Step B, mold prepares：Prepare two molds, respectively the first mold and the second mold, first mould therein
It is provided with pattern in the die cavity of tool；
Step C, primary injection molding：The material A is molded to first mold, the injection molding expects pipe of the first mold is controlled
Temperature be T1, be molded 1 postcooling preset time t 2 of preset time t, open the first mold, take out intermediate products；
Step D, quadric injection mould：The intermediate products are positioned in second mold, the injection molding of the second mold is controlled
The temperature of expects pipe is T2, T2<The material B is molded to second mold by T1, acquires the injection molding material of second mold
Temperature T in pipe is surveyed, when T is surveyed>When T2, the temperature of the injection molding expects pipe of second mold is reduced, it is cold after injection molding preset time t 3
But preset time t 4；
Step E, the second mold molds, and obtains product.
Further, the material B includes at least one of ABS, PC, ABS and PMMA.
Further, the material A includes at least one of PBT and PET.
Further, 280<T1<320℃.
Further, 240<T2<280℃.
Further, t1 20-30s.
Further, t2 2-15s.
Further, t3 20-30s.
Further, t4 2-15s.
Beneficial effects of the present invention are as follows：
Double-colored product injection molding forming method provided by the invention, by acquiring and controlling the temperature in the second mold, and makes
The melting temperature for obtaining material B is less than the melting temperature of material A, ensure that temperature of temperature when quadric injection mould less than primary be molded when
Degree, ensure that the pattern on intermediate products is unaffected in quadric injection mould, improves the quality of product.
