Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to (1) a method for molding a cosmetic bar such as a lipstick, a method for molding and dispersing the cosmetic bar, and a method for assembling the molded cosmetic bar into an extrusion container; The purpose is to form bar-shaped cosmetics inexpensively and accurately.

Another object is to accurately and quickly achieve cooling solidification of S-shaped cosmetics.

Another purpose of the trench is to safely attach the molded cosmetic bar to the extrusion container without damaging it.

Recently, stick-shaped products such as lip rouge are generally produced by using temperature-colored pieces of oozeve, which are then assembled into a saucer of an extrusion container. The material is injected, cooled and solidified to form bar-shaped cosmetics.
Thereafter, this oil was removed to achieve f[1] in the extruded container of bar-shaped cosmetics.

In the case of the above-mentioned conventional molding of bar-shaped cosmetics.

After the molding of cosmetics, a component called tidie is required (which becomes unnecessary), and prior to molding, it must be evenly and more firmly assembled into the extruded container, which is an independent component, in a certain mutual posture and orientation. In addition, after molding, make it possible to easily remove the odie from the extrusion container, and be careful not to damage the bar-shaped cosmetic product by the odie that is released. The need is β.

Furthermore, since Ozibe is molded from synthetic resin, it has poor heat conductivity, and as a result, it takes a relatively long time to cool and solidify the molten cosmetic material filled and injected, and it also requires strong cooling power. was there.

Due to the above-mentioned problems, in the conventional molding of bar-shaped cosmetics using Ozibe, or in order to mold one bar-shaped cosmetic and attach the silk to the extrusion container, there are high equipment costs, time required in the molding building, and It has many disadvantages, such as a large number of process steps and a relatively high rate of defects.

The present invention was devised to eliminate the drawbacks of the above-mentioned conventional examples, and the present invention will be explained below with reference to the drawings.

The molding force method for the bar-shaped cosmetic product 8 according to the present invention is the Hori-type! To,
This hori type! A molding hole 2 which is open on the upper surface and forms the mold surface of the cosmetic product 8 is cut and formed, and a cylindrical spacer 7 is fitted into the opening of the molding hole 2 with a string, Through this spacer 7, the molten cosmetic material is injected into the molding hole 2 through the injection nozzle 6, and then the injected cosmetic material is cooled and solidified to form a cosmetic product 8. That's what I do.

Cosmetic material injected into the molding hole 2, j
,;) Gold A, which has high thermal conductivity, is used to efficiently and summya VC.
It's better to mold it with IJ.
It is preferable to have a vertically elongated hole structure forming a tapered mold surface whose diameter gradually increases as it approaches the opening so that the coated cosmetics B can be smoothly drawn out from the two molding holes.

Further, the spacer 7 is fixedly fixed at 1θ in the opening part of the molded hole 2.
ξThere is a membership fee to be attached, but as a means of firmly inserting the button into the opening of the molding hole 2 of the spacer 7, the spacer 7 itself must be tightly fitted into the opening of the molding hole 2. 5K may be used, or another member may be used that immovably maintains the position of the spacer 7 once assembled into the opening of the molding hole 2.

In this way, the method for molding the bar-shaped cosmetic product 8 according to the present invention is as follows:
Since the molding hole 2 is formed in the mold 1 made of the same material as the commonly used material t, a uniform cosmetic 8 can be molded and the cosmetic material injected. Because it can act powerfully and efficiently as a cooling agent.

Heat control over cosmetic materials can be achieved quickly, accurately and easily.

Furthermore, since the cosmetic product 8 is assembled to the spacer 7 at one point after the molding is completed, the cosmetic product 8 is extracted from the molding hole 2 by applying a withdrawal force to the spacer 7. This makes cosmetics 8 gJ
You can smoothly pull out 8 cosmetics from the 2 yen molding holes without rubbing them.

Next, an example of a molding apparatus that more effectively implements the above-described method for molding bar-shaped cosmetics will be described.

A molding hole 2 with an opening E7 is cut in the upper surface of the molding mold 1 in a molding mold 1 made of gold foil 1 having high thermal conductivity, and water is poured around the molding hole 2. A drilling mold 1 is constructed by drilling a cooling path 3 for tracing the cooling path.

A mold is dug from the molding hole 2 of the spacer 7 which has been assembled into the opening of the molding hole 2 on the top surface of the molding hole 2! A holding touch plate 4 is provided which holds the spacer 7 immovably with respect to the trench ml by holding the portion protruding from the upper surface.

In the illustrated example of hhj, the holding split plate 4 is mounted on the top surface of the trench mold 1, and slides on the top surface of the trench mold I to clamp the spacer 7. Further, on the upper surface of this holding side plate 4, there is provided a hole that reinforces the immovable holding of the spacer 7 against the mold l by this holding side plate 4, and also controls the injection operation of the cosmetic material into the molding hole 2 by the injection nozzle 6. A guide splitter 5 to achieve this smoothly is arranged to open and close in the same manner as the holding side plate 4.

