Precision Shell Molding Line for Comprehensive Machinery Sand Casting Line

Product Description

Coated sand shell/core casting line

Coated sand shell/core casting line is mainly composed of an automatic flask  loading system, flask conveying system, pouring system, sand shakeout system , shot and sand separation and cooling system, electronic control system,hydraulic system, pneumatic system, smoke treatment system, sand shakeout and screening, dust colecting system, etc.

The main process is as follows: the sand flask with cooling castings enters the flask  turnover unit to do. The flask turnover and sand shakeout, the hot old sand and shot enter the sand reclamation system, and the castings are taken from the sand shakeout machine  and scale machine. The shots after the automatic turnover are separated from the coated  shell through  the  vibration  conveyor, plate  chained elevator, and  automatic  screening machine. The shots are sent to the sand hopper after cooling. The sand hopper is equipped with a material level sensor to prevent overflow.

Many pneumatic automatic sand adding stations are set in the molding sand hopper. The sand adding equipment is automatically expanded to avoid sand dust overflow. The sand adding inlet is  equipped  with  dust  collecting  equipment, the  dust  collecting motor is synchronized with the sand adding, and   the pneumatic automatic sand adding station completes the same function. The manipulator puts the sand flasks on the trolleys  before  the  pouring  process, the  flasks  with  shells  will  be  transported  to  the  vibrating  station  to  do  the vibration  after  automatic  sand  adding  finishes.

The conveyor automatically pushes the finished shell sand mould to the pouring system for pouring, and the finished castings are transported by the ferry to the cooling station for cooling. It is the cycle of the molding line.

The production process of Coated sand shell/core casting line

1.Core setting is performed using manual or automated machinery.

2.Pre-filling, filling, and compaction: Pre-filling involves filling the sand box with steel shot to ensure that the height of the sand core pouring gate remains consistent; after the core is installed, steel shot is filled and compacted.

3.Casting: Methods include casting machine, ring track casting, and ladle casting.

4.Casting Cooling: After casting, the sand box is transferred to the cooling column by a transfer device, and the cooling time is set according to the actual needs of the product.

5.Automatic Box Tilting: After the set cooling time is reached, the sand box is transferred to the box tilting station to complete the automatic box tilting process.

6.Vibratory Sand Removal: Castings, waste sand, steel shot, and iron blocks are all fed into the sand removal machine; castings are vibrated and conveyed into the hopper.

7.Dust Collection Methods on the Production Line: Semi-enclosed or enclosed dust/odor removal methods are adopted for workstations such as pouring, transferring, turning, and cooling.

8. Dust removal and VOC catalytic combustion equipment: Pre-filling with steel shot in the sand box ensures consistent core gating height; after core placement, steel shot filling and compaction are performed.
