Description

Technical Field

[0001] The utility model relates to the technical field of weekly number plates, in particular to a weekly number plate for tire vulcanization. Background Technique

[0002] At present, regulations require that the production cycle of tires must be printed on the tires for query. Therefore, when making tire molds, mounting grooves for installing and replacing the production cycle number plates of tires are designed on the mold side plates. When the tires are vulcanized, the production cycle number plates can be installed in the grooves. The cycle number plates need to be closely fitted with the mold mounting grooves and are replaced once a week. In this way, the numbers on the cycle plates can be printed on the tires, which is convenient for tire tracking and production cycle query.

[0003] At present, major tire enterprises mostly use aluminum materials for the weekly number plates. When installing, a hammer is mostly used for indirect knocking to make the aluminum cycle plates fit tightly or with interference with the mold mounting grooves. Interference aluminum chips are generated around the mounting grooves due to knocking. Since aluminum is relatively soft, manual grinding is required to remove the interference aluminum chips. For the cycle plates after grinding, the surfaces of the produced tires are often accompanied by roughness, scratches, color differences, etc. In view of this, this article proposes a weekly number plate for tire vulcanization that does not require surface grinding. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that major tire enterprises mostly use aluminum materials for the weekly number plates. When installing, a hammer is mostly used for indirect knocking to make the aluminum cycle plates fit tightly or with interference with the mold mounting grooves. Interference aluminum chips are generated around the mounting grooves due to knocking. Since aluminum is relatively soft, manual grinding is required to remove the interference aluminum chips. For the cycle plates after grinding, the surfaces of the produced tires are often accompanied by roughness, scratches, color differences, etc., and a weekly number plate for tire vulcanization is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A weekly number plate for tire vulcanization, including a mold side plate and a plate body, the plate body is installed on the mold side plate and is made of high-temperature resistant plastic material;

[0007] At least one reinforcing rib is fitted and installed around the plate body.

[0008] Preferably, a movable type block is detachably connected between the plate body and the mold side plate, and a mounting groove for fitting and connecting with the plate body is arranged at the upper end of the movable type block.

[0009] Preferably, a groove is communicated with one side of the mounting groove, and a convex block for fitting and connecting with the inner cavity of the groove is vertically connected to one side of the lower surface of the plate body.

[0010] Preferably, a disassembly groove is connected below the installation groove, and a through hole is provided below the disassembly groove.

[0011] Preferably, the movable type block is bolted to the mold side plate through perforations.

[0012] Preferably, the bottom edge of the card body is provided with a chamfer.

[0013] Compared with the prior art, the utility model provides a weekly number plate for tire vulcanization, which has the following beneficial effects:

[0014] 1. The tire vulcanization week number plate is made of high-temperature resistant plastic material. During the installation of the plate, the excess plastic on the edge of the installation groove can be directly cut off to form plastic filaments, which can then be gently wiped off with a rag. The surface does not need to be polished, avoiding roughness, scratches, color difference, etc. on the surface of the tire week number plate, thereby improving the appearance of the tire.

[0015] 2. The weekly number plate used for tire vulcanization indirectly connects the mold side plate and the plate body through the movable type block. If the mounting groove on the movable type block is damaged, the bolt can be removed and replaced with a spare movable type block, which is convenient and fast, saving mold maintenance costs and improving production efficiency.

[0016] 3. The weekly number plate used for tire vulcanization can increase the deformability around the plate body through reinforcing ribs. After the reinforcing ribs around the plate body are squeezed, they can be deformed according to the shape of the inner wall of the installation groove, which is convenient for the weekly number plate body to fit closely with the installation groove, so that the weekly number plate body is not easy to fall off during installation, and at the same time, it can also reduce the interference plastic cutting at the edge of the installation groove, thereby improving the installation convenience.

[0017] 4. The weekly number plate used for tire vulcanization can be used to indicate the installation direction of the weekly number plate body by means of the grooves and protrusions that are embedded in the installation groove in the movable type block and the lower surface of the plate body. That is, only when the protrusion under the plate body and the groove in the installation groove correspond to each other, the plate body can be embedded and installed in the installation groove, which can effectively avoid the weekly number plate from being installed upside down or inverted, and ensure the accuracy of installation.

[0018] 5. The week number plate used for tire vulcanization has a chamfered bottom edge of the plate body so that the bottom surface size of the plate body is smaller than the size of the upper opening of the installation groove, which can help the plate body to be more easily placed in the opening of the installation groove, and the chamfered bottom of the plate body can be used to help the plate body to be accurately fitted into the installation groove, which is not easy to cause installation deviation, thereby improving the installation efficiency of the plate body.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0025] Referring to the attached Figures 1-3 , a weekly number plate for tire vulcanization includes a mold side plate and a plate body 2. The plate body 2 is made of high-temperature resistant plastic material, specifically ultra-high temperature resistant PC plastic, with high hardness and a high-temperature resistance of ≥150 °C. It fits tightly with the following installation groove 3. The installation groove 3 is made of steel. During installation, the excess plastic at the edge of the installation groove 3 is cut off to form plastic filaments, which can then be gently wiped off with a cloth. There is no need to polish the surface to avoid roughness, scratches, color differences, etc. on the surface of the tire weekly number plate, and to improve the appearance quality of the tire.

