Description

Technical Field

[0001] The utility model relates to the technical field of tire printing molds, in particular to a multi-printing tire mold with shock-absorbing and protective functions. Background Art

[0002] Tire molds are molds used for vulcanization molding of various tires. Tire molds are divided into: flexible molds, which are composed of pattern rings, mold sleeves, upper and lower side panels. Flexible molds are divided into cone-guided flexible molds and inclined plane-guided flexible molds. The two-half molds are composed of upper molds and lower molds.

[0003] In the prior art, during the use of the tire mold, it is necessary to close the mold. When the upper mold and the lower mold are combined, a large impact force will be generated. Most traditional tire molds lack shock-absorbing components. When closing the mold, the mold will be damaged due to the large impact force. Therefore, the utility model proposes a multi-printed tire mold with shock-absorbing and protective functions to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a multi-print tire mold with shock-absorbing and protective functions is proposed. By setting a buffer mechanism, when the mold is closed, the mold core body is pressed and moves downward, pushing four sliders to move in the slide groove, and then squeezing the spring, so that the spring is compressed to achieve a buffering effect, avoiding large impact force and causing damage to the mold core body.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A multi-print tire mold with shock-absorbing and protective functions comprises a base, the upper end of the base is fixedly connected to an outer ring, the inner wall of the outer ring is slidably connected to a movable plate, the upper end of the movable plate is fixedly connected to a mold core body, the upper end of the base is provided with four slide grooves distributed at equal intervals in the circumferential direction, the interiors of the four slide grooves are jointly provided with a buffer mechanism for buffering the mold core body, the buffer mechanism comprises four sliders respectively slidably connected to the four slide grooves, the lower end of the movable plate is fixedly connected to four connecting blocks distributed at equal intervals in the circumferential direction, the four sliders are rotatably connected to the four connecting blocks respectively by rotating rods, and the side walls of the four sliders are elastically connected to the inner walls of the slide grooves on the same side by springs.

[0007] Preferably, four dampers which are circumferentially evenly spaced are fixedly connected to the upper end of the base, and the telescopic ends of the four dampers are fixedly connected to the lower end of the movable plate.

[0008] Preferably, a mold cavity is defined in the mold core body.

[0009] Preferably, four fixing blocks are fixedly connected to the upper end of the outer ring, and the four fixing blocks are distributed at equal intervals in the circumferential direction.

[0010] Preferably, four limit rods are fixedly connected to the upper end of the base, and the four limit rods are distributed at equal intervals in the circumferential direction.

[0011] Preferably, the four limiting rods pass through four fixing blocks respectively and are fixedly connected thereto.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting up a buffer mechanism, when the mold is closed, the upper mold and the lower mold are merged. At this time, the upper mold transmits the impact force to the mold core body, and the mold core body moves downward under pressure, thereby pushing the four fixed blocks to move downward, pushing the four rotating rods to rotate, thereby pushing the four sliders to move in the slide groove, and then squeezing the spring, so that the spring is compressed to achieve a buffering effect, avoiding a large impact force and causing damage to the mold core body.

[0014] 2. By setting a limit rod, a limit hole matching the limit rod needs to be opened at the upper mold. When the mold is closed, the limit rod is inserted into the limit hole to limit the upper mold, thereby achieving a limiting effect, improving the stability of movement, and avoiding deviation when the mold is closed.

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] Reference Figure 1-4 A multi-print tire mold with shock-absorbing and protective functions comprises a base 1, an outer ring 2 is fixedly connected to the upper end of the base 1, a movable plate 6 is slidably connected to the inner wall of the outer ring 2, a core body 3 is fixedly connected to the upper end of the movable plate 6, a mold cavity 12 is provided in the core body 3, four chute 10 circumferentially evenly spaced are provided at the upper end of the base 1, a buffer mechanism for buffering the core body 3 is commonly provided inside the four chute 10, the buffer mechanism comprises four sliders 9 respectively slidably connected to the four chute 10, four connecting blocks 7 circumferentially evenly spaced are fixedly connected to the lower end of the movable plate 6, the four sliders 9 are rotatably connected to the four connecting blocks 7 by rotating rods 8 respectively, and the side walls of the four sliders 9 are elastically connected to the inner walls of the same-side chute 10 by springs 11.

[0022] In the utility model, four dampers 13 are fixedly connected to the upper end of the base 1 and are distributed at equal intervals in the circumferential direction. The telescopic ends of the four dampers 13 are fixedly connected to the lower end of the movable plate 6. By setting the dampers 13, a better shock-absorbing effect can be achieved, and the vibration of the core body 3 can be avoided. After the mold is separated, the core body 3 can quickly return to a stable state.

[0023] In the utility model, the upper end of the outer ring 2 is fixedly connected with four fixing blocks 4, and the four fixing blocks 4 are circumferentially evenly spaced. The upper end of the base 1 is fixedly connected with four limiting rods 5, and the four limiting rods 5 are circumferentially evenly spaced. The four limiting rods 5 pass through the four fixing blocks 4 respectively and are fixedly connected thereto.

[0024] When the utility model is used, when the mold is closed, the upper mold and the lower mold are merged. At this time, the upper mold transmits the impact force to the core body 3, and the core body 3 moves downward under pressure, thereby pushing the four fixed blocks 4 to move downward, pushing the four rotating rods 8 to rotate, thereby pushing the four sliding blocks 9 to move in the slide groove 10, and then squeezing the spring 11, so that the spring 11 is compressed to achieve a buffering effect, avoiding a large impact force and causing damage to the core body 3.

[0025] A limiting hole matching with the limiting rod 5 needs to be provided at the upper mold that cooperates with the device. When the mold is closed, the limiting rod 5 is inserted into the limiting hole to limit the upper mold, thereby achieving a limiting effect, improving the stability of movement, and avoiding displacement when the mold is closed.

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.
