Description

Technical Field

[0001] This utility model relates to the field of rubber vulcanization technology, specifically a vulcanizing machine mold changing device. Background Technology

[0002] A flat vulcanizing machine is a commonly used rubber vulcanizing equipment. Its main function is to provide the pressure and temperature required for vulcanization. The pressure is generated by a hydraulic system through hydraulic cylinders, and the temperature is provided by a heating medium (usually steam, heat transfer oil, etc., and superheated water is also used).

[0003] Most commonly used flat vulcanizing machines are used with only one set of molds. Although some flat vulcanizing machines have a mold pushing function, which can push the mold out from between the heating plates and open the mold after vulcanization is completed, so as to facilitate the workers to pick up and put down the material on the mold, the time for picking up and putting down the material is long, which will affect the production efficiency. Therefore, we propose a vulcanizing machine mold changing device. Utility Model Content

[0004] The purpose of this invention is to provide a vulcanizing machine mold changing device to solve the problems mentioned in the background art.

[0022] Please see Figures 1-3 In this embodiment of the present invention, a vulcanizing machine mold changing device includes a base 1. A support plate 3 is fixedly connected to the top of the base 1 via multiple columns 2. A turntable 6 is rotatably mounted inside the support plate 3. A reduction stepper motor 5 is fixedly mounted to the top of the base 1 via a frame 4. The output shaft of the reduction stepper motor 5 is fixedly connected to the bottom of the turntable 6. Two workstations are centrally symmetrically arranged on the top of the turntable 6. Two first guide grooves 9 are fixedly installed on the top of the turntable 6 corresponding to each workstation. A groove is provided between each of the two first guide grooves 9. The lower mold 18 has two guide bars 20 symmetrically fixedly installed on its two outer walls. The guide bars 20 are located in the corresponding first guide grooves 9. The top of the lower mold 18 is fitted with an upper mold 19. The top of the support plate 3 has two second guide grooves 28 fixedly installed. The second guide grooves 28 are adapted to the guide bars 20. The top of the support plate 3 is fixedly installed with a multi-stage hydraulic cylinder 16. The push rod end of the multi-stage hydraulic cylinder 16 is fixedly connected to an electromagnet 17. One end of the outer wall of the upper mold 19 is fixedly connected to an iron block 26 through multiple connecting rods 25.

[0023] This utility model, by adopting the above-described scheme, installs the base 1 on one side of the flat vulcanizing machine so that the second guide groove 28 is close to and aligned with the lower heating plate of the flat vulcanizing machine. During use, the stepper controller drives the reduction stepper motor 5 to rotate the turntable 6 until the first guide groove 9 at one station is aligned with the second guide groove 28. Then, the multi-stage hydraulic cylinder 16 is activated, pushing the lower mold 18 and upper mold 19 into the flat vulcanizing machine via the second guide groove 28. The molds can then be heated and vulcanized. During this process, materials can be loaded and unloaded from the molds at another station. After the plate vulcanizing machine completes the vulcanization operation, the multi-stage hydraulic cylinder 16 is restarted, and the iron block 26 is attracted by the electromagnet 17, which can drag the mold in the plate vulcanizing machine back to the station on the turntable 6. Then, the electromagnet 17 is turned off and the multi-stage hydraulic cylinder 16 is reset, and the turntable 6 is driven to rotate 180°, so that the first guide groove 9 of the other station is aligned with the second guide groove 28 on the pallet 3. Then, the multi-stage hydraulic cylinder is started, which can push the mold on the station into the plate vulcanizing machine for vulcanization, so that the two sets of molds can be used in a cycle, thereby effectively improving the production efficiency of vulcanization processing.

[0024] Specific combination Figure 1-3 In one embodiment of this utility model, a first support rod 23 and a second support rod 24 are fixedly installed on both outer walls of the upper mold 19. A support strip 11 is provided above the first guide groove 9. The top of the support strip 11 and the corresponding position of the first support rod 23 and the second support rod 24 are provided with a support groove 12. A first hydraulic cylinder 10 is fixedly installed at the bottom of the turntable 6 and the corresponding position of each support strip 11. The bottom of the support strip 11 is fixedly connected to the push rod end of the corresponding first hydraulic cylinder 10.

[0025] Furthermore, two vertical plates 13 are fixedly connected to the top of the turntable 6 at the corresponding position of each workstation. The first guide groove 9 is located between the two corresponding vertical plates 13. A stop bar 14 is fixedly connected to both vertical plates 13. A plurality of ball bearings 15 are sleeved on the outer wall of the stop bar 14.

[0026] When the first support rod 23 and the second support rod 24 are directly above the corresponding support groove 12, the first hydraulic cylinder 10 is activated to push the support bar 11 upward, which can lift the upper mold 19 to open the mold. After the top of the upper mold 19 is released from the ball bearing 15, the support bar 11 continues to move upward, which can make the upper mold 19 rotate around the first support rod 23 as the center, thereby increasing the distance between the upper mold 19 and the lower mold 18, making it easier to pick up and put down materials.

[0027] Specific combination Figure 1 In one embodiment of this utility model, a stop block 27 is fixedly installed on the top of the turntable 6 at the corresponding position of each workstation.

[0028] By setting the stop block 27, when the mold is pulled back from the flat vulcanizing machine to the turntable 6 using the electromagnet 17 and the multi-stage hydraulic cylinder 16, the stop block 27 can be used to position the lower mold 18 on the turntable 6, thereby facilitating the alignment of the first support rod 23 and the second support rod 24 with the corresponding support groove 12 in the vertical direction.

[0029] Specific combination Figure 3 In one embodiment of the present invention, the top of the lower mold 18 is provided with a plurality of positioning holes 22, and the bottom of the upper mold 19 is fixedly installed with positioning pins 21 at the corresponding positions of each positioning hole 22, and the positioning pins 21 are adapted to the positioning holes 22.

[0030] The positioning pin 21 and the positioning hole 22 make it easy to position and install the upper mold 19 on the lower mold 18.

[0031] A support ring 7 is fixedly installed at the bottom of the support plate 3, and multiple balls 8 are rotatably embedded in the support ring 7.

[0032] The support ring 7 and the ball bearing 8 are arranged to support the bottom of the turntable 6 and ensure the stability of the turntable 6 rotation.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
