Background Art

In the process of tire processing and manufacturing, there are roughly six steps from raw materials to finished products, including rubber mixing, material preparation, molding, vulcanization, inspection and packaging, and periodic testing. In the process of tire molding, special molds are required to complete the shaping work, so that the processed tires meet the expected manufacturing effect.

As shown in Fig. 1-5, the present application provides a tire processing molding die, including a base 1, an upper die base 3 and a lower die base 4, the top of the base 1 is fixedly connected to a U-shaped frame 2, the top of the U-shaped frame 2 is provided with a lifting assembly 5, the outer end of the U-shaped frame 2 is fixedly connected to a motor 6, the outer end of the lower die base 4 is fixedly connected to two rotating shafts, both rotating shafts are rotatably connected to the inner side wall of the U-shaped frame 2, the output end of the motor 6 is fixedly connected to one of the rotating shafts, the lower die base 4 is provided with an ejection assembly 9, the inner side wall of the U-shaped frame 2 is provided with a limiting groove 8, and the top of the base 1 is provided with a collecting bucket 7;

The ejection assembly 9 includes a movable ring 91 and an ejection ring 93. A plurality of connecting columns 92 are fixedly connected between the ejection ring 93 and the movable ring 91. A connecting rod 94 is fixedly connected to the outer wall of the movable ring 91. An end of the connecting rod 94 away from the movable ring 91 is rotatably connected to a slider 95 matching the limiting groove 8. The setting of the limiting groove 8 can limit the movement trajectory of the slider 95. The slider 95 is slidably connected to the limiting groove 8.

This solution is used to mold the tire. Specifically, the raw materials are conveyed into the mold cavity formed between the upper mold base 3 and the lower mold base 4, the mold is heated, and a certain temperature and pressure are applied to form the shape and pattern of the tire. Before the pressure is released, the tire is cooled in the mold for a period of time to solidify and stabilize the rubber, and finally the tire is taken out.

Among them, when the mold is cooled after forming, the upper mold base 3 is raised a certain distance by using the lifting component 5 to reserve a certain space for the rotation of the lower mold base 4, and then the lower mold base 4 is controlled by the motor 6 to rotate 180°. During this process, the slider 95 is forced to slide in the limiting groove 8, so that the ejection ring 93 and the lower mold base 4 move relative to each other during the synchronous rotation process. The ejection ring 93 is used to eject the tire for a certain distance to reduce the adhesion of the tire in the mold cavity. After the lower mold base 4 completes the 180° rotation, the tire formed in the lower mold base 4 is automatically unloaded under the action of gravity and falls into the collection bucket 7 for collection.

It should be noted that a feed interface is provided on the upper die base 3 , and an external material feeding device can be connected to the feed interface on the upper die base 3 to realize the injection of raw materials.

As shown in Figures 1-2, the outer wall of the upper mold base 3 is fixedly connected to two connecting blocks 14, and the two connecting blocks 14 are slidably connected to the inner wall of the U-shaped frame 2. The lifting assembly 5 includes a motor 2 51 and two screw rods 53. The motor 2 51 is fixed to the motor 2 51 at the top of the U-shaped frame 2. Two pulleys 1 52 are fixedly connected to the output end of the motor 2 51. The two screw rods 53 are rotatably connected to the U-shaped frame 2, and the tops of the two screw rods 53 are fixedly connected to pulleys 2 54. The pulleys 2 54 are transmission-connected to the pulleys 1 52 through belts 55. The screw rods 53 penetrate the connecting block 14 and are threadedly connected to the connecting block 14. The inner wall of the U-shaped frame 2 is fixedly connected to two support blocks, and the two screw rods 53 are rotatably connected to the two support blocks respectively.

In this embodiment, by starting motor 2 51 and under the transmission action of pulley 1 52 and pulley 2 54, the two screw rods 53 can be driven to rotate, thereby realizing the vertical movement of the upper mold base 3, thereby completing the opening and closing action of the upper mold base 3 and the lower mold base 4.

As shown in FIG4 , the inner walls of the upper die base 3 and the lower die base 4 are provided with a plurality of tooth grooves 11 , a plurality of groups of tooth grooves 2 12 and a plurality of tooth grooves 3 13 . The plurality of tooth grooves 11 and the plurality of tooth grooves 3 13 are distributed equidistantly in a ring shape, and the plurality of groups of tooth grooves 2 12 are respectively located between two adjacent tooth grooves 3 13 .

In this embodiment, the number of a set of tooth grooves 12 is two. By setting the tooth grooves 11, 12 and 13, the tire has large tire teeth, a thick tire width and a stronger grip.

As shown in Figure 4, the interior of the lower mold base 4 is respectively provided with an installation cavity and a placement cavity, the installation cavity and the placement cavity are connected to each other, the movable ring 91 is slidably connected to the installation cavity, the ejection ring 93 is adapted to the placement cavity, and the outer end of the lower mold base 4 is provided with a connecting groove 10 connected to the installation cavity, and the connecting rod 94 passes through the connecting groove 10.

In this embodiment, when the slider 95 slides in the limiting groove 8, under the action of the connecting rod 94, it can drive the movable ring 91 to slide in the installation cavity, and simultaneously drive the ejection ring 93 to move, so that the ejection ring 93 is moved out of the placement cavity, and the molded tire is ejected for a distance, which facilitates the tire unloading work.

As shown in FIG. 3 , the limiting groove 8 is composed of an arc segment and an inclined segment, and the arc segment and the inclined segment are connected to each other.

In this embodiment, when the lower die base 4 rotates and the slider 95 slides in the arc section in the limiting groove 8, the movable ring 91 and the ejector ring 93 will not be displaced relative to the lower die base 4. Since the vertical distance between the end of the arc section in the limiting groove 8 and the central axis of rotation of the lower die base 4 is greater than the vertical distance between the end of the inclined section and the central axis of rotation of the lower die base 4, when the slider 95 slides in the inclined section in the limiting groove 8, the movable ring 91 and the ejector ring 93 will be displaced relative to the lower die base 4.

Working principle:

The upper die holder 3 is controlled to move downward by the lifting assembly 5, so that the upper die holder 3 is in close contact with the lower die holder 4, and the raw materials are transported to the mold cavity formed between the upper die holder 3 and the lower die holder 4 by using an external feeding device, and the mold is heated, and a certain temperature and pressure are applied to form the shape and pattern of the tire. Before the pressure is released, the tire is cooled in the mold for a period of time to solidify and stabilize the rubber. When the mold is cooled, the upper die holder 3 is raised by the lifting assembly 5 to reserve a certain space for the rotation of the lower die holder 4, and then the upper die holder 3 is raised by the motor 6. The lower die base 4 is controlled to rotate 180°. During this process, the slider 95 is forced to slide in the limiting groove 8, so that the ejector ring 93 and the lower die base 4 move relative to each other during the synchronous rotation of the lower die base 4. The ejector ring 93 is used to eject the tire for a distance. After the lower die base 4 completes the 180° rotation, the tire formed in the lower die base 4 is automatically unloaded under the action of gravity and falls into the collection bucket 7 for collection. Subsequently, the motor 6 is used to control the lower die base 4 to reset, and the above operation is repeated to complete the mass production of tires.

The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
