- thermoplastic resin products of various colors and designs can be expressed on fabric or hot melt surfaces without sewing.
- the present invention does not insert a pre-weighed thermoplastic resin material into the mold to perform cold forming, but if the thermoplastic resin material is completely filled in a specific specific cavity space inside the mold in the molten state, the unnecessary material is removed, followed by cold forming.

- FIG. 33 to 40 are schematic diagrams for explaining some of the processes in FIG. 32.
- the present invention includes preparing a mold (S110), filling a thermoplastic synthetic resin material into the mold (S132 and S136), heating the mold (S140), opening a mold (S150), and a material. Removing some of the steps (S170), placing any one selected from the fabric or hot melt (S180), crosslinking and cold forming the molding material in contact with any one selected from the fabric or hot melt ( S190) is characterized by including.
- the inner space of the mold is a cavity filled with thermoplastic synthetic resin materials, which will be described later, and is preferably formed in an intaglio.
- the cavity of the mold formed according to the present invention may be made of a single shape cavity or a plurality of cavities according to the number thereof, and the cavity space may be formed in a planar or three-dimensional shape or a combination of both depending on the structure thereof. In the form of a common space may be made.
- die which is provided with the cavity in which the internal space is engraved in three-dimensional shape is different from the structure of the conventional metal mold
- the mold core and the inner surface are provided with a cavity corresponding to the outer surface shape except the intaglio cavity in the mold core, so that the configuration of the combination mold including the mold body coupled to the mold core may be assumed.
- the plurality of cavities of the mold may be connected to each other, or at least one selected from the plurality of cavities may be formed separately from the remaining cavities, or all of the plurality of cavities may be formed from each other. It may be formed separately.
- the cavity of the mold having various shapes is preferably made identical to the overall appearance of the final thermoplastic synthetic resin product.
- the present invention does not exclude the case where the cavity structure of the mold consists of a first cavity in which the fabric is placed and a second cavity formed intaglio on the surface of the first cavity to fill the thermoplastic resin material.
- 2 shows an example of a mold 1 in which a plurality of individual cavities 2 are formed therein.
- thermoplastic synthetic resin material 10 made of any color and material is filled in the cavity of the mold as shown in FIG.
- the volume (amount) of the material to be filled in the cavity is preferably made larger than the cavity volume of the mold as shown in the figure.
- a method of filling a thermoplastic synthetic resin material into a cavity of a mold may assume two things as follows. One of them is to place the thermoplastic synthetic resin material directly in the cavity with the mold open (S132), and the material used in this case is preferably made of a solid phase. When the material is made of a solid phase, the shape may be formed to correspond to the shape of the cavity.
- the other is to fill the thermoplastic synthetic resin material in the cavity by using a device such as a material injector of the injection molding machine in a sealed state (S136).
- a device such as a material injector of the injection molding machine in a sealed state (S136).
- the solid phase material is supplied to the cavity space through the material injection hole and the material injection path of the closed mold in the state of being softened by low temperature heating by the heating means mounted inside the apparatus.
- the amount of the thermoplastic synthetic resin material placed directly in the cavity inside the mold or supplied through the apparatus may be larger than the volume of the cavity and can be arbitrarily determined according to the product. This is largely distinguished from the conventional method in which the internal cavity volume of each color mold and the amount of material to be filled must be exactly matched without even a precise deviation range, especially in the integrated cold forming of multi-color products.
- thermoplastic synthetic resin material according to the present invention (herein, the thermoplastic synthetic resin material is a concept including both the first thermoplastic synthetic resin material and the second thermoplastic synthetic resin material to be described later) may be selected from any materials commonly used in the related art. It can be obvious.
- thermoplastic synthetic resin material When the thermoplastic synthetic resin material is filled in the inner space of the mold, the mold is sealed in such a manner that the filled material does not flow out of the mold and then the mold is heated under a predetermined pressure (S140).
- S140 a predetermined pressure
- the thermoplastic resin material melted by the heat is first filled in the cavity of the mold located in the lower part of the mold cavity space, and the remaining oversupply molten material is a space other than the cavity space. It is located at the periphery and surface of the phosphorus cavity. In other words, the surplus of the material supplied in excess of the volume of the cavity space leaves the cavity space boundary of the mold.
