[0002] In die-casting molds, various core inserts are often used. Using core inserts can improve the processing accuracy of products, significantly extend the service life of the molds, and reduce the processing and manufacturing costs of the molds.

[0003] However, for some slender core inserts, due to the small bottom position, only one water tank can be set instead of multiple water tanks, and the coolant cannot circulate and dissipate heat well in the core insert, thus significantly weakening the cooling effect of the core insert. In view of the above problems, a core insert cooling device is proposed. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a core insert cooling device, which can effectively solve the problems in the background art.

An inlet liquid groove and an outlet liquid groove are opened in the connecting column. The inlet liquid groove is threadedly connected with an inlet liquid joint, and the outlet liquid groove is threadedly connected with an outlet liquid joint. The inlet liquid joint and the outlet liquid joint are connected to an external circulating cooling source. A limiting circular plate is fixedly connected to the upper end of the connecting column. The limiting circular plate can control the insertion depth of the cooling device. A threaded column is fixedly connected to the upper end of the limiting circular plate. The cooling device is threadedly connected with a water tank in the core insert through the threaded column. A sealing groove is opened in the upper end of the limiting circular plate. A sealing ring is installed in the sealing groove. Extruding the sealing ring can achieve a sealing effect and prevent the coolant in the core insert from leaking out. The threaded column is threadedly connected with the core insert. A cooling column is fixedly installed at the upper end of the threaded column.

[0007] Preferably, a plurality of annular grooves are opened on the circumferential side of the operation column. The operator screws the cooling device into the core insert through the operation column. The annular grooves can increase the friction between the operator's hand and the operation column, facilitating the operator to install the cooling device.

[0008] Preferably, the liquid inlet groove and the liquid outlet groove do not penetrate the connecting column, and the liquid inlet groove and the liquid outlet groove are opposite to each other.
