Abstract

The present invention provides a spraying device of a die casting machine, which can easily set and confirm the spraying position even if the spraying position of a release agent is increased. A spraying device (16) for spraying a release agent or the like onto the inner surfaces of a fixed die (34) and a movable die (36) of a die casting machine (10) constituting a die cavity (38) is composed of a spraying nozzle (60), a moving device (62), a monitoring device (64), and a control device (18), wherein the spraying nozzle (60) sprays the release agent or the like, the moving device (62) moves the spraying nozzle (60) to a predetermined position, the monitoring device (64) is used for setting the moving path and the spraying position of the spraying nozzle (60), and the control device (18) moves the spraying nozzle (60) based on the setting. The monitoring device (64) displays the movement path of the injection nozzle (60) moving in the one-injection process.

Description

Spraying device of die casting machine Technical Field The present invention relates to a spraying device for spraying a release agent or the like onto an inner surface of a cavity in a die casting machine for injecting a melt into the cavity and casting a cast product. Background In a conventional die casting machine, a molten metal such as an aluminum alloy melted in a melting furnace is poured into a pouring ladle for each injection, the poured molten metal is poured into a pouring port of an injection sleeve, and the molten metal is injected into a cavity in a mold by a forward movement of an injection plunger disposed in the injection sleeve so as to be able to advance and retreat. After the casting is completed and the cast product is taken out from the mold, the next injection filling is prepared, and a release agent or the like is sprayed to the inner surface of the cavity by using a spraying device. By spraying a release agent or the like on the inner surface of the cavity in advance, the next cast product can be easily taken out. The spraying device is inserted between the fixed mold and the movable mold in an opened state and separated from each other, and sprays a release agent or the like to the fixed mold and the movable mold at appropriate vertical positions when inserted from above to below, for example (for example, japanese patent application laid-open No. 6-83149). Disclosure of Invention However, in the conventional spray device of the die casting machine, if the position of the release agent or the like to be sprayed in one spraying step is increased so that, for example, the spray nozzle is not only positioned in the up-down direction but also moved on a plane, setting and confirmation of the spray position become difficult, and there is a problem that it is actually necessary to operate the spray device in order to confirm whether or not the setting is correct. The present invention has been made in view of the above problems, and an object of the present invention is to provide a spraying device for a die casting machine, which can easily set and confirm a spraying position of a release agent or the like even if the spraying position is increased. According to one aspect of the present invention, there is provided a spray device for a die casting machine for spraying a release agent or the like onto inner surfaces of a fixed die and a movable die of the die casting machine constituting a cavity, the spray device comprising: A spray nozzle that sprays the release agent and the like; A moving device that moves the injection nozzle to a predetermined position; A monitor for setting the moving path and the injection position of the injection nozzle, and A control device that moves the injection nozzle based on the setting, The monitoring device displays the moving path of the injection nozzle in the one-time injection process. Preferably, the current position mark of the spray nozzle is displayed on the moving path. Preferably, the current position mark is displayed only by moving the monitor along the movement path without moving the ejection nozzle in the moving means. Preferably, in each position on the movement path, the content of each ejection action of the ejection nozzle is displayed on the current position mark. Preferably, the movement speed of the injection nozzle can be set individually in each position on the movement path. According to the spraying device for a die casting machine of the present invention, since the movement path of the spray nozzle in the one-shot spraying step is displayed on the monitor device, even if the spraying position of the release agent or the like is increased, the setting and confirmation of the spraying position can be easily performed.
