Description

(5) АВТОМАТИЧЕСКАЯ ФОРМОВОЧНАЯ МАШИНА(5) AUTOMATIC FORMING MACHINE

II

Изобретение относитс к литейному производству, в частности к формовочным машинам.,The invention relates to foundry, in particular to molding machines.,

Известна автоматическа формовочна машина, содержаща рабочий стол с устройством дл смены модельных плит, рольганг дл перемещени опок и модельных плит, шаговый толкатель с вилочным захватом дл подачи модельных плит на рабочий стол 1 J,A known automatic molding machine, comprising a work table with a device for changing model plates, a live roll table for moving the flasks and model plates, a stepper pusher with a forks for feeding the model plates to the work table 1 J,

Однако на известной машине нельз применить плавающие модельные плиты или изготовить необходимое количество форм на одной модельной плите , что сужает ее технологические возможности.However, it is not possible to use floating model plates on a known machine or to make the necessary number of forms on a single model plate, which limits its technological capabilities.

Цель изобретени - расширение технологических возможностей автомати- - ческой формовочной машины.The purpose of the invention is to expand the technological capabilities of the automatic molding machine.

Дл достижени указанной цели автоматическа формовочна машина, содержаща рабочий стол с устройством дл смены модельных плит, рольганги дл перемещени опор и модельныхTo achieve this goal, an automatic molding machine, containing a working table with a device for changing model plates, roll tables for moving supports and model plates.

ПЛИТ, шаговый толкатель с вилочным захватом дл подачи модельных плит на рабочий стол, снабжена приводными фиксаторами модельных плит, попар-г но установленными на боковых сторонах вилочного захвата.The PLATE, a step pusher with a forks for feeding model plates to the work table, is provided with drive clamps of model plates pairwise installed on the sides of the forks.

На фиг. 1 изображена предлагаема машина, хзбщий вид; на фиг. 2 разрез А-А на фиг. 1.FIG. 1 shows the proposed machine, the same type; in fig. 2, section A-A in FIG. one.

Claims

10 contains a frame 1, along the guides 2 of which the press-loading device 3 moves. On the frame 1 there is fixed a hopper with molding sand and a work table 5 with roller tables 6. Model plates 7 and 8 are moved by a step pusher 9, on. The lateral sides of the forks capture of which are located the driving clips 10, made in the form of piston actuators. Olgangs 11 and 12 serve to move model plates through them, and lifting tables 13 and I transfer model plates from one transport level to another. Through the roller table 15, flasks 16 and 17 are fed into the automatic molding machine, and through the roller table 18, they are removed from it. The automatic molding machine works as follows. In the initial position, the model plate 7 is mounted on the work table 5. The flask 16 is mounted on the model plate. The press-loading device 3 pours the mixture from the bunker into the flask and compacts the semi-plate. After the end of compaction, the flask rises to the transport level of the roller tables 15 and 18 by the stretching mechanism and the press-loading device 3 is pushed out onto the roller table 18, and the empty flask 17 is placed in the working position by the same movement. Then the cycle repeats. The movement (change) of the model plate occurs during the movement of the flasks. The lifting tables 13 and 14 are raised to the upper position, and when moving up, the table 13 removes the model plate 8 from the rollers of the roller table 11. Model plate 7 is lifted by the roller table 6 to the transport level of the rollers of the lifting tables 13 and 14, which are in the upper position. On the table rollers 13 there is another model plate 8, and on the table rollers 14 there is a free position. The driving clips 10 of the stepper pusher 9 are inserted into the corresponding grooves of the model plates 7 and 8. The stepper pusher 9 moves the model plates for such a distance that the model plate 7 is placed on the table T rollers and the model plate 8 on the roller table 6 of the desktop 5 By moving the roller table 6 down, the model plate is pressed against the work table 5. The drive locks 10 are led out of the slots of the model plates and the step pusher 9 returns to the initial position. Tables 13 and 14 are lowered down the model plate 7 remains on the roller table 12 and fed to the storage place, and the new model plate on the roller table 11 is fed to the position by the table skirtings 13. Thus, the automatic molding machine can work with the floating model plate, but If necessary, according to a given program, any model plate can remain on the desktop 5 to work out the required number of half-molds and after that it will be replaced with a new plate. When working with the shuttle movement of the model plates, the tables 13 and 14 are in the upper position, the drive clamps are constantly inserted into the corresponding grooves of the model plates 7 and 8 for forming the lower and upper half-forms. The step pusher 9 with model plates 7 and 8 performs a reciprocating motion, feeding on the live rolls 6 of the desktop 5 alternately model plates 7 and 8. In this case, the replacement of the model plates is similar to the replacement of the plates when working with the floating rig. The advanced technological capabilities of the automatic molding machine allow it to be used in multi-product production, where the automation of production processes has limited application. The invention includes an automatic molding machine comprising a work table with a device for changing model plates, roll tables for moving the flasks and model plates, a stepper pusher with a forks for feeding model plates to the work table, in order to expand its technological capabilities, it is equipped with driving clips of model plates, installed in pairs; on the sides of the forks. .
