Abstract

The invention relates to a mold heating and cooling rod which comprises a heating and cooling rod body and a heating element, a cooling thermal insulation hole for introducing a cooling medium when a mold needs to be cooled and discharging the cooling medium when the mold needs to be heated and a heating element accommodating hole are arranged in the heating and cooling rod body along the axial direction, and the heating element is mounted in the heating element accommodating hole; the mold capable of realizing rapid cooling and rapid heating comprises a mold core and the heating and cooling rod, and the heating and cooling rod is in contact with the mold core; and one side of the heating and cooling rod which is provided with the heating element is near to a molding surface of the mold core. The advantages are that, as the molding surface can be rapidly and evenly heated and cooled and rapidly heated to the temperature which is near to or equal to that of melting materials, a molded product has the advantages of good quality, difficult production of weld marks, flow marks, surface bubbles and the like, even color and luster, even density of the product, small shrinkage and ability of reducing the injection pressure and the product deformation caused by residual stress after consolidating and molding the molten materials.

Description

technical field

[0001] The invention relates to a mold heating and cooling rod for heating and cooling a mold and a mold capable of realizing rapid cooling and rapid heating, in particular to a mold heating and cooling rod on a molding machine such as injection or die-casting and a mold capable of rapid cooling and rapid heating mold. Background technique

[0002] The injection molding method of plastic or metal refers to injecting molten plastic or metal into the molding cavity of the mold, and obtaining a product consistent with the cavity after cooling and molding. In the injection molding process, a heating and cooling device that can realize rapid cooling and heating of the mold is required to control the temperature of the mold.

[0003] The existing heating rod can only provide heating function, such as electric heating rod, when the mold needs to be heated, the electric heating rod does not have the function of heat insulation. Rapid and uniform heating; when cooli...
