Description

Technical field

The invention relates to a mounting machine for opening and closing a segmented vulcanizing tire mold.

State of the art

Tire tire pressing is carried out in molds placed in vulcanizing presses. For this, paired or segmented molds are used. Molds are opened by leaving the upper press plate. Currently, two mold designs are used: paired molds and segmented molds.

Paired molds can be used for modern designs of projectors with difficulty, since the design and appearance of modern protectors requires a radial opening of the mold, which the design of a paired mold allows with difficulty. The use of paired molds makes it difficult to comply with the standard treads.

The design of segment molds is complex and consists of several sets. For segmented molds, it is necessary to ensure radial movement of the segments so that the pressed tires can be removed. Currently, sophisticated equipment is used, which the segments move depending on the movement of the top plate. The chosen solution method leads to difficulties, especially for molds for trucks and huge tires. This design leads to the fact that most of the mass of the mold remains on the upper moving plate of the press. Moving this mass leads to more wear of the leading parts. When opening, the mass of the mold moves off together with the upper press plate, and this significantly slows the opening of the press, as it causes vibrations of the upper press plate, which pose a risk of damage to the vulcanizing press (vulcanizer) or the mold.

The design of the segmented molds can be designed so that most of the mass of the mold remains below. We are talking about the so-called molds with lower opening. For their application, however, it is necessary to make changes to the vulcanization press or use other equipment to open them (SU 1308186 A3, 04/30/1987 KONTINENTAL GUMMI-VERKE AG (FIRM), FRID KRUPP GMBH (FIRM)).

Utility Model Description

The disadvantages of the existing methods of opening the molds are eliminated to a significant extent by the installation machine according to the technical solution, consisting of a frame structure. The essence of the technical solution lies in the fact that the bottom plate is attached to the frame, the centering circle in which the hydraulic cylinder is installed. Next, the main plate is installed on the frame, on which centering cubes and supporting elements are installed. Grooves are made on the main plate, in which the grips of the mold segments move. Captures of segments are controlled by a control mechanism located on the bottom plate. From the point of view of closing the mold, it is advantageous to create a clamping element under the shoulder on the hydraulic cylinder, with which the upper part of the mold is pressed against the lower part of the mold. The advantage of the technical solution is that it allows the use of segmented vulcanizing molds for the production of tires with modern block patterns in autoclaves, which today's technology does not allow. The advantage of the design is its versatility, covering the entire scale of tire sizes with minimal structural changes.

in Fig.2a - section AA is shown in Fig.2.

Implementation example

The mounting machine according to Fig. 1 ÷ 2a has a frame 1 with a frame structure. The bottom plate 2 and the centering circle are attached to the frame 1. On the frame 1 there is further placed the main plate 3, which consists of 8 segments, which, after mechanical connection, form a circular segment adjacent by a smaller diameter 31 to the centering circle 10. The frame 1 is attached vertically movable hydraulic cylinder 4. On the main plate 3, centering cubes 5 are installed, the minimum number of which is 3 pcs. Next, on the main plate 3, support elements 6 are placed, the number of which corresponds to the number of segments of the mold 12. On the main plate 3, grooves 7 are made in which the grippers of the segments 8 of the mold 12 move. The grips of the segments 8 are controlled by a control mechanism 9, which is laid on bottom plate 2. Three safety hooks 11 are attached to the main plate 3, preventing the lifting of the mold 12 during its maintenance. The mold 12 consists of a lower part 13, an upper part 14 of the segments 17 and a central part 16 in which the tire tire blank is laid.

In the manufacture of tires, proceed as follows:

- the lower part 13 of the mold 12 is mounted on the centering circle 10 and on the centering cubes 5, and the pin 15 will fit into the grips of the segments 8, which is an integral part of the segments 17 of the mold 12. The grips of the segments 8 are now in the first extreme position 71 of the groove 7;

- in the so-installed lower part 13 of the mold and segments 17 of the mold 12 put the tire tire blank with the central part 16;

- after inserting the tire tire blank into the lower part 13 of the mold 12, the grippers of the segments 8, using the control mechanism 9, will move to the second extreme position 72 of the groove 7, i.e. in the direction of the hydraulic cylinder 4. The segments 17 of the mold 12 are pulled together;

- on so tightened segments 17 of the mold 12 set the upper part 14 of the mold 12;

- this upper part 14 of the mold 12 is pressed against the lower part 13 by means of a hydraulic cylinder 4 and by means of a tightening element 18 mounted under a shoulder 19 created on the hydraulic cylinder 4.

Mold 12 is now prepared for shipment to a separate tire pressing equipment.

After the end of the pressing cycle in a separate pressing equipment, the mold 12 is brought back to the mounting machine. The mold 12 is mounted on the centering circle 10 and on the centering cubes 5. A pin 15 will sit in the groove 81 of the gripping segments 8. Element 18 will remove the upper parts 14 of the mold 12 in an upward direction. 12. Gripping the segments 8 using the control mechanism 9 from the second extreme positions 72 in the groove 7 are pushed towards the outer perimeter of the main plate 3 to the first extreme position 71, which will lead to the removal and stretching of the segments 17 of the mold 12. Now you can remove the finished tires from the lower part 13 of the mold 12.

Industrial applicability

The mounting machine for opening and closing a segmented vulcanizing mold for tire production, according to the technical solution, is applicable for preparing tire production, especially suitable for EM tires.
