Description

Novel double-screw exhaust type injection molding machine

Technical Field

The utility model relates to an injection molding machine exhaust technical field, concretely relates to novel double screw exhaust formula injection molding machine.

Background

The screw injection molding machine is one of the most widely used injection molding machine products at present, and during operation, granular or powdery plastic is generally added into a charging barrel, the plastic is made into a molten state by rotation of a screw in the charging barrel and heating of the charging barrel, and then the plastic is driven to move forwards by rotation of the screw, so that the plastic is ejected from a nozzle at a high pressure and speed, injected into a closed mold, and solidified into a required molded plastic product after pressure maintaining and cooling.

Part screw injection molding machine needs to set up desiccator or, leads to the cost to increase, causes the influence to production environment to the material nature stability is relatively poor after the raw materials is toasted the dehumidification processing.

Technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a novel double screw exhaust formula injection molding machine, includes feed cylinder, hydraulic system, moulds mechanism, front mould and back mould in advance, the inside of feed cylinder is equipped with the screw rod, gas vent and fixedly connected with sprue have been seted up at the top of feed cylinder, the inside fixedly connected with aiutage of gas vent, the exhaust hole has been seted up and has been inlayed two heating coils on the upper portion of aiutage surface, the top fixedly connected with gear motor of aiutage, gear motor's output runs through the top of aiutage and extends to the inside of aiutage, gear motor's little screw rod of output fixedly connected with, be equipped with between front mould and the back mould and move the mould, a side of moving the mould is equipped.

Furthermore, the screw comprises a feeding section, an exhaust section and a melting section, and the exhaust port is formed right above the exhaust section.

Furthermore, the top fixedly connected with of sprue deposits a feed cylinder, and a feed cylinder is the round platform form, is convenient for add the raw materials or save the raw materials through setting up a feed cylinder and deposits the raw materials.

Further, the one end fixedly connected with discharge gate of feed cylinder makes the raw materials of dehumidification stoving discharge through setting up the discharge gate and moulds plastics.

Compared with the prior art, this novel double-screw exhaust formula injection molding machine possesses following beneficial effect:

this novel twin-screw exhaust formula injection molding machine, throw into the raw materials to the inside of feed cylinder through the sprue, start gear motor drive little screw rod and carry out corotation, little screw rod downward compression is by the processing raw materials that the gas vent emits, the in-process at the compression raw materials produces gas and discharges through the exhaust hole, thereby realize the function to processing raw materials dehumidification, the drawback that current injection molding machine need dry by the fire the material at the in-process of processing has been solved to this structure, the spending of saving artifical material of drying by the fire and the power consumption that produces, more accord with the application and the popularization in market.
