Description

Technical Field

[0001] This utility model relates to the technical field of tire molds, specifically a tire mold with multi-angle air channels. Background Technology

[0002] Tire molds are used for vulcanizing and molding various types of tires. During tire production, gas can easily be generated inside the mold, affecting the tire's forming process. Therefore, venting valves are often used to release this gas. Currently, most tire molds utilize vertical air channels.

[0003] A tire mold exhaust valve, published in Chinese Patent Publication No. CN222096704U, includes a lower mold and an exhaust device. An upper mold is disposed on the upper surface of the lower mold. A first limiting block is fixedly connected to the side of the lower mold, and a second limiting block is fixedly connected to the side of the upper mold. An inlet is fixedly connected to the upper surface of the upper mold. The exhaust device is disposed on the surface of the upper mold and includes an exhaust pipe and an exhaust hole. The exhaust pipe is fixedly connected to the surface of the upper mold, and the exhaust hole is opened on the inner wall of the exhaust pipe.

[0004] In the above scheme, the gas is discharged from the mold through the exhaust pipe, exhaust hole, limit frame, fiber ball, slide bar, limit block, first spring and stop block, which leads to the following disadvantages: the exhaust hole angle on the tire mold is uniform, which leads to local gas accumulation and prolongs the exhaust time. Utility Model Content

[0005] The purpose of this invention is to provide a tire mold with multi-angle air channels to solve the problem that the exhaust hole angle on the tire mold is single, which leads to local air accumulation and prolongs the exhaust time.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a tire mold with multi-angle air channels, including an upper mold, the upper mold being detachably mounted on the top surface of a lower mold, the top surface of the upper mold being connected to and fixed with a feed inlet, a plurality of vent holes being opened on all four sides of the outer wall of the upper mold, a plurality of vent pipes being fixed on all four sides of the outer wall of the upper mold, the included angle between any two adjacent vent pipes being 45 degrees, the plurality of vent pipes corresponding to the plurality of vent holes respectively, and each of the plurality of vent pipes being provided with an vent valve.

[0007] Preferably, the lower mold has fixing plates fixed to its front and rear sides, and the top surfaces of the two fixing plates have connecting holes, and the outer sides of the two fixing plates have fixing holes. The upper mold has mounting plates fixed to its front and rear sides, and the bottom surfaces of the two mounting plates have mounting columns fixed. The two mounting columns are detachably installed in the two connecting holes, and the outer sides of the two mounting columns have fixing grooves. Insert shafts are slidably inserted into the two fixing holes, and the two insert shafts are slidably inserted into the two fixing grooves. The outer ends of the two insert shafts are fixed with blocks, and springs are fixed between the two blocks and the two fixing plates. The two springs are respectively wrapped around the two insert shafts.

[0008] Preferably, a first magnet is fixed to the inner end of each of the two insert shafts, and a second magnet is fixed in each of the two fixing slots, with the two second magnets magnetically attracted to the two first magnets.

[0009] Preferably, the inner walls of the two connecting holes are provided with sliding grooves on the left and right sides, and the two mounting columns are fixed with sliders on the left and right sides, and the two sliders are slidably disposed in the two sliding grooves.

[0010] Preferably, the inner walls of the two grooves and the outer walls of the two sliders are both arc-shaped.

[0011] Preferably, the top surface of the lower mold is provided with a sealing groove, and the bottom surface of the upper mold is fixed with a sealing ring, the sealing ring being interference-fitted with the sealing groove.

[0012] Compared with existing technologies, a tire mold with multi-angle air channels that adopts the above technical solution has the following beneficial effects: 1. In use, through the coordinated action of the upper mold, lower mold, feed port, vent hole, vent pipe and vent valve, a multi-angle and multi-position channel layout is achieved, reducing gas retention, avoiding local gas accumulation, shortening venting time and improving production efficiency. Second, during use, the insert shaft automatically resets, allowing it to slide precisely into the fixed slot, effectively and securely connecting the upper and lower molds. This prevents the two molds from separating due to vibration or other reasons during use, thus avoiding impact on production quality. Moreover, the entire operation requires no additional tools, making it simple and convenient, saving mold closing time and improving work efficiency. This magnetic attraction further secures the insert shaft, enhancing the stability of the connection between the upper and lower molds. Thirdly, during use, the cooperation between the slide groove and the slider acts as a limit, avoiding the problem of loose mold closing caused by the misalignment of the mounting post insertion position, thus improving the accuracy and stability of mold closing. The arc-shaped design makes the slider slide more smoothly and naturally within the slide groove, reducing friction and resistance during the sliding process and lowering the operational difficulty when inserting the mounting post into the connecting hole. Because the two parts use an interference fit, the sealing effect is extremely reliable, effectively preventing material leakage from the contact surface between the two molds during tire mold use, ensuring stable internal pressure and material molding quality.

Detailed Implementation

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-3 As shown, a tire mold with multi-angle air channels includes an upper mold 1, which is detachably mounted on the top surface of a lower mold 2. The top surface of the upper mold 1 is connected to and fixed with an inlet 3. Several vent holes 4 are opened on all four sides of the outer wall of the upper mold 1. Several vent pipes 5 are fixed on all four sides of the outer wall of the upper mold 1. The included angle between any two adjacent vent pipes 5 is 45 degrees. The several vent pipes 5 correspond to the several vent holes 4 respectively. Each of the several vent pipes 5 is provided with an vent valve 6.

