Description

one

Installations are known for the continuous manufacture of molded polymer products without the use of press equipment, for example, for vulcanizing hydraulic presses in the manufacture of rubber products, including an annular platform mounted on supports, on which is mounted a rectangular cross-section case with upper plates and side walls with limiting brackets, rail and profiled guides for stepping movement of spring-loaded cassette molds, each of which consists of interstitial, heating and insulating plates, the leaf springs, the upper and lower mold parts and cassette with grippers and rollers for moving the cartridge from the drive.

In known installations, a housing with rail and shaped guides is mounted on a platform along an annular contour for the step-by-step movement of the cassette molds associated with the chain transmission of the electric drive.

These units are designed for mass production of similar rubber products and are not suitable for the simultaneous manufacture of small batches of products of different assortment.

The proposed installation is characterized by the fact that the ring platform is made rotatable, with rollers for periodic movement by the power cylinder, on circular

rails mounted on supports under an annular platform on which sections of the section hull are radially mounted with limit arms, rail and profiled rails attached to the side walls. Outside the annular platform of the supports, a guide slide is installed for sequential movement, closing, squeezing and opening of the cassette molds by power cylinders mounted in the center of the installation on a stationary table.

This installation will ensure a reduction in the consumption of fixed assets for its production and will extend the range of simultaneous production

small batches of polymeric products of various assortment with different durations of vulcanization of workpieces.

Pa figs. 1 and 2 shows the installation in the section

and in the plan; in fig. 3 and 4 - longitudinal and transverse sections of the section body; in fig. 5 and 6 - cassette mold in transverse and partially longitudinal sections. Pa supports / mounted ring platform 2, on which is mounted a rectangular cross section housing with upper 11 liters, and side walls 4 with limiting brackets 5, rail and profiled guides and 7 for stepping movement of spring-loaded cassette molds, each which consists of intermediate, heating and insulating plates § 9 and 10, leaf springs //, upper and lower parts 12 and / 3 of the mold and a cassette with rollers 14 and clamps / 5 for moving the cassette away from the drive.

The annular platform 2 is rotatable with rollers 16 for periodic movement by a ram / 7 on circular rails 18 mounted on supports / under annular platform 2 / on which section bodies with radial brackets 5 fixed on the side walls, rail and profiled guides and 7. Outside the platform, on supports I, a slide 19 is installed to sequentially move, close, compress and unfold the cassette molds with power cylinders 20 and 21, which, when viewed mounted in the center of the installation on a stationary table 22, ensure the execution of the operations of forming and prepressing the blanks and recharging the molds.

Power cylinders P, 20 and 21 operate from a pumping station 23 mounted on the installation supports.

After placing the blanks in the mold, the cartridge with the mold is radially moved by the power cylinder 21 to the ring platform. At the same time, the parts of the mold and the cassette are closed and compressed to a predetermined pressing force. At the end of the radial movement of the mold, the electrical heating elements of the heating plates and the power cylinder 17 turn on, sequentially turning the ring platform with cassette molds one step. At this time, molding, vulcanization and, in the zone of action of the power cylinder 20, prepressing of the blanks takes place. Then with

with the help of the ram 21, the mold is moved along the guide slide 19 and is opened for recharging. Thus, the cycle of operation of the plant is continuously repeated.

Subject invention

An installation for the continuous manufacture of molded polymer products without the use of press equipment, for example, vulcanizing hydraulic presses in the manufacture of rubber products, comprising an annular platform mounted on supports, on which is mounted a rectangular cross-section case with upper plates and side walls made with limiting brackets ,

rail and profiled guides for the stepwise movement of spring-loaded cassette molds, each of which consists of an intermediate, heating and insulating plates, lamellar

springs, upper and lower parts of the mold and cassettes with rollers and grippers for moving the cartridge from the drive, characterized in that, in order to reduce the consumption of fixed assets for the manufacture of the installation and to expand the range of simultaneous production of small series of polymer products of different range, the ring the platform is rotatable, with rollers to periodically move the power

a cylinder, on circular rails mounted on supports under an annular platform on which sections of the sections are radially mounted, with limiting brackets, rail and

profiled guides, and outside the annular platform, a guide slide is mounted on the supports for sequential movement, closing, squeezing and unfolding of the cassette molds by power cylinders,

mounted in the center of the mouth: new on a fixed table.
