Drawings
Fig. 1 is a schematic view of a fixed mold part structure of a plastic mold with an optimized runner structure and a nozzle structure of the mold according to the present invention;
fig. 2 is a schematic diagram of a multi-channel structure of the conventional apparatus.
The specific implementation mode is as follows:
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
As shown in fig. 2, the flow channel structure is a conventional flow channel structure, and the flow channel structure includes a glue inlet flow channel 10a, a main flow channel 22a and a plurality of flow channel groups 21a, wherein the main flow channel 22a is connected to the glue inlet flow channel 10a and the plurality of flow channel groups 21 a; and the plurality of flow channel groups 21a are arranged at intervals.
As shown in fig. 1, it is the utility model provides a pair of plastic mold with optimize runner structure, plastic mold with runner optimal design includes movable mould (not shown) and cover half 10, be provided with a plurality of die cavities 11 on the cover half 10 and optimize runner 20. The optimized runner 20 includes a glue inlet runner (not shown) at a central position and a plurality of runner groups 21 perpendicular to and connected to the glue inlet runner, wherein the glue inlet runner is disposed on the movable mold, and in this embodiment, an end of the glue inlet runner is disposed at a central position of the plurality of runner groups 21. Further, a plurality of runner groups 21 are provided around the corresponding mold cavity 11.
The runner group 21 comprises two main runners which are connected with the glue inlet runner and are arranged vertically, a middle runner 23 connected with the two main runners and a plurality of sub runners 24; the two main runners and the middle runner 23 enclose a quadrilateral structure and are arranged around the die cavity 11.
