Abstract
The utility model provides an injection molding machine screw which comprises a feeding section, a compression section, a metering section and an extrusion section. The compression section and the metering section are located between the feeding section and the extrusion section, the metering section is connected with the extrusion section, a first concave portion is arranged on the portion, between every two screw threads, of the feeding section of the screw, a second concave portion is arranged on the portion, between every two screw threads, of the compression section of the screw, and the first concave portions and the second concave portions face the different directions. The injection molding machine screw is characterized in that the extrusion section comprises a mixing section, a threaded section and a head portion, wherein the mixing section is connected with the metering section, the head portion is in a cone shape, the threaded section is located between the mixing section and the head portion, and a mixer is fixedly connected on the mixing section. By means of the injection molding machine screw, plastic melts are scattered more evenly before injection, the color and luster of plastic products are more beautiful, material discharging is quick, coke charge can not happen easily, and quality of the products is greatly improved.
Description
Technical field
The utility model belongs to the injection molding apparatus field, relates in particular to a kind of injection machine parts.
Background technology
Screw rod is one of important parts of injection machine, it rotates in barrel, and with solid-state plastic particles or plastics powder fusion plastification, storage metering, carry, wherein plasticizing directly has influence on the quality of plastic products, during plasticizing, plastics are accepted the heat of barrel and the fricative heat melts of plastics and plastics, plastics and barrel, plastics and screw surface, and advance under the stirring of screw rod and finish injection moulding, so the structure of screw rod is extremely important.
In the existing injection machine, often there are the problems such as slow, the mixing inequality of blanking difficulty, material dispersion be bad, even burnt material when discharging, occurs, have a strong impact on the quality of plastic product.Chinese patent CN 201619231 U provide a kind of injection molding screw structure of injection molding, comprise pan feeding section, compression section and metering section, be provided with some the first depressed parts with screw rod direction of rotation fellow villager at the bar of screw rod pan feeding section, accelerated pan feeding, improved the blanking ability, screw rod in the compression section is provided with some second depressed parts reverse with the screw rod direction of rotation, make mixing even, can avoid simultaneously the generation of bubble and flow liner, plasticizing effect is increased, do not solve the plasticizing inequality that stirs and disperse to cause but, plasticizing effect remains further to be improved.
Summary of the invention
In order to address the above problem, the utility model is carried a kind of screw in injection molding machine, comprise feeding section, the compression section, metering section and extruding zone, described compression section and described metering section are between described feeding section and described extruding zone, described metering section links to each other with described extruding zone, be provided with the first depressed part at bar between each screw thread of described feeding section, be provided with the second depressed part at bar between each screw thread of described compression section, described the first depressed part and described the second depressed part towards the opposite, it is characterized in that: described extruding zone comprises the stirring section, thread segment and head, described stirring section links to each other with described metering section, described head is taper, described thread segment is fixedly connected with agitator in the stirring section between described stirring section and described head.
The screw thread of described thread segment is oblique screw thread.
Described agitator be shaped as curved leaf turbine type, the blade number is more than 2 or 2.
The beneficial effects of the utility model are: the increase of agitator, it is more even that plastic melt is disperseed before injection, can make the plastic products color and luster that injects more attractive in appearance, simultaneously can regulate mixing speed by the rotating speed of adjusting screw(rod), the setting of thread segment and head makes plastic melt extrude along hand of spiral, make the surface of product more smooth, and discharging is fast, be difficult for burnt material, can also stop to a certain extent the backflow of plastic melt, make product surface smooth, greatly improved the quality of product.
