An object of the utility model is to provide an injection mold cooling water course structure optimizes the cooling water course design, promotes the anterior cooling rate of mold core.
To achieve the purpose, the utility model adopts the following technical proposal:
an injection mold cooling water channel structure comprising: the die comprises a die plate and a die core, wherein the die core is arranged in the die plate and protrudes outwards, an embedded groove corresponding to the die core is arranged on the front surface of the die plate, a plurality of blind holes are arranged in the back surface of the die core in an inwards concave manner, a water inlet hole and a water drain hole which are communicated with the embedded groove are oppositely arranged on two sides of the die plate, a water inlet groove corresponding to the water inlet hole and a water drain groove corresponding to the water drain hole are arranged on the edge of the back surface of the die core, a first inclined hole communicated with the tail end of the blind hole is arranged in the water inlet groove, and a second inclined.
And the back of the template is provided with a bolt connected with the mold core.
Wherein, be provided with the shutoff piece in the blind hole.
The plugging piece is a threaded column, and an internal thread corresponding to the threaded column is arranged in the blind hole.
The diameters of the first inclined hole and the second inclined hole are the same and smaller than the diameter of the blind hole.
Wherein, be provided with the sealing washer that is located mold core all around and the back in the embedded groove.
And pipe joints are respectively arranged at the outer ends of the water inlet hole and the water discharge hole.
The utility model has the advantages that: the utility model provides an injection mold cooling water course structure makes the water course extend to the mold core front portion through the blind hole, utilizes first inclined hole to deliver to the blind hole end to the cooling water, carries out the anterior direct cooling of mold core, has promoted cooling rate greatly, is favorable to shortening the cooling time long, promotes production efficiency, and the position of blind hole is nimble, can carry out the design of one or more blind holes according to mold core structure, satisfies the needs of production.
