Abstract
The utility model discloses a mold for a solid tyre. The mold comprises an upper mold (1), a lower mold (2), a mold upper steel ring (3) and a mold lower steel ring (4), wherein the upper mold (1) and the lower mold (2) are respectively connected with the mold upper steel ring (3) and the mold lower steel ring (4) together by connecting bolts (5). The mold is characterized in that the connecting bolts (5) are distributed at 4-8 equal intervals on the circumference; the lower mold (2) is provided with a lower mold boss (10), and the lower mold (2) and the lower mold boss (10) are in an integrated structure; the lower mold boss (10) is provided with a central positioning block (11) which is matched together with the lower mold (2) and the mold lower steel ring (4) by a conical surface; and the central positioning block (11) slides up and down. The mold disclosed by the utility model has the advantages that by adoption of the central positioning block, the problem that the dynamic balance of a finished tyre product is not qualified is effectively solved, the qualification rate of the finished tyre product is greatly increased, and simultaneously the cost for processing and producing a rim and the solid tyre is reduced.
Description
Technical field:
The utility model relates to technical field of mold, especially relates to a kind of solid tyre mould.
Background technology:
The general wheel rim inner edge that uses coordinates the mode of location to produce solid tyre with mould steel ring at present, the solid tyre mould that this kind of mode used is made up of steel ring 3 and mould lower steel ring 4 on patrix 1, counterdie 2, mould, structure is comparatively simple, but there is following problem: 1, the dynamic balance performance of tire finished product is poor, while having relatively high expectations as dynamic balance performance, the qualification rate of tire finished product can be very low; 2, need because coordinating, higher to the processing request of wheel rim, wheel rim and the corresponding increase of tire production cost.
Utility model content:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of solid tyre mould is provided; Mainly solve the problem that existing solid tyre production qualification rate is low and cost is high.
The technical solution of the utility model is: a kind of solid tyre mould, and it comprises steel ring on upper die and lower die, mould, mould lower steel ring, on patrix and mould, steel ring, counterdie and mould lower steel ring link together by connecting bolt respectively; Its special character is, described connecting bolt circumference 4-8 part is equally spaced, and sets mould boss on described counterdie, and the two is integral type structure; On described counterdie boss, establish centralized positioning piece, centralized positioning piece and counterdie and mould lower steel ring are by together with cone match, and described centralized positioning piece slides up and down.
Compared with the prior art a kind of solid tyre described in the utility model has following good effect with mould: adopt centralized positioning piece, can ensure that wheel rim axis hole center and tire finished product center are on same axis, effectively solve the defective problem of tire finished product dynamic balancing, greatly improve tire product qualified rate, do not need to use wheel rim inner edge to coordinate location with mould steel ring simultaneously, reduce the processing request of wheel rim, and then reduced the processing cost of wheel rim, also reduced the production cost of tire simultaneously.

In figure: 1 patrix, 2 counterdies, steel ring on 3 moulds, 4 mould lower steel rings, 5 connecting bolts, 6 dies cavities, 7 wheel rims, 8 wheel rim axis holes, 9 rubber, 10 counterdie boss, 11 centralized positioning pieces.
Detailed description of the invention:
For Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model in detail; Illustrated embodiment is only for explaining the utility model, not for limiting scope of the present utility model.
Embodiment 1, referring to Fig. 4, Fig. 5, Fig. 6, need to be processed into steel ring 3 on patrix 1, counterdie 2, mould, mould lower steel ring 4 and centralized positioning piece 11 5 parts according to design; Steel ring 3, counterdie 2 on patrix 1 and mould are linked together by connecting bolt 5 respectively with mould lower steel ring 4, and these connecting bolt 5 circumference 4-8 parts are equally spaced; Counterdie 2 is integral type structure with counterdie boss 10; Centralized positioning piece 11 is installed on counterdie boss 10, and with counterdie 2 and lower steel ring 4 by together with cone match, centralized positioning piece 11 can slide up and down.
A kind of solid tyre mould described in the utility model, referring to Fig. 3,5, before tyre vulcanization, is loaded on wheel rim 7 and the assembly of rubber 9 in mould, and wherein rubber 9 drops in dies cavity 6, and wheel rim is assemblied on centralized positioning piece 11 by axis hole 8; When depanning, first use special ejecting mechanism that patrix 1 jack-up is left to counterdie 2, re-use special mechanism by centralized positioning piece 11 jack-up, the piece of centralized positioning simultaneously 11 drives tire finished product to move upward and leaves counterdie 2 and lower steel ring 4, and then tire finished product is taken off from center locating piece 11.
