[0026] Insert and fixedly connect the injection port assembly 8 through the middle of the upper template 1. A heat preservation plate 2 is fixedly connected below the upper template 1. A clamping part groove 201 is formed inside the upper part of the heat preservation plate 2. The upper part of the runner assembly 13 is fixedly connected inside the clamping part groove 201. At the same time, the lower part of the runner assembly 13 passes through the lower part of the heat preservation plate 2, and the middle part of the upper part of the runner assembly 13 is inserted and fixedly connected to the bottom of the injection port assembly 8.

[0027] After inserting the injection port assembly 8 into the upper template 1, a runner assembly 13 is arranged inside the heat preservation plate 2 provided below the upper template 1. The lower part of the injection port assembly 8 is inserted into the runner assembly 13 to inject plastic into its interior, and the injection liquid is conveyed to the entire mold interior through the runner assembly 13.

[0028] Furthermore, the upper die base 3 is fixedly connected below the heat preservation plate 2. The middle part of the runner assembly 13 is inserted and slidably connected inside the upper die base 3. An upper die core groove 301 is formed inside the bottom of the upper die base 3. The upper die core plate 9 is clamped and fixedly connected inside the upper die core groove 301, and the lower part of the runner assembly 13 is inserted into the upper die core plate 9.

[0029] There is an upper die core plate 9 inside the bottom of the upper die base 3 provided below the heat preservation plate 2. After the lower part of the runner assembly 13 is inserted into the upper die core plate 9, since an upper part of the cavity is provided at the bottom of the upper die core plate 9, the injection liquid is injected into the upper part of the cavity below the upper die core plate 9 through the runner assembly 13.

[0030] Furthermore, a lower die core groove 401 is formed inside the upper part of the lower die base 4. The lower die core plate 10 is clamped and fixedly connected inside the lower die core groove 401. The bottom of the upper die core plate 9 is pressed against the top of the lower die core plate 10, and a cavity is formed between the upper die core plate 9 and the lower die core plate 10.

[0031] After the lower die base 4 and the upper die base 3 are combined, the lower die core plate 10 above the lower die base 4 and the upper die core plate 9 are also combined. In this way, the injection liquid inside the runner assembly 13 will be injected into the complete cavity at the combined part of the two.

[0034] The tops of support blocks 5 are fixedly connected to both sides below the lower die base 4. The tops of both sides of the lower template 6 are fixedly connected to the bottoms of the support blocks 5, and a plurality of support columns 16 are fixedly connected to the middle part above the lower template 6.

[0035] Furthermore, a sliding connection top plate assembly 7 is sleeved outside the support column 16, and there are gaps between both sides of the top plate assembly 7 and the inner sides of the support blocks 5. The top column assemblies 11 are fixedly connected to the four corners of the top plate assembly 7.

[0036] After the lower die base 4 is integrally connected to the lower template 6 through the support blocks 5, since the support column 16 is provided above the lower template 6, the top plate assembly 7 can move up and down between the lower die base 4 and the lower template 6 while relying on the support column 16.

[0037] Furthermore, the upper parts of the top column assemblies 11 are inserted into and slidably connected to the inside of the lower die base 4, and the tops of the top column assemblies 11 are in close contact with the bottom of the upper die base 3.

[0038] When the top column assemblies 11 provided above the top plate assembly 7 move up and down following the top plate assembly 7, the top column assemblies 11 will push open the upper die base 3 above and its upper structure, forming an upper mold opening.

[0039] Furthermore, a plurality of ejector rods 12 are fixedly connected to the middle of the top plate assembly 7, and the plurality of ejector rods 12 are arranged in an orderly manner corresponding to the cavities.

[0041] Since the ejector rods 12 above the top plate assembly 7 are inserted into the lower die core plate 10, the tops of the ejector rods 12 are placed below the product part inside the mold. When the top plate assembly 7 rises, it will drive the ejector rods 12 to eject the product part from inside the mold.

[0042] Working principle:

[0043] A heat preservation plate 2 is provided below the upper template 1, and an injection port assembly 8 is inserted into the middle of the upper template 1. At the same time, a runner assembly 13 is provided inside the heat preservation plate 2. After the injection port assembly 8 is inserted into the runner assembly 13 below, the injection liquid in the injection port assembly 8 will be injected into the runner assembly 13, and then injected into the mold interior by the runner assembly 13. A upper die base 3 is provided below the heat preservation plate 2, and the lower die base 4 is pressed below the upper die base 3. An upper die core plate 9 and a lower die core plate 10 are respectively provided inside them and pressed against each other, and a complete cavity is formed between the upper die core plate 9 and the lower die core plate 10. The runner assembly 13 is inserted below into the cavity to form a product part. A support block 5 and a lower template 6 are provided below the lower die base 4, and a support column 16 provided above the lower template 6 supports the top plate assembly 7, so that the top plate assembly 7 can move up and down between the lower die base 4 and the lower template 6. At the same time, a ejector pin assembly 11 and a ejector rod 12 are respectively provided above the top plate assembly 7. When the mold is opened, an external force is applied to the top plate assembly 7, so that the top plate assembly 7 rises, and both the ejector pin assembly 11 and the ejector rod 12 rise. The ejector pin assembly 11 will push against the upper die base 3 and the structures above it to disengage from the lower die base 4, so that the upper die core plate 9 and the lower die core plate 10 are disengaged. At the same time, the ejector rod 12 is also rising. Since the top of the ejector rod 12 is placed below the product part, then the ejector rod 12 will eject the product part out of the die core groove above the lower die core plate 10 at this time, so that the complete demolding inside the mold is achieved.
