[0042] Fourth positioning column 15, fourth positioning column 15 is vertically fixedly connected on lower die holder 2, and second insert 16 is sleeved on the top end of fourth positioning column 15.
[0043] For some product structures requiring multiple groups of inserts, the shape of the insert has a reverse structure in the injection mold due to the coupling requirement, and the position requirement is relatively strict when the insert is placed in the cavity, and it is easy to deviate, which leads to extrusion of the insert when clamping, and finally affects the product quality. In the application, first, two groups of first inserts 14 are stacked on lower die holder 2, wherein the middle ends of two groups of first inserts 14 correspond up and down, and the second ends of two groups of first inserts 14 are inserted into lower die holder 2 vertically;Then, the horizontal displacement of the first end of two groups of first inserts 14 is limited by first positioning assembly, and the second end of two groups of first inserts 14 is further limited vertically by second positioning assembly;Second insert 16 is limited by the top end of fourth positioning column 15, so that all inserts are positioned on lower die holder 2. The application can accurately position multiple groups of inserts, effectively improve the injection quality of products.
[0044] The structure of two groups of first inserts 14 in the application is not completely the same, which is used for the product structure of multiple inserts.
[0045] Further optimization scheme, first positioning assembly includes:
[0046] The first positioning column 10 is vertically fixed and connected to the lower mold base 2, and the first end of the first insert 14 is horizontally limited to the top end of the first positioning column 10.
[0047] The second positioning column 11 is vertically fixed and connected to the lower mold base 2, and the second end of the first insert 14 is placed on the second positioning column 11.
[0048] The boss (not marked in the figure) is arranged at the top of the first positioning column 10, and the first end of the first insert 14 is sleeved on the boss.
[0049] Before clamping, the second end of the two groups of first inserts 14 is vertically inserted and fitted into the gap (not shown in the figure) on the lower mold base 2 and placed on the top of the two groups of second positioning columns 11, and then the first end of the two groups of first inserts 14 is sleeved on the boss at the top end of the two groups of first positioning columns 10, and the top end of the first positioning column 10 is kept, so that the first end of the two groups of first inserts 14 cannot rotate around the first positioning column 10; After ejection, the second end of the two groups of first inserts 14 is outside the product 8 and is not wrapped by injection molding.
[0050] Further optimization scheme, the second positioning assembly comprises:
[0051] The first slider 4 is horizontally slidably connected to the lower mold base 2, and the first slider 4 is lifted by the upper mold base 1 to approach or move away from the second end of the two groups of first inserts 14.
[0052] The second slider 13 is fixedly connected to the first slider 4 at the first end, and the second end of the two groups of first inserts 14 is vertically limited by the second end of the second slider 13.
[0053] The third positioning column 12 is fixedly connected to the second end of the second slider 13, and when the mold is clamped, the two groups of third positioning columns 12 respectively pass through the second end of the two groups of first inserts 14, wherein the third positioning column 12 is a tapered column, the large-diameter end of the third positioning column 12 is fixedly connected to the second slider 13, and the small-diameter end first passes through the second end of the first insert 14.
[0054] When the second end of the two groups of first inserts 14 is placed on the top of the two groups of second positioning columns 11 and the first end of the first insert 14 is limited, at this time, the second end of the two groups of first inserts 14 is arranged in parallel, and then the lower mold base 2 is lowered (clamped), the first slider 4, the second slider 13 and the third positioning column 12 are gradually approached to the second end of the first insert 14, the second slider 13 slides into the lower mold base 2, and the large-diameter end of the third positioning column 12 is fitted into the positioning hole (not marked in the figure) of the second end of the first insert 14; Complete the positioning of the two groups of first inserts 14.
[0055] The second end of the second slider 13 is further provided with an adapter block 3, which is located between the two groups of third positioning columns 12. When the large-diameter end of the third positioning column 12 is adapted in the positioning hole at the second end of the first insert 14, the adapter block 3 is slid into the second end between the two groups of first inserts 14 and is in contact with the opposite surface between the second end of the first insert 14. During the process of mold injection, it prevents glue overflow, so as to achieve the purpose that the second end of the two groups of first inserts 14 is exposed outside the product 8 and is not wrapped by injection molding.

The two groups of first inserts 14 and the second insert 16 are respectively located in the mold cavity, and the product 8 is formed after glue is injected into the mold cavity. The bottom end of the second insert 7 and the upper mold base 1 separate the pin feet of the first end of the two groups of first inserts 14 and separate the pin feet from the mold cavity, so as to facilitate the exposure of the pin feet outside the product 8.
[0059] Further optimization scheme, further comprising:
[0060] The inclined hole 9 is arranged on the first slider 4.

[0062] When the mold is closed, the upper mold base 1 moves downward, the low end of the inclined guide column 5 extends into the inclined hole 9, and as the upper mold base 1 continuously moves downward, the inclined guide column 5 pushes the first slider 4 to slide towards the first insert 14, until the large-diameter end of the third positioning column 12 is adapted in the positioning hole at the second end of the first insert 14. A plurality of springs are arranged between the first slider 4 and the lower mold base 2. After the mold is closed, the plurality of springs are in a compressed state. When the mold is opened, the first slider 4, the second slider 13 and the third positioning column 12 are driven away from the product 8 by the spring rebound force and the thrust of the inclined guide column 5.
[0063] Further optimization scheme, further comprising:
[0064] The ejector pin is vertically slidably connected in the lower mold base 2 and is driven to rise and fall by the air cylinder. The plurality of ejector pins are located below the product 8.
[0065] After the product 8 is shaped and the mold is opened, the product 8 is ejected from the cavity by starting and extending the cylinder.
