Generally, expandable polystyrene (EPS) products are widely used as general packaging materials in bead type foams. However, as the products are advanced and refined, The demand for improvement is increasing.

This is a substitute product that reinforces the physical (cracking, repetitive buffering) vulnerability of EPS products. PP (Polypropylene) resin is used as a raw material and it is more stable than EPS in terms of cracking, repeated buffering, flexibility and chemical resistance. EPP (Expanded Polypropylene) (hereinafter referred to as "EPP") has been developed, which is advantageous for the improvement of the packing density and the miniaturization of the packaging volume. Currently, EPS is used for general buffer packing containers, EPP is used.

The foam, such as EPS, EPP, etc., which is made of beads, is supplied to the molding space provided between the upper molding mold and the lower molding mold assembled from both sides, and the upper molding mold and the lower molding mold Wherein the upper mold and the lower mold are melted by a heating material such as steam supplied to a molding space through a steam cap inserted into a steam inlet hole formed through the mold, So that it is made into a molded product of a predetermined shape in the molding space.

In general, product molding dies such as foamed polypropylene (EPP), expanded polystyrene (EPS), foamed polyethylene (EPE) and Hanseran can be produced by using high pressure steam, such as EPP, EPS, EPE, Products Molding of products such as EPP, EPS, EPE, Hanseran, etc. of certain shape by fusion of EPP, EPS, EPE,

Since EPP, EPS, EPE and Hanselen products are more environmentally friendly than materials such as urethane, they can be used as handles especially for rims, sun visors for vehicles, , Functional parts for private use for the living and packaging boxes.

The EPP, EPS, EPE, and Hanselen products are also molded into a foam made of beads as raw materials, and are also supplied to a molding space provided between an upper molding mold and a lower molding mold assembled from both sides, The upper mold and the lower mold are melted by a heating material such as steam supplied to the molding space through the steam cap inserted in the steam inlet hole provided respectively through the upper molding mold and the lower molding mold, and at least one of the upper molding mold and the lower molding mold The mold is moved toward the opposed forming mold and is strongly pressed and formed into a molded product having a predetermined shape in the molding space.

When a molded article is completed by the conventional foamed foam forming mold having the above-described characteristics, it is general that a steam cap mark imprinted by the steam cap is formed on the surface of the molded article. However, the steam cap mark formed on such a molded product may act as a negative factor depending on the tendency of the demand.

On the other hand, it is necessary to form various marks such as a company name or a logo on the surface of the molded article as the case may be. However, since the conventional foam foam forming mold is difficult and complicated to manufacture the mold, it has not been possible to propose a foam foam forming mold capable of engraving the various marks.

As a result, when it is necessary to imprint various marks on the surface of the molded article, if the various marks are formed by utilizing the steam cap mark imprinted on the surface of the molded article, all the various needs of the consumer can be satisfied. However, such a technical feature has not been proposed so far, and a foam forming mold for achieving such a purpose has not been proposed yet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the foamed foam forming mold according to the present invention having the above-described problems, solutions and effects as described above will be described in detail with reference to the accompanying drawings.

The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator.

FIG. 1 is a schematic cross-sectional view of a foamed foam forming die according to an embodiment of the present invention. FIG. 2 and FIG. 3 are schematic views showing a state in which an ascending / descending plate applied to the present invention is inserted into an opening hole of a lower forming die, Fig. 4 is a perspective view showing the inside of the lower molding die, and Fig. 5 is a sectional view of a cutting state.

As shown in FIGS. 1 and 5, the foamed foam forming mold 100 according to the present invention includes an upper molding die (not shown in the drawing, an upper die mold described in the background of the invention) And a lower mold (10) and an elevating plate (30) arranged to be able to move up and down.

Also, the foamed foam forming mold according to the present invention is also characterized in that the raw material is supplied to a forming space provided between an upper forming mold (not shown) and a lower forming mold 10, And at least one of the upper molding die and the lower molding die is melted by a heating material such as steam supplied to the molding space through a steam cap inserted in a steam inlet hole formed through the upper molding die and the lower molding die, So that a molded product of a predetermined shape is produced in the molding space.