A cooling fluid is constantly supplied to the cooling path 3 formed in the drilling burr 1, so that a strong cooling force can be quickly applied to the cosmetic material injected into the molding hole 2. It is being done.

In the case of the above-mentioned molding apparatus, the spacer 7 is placed at the opening of the molding hole 2 of the drilling mold l in a cooled state.

Place the tip end into the insertion position and assemble 9, then the holding side plate 4
Move forward, Horikata! Spacer 7 protruding from the upper surface of
The spacer 7 is held immovably relative to the excavation mold l by clamping the parts.

Once the holding of the spacer 7 by the holding side plate 4 is completed,
The injection nozzle 6 is lowered above the gap R4 of the spacer 7, and the molten cosmetic material is injected and filled into the molding hole 2 through the spacer 7.

At this time, the cosmetic material injected into the molding hole 2 needs to reach approximately the middle height position of the spacer 7 which is fitted and assembled into the opening of the molding hole 2.

This is to ensure that the spacer 1 and the cosmetic product 8, which has been cooled and solidified and molded, can be assembled stably with sufficient strength.

In order to further increase the assembly strength between the cooled and solidified cosmetics B and the spacer 7, as shown in the embodiment shown in FIG.

It is preferable to provide several holding protrusions protruding from the inner circumferential surface of the tip of the spacer 7 into which the cosmetic 8 is inserted.

In this way, the 1M cosmetic material is injected into the molding hole 2 formed in the drilled car, which is constantly cooled, and is cooled and solidified, so a strong cooling force is applied to the cosmetic material. It can be made to work efficiently, so that high quality cosmetics 8 can be molded in a short time.

Dimensions. Since the molding hole 2 that forms the mold surface of the cosmetic product 8 is cut directly into the drilling mold l, there is no possibility of dimensional deviation due to thermal deformation, and as a result, the cosmetic product 8 can be produced with extremely high dimensional accuracy. Since a large number of molding holes 2 can be arranged in parallel in a single mold l, a large number of cosmetic products 8 can be molded in a short time, and the space of the entire device can be saved. It can be made small.

The cosmetic product 8 molded as described above is assembled to the spacer 7 at the same time as the molding is completed.

The spacer 7 is used to handle the cosmetic product 8 after molding, that is, to release it from the mold l and assemble it into the extrusion container 9.
This can be achieved by applying an external force to .

There is no need to directly contact the molded cosmetic 8, and therefore there is no risk of damaging the surface of the cosmetic 8.

Various methods can be considered for assembling the molded cosmetic 8 into the extrusion container 9. It is advantageous to assemble the cosmetic product 8 into the extrusion container 9 via the spacer 7 while the combination remains assembled in the digging mold (2).

In other words, the spacer 7 is a moat type by itself! If the cosmetic product 8 is molded securely, as shown in FIG. ,
The proximal end of the spacer 7 is assembled by fitting the receiving plate of the extrusion container 9 which is at its upper limit into the upper end, as shown in FIG.

The extrusion container 9 is raised as it is, and the cosmetic product B and the spacer 7 are released from the mold, and at the same time, the cosmetic product 8 is assembled into the extrusion container 9.

In addition, if there is any concern about the spacer 7 being firmly attached to the trench l, as shown in FIG. 4.

The holding side plate 4 is manufactured in advance in a structure that does not interfere with the fitting assembly between the spacer 7 and the saucer, and the spacer 7 is held between the holding plate 4 and the spacer 7 and the extrusion plate are held together. Achieved assembly with the saucer.

Thereafter, the holding part 4 is retracted and the extrusion container 9 is raised to form the cosmetic product 8.

In this way, the silk attachment of the silk combination of the cosmetic product 8 and the spacer 7 to the extrusion container 9 is accomplished in a state in which the combination of the cosmetic product 8 and the spacer 7 is assembled in the hole mold l. Since there is no need to hang up the product of the cosmetic product 8 and the spacer 7, the extrusion container of the silk product of the cosmetic product 8 and the spacer 7 can be made extremely safely with a simple operation. 9 can be achieved, and the p1# shield from the hole 5t of the cosmetic product 8 only displaces the extrusion container 9 upward.

Alternatively, you can leave the main body of the extrusion container 9 as it is and move only the saucer downward (upward displacement in the figure).
It is possible to achieve Pl(Bpη) extremely safely.

As is clear from the above explanation, the present invention allows bar-shaped cosmetics to be molded into good quality in an extremely short time, and -! The operation of the mold is simple, and the device is not only simple in structure, but also capable of molding a large number of cosmetic products in a small space.

Furthermore, what temperature is required for cosmetic molding? Ii! It is possible to easily, accurately and powerfully control the product, and it is also extremely safe to transfer cosmetics into extruded containers. It has many excellent functions and effects.
