A tire mold with quick-release tread blocks

Abstract

This invention belongs to the field of tire mold technology, specifically a tire mold with quickly detachable tread blocks. Existing molds suffer from poor fixing of tread blocks, leading to them falling off during injection molding due to insufficient magnetic attraction, and causing misalignment that affects tire quality. The proposed solution includes a base with two symmetrically arranged support rods rotatably connected to its top. A top ring is rotatably connected to the top of each support rod, and a first motor is fixedly mounted on the top of the top ring. The output shaft of the first motor is fixedly connected to the corresponding support rod, and the two support rods are connected by a transmission connection. This invention is simple to operate and convenient to use, allowing for simultaneous fixing of multiple tread blocks before installation and facilitating rapid disassembly later. It also facilitates the fixing and installation of two molds and accelerates the drying and curing process of the rubber tire.

Description

Technical Field

[0001] This invention relates to the field of tire mold technology, and in particular to a tire mold with quickly detachable tread blocks. Background Technology

[0002] Tire tread patterns, also known as tire tread designs, primarily improve tire performance and enhance its appearance. They are generally molded or etched onto the convex portion of the tire tread, and their main function is to improve tire performance.

[0003] Application No. 201621221704.2 discloses a tire mold with quickly detachable tread blocks, including an upper mold body, a lower mold body, and a tread block body. The upper mold body is provided with a first positioning block, and the lower mold body is provided with a second positioning block. At least one set of positioning holes is provided along the circumferential direction inside both the upper and lower mold bodies, and a first strong magnet is placed inside each positioning hole. The tread block body is provided with a magnet mounting block, and a second strong magnet is placed on each magnet mounting block. The tire mold with quickly detachable tread blocks provided by this utility model allows the tread blocks to be connected to the mold body by the attraction of magnets. When the tire is demolded, the tread blocks separate from the mold body and are removed along with the tire. During mold assembly, the tread blocks are removed from the tire, cleaned, and then quickly attracted and assembled back to the mold body. The tread blocks are detachable and replaceable, and the mold pattern can be easily changed without altering the mold body, reducing tire and mold development costs.

[0004] Existing molds have poor fixing effect when fixing tread blocks. During injection molding, the magnetic attraction is not strong enough, which can cause the blocks to fall off. They can also become misaligned, affecting the quality of the tire. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of existing molds, such as poor fixing effect when fixing tread blocks, easy falling off during injection molding due to insufficient magnetic attraction, and skew, which affects the quality of tires. Therefore, this invention proposes a tire mold with quick tread block removal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] This invention is simple to operate and easy to use. It can facilitate the simultaneous fixing of multiple patterned blocks before installation and the quick disassembly of them later. It can also facilitate the fixing and installation of two molds and accelerate the drying and curing effect of rubber tires. Attached Figure Description

[0033] Working principle: During operation, the patterned block body 10 is placed in the corresponding placement slot 8, and the patterned block body 10 is attracted into the placement slot 8 by the magnet 9. The screw hole 11 and the screw 12 are aligned and correspond. Rotating the rotating ring 14, the rotating ring 14 drives multiple screws 12 to rotate simultaneously through the meshing of the ring rack 15 and multiple transmission gears 13. Under the action of the magnet 9, the rotating screws 12 are threadedly fixed to the patterned block body 10 through the threaded connection with the screw hole 11. At the same time, the placement slot 8 positions the patterned block body 10 when the screws 12 rotate. When it is necessary to install and fix the upper mold 3 and the lower mold 2, the screw 5 is aligned with the threaded groove 4 and placed. Rotating the internal gear ring 7, the internal gear ring 7 drives the screw 5 to rotate through the meshing of multiple driven gears 6.

The rotating positioning shaft 26 drives the fan blade 29 to rotate. The rotating fan blade 29 creates airflow, which can quickly dry the rubber tire in the mold. When the pattern block body 10 needs to be disassembled, rotate the rotating ring 14 in the opposite direction to move the screw 12 out of the screw hole 11, which facilitates disassembly. Then start the first motor 18 switch. The output shaft of the first motor 18 drives the two support rods 16 to move the positioning plate 19 upward through the meshing of the two sprockets and the chain. The moving positioning plate 19 drives the upper mold 3 to move through the baffle 21 and the pull rod 20, thereby allowing the rubber tire in the upper mold 3 and the lower mold 2 to be disassembled.
