Description

Technical Field

[0001] This utility model belongs to the field of toy manufacturing technology, and in particular relates to a doll facial structure manufactured by molding process, which is suitable for the structural design and mass production of plush toy facial components with high requirements for facial softness, safety and stability. Background Technology

[0002] Currently, the facial features of fabric dolls are mostly expressed through sewing, epoxy resin, or the insertion of plastic parts. This type of structure has the following problems: The parts are prone to loosening or falling off, posing a risk of accidental ingestion by children. Poor assembly consistency, with manual assembly resulting in significant positional deviations of symmetrical components; The inconsistent appearance and stiff texture make it difficult to meet the requirements of softness, safety, and aesthetics. Therefore, there is a need for a solution that provides a monolithically molded facial component with a robust structure, good consistency, and softness. Summary of the Invention

[0003] The facial structure of this doll includes a face skin component, a supporting component, and black eyeball patches, characterized by: The face panel component (1) is made of a face panel fabric layer (2) and a foam layer (3) bonded together with PUR hot melt adhesive. The face panel foam has a thickness of 2 mm and a density of 30±1 kg / m³, and has compression resilience. The support component (20) includes a four-layer structure consisting of a skin-friendly fabric layer (21), a first foam layer (22), a bulging foam layer (23), and a non-elastic shaping yarn layer (24). The top of the support component is provided with a positioning bulge structure for the left eyeball, the right eyeball, and the nose, as well as two positioning grooves. The black eyeball patch (40) is made of PET material and is fixed in the positioning groove of the support component.

[0004] Further technical solutions: The faceplate component is prepared by a molding process, with the upper and lower mold temperatures at 180°C, the pressure at 3 PSI, and the holding time at 50 seconds. The cutting of the face skin components includes punching and cutting along the die line, punching along the folding mark line, and folding inward 180 degrees to form the eyelid structure; The surface components and supporting components are bonded together by spraying PUR hot melt environmentally friendly adhesive, resulting in a uniform and firm bond.

[0005] Process parameter description: The molding process for the faceplate components adopts hot pressing, with the upper and lower mold temperatures at 180℃, hot pressing pressure at 3 PSI, and holding pressure for 50 seconds to ensure the molding effect of the three-dimensional structure. The inner lining foam of the face panel component is 2 mm thick and has a density of 30±1 kg / m³, exhibiting excellent compression resilience. The bonding between the surface components and the supporting components uses PUR hot melt environmentally friendly adhesive, which is applied evenly using hot melt adhesive coating equipment to ensure a strong and environmentally friendly bond.

Detailed Implementation

[0007] Referring to Figures 1 to 6, and in conjunction with the doll facial structure and manufacturing method provided by this utility model, the specific implementation steps are as follows: According to the structure shown in Figure 2, each component is molded and shaped separately, and then assembled by alignment and bonding. A leather fabric layer 2 and a foam layer 3 with a thickness of 2 mm and a density of 30±1 kg / m³ are selected and bonded together using a PUR hot melt adhesive spraying device to form a composite leather component 1. After printing the composite fabric, place it on the cutting table and cut out the outer skin components according to the mold outline drawing; The cut-out dough components are placed into the mold and molded. The molding parameters are: upper and lower mold temperature 180℃, pressure 3 PSI, and holding time 50 seconds, forming a three-dimensional structure with eyelids, nose protrusions, and mouth grooves. Along the edge mark 11 of the skin component, the outer extension is punched and cut into individual parts; As shown in Figure 4, the lower edge of the eyelid is cut along the cutting line 4a, and the eyelid is folded inward by 180° according to the folding mark line 4b to form a wrapping structure; PUR environmentally friendly hot melt adhesive is evenly sprayed onto the adhesive spraying area 13 on the back of the face skin using a hot melt adhesive coating equipment for subsequent bonding with the supporting structure; The support structure 20 is composed of a skin-friendly fabric layer 21, a first foam layer 22, a bulging foam layer 23 and a non-elastic shaping yarn layer 24 stacked in sequence, and molded to form a bulging structure for the nose and left and right eyeballs. The top of the bulge structure is provided with a first positioning groove 25 and a second positioning groove 26 for attaching and fixing the first black eye patch 41 and the second black eye patch 42 made of PET material; The faceplate components are combined with the supporting structure through molding and adhesive bonding, and non-elastic shaping yarn is used to reduce the risk of deformation and stretching during filling or use. After final inspection, standardized and highly consistent doll-molded facial components were obtained. The molding process parameters, foam thickness and density, and adhesive type described above are preferred embodiments. In practical applications, adjustments can be made based on specific equipment, materials, and process requirements. All equivalent improvements within the scope of this utility model's technical solution are protected by this utility model.

[0008] Beneficial effects The facial components are integrally molded, ensuring good structural stability and effectively preventing parts from falling off; Ensure facial symmetry and consistency in appearance; The material is soft to the touch, enhancing product safety; It has low manufacturing costs and is suitable for large-scale mass production.
