Problems solved by technology

[0002] Current status of positive grid forming process for miner's lamp: At present, the traditional gravity casting grid is widely used in the production of positive grid for lead-acid miner's lamp battery. The grid produced by the traditional method has the following defects: 1. The structure is loose, and the resistance of the positive grid Poor corrosion ability, miner's lamp life is not long
2. The forming rate of the positive grid of gravity casting is low, and the production efficiency is not high
3. The alloy composition is severely burned and the alloy consumption is high
To some extent, traditional gravity casting has become the bottleneck of promoting new products, new technologies and improving the performance of miner's lamps

Embodiment Construction

[0013] The production method of using a die-casting machine to produce a miner's lamp positive grid. First, according to the shape and size of the miner's lamp grid, a die-casting machine with a pressure in the range of 0-50MPa is selected, and a grid mold layout of eight pieces in one mold is used for die casting. Secondly, in the production process, the temperature of the lead pot alloy solution is adjusted to 400500 degrees, the lead outlet is controlled at 380-430 degrees, the mold temperature is controlled at 100-130 degrees, the injection time is controlled at 0.2-0.3 seconds, and the injection pressure is controlled At 100-150 bar, thirdly, the lead pot alloy solution is injected into the mold cavity through the injection system, and it is cast under high pressure. During die casting, the lead pot alloy solution is pressed into the mold cavity from below the liquid level.

Abstract

The present invention is process of producing positive plate grating for miner's lamp in a pressure casting machine. The positive plate grating is pressure cast with Pb-Al alloy liquid at 400-500 temperature inside a mold with eight plate grating cavities at 100-130 deg.c in a pressure casting machine of 0-50 MPa pressure, with the pouring time being 0.2-0.3 sec and pressure being 100-150 bar. The cast positive plate grating has compact structure, smooth surface, high density, high corrosion resistance and high flexibility.
