Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to molding dies, particularly injection dies, rubber dies, progressive press dies, press dies, die cast dies, vacuum forming dies, blow molding dies, etc. The present invention relates to a device that removes stains on the surface of a mold against various stains generated on the mold.

[0002]

2. Description of the Related Art A molding die is made of resin, rubber, die cast or the like as a raw material, and is burned by a gas generated during a molding operation to cause rust, various oxide films or stains. Occurs on the mold surface.

For example, in the case of an injection mold, stains and rust are generated on the surface of the mold due to a resin additive and a gas generated from the resin itself during high temperature molding.

If such dirt is left as it is, the molded product may become cloudy and the molded product may not be released from the mold at the end. Therefore, it is necessary to frequently perform cleaning work.

Therefore, in the past, in order to prevent the stains on the mold surface as described above, first, the cotton of the cotton swab was made to contain thinner or ethanol to remove the stains. However, since thinner and ethanol have no activity, the oil on the surface of the mold, a mold release agent such as silicon, and some dust can be removed. No oxide film could be removed.

For this reason, after using thinner or ethanol, a person's hand was used to polish with an abrasive such as diamond paste or chrome oxide.

[0007]

However, when the die surface is polished with diamond paste or chrome oxide, there is a direction of polishing, and it rubs in random directions, and even if the fingertip force is strong or weak. High-level polishing technology was necessary because it resulted in uneven polishing and uneven gloss, which ruined the mold. Also, delicate parts on the mold surface,
For example, a mirror surface portion, a hairline processed portion, a skin grain processed portion, and the like have a large number of thin and deep grooves, holes, and corners, which makes polishing work very difficult.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention provides
A rod-shaped handle having elasticity, which is a column or a polygonal column,
A large amount of 100% cotton is wrapped around one or both ends of the handle to form a cotton hat, and a cotton part impregnated with ascorbic acid or citric acid is used. A swab for removal is provided.

The present invention also has a rod-shaped handle having a columnar shape or a polygonal column and having elasticity, and a large number of 100% cotton cotton is wound around one or both ends of the handle to form a hat-shaped hat. A cotton swab for impregnation with ascorbic acid or citric acid and a cotton swab for deposit removal, and after moistening the cotton with water or kerosene, touch the cotton lightly. The present invention provides a method for removing a deposit on a die, which is characterized in that the deposit on the die is removed by lightly tapping or stroking.

The present invention will now be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing an embodiment of a swab for removing a deposit of a mold according to the present invention, and FIG. 2 shows a swab for removing a deposit of a mold of the present embodiment. It is the flowchart which showed the method until it removes the deposit of a metal mold | die using a cotton swab.

First, the structure of the swab for deposit removal of the mold according to this embodiment will be described with reference to FIG. In FIG. 1, reference numeral 1 denotes the entire swab for deposit removal of the mold,
2 is an elongated, elastic rod-shaped handle that is made of a resin such as plastic, wood, or paper made of 100% virgin pulp, and has a long and elastic rod shape. It is a cotton part that is wound into a cotton shape and impregnated with ascorbic acid or citric acid.

Here, the handle 2 is approximately 50 g in the central portion.
It is preferable that it has elasticity of a little over the weight of 2 mm to 3 mm, preferably 2.3 mm in diameter, and has a length of 3 denier from both ends of the handle 2 with a length of 80 mm to 15 mm each. Wrap a large number of 100% cotton with a length of 15 mm to 30 mm so that each side has a weight of 0.03 g.
Form a cone-shaped bottom with a hemispherical shape, such as from m to 6 mm, with the apex of the cone facing the center of the handle 2 so that the total weight is 0.2 g. A swab 1 for removing deposits of a mold is constructed. In this embodiment, the cotton part 3 is provided at both ends of the handle 2. However, the cotton part 3 may be provided only at one end of the handle 2. In this case, the total weight of the swab for deposit removal of the mold is obtained. Is the value obtained by subtracting the weight of the cotton on one side of the cotton from the above total weight of the swab for removing deposits of the mold.

Next, a method of impregnating the cotton of the cotton part 3 with ascorbic acid or citric acid will be described. When ascorbic acid is impregnated, since ascorbic acid is saturated, it is necessary to add 5 to water heated to 40 ° C to 50 ° C.
After dissolving 00 g / l of powdered ascorbic acid and completely dissolving it, each of the above cotton parts 3 was immersed in this aqueous solution for 10 to 15 seconds until the solution completely penetrated to the core of the cotton, and then from the aqueous solution. Remove and dry. In this way, when water is evaporated, ascorbic acid is evenly distributed from the cotton core of the cotton part 3 to the outer surface thereof.

When impregnating with citric acid, it is not necessary to heat water, and other than that, it is the same as in the case of ascorbic acid. In this way, the swab for deposit removal 1 of the mold is formed.

Next, a method for removing the deposit on the mold with the swab 1 for removing the deposit on the mold will be described with reference to the flowchart of FIG.

