[ detailed description ] embodiments

In order to make the technical problems, technical solutions and advantageous effects solved by the present application more clear and obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 1 to 4, this application embodiment provides a lid mould behind formula cell-phone is advanced to position, including cover half subassembly 1 and movable mould subassembly 2, cover half subassembly 1 includes fixed die plate 11 and locates the fixed die benevolence 12 on the fixed die plate 11, movable mould subassembly 2 includes movable mould board 21 and locates the movable mould benevolence 22 on the movable mould board 21, fixed die benevolence 12 with the movable mould benevolence 22 forms the die cavity 3 of lid behind the cell-phone of moulding plastics during the compound die, be equipped with on the fixed die plate 11 position 13, run through the sprue 14 of position 13 and slide a plurality of fore-set 15 of setting on fixed die core 12, be equipped with on the fore-set 15 with the subchannel 16 of sprue 14 intercommunication, the subchannel 16 through runner 17 with the die cavity 3 is linked together.

When the mold is closed, molten plastic is filled into the cavity through the main runner, the sub-runner and the pouring gate and then cooled to produce a product, and the ejection column ejects the product during product demolding, wherein the main runner 14 and the sub-runner are respectively positioned on the movable action and the ejection column, so that an additional fixed glue feeding structure is not required to be arranged, the material is saved, and the pouring gate is not easy to mold due to the movement of the pouring gate along with the ejection column during product demolding.

Accordingly, the top pillars 15 are distributed on both opposite sides of the core insert 12.

In order to reduce the processing difficulty, the top pillar 15 is arranged with the fixed mold core 12 in a sliding mode through a sliding hole, a shunting groove is formed in the top pillar 15, and the shunting channel 16 is formed between the shunting groove and the wall of the sliding hole.

In this embodiment, the main flow channel 14 includes a horizontal flow section 141 and an oblique flow section 142, which are arranged in a downward inclined manner, and an end of the oblique flow section 142 is communicated with the branch flow channel 16. Molten plastic enters from bottom to top, the cavity is filled more fully, and bubbles are avoided.

Preferably, the end of the oblique flow section 142 is flared with a gradually decreasing radial dimension.
