Injection punch cooling device of horizontal cold chamber die casting machine

The utility model relates to the technical field of injection punch cooling, and discloses a horizontal cold chamber die casting machine injection punch cooling device which comprises a mounting plate, a connecting block is fixedly connected to the side face of the mounting plate, an annular water cooling bin is fixedly connected to one end of the connecting block, and an injection punch body is arranged in the annular water cooling bin. The injection punch cooling device of the horizontal cold chamber die casting machine effectively solves the problems that in the actual use process, when an existing injection punch is used, a cooling water pipeline is fixedly connected with an external water cooling chamber of the punch, so that the injection punch used for a long time in the device cannot be conveniently detached and replaced, and the service life of the injection punch is prolonged. According to the cooling device for the injection punch of the die-casting machine, the problem that an existing injection p
