Abstract
Description
Technical Field
[0001] This utility model relates to a sliding core mold suitable for rubber molding, belonging to the field of mold technology. Background Technology
[0002] A vulcanizing machine combines mechanical pressure and temperature control with the physical structure of the mold to cause a vulcanization reaction in rubber under high temperature and pressure, thereby forming a rubber product of the desired shape. While existing molds have simple structures and relatively straightforward operation, the production process still requires repeated manual removal and installation of the sliders. This manual operation is time-consuming and labor-intensive, and can easily lead to incorrect core orientation, resulting in product rejection and mold damage. Furthermore, the sliders are prone to sticking when the vulcanizing equipment opens and closes the mold, causing them to detach from the mold, which can damage the mold or even injure personnel. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model proposes a sliding core mold suitable for rubber molding, which aims to facilitate the removal of rubber products without the need to disassemble the slider.
[0004] The technical solution adopted in this utility model is a sliding core mold suitable for rubber molding, including an upper template, a lower template, a cover plate, a push plate, and a slider. One side surface of the push plate is an L-shaped end face. Several sliders are placed in the cavity in sequence. The two sides of the slider are located inside the L-shaped end face, and there is a gap between one side of the slider and the side of the L-shaped end face. The cover plate is fixed to the push plate by screws. The cover plate and the push plate cooperate to fix the slider. The upper template and the lower template are opened and closed by positioning guide posts and positioning guide sleeves.
[0005] Furthermore, a pin hole is provided on the L-shaped end face, and the other side of the slider is fixed to the push plate by a positioning pin.
[0006] Furthermore, a fixing plate is provided below the push plate, and the push plate and the fixing plate are connected by bolts.
[0007] Furthermore, the upper template is fixed to the upper heating plate of the vulcanizing machine, and the lower template is fixed to the lower heating plate of the vulcanizing machine.
[0008] Furthermore, the lower surface of the pusher plate contacts the oil cylinder of the vulcanizing machine.
[0009] Furthermore, the gap distance is sufficient to allow the rubber product to be removed when the slider moves to the side wall of the L-shaped end face.
[0010] This utility model discloses a sliding core mold suitable for rubber molding. Its advantages are as follows: compared with existing technologies, the upper and lower mold plates are precisely positioned by positioning guide pillars and positioning guide sleeves, ensuring smooth operation during mold opening and closing. The L-shaped end face on the push plate is fixed to the cover plate with screws, forming a stable frame structure for fixing the slider in the vertical direction. A gap is reserved between the L-shaped end face and the eighth slider to facilitate the removal of the rubber product. The pin hole on the L-shaped end face is used to fix the first slider, ensuring safe and reliable assembly. When the rubber product needs to be removed, the operator only needs to move the slider horizontally, exposing the cavity between adjacent sliders, and remove the rubber product from the cavity. The process does not require manual removal of the sliders, significantly reducing manual operation time, improving production efficiency, and reducing the product scrap rate and mold damage risk caused by improper manual operation. It also avoids personnel injury caused by improper equipment operation. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] To further understand the content of this utility model, the technical solution will be further described below in conjunction with specific embodiments.
[0019] Example 1: As Figures 1-4 As shown, this embodiment provides a sliding core mold suitable for rubber molding. In this embodiment, there are 8 sliders 3, including an upper template 1, a lower template 2, a cover plate 6, a push plate 4, and sliders 3. One side surface of the push plate 4 is an L-shaped end face 11, which consists of a vertical surface and a horizontal surface. The lower surface of the horizontal surface is flush with the lower surface of the push plate 4. The 8 sliders 3 are placed side by side in the cavity. For the convenience of those skilled in the art to understand this technical solution, they are sequentially defined as the first slider 3 to the eighth slider 3. The two sides of the slider 3 are located inside the L-shaped end face 11, and there is a gap 12 between one side of the slider 3 and the side of the L-shaped end face 11. Specifically, the first slider 3 and the eighth slider 3 overlap on the L-shaped end face, with the first slider 3 in close contact with the vertical surface of the L-shaped end face 11, and a gap 12 is reserved between the eighth slider 3 and the vertical surface of the L-shaped end face 11. The width of the gap 12 is sufficient for the eighth slider 3 to move to the side wall of the L-shaped end face 11 to remove the rubber product. To ensure accurate and convenient removal of the finished rubber product, a gap 12 is reserved between the eighth slider 3 and the vertical surface of the L-shaped end face, allowing for a travel distance for the horizontal movement of the slider 3.
[0020] In a specific embodiment of this invention, the cover plate 6 is fixed above the push plate 4 by screws 7. The cover plate 6 and the L-shaped end face 11 of the push plate 4 cooperate to fix the slider 3 in the vertical direction. The upper template 1 and the lower template 2 are opened and closed by positioning guide posts 9 and positioning guide sleeves. Specifically, the upper template 1 is fixed on the upper heating plate of the vulcanizing machine, and the lower surface of the upper template 1 is provided with positioning guide posts 9. The lower template 2 is fixed on the lower heating plate of the vulcanizing machine, and the upper surface of the lower template 2 is provided with positioning guide sleeves. The positioning guide posts 9 and positioning guide sleeves are in sliding clearance fit. The lower surface of the push plate 4 is in contact with the hydraulic cylinder of the vulcanizing machine. When the mold needs to be opened, the vulcanizing machine drives the upper template 1 and the lower template 2 to separate. The hydraulic cylinder lifts the push plate 4, and the operator moves the slider 3 horizontally, that is, moves the eighth slider 3 in the direction of the gap 12. This process is repeated between adjacent sliders 3 to expose the rubber product in the cavity, thereby allowing the rubber product to be removed without removing the slider 3.
[0021] Example 2: As Figures 1-4 As shown, based on Embodiment 1, the L-shaped end face 11 in this embodiment is provided with a pin hole for inserting a positioning pin 10, and the first slider 3 and the push plate 4 are fixed together by the positioning pin 10. A fixing plate 5 is provided below the push plate 4, and the push plate 4 and the fixing plate 5 are connected by bolts 8.
[0022] In practical application, taking Embodiment 2 as an example, as follows: Figures 1-4 As shown, the upper mold plate 1 and lower mold plate 2 open under the drive of the vulcanizing machine. The hydraulic cylinder then lifts the push plate 4, and the fixing plate 5 rises with the push plate 4. The first slider 3 is fixed to the push plate 4 by the positioning pin 10. At this time, the operator only needs to manually move the eighth slider 3 towards the direction of the gap 12, and then move the other sliders 3 towards the direction of the eighth slider 3, so that the rubber product in the cavity is exposed and the rubber product can be removed. Then, each slider 3 is moved towards the direction of the first slider 3, so that the adjacent sliders 3 fit tightly together. At this time, the upper mold plate 1 and lower mold plate 2 close under the drive of the vulcanizing machine, and the next vulcanization continues.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
