Coreshooter "B40 GSE-I-XL"

AUTOMATIC SAND-CORE MACHINE "B 40 GSE-I-XL"

This machine is equipped as standard with intelligent hydraulic clamping units featuring grooved plates for closing vertically divided sand core boxes, moved by oleodynamic cylinders with an automatic position recognition system. The hydraulically controlled sliding unit allows the clamping unit with the installed sand core box to be moved out of the shooting and gasification position, enabling the operator to have free access to the top of the sand core box, thus allowing for the removal of hardened cores from the shooting area.

The sand-core machine in question is designed for the production of sand cores using gasification processes to harden the cores, and it is built with the following features:

• Clamping units on both the right and left sides with a mechanical fastening system for sand core boxes, independent hydraulic movements, and position recognition systems on both sides, controlled by hydraulic valves equipped with fast/slow modes and dedicated software.

• Hydraulically controlled sliding unit with a 600 mm stroke, realized through an oleodynamic cylinder and equipped with proximity limit switches.

• Hydraulic extractor: the vertical ejection movement with four push points and a 20 mm stroke is hydraulically self-guided and is fully housed within the base of the clamping unit with no visible external parts. This particular construction does not obstruct the normal use of the clamping unit when the extractor is not in use. The extractor's operation is always managed within the machine recipes, allowing it to be easily included or excluded as desired.

• Hydraulic table lift/lower unit realized with a hydraulic cylinder and a position recognition system, controlled by hydraulic valves with fast/slow modes and dedicated software.

• Large-capacity conical vibrating hopper (optional).

• OP 277 display and multifunction operational software (optional): The use of this operator panel and its software provides optimal performance, resulting in a simpler and more intuitive user experience. Additionally, the full-color graphic display aids operators in various machine-related tasks. The software allows storage of at least 400 sand core box codes with their respective operating recipes, which can be loaded directly by "name" or operational code.

• Complete perimeter closure, large enough to allow the sliding unit to move the entire clamping unit out of the shooting head while remaining within the enclosure. It features full-height, automatically operated operator-side doors. For maintenance, the perimeter closure includes side sliding doors controlled by safety limit switches. The front part of the enclosure is elevated to allow the handling of taller cores, such as those required by this client.

• Mechanical supports for the upper half of the sand core when using horizontally divided sand core boxes (optional).

• Integrated gasifier (optional) within the perimeter closure.

• Integrated electrical panel, with the operator control panel mounted on an articulated arm. It includes a Siemens S7-300 PLC and multilingual operational software with storable recipes and the following configurable settings:

  1. Indication of the type of shooting head to be used (slot, central hole, cross, or inserts).
  2. Indication of the type of insert to use (e.g., insert 11, etc.).
  3. Single, double, or triple shooting, each with its own charge time.
  4. Loading frequency.
  5. Indication of the shooting pressure to be used (manual adjustment).
  6. Position of the right sand core half.
  7. Position of the left sand core half.
  8. Position of the sand core during ascent (against the shooting head). Once this value is set, the machine automatically positions itself for the gasification plate's entry after shooting.
  9. Gasification time.
  10. Washing time.
  11. Indication of the gasification pressure to be used (manual adjustment).
  12. Indication of the washing pressure to be used (manual adjustment).
  13. Sliding unit enabled or disabled.
  14. Clamping units enabled or disabled.
  15. Ability to insert an intermediate stop in the cycle for the introduction of reinforcement or hooks before the shooting cycle.
  16. Ability to insert an intermediate stop in the cycle for the introduction of reinforcement or hooks after the shooting cycle.
  17. Option to enable the "extra-long core box" mode, allowing the sliding unit to move before the door closure at the beginning of the cycle and after the door opening at the end of the cycle. This enables the use of very deep core boxes that would otherwise interfere with the front doors under normal operating conditions.

The filterless shooting system used in this machine allows it to operate at reduced shooting pressures. The machine is built in compliance with European safety standards, is marked with CE certification, and is accompanied by the relevant declaration of conformity.
