Description

Technical Field

[0001] The utility model relates to the technical field of tire production, in particular to a forming device for a self-foaming material sound insulation layer. Background Art

[0002] A self-foaming sound-absorbing sponge tire with the Chinese patent number CN 116424037 A belongs to the field of tires. It includes two parts: a tire body and a sound-absorbing part. The tire body includes parts such as a tread, a tire sidewall, and an airtight layer; the sound-absorbing part is formed by applying polyurethane to the airtight layer inside the tire cavity, automatically foaming and expanding in the air and crosslinking and curing, and finally obtaining a sound-absorbing sponge tire. The manufacturing method of the present invention is as follows: First, laser clean the airtight layer inside the tire cavity; then, coat the foaming material on the airtight layer, automatically foam and expand and crosslink and cure in a mold, and let it stand to obtain a sound-absorbing sponge tire. The present invention aims to provide a self-foaming sound-absorbing sponge tire with good sound-absorbing performance, simple production process, high efficiency, and excellent durability of the foaming material.

[0003] The existing self-foaming sound-absorbing sponge tire has good sound-absorbing performance, simple production process, high efficiency, and excellent durability of the foaming material, and solves the problem that the sponge head and tail joint part of the existing sound-absorbing sponge tire is an obvious weak point. The sponge is pasted on the airtight layer on the inner wall of the tire through an adhesive. If the sponge joint is not treated, the sponge is likely to fall off from the head and tail joints when the tire travels more than 20,000 kilometers; if the sponge joint is treated, it is necessary to manually stick the head and tail joints of the sponge together with an adhesive first, which is difficult to achieve automated production and has low production efficiency. However, there are still the following problems in actual use: 1. When the self-foaming material foams inside the tire, the sponge body is not restricted, so the direction of spontaneous expansion of the sponge, as well as the range of foaming thickness and width, are uncontrollable. Therefore, a forming device for a self-foaming material sound insulation layer is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the self-foaming material foams inside the tire in the prior art, the foaming and forming are not restricted, so the direction of spontaneous expansion of the foaming material, as well as the range of foaming thickness and width, are uncontrollable, and a forming device for a self-foaming material sound insulation layer is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A forming device for a self-foaming material sound insulation layer, including a tire placement table, a tire body, a shaping support table, and a foaming mold. A support holder is clamped on the top of the tire placement table, the support holder clamps the tire body, the foaming material is smeared inside the tire body, tire bead seats are opened at both the top and the bottom inside the tire body, the shape of the tire bead seat is arc-shaped, and the foaming mold is provided with a material injection port.

[0006] Preferably, a longitudinal movement component is installed on the top of the shaping support platform, and the bottom end of the longitudinal movement component is connected to a transverse movement component.

[0007] Preferably, the other end of the longitudinal movement component is connected to a connecting bracket, and one end of the connecting bracket is clamped with a pressing plate.

[0008] Preferably, the shape of the foaming mold is hollow inside and matches the designed shape, and the inside of the foaming mold and the tire body are mutually adapted.

[0009] Preferably, the back surface of the foaming mold and the tire bead inside the tire body are mutually clamped, or a tire bead pulling device is provided to be mutually adapted, so that the foaming mold can enter the tire body part.

[0010] Preferably, an opening is formed inside the foaming mold, and the internal space of the opening is for the foaming of the foaming material.

[0011] Preferably, the foaming material is applied to the airtight layer inside the tire cavity, and the foaming material is directly and automatically foamed and cured inside the tire.

[0012] Beneficial effects

[0013] In the present utility model, the foaming material is used inside the tire body. When processing the tire, the tire body is placed on the tire placement platform and clamped by the support clamping frame to limit the tire body. The components on the plastic support platform are mainly used to limit the foaming material, ensuring that the foaming width and foaming thickness of the foaming material are within a reasonable range.

[0014] In the present utility model, after the foaming mold is placed inside the tire body, raw materials are injected from the injection port. The injection port penetrates the inside, and the injected raw materials will directly enter the tire body and slowly fall while directly adhering to the inner surface wall of the tire body. The foaming mold body can limit the foaming material, making the forming of the soundproof material more stable and the finished product more stable. Description of the drawings

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor all fall within the protection scope of the present utility model.

[0023] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific Embodiment 1:

[0025] Refer to Figures 1-5 , a forming device for a self-foaming material sound insulation layer, including a tire placement table 1, a tire body 2, a shaping support table 10 and a foaming mold 5. A support bracket 3 is clamped on the top of the tire placement table 1, the support bracket 3 clamps the tire body 2, the inside of the tire body 2 is coated with a foaming material 12, both the top and bottom inside the tire body 2 are provided with beads 11, the shape of the beads 11 is arc-shaped, a feeding port 8 is provided on one side of the front of the tire body 2, an opening 13 is provided inside the foaming mold 5, and the internal space of the opening 13 is for foaming the foaming material.

