Description

A multi-layer flat vulcanizing machine Technical Field

[0001] This utility model relates to the field of rubber vulcanization technology, specifically a multi-layer flat vulcanizing machine. 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 currently only have heating functions. After high-temperature vulcanization, the vulcanizing mold and the internal rubber products require a long time to cool down. Some flat vulcanizing machines use dual-temperature-controlled oil temperature controllers and additional cooling channels inside the flat plate. This allows the coolant circuit of the dual-temperature-controlled oil temperature controller to directly cool the flat plate after heating and vulcanization, thus rapidly cooling the vulcanizing mold. While this improves the cooling efficiency of the mold and rubber products, it also causes the flat plate to drop to a lower temperature, wasting heat. Furthermore, the flat plate needs a longer preheating time before the next vulcanization operation, which needs improvement. Summary of the Invention

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0024] Please refer to Figures 1-4. In this embodiment of the present invention, a multi-layer flat vulcanizing machine includes a frame 1. The top of the frame 1 is fixedly connected to a top plate 3 via four columns 2. A partition 4 is fixedly connected to the middle of the four columns 2. A lower cooling plate 5 is fixedly installed on the top of the partition 4. An upper cooling plate 6 is arranged above the lower cooling plate 5. Cooling liquid channels are provided in both the upper cooling plate 6 and the lower cooling plate 5, and the inlet and outlet of the cooling liquid channels are connected to a chiller via hoses. A first hydraulic cylinder 7 is fixedly installed on the top of the top plate 3. The push rod end of the first hydraulic cylinder 7 is fixedly connected to the upper cooling plate 6. An upper heating plate 9 is fixedly installed at the bottom of the partition 4. A lower heating plate 8 is arranged below the upper heating plate 9. Heat-conducting oil channels are provided in both the upper heating plate 9 and the lower heating plate 8, and the inlet and outlet of the heat-conducting oil channels are connected to an oil temperature controller via hoses. A second hydraulic cylinder 10 is fixedly installed inside the frame 1. The push rod end of the two hydraulic cylinders 10 is fixedly connected to the bottom of the lower heating plate 8. Two third guide grooves 14 and two fourth guide grooves 20 are respectively provided on both sides of the lower heating plate 8 on the frame 1. Multiple fourth hydraulic cylinders 24 are fixedly installed inside the frame 1. The bottom of the third guide groove 14 and the fourth guide groove 20 are fixedly connected to the push rod end of the corresponding fourth guide groove 20. The ends of the two fourth guide grooves 20 away from the lower heating plate 8 are fixedly connected to a third hydraulic cylinder 22. The push rod end of the third hydraulic cylinder 22 is fixedly connected to an electromagnet 23. A lower mold 27 is placed on both the lower heating plate 8 and the lower cooling plate 5. An upper mold 29 is installed on the top of the lower mold 27. An iron block 33 is fixedly connected to the end of the lower mold 27 facing the fourth guide groove 20 through multiple connecting rods 32. Guide bars 28 are fixedly installed on both outer walls of the lower mold 27. The guide bars 28 are adapted to the third guide groove 14 and the fourth guide groove 20.

[0025] By adopting the above-described scheme, in use, when the lower mold 27 is positioned between the two third guide grooves 14 via the two guide bars 28, the upper mold 27 can be moved out to allow material to be placed and removed from the lower mold 27. Afterwards, the upper mold 27 is installed, and the iron block 33 is attracted using the electromagnet 23. Then, the third hydraulic cylinder 22 is activated to move the upper mold 27 and the lower mold 27 onto the lower heating plate 8. The second hydraulic cylinder 10 is then activated to drive the lower heating plate 8 upwards, allowing the two heating plates to clamp the mold and heat it. After heating and vulcanization are completed, the lower heating plate 8 is reset. The mold is then moved between the two fourth guide grooves 20 via the electromagnet 23 and the third hydraulic cylinder 22. The fourth hydraulic cylinder 24 then lifts the fourth guide groove 14 until the mold is above the lower cooling plate 5. Finally, the third hydraulic cylinder... 22 drives the mold to move onto the lower cooling plate 5, which activates the first hydraulic cylinder 7 to drive the upper cooling plate 6 to descend, clamping the mold with the two cooling plates and cooling the mold and rubber product. Then, the fourth hydraulic cylinder 24 drives the third guide groove 14 to move to be flush with the mold, and the third hydraulic cylinder 22 pushes the mold between the two third guide grooves 14. After resetting the height of the two third guide grooves 14, the upper mold 27 can be removed, and the lower mold 27 can be loaded and unloaded again, thus completing one heating vulcanization and cooling shaping process. Since the lower cooling plate 5 and the upper cooling plate 6, as well as the lower heating plate 8 and the upper heating plate 9, can work independently, one set of molds can be heated while another set of molds is cooled, thereby effectively improving the efficiency of vulcanization and reducing heat waste.

