Description
Technical Field
[0001] This utility model relates to the field of tire mold manufacturing technology, and in particular to an installation structure for movable type blocks. Background Technology
[0002] In tire molds, movable type blocks are key components used to change the text on the tire sidewalls. They are mostly fan-shaped and mounted on the side plates of the mold. As the tire industry develops, the sidewall markings, numbers, patterns, and certification marks are constantly changing and increasing, requiring frequent updates to the movable type blocks on the molds.
[0003] However, existing movable type installation methods mostly use bolt fixing, which requires disassembly and replacement from the back of the side plate. This process is not only time-consuming and labor-intensive, but also the mold is easily damaged during hoisting and flipping of the side plate, and there are certain personal safety hazards. Existing solutions generally have the problems of complex structure and high processing difficulty, making it difficult to achieve mass production. In order to solve the above problems, this utility model provides a movable type installation structure. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an installation structure for movable type blocks.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An installation structure for movable type includes a side plate, movable type, a spring, and a limiting device. The side plate has an installation groove, and the bottom of the installation groove has a flat-bottomed hole. The side plate also has an installation groove, and the bottom of the installation groove has a threaded hole. The movable type has an installation groove, and the movable type is movably placed in the installation groove. The spring is placed in the flat-bottomed hole and is used to apply an upward elastic force to the movable type.
[0007] The limiting device includes a limiting shell, a rotor, a second spring, and a rotor limiting plate. The top surface of the limiting shell is provided with a countersunk hole, and the vertical surface of the limiting shell facing the mounting groove is provided with a mounting groove. The rotor is a columnar structure, and its vertical surface includes a cylindrical surface and a rectangular plane. The top surface is provided with a threaded hole coaxial with the cylindrical surface.
[0008] As a further improvement of this utility model, the limiting device also includes a headless bolt, a cap and a bolt, and the inner surface of the mounting groove four is provided with a flat bottom hole two and the inner bottom surface is provided with a countersunk hole two.
[0009] As a further improvement of this utility model, the rotor is placed in the mounting groove four, and the axis of the threaded hole two is collinear with the axis of the countersunk hole one, and the spring two is placed in the flat bottom hole two.
[0010] As a further improvement of this utility model, the rotor limiting plate is placed in the mounting groove four and located between the rotor and the spring two, and is used to hinder the rotation of the rotor under the elastic force of the spring two.
[0011] As a further improvement of this utility model, the headless bolt is inserted through the countersunk hole and threadedly connected to the threaded hole.
[0012] As a further improvement of this utility model, the cap includes a top and a magnet. The top is made of the same material as the side plate, and the magnet has an adsorption force. The two are bonded together as one piece, and the cap is embedded in the countersunk hole.
[0013] As a further improvement of this utility model, the bolt passes through the countersunk hole two and is threadedly connected to the threaded hole one, for fixing the limiting device to the side plate.
[0014] As a further improvement of this utility model, two chamfers are provided between the cylindrical surface of the rotor and the rectangular plane, and chamfers are provided between the cylindrical surface of the rotor and its top and bottom surfaces.
[0015] The beneficial effects of this utility model are:
[0016] First, the structure is ingenious and the installation is convenient and reliable: the movable type blocks can be quickly locked and released by rotating the rotor in the limiting device. The operation is simple. The spring always provides an upward elastic force to ensure that the movable type blocks can be automatically pushed out when the unlocked state, making it easy to pick up and put down.
[0017] Secondly, the positioning is precise and the fixing is firm: the rotor adopts a special columnar structure, that is, the cylindrical surface is combined with the rectangular plane. When its cylindrical part is rotated out and inserted into the mounting groove of the movable type, the contact area is large, which can effectively limit the up and down movement of the movable type and ensure its stability in the working state.
[0018] Third, it provides clear operational feedback to prevent misoperation: The combined design of the spring and the rotor limiting plate makes the rotational resistance increase sharply when the rotor rotates to the locked position and the rectangular plane fits against the limiting plate. At the same time, it may produce changes in sound and feel. This provides the operator with clear tactile and auditory feedback to determine whether the movable type block has been tightened in place. It can also effectively prevent the rotor from rotating unexpectedly due to vibration or other reasons during the use of the mold, making it safe and reliable.
[0019] Fourth, it is easy to maintain and replace: the movable type blocks are independently detachable. When replacement or repair is needed, simply use a tool to rotate the headless bolt to unlock it. The spring force will automatically lift the movable type block, simplifying the maintenance process.
[0020] Fifth, standardized and modular design with high economic benefits: the limit device can be designed as an independent standard part, and mass production can be carried out in a series of specifications according to the size and use of different movable blocks. This modular design can significantly shorten the processing and production cycle of molds, reduce costs, and facilitate inventory management and replacement of spare parts.
[0021] Sixth, the appearance is neat and the integration is high: through the countersunk hole design and the cap that can be processed together with the limiting shell, the upper surface of the limiting device can be kept flush with the side plate surface after installation. The magnetic fixing method of the cap also makes it easy to install and remove while ensuring the flatness and aesthetics of the overall appearance. Attached Figure Description

Detailed Implementation
[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0034] Reference Figures 1-10 An installation structure for movable type blocks includes a side plate 1, movable type blocks 2, a spring 3, and a limiting device 4. The side plate 1 has an installation groove 11, and the bottom of the installation groove 11 has a flat-bottomed hole 12. The side plate 1 also has an installation groove 23, and the bottom of the installation groove 23 has a threaded hole 14. The movable type blocks 2 have an installation groove 3 21, and the movable type blocks 2 can be movably placed in the installation groove 11. The spring 3 is placed in the flat-bottomed hole 12 and is used to apply an upward elastic force to the movable type blocks 2.
