Description

Technical Field

[0001] The utility model relates to the technical field of vulcanization molds, and particularly to a multi - ejection structure for mold demolding of a vulcanizer. Background Technique

[0002] A vulcanizer is a machine for vulcanizing various rubber and plastic products, with functions such as timing mold clamping, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. Vulcanizers are divided into three forms: electric heating, steam heating, and heat - conducting oil heating. There is a forming mold mechanism in the vulcanizer, which can perform forming operations on rubber.

[0003] During the use of existing forming molds, it is often necessary to heat the rubber placed in the mold to soften it, and then perform pressing for a certain period of time to form the rubber. However, after the product is vulcanized, the middle template is taken out from the forming mold. When the product is vulcanized, the upper template needs to seal the middle template. When the upper template seals the middle template, it may cause a certain extrusion to the middle template, making it more laborious for the staff to take out the middle template, resulting in a high labor intensity for the staff. Therefore, this application proposes a multi - ejection structure for mold demolding of a vulcanizer to solve the above - mentioned technical problems. Content of the Utility Model

[0039] In this embodiment, a multi - ejection structure for mold demolding of a vulcanizer of the present invention is given. By placing the product to be vulcanized in the middle template 2, and then sealing the middle template 2 with the upper template 4. At the same time, when the upper template 4 seals the middle template 2, it will squeeze the driving rods 54, so that the driving rods 54 drive the moving plate 53 to move. When the product is vulcanized, the upper template 4 is reset, and then the demolding assembly 5 will eject the middle template 2 from the lower template 1, thereby improving the demolding efficiency.

[0040] Furthermore, limit blocks are arranged on the upper surfaces of at least two guide posts 3 for limiting the upper template 4.

[0041] Further, as Figure 2 shown, the lower template 1 in the preferred embodiment of the present invention further includes four relief holes 11, evenly distributed on the upper surface of the lower template 1, and the four driving rods 54 are respectively located in the four relief holes 11; an installation groove 12, opened on the upper surface of the lower template 1 for placing the middle template 2; and two sliding holes 13, symmetrically opened on the inside of the installation groove 12.

[0042] In this embodiment, a plurality of preferred embodiments of the lower template 1 are provided. The upper template 4 can squeeze the driving rod 54 in the clearance hole 11 when sealing the middle template 2 through the clearance hole 11, and the middle template 2 can be limited through the mounting groove 12, thereby ensuring the stability of the middle template 2 when vulcanizing the product.

[0043] Further, such as Figures 3 to 4 As shown, the demolding assembly 5 in the preferred embodiment of the utility model also includes a limit member 55, which is detachably arranged on the inner side of the base plate 52; two guide rods 56, which are symmetrically arranged on the lower surface of the lower mold plate 1; two demolding rods 57, which are symmetrically arranged on the upper surface of the movable plate 53, and the two demolding rods 57 are respectively located in the two sliding holes 13; two return springs 58, which are respectively sleeved on the outer sides of the two guide rods 56; a limit groove 59, which is opened on the lower surface of the base plate 52; and a fixing hole 510, which is opened on the inner side of the limit groove 59.

[0044] Furthermore, the two guide rods 56 both penetrate the movable plate 53 , and the lower end surfaces of the two guide rods 56 both contact the limiting member 55 .

[0045] Furthermore, the limiting member 55 includes a limiting plate 551, which is arranged in the limiting groove 59, and the limiting plate 551 is set on the inner side of the limiting groove 59 by bolts; the mounting block 552 is arranged on the upper surface of the limiting plate 551, and the mounting block 552 is located on the inner side of the fixing hole 510 and contacts the lower end surfaces of the two guide rods 56.

[0046] Furthermore, the upper and lower end surfaces of the return spring 58 are in contact with the moving plate 53 and the mounting block 552 respectively.

[0047] Furthermore, when the upper end surface of the driving rod 54 is flush with the upper surface of the lower mold plate 1 , the upper end surface of the demoulding rod 57 is flush with the inner side of the mounting groove 12 .

[0048] In this embodiment, multiple preferred embodiments of the demolding assembly 5 are given. When the upper template 4 seals the middle template 2, when the lower surface of the upper template 4 contacts the upper surface of the driving rod 54, the driving rod 54 will be extruded, so that the upper surface of the driving rod 54 is flush with the upper surface of the lower template 1. Then the driving rod 54 will drive the moving plate 53 to move, and the moving plate 53 will drive the demolding rod 57 to move and extrude the return spring 58. When the product vulcanization is completed and the upper template 4 is reset, under the action of the rebounding force of the return spring 58, the return spring 58 will reset the moving plate 53, so that the moving plate 53 drives the demolding rod 57 to reset, and further the demolding rod 57 ejects the middle template 2 in the installation groove 12. At the same time, the limiting member 55 can be removed from the limiting groove 59, so as to replace the return spring 58, and further ensure the reset effect of the return spring 58 on the moving plate 53.

[0049] The posture of the demolding assembly 5 in the attached drawings of the specification of this application is the posture after being extruded by the upper template 4.
