A molding device of a synthetic resin product having multi-color free patterns is provided to prevent color and pattern from being removed even in case abrasion is generated in a product by forming the same colors and free patterns at the inside and outside of synthetic resin products through fusing synthetic resin chips having various colors. Two or more hoppers(5) are prepared to supply synthetic resin chips respectively. Two or more cylinders(1) are installed with a piston(3). The cylinder comprises a heater(6) to fuse the synthetic resin chip supplied from the hopper. In the front end of the cylinder, a main pipe(8) is set up. The main pipe collects synthetic resin solution fused inside the cylinder and extrudes the synthetic resin solution through an injection mold(30).
