Description

Technical Field

[0001] This utility model relates to the field of tire mold technology, specifically a tire limiting and pressing mold equipment. Background Technology

[0002] In the tire manufacturing process, the limiting and pressing mold is the core equipment for achieving precise tire forming and performance optimization. It is mainly used in tire vulcanization, inner liner bonding, and bead shaping.

[0003] Currently, in the existing technology, during the tire inflation and shaping process, the tire is generally placed in the lower mold first, and then the upper mold descends to abut against the lower mold to limit the tire. Then, the tire is inflated, causing it to expand. With the cooperation of the upper and lower molds, the tire is shaped. However, for tires of different sizes, the height at which the upper mold descends to abut against the lower mold is different due to the different molds. Therefore, the descent stroke of the upper mold is different, and the process of accurately controlling the descent stroke of the upper mold is complex. In view of this, a tire limiting inflation mold device is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a tire limiting and pressing mold device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a tire limiting and inflating mold device, comprising a base frame and an inflation head for inflating the tire. An mounting plate is fixedly installed on the upper side of the base frame, and a lower mold is detachably connected to the mounting plate via bolts. A vertical rod is fixedly installed on the base frame, and a lower mold assembly is disposed above the lower mold. The lower mold assembly includes: A top plate, which is fixedly connected to a vertical rod, and an electric cylinder is fixedly installed on the top plate; A connection protection component is provided, which is disposed at the output end of the electric cylinder; A guide rod is provided below the connecting protective assembly, and the guide rod is detachably connected to the upper mold by bolts.

[0006] Preferably, the connection protection assembly includes a horizontal plate, which is fixed to the output end of the electric cylinder. The horizontal plate is penetrated by a round rod and slidably connected to the round rod. A cylinder is fixedly connected to the bottom of the round rod, and a limit ring is fixedly connected to the top of the round rod. The limit ring is elastically connected to the horizontal plate by a return spring.

[0007] Preferably, a limit switch is fixedly connected to the upper side of the guide rod. The guide rod descends through the output end of the electric cylinder, thereby driving the horizontal plate to descend, so that the guide rod and the upper mold descend. When the upper mold and the lower mold abut against each other, the output end of the electric cylinder continues to descend, the horizontal plate continues to descend, the return spring is stretched, and when the horizontal plate is limited by the cylinder, the horizontal plate abuts against the limit switch, so that the electric cylinder closes.

[0008] Preferably, the diameter of the cylinder is larger than the diameter of the rod, and when the limit switch abuts against the horizontal plate, the top of the cylinder abuts against the horizontal plate.

[0009] Preferably, a guide groove is provided on the outer wall of the vertical rod.

[0010] Preferably, the guide groove matches the guide rod, and the use of the guide groove enables the upper mold to descend stably and make stable contact with the lower mold.

[0011] Preferably, the bottom of the lower mold has a through hole for the tire inflation head to pass through. After the inflation head is connected to the inflation head, the tire can be inflated.

[0012] This utility model provides a tire limiting and inflating mold device. It has the following beneficial effects: (1) The tire limiting and pressing mold equipment drives the horizontal plate to drive the guide rod and the upper mold to descend through the electric cylinder. When the upper and lower molds come into contact, the electric cylinder continues to run. The reset spring is stretched so that the horizontal plate contacts the limit switch to trigger the stop. There is no need to manually set the stroke parameters. The mechanical limit and the electric cylinder linkage automatically match the pressing requirements of different tires, avoiding the cumbersome operation of traditional equipment that relies on manual input of the stroke, and significantly reducing the debugging difficulty and the risk of misoperation.

[0013] (2) The tire limiting and pressing mold equipment forms a vertical guiding path through the cooperation of the vertical rod guide groove and the guide rod, ensuring the straightness of the upper mold when it descends. At the same time, the upper mold and the lower mold can be disassembled and replaced, which is convenient for pressing and shaping different tires. Attached Figure Description

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model proposes a tire limiting and inflating mold device, including a base frame 1 and an inflation head 6 for inflating the tire. An mounting plate 2 is fixedly installed on the upper side of the base frame 1. A lower mold 3 is detachably connected to the mounting plate 2 by bolts. A vertical rod 4 is fixedly installed on the base frame 1. A lower mold assembly 5 is arranged above the lower mold 3. The lower mold assembly 5 includes a top plate 51, a connecting and protective assembly 53, and a guide rod 54. The top plate 51 is fixedly connected to the vertical rod 4. An electric cylinder 52 is fixedly installed on the top plate 51. The connecting and protective assembly 53 is arranged on the output end of the electric cylinder 52. The guide rod 54 is arranged below the connecting and protective assembly 53. The guide rod 54 is detachably connected to the upper mold 55 by bolts. By activating the electric cylinder 52, the output end of the electric cylinder 52 can drive the connecting and protective assembly 53 to move, thereby allowing the upper mold 55 to descend and abut against the lower mold 3.

[0020] In this embodiment of the utility model, in order to prevent the upper mold 55 from excessively squeezing the lower mold 3, the connecting protective component 53 includes a horizontal plate 531. The horizontal plate 531 is fixed to the output end of the electric cylinder 52. The horizontal plate 531 is penetrated by a round rod 533 and is slidably connected to the round rod 533. A cylinder 532 is fixedly connected to the bottom of the round rod 533, and a limit ring 534 is fixedly connected to the top of the round rod 533. The limit ring 534 is elastically connected to the horizontal plate 531 by a return spring. A limit switch 535 is fixedly connected to the upper side of the guide rod 54. The diameter of the cylinder 532 is larger than the diameter of the round rod 533. When cylinder 532 abuts against the horizontal plate 531, the top of cylinder 532 abuts against the horizontal plate 531. The output end of electric cylinder 52 extends, and the horizontal plate 531 drives the guide rod 54 and the upper mold 55 to descend. When the upper mold 55 abuts against the lower mold 3, electric cylinder 52 continues to run, and the horizontal plate 531 continues to descend. The return spring is stretched, causing the horizontal plate 531 to contact the limit switch 535 and trigger the machine to stop. There is no need to manually set the stroke parameters. The mechanical limit and the linkage of electric cylinder 52 automatically match the pressing requirements of different tires, avoiding the cumbersome operation of traditional equipment that relies on manual input of stroke, and significantly reducing the difficulty of debugging and the risk of misoperation.

[0021] Furthermore, the guide groove 41 matches the guide rod 54. Through the use of the guide groove 41, the upper mold 55 can descend stably, preventing the upper mold 55 from deviating.

[0022] Furthermore, the bottom of the lower mold 3 is provided with a through hole 31 for the tire inflation head to pass through. The use of the through hole 31 will not affect the subsequent inflation and shaping of the tire. After the inflation head is connected to the inflation head 6, the tire can be inflated and shaped in conjunction with the use of the upper mold 55 and the lower mold 3.

[0023] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0024] In use, the tire is first placed in the lower mold 3. At the same time, the tire inflation head is connected to the inflation head 6 through the through hole 31. Then, the electric cylinder 52 is started, and the output end of the electric cylinder 52 descends. The horizontal plate 531 drives the guide rod 54 and the upper mold 55 to descend. When the upper mold 55 abuts against the lower mold 3, the electric cylinder 52 continues to run, and the horizontal plate 531 continues to descend. The return spring is stretched, causing the horizontal plate 531 to contact the limit switch 535 and trigger the stop. Then, gas enters through the inflation head 6 to inflate the tire. Under the limiting action of the upper mold 55 and the lower mold 3, the tire can be shaped.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
