Abstract: The present invention relates to a lead delivery apparatus (10) for a cast on strap machine arranged to deliver a predetermined volume of molten lead to a mould. The apparatus comprises a first needle valve (40), a second needle valve (50), and a housing (19). The housing (19) comprises a reservoir (30) having an inlet (31) and an outlet (32). The reservoir inlet (31) is in fluid communication with a molten lead supply. The reservoir (30) is supplied with molten lead during use such that the molten lead in the reservoir (30) is maintained at a constant height (34). The reservoir outlet (32) is defined in a lower portion of the reservoir (30) and is selectively openable and closable by the first needle valve (40). The apparatus (10) also comprises a volume block (20) having an inlet (22), an outlet (24) and a through cavity (26). The volume block inlet (22) is in fluid communication with the reservoir outlet (24), and the volume block inlet (22) is located below the reservoir outlet (24).

Abstract: The present invention generally relates to the forming of battery components and in particular, but not exclusively, to such apparatus for use in manufacturing cast on straps during the manufacture of batteries. More specifically the invention relates to a mould for forming battery components, a cast on strap machine for moulding battery components and a lead delivery apparatus for a cast on strap machine.

Abstract: A mold for molding post and strap in a cast on strap machine includes a mold body having an upper surface, a cavity in the upper surface for molding a strap and an opening aligned with the cavity for receiving a water-coolable insert for molding a post. The opening extends through the mold with its mouth in the upper surface to enable the insert to be inserted into the opening through the mouth. The mold body further includes a removable plate for being received in the mouth to retain releasably the insert in the opening and for defining the cavity.

Abstract: An apparatus for delivering a predetermined volume of lead to a mould includes a housing defining a lead reservoir having a lead outlet defined in its base and in communication with the reservoir. A runway is provided beneath the base, spaced from the base and generally parallel thereto. A block is provided slidably mounted between the base and the runway and defining a through cavity having the predetermined volume for receiving lead from the outlet in a first position and for releasing the lead in a second position. A mechanism is provided for reciprocating the block between the first and second positions. A cast on strap machine is also disclosed. A lead delivery apparatus comprising a delivery chute is also disclosed.
