Abstract
A moulding plant comprises a sandslinger 2 and a turnover and withdrawal mechanism mounted on a common bed. The turnover mechanism is made in the form of two disks spaced apart and coupled to a drive designed to turn the turnover and withdrawal apparatus in a vertical plane relative to their horizontal axes. Rigidly fixed between the disks are side-roller conveyers wherebetween is mounted a double-sided pattern plate with top and bottom patterns. The withdrawal mechanism comprises power cylinders for moving the pattern plate with the top and bottom patterns. Mounted on the bed are two side-roller conveyers designed for carrying empty moulding boxes to the turnover and withdrawal mechanism.
Claims12
A moulding plant comprising:
- a sandslinger;
- a turnover and withdrawal apparatus having a turnover mechanism and a pattern withdrawal mechanism, said turnover mechanism being made in the form of two disks spaced apart and coaxially mounted on rollers, which disks are connected with a drive designed to turn the turnover and withdrawal apparatus in a vertical plane about the horizontal axis of the disks, two roller conveyors mounted on crossmembers installed between the disks being located between said disks in symmetry with their horizontal axis and parallel thereto, said pattern withdrawal mechanism incorporated power cylinders disposed on the crossmembers between the turnover mechanism disks for the purpose of withdrawing patterns together with a pattern plate, wherein the sandslinger is located over the turnover and withdrawal apparatus with the possibility for horizontal reciprocating movement, the turnover and withdrawal apparatus being provided with a double-sided pattern plate both sides of which are designed for attachment of patterns for cope and drag moulding boxes carried by top and bottom roller conveyers respectively, said double-sided pattern plate being mounted for rotation together with the turnover and withdrawal apparatus and for vertical movement between the cope and drag moulding boxes in order to withdraw the pattern from the completed half-mould in one of the moulding boxes simultaneously with assembling the other moulding box with the respective pattern.
A moulding plant comprising:
- a rotatable turnover and withdrawal apparatus including a turnover mechanism and a pattern withdrawal mechanism formed of two spaced apart disks coaxially mounted on rollers, said turnover and withdrawal apparatus being provided with a double-sided pattern plate mounted for rotation with said turnover and withdrawal apparatus, both sides of said pattern plate being adapted for attachment of patterns for cope and drag moulding boxes, said double-sided pattern plate being mounted for movement vertically between said cope and drag moulding boxes;
- a sandslinger mounted above said turnover and withdrawal apparatus for horizontal reciprocating movements;
- a drive connected with said disks for turning said turnover and withdrawal apparatus in a vertical plane about the horizontal axis of said disks for movement of said double-sided pattern plate vertically between said cope and drag moulding boxes;
- a pair of upper roller conveyors and a pair of lower roller conveyors for carrying said cope and drag moulding boxes, each of said pair of roller conveyors being mounted on a cross member positioned between said disks in symmetry with the horizontal axis thereof and parellel thereto;
- and
- said pattern withdrawal mechanism including power cylinders disposed on the cross members between said disks for withdrawing the patterns together with the pattern plate.
