[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] A metal combined seal forming mold includes an upper template 1 and a lower template 2. The bottom of the upper template 1 is fixedly installed with an upper mold 3, and the top of the lower mold 4 and at the bottom of the upper mold 3 is fixedly installed with a lower mold 4. The bottom of the upper mold 3 is provided with an upper mold core 301, and the top of the lower mold 4 is provided with a lower mold core 401 that cooperates with the upper mold core 301. The upper mold core 301 and the lower mold core 401 are used for the forming of the metal combined seal.

[0028] A cavity 5 is opened at the top of the upper mold 3. The two sides of the cavity 5 are respectively fixedly connected with a coolant input pipe 6 and a coolant output pipe 7. One ends of the coolant input pipe 6 and the coolant output pipe 7 both extend to the outside of the upper mold 3. Solenoid valves 8 are fixedly connected to the outer surfaces of the coolant input pipe 6 and the coolant output pipe 7 at the upper mold 3. A flow splitting ring 9 is fixedly connected inside the cavity 5 for splitting the coolant.

[0029] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4, the upper template 1 and the upper die 3 are fixedly installed together through a bolt structure, and the lower template 2 and the lower die 4 are also installed together through a bolt structure. The upper template 1 and the upper die 3 can be driven by an external device to move up and down, which is convenient for injection molding of metal combined seals on the upper die core 301 and the lower die core 401. When the upper die 3 and the lower die 4 are combined together, the upper die core 301 and the lower die core 401 can be closed together, and both the upper die 3 and the lower die 4 are made of heat-conducting materials.

[0030] As Figure 6 and Figure 7 , the coolant input pipe 6 and the coolant output pipe 7 connected to both sides of the cavity 5 are respectively connected to the external pipeline. When the solenoid valve is opened, the external coolant can enter the cavity 5 through the coolant input pipe 6, drive the heat inside the upper die core 301 below the upper die 3, and then be output from the cavity 5 through the coolant output pipe 7. When the coolant passes through the cavity 5, the flow dividing ring 9 has a guiding effect on the coolant, so that the coolant is divided from both sides of the flow dividing ring 9.

[0031] A closing plate 10 is arranged at the top of the cavity 5, and a plurality of fixing bolts 11 are arranged on the closing plate 10. The fixing bolts 11 are threadedly connected to the bottom of the inner wall of the cavity 5 for fixing the closing plate 10 to the top of the cavity 5.

[0032] Heat-conducting grooves 12 arranged in an annular array are opened on the inner wall of the cavity 5 and around the flow dividing ring 9, and metal heat-conducting shafts 13 are arranged in the heat-conducting grooves 12.

[0033] As Figure 3 , Figure 5 and Figure 6 , the bottom of the metal heat-conducting shaft 13 is directly connected to the metal components inside the upper die core 301, improving the heat dissipation capacity of the upper die core 301.

[0034] A heat dissipation air duct 14 is opened at the top of the upper die 3, and an L-shaped connecting air duct 15 is opened at the top of the closing plate 10. The L-shaped connecting air duct 15 is communicated with the heat dissipation air duct 14.

[0035] As Figure 1 and Figure 5 , by using the communication between the L-shaped connecting air duct 15 and the heat dissipation air duct 14, the external air flow can pass above the upper die 3 to form heat dissipation above the closing plate 10.

[0036] Rectangular plates 16 are fixedly installed on the same side of the upper template 1, the upper die 3 and the lower die 4 through bolts, and a control handle 17 is fixedly connected to one side of the rectangular plate 16.

[0037] As Figure 1, by fixing the control handle 17 on one side of the upper template 1, the upper mold 3 and the lower mold 4, it is convenient to carry them when the upper template 1, the upper mold 3 and the lower mold 4 are not installed.

[0038] A semiconductor refrigeration plate 18 is fixedly connected to the bottom of the lower template 2. The semiconductor refrigeration plate 18 adopts an annular design. A guide shaft 19 is fixedly installed on the lower template 2. The top of the guide shaft 19 sequentially penetrates through the lower mold 4, the upper mold 3 and extends into the interior of the upper template 1.

[0039] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4 , the top of the guide shaft 19 sequentially penetrates through the lower mold 4, the upper mold 3 and extends into the interior of the upper template 1, playing a role in guiding and positioning between the lower template 2, the lower mold 4, the upper mold 3 and the upper template 1, facilitating the quick alignment between the lower template 2, the lower mold 4, the upper mold 3 and the upper template 1. The semiconductor refrigeration plate 18 is closely attached to the lower mold 4, which can assist in dissipating heat from the metal combined seal in the upper and lower die cores 401 of the lower mold 4.

[0040] Compared with the related technology, a metal combined seal forming mold provided by the present utility model has the following beneficial effects:

[0041] The mold proposed by the present utility model can perform injection molding of metal combined seals between the upper die core 301 and the lower die core 401. After the injection molding is completed, the coolant enters the cavity 5 to cool the upper die core 301, and the semiconductor refrigeration plate 18 cools the lower die core 401 from below, so that the metal combined seal formed between the upper die core 301 and the lower die core 401 can be quickly cooled and demolded, improving the forming speed of the mold for the metal combined seal.

[0042] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
