Description
канал 8 штока 5 в момент раскрыти нрессформы и начала выталкивани пресс-остатка из литниковой втулки 3. Смазка, наход нда с во внутреннем канале 8 uiTOKa 5, не возвращаетс через гибкий шланг 11 благодар обратному клапану в штуцере 12, а распыливаетс в виде масл ного тумана через выпускные отверсти 9. Распыление смазки производитс на внутреннюю поверхность литниковой втулки 3 и камеры прессовани 1 непрерывно до возвращени выпускных отверстий 9 к заливочному окну 2 нри обратном ходе щтока 5 с порн1нсм 4. Когда поршень 4 со штоком 5 наход тс в крайнем переднем (левом) положении (фиг. 2), смазка попадает на всю виутреннюю поверхность литниковой втулки 3 благодар кольцевому зазору между поришем 4 и литниковой втулкой, образоваиному выточ ()й о по диаметру на 4 и конусом 15 на литниковой втулке 3. В это врем происходит смазывание и поршн 4. Смазывание поршн происходит и во врем обратного хода его со игтоком 5.the channel 8 of the rod 5 at the time of opening the mold and starting to push the press residue out of the gate sleeve 3. The lubricant, located in the internal channel 8 uiTOKa 5, does not return through the flexible hose 11 due to the non-return valve in the nozzle 12, but is sprayed as an oil mist through the outlets 9. The lubricant is sprayed onto the inner surface of the sprue bushing 3 and the pressing chamber 1 continuously until the outlets 9 return to the filling window 2 when the piston 5 is retracted 5 seconds 1 when the piston 4 is out in the extreme front (left) position (Fig. 2), the lubricant falls on the entire interior surface of the sprue bushing 3 due to the annular gap between the porce 4 and the sprue bushing, the undercut () is about the diameter of 4 and the cone 15 on the bushing 3. At this time, the lubrication of the piston 4 also occurs. The lubrication of the piston also occurs during its return stroke with the needle bar 5.
Изобретение обеспечивает полное смазывание внутренних поверхностей литниковой втулки и камеры прессовани .The invention provides full lubrication of the inner surfaces of the sprue bushing and the extrusion chamber.
