Embodiment Construction
[0020] see Figure 1-4 , the present invention includes a cooling plate 1, a die plate 2, a manifold 3, a core support plate I4, a core support plate II5, and a mold body 6 are sequentially stacked into a die head, and a cavity 11 is provided in the die head, located at The cavity 11 of the mouth template 2 is a stable section, the cavity 11 located in the manifold 3 is a compression section, and the cavity 11 located in the support plate I, II 4, 5 and the mold body 6 is a feed splitting section. The feature is that there are upper, middle and lower rows of mandrels 8, 9 and 10 distributed in the cavity 11, forming a four-layer flow, in which two rows of mandrels 8 and 9 (see Figure 8 , 9 , 10. The structure of the upper row of mandrels or the lower row of mandrels is basically the same as the existing mandrel structure, except that it is bent outwards and deformed) in the compression section, it is bent and deformed outwards, and in the feed diversion section, it is folded...
