Description

Technical Field

[0001] This utility model belongs to the technical field of tire mold cycle charts, specifically relating to an adjustable cycle chart for tire molds that does not require replacement. Background Technology

[0002] Tire cycle plates are a necessary and crucial indicator in tire production. They serve as a marker of the tire's production date and provide a basis for quality traceability. The cycle plates need to change with the tire's production date. They are generally made of aluminum sheets and are inserted into the cycle plate slot in the tire mold using a rubber hammer. They are fitted together with an interference fit. When replacing them, the cycle plate is removed by tapping it out with a pry bar. Since the cycle plates need to be replaced weekly, long-term operation inevitably causes damage / wear to the mold around the cycle plate slot. This will manifest as unevenness on the tire surface during later tire vulcanization, affecting the appearance. The removed cycle plates are already damaged and deformed and cannot be reused, increasing losses and costs. Utility Model Content

[0003] This utility model aims to provide an adjustable cycle plate for tire molds that does not require replacement. It is easy to operate, reduces wear and tear, and solves the problem that the current method of installing cycle plates by hammering them in with a rubber hammer and removing them by prying them out with a pry bar causes damage / wear to the mold around the cycle plate groove, which will manifest as unevenness on the tire surface during tire vulcanization.

[0004] Therefore, the technical solution adopted by this utility model is as follows: an adjustable cycle plate for tire molds that does not require replacement, including a dial wheel and a dial wheel box. Multiple dial wheels are arranged side by side and coaxially in the dial wheel box. The dial wheel box includes a box body and a box cover. The box body has a step along the circumference of the opening and a magnetic block is placed there. The box cover is attracted to the box body by the magnetic block. The box cover has square openings on the left and right sides that correspond one-to-one with the dial wheels and allow individual numbers of the dial wheels to be exposed. The dial wheels are engraved with numbers 0-9 in a circumferential direction at intervals, and there are grooves between adjacent numbers. The inner contour of the square opening has a protrusion that fits into the groove of the dial wheel contact surface, so that when the box cover is installed on the box body, it can lock the dial wheel to prevent it from rotating.

[0005] As a preferred embodiment of the above scheme, four dials are used, which is a reasonable design and convenient for adjustment to any number of cycles.

[0006] A further preferred embodiment is that the grooves between the dial numbers are triangular, and the inner side of the square opening has a protrusion that matches the adjacent triangular grooves of the same number. The structure is reasonably designed and conveniently locks the dial to prevent it from rotating.

[0007] A further preferred embodiment is that the lid is made of steel, which is low in cost and easy to attach to the magnetic block.

[0008] A further preferred embodiment is that the square end of the box body is provided with a magnetic block placement groove along the step towards the side wall. One end of the magnetic block is fixed in the magnetic block placement groove, and the other end is placed on the step with its side flush with the side of the step. The structure is reasonably designed.

[0009] A further preferred embodiment is that the end of the dial away from the cover has a gap with the housing, effectively preventing interference between the dial and the housing from affecting the dial's rotation.

[0010] A further preferred embodiment is that the dial uses a digital groove structure with a groove depth of 0.6mm to 0.8mm to ensure the engraving effect and the depth is reasonable so that rubber vulcanizing liquid is not easily retained.

[0011] The beneficial effects of this utility model are:

[0012] (1) Compared with the current method of using a rubber hammer to knock in the periodic plate when it is placed and a pry bar to knock it out when it is replaced, this solution uses multiple dials arranged in parallel and coaxially in the dial box. The production cycle can be adjusted by turning the dials, and there is no need to replace the periodic plate for each batch. At the same time, the dials are engraved with numbers 0-9 in sequence in the ring direction. The first two digits are the year and the last two digits are the week number. The design is reasonable. It can be adjusted to any cycle number without placing or taking out the periodic plate. The concept is novel and the design is ingenious.

[0013] (2) The box body is provided with steps and magnetic blocks along the circumference of the opening. The box cover is attracted to the box body by the magnetic blocks. The box cover is easy to install. Just adjust the dial to the appropriate position and then stick the box cover on. When the box cover needs to be removed, just use a larger magnet to hold the box cover and pull it out. The operation is simple and convenient, effectively saving the cost of making and replacing the cycle plate. It effectively prevents damage / wear to the mold around the cycle plate groove caused by replacing the cycle plate. This will be reflected in the unevenness of the tire surface during the later tire vulcanization.

[0014] In summary, this utility model has the advantages of eliminating the need for replacement, saving the cost of replacing the cycle plate, and simplifying the operation of changing the cycle plate value. Attached Figure Description

[0016] Figure 2 This is a side sectional view of the display box cover of this utility model.

[0017] Figure 3 This is a schematic diagram of the box lid.

[0018] Figure 4 This is a schematic diagram of the structure of this utility model installed inside a tire mold. Detailed Implementation

[0019] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0020] Combination Figure 1 — Figure 4 As shown, a tire mold adjustable cycle plate that does not require replacement consists of a dial wheel 1 and a dial wheel box 2.

[0021] Multiple dials 1 are arranged side by side and coaxially inside the dial box 2.

[0022] Four dials are preferably used.

[0023] The dial box 2 consists of a box body 21 and a box cover 22. The box body 21 has a step along the circumference of the opening and a magnetic block 211 is placed there. The box cover 22 is attracted to the box body 21 by the magnetic block 211. The box cover 22 has square openings 221 on the left and right sides, which correspond one-to-one with the dial 1 and allow individual numbers of the dial 1 to be exposed. The dial 1 is engraved with numbers 0-9 in a circumferential manner, and there is a groove 11 between adjacent numbers. The inner contour of the square opening 221 has a protrusion that fits into the groove 11 of the dial 1, so that when the box cover 22 is installed on the box body 21, it can lock the dial 1 to prevent it from rotating.

[0024] The dial 1 uses a digital slot structure, and the depth of the digital slot is preferably 0.6mm to 0.8mm.

[0025] The groove 11 between the numbers on the dial 1 is triangular, and the inner side of the square opening 221 is provided with a protrusion that matches the adjacent triangular grooves of the same number.

[0026] The lid 22 is preferably made of steel.

[0027] The square end of the box 21 is provided with a magnetic block placement groove 212 along the step towards the side wall. One end of the magnetic block 211 is fixed in the magnetic block placement groove 212, and the other end is placed on the step with its side flush with the side of the step.

[0028] The end of the dial 1 furthest from the cover 22 has a gap with the housing 21, which effectively avoids interference between the dial 1 and the housing 21, thus preventing the dial 1 from rotating.

[0029] The tire cycle mark is a necessary and crucial indicator in tire production, serving as a marker of the tire's production date and providing a basis for quality traceability. The cycle mark contains a 4-digit number; for example, 1822 indicates the production date as the 18th week of 2022, and it is located on the inner ring of the tire's outer sidewall.

[0030] When it is necessary to adjust the number of production cycles, simply use a large magnet to pull away the cover 22, thereby opening the dial box 2 to expose the dial 1. Then, manually rotate the dial 1 to the corresponding number, and then put the cover 22 back on. The cover 22 is then re-attached and fixed by the magnetic block 211.
