Description

[Detailed description of the invention] (Industrial application field) This invention is a mold for molding stick-like cosmetics such as lipstick, and more specifically, a mold for molding stick-like cosmetics such as lipstick. This relates to molds for use.

(Prior art) In general, the third mold used when producing stick-shaped cosmetics by an automatic system is
A so-called split mold as shown in the figure is used. This mold 3 is composed of an upper divided mold part 31 and a lower fixed mold part 33, and hinges 35 attached to the sides of both can be opened left and right as shown by arrows in the figure. can. Inside this mold 3, a filling hole 37 is opened at the top surface.
are formed vertically and are arranged in parallel in the longitudinal direction of the mold. A pin hole 3 is provided on each end surface of the split mold part 31.
9 is formed in one pair on the left and right. A finger of a robot for holding the split mold part 31 which is operated by NC control (not shown) is fitted into this pin hole 39, and the operation of the finger opens the split mold part 31 to the left and right as shown by the arrows in the figure. When the part is in the closed state, the stick-shaped cosmetics filled in the filling hole 37 and not solidified are taken out by another robot.

By the way, in this type of mold, the split mold part 3
1, the operation of the robot becomes complicated. That is, when opening and closing the split mold part 31 with a pair of fingers forming the working terminal of the robot, the fingers are first located above the split mold part 31,
It descends at a predetermined timing and engages with a pin hole 39 formed in the split mold part 31. Then, the fingers move in a direction away from each other, that is, in opposite left and right directions, to open the split mold part.

When the split mold part is opened in this manner, the tail part of the stick-like cosmetic product is exposed above the filling hole 37 of the fixing part. After this, the process moves to the next process, and when the predetermined work is completed in this department, the fingers move toward each other, close the split mold part 31, and move on to the next bulk filling work. Then, this process is repeated one after another.
When a split mold as described above is used in an automatic manufacturing system for stick-like cosmetics, the disadvantage is that the NC control settings for the robot that opens and closes the split mold using fingers are complicated. .

(Purpose of the invention) This invention was proposed in view of the above-mentioned facts, and is intended to facilitate the setting of the NC control of the robot having the finger as the work terminal, that is, the movement (operation) setting of the finger. The purpose is to provide molds.

(Specific means for achieving the objective) The mold is separated into a fixed part and a movable part, and the fixed part is separated from the fixed part only when the movable part is moved upward relative to the fixed part. This is done by placing it on the machine.

(Embodiments) The embodiments of this invention will be described in more detail below based on the attached drawings.

1A and 1B show a first embodiment of this invention, in which filling holes 12 are arranged in parallel in the longitudinal direction in the lower fixing part 10, and filling holes 12 are arranged in parallel in the longitudinal direction on both ends of the fixing part 10, which will be described later. A guide pin 14 is implanted in order to position the movable part when it is loaded. The movable part 1 has a filling hole 13 and a guide hole 15 formed therethrough at positions corresponding to the filling hole 12 and the guide pin 14 of the fixed part 10, respectively, on the upper side.
1 is mounted in a state where it is positioned by a guide pin 10. In this state, both filling holes 12 and 13 are integrated, and the bulk is filled at this time.

Pole plungers 17 are inserted into both ends of the movable part in the longitudinal direction to prevent the movable part 11 from coming off when the fixed part guide pin 14 is inserted into the guide hole of the movable part. A plunger hole 16 is formed to be transparent. A locking groove 18 is also formed on the outer periphery of the guide pin so as to be locked by the tip of the plunger. The pole plunger 17 is connected to this plunger hole 1.
6. When inserted into the locking groove 18 and locked, the movable part 11 becomes locked to the fixed part 10.

This pole plunger 17 may be used if necessary during use of the mold, and its use is not mandatory. Since the guide pin 14 is inserted into the guide hole 15, the movable part does not slip off from the fixed part 10 during bulk filling. At a predetermined position on the longitudinal side of the movable part,
A locking hole 19 is formed into which the finger of the robot fits when the movable part 13 is removed from the fixed part 10 after bulk filling and solidification.

After solidifying the bulk filled into the filling holes 12 and 13, the stick cosmetic is easily inserted to expose the tail of the stick-shaped cosmetic, but at this time, it is necessary to remove the movable part 11.
In this case, the finger of the robot (not shown) located above the movable part 11 descends and fits into the finger locking hole 19, and then moves upward while the finger locks and holds the movable part. This leaves the tail of the staple cosmetic product exposed.

In a second embodiment of this invention, as shown in FIGS. 2A and 2B, filling holes 22 are arranged in parallel in the longitudinal direction of the lower fixing part 20. At both ends of the fixed part 20 in the longitudinal direction, a guide wall 24 is formed to hold the movable part 21 when the movable part 21 is mounted, in order to position the movable part described later when it is loaded onto the fixed part. It is set up. That is, the inner dimension of the guide wall is set to be the same as or slightly larger than the outer dimension of the end of the movable part that fits therein.

A filling hole 23 is formed through the movable part in the longitudinal direction, as in the first embodiment.
Reference numeral 29 in the figure is a locking hole into which the finger of the robot fits.

(Function) After the bulk is filled into a mold placed in a predetermined position with the movable parts 11 and 12 attached to the fixed parts 10 and 20, the bulk is cooled and solidified, and then the mold is placed above the movable parts. The fingers of a robot (not shown) located at the position lower and engage with locking holes 19 and 29 formed in the movable parts 11 and 21, thereby holding the movable parts. Thereafter, when the finger is raised, a so-called mold opening is performed, and the tail of the stay standing in the filling hole of the fixing part is exposed. After the stick-shaped cosmetics are taken out through a predetermined process, the finger descends to attach the movable part to the fixed part for the next bulk filling. In this case, guide hole 1
5. The movable part is tightly attached to the fixed part by the guide pin and the guide wall 24 so that the filling hole of the movable part and the filling hole of the fixed part are integrated.

(Effect of the invention) As described above, according to this invention, the fixing parts 10, 20
The movable parts can be removed and mounted simply by moving the movable parts 11 and 21 mounted on the top up and down with respect to the fixed part. In other words, the movement of the robot's finger is as simple as moving it up and down, and there is no need for the conventional movement of opening the split mold part, making it easier to set the NC control. It has the advantage of being Accordingly
This type of automatic manufacturing system for cosmetics using NC-controlled robots is very advantageous, and furthermore, it has the advantage that manufacturing costs are lower than conventional systems because it is easy to manufacture.