[0035] The limiting device 4 includes a limiting shell 41, a rotor 42, a second spring 43, and a rotor limiting plate 44. The top surface of the limiting shell 41 is provided with a countersunk hole 411, and the vertical surface of the limiting shell 41 facing the mounting groove 11 is provided with a mounting groove 412. The rotor 42 is a columnar structure, and its vertical surface includes a cylindrical surface 421 and a rectangular plane 422. The top surface is provided with a threaded hole 423 coaxial with the cylindrical surface 421.
[0036] In this utility model, the limiting device 4 also includes a headless bolt 45, a cap 46, and a bolt 47. The headless bolt 45 is used to establish a threaded connection with the rotor 42 to achieve a specific operation. The cap 46 serves to fill and decorate the countersunk hole. The bolt 47 is used to firmly connect the limiting device 4 to the side plate 1. The inner surface of the mounting groove 412 is provided with a flat-bottomed hole 413, which is used to place the spring 43 to provide elasticity. The inner bottom surface is provided with a countersunk hole 414, which provides space for the installation of the bolt 47 and ensures the flatness after installation.
[0037] The rotor 42 is placed in the mounting slot 412, and the axis of the threaded hole 423 is collinear with the axis of the countersunk hole 411. This collinear design allows the headless bolt 45 to pass smoothly through the countersunk hole 411 and connect with the threaded hole 423. The spring 43 is placed in the flat hole 413. The spring 43 can effectively exert its elastic force in the flat hole 413 to hinder the rotation of the rotor 42 or assist its reset.
[0038] The rotor limiting plate 44 is placed in the mounting groove 412 and is located between the rotor 42 and the spring 43. It is used to resist the rotation of the rotor 42 under the elastic force of the spring 43. This resistance provides clear tactile feedback to the operator. The headless bolt 45 is inserted from the countersunk hole 411 and threaded to the threaded hole 423. This connection method realizes the power transmission from external operation to the internal rotation of the rotor 42.
[0039] The cap 46 includes a top 461 and a magnet 462. This combination design ensures both the uniformity of appearance and provides a magnetic fixing function. The top 461 is made of the same material as the side plate 1, and the magnet 462 has an adsorption force. The two are bonded together. The cap 46 is embedded in the countersunk hole 411, and the bolt 47 passes through the countersunk hole 414 and is threaded to the threaded hole 14 to fix the limiting device 4 to the side plate 1.
[0040] Two chamfers are provided between the cylindrical surface 421 and the rectangular plane 422 of the rotor 42. The chamfer design helps the rotor 42 to smoothly transition between different working positions when rotating. Chamfers are provided between the cylindrical surface 421 of the rotor 42 and its top and bottom surfaces. These chamfers facilitate the smooth rotation of the rotor 42 in the mounting slot and reduce frictional resistance.
[0041] The number of flat-bottomed holes 12 and springs 3 can be increased according to the size of the movable type block 2. The expandable design allows the structure to adapt to the needs of movable type blocks 2 of different sizes. When the headless bolt 45 rotates, it can drive the rotor 42 to rotate synchronously. Synchronous rotation realizes direct control from external operation to internal locking mechanism.
[0042] In use, the spring 3 is first placed in the flat-bottomed hole 12 at the bottom of the mounting groove 11 to limit its movement. Then, the movable type block 2 is placed in the mounting groove 11. At this time, downward pressure is applied to the movable type block 2, overcoming the elasticity of the spring 3 to move it downward. Simultaneously, the headless bolt 45 is rotated with a screwdriver, and the rotor 42 rotates with the headless bolt 45. When the cylindrical surface 421 of the rotor 42 exceeds the mounting groove 412, the rotor 42 engages with the mounting groove 21 on the movable type block 2, restricting its vertical movement. As the screwdriver is continued to be rotated, the cylindrical surface 421 extends beyond the mounting groove 412. When the volume of 412 reaches its maximum, the contact area between the rotor 42 and the mounting groove 21 reaches its maximum. At this time, the rectangular plane 422 of the rotor 42 fits against the rotor limiting plate 44. Under the action of the elastic force of the spring 43 and the rotor limiting plate 44, the resistance to the rotor 42 continuing to rotate increases sharply, restricting the free rotation of the rotor 42. At this time, the movable block 2 is fixed. Remove the screwdriver and put on the cap 46. The cap 46 is attracted to the bottom plane of the countersunk hole 411 on the top surface of the limiting shell 41 by the magnet 462 of the lower part. Adjust by rotation to make the upper surface of the cap 46 flush with the upper surface of the limiting shell 41. The installation is complete.
[0043] During disassembly, a large magnetic stone is used to remove the cap 46 from the countersunk hole 411 of the limiting shell 41. A screwdriver is inserted into the countersunk hole 411 and the headless bolt 45 is rotated in the same direction as during installation. The rotor 42 rotates accordingly. The rotation of the rotor 42 needs to overcome the elastic force of the second spring 43 and the rotor limiting plate 44, resulting in high rotational resistance. When the cylindrical surface 421 is in tangential contact with the rotor limiting plate 44, the rotational resistance decreases. As the rotor 42 rotates, the volume of the cylindrical surface 421 that extends beyond the mounting groove 412 will become smaller and smaller, and the contact area between the rotor 42 and the mounting groove 21 will also become smaller and smaller. When the rotor 42 is completely placed inside the mounting groove 412, the rotor 42 separates from the movable type 2. The rotor 42 no longer restricts the up and down movement of the movable type 2. At this time, the movable type 2 bounces upward under the elastic force of the first spring 3, and can be easily removed.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
