Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a spray device for spraying a mold release agent and like on an inner surface of a cavity in a die casting machine that injects molten metal into the cavity for casting cast products. Description of the Related Art In die casting machines used from the past, molten metal, such as an aluminum alloy, molten in a melting furnace is measured and drawn up with a ladle for each shot and the molten metal thus drawn up is poured to a pouring inlet of an injection sleeve, and then the molten metal is injected and filled into a cavity of a mold by forward movement operation of an injection plunger provided movably forward and backward in the injection sleeve, thereby casting cast products. After the casting is completed and a cast product is ejected from the mold, a mold release agent and like are sprayed on the inner surface of the cavity using a spray device in preparation for the next injection and filling. Spraying of the mold release agent and like on the inner surface of the cavity in advance has effects of facilitating ejection of the next cast product and the like. Such a spray device is, for example, inserted downward from above between a fixed mold and a movable mold that are opened and separated from each other and sprays a mold release agent and like on the fixed mold and the movable mold at an appropriate position in the up-down direction (e.g., PTL 1). PTL 1: Japanese Utility Model Publication H06-083149U (1994). SUMMARY OF THE INVENTION However, some of the spray devices of the die casting machines in the past are developed to have, for example, spray nozzles moving to the positions not only in the up-down direction but also in the planar direction, and the increase in the positions to spray a mold release agent and like for one spray process causes problems of making it difficult to set and check the spraying positions and also having to actually operate the spray device to check whether the setting is correct. In view of such a circumstance, one or more embodiments of the present disclosure provide a spray device of a die casting machine capable of readily setting and checking spraying positions even if the positions for spraying a mold release agent and like increase. A spray device of a die casting machine for spraying a mold release agent and like on inner surfaces of a fixed mold and a movable mold of the die casting machine, the inner surfaces constituting a cavity, the spray device according to an aspect of the present invention includes: a spray nozzle configured to spray the mold release agent and like;a moving device configured to move the spray nozzle to a predetermined position;a monitoring device configured to set a moving route and a spraying position of the spray nozzle; anda control device configured to cause the spray nozzle to move based on the setting, whereinthe monitoring device displays the moving route to move the spray nozzle for one spray process. It is preferred that a current position marker of the spray nozzle is displayed on the moving route. It is preferred that only the current position marker is moved and displayed along the moving route only on the monitoring device without moving the spray nozzle by the moving device. It is preferred that the current position marker displays details of various kinds of spraying operation of the spray nozzle at each position on the moving route. It is preferred that a moving speed of the spray nozzle is allowed to be individually set at each position on the moving route. The spray device of a die casting machine according to the present invention causes the moving route to move the spray nozzle for one spray process to be displayed on the monitoring device, and is thus capable of readily setting and checking the spraying positions even if the positions for spraying the mold release agent and like increase.
