Description

( ЗАЖИМНОЕ УСТРОЙСТВО дл ФОРМ(CLAMP FOR FORM

1one

Изобретение относитс к устройствам дл зажима частей форм, например, пресс-форм дл изготовлени полимерных изделий, в частности изделий из пенопластов.The invention relates to devices for clamping parts of molds, for example, molds for the manufacture of polymeric products, in particular products from foams.

Известно зажимное устройство дл форм, содержащее шарнирно закрепленный на одной из плит рычаг с захватным крюком с выступом и выемкой, взаимодействующими с cootвeтcтвyющими упорами плит формы П.Known clamping device for forms containing pivotally mounted on one of the plates of the lever with a gripping hook with a protrusion and recess, interacting with the corresponding lugs of plates of form P.

К недостаткам этого устройства относитс сложность его конструкции и невысока надежность в работе.The disadvantages of this device include the complexity of its design and low reliability in operation.

Наиболее близким к предлагаемому вл етс зажимное устройство дл форм, содержащее установленные в верхней и нижней плитах и закрепленные в последней направл ющие колонки, расположенные по разные стороны от взаимодействующего с верхней плитой эксцентрика и соединенные с ним посредством стержн 2.The closest to the present invention is a clamping device for forms, containing guide columns mounted in the upper and lower plates and fixed in the latter, located on opposite sides of the eccentric cooperating with the upper plate and connected to it by means of a rod 2.

К недостаткам этого устройства относитс создание невысоких усилий зажима плит формы, что снижает её технологические возможности, а также невысока надежность устройства.The disadvantages of this device include the creation of low efforts to clamp the plates of the form, which reduces its technological capabilities, as well as the low reliability of the device.

Цель изобретени - расширение технологических возможностей формы и повышение надежности устрюйства.The purpose of the invention is to expand the technological capabilities of the form and increase the reliability of the device.

Указанна цель достигаетс тем,что в зажимном устройстве дл форм, со- . держацем установленные в верхней и нижней плитах и закрепленные в пос- леднёй направл ющие колонки, расположенные по ргазные стороны от взаимодействующего с верхней плитой эксцентрика и соединенк«е с ним гюсредством стержн , в направл ющих колонках выполнены фигурные пазы с опорной поверхностью в их верхней части, в которых установлены концы стержн .This goal is achieved by the fact that, in the clamping device for forms, co. The holder mounted in the upper and lower plates and fixed in the last guide columns located on the opposite sides of the eccentric interacting with the upper plate and connected to it by means of a rod, figured grooves with a supporting surface in their upper part are made in the guide columns. in which the ends of the rod.

Claims

Fig. 1 shows the device in two states, top view; Fig. 2, a vertical section A-A in Fig. 1 (device in the open state on the left, in the right closed state); on fig.Z section bb in fig, 1. The device contains the bottom plate 1 ((|) ig.1) | in which the guide columns 2 are pressed, on which the top plate 3 is mounted. In the upper part of the guide columns 2, figured grooves 4 are made with a supporting surface 5 in their upper part An eccentric 6 located between the columns 2, which is connected to the top plate 3, with them by means of a rod 7 and having a handle 8. The device operates as follows. Install the top plate 3 on the guide columns 2, the rod 7 with the eccentric 6 located on it is inserted into the shaped grooves C, with its emphasis in the top plate 3. At the same time, the handle 8 of the eccentric knob is vertical. When the handle 8 is rotated to a horizontal position, the rod 7, moving along the figured groove C, abuts against the supporting surface 5 and the eccentric thus clamping the form plates. When the handle is turned up, the rod 7 freely emerges from the shaped grooves f of the guide columns 2, making the shape open. The use of the present invention allows to simplify the design of the device for clamping the forms, to ensure its quick-removal and to increase the reliability. Claiming device for molds, containing guide columns mounted on the top and bottom plates and mounted in the latter, located on opposite sides of the eccentric interacting with the top plate and connected to it by means of a rod, characterized in that and to increase the reliability of the device, figured grooves are made in the guide columns with a supporting surface in their upper part, in which the ends of the rod are installed.
