Be further used as the improvement of technical solutions of the utility model, in described cold water jacket, be provided with and be funnelform cup chamber, described die cavity is accessed in the bottom in cup chamber, described attached water road is the annular of walking around whole cup chamber, attached water road forms the water inlet docking with water inlet interface in a side of cold water jacket, attached water road forms at the opposite side of cold water jacket the delivery port docking with water outlet mouthpiece.

Be further used as the improvement of technical solutions of the utility model, between the inwall of described cold water jacket and cast gate, be provided with sealing ring in the above and below of water inlet, delivery port respectively.

Be further used as the improvement of technical solutions of the utility model, described cold water jacket is that 3D prints product.

Be further used as the improvement of technical solutions of the utility model, described main water route is the rounded boring in cross section, and the diameter of section in main water route is D, 12mm≤D≤14mm.

Be further used as the improvement of technical solutions of the utility model, the diameter of section on described attached water road is d, 8mm≤d≤10mm, and attached water road is h apart from the minimum range of cold water a set of cups cavity wall, 10mm≤h≤12mm.

The beneficial effects of the utility model: the utility model arranges cold water jacket in cast gate, the attached water road in the main water route of access is set simultaneously in cold water jacket, attached water line structure form is substantially equal to the structural form of cold water jacket, in the production process of product, ensure that product gate portions exchange heat in the cooling process with heating is consistent, effectively reduce the production cycle of mould, improved mold heated cooling effectiveness, ensured mould production stability.
