Chamber one side therein, the conical lower portion of approach cooling chamber, enter the another side of cooling chamber, return again to cooling water channel, enhance cold
But the water circulation ability of intracavity, thus improve cooling effect.
Preferably, the inwall of the inwall of described cooling water channel and described cooling chamber is equipped with waterproof coating layer.
By adopting technique scheme, in the inwall of cooling water channel and the inwall brushing waterproof coating layer of cooling chamber, can
To prevent cooling water from penetrating in core, lead to core dilatancy, the quality of impact product, meanwhile, penetrate into cold in core
But water, is easily damaged core.
Preferably, described waterproof coating layer is aerosil modification acrylate waterproof coating layer.
By adopting technique scheme, aerosil modification acrylate water-repellent paint has high fillibility, fills out
Fill up speed fast, cooling water channel and the production cycle of cooling chamber application can be greatly shortened, tough and tensile, cohesive force after coating, can be formed
Very strong elastic water-proof film, this waterproof membrane elongation at break is high, and resistance capacity to deformation is strong, reaches and prevents from for a long time cooling down water penetration
Effect, and aerosil modification acrylate water-repellent paint safety and environmental protection, without harmful chemical substance.
Secondary objective of the present utility model is to provide a kind of injection mold of good cooling results.
A kind of injection mold, including core as above.
By adopting technique scheme, using the injection mold of above-mentioned core, product cooling can be made uniformly, in mould
The stability in portion improves, and effectively raises the mold use life-span, increased the quality of injecting products.
In sum, this utility model has the advantages that：
1st, the setting of cooling chamber, can accelerate rate of cooling, makes the cooling of whole product equal to the bossing in product
Even, reach the purpose strengthening product quality；
