Description

technical field [0001] The invention relates to lead alloy grid casting equipment in the manufacture of lead-acid batteries, in particular to a flat-cut casting machine for producing lead alloy grids of lead-acid batteries. Background technique [0002] In the production process of lead-acid batteries, it is necessary to produce lead alloy grids with qualified dimensions, and the lead alloy grids are mainly produced by casting machines. The casting machine includes a high-level lead melting furnace (or a low-level lead melting furnace), a lead valve device, a lead spoon pouring mechanism, a mold opening and closing mechanism, a shaping and conveying mechanism, a grid slope positioning mechanism, an inclined cutter mold, and a grid Take-up mechanism and circulating water tank.

Problems solved by technology

[0003] At present, there are two kinds of known lead valves: a kind of lead valve is a cone-tip cone-face sealing valve exposed to the air. Lack of sealing leads to lead leakage and inaccurate quantitative lead supply; another kind of lead valve is a ceramic ball cone sealing valve embedded in the lead liquid. The valve core of this lead valve is installed in the pump body and locked with the valve core gland. When replacing the spool, the lead pipe and the whole lead pump must be unloaded first, and it is difficult to replace the spool

[0004] At present, the known cutting dies all use an angle of about 40-50° to cut off the process gate of the lead alloy grid. Before cutting, the positioning method of the lead alloy grid with the process gate is to locate on the inclined plane in the direction of the angle of 40-50° , the way for the lead alloy grid with process gate to enter the cutter mold is to rely on the weight of the lead alloy grid to overcome the friction force of the slope of the lower knife seat with an angle of 40-50°, then accelerate to slide down freely and hit the lower positioning When positioning the plate, the lead alloy grid freely accelerates and slides down obliquely and hits the lower positioning plate, which will cause a large deformation of the lead alloy grid.
