Description

Separated coloring aids

The present invention relates to a teaching aid (coloring) for children, to shape a specific object shape, but the paper surface of the three-dimensional molded object made of the material using a mold to paint the children can express the object It is about the three-dimensional coloring teaching parish.

The present invention relates to the improvement of the known 'color learning teaching aid (the applicant's domestic registered utility model No. 0230647)' and 'low pollution pollution learning teaching aid' (domestic registration utility model No. 0287143).

In the case of the two known technologies, when a model of an animal or the like is made of clay, the model can maintain its strength only when the inside is completely filled or has a sufficient flesh thickness. It was a disadvantage that the consumption of paper porridge becomes a material.

In addition, even if you install a light bulb inside the model and decorate the model painted by illuminating the light, the effect of the light is almost outside of the model.

Of course, if the vacuum molding using the white PVC material can effectively see the light of the bulb installed inside, the model using the PVC material has a disadvantage of not using watercolor paint, and the children's finger movements It is preferable to use a brush to paint the learning and three-dimensional model, and from the environmentally friendly point of view, the material of the model is preferably paper porridge rather than PVC.

In order to solve the above problems, the present invention used reinforcement means to maintain the strength while keeping the thickness of the paper porridge forming the wall of the model sufficiently thin, and the model was divided into parts to facilitate insertion of the reinforcement means. By making the most of molding by dividing the model into parts, a separate auxiliary material can be used to effectively express the model that is difficult to express by only paper porridge molding.

Referring to the configuration of the present invention as described above in detail.

Conventionally, a three-dimensional molded article was manufactured by injecting paper porridge into a mold using an injector and pressing / drying.

In this design, however, each part of the three-dimensional molded part is divided to be advantageous for molding. In the case of forming a puppy, the four parts of the foot and the tail are molded in the left / right / lower direction. In this case, the mold can be directly integrated in the mold, but productivity is reduced in the molding process, manufacturing cost of the mold, and drying time of the molded article. However, in the present invention, four parts of the dog's 'back part / belly part / left / right part (including leg) part' were separated into different molds, and each part was joined / glued to complete the model.

Referring to the accompanying drawings of the present invention as described in more detail as follows.

1 illustrates a molding process according to the present invention, and shows a longitudinal cross-sectional view of an example of a top / bottom mold for molding a fish model having a relatively simple shape.

In Fig. 1, reference numeral 1 denotes paper porridge, reference numeral 2 denotes a reinforcement material, reference numerals 10 and 20 denote upper and lower molds. The fish parts formed by the process of Figure 1 are shown in Fig. The parts are molded in a form separated into two parts on the left and right sides by terminating the center.

In FIG. 1, although a fish having a relatively simple form is taken as an example, the same method may be applied to a more complicated object.

Referring to Figure 1 in detail, one side of the fish (the fish has a symmetrical form, but because the shape of the head and tail is different, there should be a mold for the left / right side, respectively. A mold is added in a suitable amount to the bottom mold 20 in which the yaw part is formed to form the shape of the mold). The paper porridge 1 of the present invention mainly contains pulp or mulberry. It includes all of the known paper porridge made into a porridge by stirring / kneading in water. The paper porridge (1) may include subcomponents such as a binder and a bleach in addition to the main component.

The paper porridge (1) is an oval plate of a suitable thickness / size according to the shape of the lower mold 20 is placed on the upper surface of the lower mold 20, the flesh thickness of the molded part molding (5) is approximately 1 ~ 5mm range It is desirable to determine the amount of paper porridge (1) so that the inside of it is thick. If the thickness is thick, the strength of the model is sufficient, but when it is painted outside with watercolor paint, the absorption / drying of the paint is not good, and the thickness is too thick. Thinning causes bursting during molding and partial surface distortion during drying and shrinkage. Therefore, it is desirable that the flesh thickness be 0.5 mm or more.

In Figure 1, the paper porridge (1) is shown in the form of partially laid down along the shape of the lower mold 20 due to its own weight. The degree of dough of the paper leather (1) is different depending on the shape of the lower mold 20 It is good. That is, if the lower mold 20 has a lot of irregularities and has a complicated shape, it is preferable to appropriately increase the moisture content.

The reinforcing means (2) of a suitable size is placed on the paper porridge (1) put into the lower mold (20) again.