However, unlike the conventional lower molding die, the lower molding die 10 has an opening 11 formed on the lower side thereof. That is, the lower molding die 10 forms a molding space in a state where the upper molding die is inserted, and an opening hole 11 is formed in the lower side. The opening hole 11 is naturally maintained in a closed state during the molding process, and in the present invention, the lifting plate 30 is inserted to maintain the closed state.

The elevating plate 30 is basically arranged to be movable upward and downward. That is, the lifting plate 30 is arranged to be able to move up and down by the lifting and lowering driving means 50 disposed at the lower side, and can maintain the inserted state in the opening hole 11, So that they can be separated and replaced.

That is, the lifting and lowering plate 30 is lifted and lowered by the lifting and lowering driving means 50 disposed below the lower forming die 10, and is inserted to seal the opening hole 11. Further, the lifting plate 30 is lowered in accordance with the driving of the lifting / lowering drive means 50, so that the lifting plate 30 can be in a state accessible to the user and can be maintained and replaced by the user.

Various configurations and arrangements can be applied as long as the lifting / lowering drive means 50 can move the lifting plate 30 up and down. For example, as shown in FIGS. 1 to 5, the up / down driving means 50 includes a cylinder 53 for generating an up / down driving force, And a descending drive rod 51.

The cylinder 53 is fixed to the lower portion of the base plate, and the lifting and lowering driving rod 51 is connected to the lifting plate 30 through the base plate. Since the space between the base plate and the lower molding die 10 is a steam chamber space filled with steam entering from the outside, the lifting and lowering driving rod 51 passes through the base plate while keeping airtightness Of course.

As described above, the up-and-down driving rod 51 is connected to the up-down plate 30 so as to move up and down. That is, the ascending / descending plate 30 may be directly connected to the ascending / descending driving rod 51, or may be connected via the stopper plate 40 shown in the present invention.

The lower surface of the stopper plate 40 is connected to the elevating and lowering driving rod 51 and the upper surface thereof is in surface contact with the elevating and lowering plate 30 to be integrally formed. The stopper plate 40 has a larger area than the elevating and lowering plate 30 inserted into the opening hole 11.

Therefore, when the stopper plate 40 is raised in accordance with the driving of the up-and-down driving rod 51, the stopper plate 40 is moved in the state of being inserted into the opening hole 11, It is possible to maintain the contact state with the outer lower surface.

Thus, the ascending / descending plate 30 is connected to the ascending / descending driving rod 51 via the stopper plate 40, and can be moved up to a predetermined position through the stopper plate 40. However, the ascending / descending plate 30 may be directly connected to the ascending / descending driving rod 51 without interposing the stopper plate 40, and may be raised to a predetermined position according to the operation of the cylinder 53.

As described above, the ascending / descending plate 30 can close the opening 11 to maintain the inserted state in the opening hole. In this state, the raw material is injected into the molding space between the upper molding die and the lower molding die, and a molded product can be formed through the molding process. Therefore, if a predetermined shape is formed on the upper surface 30a of the ascending / descending plate 30, a predetermined mark can be formed on the molded product (denoted by reference numeral 1 in FIG. 6).

In the present invention, in order to form a predetermined mark on the surface of the molded product 1, the surface of the elevating plate 30, that is, the upper surface 30a, has an engraved portion 31 Is formed. That is, on the surface of the ascending / descending plate 30, an engraved portion 31 capable of engraving a mark on the surface of the molded article 1 is formed.

As a result, the engraving portion 31 is formed with an engraved shape capable of forming a mark to be engraved on the surface of the molded article 1. In the present invention, a mark "logo + KOMOTEC" is formed on the molded article 1, and the marking section 31 corresponds to "logo + KOMOTEC" which is a mark to be formed on the surface of the molded article 1 Is formed on the surface of the substrate.

