, and snakelike cooling water pipe cooling water flows through path length,
Temperature obviously increases cooling water from the inlet to the outlet, make everywhere inhomogeneous cooling it is even, and cooler bin can facilitate in the utility model
