Background

The tyre segment mould is used for final vulcanization moulding in the production of radial tyres. The main structure of the segmented mold comprises a shell and a cavity. The shell is also called a centripetal mechanism, is an external structure of the tire mold, and plays a role in connecting the vulcanizing machine with an internal cavity; the cavity is the internal structure of the mould and is the cavity formed with the tire blank. The shell component is provided with an outer die sleeve, a guide mechanism, an arch seat, an upper cover and a base; the mold cavity comprises pattern blocks, an upper side mold, a lower side mold, an upper steel ring, a lower steel ring and the like. The blocks in the mold cavity are important parts for directly forming the tire top pattern after the tire is vulcanized.

Chinese patent No. CN201720390199.2 in the prior art proposes a base mold for manufacturing a pattern block of a tire mold, and due to the adoption of the technical scheme, the two ends of the pattern forming surface extend out of a planar transition surface, which is equivalent to that the two ends of the base mold tilt upwards, so that the strength requirement is met while the overall thickness of the base mold is reduced, the cost is greatly saved, and the following problems still exist: because the end faces of the two adjacent arc sections have a certain gap when the base molds are assembled, the inner wall of the silica gel lining plate mold and the blending silica gel injected from the outer circular surface of the base mold are easy to permeate into the gap, so that the labor intensity is increased and the production cost of the silica gel is also increased when the subsequent procedures such as detection, milling, drilling, tapping, clamping and the like are carried out on the formed pattern modules.

The utility model has the advantages of simple and reasonable structure, the problem of seepage in the clearance of the base mould terminal surface of two adjacent circular arc sections is easily followed to silica gel among the effective solution prior art.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a schematic diagram of the overall structure of the present invention;

the reference numbers in the figures illustrate: 1. a base mold body; 2. forming a pattern forming surface; 3. a first seal groove; 4. a combined sealing mechanism; 401. a first retainer ring; 402. a second retainer ring; 403. a second seal strip; 5. a second seal groove; 6. a first seal strip.

Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a base mould for decorative pattern piece processing, includes base mould main part 1 and is provided with decorative pattern shaping face 2 in base mould main part 1 inboard, and the sculpture has the tire decorative pattern on the decorative pattern shaping face 2, and first seal groove 3 has been seted up to the position that both ends are close to decorative pattern shaping face 2 about base mould
