Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically an automatic mold opening device for an upper-pressure vulcanizing machine. Background Technology

[0002] The top-pressure vulcanizing machine is a flat vulcanizing machine, mainly used for the vulcanization and molding of flat products such as flat rubber belts, rubber sheets, and polymers. It belongs to hydraulic machinery, and its main function is to provide the pressure and temperature required for vulcanization. In specific use, after the vulcanizing mold is placed between the processing table and the pressure plate, the hydraulic cylinder is started to drive the pressure plate to move downward to press the vulcanizing mold. Then, the heaters on the pressure plate and the processing table are started to heat the vulcanizing mold.

[0003] Currently, most commonly used top-pressure vulcanizing machines still rely on manual loading and unloading. This requires workers to manually push the mold under the pressure plate. After vulcanization is complete, workers need to pull out the mold and open it to remove the product. This process is time-consuming and labor-intensive. Furthermore, the vulcanizing mold is hot and heavy, resulting in high labor intensity, and needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide an automatic mold opening device for an upper-pressure vulcanizing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic mold-opening device for an upper-pressure vulcanizing machine includes a processing table. A mounting plate is fixedly connected to the top of the processing table via multiple columns. A hydraulic cylinder is fixedly mounted on the top of the mounting plate. A pressure plate is fixedly connected to the push rod end of the hydraulic cylinder. A first electric cylinder is fixedly mounted on the top of the processing table via a fixing plate. A lower mold is detachably connected to the push rod end of the first electric cylinder. A matching upper mold is mounted on the top of the lower mold. First and second positioning rods are fixedly mounted on both outer walls of the upper mold. A support platform is fixedly connected to the outer wall of the processing table away from the first electric cylinder via a support plate. Two second electric cylinders are symmetrically fixedly mounted on the bottom of the support platform. Support rods are fixedly mounted on the push rod ends of the second electric cylinders. The two support rods are located on both sides of the lower mold. A stop bar is fixedly connected to the top of the support platform via two vertical plates.

[0006] As a further embodiment of this utility model: the outer wall of the first positioning rod is fitted with a first bearing, and the outer wall of the stop rod is fitted with a plurality of second bearings.

[0007] As a further embodiment of this utility model: the top of the support rod is provided with a first positioning groove and a second positioning groove, the first positioning groove being adapted to the first bearing, and the second positioning groove being adapted to the second positioning rod.

[0008] As a further embodiment of this utility model: a plurality of positioning pins are fixedly installed on the top of the lower mold, and springs are sleeved on the outer wall of the positioning pins. Stepped positioning holes are opened at the bottom of the upper mold corresponding to each positioning pin, and the stepped positioning holes are adapted to the positioning pins and springs.

[0009] As a further embodiment of this utility model: a connecting strip is fixedly connected to the push rod end of the first electric cylinder, and the connecting strip is detachably connected to the lower mold by multiple bolts. Multiple first guide rods are slidably installed on the outer wall of the fixed plate, and the first guide rods are fixedly connected to the connecting strip.

[0010] As a further embodiment of this utility model: a second guide rod is slidably installed on the top of the support platform and at the corresponding position of each support rod, and the top end of the second guide rod is fixedly connected to the corresponding support rod.

[0011] As a further embodiment of this utility model: the push rod end of the hydraulic cylinder is fixedly connected to a connecting frame, the pressure plate is fixedly installed at the bottom of the connecting frame, and the outer wall of the column is slidably fitted with guide sleeves, all of which are fixedly connected to the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, after vulcanization is completed, the first electric cylinder is activated to push the lower mold onto the support platform. After the first and second positioning rods are positioned directly below the corresponding support rods, the two second electric cylinders are activated to push the two support rods upward simultaneously, thus lifting the upper mold. When the rear top surface of the upper mold contacts the stop rod, the second electric cylinders continue to push the support rods upward, causing the upper mold to rotate around the first positioning rod as the center. This causes the front end of the upper mold to flip upward, increasing the distance between the front end of the upper mold and the lower mold, making it easier for operators to remove the molded product from the lower mold. The operation is simple and convenient, greatly reducing the labor intensity of workers. Attached Figure Description

A pressure plate 7 is fixedly connected to the push rod end of the hydraulic cylinder 4. Electric heaters are installed inside both the pressure plate 7 and the processing table 1. A first electric cylinder 9 is fixedly installed on the top of the processing table 1 via a fixing plate 8. A lower mold 12 is detachably connected to the push rod end of the first electric cylinder 9. The top of the lower mold 12... The upper mold 13 is fitted with a matching upper mold. The upper mold 13 has a first positioning rod 14 and a second positioning rod 16 fixedly installed on both outer walls. The outer wall of the processing table 1 away from the first electric cylinder 9 is fixedly connected to a support plate 20. Two second electric cylinders 25 are symmetrically fixedly installed at the bottom of the support plate 21. The push rod end of the second electric cylinder 25 is fixedly installed with a support rod 26. The two support rods 26 are located on both sides of the lower mold 12. The top of the support plate 21 is fixedly connected to a stop rod 23 through two vertical plates 22.

[0023] By adopting the above-described scheme, this utility model applies pressure to the upper mold 13 by activating the hydraulic cylinder 4 to push the pressure plate 7 downward, thus pressing the upper mold 13 against the surface of the lower mold 12. The mold is then heated. After vulcanization, the pressure plate 7 is reset, and the first electric cylinder 9 is activated to push the lower mold 12 onto the support platform 21. Once the first positioning rod 14 and the second positioning rod 16 are directly below the corresponding support rod 26, the two second electric cylinders 25 are activated to push the two support rods 26 upward simultaneously, lifting the upper mold 13. When the rear end of the upper mold contacts the stop rod 23, the second electric cylinders 25 continue to push the support rods 26 upward, causing the upper mold 13 to rotate around the first positioning rod 14. This causes the front end of the upper mold 13 to flip upward, increasing the distance between the front end of the upper mold 13 and the lower mold 12, making it easier for operators to remove the molded product from the lower mold 12. The operation is simple and convenient, greatly reducing the labor intensity of workers.
