Известно устройство дл пластикации и впрыска полимерных материалов, содержащее пластикационный цилиндр с бункером, расположенный в пластикационном цилиндре шнек, соединенный с П|ри1водом его вращени и корпусами гидроцилиндров впрыска, размещенных симметрично относительно шнека и выполненных с двусторонними штоками, один конец которых жестко соединен с пластикационным цилиндром, и неподвижную плиту.A device for plasticization and injection of polymeric materials is known, comprising a plasticizing cylinder with a hopper, a screw located in the plasticizing cylinder, connected to a P | rider of its rotation and injection cylinder cylinders arranged symmetrically with respect to the screw and made with double-sided rods, one end of which is rigidly connected to the plasticizing cylinder, and fixed plate.
Нед0:статком известного устройства вл етс мала надежность в работе из-за возможности перекоса подвижных частей устройства.Ned0: The standard of the known device is low reliability in operation due to the possibility of skewing the moving parts of the device.
Цель изобретепи - исключение перекосов дл повышени надежности в работе. Указанна цель достигаетс тем, что второй конец каждого двустороннего штока установлен с возможностью осевого неремещени в выполнеиной в неподвижной плите расточке.The purpose of the invention is to eliminate distortions in order to increase operational reliability. This goal is achieved by the fact that the second end of each double-sided stem is installed with the possibility of axial non-displacement in the bore in the fixed plate.
Устройство дл пластикации и в прьгока показано на фиг. 1 и 2.The device for kneading and piercing is shown in FIG. 1 and 2.
Устройство содержит пластикационный цилиндр I с бункером 2, шнек 3, соединенный € гидродБигателсм 4 и корпусами 5 гидроцилиндров впрыска с расположенными в них двустороиЕими штоками 6, и неподвижную плиту 7. Один конец 8 двусторонних штоков 6 жестко соединен гайками 9 с пластикационным цилиндром 1, а второй конец 10 установлен в расточке 11 неподвижной плиты с возможностью осевого перемещени .The device contains a plasticizing cylinder I with a hopper 2, a screw 3, connected with hydraulic Big 4 and bodies of 5 injection cylinders with double sided rods 6 located in them, and a fixed plate 7. One end of 8 bilateral stems 6 is rigidly connected with nuts 9 with plasticizing cylinder 1, and the second end 10 is mounted in the bore 11 of the fixed plate with the possibility of axial movement.
Работа устройства осуществл етс следующим образом.The operation of the device is as follows.
Гидродвигатель 4 вращает шнек 3, осуществл ющий пластикацию полимерного материала , поступающего из бункера 2. По мере накоплени материала в пластикационном цилиндре 1 щнек отжимаетс в осевом направлении и отводит соединенные с ним корпуса 5 гидроцилиндров впрыска. По окончании набора порции материала вращение шнека 3 гидродвигателем 4 прекращаетс , подаетс давление в полость а гидроцилиндров впрыска , производитс впрыск щнеком материала в форму. При этом второй конец 10 двустороннего щтока 6 перемещаетс в расточке И неподвижной плиты вследствие раст жени двустороннего щтока усилием впрыска.The hydraulic motor 4 rotates the screw 3, which makes the plasticization of the polymer material coming from the bunker 2. As the material accumulates in the plasticizing cylinder 1, the jaws are pressed in the axial direction and retracts the injection cylinder bodies 5 connected to it. At the end of the set of portions of the material, the rotation of the screw 3 by the hydraulic motor 4 is stopped, pressure is applied to the cavity and the hydraulic cylinders of the injection are injected with a material screw into the mold. In this case, the second end 10 of the double-sided shaft 6 is moved in the bore And the stationary plate due to the expansion of the double-sided shaft by the injection force.
При необходимости принудительного отвода щнека 3 давление рабочей жидкости подаетс в полость б гидроцилиндров впрыска.If necessary, the forced removal of the screw 3, the pressure of the working fluid is fed into the cavity of the hydraulic cylinders of injection.
