Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle parts processing technology, specifically a tire mold that avoids glue overflow. Background Technology
[0002] Automotive parts are the various components that make up a car and the products that serve the vehicle. There are many types of automotive parts, and as people's living standards improve, their car consumption is increasing, leading to a growing market for automotive parts. In recent years, automotive parts manufacturers have also developed rapidly. Tires are a crucial part of a car, and they require molds for processing.
[0003] Existing tire molds are prone to glue overflow during the molding process. This glue overflow can affect the quality of the finished tire and cause blockages in the mold gaps and vent holes.
[0004] Therefore, those skilled in the art have provided a tire mold that avoids glue overflow to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to provide a tire mold that avoids glue overflow, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tire mold that avoids glue overflow, comprising a tire mold body, the interior of which is provided with a cavity, an exhaust hole provided on the body and at the highest point of the cavity, a barrier post provided on the exhaust hole, an air guide gap provided on the barrier post, and a push rod provided inside the air guide gap.
[0007] Preferably, the sidewall of the vent hole forms a certain angle with the axis of the barrier column.
[0008] Preferably, the top of the barrier column is provided with a head, the top of the exhaust hole is provided with a receiving groove, and the top of the air guide gap extends into the receiving groove.
[0009] Preferably, a pressing part is provided on one side of the top of the receiving groove, and a ring plate is provided on the head, and the ring plate is provided with a notch that matches the pressing part.
[0010] Preferably, the head is provided with a socket for facilitating the rotation of the blocking column.
[0011] Preferably, one end of the barrier post is provided with a tapered portion.
[0012] Preferably, the head is provided with an air guide hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In this invention, a removable baffle post is installed in the vent hole. The air guide gap in the lower part of the baffle post can easily cut off the overflow glue while ensuring normal venting. Since the gap at the bottom of the baffle post inserted into the vent hole is small, the overflow glue has little impact on the tire when it is twisted off, and the vent hole can be prevented from being blocked.

[0020] 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.
[0021] All electronic components in this application are controlled by an external controller.
[0022] Please see Figures 1-4 In this embodiment of the present invention, a tire mold for preventing glue overflow includes a tire mold body 1. The body 1 has a cavity 2 inside. An exhaust hole 3 is provided on the body 1 and at the highest point of the cavity 2. A barrier post 4 is provided on the exhaust hole 3. An air guide gap 5 is provided on the barrier post 4. A push rod 6 is provided inside the air guide gap 5. The side wall of the exhaust hole 3 forms a certain angle with the axis of the barrier post 4.
[0023] The body 1 is a common tire mold on the market. The cavity 2 is located inside the body 1. The vent 3 is opened at the highest point of the cavity 2 to facilitate the venting of the glue during the injection process. The side wall of the vent 3 forms a certain angle with the vertical plane. The angle is preferably one degree. This makes the vent 3 form a platform shape that is wider at the top and narrower at the bottom. The barrier post 4 is inserted into the vent 3. The air guide gap 5 is opened on the barrier post 4. The air guide gap 5 can divide the middle and lower part of the barrier post 4 into two halves. When the two halves of the barrier post 4 are inserted into the platform-shaped vent 3, the ends of the two halves of the barrier post 4 will approach each other, which will reduce the air guide gap 5. The push rod 6 is placed at the top of the air guide gap 5. When the barrier post 4 is pulled out, the push rod 6 can move downward to remove the overflow glue in the air guide gap 5.
[0024] In one embodiment, specifically, the top of the barrier post 4 is provided with a head 7, the top of the exhaust hole 3 is provided with a receiving groove 8, and the top end of the air guide gap 5 extends into the receiving groove 8; one end of the barrier post 4 is provided with a tapered portion 13; the head 7 is provided with an air guide hole 14, the head 7 is located at the top of the barrier post 4, the receiving groove 8 is opened at the top of the exhaust hole 3, the tapered portion 13 is located at the bottom end of the barrier post 4, which can be easily inserted into the exhaust hole 3, the air guide hole 14 is opened on the head 7, the air guide hole 14 communicates with the air guide gap 5 to improve the exhaust effect, and the head 7 can be placed in the receiving groove 8 to facilitate the fixation of the barrier post 4.
[0025] The receiving groove 8 has a pressing part 9 on one side of its top, and a ring plate 10 on its head 7. The ring plate 10 has a notch 11 that matches the pressing part 9. The pressing part 9 is integrally formed with the receiving groove 8, and the ring plate 10 is integrally formed with the head 7. The notch 11 is opened on one side of the ring plate 10. Rotating the head 7 can screw the ring plate 10 into the lower part of the pressing part 9, which facilitates the fixing and detachment of the blocking column 4.
[0026] Based on the above embodiments, specifically, the head 7 is provided with a socket 12 for facilitating the rotation of the barrier post 4. The socket 12 is opened on the head 7, and tools such as a hex wrench can be used to rotate the barrier post 4, which facilitates the installation and separation of the barrier post 4.
[0027] When in use, insert the barrier post 4 into the vent hole 3 and rotate the head 7 to press the pressing part 9 against the ring plate 10. Then, the mold body 1 can be used to mold the tire. During the injection process, excess rubber material will overflow through the vent hole 3. After molding is completed, rotate the barrier post 4 to separate it from the vent hole 3. Since the air guide gap 5 is wider at the top and narrower at the bottom, the rubber in the air guide gap 5 will be twisted off and separated from the molded tire during the rotation. After the barrier post 4 is removed, move the push rod 6 downward to push out the overflowing rubber in the air guide gap 5.
[0028] 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.
