The conventional mold release agent spraying device has three systems of passages: a mold release agent liquid supply passage, a spray air supply passage, and a blow air supply passage, but these three passages are completely independent, Since the spray air supply passage and the blow air supply passage are configured to be switched by a solenoid valve, multiple release agent spray pipes are installed in the spray head that moves back and forth between the molds. If the device structure is equipped with a blow air blower pipe, there is a problem of oil dripping due to the release agent remaining in the release agent spray pipe and the spray pipe distribution passage hole dripping after spraying, and air leakage to the mold surface. The blowing air is specified only to the blow air blow pipe, and it is not possible to clean the mold surface over the entire area by blowing out the blow air from all the pipes of the air blow pipe and the release agent spray pipe at the same time. Since the spraying of the mold release agent cannot be stopped by supplying blowing air, there is a time lag between the stop of spraying the mold release agent and the spraying of the blowing air, which lengthens the time for one cycle of spraying and cleaning. There are other problems.

Furthermore, when blowing air is supplied from the air supply pipe 9 after the spraying of the mold release agent is finished, the blowing air is transferred from the air supply passage B (from the vertical vertical hole 28 of the fixed platen 3 to the vertical vertical hole 28 of the manifold 4). At the same time, a part of this blowing air passes through the air introduction passage hole D and enters the piston chamber 34. The piston valve 33 is moved forward to block the spray air introduction passage hole C. Therefore, the introduction of spray air into the valve chamber 21a of the piston valves 21, 21 for opening and closing the release agent liquid feeding passage is blocked, and the piston valves 21, 21 are moved forward by the biasing force of the spring 22. The mold release agent liquid feeding path O is now blocked. At the same time, a part of the blowing air that entered the blowing air introduction passage hole D of the controller 6 enters the gas-liquid passage passage hole E in the middle of the passage hole, opening the check valves 38 and 38'.
The blowing air passing through the check valve chambers 36, 36' flows through the distribution passage hole o2 of the release agent liquid feeding passage O (left and right horizontal vertical holes 17, 17' of the manifold 4 → the same distribution vertical vertical holes 18, 18'). The release agent remaining in the release agent distribution passage hole o2 and the release agent attached to the inner wall of each release agent spray pipe 10 are all discharged to the outside.

Note that the spraying of the mold release agent can be stopped by stopping the supply of spray air (in this case, by stopping the supply of spray air, the piston valves 21, 21 for opening and closing the mold release agent feeding passage are closed, and the mold release agent is stopped). (liquid feeding passage O is blocked), and a method for sending blowing air without stopping the spray air (in this case, a part of the blowing air enters the piston chamber 34 through the air introduction passage hole D, and the piston The valve 33 is operated forward to block the introduction passage hole C of the spray air, thereby blocking the introduction of the spray air into the valve chamber 21a of the piston valves 21, 21 for opening and closing the release agent liquid feeding passage. The piston valves 21, 21 are springs 22
In the latter case, the air for spraying and blowing flows through all of the release agent spray pipe 10 and air jet pipe 11. Since the air is ejected from the tubes at the same time, the mold surface can be well cleaned by powerful air blowing.

The mold release agent spraying device for a die casting machine of this invention has three passages in the spray head 1: a mold release agent liquid supply passage O, a spray air supply passage S, and a blow air supply passage B. However, a piston valve 21 for opening and closing the liquid feeding passage is provided in the supply side passage hole o1 of the mold release agent liquid feeding passage O leading to the spray pipe distribution passage hole o2, In the middle of the air introduction passage hole C through which a part of the spray air is introduced into the piston chamber 21a, an air introduction passage hole C is opened when the mold release agent is being sprayed, and when blowing air is ejected, a part of the blow air is introduced. A piston valve 33 for shutting off introduced air is provided, which is operated to shut off the introduction passage hole C, and a part of the blowing air is introduced into the piston chamber 34 through the introduction passage hole D and the release agent liquid feeding passage O. Spray pipe distribution passage hole o2
A gas-liquid passage through hole E that communicates between the mold release agent and the mold release agent is configured such that the through hole E is shut off when the mold release agent is sprayed, and when the blowing air is ejected, the through hole E is opened by introducing a part of the blowing air. Since the passage is configured with check valves 38 and 38' that are opened, switching control using spray air and blow air is possible, and when blow air is ejected, blow air is partially introduced into the passage. By flowing into the spray pipe distribution passage hole o2 of the mold release agent liquid feeding passage O through the hole D and the gas-liquid passage passage hole E, the spray remaining in this distribution passage hole o2 and each mold release agent spray pipe 10 Residual mold release agent can be blown out,
Therefore, it is possible to solve the problem of oil dripping in which the mold release agent remaining in the mold release agent spray pipe and the spray pipe distribution passage hole drips after being sprayed.

In addition, air can be blown onto the mold surface by simultaneously blowing air not only from the blow air pipe 11 but also from the entire group of air pipes 11 and the mold release agent spray pipe 10. The entire mold surface can be thoroughly cleaned.

Furthermore, since the spraying of the mold release agent can be stopped by supplying blowing air, there is no time lag between stopping the spraying of the mold release agent and blowing out the blowing air, reducing the spraying and cleaning time per cycle. It can be shortened and has excellent practical effects such as speeding up spraying and cleaning operations.
