Description

Изобретение относитс  к строительству , может быть использовано дл  изготовлени  пустотелых изделий и  вл етс  усовершенствованием устройства по авт.св. № 557919.The invention relates to the construction, can be used for the manufacture of hollow products and is an improvement of the device according to ed. No. 557919.

Цель изобретени  - повышение производительности и надежности устройства в работе за счет исключени  заклинивани  пустотообразователей и снижени  действующего на их привод усили .The purpose of the invention is to improve the performance and reliability of the device in operation by eliminating the jamming of the hollow cores and reducing the force acting on them.

На фиг.1 изображено предлагаемое устройство, установленное на прессе, продольный разрез; на фиг.2 - узел Т на фиг.1.Figure 1 shows the proposed device installed on the press, a longitudinal section; figure 2 - node T in figure 1.

. Устройство содержит обойму 1 с полыми пустотообразовател ми 2, подвижно закрепленную в направл ю щих 3. Наклонна  поверхность рабочего торца пустотообразовател  расположена под углом 23-34 к его продольной оси. В контрштампе 4 выполнены отверсти . Отношение площади .проходного сечени  отверсти  в контрштампе на входе пустотообразовател  к соответствующей площади на выходе пустотообразовател  составл ет 1,06-1,18. Обойма 1 штоком 5 соединена с приводом (не показан), перемещающим ее вдоль направл ющих 3.. The device contains a holder 1 with hollow holders 2, which is movably fixed in guides 3. The inclined surface of the working end of the hollow generator is located at an angle of 23-34 to its longitudinal axis. In the counter-stamp 4 holes are made. The ratio of the area of the passage section of the hole in the counter stamp at the inlet of the core former to the corresponding area on the outlet of the core former is 1.06-1.18. The yoke 1 is connected to a drive 5 with a drive (not shown) moving it along the guides 3.

Устройство работает следующим образом .The device works as follows.

Стол 6, несущий заполненные формовочной смесью пресс-форм 1 6, останавливаетс  над прессующим поршнем 8The table 6 carrying molds 1 6 filled with molding sand is stopped above the pressing piston 8

срабатывает привод, и обойма 1, толкаема  штоком 5, вводит в пресс-форму 7 пустотообразователи 2. Формовочна  смесь заполн ет нижнюю часть их 5 массопровод щей полости. Затем поднимаетс  штамп 9, толкаемый поршнем 8. Формовочна  смесь в пресс-форме 7 уплотн етс , а в полости пустот ообра- зователей 2 проталкиваетс  вверх. По окончании операции прессовани  привод поднимает обойму 1 с пустотообразовател ми и заключенной в их полости формовочной смесью. Благодар  выполнению отверстий в контрштампе с расширением исключаетс  возможность заклинивани  пустотообразователей, так как формовочна  смесь, увлекаема  пустотообразовател ми в зазор между стенками отверстий в контрштампе и 2Q внешней поверхностью пустотообразователей , попадает в обойму и затем удал етс  с помощью специальных лотков (не показаны). Далее опрессован- ное изделие извлекаетс  из пресс-формы 7 и снимаетс  со стола 6. Расположение наклонной поверхности рабочего пустотообразовател  под углом 23-34 ° к его продольной оси позвол ет уменьшить сопротивление формовочной смеси пустотообразовател1 м при погружении в пресс-форму и, следовательно , снизить усилие, действующее . на привод.the actuator operates, and the yoke 1, pushed by the stem 5, inserts into the mold 7 the holders 2. The molding mixture fills the lower part of their 5 mass-conducting cavity. Then, the punch 9 is raised, pushed by the piston 8. The molding mixture in the mold 7 is compacted, and in the cavity of the cavities of the molds 2 is pushed upwards. At the end of the pressing operation, the drive lifts the yoke 1 with the holders and the molding sand enclosed in their cavity. By making the holes in the counter stamp with expansion, the possibility of jamming the void forming agents is excluded, since the molding mixture, which is entrained by the void makers in the gap between the walls of the holes in the counter stamp and 2Q, with the outer surface of the void makers, enters the cage and is then removed using special trays (not shown). Next, the molded product is removed from the mold 7 and removed from the table 6. The location of the inclined surface of the working hollow former at an angle of 23-34 ° to its longitudinal axis reduces the resistance of the molding mixture to the emptying former when immersed in the mold. reduce the force acting. on the drive.

Данные по определению оптимальных параметров приведены в таблице.Data on the determination of optimal parameters are given in the table.
