Description

Technical Field

[0001] This utility model relates to the technical field of vulcanizing equipment, and in particular to a mold opening structure that is not prone to sticking to the mold. Background Technology

[0002] A vulcanizing machine is a machine used to vulcanize various rubber and plastic products. It features functions such as timed mold locking, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. Vulcanizing machines are available in three types: electric heating, steam heating, and heat transfer oil heating. They are also known as flat vulcanizing machines, foam board vulcanizing machines, and rubber vulcanizing machines.

[0003] Currently, vulcanizing machines are generally equipped with molds, including upper and lower molds. Sometimes, a middle plate is also placed between the upper and lower molds. When vulcanizing rubber products, the rubber is placed between the upper and lower molds. After vulcanization, the mold is opened to remove the product. However, currently, the middle plate is prone to sticking to the upper mold when opening the mold. When the upper mold rises during mold opening, forcibly pulling down the middle plate can easily cause the middle plate to fall and damage the mold and the product. Utility Model Content

[0004] To prevent the middle plate from sticking to the upper mold during mold opening, this utility model provides a mold opening structure that is less prone to sticking, addressing the problems of existing technologies.

[0005] This utility model provides a mold opening structure that is less prone to sticking, and adopts the following technical solution:

[0006] A mold opening structure that is less prone to sticking includes two secondary support plates, two primary support plates, a middle plate disposed between the two secondary support plates, and an upper mold disposed between the two primary support plates. The upper mold is located above the middle plate and is supported on the primary support plates. The middle plate is supported on the secondary support plates. A limiting shaft is provided on the secondary support plates, and a driving component is provided on the secondary support plates to drive the limiting shaft closer to or further away from the middle plate. The driving component drives the limiting shaft to move along the movement path of the middle plate.

[0007] Preferably, the driving component includes a driving cylinder disposed on the second-layer support plate, and the piston rod of the driving cylinder is fixedly connected to the limiting shaft.

[0008] Preferably, the upper mold has a clearance groove on its side facing the limiting shaft.

[0009] Preferably, the second-layer support template is provided with a guide block, and the limiting shaft movably passes through the guide block.

[0010] Preferably, the two-layer support template is provided with steps on the side facing the middle plate, and the middle plate is provided with protruding edges on opposite sides. The protruding edges support the steps, and the side of the protruding edges abuts against the side wall of the steps.

[0011] Preferably, the first-layer support template is arranged in a U-shape, the second-layer support template is provided with a receiving groove, and the first-layer support template is embedded in the receiving groove.

[0012] Preferably, the upper mold has a supporting column on its side near the first layer support template, and the first layer support template has a limiting groove, with the supporting column supported on the limiting groove.

[0013] In summary, the present invention includes at least one of the following beneficial technical effects of a mold opening structure that prevents mold sticking:

[0014] When the mold opens, the piston rod of the drive cylinder extends, driving the limiting shaft to move directly above the middle plate. Meanwhile, a support platen lifts the upper mold upwards, while the middle plate is held in place by the limiting shaft. This separates the upper mold from the middle plate, preventing the middle plate from sticking to the upper mold during mold opening. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and 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 a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] This utility model discloses a mold opening structure that is not prone to sticking, such as... Figure 1-4 As shown, the system includes two second-layer support templates 1, two first-layer support templates 2, a middle plate 3 disposed between the two second-layer support templates 1, and an upper mold 4 disposed between the two first-layer support templates 2. The upper mold 4 is located above the middle plate 3. During vulcanization, the lower surface of the upper mold 4 is in contact with the upper surface of the middle plate 3. The second-layer support templates 1 are provided with steps 14 on their sides facing the middle plate 3. The middle plate 3 is integrally formed with protruding edges 31 on both sides near the two second-layer support templates 1. The protruding edges 31 are supported on the steps 14, and the sides of the protruding edges 31 abut against the side walls of the steps 14. This allows the second-layer support templates 1 to support the middle plate 3 and limit the middle plate 3, making it less likely for the middle plate 3 to shift.

[0023] In addition, two support columns 42 are fixedly installed on both sides of the upper mold 4 near the two first-layer support templates 2. A limiting groove 21 is opened on the upper surface of the first-layer support template 2, and the support columns 42 are supported on the limiting groove 21. This allows the first-layer support template 2 to support the upper mold 4 and at the same time limit the upper mold 4, making it less likely to shift. In addition, the first-layer support template 2 is arranged in a U-shape, and the second-layer support template 1 has a receiving groove 15. The first-layer support template 2 is embedded in the receiving groove 15, which makes the structure between the one-side support template and the second-layer support template more compact and improves the space utilization rate.

[0024] In addition, a limiting shaft 11 is provided on the second-layer support template 1. A driving component is provided on the second-layer support template 1 to drive the limiting shaft 11 closer to or further away from the middle plate 3. Specifically, the driving component includes a driving cylinder 12 fixedly installed on the second-layer support template 1. The piston rod of the driving cylinder 12 is fixedly connected to the limiting shaft 11. When the piston rod of the driving cylinder 12 extends, the end of the limiting shaft 11 near the middle plate 3 moves to directly above the middle plate 3. Thus, when the mold is opened, the first-layer support template 2 drives the upper mold 4 to rise, while the middle plate 3 is limited by the limiting shaft 11, thereby separating the upper mold 4 from the middle plate 3. In addition, a guide block 13 is fixedly installed on the second-layer support template 1. The limiting shaft 11 moves through the guide block 13. The guide block 13 can improve the structural strength of the limiting shaft 11, making it less likely for the piston rod of the driving cylinder 12 to be bent between the limiting shaft 11 and the limiting shaft 11. In addition, the upper mold 4 has a relief groove 41 on the side facing the limiting shaft 11. When one end of the limiting shaft 11 moves to the top of the middle plate 3, the end of the limiting shaft 11 is located in the relief groove 41. When the area of ​​the upper mold 4 is large and the side of the upper mold 4 is flush with the side of the middle plate 3, the relief groove 41 can make the limiting shaft 11 successfully limit the middle plate 3 without affecting the upper mold 4.

[0025] The implementation principle of the mold opening structure that is not easy to stick to the mold in this embodiment of the utility model is as follows: When the mold is opened, the piston rod of the driving cylinder 12 extends and drives the limiting shaft 11 to move directly above the middle plate 3. The first layer of the support plate 2 drives the upper mold 4 to rise, while the middle plate 3 is limited by the limiting shaft 11, so that the upper mold 4 and the middle plate 3 are separated, preventing the middle plate 3 from sticking to the upper mold 4 when the mold is opened.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
