Abstract
The invention discloses an injection molding machine which comprises an injection molding pipe provided with a feed port, a screw rod positioned in the injection molding pipe, an injection mold and a cooling water tank, wherein a plurality of convex blocks are uniformly arranged on an inner wall of the injection molding pipe; a heat preservation layer is arranged on the outer surface of the injection molding pipe; the injection molding pipe is connected with a strong heating electricity box and a weak heating electricity box; the cooling water tank is communicated with the injection mold mutually through a water inlet pipe and a water outlet pipe; and an air compressor is arranged on the water inlet pipe. The injection molding machine shortens the service time of a material pushing process, and improves the production efficiency of a product; the air compressor can provide high pressure to cooling water, to allow that no melt in the mold deforms easily in a cooling process; and the quality of the product is ensured.
Description
Technical field
The present invention is specifically related to a kind of injection machine.
Background technology
Injection machine is machinery very common during modern industry is produced, its principle is heated by plastic material, it is made to reach molten state, obtain the melt formed by plastic material, obtained melt injects in the middle of plastic mould by injection machine again, then hydraulic cylinder is utilized to drive mold to press down bed die, after pressing down end, bed die is cooled, corresponding plastic cement products can be obtained after cooling terminates, but the usual inwall of injection molding tube being used for melting plastic material in existing injection machine is very smooth, the screw rod being used for pushing plastic material is like this rotating in the process pushed, easy drive plastic material is round bolt rotary, make whole pusher process schedule quite slow like this, production efficiency also receives great impact, and the pressure be subject in the middle of mould due to melt is too small, melt is in cooling procedure, easy generation modification, have a strong impact on the Forming Quality of product.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, provide a kind of can improve plastic material pushing efficiency, prevent melt from the injection machine of modification occurring in mould.
Technical scheme: for achieving the above object, the invention provides a kind of injection machine, comprise the injection molding tube being provided with charging aperture, the screw rod being positioned at injection molding tube, injection mold and bosh, the inwall of described injection molding tube is provided with some projections uniformly, the outer surface of described injection molding tube is provided with heat-insulation layer, described injection molding tube is connected to forces thermoelectricity case and weak heating electronic box, described bosh and injection mold are interconnected by water inlet pipe and outlet pipe, and described water inlet pipe is provided with air compressor.
Preferably, described thermoelectricity case of forcing is positioned near injection molding tube discharge end, described weak heating electronic box is positioned near injection molding tube feed end, the temperature being arranged so that part being positioned at charging aperture in injection molding tube like this lower than the part being positioned at discharging opening, will avoid situation plastic material fusing too early in injection molding tube occurring and causes flowing out injection molding tube.
Preferably, described heat-insulation layer is heat insulating coatings, and heat insulating coatings has the effect of good heat-insulation and heat-preservation, effectively raises the utilization rate of heat energy, improves the efficiency of fusing.
Preferably, described screw rod is connected with hydraulically extensible motor, and hydraulically extensible motor can do commute motion by drive screw in injection molding tube.
Beneficial effect: the present invention compared with prior art, projection on injection molding tube inwall can increase the frictional force of plastic material and injection molding tube inwall, prevent plastic material to rotate around screw rod always, shorten the service time of pusher process, improve the production efficiency of product, air compressor can give cooling water high pressure, and make the melt in mould not easily modification occur in cooling procedure, the quality of product have also been obtained guarantee.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, the invention provides a kind of injection machine, comprise the injection molding tube 1 being provided with charging aperture 2, be positioned at the screw rod 3 of injection molding tube 1, injection mold 7 and bosh 9, the inwall of described injection molding tube 1 is provided with some projections 11 uniformly, the outer surface of described injection molding tube 1 is provided with heat-insulation layer 4, described injection molding tube 1 is connected to forces thermoelectricity case 5 and weak heating electronic box 6, described bosh 9 is interconnected by water inlet pipe 91 and outlet pipe 92 with injection mold 7, described water inlet pipe 91 is provided with air compressor 8, described thermoelectricity case 5 of forcing is positioned near injection molding tube 1 discharge end, described weak heating electronic box 6 is positioned near injection molding tube 1 feed end, described heat-insulation layer 4 is heat insulating coatings.
Specific works flow process of the present invention is: first start and force thermoelectricity case 5 and weak heating electronic box 6 pairs of injection molding tubes 1 carry out preheating, then plastic material is entered in injection molding tube 1 by charging aperture 2, start hydraulically extensible motor and make screw rod 3 movement back and forth in injection molding tube 1, plastic material is rolled move forward, in moving process, plastic material slowly melts under high temperature action, finally become melt, melt flows in injection mold 7, treat that melt is filled with injection mold 7, starting water pump makes the cooling water in bosh 9 enter water inlet pipe 91, air compressor 8 can give cooling water in water inlet pipe 91 enough pressure, cooling water flows into injection mold 7 pairs of injection molds 7 and cools, flow back to bosh 9 from outlet pipe 92 after cooling terminates to recycle.
