Background
In the long-term production link of the white area of the lost foam, the problem of automatic drainage of the upper die of the full-automatic lost foam die applied to a vertical forming machine is always a technical difficulty, and the excessive water which is not drained causes that the white die product produced by the lost foam die has high water content, directly influences the drying efficiency of the white die, and the excessive water directly flows to an operator area, thereby causing poor production environment of the white area and low working efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a mould drainage device on disappearance mould general type makes the cooling water of last mould in the mould discharge into mould inner circulating system through the make-up machine, reduces the water content in the white mould product, improves white district production environment.
The utility model adopts the following technical scheme for accomplishing the above purpose:
a general upper die drainage device for a lost foam die is characterized in that an upper die cavity of the lost foam die is a female die, and a lower die cavity of the lost foam die is a male die; the lowest point of the bottom surface of the upper die cavity is provided with a conical through hole, and the top surface of the lower die cavity is provided with a communication hole communicated with the conical through hole; the upper die cavity is communicated with the lower die cavity through a conical through hole and a communication hole; a pneumatic drainage mechanism which is used for enabling the upper die cavity and the lower die cavity to be mutually independent and opening the upper die during drainage is arranged corresponding to the conical through hole when the lost foam die is produced; the pneumatic drainage mechanism is provided with a magnetic cylinder; the output end of the magnetic cylinder is connected with a conical metal plug through a connecting rod, and the conical metal plug is matched with the conical through hole in the upper die cavity.
The pneumatic drainage mechanism is fixed on a top sealing plate of the upper model cavity, the magnetic cylinder is connected with a PLC control system on the forming machine through an air pipe and an induction line, the magnetic cylinder is in hard connection with the connecting rod through threads, and the connecting rod is in hard connection with the conical metal plug through threads.
The utility model provides a general type upper die drainage device of lost foam mould, through setting up the toper through-hole at the bottom surface minimum in upper mold cavity, and design the intercommunicating pore that communicates with the toper through-hole at the top surface in lower mold cavity, in the mould production process, make-up machine PLC system automatic control cylinder open and shut thus drive the metal end cap to open and shut, make upper die cavity and lower mold cavity realize UNICOM and isolation; the cooling water of the upper die can be automatically discharged through a drain outlet arranged at the lower part of the lower die mounting plate of the forming machine, so that a drain outlet arranged at the outer side of the lowest point of the upper die is omitted, a drain pipe of the forming machine is formed by independent manual connection, the problem that automatic production cannot be realized is solved, and the problem that the cooling water at the lowest point of an air chamber of the upper die of the die cannot be automatically discharged in the die making process is also solved.
