Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a head cooling device for injection molding machines. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The working principle of the injection molding machine is similar to that of a syringe for injections. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (i.e., viscous flow state) plastic into the closed mold cavity, and obtain the product after solidification and shaping.

[0003] After searching, it was found that the publication number is CN213291244U, and the name is a cooling device for an injection molding machine head. The application proposes that the temperature of the injection molding machine head is high during operation. When the work is finished, the temperature is difficult to drop quickly, which affects the working life of the head. A cooling pipe is arranged on the outer wall of the injection molding machine head body, and the cooling pipe is connected to the cooling water tank. The cooling water in the cooling water tank enters the cooling pipe through the external water inlet pipe, and then returns to the cooling water tank through the external water pipe. Cooling water is circulated in the cooling pipe to exchange heat with the injection molding machine head body and accelerate its cooling. However, in the cooling process of the application, the low temperature of the cooling water needs to be first transmitted to the cooling pipe, and then transmitted to the injection molding machine head body by the cooling pipe. Two heat conductions need to be completed, which will lose the energy of the cooling water, resulting in a decrease in cooling efficiency and affecting the cooling effect. Further improvements can be made. At the same time, once the cooling pipe is blocked, it needs to be disassembled and dredged as a whole, which is very troublesome and inconvenient to disassemble and maintain. Further improvements can also be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