The mark may be of various shapes to be imprinted on the molded article 1. [ Specifically, the mark according to the present invention means a symbol, a letter, a figure, a three-dimensional shape, or a combination thereof, and further means that it can be displayed by other visual methods.

As a result, since the engraved portion 31 is formed on the upper surface of the lifting plate 30, the surface of the molded product 1, which is finished through the molding process in the molding space, .

The above-described ascending / descending plate 30 is driven so as to be able to ascend and descend, and an engraved portion 31 having a predetermined marking is formed on the surface of the ascending and descending plate 30. Accordingly, various marks can be formed on the surface of the molded article 1. [

The mark may be formed on the surface of the molded product 1 in various forms depending on how the marking portion 31 is formed on the upper surface 30a of the elevating and lowering plate 30. [ That is, the engraved portion 31 may be directly formed on the surface of the lifting plate 30 (see FIG. 6) or protruded (convexly) from the surface of the lifting plate 30 (See Figs. 8 and 10), and may be recessed (concave) on the surface of the ascending / descending plate 30 (see Figs. 12 and 14).

The first shape of the engraved portion 31 formed on the surface of the ascending / descending plate 30 is as shown in FIG. The first engraved portion 31 shown in Fig. 6 is not formed convexly or concavely in the elevating plate 30, but is formed in a predetermined mark on the surface of the elevating plate 30.

Specifically, the first type imprinting unit 31 is formed by inserting the steam cap 35 into the elevating plate 30. That is, the stamping portion 31 is formed in the form of a stamp on the surface of the molded product, and the steam cap 35 is formed on the rising / falling plate 30 in a predetermined shape.

For example, the engraving portion 31 may have an engraved shape capable of forming "logo + KOMOTEC" on the surface of the molded article 1

+ Logo) is formed by arranging the steam cap 35 as shown in FIG.

The steam cap 35 may be inserted in such a manner that the steam cap 35 can be flush with the lifting plate 30 or may be inserted higher than the upper surface 30a of the lifting plate 30 . Even if the steam cap 35 is inserted and arranged so as to maintain the same plane as the elevating and lowering plate 30, the steam cap mark 7 is formed on the surface of the molded article 1 by the steam pressure in the molding process. Therefore, even in this case, a predetermined mark (logo + KOMOTEC) can be formed by the steam cap mark 7.

Since the imprinting section 31 is formed by inserting and placing the steam cap 35 on the lifting plate 30, the lifting plate 30 is provided with the steam cap 35 in the vertical direction It is a matter of course that the steam inflow hole 33 is formed. Accordingly, the steam in the steam chamber space can be introduced into the molding space through the steam inlet 35 and the steam inlet 35.

Fig. 7 shows a partial shape of the molded article 1 completed by the foamed foam forming die including the elevating plate 30 on which the stamping portion 31 of the first embodiment is formed. As shown in Fig. 7, the mark "logo + KOMOTEC" is engraved on the surface of the molded article 1. [

A plate corresponding portion 3 corresponding to the ascending and descending plate 30 is formed on the surface of the molded product 1 and a mark corresponding to the stamp portion 31 is formed on the plate corresponding portion 3, Forming portion 5 is formed.

Since the first type imprinting section 31 is formed by inserting and placing the steam cap 35 on the surface without protruding or sinking on the upper surface of the elevating plate 30, (5) is formed by a steam cap trail (7) formed by the steam cap (35).

The plate corresponding portion 3 may be flush with the surface of the molded article 1 or may be convex on the surface of the molded article 1 and may be formed concave on the surface of the molded article 1 It is possible.

The shape (flat, convex, concave) of the plate corresponding portion 3 can be changed according to the position where the lifting plate 30 is inserted into the opening hole 11. [ Specifically, when the upper surface 30a of the lifting plate 30 is flush with the bottom surface 10a of the lower molding die, the plate corresponding portion 3 is formed on the surface of the molded article 1 When the upper surface 30a of the ascending / descending plate 30 is positioned above the bottom surface 10a of the lower molding die, the plate corresponding portion 3 is formed on the same plane, When the upper surface 30a of the elevating and lowering plate 30 is located below the bottom surface 10a of the lower molding die 10, (Convex) on the surface of the substrate 1.