[0020] During use, the staff first securely installs the upper mold 1 on the top surface of the lower mold 2, ensuring that the two fit tightly together. Then, the material is slowly and evenly poured into the mold through the inlet 3 for shaping. In this crucial step of filling, gas will inevitably be generated inside the mold. At this time, the gas will quickly enter the several vent holes 4 opened on the four sides of the outer wall of the upper mold 1. The staff only needs to open the vent valve 6 in time, and the gas will be smoothly discharged through the vent pipe 5 corresponding to the vent hole 4.

[0021] On the one hand, it effectively solves the problem of gas emission inside the mold, avoiding the troublesome situation in traditional equipment where poor gas emission during filling of the mold leads to a large amount of material flowing out through the vent hole 4, resulting in material waste. This improves the practicality of the equipment and reduces production costs. On the other hand, the included angle between each pair of adjacent vent pipes 5 is carefully set to 45 degrees, and each corresponds precisely to several vent holes 4, so that the included angle between each pair of adjacent vent holes 4 is also 45 degrees. This multi-angle, multi-position channel layout reduces the retention of gas inside the mold, effectively shortens the venting time, and thus improves the overall production efficiency, providing a strong guarantee for the efficient production of tires.

[0022] Through the coordinated action of the upper mold 1, lower mold 2, feed port 3, vent hole 4, vent pipe 5 and vent valve 6, a multi-angle and multi-position channel layout is achieved, reducing gas retention, avoiding local gas accumulation, shortening venting time and improving production efficiency.

[0023] like Figures 1-4 As shown, the lower mold 2 has fixing plates 7 fixed on the front and rear sides of its outer wall. The top surfaces of the two fixing plates 7 are provided with connecting holes 8, and the outer sides of the two fixing plates 7 are provided with fixing holes 9. The upper mold 1 has mounting plates 10 fixed on the front and rear sides of its outer wall. The bottom surfaces of the two mounting plates 10 are provided with mounting posts 11. The two mounting posts 11 are detachably installed in the two connecting holes 8. The outer sides of the two mounting posts 11 are provided with fixing grooves 12. Insert shafts 13 are slidably inserted into the two fixing holes 9. The two insert shafts 13 are slidably inserted into the two fixing grooves 12. The outer ends of the two insert shafts 13 are fixed with blocks 14. Springs 15 are fixed between the two blocks 14 and the two fixing plates 7. The two springs 15 are respectively wrapped around the two insert shafts 13.

[0024] In use, when the operator prepares to close the upper mold 1 and the lower mold 2, the stop block 14 is first pulled outward. This action causes the insertion shaft 13 to move outward as well. During this process, the spring 15 is stretched, generating elastic potential energy. Then, the upper mold 1 is placed stably on the top surface of the lower mold 2, while ensuring that the mounting post 11 is inserted into the connecting hole 8. After the insertion is completed, the stop block 14 is released. At this time, the spring 15, which is in a stretched state, automatically resets the insertion shaft 13 by its own elasticity, so that it is accurately slidably inserted into the fixing groove 12. This effectively and stably connects the upper mold 1 and the lower mold 2, preventing the two molds from separating due to vibration or other reasons during mold use, which would affect production quality. Moreover, the entire operation does not require the use of additional tools, is simple and convenient, saves mold closing time, and improves work efficiency.

[0025] like Figure 2 and Figure 4 As shown, the inner ends of the two insert shafts 13 are each fixed with a first magnet 16, and the two fixing slots 12 are each fixed with a second magnet 17. The two second magnets 17 are magnetically attracted to the two first magnets 16. The inner walls of the two connecting holes 8 are provided with sliding grooves 18 on the left and right sides. The two mounting posts 11 are each fixed with sliders 19 on the left and right sides. The two sliders 19 are slidably arranged in the two sliding grooves 18.

[0026] During use, when the insert shaft 13 is smoothly inserted into the fixing groove 12, the first magnet 16 and the second magnet 17 approach each other and generate magnetic attraction. This magnetic attraction further fixes the insert shaft 13, improving the stability of the connection between the upper mold 1 and the lower mold 2. When the operator inserts the mounting post 11 into the connecting hole 8, the slider 19 slides into the slide groove 18 as the mounting post 11 is inserted. The cooperation between the slide groove 18 and the slider 19 can play a limiting role, avoiding the problem of loose mold closing caused by the deviation of the insertion position of the mounting post 11, thus improving the accuracy and stability of mold closing.

[0027] like Figures 1-4 As shown, the inner walls of the two grooves 18 and the outer walls of the two sliders 19 are both arc-shaped. A sealing groove 20 is provided on the top surface of the lower mold 2, and a sealing ring 21 is fixed on the bottom surface of the upper mold 1. The sealing ring 21 and the sealing groove 20 are interference fit.

[0028] During use, when the mounting post 11 is inserted into the connecting hole 8, the slider 19 slides along the arc-shaped groove 18. The arc design makes the slider 19 slide more smoothly and naturally within the groove 18, reducing friction and resistance during the sliding process and lowering the operational difficulty when inserting the mounting post 11 into the connecting hole 8. When the lower mold 2 and the upper mold 1 are closed, the sealing ring 21 is tightly embedded in the sealing groove 20. Because the two are press-fitted, the sealing effect is extremely reliable, effectively preventing material leakage from the contact surface of the two molds during tire mold use, ensuring stable internal pressure and material molding quality.

[0029] 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.
