Problems solved by technology

[0003] In the pre-order work of injection molding, thermoplastic particles may be bonded together due to humidity, so that during the process of melting the particles, some moisture may be included in the melted product, which will affect the quality of the injection molded product. At the same time, When the particles bonded together are large, it will block the discharge port of the hopper, which may cause the machine to stop running and cause economic losses

Abstract

The invention relates to the field of injection molding machines, in particular to a circulating stirring type injection molding machine pressurizing hopper. The circulating stirring type injection molding machine pressurizing hopper comprises a machine body, wherein a drum is installed on the left side of the interior of the machine body; a spiral blade used for conveying materials rightwards isinstalled on the drum; stirring teeth are installed on the spiral blade; a first driving mechanism used for driving the drum to rotate is installed at the left end of the machine body; a plurality ofstirring assemblies are further circumferentially distributed and installed on the right side of the drum in the machine body; a second driving mechanism used for driving the stirring assemblies to rotate is installed at the right end of the machine body; a pressurizing assembly used for pressurizing the inner cavity of the machine body through the drum is further installed on the left side of themachine body; a circulating conveying assembly used for conveying materials at the bottom of the right end of the inner cavity of the machine body to the top of the left end of the inner cavity of the machine body is further installed on the outer side of the machine body; and a heating cylinder is further embedded in the inner cavity wall of the machine body. The circulating stirring type injection molding machine pressurizing hopper is novel in structure, capable of conveying and stirring materials, good in mixing effect and beneficial to material discharge.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a pressurized hopper of a circulating stirring type injection molding machine. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main equipment for plastic injection molding. The injection molding machine converts thermoplastics from granular resins into molded products through a cycle of melting, injection, pressure holding, and cooling. [0003] In the pre-order work of injection molding, thermoplastic particles may be bonded together due to humidity, so that during the process of melting the particles, some moisture may be included in the melted product, which will affect the quality of the injection molded product. At the same time, When the particles bonded together are large, it will block the discharge port of the hopper, which may cause the suspension of machine operation and cause econo...
