Description
Technical field
The utility model relates to injection-moulding device art, particularly relates to a kind of vacuum dehumidifying injection machine.
Background technology
In the production process of plastic products, aqueous vapor in various degree can be produced, the materials such as escaping gas, when these materials can not timely and effective discharge time, bubble will be showed, moire, the problems such as crackle spot, therefore, all dry process in advance must be carried out by external drying machine for the plastic material that will carry out injection moulding production, and traditional drying machine is all carry out heating barbecue by hot blast and discharged by moisture, therefore need to consume a large amount of time and electric power resource, cause the increase of production cost, also economize energy and environmental protection is unfavorable for, simultaneously, because the time of drying is longer, the time of carrying out the wait of injection moulding need of production is also longer, be unfavorable for the production efficiency improving injection moulding production.
Utility model content
The utility model, for the disappearance of prior art existence, provides a kind of vacuum dehumidifying injection machine without the need to being carried out heat drying in advance to raw material by external drying machine.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
A kind of vacuum dehumidifying injection machine, comprise screw rod, main barrel and feed hopper, described screw rod is arranged in main barrel, described inside screw is provided with heater, described main barrel is provided with interconnective charging and plasticizing zone and injection zone, described feed hopper comprises transition hopper setting up and down and vacuum hopper, the upper end of described transition hopper is provided with the feeding vacuum valve controlling to enter from outside feeding in transition hopper, lower end is provided with the charging vacuum valve controlling to enter vacuum hopper from transition hopper feeding, described vacuum hopper is arranged at the top of main barrel charging and plasticizing zone, bottom is provided with the charging aperture be communicated with main barrel, side is provided with exhaust outlet, described exhaust outlet pipe connects vacuum extractor.
As a kind of preferred version, be provided with the first cylinder between described transition hopper and vacuum hopper, the opening and closing of described first air cylinder driven charging vacuum valve, the upper end of described transition hopper is provided with the second cylinder, the opening and closing of described second air cylinder driven feeding vacuum valve.
As a kind of preferred version, described main barrel is positioned at the perforation that charging and plasticizing zone one end have an axis, and described screw rod stretches in main barrel through this perforation, and is in transmission connection with driven unit, and the junction of described screw rod and perforation is provided with hermetically-sealed construction.
As a kind of preferred version, described hermetically-sealed construction comprises a sealing ring and pressing plate, is affixed on the junction of aforementioned screw rod and perforation inside described sealing ring, and described pressing plate is pressed on outside sealing ring.
Compared with prior art the utility model has obvious advantage and beneficial effect, specifically, by setting gradually vacuum hopper and transition hopper above main barrel, and charging vacuum valve and feeding vacuum valve are set respectively in the upper end of vacuum hopper and transition hopper, by the dual sealing of charging vacuum valve and the true valve of feeding, improve the sealing effectiveness of main barrel, and then improve the quality that vacuum extractor vacuumizes main barrel.Vacuum extractor is provided with exhaust outlet by the side opening of vacuum hopper and screw rod is heated aqueous vapor that plastic material produces and escaping gas is discharged outside injection machine, avoid aqueous vapor and the quality of escaping gas to plastic products has an impact, thus without the need to carrying out pretreatment by drying machine, simplify the program that injection moulding is produced, save the stand-by period that injection moulding is produced, reduce production cost, improve production efficiency, reach energy-conservation object.
