Problems solved by technology

[0013] Due to the high sand temperature, the large sand volume, the necessity of sand cooling to the specified temperature and the large space requirement of the furnace, the sand cycle is expensive, which further leads to the fact that the known production line is only large in a long production cycle. Operates economically when identical engine blocks are produced in series

Embodiment Construction

[0067] This production line comprises a core making unit 2 for manufacturing cores, a mold assembly unit 3 for assembling a mold G designed as a core box, a casting unit 4 for casting a molten aluminum alloy in the mold G, a A cooling unit 5a for the metal melt in G, and a stripping unit 5b for destructively removing the respective mold G and a quenching unit 5c for the casting M.

[0068] The core manufacturing unit 2 has a core injection station b and a transfer device 7 designed as a transfer section. The conveyor 7 is divided into four segments 7a, 7b, 7c, 7d which are arranged at right angles to each other so that they form the sides of a rectangle in plan view. Via a conveying section 7e arranged parallel to the shorter sections 7a, 7c, the upper part WO of the core mold can be conveyed to the section 7d. The core injection station 6 is here positioned in the corner region of the conveyor 7 where the segments 7a and 7d of the conveyor meet each other. In the core injec...

Abstract

The invention relates to a production line for the continuous production of cast parts (M) from a molten metal, in particular a molten light alloy. Said line comprises several functional units including a core production unit (2) for producing cast cores, a mould assembly unit (3) for mounting casting moulds (G) that are configured as core packets, a casting unit for casting the molten metal into the casting moulds (G), a cooling unit (5a) for cooling the molten metal that is contained in the respective casting moulds (G) and a demoulding unit (5b) for removing the casting mould (G) from the cast part (M), during which process the mould is destroyed. A production line of this type permits the economic and flexible production of heavy-duty cast parts with complex forms, in particular motor blocks. To achieve this, the successive continuous functional units (2 5b) are directly interconnected by a respective transport unit (12,19) and the rate at which the production line (1) ejects the finished cast parts (M) depends on the rate at which the core manufacture unit (2) delivers the cast cores it has produced.

Description

technical field [0001] The invention relates to a production line for the production of castings from a metal melt, in particular a light metal melt, in a continuous process, comprising a plurality of functional units, wherein a core injection and hardening unit is used for producing casting cores, a The mold assembly unit is used to assemble the mold designed as a core shell, a casting unit is used to pour the metal melt into the mold, a cooling unit is used to solidify the metal melt contained in the mold, a cooling unit is used for heat treatment Hardening by means of a mold and a stripping unit for early and destructive removal of the mold from the casting. [0002] The invention likewise relates to a method for the production of castings from a molten metal in a continuous process, wherein first casting cores are produced and then a casting mold designed as a core box is formed from the casting cores. The molten metal is cast in this mold. Next, the melt contained in th...
