Background

At present, the known die casting die is provided with a slag ladle structure at the tail end of a punch die for collecting cold materials and gases at the front end, and finally the cold materials and the gases are gathered into a vacuumizing exhaust wave plate or a vacuum valve through an exhaust passage. In view of the design of the die, especially a large complex die-casting die with a sliding block, the exhaust passage can be arranged on the side of the static die. Because the structure restriction of die casting machine, quiet mould side does not have ejection mechanism, in actual production process, often takes place the condition that exhaust passage glues at quiet mould, in case take place this problem, can only shut down the manual work and get into the clearance in the board. A common solution is to increase the draft angle of the aisle. The scheme is effective for a smooth exhaust passage structure, but along with the mature application of a mechanical vacuum system of the die-casting die, the requirement on the exhaust passage is also increased to the requirement that the aluminum liquid needs to be decelerated and buffered at the same time, which means that the conventional smooth exhaust passage structure is replaced by more and more complicated exhaust passages with more turns. The conventional inclination increasing method cannot effectively solve the problem that the exhaust passage of the current large-scale complex die-casting die with the sliding block is adhered to the static die through the front production surface.

Detailed Description

Referring to fig. 1 and 2, the die-casting die static die ejection integrated device comprises an ejection block 1, a first reset rod 2, a second reset rod 3, an ejection rod 4, a compression spring 5, a copper pad guide sleeve 6, an ejector rod plug 9, a first reset rod plug 10 and a second reset rod plug 11.

The ejection block 1 is arranged on the back surface of the die body 7 and can have a moving ejection stroke in the die frame 8. The upper end of the ejection block 1 is provided with a diameter matched with the inner diameter of the compression spring 5 and used for limiting the spring to keep axial compression and not bend; the lower end of the compression spring 5 is matched with the ejection block 1, the upper end of the compression spring is matched with the copper pad guide sleeve 6, the compression spring is pre-tightened and compressed in the compression spring, the distance between the copper pad guide sleeve 6 and the ejection block 1 is limited by the die body 1 and the die frame 8, the compression spring 5 is pre-tightened and compressed in the compression spring, and the top guide section of the ejection block 1 and the copper pad guide sleeve 6 have the functions of guiding and positioning.
