Description
Technical Field
The utility model relates to a removable tire mould structure of steel sheet and decorative rib.
Background
The traditional steel sheet inlaying method usually adopts an extrusion fixing or reverse casting mode to inlay and fix the steel sheet on the pattern block main body, or adopts the processes of electric spark machining, direct carving and the like to directly form the steel sheet on the pattern block substrate. As for the ribs, it is usually done by one of direct engraving, electric discharge, casting, decal, and the like. No matter which process is adopted, the rib can not meet the requirement of being capable of changing at any time, and the tire with one specification of the pattern is fixed.
When a tyre manufacturer wants to produce tyres with the same specification and different pattern styles, the steel sheets and the pattern ribs are fixed and unchangeable, so the mould needs to be processed again. Moreover, the pattern of the tire on the market changes rapidly, and the requirements for the pattern of the tire are different and change all the time on different road surfaces, different use environments, different use conditions, different seasons and the like. For tire manufacturers, the development cost of the mold and the development period of the tire product bring about a lot of pressure to the tire manufacturers, so that the manufacturers want to shorten the development period of the product and save the manufacturing cost of the mold in a thousand-square way.
Disclosure of Invention
The utility model aims at the above-mentioned problem, provide a shorten product development cycle and practice thrift mould manufacturing cost's removable tire mould structure of steel sheet and decorative rib.
The utility model aims to realize the structure of the tire mold with the replaceable steel sheet and the replaceable pattern rib, which comprises a pattern block, and the steel sheet and the pattern rib which are embedded on the pattern block; at least one side of the steel sheet or/and the pattern rib is provided with a through hole which penetrates through the pattern block and is provided with a counter bore, a pin with a pin cap is inserted into the through hole, the pin cap is in interference fit with the counter bore, and the top surface of the pin cap is flush with the inner surface of the pattern block; when the pin is positioned at the exhaust position of the pattern block, an exhaust hole for exhausting when the tire is vulcanized is formed along the pin shaft of the pin, so that the pin forms an exhaust sleeve structure; the steel sheet or/and the pattern rib are provided with convex shoulders at the positions corresponding to the lower parts of the pin caps, and the convex shoulders are buckled and pressed by the pin caps to form a fastening structure of the steel sheet or/and the pattern rib embedded on the pattern block; the pin is withdrawn from the through hole by applying force to the bottom of the pin from the bottom end of the through hole, so that the steel sheet and/or the ribs can be detached and replaced.
In the utility model, at least one through hole is arranged beside the steel sheet; at least two through holes are respectively arranged at each side of the pattern rib.
The utility model discloses, have following positive effect: the steel sheet and the pattern ribs are designed into structures which can be replaced according to needs, and the rapid switching of different steel sheet patterns and pattern patterns is realized. The fastening structure of the steel sheet and the pattern ribs ensures that the steel sheet and the pattern ribs have strong shape and size changeability, can change the pattern of the tire at any time, and realizes that different patterns share the mold pattern blocks, thereby achieving the purposes of saving the development cost of the mold and shortening the development period of the tire product.
The following examples are provided to further illustrate the present invention in conjunction with the accompanying drawings.

Detailed Description
Referring to fig. 1 to 5, the present embodiment is a tire mold structure with replaceable steel sheets and ribs, which includes a pattern block 1, and steel sheets 2 and ribs 3 embedded on the pattern block; one side of the steel sheet is provided with a through hole 4 which penetrates through the pattern block and is provided with a counter bore, two sides of the pattern rib are respectively provided with two through holes which penetrate through the pattern block and are provided with counter bores, a pin 5 with a pin cap is inserted into the through hole, the pin cap 6 is in interference fit with the counter bore 7, and the top surface 8 of the pin cap is flush with the inner surface 9 of the pattern block; when the pin is positioned at the exhaust position of the pattern block, an exhaust hole 10 for exhausting when the tire is vulcanized is formed along the pin shaft of the pin, so that the pin forms an exhaust sleeve structure; the steel sheet and the pattern ribs are provided with convex shoulders 11 at the positions corresponding to the pin caps, and the convex shoulders are buckled and pressed by the pin caps to form a fastening structure for embedding the steel sheet and the pattern ribs on the pattern blocks; the pin is withdrawn from the through hole by applying force to the bottom of the pin from the bottom end of the through hole, and the steel sheet and the pattern rib are detachable and replaceable.
The principle of the utility model is as follows: because the pattern blocks of the tire mold are originally required to be designed and processed with vent holes with the diameter of only 0.6-0.8mm at various dead corners, and the vent holes are used for exhausting air during tire vulcanization. Because the exhaust holes are very fine and difficult to directly drill, the exhaust holes are usually replaced by hollow exhaust sleeves with the inner diameter of 0.6-0.8mm and the outer diameter of about 3mm, so that bottom holes can be conveniently machined. After all, the diameter of 0.6-0.8mm has great processing difficulty, and the through hole with the diameter of 3mm is relatively easy to process. The utility model discloses these ingenious air discharge sleeves that utilize needs interference fit compress tightly steel sheet or decorative pattern muscle as the instrument, make steel sheet or decorative pattern muscle firmly fix on mould decorative pattern piece bottom, but do not influence the original exhaust function of air discharge sleeve again. When the pattern style needs to be changed, the steel sheet or the pattern rib can be compressed and a new pattern style can be formed only by withdrawing the compression exhaust sleeve of the steel sheet or the pattern rib to be changed, then pulling out the steel sheet and the pattern rib, replacing the new pattern and then installing a new exhaust sleeve in an interference fit manner. The utility model discloses, it has at least one to be used for by the little convex shoulder that the air discharge sleeve compressed tightly to design respectively in steel sheet and decorative pattern muscle one side or both sides, and the air discharge sleeve designs the structure of taking the round pin cap, and during the installation, this round pin cap structure corresponds the little convex shoulder that compresses tightly steel sheet or decorative pattern muscle, just can make steel sheet or decorative pattern muscle firmly inlay and set up on the mould decorative pattern piece. The utility model discloses, the boss for compressing tightly can correspond the tire decorative pattern and go up the exhaust hole position and set up. If the area to be pressed is free of or does not allow any venting holes, the venting sleeve in this position can be designed as a solid pin without an inner bore instead.
The utility model discloses, the little convex shoulder of steel sheet and decorative rib can adopt 3D to print the shaping, also can adopt the bonding, can also adopt stamping forming, can adopt welded forming even.
