Problems solved by technology

However, due to the mold and pressure of the grid casted by gravity, the surface of the semi-finished product produced is rough, the material density is low, and it is not resistant to corrosion. Therefore, the battery produced has a short service life and the discharge effect is not ideal.

Embodiment Construction

[0038] The whole machine of the present invention is shown in Figure 1 and Figure 2 and includes a lead pot part 1, a nozzle part 2, an eccentric pressing mechanism 3, a mold shifting mechanism 4, a hydraulic system 5, a water cooling system 6, a body 7, and a mold 8.

[0039] The first function of the lead pot part 1 is to melt the metal lead used to manufacture the product. Secondly, the hydraulic oil output from the hydraulic station drives the die-casting oil cylinder 23 installed in the lead pot part to complete the reciprocating motion. The die-casting oil cylinder pushes the lead liquid pump to melt. The resulting metallic lead is injected into the mold 8 through the runner 32 and the nozzle part 2 to produce a product that meets the requirements.

[0040] The power of the motor used in the hydraulic station is 5.5KW, which is used to drive the low-noise vane pump (model PV2R1F-23-F-RAA-F). The electrical control box (not shown in the figure) is used to control the die-cast...

Abstract

An automatic pressure caster for casting the grid plate of electric accumulator is composed of a lead smelting pot, a nozzle unit, an eccentric clamping unit with mould locking cylinder, a mould moving unit with mould moving cylinder, hydraulic system, water cooling system, machine body and mould set.

Description

Technical field [0001] The invention relates to a pressure casting equipment for the positive grid of a battery in the field of lead-acid battery production. Background technique [0002] In the manufacture of lead-acid batteries, due to technical requirements, some positive plates need to be filled with dust. The grids used in these positive plates are mostly produced by gravity casting. For grids cast by gravity, due to molds and pressure, the semi-finished products produced have rough surfaces, low material density, and are not corrosion resistant. Therefore, the battery produced has a short service life and unsatisfactory discharge effect. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a battery automatic grid die-casting machine, which adopts a pressure casting method, the die-cast grid surface is smooth, the material density is high, and the service life of the battery is improved. [0004] The automatic grid die...
