Abstract

VOLKANIZATSIONNYY PRESS FOR THE PRODUCTION OF RUBBER PRODUCTS WITH OPEN CAVITY, containing a fixed heating plate and a sub- traverse traverse associated with the mechanism of rotation of the mold core, characterized in that, in order to simplify the design of the press and improve the quality of products, such as a helmet-mask gas masks, the mechanism of the core rotation is implemented in the form of interacting with a movable crosshead rod, rigidly connected with the lever of the pusher, moved in the guides of the frame and hingedly connected by means of earrings and with a pivot on the axis of the lever ^ *, carrying a removable core-holder core and interaction with the limiter and spring-loaded stop.

A vulcanization press for the manufacture of rubber products with an open cavity, containing a fixed heating plate and a movable traverse, is known. with the core rotation mechanism of the mold. There are horizontally located Nyos presses designed for the manufacture of products such as the 5th and 1st Sapo rotation mechanism of the core is made in a vvde interacting with a movable cross member by means of a spring-loaded rod and a carriage moved to the stop with a core holder-core mounted on a rotary shaft with a toothed wheel. engages with a toothed rack-piston rod of a power cylinder mounted on a carriage. However, the use of two drives for moving the carriage and turning the core complicates the mechanism for turning the core of known presses and does not allow improving the quality of production of products of the type of helmet masks for gas masks. The proposed press differs from the known ones in that the mechanism of the core rotation is made in the form of mutually acting with a movable crosshead, rigidly connected with the lever of the jerm Movable in the guide frame to the hingedly connected by means of the earring with the rotary on otH lever carrying w-vemny core holder and vzamatseystvuyushchuyushch with the limiter and under the spring emphasis. This press, while simplifying the design of the core rotation mechanism, makes it possible at the same time to improve the quality of the manufacture of type 1 products using anti-gas shemashed masks by using a single drive for shifting the traverse and parts of the core rotation mechanism with the workpiece, which are strictly fixed when laying and removing from the mold Fig, 1 shows the described press in the initial position with a hole and half-form, front view; in fig. 2 - the same, with closed semi-form, side view; in fig. 3 the mechanism of the core rotation in the initial position and the section А-А °, in FIG. 4 - the same, with the core horizontally arranged with the half-openings open. Vertically vulcanizing with the use of the TaBBnetrFbiiu preos for the manufacture of rubber products with an open cavity, for example, helmet masks of gas masks, contains a stationary heating plate 1, mounted on the working table 2 of the press with the bottom half-form 3, and supported in the guides 4 from the power cylinder 5 to the yoke 6, connected with a heating plate 7 of the upper half of the mold 8 and connected with the meg mechanism of turning the core of the mold. The core rotation mechanism is made in the form of a 6-gi 9 interacting with a movable cross-bar, rigidly connected to the lever 10 of the pusher 11, moved in the slots t2 of the guide bracket 13 of the frame 14 and pivotally connected by means of the earring 15 to the rotary 16-axis lever 17 carrying remove the rod holder 18 of the core 19 and interact with the limiter 20 and the rotor and spring-loaded stop 21. Steam is supplied to the slab 1 via the steam line 22, and to the slab 7 - through the telescopic steam line 23. The hectare 9 moves in the guide 24 of the bi-directional beam apravl guides 25 and 26 fixed to the bracket 13 of the frame 14, the upper part 9 is thrust support collar 27. In order to change the angle of rotation of the core 19, yoke 6 is coupled with t goy 9 ,. adjustable in length by means of a threaded joint fixed by a lock nut 28. A workpiece, for example, an Anti-gas mask mask, is put on the core 19 and includes press drives. Under the action of the power cylinder 5, the yoke 6 goes down and releases the support flange 27 tons hy. At the same time, under the action of the spring-loaded stop 21 and its own weight, the lever 17 with the core 19 is rotated to the support surface A of the pusher 11, the core 19 in a horizontal position is lowered into the lower half of the mold 3, and the traverse, continuing downward, closes the half shapes 3 and 8 with the heart of 1 1 for carrying out the processes of forming and vulcanizing the preform. After the curing process of the traverse 6 is completed, lifting up with the help of the guide 24 and the support flange 27 raises the pull 9, which, in turn, by the lever 10 lifts the pusher 11 interacting via the link 15 and the supporting surface K with the rotary lever 17, Farther when it is vertical two-: the core 19 from the lower half of the mold 3 is rejected and on the axis 16 rotates the core to the required angle to remove the finished product. Then another blank is put on the core, and the cycle of the press is repeated.