7 shows an example of the molded article 1 produced through the molding process in a state where the upper surface 30a of the lifting plate 30 shown in FIG. 6 is positioned below the inner bottom surface 10a of the lower molding die . Therefore, the plate corresponding portion 3 is formed to protrude (convex) from the surface of the molded article 1. [

Next, the second shape and the third shape of the engraving portion 31 formed on the surface of the ascending / descending plate 30 are as shown in Figs. 8 and 10. The engraved portions 31 of the second and third embodiments shown in Figs. 8 and 10 are formed to protrude (protrude) from the elevating plate 30.

That is, the engraved portion 31 of the second shape shown in Fig. 8 and the engraved portion 31 of the third shape shown in Fig. 10 are formed to protrude from the surface of the ascending / descending plate 30. 8 shows a state in which the engraved portion 31 is convexly formed and the steam cap 35 is inserted only in the engraved portion 31, The upward / downward plate 30 shown in the drawing shows that the engraved portion 31 is formed in a convex shape and the steam cap 35 is inserted in a portion except the engraved portion 35.

Specifically, the imprinting portion 31 according to the present invention is protruded from the surface of the ascending / descending plate 30, and the steam cap 35 is inserted only in the protruding engraved portion 31 (see FIG. 8) Or only the elevating plate 30 except for the engraving portion 31 (see FIG. 10).

For example, the engraved portions 31 of the second and third forms shown in Figs. 8 and 10 are formed in an engraved shape ("engraving") capable of forming "logo + KOMOTEC"

+ Logo) is formed to protrude (convex) on the surface of the ascending / descending plate 30 as shown in Figs. 8 and 10.

8 shows that the steam cap 35 is inserted only in the convexly formed engraved portion 31. The upward and downward plate 30 shown in FIG. Illustrates that the steam cap 35 is inserted and disposed only in a portion except the engraved portion 31. [

8 can be obtained by directly inserting the steam cap 35 into the engraved portion 31 and inscribing the engraved shape formed in the engraved portion 31

The steam lifting plate 30 shown in Fig. 10 is arranged to insert the steam cap 35 around the engraved portion 31 and to engrave the engraved portion 31 (

+ Logo) can be further emphasized.

Since the upward / downward plate 30 shown in FIG. 8 is formed by inserting and arranging only the steam cap 35 on the engraved portion 31, the upward / downward plate 30 and the engraved portion 31 are provided with steam It is a matter of course that the steam inflow hole 33 is formed in the vertical direction corresponding to the cap 35. Accordingly, the steam in the steam chamber space can be introduced into the molding space through the steam inlet 35 and the steam inlet 35.

Since the upward and downward movement plate 30 shown in FIG. 10 is formed by inserting the steam cap 35 into the upward and downward plates except the engraved portion 31, It is a matter of course that the steam inflow hole 33 is formed in the vertical direction corresponding to the cap 35. Accordingly, the steam in the steam chamber space can be introduced into the molding space through the steam inlet 35 and the steam inlet 35.

By means of the lifting plate 30 shown in FIGS. 8 and 10, the molded article 1 can be stamped in various forms. That is, depending on the position where the ascending / descending plate 30 is disposed in the opening hole 11 formed in the lower molding die 1, the molded product 1 has different shapes.

The elevating plate 30 is held in the open hole 11 while the elevating plate upper surface 30a is positioned above the bottom surface 10a of the lower forming die, When the molded product 1 is completed through the molding process, the plate corresponding part stamped corresponding to the ascending and descending plate 30 is recessed from the surface of the molded product, and corresponds to the protruding stamped part 31 Is formed by being recessed in the plate corresponding portion in which the recess is formed.