The reinforcing means 2 is to increase the strength of the parts molded of paper porridge, and may use a fiber, synthetic resin or metal mesh (army). The thickness of the network used as the reinforcing means is 1.0 mm in diameter. Do not pass, it is good to go.

The size and planar shape of the reinforcing means (2) depends on the shape of the lower mold 20, it is determined so as to be sufficiently covered over the necessary portion of the strength. The reinforcing means (2) is cut in a rough shape in advance Use it.

The molding of the part is performed by pressing the paper mold 1 by lowering the upper mold 10 from the upper side where the paper porridge 1 and the reinforcing means 2 are placed.

Since the descending depth of the mold 10 determines the flesh thickness of the partial molding 5, it is determined in consideration of the viscosity and density of the paper hide 1 and the degree of complexity of the shape to be made.

When the mold 10 presses the paper porridge (1), the reinforcing means (2) is inserted into close contact with the paper porridge, and once dried, serves as a core material as it is pressed. In particular, the reinforcing means (2) is a mesh (ami) In the case of) form paper porridge (1) is penetrated between the net.

Naturally, the surface shape of the upper mold 10 is determined according to the shape of the part to be made and the shape of the lower mold 20. The upper mold 10 is provided with an appropriate number of escape grooves 11, The groove 11 is intended to allow the pressure to be evenly applied when the paper porridge 1 is pressed and to be partially accommodated as the escape groove 11 when the amount of the paper porridge 1 is large. That is, the casting mold It is the part that produces similar effect to the pressure in Esau.

The arrow in FIG. 1 means the lowering of the upper mold 10.

2 is a perspective view of the partially formed article 5 according to FIG. 1.

The outer periphery of the partially molded part 5 as shown in FIG. 2, that is, a part where the top / bottom mold contacts the burr may be generated. This is a burr, which is removed by a trimming process to cut out unnecessary parts. Fig. 2 shows an example in which the burr 80 is generated in only one place. In Fig. 2, reference numeral 81 denotes a trimming line to which a tool for removing burr 80, such as a cutting blade, touches.

In addition, depending on the complexity of the shape of the partial molding (5) to be made, it is also possible to install a mill pin or the like used in the conventional mold forming method to facilitate the ejection from the lower mold 20 after pressing molding / drying.

The structure of the upper and lower molds may be simplified, but preferably, the lower mold 20 is made of a metal such as aluminum, or a Teflon-based synthetic resin material having heat resistance and water resistance. ) Is a structure that can be heated in the range of 80 ~ 110 ℃ when forming, the upper mold 10 is formed at a predetermined interval with a minute vent hole 70 over the entire surface at the same time the surface of the mold 10 The structure is covered with a fine linen cloth. The air vent 70 is made to release moisture, and the linen cloth 71 can prevent the paper porridge 1 from blocking the air vent 70.

In the drawings, only a part of the vent 70 is shown.

In the same manner as described above, the left side of the fish is also molded in a separate mold, and the left and right sides are joined together and glued together. Of course, the appearance of each partial molded product 5 should be trimmed before joining the left and right sides.

Fig. 3 shows the central planar cross-sectional view when the left and right partial moldings 5 are combined, that is, the portion A-A '. In Fig. 3, reference numeral 40 denotes an internal space of a fish model, and reference numeral 3 denotes a filler.

Filler (3) is filled with clay or paper porridge in the interior space (40) of the model when the model needs a proper weight. Depending on the type of model, for example, a model of a pagoda or a high model such as an elephant It is necessary to add weight to the bottom of the pagoda or to the leg of the elephant to give weight. In this case, the filling material 3 is filled before the partial molding 5 is bonded and bonded.

Reference numeral 4 denotes a surface where each of the partial moldings 5 abuts each other. The adhesive may be a starch paste or an ordinary paper glue paste.

And, the reinforcing means (2) can be used in a different form, Figure 4 shows an example produced in a specific form.

The reinforcing means (2-a) of Figure 4 is a shape of the bones of the fish, it was made of a suitable curved surface along the shape of the inner surface of the partially molded article (5). Only those that can be used) are shown, but the corresponding parts are also applied to the opposite side-molded product.

The reinforcing means (2-a) is produced by iron plate press or synthetic resin injection molding.