[0026] First, the foaming material 12 inside the tire body 2 uses a foaming material. It should be noted that the tire body 2 in this utility model is a spliced tire, so the shape of the foaming mold 5 is also the same. When applied to a complete tire, only a foaming mold 5 with the same function and a complete circular ring shape needs to be set. When processing the tire, the tire body 2 is placed on the tire placement table 1 and clamped by the support bracket 3 to limit the tire body 2.

[0027] A longitudinal movement component 4 is installed on the top of the shaping support table 10, and the bottom end of the longitudinal movement component 4 is connected to a transverse movement component 7.

[0028] The components on the plastic support platform 10 are mainly used to restrict the foaming material 12, ensuring that the foaming width and thickness of the foaming material 12 are within a reasonable range. Among them, the longitudinal movement component 4 is mainly used to control the lifting of the foaming spraying mechanism. When the longitudinal movement component 4 descends and the abutment plate 6 aligns with the tire bead of the tire body 2, the descent can be stopped. Then, the transverse movement component 7 is used to control the forward extension of the front abutment plate 6.

[0029] It should be noted that both the transverse movement component 7 and the longitudinal movement component 4 are complete servo motor drive modules.

[0030] The other end of the transverse movement component 7 is connected with a connecting bracket 9. One end of the connecting bracket 9 is clamped with an abutment plate 6. It should be noted that the whole abutment plate 6 can rotate. Specific Embodiment Two:

[0032] Refer to Figure 5 , the difference between the solution of this embodiment and the first specific embodiment lies in that the tire body 2 is longitudinally placed, and the foaming mold 5, the transverse movement component 7, and the longitudinal movement component 4 are all horizontally installed.

[0033] Before the abutment plate 6 extends forward, first place the foaming mold 5 into the tire body 2. The shape of the foaming mold 5 shown in the figure is arc-shaped and can be applied to a complete circular tire body 2. That is, first restrict the foaming material 12 of a part of the tire arc length, and then successively restrict the remaining foaming material 12 of the tire arc length. For the convenience of installation, a manipulator can be installed on the tire placement table 1 to install the foaming mold 5. The back of the foaming mold 5 will be dimensionally matched with the bead 11 inside the tire body 2. When the foaming mold 5 is in place and reaches the set distance position from the tire airtight layer, start to control the forward extension of the abutment plate 6 and rotate the foaming mold 5 at an angle. Inject the raw material from the injection port 8. The injection port 8 penetrates internally, and the injected raw material will directly enter the tire body 2 and slowly fall directly against the inner wall of the tire body 2. The body of the foaming mold 5 can restrict the width of the foaming material 12. After the abutment plate 6 extends forward, it will fit against the outside of the foaming mold 5 and directly enter the foaming mold 5 to restrict the foaming thickness. Specific Embodiment Three:

[0035] A process for a self-foaming material sound insulation layer forming device, the process comprising the following steps:

[0036] Sp1. Load the tire;

[0037] Sp2. Limit the tire;

[0038] Sp3. Inject self-foaming material into the foaming mold;

[0039] Sp4. Form and remove the tire.

[0040] The process of injecting self - foaming material into the inner wall of the tire includes a dragging forming method, a mold clamping forming method, or a combination of the two. Any one of the three can be selected according to the actual process conditions, and the appropriate process can be chosen according to the actual process situation. The dragging speed can be uniform or programmed with segmented dragging speeds, and the appropriate speed can be selected according to the actual working conditions (including foaming speed, ambient temperature and humidity, etc.). Mold clamping forming means using a mold to restrict the material in the foaming area, so that the overall shape of the foaming material is the shape restricted by the mold, thereby making the forming shape of the sound - proof material inside the tire better and forming a block - shaped foaming block. At the same time, the two methods can also be combined. First, a polyurethane forming block is fixed (as the starting and ending points of the whole), and then it is dragged to form the whole polyurethane sound - proof cotton strip. Other materials can also be used for the foaming material as long as the foaming forming inside the tire is achieved.

[0041] To sum up:

[0042] 1. For the foaming material 12 in the tire body 2, a foaming material is used. It should be noted that the tire body 2 in this utility model is a spliced tire, so the shape of the foaming mold 5 is also the same. When applied to a complete tire, only a foaming mold 5 with the same function and a complete circular - ring shape needs to be set. When processing the tire, the tire body 2 is placed on the tire placement table 1 and clamped by the support bracket 3 to limit the tire body 2. The components on the plastic support table 10 are mainly used to restrict the foaming material 12 to ensure that the foaming width and foaming thickness of the foaming material 12 are within a reasonable range.

[0043] 2. The back of the foaming mold 5 will be clamped with the bead 11 inside the tire body 2. After clamping, start to control the forward extension of the pressing plate 6 and form the required angle with the inner wall of the tire. When the foaming mold 5 is placed inside the tire body 2, raw materials are injected from the injection port 8. The injection port 8 runs through the inside, and the injected raw materials will directly enter the tire body 2 and slowly fall while directly sticking to the inner surface of the tire body 2. The body of the foaming mold 5 can restrict the width of the foaming material 12. After the pressing plate 6 extends forward, it will fit with the outside of the foaming mold 5, and the mold will directly enter the foaming mold 5 to restrict the foaming thickness.
