in a preferred embodiment, because the number of the radiating fins of the product is large and the radiating fins of the product are deep, the wrapping force reaches 15-25T according to theoretical calculation, the product is locally deformed and the wrapping force is larger in actual production, so that the product is ejected by using a spring, the ejection force is not enough, the radiating fins of the product pushed by the auxiliary ejection assembly 13 need to be added in the fixed die, the auxiliary ejection assembly 13 needs to be ejected timely, if the ejection speed of the fixed die cannot follow up the die opening, the product is pulled and deformed by the fixed die or even pulled and cracked, and therefore before the die opening, the auxiliary ejection assembly 13 needs to be in a working state to ensure that the auxiliary ejection assembly 13 timely ejects the radiating fins of the product away from the fixed die, so that the product is far away from the fixed die along with the movable die.

The forming portion 112 includes a plurality of segments 1121, and the segments 1121 are stacked so that a cavity for forming a heat sink is formed between two adjacent segments 1121;

the auxiliary pushing assembly 13 includes a pushing rod 135 and a pushing module 132 for driving the pushing rod 135, and under the driving of the pushing module 132, the pushing rod 135 penetrates through the segments 1121 to extend into the cavity between the segments 1121, so as to push the heat sink formed in the cavity away from the forming portion 112.

In current former, because product fin thickness is thinner, correspond the mould characteristic and be the deep trouth, the mould processing difficulty is difficult to polish to the mould surface, consequently blocks the risk of product extremely high, and in case the mould blocks the product, remains and is difficult to the clearance at the inside solidification metal of mould, maintains for the mould and causes very big influence. And this forming mechanism through splitting all fin into piecings 1121 for individual piecings 1121 is conveniently processed, reduces the processing cost, simultaneously, even the product is blocked in the mould the inside, also can clear up the solidification metal through dismantling the piece 1121 fast.
