Description

Technical Field

[0001] This invention relates to the technical field of tire mold processing, and more specifically, to a lettering device for processing the side plate of an automobile tire mold. Background Technology

[0002] With the development of the automotive and tire industries, the development of automotive tire molds has been rapid. Among them, movable molds are widely used. A movable mold is a type of mold used for vulcanizing and molding various tires. It consists of a tread ring, a mold sleeve, and upper and lower side plates. Its structure is relatively complex and heavy. In order to mark the manufacturing information during the mold manufacturing process, it is also necessary to engrave words on the mold so that they can be directly branded onto the tire surface during casting.

[0003] Referring to Chinese patent application publication number CN116423461A, a tire mold tread block clamping device and method are disclosed, relating to the field of tire mold tooling fixtures. The device includes: a worktable on which a synchronous motion structure is mounted; the synchronous motion structure includes two synchronously moving drive mechanisms; and a self-centering clamping structure including two symmetrically arranged clamping mechanisms, each clamping mechanism being correspondingly mounted to one of the drive mechanisms. Each clamping mechanism has a clamping block rotatably connected to the main body of the clamping mechanism, and the clamping block has an engaging groove. The two engaging grooves simultaneously contact and clamp the tread block. This addresses the current limitations of... The problem of poor stability when clamping tread blocks with arc-shaped structures is addressed by using clamping blocks adapted to the ends of the tread blocks in conjunction with a self-positioning structure. These clamping blocks contact and move the tread blocks from both sides, and the rotation of the clamping blocks adapts to the position adjustment during the clamping process. Ultimately, the tread blocks are clamped simultaneously from both sides, achieving stable clamping. However, tire molds are usually assembled by splicing upper and lower side plates. In the case mentioned above, although the design of clamping blocks on both sides can clamp from both ends, there is a lack of clamping pressure between the upper and lower side plates, which can easily lead to seams and inaccurate positioning.

[0004] To address the aforementioned issues, we provide an engraving device for processing the side panels of automotive tire molds. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a lettering device for processing the side plate of an automobile tire mold.

[0012] Preferably, a pressure ball is also provided above the four limiting balls. The diameter of the pressure ball is larger than that of the limiting balls. The limiting balls are connected to the shaft sleeve by a compression spring. A compression bolt is also threaded in the shaft sleeve. A retaining sleeve is rotatably installed on the bottom end of the compression bolt. The pressure ball is fixedly installed in the retaining sleeve.

[0013] Preferably, the ear plate is further provided with a butterfly-shaped clamping block, which is closely attached to the arc surface of the ear plate. The ear plate is also provided with a screw hole on the side, and a fixing screw is installed on the butterfly-shaped clamping block, which cooperates with the screw hole.

[0014] Preferably, the moving mechanism includes guide rails installed on the top surface of the table and the sides of the table legs, and two support platforms are slidably installed on the guide rails.

[0031] Example 1

[0032] This invention discloses a lettering device for processing the side plate of an automobile tire mold. (See reference...) Figures 1 to 7 A lettering device for processing the side panel of an automobile tire mold includes a clamping part 1 and a lettering part 2. Both the clamping part 1 and the lettering part 2 are mounted on a table 3. The lettering part 2 includes two uprights 201. A crossbeam 202 is connected between the top ends of the two uprights 201. A slide block 203 is slidably mounted on the crossbeam 202. A carrier plate 204 extends from the side of the slide block 203. A carving machine 205 is mounted on the carrier plate 204. The carving machine 205 can be a CNC carving machine.

[0033] The clamping part 1 includes a clamping mechanism 11, which is mounted on the moving mechanism 12 for clamping and positioning the mold. The clamping mechanism includes a base 1101, with an ear plate 1102 mounted on the top of the base 1101. A bushing 1103 is rotatably mounted between the ear plates 1102. A clamping arm 1104 is also connected to the side of the bushing 1103. A vertical shaft 1105 is damped and rotatably mounted at the end of the clamping arm 1104. A clamp 1106 is mounted on both the upper and lower ends of the vertical shaft 1105, and a jaw 1108 is movably mounted inside the clamp 1106. A guide rod 1107 is also mounted between the upper and lower clamps 1106. The jaws 1108 are arc-shaped, and the tails of both jaws 1108 are slidably fitted onto the guide rod 1107. The clamp 1106 is also threaded with an adjusting bolt 1109, and the end of the adjusting bolt 1109 is rotatably connected to the jaw 1108. Specifically, in order to clamp the mold and keep the upper and lower side plates of the mold tightly clamped, clamps 1106 are installed at both ends of the vertical shaft 1105. The angle of the clamping arm 1104 can be adjusted by rotating the bushing 1103. The clamp 1106 is then placed on the mold. Then, the adjusting bolt 1109 on the clamp 1106 can be adjusted to push the jaw 1108 to move and press the jaw 1108 tightly against the mold. Through the squeezing and clamping of the upper and lower jaws 1108, the upper and lower side plates of the mold can be fixed together to maintain stability, so that the overall continuity can be maintained during subsequent engraving of letters and patterns.

