JP-A-10-75713

  Here, since the mold for molding chocolate in the above-mentioned conventional example has a decorative shape on the bottom of the bottom of one recess, only one type of chocolate can be poured, and the decorative part and the chocolate body part There arises a problem that it cannot be formed with chocolates of different colors. In other words, it has been difficult to devise such as making the chocolate decoration part stand out. Such a problem may also occur when a molded product using sugar confectionery or other materials is molded.

  Further, in Patent Document 1, as a method for producing a mold for molding, it is disclosed that a thermoplastic synthetic resin is molded by compression molding, vacuum molding, compressed air generation, or the like. A mold with a shape is required. Such molds are not only time consuming to manufacture, but also very expensive and difficult to produce many types. In other words, when a molded product such as a chocolate having a single shape is manufactured, it is first costly to produce a mold. Therefore, it is not profitable unless the molded product such as a chocolate is mass-produced. In other words, it was difficult in terms of cost to manufacture a small number of molded articles such as chocolates having surface decorations such as original letters according to individual needs.

  For this reason, the object of the present invention is to provide a molding die capable of improving the inconveniences of the above-described conventional examples, and in particular, capable of producing a molded product having a specific decoration on the surface at a low cost. To do.

Therefore, the molding die according to the present invention is
A bottom mold formed by engraving a plate-shaped member with a concave portion to be a surface decoration of a molded product,
A frame mold having a shape corresponding to the outer shape of the molded product, and the frame is arranged on the bottom mold so as to surround the recess;
It is characterized by having.

The bottom mold has a plurality of recesses corresponding to the surface decoration for one molded product so as to correspond to a plurality of molded products,
The frame mold has a plurality of frame portions arranged so as to surround each of the concave portions corresponding to the plurality of concave portions,
It is characterized by that.

  Further, the bottom mold is characterized in that a concave portion is carved into the plate-like member by laser engraving. At this time, the engraving depth of the recess formed in the bottom mold is preferably 0.15 mm to 0.5 mm, and more preferably 0.25 mm to 0.35 mm.

  Furthermore, the frame mold may be formed by overlapping a plurality of plate-like members on which frame portions having the same shape are formed in advance.

The present invention also provides a method for producing a molded product using the molding die described above,
A decorative material filling step for filling the concave portion formed in the bottom mold with the decorative material;
A main body material filling step of placing and fixing the frame mold on the bottom mold so as to surround the recess filled with the decoration material with the frame mold frame section, and filling the frame section with the main body material;
A mold release step of solidifying the material filled in each mold and releasing the solidified molding;
It is characterized by having.

  In the above method, when the frame mold is placed in the main body material filling step, or before that, a plurality of plate-like members having the same shape of the frame portion are overlapped to form the frame mold. It is characterized by forming.

  According to the above invention, first, a decorative material (for example, a material having a color different from the color of the molded body) is poured into the bottom mold to fill the concave portion (decorative material filling step). At this time, the material protruding from the recess is removed with a spatula or the like. Subsequently, the frame mold is placed on the bottom mold so as to surround the concave portion filled with the decoration material with the frame section, and the periphery is fixed and integrated with a tape or the like so as not to separate them. And the material for main bodies used as a molding main body is poured into the frame part of this frame type etc., and is filled (main body material filling process). Thereafter, the material filled in each mold is solidified and released (release process). As a result, the surface decoration can be molded three-dimensionally and with a different type of material from the main body portion, and the decorative portions such as letters and patterns can be conspicuous.

  In addition, since the bottom mold recess is formed by engraving the plate-like member with laser engraving, it is not necessary to manufacture a mold for molding the bottom mold, and it is a unique decoration at a low cost. Can be produced. At this time, it is desirable to form the recesses with a depth of 0.15 mm to 0.5 mm, particularly 0.25 mm to 0.35 mm. Then, since a decoration part can be shape | molded more reliably and it can be made to mold | release easily after a decoration part solidifies, the molding which has a surface decoration can be manufactured easily. Furthermore, since the depth of the recess formed by engraving by laser engraving or the like is not too deep, the engraving work for the plate-like member, that is, the bottom mold can be quickly manufactured, and the manufacturing cost of the bottom mold is further increased. Reduction can be achieved.

