Abstract
The utility model relates to an injection machine charging spout with a venting means, the outer wall of the charging spout is provided with heat generation resistance, the charging spout is provided with a charging screw, the upper part of the charging spout is provided with a charging hopper, the head part of the charging spout is provided with a nozzle, and the upper part of the charging spout between the charging hopper and the nozzle is provided with a louver. The charging spout of the utility model is provided with the louver, and water content of plastic raw materials in the charging spout can be heated with advancing the screw to generate bubbles; the bubbles can be discharged through the louver, particularly can be sucked out of a vacuum pump; the bubbles can not be inserted into products, and the plastic raw materials can not be baked before injection; the injection machine charging spout with the venting means has the advantages of energy saving, process reducing, man-hours shortening, and low cost.
Description
The utility model relates to the parts in the injection machine, particularly relates to the improvement design of injecting machine material tube.
In the plastics injection technique, the plastic raw materials big to water absorption rate, for example: ABS, nylon, lucite, PET polyester etc., need dry and do pre-treatment, can produce, otherwise shaped article can entrained air bubbles in injection, cause consequences such as product quality is defective.Not only increase operation and adopt special equipment that plastic raw materials is dried, and consumed power, the time is long, needs baking 5-6 hour as the PET polyester under 160 ℃ of conditions, can produce.Therefore, the barrel of existing injection machine does not possess dehumidification function, has structural defective.
The purpose of this utility model is in order to overcome the defective of prior art, to provide a kind of in heating, the injecting machine material tube of the exhaust that can dehumidify.
The technical scheme that the utility model is shaped on the injecting machine material tube of exhaust apparatus is: the outer wall at barrel is installed heating resistor, is furnished with feeding spiro rod in the barrel, hopper is installed in the top of barrel, and the head of barrel has nozzle, it is characterized in that the system transom window is left in the barrel top between hopper and the nozzle.
The utility model is shaped on the injecting machine material tube of exhaust apparatus, and the transom window of its barrel top connects vavuum pump.
The utility model is shaped on the injecting machine material tube of exhaust apparatus, at blueline of preposition setting of transom window, to being a district between the blueline, is two districts from hopper from blueline to screw head, and the screw channel volume in two districts is greater than the screw channel volume in a district.
The utility model discloses a kind of injecting machine material tube that is shaped on exhaust apparatus, compared with the prior art, have following characteristics; Above barrel, drive the system transom window, after plastic raw materials enters the screw channel of screw rod from hopper, along with screw rod rotation raw material is heated in advancing, moisture content in the raw material produces steam, after steam gas arrives the transom window mouth, discharges barrel, particularly, avoid bubble is injected product by the vavuum pump sucking-off.If at the blueline of delimiting hypothesis near the position of transom window, hopper is to being a district between the blueline, the screw channel volume in one district is smaller relatively, and at blueline to being two districts between the screw head, the volume of two district's screw channels is big relatively, capacious interval feeding is fast, avoids raw material to discharge in company with gas in transom window like this.Transom window has been arranged, can need not dry, saved power consumption, reduced operation, shortened process time, saved cost plastic raw materials.
Fig. 1 is the injecting machine material tube assembly schematic diagram that the utility model is shaped on exhaust apparatus.
Below in conjunction with Fig. 1 embodiment of the present utility model is done detailed explanation.
The utility model relates to the improvement design of injecting machine material tube, plastic raw materials is in injection processing, if moisture content height, in barrel, can produce bubble after the heating, if will just influence quality in the bubble injected plastic product, even scrap, therefore to plastic raw materials such as ABS, nylon, PET polyester, all to dry pre-treatment.According to the injecting machine material tube modular construction, at the outer wall of barrel 2 heating resistors 7 such as heating wire are installed, be furnished with feeding spiro rod 3 in the barrel, hopper 1 is installed in the top of barrel, and the head of barrel has nozzle 8.After screw rod 3 screw channels 13 of plastic raw materials in hopper 1 enters barrel 2, along with screw rod 3 rotations are advanced, when advancing, heated by heating resistor 7, also can produce the steam bubble.In order to overcome the prior art defective, avoid bubble is injected product, above barrel 2, drive system transom window 4 (being macropore), bubble is discharged from transom window, in order to ensure exhaust, transom window 4 is connected vavuum pump 5, aspirate by vavuum pump.For fear of when bubble is discharged, with the plastic raw materials sucking-off from transom window after the heating, can be to whole barrel 2 and screw rod 3 subregions, blueline 10 is before transom window 4, as shown in Figure 1, screw channel 13 volumes in the Jiang Yi district 11 are smaller, and charging rate is just slow relatively, big to screw channel 6 volumes in two districts 9, charging rate is fast relatively.The size of this screw channel volume can be realized by groove depth or groove width.