As a result, when the upper and lower lifting plate upper surfaces 30a are positioned above the bottom surface 10a of the lower forming mold, the molded product 1 is completed through the molding process, In the state that the plate is depressed again, there is a disadvantage in that it can not be emphasized somewhat visually.

On the other hand, the elevating and lowering plate 30 is kept inserted into the opening 11, and the elevating and lowering plate upper surface 30a is positioned on the same plane as the bottom surface 10a of the lower forming mold Or the lower part of the lower molding die is positioned below the bottom surface 10a of the molded product to complete the molded product 1 through the molding process, the plate corresponding part, which is stamped corresponding to the lifting plate 30, Or a protruding portion formed in the plate corresponding portion, and a mark forming portion corresponding to the protruding formed portion 31 is formed by being recessed in the same plane or protruding plate corresponding portion.

As a result, the upper and lower lifting plate upper surfaces 30a are positioned on the same plane as the bottom surface 10a of the lower forming mold or are positioned lower than the bottom surface 10a of the lower forming mold, (1) is completed, since the mark formation portions corresponding to the mark are formed by being recessed at the plate corresponding portions in the same plane or protruded state, there is no problem in that they are visually highlighted (there is sufficient visual incidence) It is possible to solve the cosmetic problem due to the double protrusion (the protruding portion corresponding to the protruding plate protrudes again), the problem of the transfer of the molded article and the problem of the lamination.

In summary, with respect to the elevating and lowering plate 30 shown in FIGS. 8 and 10, the forming process is performed in a state where the elevating and lowering plate upper surface 30a is positioned above the bottom surface 10a of the lower forming mold Lowering plate upper surface 30a is positioned on the same plane as the inner bottom surface 10a of the lower forming mold or lower than the inner bottom surface 10a of the lower forming mold 10a, The molded product 1 can be completed through the molding process in a state where it is positioned on the protruding plate corresponding to the protruding plate corresponding part, The upper and lower lifting plate upper surfaces 30a are positioned on the same plane as the inner bottom surface 10a of the lower forming die, It is more preferable to complete the molded product 1 through a molding process in a state of being positioned below the bottom surface 10a of the lower molding die.

FIG. 9 illustrates a state in which the molded product 1 is completed through the molding process in a state where the up-and-down plate upper surface 30a shown in FIG. 8 is positioned below the bottom surface 10a of the lower molding die.

Specifically, as shown in FIG. 9, the elevating and lowering plate 30 shown in FIG. 8, that is, the elevating plate 30 in which the steam cap 35 is inserted into the protruding engraving portion 31, When the molded product 1 is manufactured using the foamed foam forming mold, the plate corresponding portion 3 is formed on the surface of the molded product 1 so as to protrude (convexly), and the surface of the protruded plate corresponding portion 3 (Concave) to form the mark formation portion 5. In addition, a steam cap mark 7 corresponding to the steam cap 35 is formed in the mark formation unit 5.

In such a molded product 1, since the mark formation portion 5 is formed on the protruded plate corresponding portion 3 without being protruded, the mark protruding problem can be fundamentally solved. Further, since the steam cap marks 7 are formed on the mark formation unit 5, the mark displayed on the mark formation unit can be further highlighted.

FIG. 11 illustrates a state in which the molded product 1 is completed through a molding process in a state where the up-and-down plate upper surface 30a shown in FIG. 10 is positioned lower than the bottom surface 10a of the lower molding die.

Specifically, as shown in FIG. 11, the steam cap 35 is inserted into the rising and falling plate 30, that is, the rising and falling plate, which is a portion excluding the projected engraved portion 31, When the molded product 1 is manufactured using the foamed foam forming mold including the lowering plate 30, the plate corresponding portion 3 is formed on the surface of the molded product 1 so as to protrude (convex) (Recessed) on the surface of the plate-corresponding portion 3 to form the mark formation portion 5. [ A steam cap mark 7 corresponding to the steam cap 35 is formed on the ascending / descending plate 30 around the mark forming unit 5.