[0034] Reference Figure 4 , Figure 7To limit the angle after adjusting the clamping arm 1104, a roller 1110 is fixedly fitted in the middle of the bushing 1103. A core sleeve 1111 is installed at the center of the upper ear plate 1102. The core sleeve 1111 is rotatably fitted inside the roller 1110, and the core sleeve 1111 has a cavity inside. Four limiting balls 1115 are arranged in the cavity. The core sleeve 1111 also has a sliding cavity for the limiting balls 1115 to move outward. Multiple limiting slots 1116 are opened on the inner wall of the roller 1110, which is opposite to the sliding cavity. A pressure ball 1114 is arranged above the four limiting balls 1115. The diameter of the pressure ball 1114 is larger than the diameter of the limiting balls 1115. 15 is connected to the shaft sleeve 1111 by a compression spring 1117. A compression bolt 1112 is also threaded inside the shaft sleeve 1111. A retaining sleeve 1113 is rotatably installed on the bottom end of the compression bolt 1112. A pressure ball 1114 is fixedly installed inside the retaining sleeve 1113. After adjusting the angle of the clamping arm 1104, the compression bolt 1112 can be tightened. The compression bolt 1112 can push the retaining sleeve 1113 and the pressure ball 1114 to slide downward. When the pressure ball 1114 slides down, it can squeeze and push the four limiting balls 1115 to slide into the corresponding sliding cavities until they cooperate with the limiting grooves 1116 on the inner wall of the roller 1110, thereby restricting the free rotation of the shaft sleeve 1103 and facilitating the fixing of the clamping arm 1104.

[0035] Reference Figure 1 , Figure 5 In addition, to facilitate adjustment of the position of the clamping mechanism 11 according to the length of the mold, the clamping part 1 also includes a moving mechanism 12. The moving mechanism 12 includes guide rails 1202 installed on the top surface and the side of the legs of the table 3. Two support platforms 1201 are slidably installed on the guide rails 1202. The support platforms 1201 are L-shaped and fit against the top surface and the side of the legs of the table 3. A motor frame is also installed at the bottom of the table 3. A servo motor 1203 is installed on the motor frame. The servo motor 1203 outputs... A drive disk 1204 is mounted on the shaft. The drive disk 1204 is elliptical in shape. Connecting rods 1205 are hinged to both ends of the drive disk 1204. The other end of the connecting rod 1205 is hinged to the support platform 1201. During operation, the servo motor 1203 can be started to drive the drive disk 1204 to rotate. When the drive disk 1204 rotates, the support platform 1201 can be pulled to slide on the guide rail 1202 by the connecting rods 1205 at both ends, which can ensure that the clamping mechanism 11 is accurately clamped on the mold.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 , Figure 3Based on Embodiment 1, a butterfly clamping block 1118 is also installed on the ear plate 1102. The butterfly clamping block 1118 is tightly attached to the arc surface of the ear plate 1102. A screw hole is also opened on the side of the ear plate 1102. A fixing screw 1119 is installed on the butterfly clamping block 1118. The fixing screw 1119 cooperates with the screw hole. Specifically, in order to facilitate the initial clamping and limiting of the mold, when the two bases 1101 are close to each other, the two butterfly clamping blocks 1118 can be pushed to fit against the two ends of the mold. Moreover, the ear plate 1102 is divided into upper and lower parts, and the butterfly clamping block 1118 is also divided into upper and lower parts, which can clamp the upper and lower side plates of the mold respectively, which is relatively firm.

[0038] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0039] The implementation principle of the engraving device for processing the side plate of an automobile tire mold according to an embodiment of the present invention is as follows: During operation, the upper and lower sides of the mold can be joined together. Then, the joined mold is placed between two bases 1101. Then, the servo motor 1203 is started to control the drive disk 1204 to rotate. When the drive disk 1204 rotates, the connecting rod 1205 at its end will follow and pull the two support platforms 1201 to slide on the guide rail 1202. At this time, the base 1101 installed on the support platform 1201 will slide along and approach to clamp the mold. Furthermore, a butterfly clamping block 1118 is installed on the ear plate 1102 of the base 1101. The butterfly clamping block 1118 is divided into upper and lower parts, which can clamp the upper and lower side plates of the mold respectively, which is relatively firm.

[0040] To clamp the upper and lower side plates of the mold and keep them tightly fitted, clamps 1106 are installed at both ends of the vertical shaft 1105. The angle of the clamping arm 1104 can be adjusted by rotating the bushing 1103. The clamps 1106 are then placed on the mold. Next, the adjusting bolts 1109 on the clamps 1106 can be adjusted to move the jaws 1108, pressing them tightly against the mold. Through the squeezing and clamping action of the two jaws 1108, the upper and lower side plates of the mold can be fixed together stably, ensuring a continuous overall design during subsequent engraving of characters and patterns. Furthermore, to adjust the clamping arm 1105... After 04, the angle can be limited. After adjusting the angle of the clamping arm 1104, the compression bolt 1112 can be tightened. The compression bolt 1112 can push the sleeve 1113 and the pressure ball 1114 to slide downward. When the pressure ball 1114 slides down, it can squeeze and push the four limiting balls 1115 to slide into the corresponding sliding cavity until they cooperate with the limiting groove 1116 on the inner wall of the roller 1110, thereby restricting the free rotation of the bushing 1103 and facilitating the fixing of the clamping arm 1104. After fixing the mold, the engraving machine 205 can be started and the mold can be processed through the preset program.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
