the heat dissipation assembly comprises a water retaining frame fixedly arranged at the top end of an upper forming die, wherein multiple flow plates are uniformly distributed in the water retaining frame, one side of the upper forming die is connected with a water inlet pipe, one end of the side wall of the upper forming die, which is opposite to the water inlet pipe, is connected with a water outlet pipe, a plurality of water passing grooves are formed in the water retaining frame, and the flow plates are distributed in a staggered manner;
the bottom end of the upper forming die is fixedly provided with an upper hot-pressing die, and the upper end of the lower forming die is provided with a lower hot-pressing die; the hot-pressing upper die is a male die, and the hot-pressing lower die is a female die.
As a further description of the above technical solution:
and the side wall of the lower forming die is provided with a feeding port.
As a further description of the above technical solution:
one end of the water inlet pipe, which is far away from the upper die of the forming die, is connected with an external cooling water tank.
In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:
according to the utility model, by the arranged heat dissipation assembly, after a product is molded, the interior of the mold can be rapidly cooled by using cooling water and the flow distribution plate, so that the production efficiency is improved; through dividing the mould into type mould, shaping lower mould, hot pressing mould and hot pressing lower mould, and all mould drawing of patterns angles are 0, avoided the product to appear the unsaturated fold scheduling problem that appears in R angle when the shaping.