In such a molded product 1, since the mark formation portion 5 is formed on the protruded plate corresponding portion 3 without being protruded, the mark protruding problem can be fundamentally solved. Further, since the steam cap marks 7 are formed along the periphery of the mark formation unit 5, the marks displayed by the mark formation unit can be further highlighted.

Next, the fourth and fifth embodiments of the engraving portion 31 formed on the surface of the ascending / descending plate 30 are as shown in Figs. 12 and 14. Fig. The engraved portions 31 of the fourth and fifth embodiments shown in Figs. 10 and 12 are formed so as to be recessed (recessed) in the lifting plate 30.

That is, the engraved portion 31 of the fourth embodiment shown in Fig. 12 and the engraved portion 31 of the fifth embodiment shown in Fig. 14 are recessed (recessed) from the surface of the ascending / descending plate 30. The elevating and lowering plate 30 shown in Fig. 12 shows a state in which the engaging portion 31 is formed concavely (recessed), and the steam cap 35 is inserted only in the engaging portion 31 , The elevating and lowering plate 30 shown in Fig. 14 is formed such that the engraved portion 31 is recessed (recessed), and the steam cap 35 is inserted and disposed in a portion except the engraved portion 35 .

Specifically, the imprinting portion 31 according to the present invention is recessed from the surface of the ascending / descending plate 30, and the steam cap 35 is inserted only in the recessed portion 31 formed by the depression (see FIG. 12) Or only the elevating plate 30 except for the engraving portion 31 (see FIG. 14).

For example, the engraved portions 31 of the fourth and fifth forms shown in Figs. 12 and 14 are formed in an engraved shape capable of forming "logo + KOMOTEC" on the surface of the molded article 1

+ Logo) is recessed (recessed) on the surface of the lifting plate 30 as shown in FIG. 12 and FIG.

Accordingly, the steam in the steam chamber space can be introduced into the molding space through the steam inlet 35 and the steam inlet 35.

The molded article 1 can be stamped in various forms by the lifting plate 30 shown in FIGS. 12 and 14. That is, depending on the position where the ascending / descending plate 30 is disposed in the opening hole 11 formed in the lower molding die 1, the molded product 1 has different shapes.

The elevating plate 30 is held in the open hole 11 while the elevating plate upper surface 30a is positioned below the bottom surface 10a of the lower forming die, When the molded product 1 is completed through the molding process, the plate corresponding portion stamped corresponding to the ascending / descending plate 30 is formed protruding from the surface of the molded product, and corresponds to the engraved portion 31 Is formed by protruding from the plate-corresponding portion to be protruded.

As a result, when the molded article 1 is completed through the molding process in a state where the upward / downward plate upper surface 30a is positioned below the bottom surface 10a of the lower molding die, the mark formation portion corresponding to the mark is protruded The plate can be repelled at the plate corresponding portion in the state of being in a state of being in contact with the surface of the molded article, which may cause problems in the conveyance and loading of the molded article, and may have problems in appearance and inadequate use.

On the other hand, the elevating and lowering plate 30 is kept inserted into the opening 11, and the elevating and lowering plate upper surface 30a is positioned on the same plane as the bottom surface 10a of the lower forming mold And the plate corresponding part stamped in correspondence with the elevating and lowering plate 30 is formed on the surface of the molded article when the molded product 1 is completed through the molding process in a state of being positioned above the bottom surface 10a of the lower forming mold, Or a recess corresponding to the plate corresponding portion, and a mark forming portion corresponding to the engraved portion 31 is formed protruding from the plate corresponding portion formed in the same plane or recessed shape.

As a result, the upper and lower lifting plate upper surfaces 30a are positioned on the same plane as the bottom surface 10a of the lower shaping mold or above the bottom surface 10a of the lower shaping mold, (1) is completed, since the mark formation portions corresponding to the mark are formed protruding from the plate corresponding portions in the same plane or recessed state, there is no problem in that they are visually remarkable (there is sufficient visual incidence) It is possible to solve the cosmetic problem due to the double protrusion (the protruding portion corresponding to the protruding plate protrudes again), the problem of the transfer of the molded article and the problem of the lamination.

