Injection molding machine

Abstract

The invention provides an injection molding machine, comprising a station, a die which is arranged on the station and provided with a main runner gate, an injection device with a feeding rod and a gas filter system; the gas filter system comprises a hollow gas collecting box which is arranged on the station of the injection molding machine; the hollow gas collecting box is used for collecting the gas exhausted by the injection forming machine; the injection molding machine also comprises at least an air guiding pipe which is communicated with the hollow gas collecting box, at least an air drawing device which is connected with the air guiding pipe and used for pumping the gas inside the hollow gas collecting box, and at least a filter which is communicated with the air guiding pipe and arranged between the hollow gas collecting box and the air drawing device, and used for filtrating the gas inside the hollow gas collecting box.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to an injection molding machine using a gas filtering system. Background technique [0002] With the development of modern industry, the application of injection molding technology is becoming more and more widespread (please refer to the article titled "Development Status and Prospects of Micro-injection Molding Technology" published by Wang Leigang in the first issue of "Modern Plastic Processing Application" in 2007) . [0003] The injection molding machine will generate toxic gas during injection molding, especially when cleaning up the waste left in the feeding screw, the amount of toxic gas generated is relatively large. Generally, the injection molding machine is not equipped with any toxic gas collection device, which is toxic The gas will be scattered in the workshop, and the toxic gas can only be extracted out of the workshop by the exhaust system installed on the ceiling o...

[0003] The injection molding machine will generate toxic gas during injection molding, especially when cleaning up the waste left in the feeding screw, the amount of toxic gas generated is relatively large. Generally, the injection molding machine is not equipped with any toxic gas collection device, which is toxic The gas will be scattered in the workshop, and the toxic gas can only be extracted out of the workshop by the exhaust system installed on the ceiling of the workshop. However, it is relatively difficult to extract all the toxic gases that volatilize in the entire workshop

In addition, when cleaning the waste of the injection molding machine, the toxic gas generated by the waste remaining in the feeding screw volatilizes to the whole workshop at high temperature. Generally, the exhaust system on the ceiling has no time to pump out these toxic gases, so it is not only harmful to the work Hazard to the health of personnel and pollution to the environment