Steps S1 to S3 show a method for forming the swab 1 for removing deposits of a mold.
In step S1, cotton is wrapped around the handle 2 to form the cotton part 3, in step S2 the cotton of the cotton part 3 is impregnated with ascorbic acid or citric acid, and in step S3 the cotton part 3 is dried to deposit the mold. A swab 1 for removal is formed. The method for forming the swab for deposit removal 1 of the mold has already been described in detail in the description of the configuration of the swab for deposit removal 1 using FIG. Only described in.

Next, from step S4 and step S4 'and subsequent steps, a method for removing gas burning, rust, various oxide films and dirt on the surface of the mold using the swab 1 for removing deposits of the mold will be described. There is.

In case of cleaning the mold with water, in step S4, the cotton part 3 dried in step S3 is dried by about 7%.
Soak the cotton in water for 2 to 8 seconds to moisten the cotton.
Here, in the case of water, the speed of wetting of cotton is high, and water is contained in a relatively short time.

Next, in step S5, step S
In step 4, use a cotton swab 1 for removing deposits of a mold in which the cotton part 3 is soaked in water, and stroke 2 to 4 strokes on the surface of the mold where gas burns, rust, various oxide films and dirt are present. Clean by rubbing gently.

Here, after the cleaning treatment in step S5, if ascorbic acid or citric acid and water containing any of them remain in the treated area to some extent, the ascorbic acid or citric acid is acidic. When the cotton impregnated with these is moistened with water, the water becomes acidic with pH 3 for ascorbic acid and pH 1.5 for citric acid, causing rust to occur again. Or, it is necessary to completely remove citric acid and water containing either of them.

Then, in step S6, the ascorbic acid or citric acid remaining in the portion cleaned in step S5 and the water containing either of them are completely removed with cotton or tissue paper moistened with water. Perform post-treatment to remove.

Then, in step S7, a rust preventive agent such as oil is applied to perform rust preventive processing, and the mold cleaning operation is completed.

Next, the case of cleaning the mold with kerosene will be described. When kerosene is used, in step S4 ′, the cotton part 3 dried in step S3 is dipped in kerosene to wet the cotton with kerosene. Here, in the case of kerosene, the speed of wetting of cotton is slower than in the case of water, and it is necessary to immerse the cotton part 3 in kerosene for about 30 seconds, which is about four times that in the case of water.

Next, in step S5 ', the swab 1 for removing deposits of the mold containing kerosene in step S4'.
Then, clean the surface of the mold with gas burns, rust, various oxide films, and dirt by gently rubbing it from 4 to 8 strokes.

Thereafter, in step S7 ', a rust preventive agent such as oil is applied to carry out rust preventive treatment, and the mold cleaning operation is completed. It should be noted that it is even better to wipe off the portion subjected to the cleaning treatment before the rust prevention treatment, just in case.

As described above, when kerosene is used, since kerosene is an oil, it does not easily dissolve ascorbic acid or citric acid, and therefore kerosene itself does not become acidic and does not easily oxidize the mold surface. The post-treatment after removing the gas burning, rust, various oxide films and stains of the mold, which was necessary when using the above method, is unnecessary.

Needless to say, the shape of the swab for removing deposits of the mold according to the present invention is not limited to that shown in FIG. 1, and as shown in FIG.
45m from both ends of the handle 2'having a length of m and a length of 150mm
Up to the position of m, 100% cotton with a thickness of 3 denier and a length of 15 mm to 30 mm is 0.
Wrap a large number of pieces so that the weight becomes 3 g, and the cotton part 3'has a thickness A of 20 mm. The shape of the cone is like a hemispherical bottom, and the apex of the cone is directed toward the center of the handle 2 '. The cotton swab 1'for removing deposits of the mold may be formed so as to have a total weight of 1.4 g.

Further, when cleaning a relatively wide area, as shown in FIG. 4, the short side is 3 mm, the long side is 15 mm, and the length is 15.
18m from both ends of the handle 2 "that forms a 0mm square pillar
Up to m, 1g each of 100% cotton with a thickness of 3 denier and a length of 15 mm to 30 mm
A large number of wraps are made in the front and back to form the cotton part 3 ",
The die swab for deposit removal of the mold may be configured so that the total weight is from about 2 g to 5 g. In this way, the handle constituting the swab for deposit removal of the die has a polygonal column shape. It may have a rod shape.

Needless to say, in the cotton swab for deposit removal of the mold shown in FIGS. 3 and 4, the cotton parts are provided at both ends of the handle, but the cotton part may be provided only at one end of the handle. Of course, in this case, the total weight of the swabs for removing deposits of the mold is the value obtained by subtracting the weight of the cotton on one side from the total weight of the swabs for removing deposits of the mold.

Further, a commercially available cotton swab may be used, for example, cotton of a cotton swab commercially available from Heiwa Medic Co., Ltd. may be impregnated with ascorbic acid or citric acid as in the above-mentioned Examples. It is very easy to make the deposit swab of the present invention.

Furthermore, the ascorbic acid and citric acid used in the above examples are not special ones, and ascorbic acid is commercially available, for example, from Nakakita Yakuhin Co., Ltd. ) Is commercially available from.
