technical field [0001] The invention relates to the field of injection molding machines, in particular to an auxiliary heat dissipation device for an injection molding machine melt glue driving mechanism. Background technique [0002] The drive mechanism for the melt structure of the injection molding machine is mainly used to provide rotational power to the plasticizing screw to perform the melt action. At present, the current melt structure of the injection molding machine is mainly composed of a drive mechanism composed of a motor and a reducer for feeding the plastic. The rotary screw provides the rotational driving force. Based on the special use of the injection molding machine itself, the extrusion thrust is large during use, which will cause the temperature in the motor and the reducer to rise sharply.

Problems solved by technology

Based on the special use of the injection molding machine itself, the extrusion thrust is large during use, which will cause the temperature in the motor and reducer to rise sharply. At present, these heat mainly rely on the motor housing and reducer housing for self-radiation. The heat dissipation efficiency is low, and the heat cannot be dissipated in time and quickly, which will seriously affect the service life of the motor and reducer

In order to help the driving mechanism to dissipate heat quickly, the conventional method is to use air blowing to cool the outside of the driving mechanism. However, during the production process of the injection molding machine, powdery materials may enter the interior of the injection molding machine through the feeding port, and the blowing method is used. Auxiliary heat dissipation treatment is carried out on the driving mechanism. When the powdery material is added, it is easy to form dust, which not only causes waste of material, but also affects the entire production environment, which is not conducive to the health of the operator.