[0026] It should be noted that since the plate body 2 of the tire weekly number plate needs to be replaced weekly, frequent replacement is likely to cause damage to the periphery of the following installation groove 1. This installation groove 1 is equivalent to the connection groove for directly installing the weekly number plate on the mold side plate in the prior art. After the damaged installation groove 1, it is easy for the appearance of the vulcanized tire to produce rubber edges and damaged convex and concave points, resulting in defective products. After the damage, the mold needs to be repaired, which not only affects the production plan but also increases the mold repair cost. Therefore, in this article, the mold side plate and the plate body 2 are indirectly connected through the movable type block 1. The movable type block 1 is detachably fixed to the mold side plate by bolts. If the movable type block 1 is damaged, the bolts can be removed and a spare movable type block 1 can be replaced, which is convenient and fast, saves the mold repair cost, and improves the production efficiency.

[0027] In this embodiment, an installation groove 3 for fitting and connecting with the card body 2 is arranged at the upper end of the movable type block 1. The inner dimension length of the installation groove 3 satisfies 4mm ≤ length ≤ 20mm, and the depth ≥ 2mm. A disassembly groove 4 is also communicated below the installation groove 3. The disassembly groove 4 is mainly used to place the hexagonal column block at the head of the screw. A perforation 5 is communicated below the disassembly groove 4. The movable type block 1 is bolt-connected to the mold side plate through the perforation 5, that is, the bolt passes through the perforation 5 and is threadedly fixed to the mold side plate.

[0028] It should be noted that the matching precision requirement between the periodic card body 2 and the installation groove 1 is relatively high, and the processing requirements are very strict. If the size of the installation groove is too small, it is easy to fall off. If the size of the installation groove 1 is too large, the periodic card body 2 will fall off during the vulcanization process, affecting the appearance of the tire. Therefore, at least one reinforcing rib 8 is attached to the periphery of the card body 2. The number of reinforcing ribs ≥ 1. The reinforcing rib 8 is directly injection-molded. The protruding size of the reinforcing rib ≥ 0.1mm. The shape of the reinforcing rib 8 can be diverse, such as arc-shaped, long-strip-shaped, irregular, etc., which is convenient for the weekly card body 2 to be closely matched with the installation groove 1, and the weekly card body 2 is not easy to fall off during installation. At the same time, it can also reduce the over-molded plastic cut at the edge of the installation groove 1 and improve the installation convenience.

[0029] It should be added that since most of the existing periodic cards are stamping aluminum cards and do not have direction indication, it is easy for novices to install the weekly cards in the wrong order, resulting in defective products. Therefore, a groove 6 is communicated on one side of the installation groove 3 in the movable type block 1, and a convex block 9 that is vertically connected to and fits into the inner cavity of the groove 6 is arranged on one side of the lower surface of the card body 2. The height dimension range of the groove 6 and the convex block 9 is 0.1 - 10mm. The groove 6 and the convex block 9 can be various shapes such as a cylinder, a cube, a cone or a combination of a cylinder, a cube and a cone that match each other. The design purpose is to make the weekly card have direction indication, avoid the weekly card being installed in the wrong order or upside down, and ensure the installation accuracy;

[0030] It is further added that the groove 6 and the convex block 9 are mainly used to indicate the installation direction of the movable type block 1 and the card body 2. Therefore, the groove 6 can also be arranged on one side of the lower surface of the card body 2, and the convex block 9 can also be fixedly installed on one side of the installation groove 3 in the movable type block 1.

[0031] It is further explained that since the size of the weekly card is small and the temperature during vulcanization is relatively high, about 170°C, it is very difficult to accurately position when replacing the periodic card, resulting in installation deviation, which is likely to cause the tire surface to be uneven or produce flash, resulting in poor tire appearance. Therefore, a chamfer 7 is arranged at the bottom edge of the card body 2. The size of the chamfer 7 is 0.1 - 1mm. After chamfering, the periodic card body 2 and the installation groove 1 can be accurately positioned, and it is not easy to cause installation deviation, improving the installation efficiency.

[0032] The present utility model

[0033] 1) The plate body 2 is made of high temperature resistant plastic material, so that during the installation process of the plate body 2, the excess plastic on the edge of the installation groove 3 can be directly cut off to form plastic filaments, which can then be gently wiped off with a rag without polishing the surface, thus avoiding roughness, scratches, color difference, etc. on the surface of the tire number plate and improving the appearance of the tire;

[0034] 2) Use movable type block 1 to indirectly connect the mold side plate and the plate body 2. If the mounting groove 3 on the movable type block 1 is damaged, the bolt can be removed and the spare movable type block 1 can be replaced, which is convenient and fast, saving mold maintenance costs and improving production efficiency;

[0035] 3) The reinforcing ribs 8 can increase the deformability of the plate body 2. After being squeezed, the reinforcing ribs 8 around the plate body 2 can be deformed according to the shape of the inner wall of the installation groove 1, so that the plate body 2 and the installation groove 1 can be closely matched, so that the plate body 2 is not easy to fall off during installation. At the same time, it can also reduce the interference plastic cutting at the edge of the installation groove 1, thereby improving the installation convenience;

[0036] 4) The grooves 6 and protrusions 9 that are embedded in the mounting groove 3 in the movable type block 1 and the lower surface of the card body 2 can be used to indicate the installation direction of the weekly number card body 2. That is, only when the protrusion 9 under the card body 2 and the groove 6 in the mounting groove 3 correspond to each other, the card body 2 can be embedded and installed in the mounting groove 3, which can effectively avoid the weekly number card from being installed upside down or upside down, ensuring the accuracy of the installation.

[0037] 5) By setting the chamfer 7 at the bottom edge of the card body 2, the size of the lower bottom surface of the card body 2 is made smaller than the size of the upper opening of the installation groove 3, which can help the card body 2 to be more easily placed in the opening of the installation groove 3, and the chamfer 7 at the bottom of the card body 2 can help the card body 2 to be accurately fitted into the installation groove 3, which is not easy to cause installation deviation and improves installation efficiency.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
