A circulating injection molding machine

Abstract

The invention discloses a circulating injection molding machine. The circulating injection molding machine comprises a main body shell, a plastic containing groove is formed in the top of one side ofthe main body shell, a main longitudinal flowing hole is formed in the bottom of the plastic containing groove, a funnel space is formed in the bottom of the main longitudinal flowing hole, and an auxiliary longitudinal flowing hole is formed in the bottom of the funnel space; and the main body shell is provided with an eddy current heating mechanism on the annular side surface of the auxiliary longitudinal flow hole, and the bottom of the auxiliary longitudinal flow hole is provided with a transverse plastic feeding hole. According to the circulating injection molding machine, normal raw material melting and injection functions can be achieved, when raw material injection needs to be delayed due to external factors, molten plastic can flow in an internal circulation mode through the raw material pushing effect of a screw rod, and the molten plastic flows back into the eddy current heating mechanism again and is heated and molten again, so that the melting degree is improved, the plastic shaping trend caused by static time is effectively prevented, the quality of molten plastic is improved, and thus the final shaping quality is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a circulating injection molding machine. Background technique [0002] At present, when the existing injection molding machine is inputting raw materials, it needs to wait for the raw materials to wait until the raw materials are shaped before proceeding to the next raw material injection. However, due to the waiting time, the melted raw materials inside have a certain cooling and shaping tendency. , resulting in lower raw material quality next time. Contents of the invention [0003] The object of the present invention is to provide a circulating injection molding machine to solve the problems raised in the background art above. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a circulating injection molding machine, comprising a main body housing with support legs installed at the bottom, a pl...
