High-efficiency injection molding machine

Abstract

The invention relates to the technical field of injection molding machines, and specifically relates to a high-efficiency injection molding machine comprising an injection molding machine body. A motor assembly is fixedly installed on the right side of the upper end of the injection molding machine body, an injection molding pipeline is fixedly installed on the left side of the motor assembly, and a first threaded rod movably connected with the motor assembly is rotatably inserted into the injection molding pipeline. A hopper is fixedly arranged at the position, close to one side of the motor assembly, of the upper end of the injection molding pipeline, a drying mechanism is fixedly arranged in the hopper, an exhaust mechanism is fixedly arranged in the middle of the upper end of the injection molding pipeline, and a heating plate is fixedly installed on the left side of the outer wall of the injection molding pipeline. By arranging the drying mechanism, PMMA plastic can be dried during feeding. The dried PMMA plastic can be directly used, drying air can be recycled, loss of the drying plate is reduced, the cost can be effectively reduced, the PMMA plastic injection molding quality is also improved, and the ventilation effect of the drying mechanism can be guaranteed under the cooperation of a cleaning mechanism.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a high-efficiency injection molding machine. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. When PMMA plastic is injected, because PMMA plastic has certain water absorption, its water absorption rate reaches 0.3-0.4%, and the temperature of injection molding must be below 0.1%, usually 0.04%. The presence of moisture will cause bubbles or air marks in the melt, and reduce the transparency. Therefore, the PMMA plastic should be dried before injecti...

AI Technical Summary

Problems solved by technology

As a result, the estimation accuracy of the usable period of the advancing and retreating mechanism can be improved, but in the process of actual use, because PMMA plastic has water absorption, only improving the estimation accuracy of the advancing and retreating mechanism cannot improve the quality of the injection molded product. Bubbles or air marks are generated due to the presence of moisture, resulting in poor quality of PMMA plastic injection molding products