  In addition, a decorative concave portion corresponding to a plurality of moldings is formed on the bottom mold, and a plurality of frame portions are also formed on the frame mold correspondingly, thereby allowing a plurality of the same type or different types to be simultaneously formed. The molded product can be molded, and the manufacturing cost of the molded product can be reduced.

  Furthermore, by forming a frame mold by overlapping a plurality of plate-like members having the same frame portion, the thickness of a single plate-like member serving as the frame mold can be reduced, and by laser cutting or the like The formation process of the frame part can be shortened, and the manufacturing cost of the frame mold can be reduced.

  Since this invention is comprised and functions as mentioned above, according to this, molded objects, such as chocolate which has decoration parts, such as a character and a pattern, can be manufactured at low cost. Therefore, it has an unprecedented excellent effect that a molded product having a surface decoration such as a unique character according to individual needs can be manufactured at a low cost even with a small number.

  The molding die according to the present invention is characterized by having a bottom die in which a decorative concave portion is engraved and a frame die. In the following examples, chocolate will be described as an example of the material to be molded. However, the mold for molding according to the present invention and the method for producing a molded product using this mold can also be used when a candy, pudding, clay or the like is packed in a mold and molded. It is not limited to what you did.

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view showing the shape of the bottom mold, and FIG. 2 is an explanatory view showing the state of the bottom mold during manufacture. FIG. 3 is a plan view showing a frame shape. FIG. 4 is a plan view showing a state when the bottom mold and the frame mold are overlapped. FIG. 5 is a flowchart illustrating a method for manufacturing chocolate, and FIG. 6 is a diagram illustrating an example of manufactured chocolate.

[Constitution]
As shown in FIG. 4 to be described later, the chocolate molding die 10 in this embodiment is composed of a bottom die 1 and a frame die 2 which are plate-like members that are superposed on each other. Hereinafter, each type | mold 1, 2 is explained in full detail.

  The bottom plate 1 is, for example, an acrylic plate having a thickness of several mm, and a concave portion 11 having a shape serving as a chocolate surface decoration is formed on the surface thereof. Here, the recessed part 11 is a character, a picture, a pattern, etc., and is an original thing set by the client who requested manufacture. In the example of FIG. 1, a concave portion 11 (outlined character portion) of a predetermined character is formed.

  Here, FIG. 2 shows a configuration of the laser processing machine 3 for forming the recess 11 in the bottom mold 1 and a state when the recess 11 is formed. The laser beam machine 3 shown in this figure includes a laser irradiation device 31 that irradiates the surface of the bottom mold 1, which is an acrylic plate placed on a work table G, with a laser beam 31 a for engraving, and a laser irradiation device 31. And a controller 33 for controlling the laser irradiation position and the irradiation output. The laser irradiation device 31 outputs a predetermined beam system (for example, 30 μm) and a laser beam having a predetermined intensity in accordance with a control command from the controller 33. The controller 33 stores data representing a decorative shape in advance, and the controller 33 forms the recess 11 by engraving the shape and depth according to the decorative shape data by laser engraving. Thus, the operation of the laser torch 31 and the output value and output time of the laser beam are controlled. By doing in this way, in the example shown in FIG. 1, the character used as a decoration is formed in the depth of about 0.3 mm from the surface of an acrylic board. In addition, although the depth of the recessed part 11 is arbitrary, when it is too shallow (for example, about 0.1 mm), it will be removed excessively when removing extra chocolate after pouring decorative chocolate so that it may mention later. From experience, it has been found that there is a problem that mold release becomes difficult if the depth is too deep (for example, about 1 mm). Therefore, it may be set to be formed around 0.3 mm described above (for example, 0.15 mm to 0.5 mm, particularly 0.25 mm to 0.35 mm). However, the processing of the recess 11 is not limited to processing by laser engraving.

  The bottom mold 1 is formed with a plurality of recesses indicated by reference numeral 12 corresponding to the surface decoration for one chocolate so as to correspond to a plurality of chocolates. At this time, the plurality of recesses may have a decorative shape such as the same type of character, or may be a different type of decoration. For example, when manufacturing a plurality of chocolates decorated with a specific character as a souvenir, a plurality of the same type of character decoration may be formed, and the bottom mold 1 may be used a plurality of times. In the case of manufacturing a single product, it is formed on one acrylic plate together with other character decorations, and such a mold may be disposable.

