Description
(54) УСТРОЙСТВО ДЛЯ ПРОДУВКИ ПРЕС(:-ФОР. г.:ю(54) DEVICE FOR PRESS BLOWING (: - FOR. G.: Y
II
Изобретение относитс к литейному производству , в частности к литью металлов под давлением.The invention relates to foundry, in particular to the casting of metals under pressure.
По основному авт. св. № 461796 известно устройство дл продувки пресс-форм, используемое при литье металлов на машинах лить иод давлением. Устройство выполнено в виде подпружиненной муфты со штуцером, св занной с источником сжатого газа и подвижно установленной +ia наполнительном стакане, закрепленном в передней стойке машины лить под давлением.According to the main author. St. No. 461796, a device for blowing molds is known, which is used in metal casting on injection molding machines. The device is made in the form of a spring-loaded coupling with a fitting connected to a source of compressed gas and a movably mounted + ia filling glass fixed in the front pillar of the machine to be cast under pressure.
Недостаткс м этого устройства вл етс то, что муфта может проворачиватьс относительно наполнительного стакана, что приводит к сменамппо заливочных окон и разбрызгиванию за,1иваемого металла. Кроме того, возможно заклинивание пружины при попадании на нее брызг металла.The disadvantage of this device is that the clutch can rotate relative to the filling cup, which leads to a smashing filling window and splashing out of the metal. In addition, it is possible seizure of the spring when metal splashes hit it.
Цель изобретени повышение надежности и безонаспости работы устройства.The purpose of the invention is to improve the reliability and safety of the device.
Цель достигаетс гем, что устройство снабжено запи1тным кожухом, охватывающим пружину, причем на внутренней поверхности муфты iibii o,;iii4i продольный паз, а на наполнительном стакане - выступ, взаимодейств Ю1ций с пазом.The goal is to achieve that the device is equipped with a memory cover covering the spring, with a longitudinal groove on the inner surface of the iibii o,; iii4i coupling, and a protrusion on the filling glass, interacting with the groove.
На фиг. 1 и 2 изображено предлагаемое устройство.FIG. 1 and 2 shows the proposed device.
На нанолните.чьном стакане 1 подвижпо установлена муфта 2 с продольным пазом 3, в который входит выстуи 4, выполненный на наполнительном стакане. Пружина 5 зашишена цилиндрическим кожухом 6, закрепленным на передней стойке 7 мапшны лить под давлением.On a nanolite, a glass 1 slider, a clutch 2 is installed with a longitudinal groove 3, which includes the curve 4, made on a filling glass. The spring 5 is encased with a cylindrical casing 6 fixed on the front pillar 7 of the molding machine under pressure.
При действии сил. поворачивающих муфту 2, выступ 4 компенсирует их действие, и заливочные окна нанолнительного стакана I и муфты 2 всегда совпадают после прекран1ени подачи сжатого газа.Under the action of forces. turning coupling 2, the protrusion 4 compensates for their action, and the filling windows of the filling glass I and coupling 2 always coincide after stopping the supply of compressed gas.
Описываемое устройство обеспечивает надежность и безонасность работы, так как предотвращаютс разбрызгивание расн,1авленного металла за счет совпадени заливочных окон муфты и наполните.-п.ного стакана и заклинивание пружины.The described device ensures reliability and safety-free operation, since spattering of the molten metal is prevented due to coincidence of the filling windows of the coupling and filling the filling glass and spring jamming.
