Abstract

The invention discloses an injection device of a precision injection machine, and relates to the field of precision injection machines. The injection device of the precision injection machine comprises a sliding rail, a base, a base driving device, an injection pipe, a heating sleeve, a material feeding hopper, a screw rod, a shaft coupler, a screw rod driving device, a sliding seat and a sliding seat driving device. During material feeding and injection, counter-acting force on the screw rod is directly transmitted to the sliding seat through a convex ring and a large bearing, and is finally borne by the sliding seat driving device for injecting a material, so that the screw rod driving device only supplies rotating torque during use and not bears the axial pressure; therefore, the screw rod driving device is effectively protected, and the low-power screw rod driving device with lower energy consumption and smaller size is adopted according to the space requirement of a laboratory; and furthermore, an additionally arranged heat isolation hood can effectively avoid accidental scalding of an operator during material machining, so that the injection device is extremely high in use safety and reliability.

Description

technical field [0001] The invention relates to the field of precision injection molding machines, in particular to the improvement of the injection device therein. Background technique [0002] At present, at present, most of the precision injection molding machines on the market are for the purpose of processing and production, and most of them have the characteristics of large energy consumption, high output, and large floor area. It is a Chinese patent document for "Miniature Precision Injection Molding Machine" with application number "201110360618.5". In this case, a technical solution is proposed to shorten the length of the injection molding machine and make its structure more compact. [0003] However, due to the limited space in most laboratories at present, the energy consumption and expenditure are not high; therefore, the driving devices and transmission structures used in the above technical solutions to ensure the clamping force and injection pressure cannot b...
