In order to reduce the problem of different colors of TPU affecting each other and causing product defects, this case was proposed. Summary of the invention

[0030] Example 2
[0031] Reference Figure 1-Figure 4 This embodiment provides a fully automatic TPU two-color injection foaming molding machine. In order to further ensure the melting effect of the TPU material, this embodiment facilitates the reasonable setting of the interval heating temperature value, so that the TPU material gradually melts, avoiding the adverse effects caused by the large temperature value change span (such as the temperature is too high when the TPU is solid, which easily leads to paste); this embodiment also plays a connecting role, so that the semi-solid TPU material can enhance the thermal conductivity in a gradually shrinking space, so that the TPU material can be fully melted. In terms of structure, a simple structure is used to solve the corresponding technical problems, effectively controlling the cost on the basis of the traditional fully automatic TPU two-color injection foaming molding machine, and also improving the use effect of the equipment.
[0032] This embodiment further provides the following technical features on the basis of Embodiment 1: a transition component is provided between the first extrusion port 111, the second extrusion port 120 and the merging head 112, a preheating space 106 is provided in the transition component, one end of the transition component is connected to the corresponding extrusion cavity 102, and the other end is connected to the merging head 112.
