Description

Sole mold with conformal cooling ducts

technical field

The utility model relates to a mold structure, in particular to a shoe sole mold with a conformal cooling pipeline.

Background technique

The cooling system of the injection mold occupies a very important position in the structure of the injection mold, and is the key to improving the quality of injection molding products and improving the efficiency of injection molding. The traditional cooling water channel is generally composed of a group of straight opening passages. In order to form a closed flow channel, except for the inlet and outlet, other openings need to be sealed with plugs. This cooling technology has the following problems: due to the limitation of the processing technology, the cooling water channel cannot be set according to the demand, resulting in low cooling efficiency and poor cooling effect.

Generally, the cooling circuit inside the injection mold is usually processed by drilling. Restricted by the drilling process, only straight holes can be processed. When the cooling circuit is more complicated, the mold needs to be divided into pieces first, and then drill holes from both sides. For molds with arc-shaped curved surfaces or stepped molds, linear segment approximation is required, which reduces cooling efficiency.
