Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a stick-shaped cosmetic molding die, and more particularly to a molding die used for filling and molding stick-shaped cosmetics such as lipsticks and stick foundations.

[Conventional technology]

Conventionally, as such a rod-shaped cosmetic molding die, for example, a die composed of a flanged molding cylinder and a base with a hole for fitting the cylinder is known.

[Problems to be Solved by the Invention] However, in such a conventional mold, the fitting and holding of the molding cylinder and the base are merely performed by the seated engagement between the flange and the cylinder fitting insertion hole. Since it was not, it was difficult to rotate the molding cylinder, and it was virtually impossible to hold it.

Therefore, it is extremely difficult to set the position of the filling nozzle to the most preferable position with respect to the cut surface, particularly when filling and molding an asymmetrical bar-shaped cosmetic material such as a stick-shaped cosmetic material having a cut surface, and color unevenness is often observed. The actual situation was that a bar-shaped cosmetic with air holes at the tip was molded.

Further, because of such a problem, the conventional mold is very unsuitable for automation, and naturally the production efficiency is unavoidably deteriorated.

Therefore, as a result of various studies conducted by the present inventor to solve such a conventional problem, the present inventor has devised a present invention type capable of stably holding the molding cylinder and the base at a constant position. .

[Means for Solving the Problems]

That is, according to the present invention, a molding cylinder having a flange having a notch formed on the outer peripheral portion thereof, and a molding cylinder fitting having a locking projection engaging with the notch of the flange formed on the flange seating surface. It is a bar-shaped cosmetic molding die comprising a base for insertion and holding.

〔Example〕

 The present invention will be further described below with reference to the drawings illustrating the embodiments.

Reference numeral 1 is a molding cylinder for filling and molding a rod-shaped cosmetic material. The internal shape of the molding cylinder 1 is, for example, a cut surface 11 on one side of the tip, depending on the outer shape of the bar-shaped cosmetic material to be obtained.
(Figs. 1 and 2) or a cut surface 1 on both sides of the tip
Those having 1 (FIG. 3) and the like are appropriately selected. Further, on the outer peripheral portion of the upper opening of the molding cylinder 1, a flange 12 for seating and locking with a base 3, which will be described later, is provided so as to project outward.
The notch 12a is provided in a part thereof. For example, when the molding cylinder 1 has the asymmetrical cut surface 11 as described above, it is preferable that the cutout portion 12a is formed in the same direction as the cut surface 11 when the molding cylinder 1 has the asymmetrical cut surface 11. When there are a plurality of cut surfaces, a plurality of cut surfaces may be provided according to the number of cut surfaces, but even one cut may sufficiently attain the purpose. Furthermore, the notch 12a may have any specific shape, but may be, for example, a rectangular shape, a V-shape, or a semicircular shape, and the rectangular shape gives a good result in terms of fixing and holding property. It should be noted that the diameter of the flange 12 is the same regardless of the type of the internal shape of the molding cylinder 1, and if the diameter is the same, the base 3 described later can be shared by all the molding cylinders 1. Therefore, it is particularly advantageous.

Reference numeral 2 denotes an upper molding frame portion of the molding cylinder 1, which is removably attached to the upper opening of the molding cylinder 1 and may be used as it is as a bar-shaped cosmetic material holding middle plate (first (Figs. 1 and 2), or as the molding frame itself (Fig. 3), the inner plate may be separately attached after molding.

The flange 12 may be integrally formed with the molding cylinder 1 (FIGS. 1 and 2), but the flange 12 may be integrally molded on the lower outer periphery of the upper molding frame 2 and then fitted into the molding cylinder 1. It may be configured to be connected (Fig. 3). In this case, it is preferable that the fitting connection portion between the upper molding frame portion 2 and the molding cylinder 1 has a rotation preventing structure by an uneven fitting surface or the like as appropriate.

Reference numeral 3 denotes a base for inserting and holding a forming cylinder, which has an appropriate number of forming cylinder insertion holes 31 in the central portion. This hole 31
May be a mere straight through hole, and the upper surface of the base 3 itself may be the flange seating surface, but a stepped hole,
The lower surface is used as the flange seating surface 32, and the engaging projection 33 that engages with the notch 12a of the flange 12 is formed on the flange seating surface 32, which gives a good result in the fitting and inserting operation of the molding cylinder 1. . In this case, the side wall 34 extending from the upper surface of the base 3 to the flange seating surface 32, which is the lower surface, has a better result when it is an inclined surface that widens upward. Further, the hole 31 has a communication opening 35 at its upper portion to reach both end portions of the base 3.
This is particularly advantageous for smooth automation by a robot or the like. The height of the base 3 is appropriately selected according to the configuration of the filling and molding equipment, and the number and shape of the locking projections 33 are appropriately selected according to the shape of the cutout 12a of the flange 12, but especially on that side. The wall surface is preferably an inclined surface that expands downward.

[Action]

Since the present invention is configured as described above, the locking projection 33 formed on the flange seating surface 32 of the base 3 is
When the molding cylinder 1 is engaged with the base 3 while the cutout portion 12a of the flange 12 is fitted and inserted, the locking projection 33 and the cutout portion 12a of the flange 12 lock the molding cylinder body 1 together. 1 is held and fixed to the base 3 in a stable state without rotating.

Then, in such a state, the filling and molding of the stick-shaped cosmetic material is carried out according to a conventional method.

[Effect of device]

Therefore, according to the present invention, the molding cylinder 1 can be stably held and fixed to the base 3, so that the cosmetic filling operation can be performed extremely easily and reliably, and the work efficiency can be improved. .

In particular, when the molding cylinder 1 has the asymmetrical cut surface 11, the cutout portion 12a of the flange 12 is cut.
By aligning with the direction, the alignment with the locking projection 33 becomes extremely easy, and the cut surface 11 can be arranged and set at a constant position at all times. Therefore, the position of the filling nozzle can be stably set to the most preferable position. it can. Thus, by using the mold of the present invention, it is possible to prevent color unevenness and stick-shaped cosmetics having air holes at the tip thereof and to efficiently produce high-quality stick-shaped cosmetics.

Further, since all the flanges 12 of the molding cylinder 1 have the same diameter, it is possible to perform the filling and molding of the stick-shaped cosmetic material by using the same base 3 for the molding cylinders of various shapes. No need for a switching process on the line,
Further, handling of the molded cylinder by the robot becomes extremely easy. Thus, by using the mold of the present invention, it is possible to extremely advantageously automate the filling and molding of the stick-shaped cosmetic material.
