DETAILED DESCRIPTION

[0021] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0022] The special mold for the seat rubber pad of motorcycle and electric vehicle of the utility model is described in detail below with reference to the accompanying drawings. Example

[0023] For easier understanding, see Figures 1 to 6 The utility model provides an embodiment of a special mold for a motorcycle and electric vehicle seat cushion rubber pad, which includes a lower mold 1 and an upper mold 2, and the seat cushion base plate 3 is located between the lower mold 1 and the upper mold 2. The top of the lower mold 1 has a positioning lower mold 11, and the bottom of the upper mold 2 has a positioning upper mold 21, and the positioning lower mold 11 and the rubber pad injection groove 12 respectively match the top and bottom of the positioning lower mold 11. The top of the lower mold 1 is provided with a plurality of rubber pad injection grooves 12, and the plurality of rubber pad injection grooves 12 are used to injection-mold a plurality of rubber pads 4 on the seat cushion base plate 3.

[0024] It should be noted that the mold consists of a lower mold 1 and an upper mold 2. During the injection molding process, the seat cushion base 3 is placed between the lower mold 1 and the upper mold 2. A positioning lower mold 11 is designed at the top of the lower mold 1, while a corresponding positioning upper mold 21 is installed at the bottom of the upper mold 2. This ensures that the upper and lower molds are accurately aligned when the molds are closed, thus ensuring production accuracy.

[0025] In some embodiments, a plurality of mold positioning columns 13 are fixedly connected to the top of the lower mold 1 , and a plurality of mold positioning grooves 23 corresponding to the mold positioning columns 13 are formed on the bottom of the upper mold 2 .

[0026] It should be noted that to further improve the fit between the molds, several mold locating posts 13 are fixedly connected to the top of the lower mold 1. These posts correspond one-to-one with the mold locating slots 23 provided on the bottom of the upper mold 2. When the upper mold 2 descends and closes with the lower mold 1, the mold locating posts 13 insert into the corresponding mold locating slots 23, ensuring a tight fit between the upper and lower molds and preventing shifting or misalignment during the injection molding process.

[0027] In some embodiments, a through injection hole 22 is opened on the top of the upper mold 2, and the injection hole 22 is connected to the injection groove at the bottom of the upper mold 2, and the injection groove is connected to the position on the seat cushion bottom plate 3 where the rubber pad 4 is injected.

[0028] It should be noted that the top of the upper mold 2 is provided with a through-injection hole 22, which directly connects to the injection groove at the bottom of the upper mold 2 and ultimately extends to a predetermined position on the seat cushion base plate 3. Through this injection hole 22, molten rubber or other material can be smoothly injected into the pre-set rubber pad injection groove 12, thereby forming the desired rubber pad 4.

[0029] In some embodiments, five rubber pads 4 are formed on the seat cushion bottom plate 3 by injection molding.

[0030] It should be noted that five rubber pads 4 are formed on the seat base 3 through an injection molding process. These five rubber pads 4 are distributed in different parts of the seat to meet the rider's needs for comfort and support. The specific distribution pattern can be adjusted according to actual design requirements.

[0031] In some embodiments, the seat cushion bottom plate 3 is made of metal or plastic.

[0032] It should be noted that the seat cushion base plate 3 can be made of two different materials: metal or plastic. If metal is selected as the base plate material, the structural strength and durability of the entire seat cushion can be enhanced;

[0033] Using plastic is more conducive to reducing weight and cost. Regardless of the material, it must have good thermal stability to withstand the high temperatures during the injection molding process without deformation.

[0034] Working Principle: First, place the lower mold 1 on the workbench of the injection molding machine and ensure it is level. Then, place the pre-prepared seat cushion base plate 3 steadily on top of the lower mold 1, ensuring that each part of the base plate accurately aligns with the rubber pad injection groove 12 at the top of the lower mold 1. Next, hoist or move the upper mold 2 above the lower mold 1, aligning the upper positioning die 21 at the bottom of the upper mold 2 with the lower positioning die 11 at the top of the lower mold 1. At the same time, ensure that the mold positioning groove 23 at the bottom of the upper mold 2 corresponds one-to-one with the mold positioning column 13 at the top of the lower mold 1.

[0035] When the upper mold 2 descends and contacts the lower mold 1, the mold locating posts 13 engage with the corresponding mold locating slots 23, ensuring precise alignment between the upper and lower molds. This positioning mechanism effectively prevents mold shifting or misalignment during the injection molding process, ensuring the precision of the rubber pad 4 molding.

[0036] The upper mold 2 continues to descend until it is completely closed and fits tightly with the lower mold 1. At this point, a sealed cavity is formed inside the mold, ready for the subsequent injection molding process.

[0037] The injection molding machine injects molten rubber or other elastic materials into the mold through the injection hole 22 at the top of the upper mold 2. The injection hole 22 is directly connected to the injection grooves at the bottom of the upper mold 2, which are in turn connected to the rubber pad injection groove 12 at the top of the lower mold 1.

[0038] The molten material flows along the injection groove, gradually filling each rubber pad injection groove 12. Because the design of the rubber pad injection grooves 12 matches the predetermined locations on the seat cushion base 3, the material solidifies at these locations to form five independent rubber pads 4. Each rubber pad 4 is evenly distributed across the entire seat cushion base 3, providing good support and comfort.

[0039] After the injection molding is completed, the mold remains closed for a period of time so that the molten material can be fully cooled and solidified in the rubber pad injection molding groove 12. The cooling time depends on the type and thickness of the material used, and usually takes several minutes to more than ten minutes.

[0040] When the rubber pad 4 is completely solidified, the mold opening mechanism of the injection molding machine slowly lifts the upper mold 2 to separate it from the lower mold 1. At this time, the seat cushion base plate 3 with the newly formed rubber pad 4 can be taken out from the lower mold 1, completing a complete injection molding cycle.

[0041] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
