SUMMARY OF THE INVENTION The use of the automatic manufacturing apparatus and the metal mold having the above-mentioned construction makes it possible to completely automate the steps of molding the rod-shaped cosmetic material and loading the container, thereby achieving a great rationalization. Is as described above. However, when filling the mold (10) with the bulk, the bulk is melted to about 100 ° C.
Water droplets (condensation) are likely to be generated on the mold (10), especially when a water cooling system is used for cooling.
However, there has been a problem that water droplets adhere to the inner surface and are likely to remain. Further, when the mold (10) is opened and closed by the mold opening device (16) and the gap opening device (17), water droplets easily adhere to various portions on the inner surface of the mold (10). Further, it is difficult to remove water droplets that have once adhered, and this problem has become even greater. That is, the bulk cosmetic is filled with water droplets adhered to the inner surface of the mold (10), and then cooled and solidified. It remains, and the appearance is impaired, resulting in a defective product.

In order to solve such a problem, the mold (10) is provided with the drain passage (101b) as described above, which is attached to the inner surface of the mold (104). It was not possible to completely remove the water droplets. Therefore, attempts have been made to manually remove water droplets adhering to the inner surface of the mold (10) by using an air gun or the like. Actually, water droplets were generated and stable removal of water droplets was not possible by manual operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made in consideration of the above-described circumstances, and is capable of reliably removing water droplets adhering to the inner surface of the metal mold without requiring any manual operation. It is intended to provide a device.

Means for Solving the Problems In order to achieve the above object, the apparatus for removing water droplets from a molding die according to the present invention has the following configuration. That is, a device for removing water droplets attached to a mold used for molding a stick-shaped cosmetic or the like,
A mold conveying means for conveying the mold in a predetermined direction; a mold stopping means for temporarily stopping the mold at a predetermined position on the mold conveying means; and a mold provided above the mold conveying means. A reciprocating mechanism that horizontally reciprocates one or more times along the transport direction of the mold, and a mold of the mold attached to the reciprocating mechanism and stopped by the mold stopping means in conjunction with the reciprocating mechanism. Air discharging means for blowing air obliquely from above toward the inner peripheral surface of the portion.

[0013]

In the apparatus for removing water droplets from a molding die according to the present invention, the die is conveyed in a predetermined direction by die conveying means, and at a predetermined position on the conveying means by die stopping means. It is temporarily stopped. A reciprocating mechanism that horizontally reciprocates one or more times along the mold conveying direction is provided above the mold conveying means, and the reciprocating mechanism includes an inner peripheral surface of a mold part of the mold. Air discharge means for blowing air from diagonally above is attached, so that the air discharge means blows air while reciprocating along the mold stopped by the mold stop means. In addition, water droplets adhered to the mold portion of the mold can be efficiently and uniformly removed.
