Cooling device of plastic injection molding machine

Abstract

The invention provides a cooling device for a plastic injection molding machine. Temperature sensors are arranged on both sides of the feed hopper. A surrounding horizontal cooling pipe and a vertical cooling pipe are arranged in the body of the cooling device. One side is provided with a water inlet, one side of the longitudinal cooling pipe is provided with a water outlet, and the middle of the surrounding horizontal cooling pipe and the longitudinal cooling pipe is provided with a main cooling fan, and the two sides of the main cooling fan are provided with temperature For the controller, several cooling fins are arranged around the main cooling fan, and a secondary cooling fan is arranged at the lower part of the cooling device body. The beneficial effect of the present invention is that the cooling device of the injection molding machine is equipped with a main cooling fan, and the cooling temperature is transmitted through the cooling fins, and the water circulation of the horizontal and vertical cooling pipes is used for cooling, effectively avoiding plastic particles during the feeding process. Agglomeration occurs due to the absorption of a large amount of heat, which ensures the feeding speed and improves the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of injection molding machine equipment, and in particular relates to a cooling device for a plastic injection molding machine. Background technique [0002] Plastic injection molding machines are widely used in the mold industry. Now plastics are more and more widely used, and plastics have good chemical stability and strong resistance to weak acids and weak alkalis. The development of the plastics industry has driven the widespread use of plastic injection molding machines. [0003] During the operation of the injection molding machine, the general hopper is installed on the barrel assembly. The barrel assembly is provided with a heating ring, and a cooling device is provided next to the discharge port of the barrel, which can make the plastic inside the hopper The particles can be smoothly added into the barrel, but the cooling effect of the cooling device is not obvious. During the feeding process, the pl...

[0003] During the operation of the injection molding machine, the general hopper is installed on the barrel assembly. The barrel assembly is provided with a heating ring, and a cooling device is provided next to the discharge port of the barrel, which can make the plastic inside the hopper The particles can be smoothly added into the barrel, but the cooling effect of the cooling device is not obvious. During the feeding process, the plastic particles will agglomerate due to a large amount of heat, which will block the feeding port. The cooling device is very important for the feeding port. The plastic particles in the place are not cooled uniformly, which reduces the feeding speed and affects the actual production efficiency
