(54) УНИВЕРСАЛЬНЫЙ БЛОК(54) UNIVERSAL UNIT

Изобретение относитс к области переработки полимерных материалов в универсальных блоках.The invention relates to the field of processing of polymeric materials in universal blocks.

Известны универсальные блоки дл изготовлени изделий из полимерных материалов , содержащие нeпoдвижнyFO плиту, сменный блок 1 .Universal blocks for the manufacture of products from polymeric materials are known, which contain an unmounted AF plate, a replaceable block 1.

Недостатком известныхблоков вл етс то, что они снабжены, как правило, индивидуальными выталкивател ми, закрепленными в специальной плите.A disadvantage of the known blocks is that they are, as a rule, equipped with individual ejectors fixed in a special plate.

Также известны универсальные блоки , содержащие неподвижную плиту, наружную клиновую обойму с направл ющими пазами, внутреннюю клиновую обойму, шарнирно св занную с плитой толкателей, и полуматрицы, размещенные во внутренней обойме 2.Also known are universal blocks comprising a fixed plate, an outer wedge yoke with guide grooves, an inner wedge yoke pivotally connected to the pusher plate, and a semi-matrix disposed in the inner yoke 2.

Известные универсальные блоки не обеспечивают надежного выталкивани издели в случае изготовлени изделий сплощными, без отверсти по оси издели , так как они могут прилипнуть к формующим поверхност м полуматрицы, что снижает надежность работы блока.The known universal blocks do not reliably push the product out if the products are made flat, without a hole along the axis of the product, since they can stick to the forming surfaces of the half-matrix, which reduces the reliability of the unit.

Цель изобретени - повышение надежности работы блока и расщирени ассортимента изготовл емых изделий.The purpose of the invention is to increase the reliability of the unit and the expansion of the range of manufactured products.

Согласно поставленной цели универсаль ный блок снабжен установленными в полуматрицах с возможностью перемещени в перпендикул рном разъему полуматриц направлении плитами с закрепленными в них хвостовиками и выталкивател ми издели , а во внутренней обойме выполнены сквозные отверсти под хвостовики, причем на неподвижной плите установлены упоры, взаимодействующие с хвостовиками.According to the set goal, the universal unit is equipped with plates installed in semi-matrixes that can be moved in the direction perpendicular to the semi-matrixes with plates attached to them and product ejector pushers, and through holes are made in the inner cage, and stops on the stationary plate are installed that interact with the channels. .

На фиг. 1 изображен универсальный блок в сомкнутом положении, продольный разрез; на фиг. 2 - то же, в разомкнутом положении, продольный разрез.FIG. 1 shows a universal unit in a closed position, a longitudinal section; in fig. 2 - the same, in the open position, a longitudinal section.

Claims

The universal block contains a fixed plate 1 with stops 2, an external wedge holder 3, an internal wedge holder 4 in which semi-matrixes 5 are installed. In semi-matrix 5 there are plates 6 with ejectors 7 of the product and shanks 8, plate 9 is removable. The inner wedge holder 4 is hinged connected through the pushers 10 to the plate 11: The outer wedge holder 3 is rigidly fixed to the base plate 12 connected to the bottom plate 13 by the guide columns 14. On the base plate 12 there is an associated sign holder 15 on which, in the case of manufacturing the product, Erste, set the mark. The unit works as follows. When the lower pressure is turned on, the press stem moves the movable part of the block along guide columns 14 to the upper position. In this case, the fixed plate 1 is in contact with the nozzle of the machine, material is injected, and after a certain exposure the movable part is moved to the lower position and the unit opens, the support plate 12 together with the clips 3 and 4 pushers 10 and the plate 11 of the pushers move down until the plate 11 touches with the bottom plate 13, after which the movement of the plate of the pushers with the pushers 10, and with them the sleeves 4, is stopped. The support plate 12, together with the yoke 3, continues to descend. At this moment, the yoke 3, moving relative to the yoke 4, pushes it away, since each of the two parts of the yoke 4 is located in the slots 3 located below the vertical one. The magnitude of the angle is set depending on the stroke of the press stock and the height of the block. In this way, the sleeve 4 moves apart in the horizontal direction until the support plate 12 is in its lowest position. Thus, the semi-matrices inserted into the seat of the holder 4 are opened along the parting line and the product 16 is released from the semi-matrix ejector 7 of the plate 6, the shanks 8 of which, when the connector of the holder 4 is pushed onto the stops 2 and move the plate 6 with the ejector 7. Using this universal The unit allows you to expand the range of manufactured products in the typical forms of inserts, which will reduce the cost of manufacturing equipment. Claims of the Invention A universal block comprising a fixed plate, an outer wedge holder with guide grooves, an inner wedge holder pivotally connected to the pusher plate, and a semi-matrix housed in the inner holder, characterized in that, in order to increase the reliability of the unit and expand the range. of manufactured products, it is equipped with semi-matrix installed with the possibility of moving in perpendicular to the connector of semi-matrix direction plates with fixed shanks and ejectors Cereal products, and in the inner cage is provided with through holes for the shanks, wherein on a fixed plate installed stops interacting with the shank.