  Next, the frame mold 2 will be described with reference to FIG. The frame mold 2 is formed of an acrylic plate (plate member) having a predetermined thickness like the bottom mold 1, and the outer peripheral shape is the same as the bottom plate 1. And this frame type | mold 2 is a type | mold which forms the external shape of chocolate, Comprising: The frame part 21 which is a hole of the shape corresponding to the external shape of the chocolate which penetrates an acrylic board in thickness direction is formed. Each of these frame portions 21 is formed in a size capable of enclosing each of the recesses 11 that are decorations formed on the above-described bottom mold 1, and as will be described later, the frame mold 2 is placed on the bottom mold. When arranged, each frame portion 21 is formed on each recess 11. In addition, although a present Example illustrates the case where the external shape of chocolate, ie, the shape of the frame part 21, is a substantially rectangular shape, it is not limited to this shape. Moreover, although all the shapes of the frame part 21 are the same, they may differ.

  Next, the relationship between the two types 1 and 2 will be described. As shown in FIG. 4, when the chocolate is actually molded, the frame mold 2 is placed on the bottom mold 1 and superposed to form a chocolate molding mold 10. At this time, the bottom plate 1 and the frame mold 2 are integrated by fixing the outer peripheral portion with a tape so as not to be separated from each other. At this time, a plurality of the frame molds 2 in which the frame portions 21 having the same shape are formed may be overlapped and fixed. However, it is necessary to perform alignment so that the shape of each frame portion 21 continuous in the thickness direction of the frame mold 2 matches. Thereby, the thickness of the chocolate main body to shape | mold can be adjusted by adjusting the number of frames 2. For example, an acrylic plate having a thickness of about 2 mm to 4 mm may be used for one frame mold 2. Then, the cutting work of the frame portion 21 becomes easy, the processing time can be speeded up and the manufacturing cost can be reduced, and a thick chocolate is formed by overlapping a plurality of pieces as described above. It is possible to deal with cases.

[Operation]
Then, with reference to the flowchart of FIG. 5, the chocolate manufacturing method using the said mold for chocolate shaping | molding is demonstrated.

  First, as shown in FIG. 2, a plurality of recesses 11 are formed on the acrylic plate by laser engraving, and the bottom mold 1 is molded. And this bottom type | mold 1 is arrange | positioned in the place which manufactures chocolate (step S1). Subsequently, white chocolate (not limited to white chocolate), which is a decorative chocolate, is poured onto the bottom mold 1, that is, a plurality of recesses 11, and filled in the recesses 11 (step S <b> 2). And the white chocolate which protruded from this recessed part 11 is removed with a spatula etc. (step S3). The above is the decorative material filling step.

  Subsequently, as shown in FIG. 4, the frame mold 2 is placed on the bottom mold 1 so as to surround the concave portion 11 filled with white chocolate with the frame section 21, and the periphery is fixed with a tape or the like (step S4). ). At this time, a plurality of frame molds 2 are arranged in accordance with the thickness of the chocolate to be manufactured. Note that the frame mold 2 may be prepared in advance by stacking a plurality of sheets. Then, after a certain period of time has passed, the white chocolate has hardened, or immediately before it is hardened, black chocolate that becomes the chocolate body respectively on the plurality of frame portions 21 of the frame 2 (however, it is not limited to black chocolate). (Step S5). The above is the main material filling process.

  Then, it waits until black chocolate solidifies or cools (step S6). Then, after completely solidifying, the chocolate is released (release process). Thereby, chocolate 4 (molded product) as shown in FIG. 6 can be molded, and in particular, a decorative portion 42 that is a character decoration is decorated on the surface of the chocolate main body portion 41 of black chocolate that is a main body material. It will be formed three-dimensionally with the material white chocolate. Therefore, decorative parts such as characters and patterns can be made conspicuous.

  And as mentioned above, while using a low-cost member such as an acrylic plate for the mold, and forming a concave portion to be a decorative portion by laser engraving, a chocolate having a unique decoration is manufactured at a low cost. be able to. For example, chocolate that is a one-piece product decorated with a specific message, chocolate that is manufactured as a souvenir with a specific decoration and is manufactured in units of several tens, etc. can be manufactured at low cost. Specifically, it can be used when manufacturing chocolate to be sent to a specific person on Valentine's Day or chocolate that is given to a layperson as a wedding gift.