[0026] Referring specifically to Figures 1 and 2, in one embodiment of this utility model, two second guide grooves 13 are symmetrically fixedly installed on the top of the lower heating plate 8, and two first guide grooves 12 are symmetrically fixedly installed on the top of the lower cooling plate 5. The first guide grooves 12 and the second guide grooves 13 are located on the same straight line as the corresponding third guide grooves 14 and fourth guide grooves 20 in their top view projection, and both the first guide grooves 12 and the second guide grooves 13 are adapted to the guide strips 28.

[0027] By setting two second guide grooves 13 and a first guide groove 12, the lower mold can be guided on the lower heating plate 8 and the lower cooling plate 5 so as to align the guide bar 28 with the third guide groove 14 and the fourth guide groove 20.

[0028] Referring specifically to Figures 1 and 2, in one embodiment of this utility model, the outer wall of the column 2 is slidably fitted with a sliding sleeve 11 at the corresponding positions of the upper cooling plate 6 and the lower heating plate 8, and the upper cooling plate 6 and the lower heating plate 8 are fixedly connected to the corresponding sliding sleeve 11.

[0029] The sliding sleeve 11, in conjunction with the column 2, guides the movement of the upper cooling plate 6 and the lower heating plate 8, thereby improving their stability during movement.

[0030] Referring specifically to Figure 1, in one embodiment of this utility model, a plurality of guide rods 25 are slidably installed on the top of the frame 1. The bottom of the third guide groove 14 and the fourth guide groove 20 are fixedly connected to the corresponding guide rods 25, so that the guide rods 25 can guide the up and down movement of the third guide groove 14 and the fourth guide groove 20, thereby improving the stability of their movement.

[0031] Referring specifically to Figures 1-4, in one embodiment of this utility model, a fifth hydraulic cylinder 26 is fixedly installed at the bottom of each of the third guide grooves 14, and a support strip 15 is provided above each of the third guide grooves 14. The push rod end of the fifth hydraulic cylinder 26 is fixedly connected to the corresponding support strip 15. Two support grooves 16 are opened at the top of each support strip 15. A first support rod 30 and a second support rod 31 are fixedly connected to the outer walls on both sides of the upper mold 29. The support grooves 16 are adapted to the first support rod 30 and the second support rod 31.

[0032] Furthermore, the top of each of the two third guide grooves 14 is fixedly connected to a vertical plate 17, and the two vertical plates 17 are jointly fixedly connected to a stop bar 18. The outer wall of the stop bar 18 is fitted with a plurality of ball bearings 19, and the two support bars 15 are located between the two vertical plates 17.

[0033] By cooperating with the guide bar 28 and the third guide groove 14, the lower mold 27 is moved between the two third guide grooves 14, and the first support rod 30 and the second support rod 31 are both located directly above the corresponding support groove 16. Then, the fifth hydraulic cylinder 26 is activated to drive the support bar 15 to rise, which in turn drives the upper mold 27 to move upward. When one end of the top of the upper mold 27 contacts the ball bearing 19, the support bar 15 continues to rise, which will cause the upper mold 27 to rotate around the first support rod 30 as the center. Thus, the upper mold 27 is in an inclined state, which makes it easier to pick up and put down materials on the lower mold 27.

[0034] Referring specifically to Figure 4, in one embodiment of this utility model, the top surface of the lower mold 27 is provided with a plurality of positioning holes 35, and the bottom of the upper mold 29 is fixedly installed with positioning pins 34 at the corresponding positions of each positioning hole 35, and the positioning pins 34 are adapted to the positioning holes 35.

[0035] The positioning pin 34 and the positioning hole 35 work together to achieve the positioning and installation between the upper mold 29 and the lower mold 27.

[0036] 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.