With respect to the elevating and lowering plate 30 shown in FIGS. 12 and 14, the molding process is performed in a state where the elevating and lowering plate upper surface 30a is positioned lower than the inner bottom surface 10a of the lower forming mold Lowering plate upper surface 30a is positioned on the same plane as the inner bottom surface 10a of the lower forming mold or is positioned above the bottom surface 10a of the lower forming mold, The molded product 1 can be completed through the molding process in a state where it is positioned on the protruding plate corresponding to the protruding plate corresponding part, The upper and lower lifting plate upper surfaces 30a are positioned on the same plane as the inner bottom surface 10a of the lower forming mold, Through the molding process in a state located above the surface (10a) of the lower mold for molding the inner bottom, it is more preferred to finish the molded product (1).

FIG. 13 illustrates a state in which the molded product 1 is completed through a molding process in a state where the up-and-down plate upper surface 30a shown in FIG. 12 is positioned above the bottom surface 10a of the lower molding die.

Specifically, as shown in FIG. 13, the lifting plate 30 shown in FIG. 12, that is, the lifting plate 30 in which the steam cap 35 is inserted into the depressed engaging portion 31 When the molded product 1 is manufactured using the foamed foam forming mold, the plate corresponding portion 3 is formed on the surface of the molded product 1 so as to be recessed (recessed), and the surface of the plate corresponding portion 3 (Convexly) so as to form the mark formation portion 5. In addition, a steam cap mark 7 corresponding to the steam cap 35 is formed in the mark formation unit 5.

Such a molded article 1 is sufficiently projected on the plate-corresponding portion 3 formed with the depression so that the mark formation portion 5 is protruded without being recessed. Further, since the steam cap marks 7 are formed on the mark formation unit 5, the mark displayed on the mark formation unit can be further highlighted.

FIG. 15 illustrates a state in which the molded product 1 is completed through a molding process in a state where the up-and-down plate upper surface 30a shown in FIG. 14 is positioned above the bottom surface 10a of the lower molding die.

More specifically, as shown in FIG. 15, the steam cap 35 is inserted into the rising / falling plate 30, that is, a portion of the rising / falling plate except for the recessed depressions 31, When the molded article 1 is manufactured using the foamed foam forming die including the lowering plate 30, the plate corresponding portion 3 is formed on the surface of the molded article 1 so as to be recessed (recessed) (Convexly) protruding from the surface of the plate corresponding portion 3 to form the mark forming portion 5. [ A steam cap mark 7 corresponding to the steam cap 35 is formed on the ascending / descending plate 30 around the mark forming unit 5.

Since the molded article 1 is protruded without being depressed on the depressed plate corresponding portion 3, the embossing force is sufficient and the problem of double sticking can be fundamentally solved. Further, since the steam cap marks 7 are formed along the periphery of the mark formation unit 5, the marks displayed by the mark formation unit can be further highlighted.

The foamed foam forming mold 100 described above enables various marks to be impressed on the surface of the molded article 1 in various forms. 16 shows that the molded article 1 is stamped with a mark. More specifically, the mark forming portion 5 is formed on the plate corresponding portion 3 and the steam cap mark 7 is formed on the mark forming portion 5, have.

On the other hand, Fig. 17 shows a molded article in which a mark is stamped on the molded article 1, and parts other than the plate corresponding parts, that is, the other part of the molded article, are formed with the steam cap marks 7. That is, only the engaging portion 31 is formed on the upper surface of the ascending / descending plate 30 for manufacturing the molded article shown in Fig. 17, and the steam cap 35 is not formed on the engaging portion or the ascending / descending plate. Instead, the steam cap is formed on the bottom surface (a portion other than the opening hole) of the lower forming die 10. Therefore, the molded article shown in Fig. 17 can also be manufactured.
