Abstract

The invention discloses an injection molding machine hopper preheating device which comprises a guide bin. The lower portion of the guide bin is provided with a discharge bin. The end of the guide bin is provided with a feeding opening. The lower end of the discharge bin is provided with a discharge opening. Inner side positions of the guide bin are provided with electric heating plates. Outer side positions of the discharge bin are provided with fixing plates. The fixing plates are provided with temperature controllers. The temperature controllers are connected with the electric heating plates through cables. The fixing plates are provided with side frames. The inner sides of the side frames are provided with limiting plates. A butt connection ring is arranged between the tops of the limiting plates. A guide shell is arranged between the limiting plates. An inserting plate is inserted and connected to the side position of the guide shell. Outer sides of the inserting plate are provided with pull shafts. Pull pipes are arranged on the outer circumferential faces of the pull shafts. An operation pipe is arranged between the upper portions of the pull pipes. A butt connection pipe is arranged between the middles of the operation pipes. A pull wheel is arranged in the middle of the butt connection pipe. The interior of the guide bin can be controlled to be electrically heated, plastic granules can be poured into the guide bin, and the plastic granules can be electrically heated.

Description

Technical field [0001] The invention relates to a preheating device, in particular to a preheating device for a hopper of an injection molding machine. Background technique [0002] The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw to inject the plasticized and molten plastic into the closed mold cavity, and obtain the product after solidification and shaping. The function of the hydraulic transmission system is to realize the injection molding machine to provide power according to the various actions required by the process, and to meet the requirements of the pressure, speed, temperature, etc. required by each part of the injection molding machine. It is mainly composed of various hydraulic components and hydraulic auxiliary components, among which the oil pump and the motor are the power source of the injection molding machine. Various valves control the oil pressure and flow rate to meet the ...
