Description

Technical Field

[0001] The utility model relates to the technical field of vulcanizing machines, in particular to an ejection device of a large-scale full-automatic vulcanizing machine. Background Art

[0002] Vulcanization, also known as cross-linking or aging, is the process of adding cross-linking agents such as vulcanizers and accelerators to rubber to transform linear macromolecules into three-dimensional network structures under certain temperature and pressure conditions. Since sulfur was first used to achieve cross-linking of natural rubber, it is called vulcanization. A vulcanizer is a machine that vulcanizes various rubber and plastic products. It has functions such as timed mold locking, automatic pressure replenishment, automatic temperature control, automatic timing, and time alarm. The vulcanizer is divided into three types: electric heating, steam heating, and thermal oil heating.

[0003] At present, vulcanizing machines are needed in the production of vulcanized products. Generally, vulcanized products will adhere tightly to the mold cavity of the mold. Although an ejection device is provided, forced ejection will cause the outer wall of the vulcanized product to tear and break, resulting in poor product quality and increased costs. In order to avoid this situation, the ejection device is improved. Therefore, an ejection device for a large-scale fully automatic vulcanizer is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3The ejection device of a large-scale fully automatic vulcanizer includes a mold body 1, a support frame 2 is installed at the bottom of the mold body 1, a mounting frame 3 is arranged above the support frame 2, a screw 11 is arranged between the mounting frame 3 and the mold body 1, and a driving motor 4 connected to the screw 11 is arranged on the support frame 2. An ejection plate 19 is arranged inside the mold body 1 through a receiving groove, an ejection frame 5 connected to the ejection plate 19 is slidably penetrated through the mold body 1 through a first elastic mechanism, a lifting frame 12 is threadedly sleeved on the screw 11, a driving gear 16 and an incomplete gear 17 are arranged on the support frame 2 through a fixed frame 15, and the driving gear 16 is connected to the lifting frame 12 through a rotating mechanism, a slide bar 8 is installed on the mold body 1, and an impact frame 7 is slidably sleeved on the slide bar 8 through a second elastic mechanism, and the incomplete gear 17 is connected to the impact frame 7 through a transmission mechanism.

[0021] The first elastic mechanism includes a vertical spring 6 sleeved on the ejector frame 5, and the two ends of the vertical spring 6 are elastically connected to the bottom wall of the mold body 1 and the outer wall of the ejector frame 5 respectively. The vertical spring 6 realizes the descending and resetting of the ejector frame 5, thereby ensuring that the upper end surface of the ejector plate 19 is flush with the inner bottom wall of the mold body 1.

[0022] The rotating mechanism includes an active rack 14 installed on the lifting frame 12, and the active rack 14 is meshed with the active gear 16. The lifting frame 12 can drive the active gear 16 to rotate forward and reverse. In this solution, the impact frame 7 and the impact block 10 are at a certain distance from the outer wall of the mold body 1. Even if the lifting frame 12 descends, the impact block 10 is driven by multiple components to move closer to the mold body 1 without causing any impact.

[0023] The second elastic mechanism includes a transverse spring 9 which is sleeved on the outside of the slide rod 8. The two ends of the transverse spring 9 are elastically connected to the outer wall of the impact frame 7 and the outer wall of the mold body 1 respectively. After being stretched, the transverse spring 9 can restore to drive the impact frame 7 to move in the opposite direction and cooperate with the impact block 10 to realize the impact on the mold body 1.

[0024] The transmission mechanism includes a transmission rack 18 installed on the impact frame 7, and the transmission rack 18 cooperates with the incomplete gear 17. When the part without teeth on the incomplete gear 17 corresponds to the transmission rack 18, the impact frame 7 will lose the meshing force restraint.

[0025] A limit rod 13 is provided between the mounting frame 3 and the mold body 1 . The limit rod 13 is parallel to the screw rod 11 and slides through the lifting frame 12 . The limit rod 13 limits the lifting frame 12 and effectively prevents it from rotating with the screw rod 11 .

[0026] When the utility model is used, when the production is completed and the ejection operation needs to be performed, the driving motor 4 is started to drive the screw 11 to rotate. When the screw 11 rotates, the lifting frame 12 threadedly mounted thereon will rise. The lifting frame 12 first drives the driving gear 16 and the incomplete gear 17 to rotate synchronously with the help of the active rack 14. The rotation of the incomplete gear 17 drives the impact block 10 to move on the slide bar 8 and away from the mold body 1 with the help of the transmission rack 18. After the part without teeth on the incomplete gear 17 corresponds to the transmission rack 18, the impact frame 7 loses its restriction and driven by the recovery trend of the transverse spring 9, the impact block 10 hits the mold body 1 to generate vibration, thereby facilitating the outer wall of the molded product to separate from the inner wall of the mold body 1. Subsequently, the lifting frame 12 contacts the ejection frame 5, and drives the ejection plate 19 to rise during the subsequent rising process, thereby realizing the convenient ejection operation of the molded product in the mold body 1.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
