Detailed Description

The following will explain the technical solution of the fourth-time injection molding product and the mold thereof according to the present invention in detail with reference to the embodiments.

As shown in fig. 1-2. A four-time injection molding product comprises an upper shell 1 and a lower shell 2; a square through hole 3 is formed in one side of the lower shell 2, and an electroplating part 4 is injected into the square through hole 3; two circular through holes 5 are formed in one side of the upper shell 1, and a conductive particle 6 and TPU soft rubber 7 wrapping the lower portion of the conductive particle 6 are injected at the position of the circular through hole 5 of the upper shell 1.

3-8, the mold for manufacturing a four-time injection molding product comprises a turntable 8 and an injection mold 9, wherein the injection mold 9 comprises 4 upper molds 10 and at least 6 identical lower molds 11, and the lower molds 11 are detachably connected to the turntable 8; the 4 upper dies 10 are respectively a first upper die 12, a second upper die 13, a third upper die 14 and a fourth upper die 15 which are connected in an injection molding manner in sequence; after the first upper die 12 and the lower die 11 are assembled, a first cavity for molding the upper shell 1 and the lower shell 2 is formed; after the second upper die 13 and the lower die 11 are closed, a second cavity for molding the electroplating component 4 is formed; after the third upper die 14 and the lower die 11 are closed, a third cavity for molding the conductive particles 6 is formed; and after the fourth upper die 15 and the lower die 11 are matched, a fourth cavity for forming the TPU soft rubber 7 is formed.

The at least 6 identical lower dies 11 are respectively composed of a left male die and a right male die, and two circular grooves 16 are formed in the upper portion of the left male die; the 4 upper dies 10 of the injection mold 9 are respectively composed of a left female die and a right female die, the left female die of the first upper die is provided with a round convex block 17, and the right groove of the first upper die 12 is provided with a square convex block 18; the right grooves of the second upper die 13, the third upper die 14 and the fourth upper die 15 are all convex-block-free concave dies; the left concave die of the second upper die 13 is the same as the left concave die of the first upper die 12; the left concave die of the third upper die 14 is provided with two first concave blocks 19 for molding the conductive particles 6; and the left groove of the fourth upper die 15 is provided with two second concave blocks 16 for forming the TPU soft rubber 7.

The working process is as follows: when the turntable 8 rotates one die, the upper die 10 and the lower die 11 are closed, and the first cavity, the second cavity, the third cavity and the fourth cavity are subjected to injection molding; because the lower dies 11 are completely the same and only 4 upper dies 10 are different, the 4 injection molds 9 can simultaneously perform injection molding, the working efficiency is higher, the labor cost is saved due to the pure mechanical production, and the complex process becomes simple.
