In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the following embodiments.
First, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with at least one implementation of the invention is included. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Secondly, the utility model discloses utilize structural schematic diagram etc. to carry out the detailed description, when detailing the embodiment of the utility model, for the convenience of explanation, the schematic diagram that shows second grade material returned structural configuration can not do local enlargement according to general proportion, moreover the schematic diagram is the example only, and it should not limit here the scope of the protection of the utility model. In addition, the actual fabrication process should include three-dimensional space of length, width and depth. Example one
Referring to fig. 1, fig. 1 is a schematic structural diagram of a secondary material returning structure according to the present invention. As shown in fig. 1, the material returning device comprises a material returning ring 1, a material returning device 2 and a mold spring 3, wherein the material returning device 2 is sequentially divided into a material returning head (not shown), a material returning column (not shown) and a material returning chassis (not shown) from top to bottom, the material returning head, the material returning column and the material returning chassis are of an integral structure, the diameter of the material returning head gradually increases from top to bottom, the material returning column is cylindrical, the upper end of the material returning column is connected with the material returning head, the lower end of the material returning column is connected with the material returning chassis, the diameter of the material returning chassis is larger than that of the material returning column, the material returning ring 1 is of a hollow structure, the material returning ring 1 is sleeved on the material returning column, the material returning ring 1 comprises a material returning ring column (not shown) and a material returning ring base (not shown), the material returning ring column and the material returning ring base are of an integral structure, and the outer diameter of the material returning ring column is smaller than that of the material returning ring base, the inner diameter of the material returning ring column is equal to that of the material returning ring base, the die spring 3 is sleeved on the material returning column, the upper end of the die spring 3 is in contact with the material returning ring base, and the lower end of the die spring 3 is in contact with the material returning chassis.
