Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, and in particular to a vulcanizing machine for rubber products. Background Technology

[0002] A vulcanizing machine is a device used for vulcanizing various rubber products. Vulcanization is the process of adding vulcanizing agents and crosslinking aids such as accelerators to rubber, and transforming the linear macromolecules of rubber into a three-dimensional network structure under certain temperature and pressure conditions. Vulcanization is named after the early use of sulfur as a crosslinking agent in the production of natural rubber products. The two hot plates of the vulcanizing machine should have parallel pressure surfaces. The hot plates are heated by steam or electricity.

[0003] However, most vulcanizing machines currently in use have a structure consisting of only one upper and lower mold, resulting in low processing efficiency. To improve efficiency, multi-layer rubber vulcanizing machines have emerged. However, when using multi-layer rubber vulcanizing machines, the molds need to be closed sequentially from bottom to top, and the time spent on mold opening and closing also affects processing efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a rubber product vulcanizing machine with stable structure, capable of simultaneous mold opening and closing, and high efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A rubber product vulcanizing machine includes a frame, the frame including a base, a top plate, and four columns for connecting the base and the top plate;

[0007] A lower support, several middle supports, and an upper support are arranged sequentially from bottom to top between the base and the top plate. Each of the lower, middle, and upper supports has a heating plate mounted on it via a guide structure. Each of the lower, middle, and upper supports has a moving structure for moving the heating plate. The lower support is fixedly mounted on the base. A lifting cylinder is fixedly mounted on the top plate, with its cylinder rod passing through the top plate and fixedly connected to the heating plate on the upper support. An upper template is fixedly mounted on the lower end of the heating plate on the upper support. Lower and upper templates are fixedly mounted on the upper and lower ends of the heating plates on the middle supports, respectively. A lower template is fixedly mounted on the upper end of the heating plate on the lower support. Both sides of the frame are equipped with linkage structures for synchronously moving the lower, middle, and upper supports to achieve synchronous mold opening and closing.

[0008] In this way, by setting up a lower heating plate, several middle heating plates and an upper heating plate, a multi-layer heating structure is formed, which enables multi-layer vulcanization of rubber on a single machine, thereby improving vulcanization efficiency.

[0009] When vulcanizing rubber products, raw materials need to be placed on the lower mold, or the upper or lower mold needs to be replaced. The corresponding moving structure can push the heating plate outwards, improving operational convenience. During vulcanization, all heating plates are vertically aligned, meaning the upper and lower molds are directly opposite each other. The lifting cylinder moves the upper heating plate downwards, and under the action of the linkage structure, the upper mold moves towards the lower mold, achieving synchronous mold closing. After vulcanization, the lifting cylinder moves the upper heating plate upwards, and under the action of the linkage structure, the upper mold moves away from the lower mold, achieving synchronous mold opening.

[0010] Sliding sleeves are fixedly installed at both ends of the middle support and both ends of the upper support, and the sliding sleeves slide in conjunction with the column.

[0011] The guide structure includes guide blocks fixedly installed on both sides of the heating plate, each guide block having a through hole, and guide rods that slide in cooperation with the guide holes of the guide blocks are fixedly installed on both sides of the upper bracket, middle bracket, and lower bracket.

[0012] The movable structure includes a movable hydraulic cylinder fixedly installed on an upper support, a middle support, and a lower support. The cylinder rod of the movable hydraulic cylinder passes through the upper support, the middle support, and the lower support respectively and is fixedly connected to the heating plates corresponding to the upper support, the middle support, and the lower support respectively. The cylinder rod axis is arranged parallel to the axis of the guide rod.

[0013] The linkage structure includes a linkage frame, which consists of two linkage rods hinged in the middle. The linkage frame is located between the lower support and the middle support, between adjacent middle supports, and between the middle support and the upper support. Each of the lower support, middle support, and upper support is equipped with a sliding rod, and each sliding rod has two sliders that are slidably engaged. The two ends of the linkage frame are rotatably connected to two adjacent sliders.

[0014] In summary, this rubber product vulcanizing machine has the advantages of stable structure, simultaneous mold opening and closing, and high efficiency. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0021] like Figure 1-5 As shown, a rubber product vulcanizing machine includes a frame, the frame including a base 1, a top plate and four columns 3 for connecting the base and the top plate;

[0022] A lower support 4, several middle supports 5, and an upper support 6 are arranged sequentially from bottom to top between the base and the top plate. Each of the lower support, middle supports, and upper support has a heating plate 7 mounted on it via a guide structure. Each of the lower support, middle supports, and upper support has a moving structure for moving the heating plate. The lower support is fixedly mounted on the base. A lifting cylinder 8 is fixedly mounted on the top plate, with its cylinder rod passing through the top plate and fixedly connected to the heating plate on the upper support. An upper template 9 is fixedly mounted on the lower end of the heating plate on the upper support. A lower template 10 and an upper template are fixedly mounted on the upper and lower ends of the heating plate on the middle supports, respectively. A lower template is fixedly mounted on the upper end of the heating plate on the lower support. Both sides of the frame are provided with a linkage structure 11 for synchronously moving the lower support, middle supports, and upper support to achieve synchronous mold opening and closing.

[0023] In this way, by setting up a lower heating plate, several middle heating plates and an upper heating plate, a multi-layer heating structure is formed, which enables multi-layer vulcanization of rubber on a single machine, thereby improving vulcanization efficiency.

[0024] When vulcanizing rubber products, raw materials need to be placed on the lower mold, or the upper or lower mold needs to be replaced. The corresponding moving structure can push the heating plate outwards, improving operational convenience. During vulcanization, all heating plates are vertically aligned, meaning the upper and lower molds are directly opposite each other. The lifting cylinder moves the upper heating plate downwards, and under the action of the linkage structure, the upper mold moves towards the lower mold, achieving synchronous mold closing. After vulcanization, the lifting cylinder moves the upper heating plate upwards, and under the action of the linkage structure, the upper mold moves away from the lower mold, achieving synchronous mold opening.

[0025] In practice, sliding sleeves 12 are fixedly installed at both ends of the middle support and both ends of the upper support, and the sliding sleeves slide in engagement with the columns. This facilitates guiding the movement of the middle and upper supports.

[0026] In implementation, the guiding structure includes guide blocks fixedly installed on both sides of the heating plate, each guide block having a through-hole. Guide rods 13, which slide and engage with the guide holes of the guide blocks, are fixedly installed on both sides of the upper, middle, and lower supports. This facilitates guiding the movement of the heating plate and supporting it.

[0027] In implementation, the movable structure includes movable hydraulic cylinders 14 fixedly mounted on the upper, middle, and lower supports. The cylinder rods of the movable hydraulic cylinders pass through the upper, middle, and lower supports respectively and are fixedly connected to the heating plates corresponding to the upper, middle, and lower supports. The axis of the cylinder rod is parallel to the axis of the guide rod. The movable hydraulic cylinders drive the heating plates to move.

[0028] In implementation, the linkage structure includes a linkage frame 15, which is composed of two linkage rods hinged in the middle. The linkage frame is set between the lower support and the middle support, between adjacent middle supports, and between the middle support and the upper support. Each of the lower support, middle support, and upper support is equipped with a sliding rod 16, and each sliding rod has two sliding blocks 17 that are slidably engaged. The two ends of the linkage frame are rotatably connected to the two adjacent sliding blocks.

[0029] Thus, the linkage structure is actually a scissor frame structure. The linkage is achieved through the linkage frame in cooperation with the sliding rod. The structure is simple and easy to use.

[0030] Specifically, it also includes PLC controllers, which are used to control the operation of the electrical components within them.

[0031] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
