With the above modification, it is convenient to inject the heating medium into the heating passage 31. In this embodiment, one end of each of the two heating channels 31 is communicated with each other through a second connecting channel, the other end of one of the heating channels 31 is sealed by a sealing gasket, and the other end of the other heating channel 31 is in an open state, so that only by injecting a heating medium into the open end of the heating channel 31, the two heating channels 31 can both have the heating medium through the second connecting channels, and the heating medium is convenient to add.

As an improvement of the present invention, a cooling block is disposed in the forming mold at the main pipe cavity 28, the main pipe cavity 28 is formed on the cooling block, the plurality of cooling channels 29 are disposed on the cooling block, the plurality of cooling channels 29 are communicated with the cooling block, so that the processing is convenient, and the heat transfer efficiency is high, a heating block is disposed in the forming mold at the branch pipe cavity 30, the branch pipe cavity 30 is formed on the heating block, the plurality of heating channels 31 are disposed on the heating block, and the plurality of heating channels 31 are communicated with the heating block, so that the processing is convenient, and the heat transfer efficiency is high.

In this embodiment, the number of the cooling blocks is two, the two cooling blocks are arranged on two sides of the heating block, the two cooling blocks are respectively provided with a main pipe cavity 28, the heating block is provided with a main pipe connecting cavity for communicating the main pipe cavities 28 on the two cooling blocks, and the plurality of heating channels 31 are arranged on the heating block, namely, the main pipe cavities 28 and the cooling channels 29 are firstly processed on the cooling blocks, then the branch pipe cavities 30 and the heating channels 31 are processed on the heating block, and then the cooling blocks and the heating block are arranged in the forming mold, so that the branch pipe cavities 30, the main pipe cavities 28, the heating channels 31 and the cooling channels 29 can be conveniently processed.

The forming die comprises an upper die holder 21 and a lower die holder 22, each cooling block comprises an upper cooling block 24 arranged in the upper die holder 21 and a lower cooling block 25 arranged in the lower die holder 22, and the heating block comprises an upper heating block 26 arranged in the upper die holder 21 and a lower heating block 27 arranged in the lower die holder 22. When the upper die holder 21 is arranged on the lower die holder 22, the upper cooling block 24 and the lower cooling block 25 cooperate to form a complete cooling block to form a main pipe cavity 28, and the upper heating block 26 and the lower heating block 27 cooperate to form a complete heating block to form a branch pipe cavity 30, so that the cooling block and the heating block are installed in the die through the improvement.

Go up and be equipped with locating piece 32 between cooling block 24 and the upper die base 21, it inlays to locate to go up locating piece 32 one end go up in the cooling block 24, the other end of going up locating piece 32 inlays and locates in the upper die base 21 to in with last cooling block 24 fix a position, guaranteed the installation accuracy, but also can be spacing with last locating piece 32, be equipped with down the locating piece down between cooling block 25 and the die holder 22, locating piece one end inlays to be located down in the cooling block 25, the other end of locating piece inlays to be located down in the die holder 22 to in with cooling block 25 fixes a position down, guaranteed the installation accuracy, but also can be spacing with locating piece down.

The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present invention are included in the scope of the present invention.