In addition, both of the two types of reinforcing means (2,2-a) can also be applied to overlap, forming the appropriate irregularities in the mold 10, as shown in Figure 6 to reduce the flesh thickness difference of the paper porridge (1) In Fig. 6, reference numeral 90 denotes an example of reinforcing means formed by thickening the flesh thickness of the paper porridge 1. The shape is similar to that of fish bones.

Figure 5 shows the same coupling state as in Figure 3, but the state using a fish bone reinforcement (2-a). Advantages of using the reinforcement means (2-a) in the model interior space 40 When a lamp such as the little bulb 30 is installed and turned on, the shape of the fish bone can be checked from the outside of the model. This is the shape of the fish bone by turning on the little bulb 30 after children have properly colored the outside of the model. It also helps to identify and learn, and it also has the effect of promoting interest in color learning.

And, if the model is in the form of a house, the part corresponding to the window may be molded thinly, and the shape of the reinforcement means may be the shape of a person so that the shadow of the person may be seen inside the house model when the little bulb is turned on. .

Paper porridge (1) used in the production of the molded article to be applied to the little bulb 30 should be used that is not added to the earth powder or stone powder.

In Fig. 5, reference numeral 31 denotes a connection terminal with an external power source. When a parting object is enlarged, such as when a dinosaur model is manufactured, a battery, a switch, and the like may be simultaneously installed in the inner space 40 together with the little bulb 30. This may be a separate fixing member that is combined with the reinforcing means (2-a), and since the conventional technology can be any number, the description of how to install batteries, switches, lamps at the same time in the interior space 40 is omitted. do.

Arrows in FIG. 5 indicate the direction of power connection.

In the same way as above, a light and sturdy building model, a car model, or an animal model can be produced.

In addition, the partial molding (5) may not be provided in a combined state, and the partial molded articles (5) and the little bulbs (30) may be provided in separate states, respectively. By completing the molding, install the little bulb and coloring the outside of the model can increase the learning effect.

However, as described above, even if the paper porridge (1) alone is formed by separating the partial molding (5), it is difficult to express the thin fins of the goldfish or insects such as butterflies. However, as shown in FIG. Can be easily expressed.

As shown in FIG. 7, the auxiliary fastener 60 is formed in advance at one end of the molded part 5, and the auxiliary material 61 may be inserted and fixed through the auxiliary fastener 60.

The auxiliary material 61 is made of paper, resin film, or plastic wire. As shown in FIG. 7, paper or synthetic resin film is used for a portion corresponding to a wing of a butterfly, and a wire rod is used for a portion corresponding to an antenna. The auxiliary material 61 may be drawn in advance a sketch 100 for coloring the wing pattern of the butterfly. That is, both the partial molding (5), which is the body of the butterfly, or the auxiliary material (61), which is a wing, the material It's different, but it's a place for children to paint, but if it's difficult for children to paint, such as dragonflies' wings, you can use an auxiliary material preprinted with a dragonfly's vein on a plastic film.

The auxiliary material insertion hole 60 forms a gap as much as the thickness of the auxiliary material 61 at a corresponding position of the partial molding 5 so that the auxiliary material 61 and the partial molding 5 are in close contact with each other without forming a gap. It can be formed only on one side of the partial molding (5), or both can be formed. In addition, when the auxiliary material 61 is to be represented by a wire rod, such as antennae of insects, the auxiliary material insertion hole 60 is It becomes the form which formed only the opening part which fitted.

Joining of the auxiliary material 61 is preferably performed simultaneously with the adhesion of the partial molding (5).

The use of the auxiliary material 61 is effective when expressing fins of fish or whiskers of animals, and enables children to utilize wider teaching aids for coloring in three-dimensional objects.

The amount of paper porridge can be appropriately adjusted according to the form of the mold, and the model can be made firmly while the thickness of the flesh is thinner.

Models with a larger internal space can be produced than before, which is advantageous for the installation of small bulbs, and the external ventilation is good even when coloring the exterior with watercolor paints. When attached in the shape of a bone, etc. can be interesting by lighting the little bulb installed inside.

In addition, according to the type of model, by separately molding into an appropriate number of molded parts, the molding operation is easy, the defective rate can be reduced.

In addition, if the partial molding divided into several parts (5) as it is provided, the children themselves to cultivate each partial molding and to complete the model to cultivate the children's ability to solve themselves.

In addition, by using the auxiliary material to express things that are difficult to express only by paper porridge, and to make the coloring there, it increases the utilization of the coloring textbook.
