DETAILED DESCRIPTION

As shown in FIG1 , a multi-color car floor mat comprises a floor mat body 1, the upper surface of the floor mat body 1 has a concave-convex pattern 11, an insert 2 is further provided on the upper surface of the floor mat body 1 at the concave-convex pattern 11, the floor mat body 1 and the insert 2 are in different colors, the concave-convex pattern 11 and the insert 2 are combined to form a decorative pattern; an identification piece 3 is further provided on the upper surface of the floor mat body 1 near the edge; the floor mat body 1, the insert 2 and the identification piece 3 are all made of TPE material; the insert and the identification piece are thermally fused into one by in-mold injection molding.

As shown in Fig. 2-3, a multi-color automobile floor mat injection mold includes a lower mold body 5 and an upper mold body 6, the lower mold body 5 has a mold cavity 51, the shape of the mold cavity 51 matches the lower surface of the foot pad body 1, the inner wall and the bottom surface of the mold cavity 51 are provided with concave and convex patterns, the upper mold body 6 has a mold core 61, the surface of the mold core 61 is also provided with a concave and convex pattern, the shape of the mold core 61 matches the upper surface of the foot pad body 1, the concave portion of the mold cavity 51 corresponds to the convex portion of the mold core 61, the convex side of the mold cavity 51 corresponds to the concave portion of the mold core 61, and a positioning groove 62 for the insert is also opened on the surface of the mold core 61, and the shape of the positioning groove 62 matches the shape of the insert 2.

The bottom surface of the mold cavity 51 is provided with a marking positioning groove 52 near the edge, and the mold core 61 is provided with a flat portion 63 corresponding to the marking positioning groove. The marking 3 of the foot pad is placed in the marking positioning groove 52. When the upper and lower molds are closed, the top surface of the marking part 3 touches the flat portion 63.

During production, several prefabricated inserts 2 are respectively installed into the fixing grooves 62 corresponding to the inserts on the core surface of the upper mold body 6, and then the identification part 3 is installed into the identification positioning groove 52 in the mold cavity of the lower mold body 5. Then the upper mold body 6 and the lower mold body 5 are closed for injection molding, and the molten TPE raw material enters and fills the gap between the cavity and the core. When the surfaces of the inserts 2 and the identification part 3 come into contact with the high-temperature molten TPE raw material, the surface parts are partially melted and welded to the foot pad body parts in the mold. After the foot pad body 1 in the mold is formed and cooled, the inserts 2 and the identification part 3 are fused with the foot pad body 1. The inserts 2 and the identification part 3 are of different colors from the foot pad body, and various patterns are formed by using a variety of contrasting colors and concave and convex patterns.

The utility model adopts a prefabricated insert of a different color from the foot pad itself to realize a multi-color pattern of the car foot pad by an in-mold insert method, and can use an ordinary injection molding machine and a mold to realize the production of multi-color pattern TPE car foot pads, which changes the difficulty of the existing multi-color TPE car foot pads requiring a special multi-color injection molding machine to produce the high cost. At the same time, there is a material flow channel inside the injection mold, the structure of the mold is simpler, the structure is reasonable and the appearance is beautiful, and the personalized needs of consumers can be met.
