Description

Technical Field

[0001] The present invention relates to the technical field of demoulding devices, and in particular to an intelligent demoulding device for a rubber shock-absorbing pad forming mold. Background Art

[0002] Rubber shock-absorbing pads are a type of shock-absorbing device that uses the elasticity and damping properties of rubber to absorb and disperse vibration energy. They are widely used in automobiles, construction, machinery, home appliances and other fields to reduce vibration and noise and improve the stability and service life of equipment.

[0003] Under existing technology, the process of producing rubber shock-absorbing pads is as follows: first, the rubber is accurately weighed, and then the weighed rubber is cut into a suitable shape. Next, the release agent is evenly sprayed on the inside of the mold. The middle mold is then placed stably on the lower mold, and a certain amount of rubber is accurately placed inside the middle mold. The closed mold is automatically pushed into the flat vulcanizer. The upper mold is precisely aligned with the middle mold and moves downward, pressing the middle mold so that the rubber is firmly pressed under the upper mold, thereby starting the vulcanization production process. After vulcanization is completed, the upper mold automatically moves upward and separates from the middle mold. After that, the vulcanizer pushes out the lower mold and the middle mold as a whole. However, during the production process of rubber shock-absorbing pads, excess rubber will form rubber sheets in the gap between the upper mold and the middle mold, resulting in multiple rubber shock-absorbing pads connected to each other, and the rubber shock-absorbing pads will adhere to the middle mold due to the excess rubber sheets. At this time, the staff needs to use an iron rod to pry apart the middle mold and the lower mold. Finally, the produced rubber shock-absorbing pad needs to be manually separated from the removed middle mold by the staff and trimmed, thus completing the entire production process of the rubber shock-absorbing pad.

[0004] During the production process of rubber shock-absorbing pads, the vulcanization process requires applying a certain pressure and temperature, and the rubber itself has adhesiveness. When the upper mold and the middle mold are closed, the molds are tightly fitted together, making it difficult to demold the rubber. The workers need to expend a lot of effort to complete the separation. The workers need to use an iron rod to pry apart the middle mold and the lower mold, and then they need to manually separate the produced rubber shock-absorbing pads, which increases the labor intensity of the workers and reduces the production efficiency of the product.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example 1

[0037] Reference Figure 3 and Figure 4, which is the first embodiment of the present invention, provides an intelligent demolding device for a rubber shock-absorbing pad molding mold. A servo motor 15 is provided inside the vulcanization base 12. A lower template 31 is movably provided on the top of the vulcanization base 12. A transmission structure 34 that engages with the top of the transmission guide rail 2 is fixedly provided on one side of the lower template 31. A transmission guide rail 2 is fixedly provided on the top of the vulcanization base 12. An ejection guide rail 4 corresponding to the transmission guide rail 2 is fixedly provided on the top of the vulcanization base 12. The transmission guide rail 2 and the ejection guide rail 4 serve as guide rails on the vulcanization base 12, so that the lower template 31 can be moved in a directional manner above it. At the same time, moving the lower template 31 will drive the transmission structure 34 on one side of it to slide on the transmission guide rail 2.

[0038] Reference Figure 8 A rotating handle 36 is fixed on the other side of the lower template 31. The rotating handle 36 relies on the weight of the lower template 31 and its internal equipment to make the inner bottom of the rotating handle 36 engage with the ejection guide rail 4. When the servo motor 15 drives the ejection guide rail 4 to move, the ejection guide rail 4 drives the rotating handle 36 engaged with it to move, thereby driving the lower template 31 to be pushed outward.

[0039] Reference Figure 6 and Figure 7 A lifting mechanism 35 is engaged with one end of the transmission structure 34, and a lower mold 32 located inside the lower template 31 is provided on the top of the lifting mechanism 35. When the servo motor 15 drives the ejection guide rail 4 to move the lower template 31 upward, the transmission structure 34 moves on the top of the transmission guide rail 2, thereby driving the lifting mechanism 35 engaged with the transmission structure 34 to rotate, and then the lifting mechanism 35 rotates to move the lower mold 32 at one end thereof upward, automatically ejecting the product in the lower template 31 to achieve demolding.

[0040] Cleaning grooves 33 are evenly formed on the top of the lower template 31 , and the overflowed rubber raw material is guided through the cleaning grooves 33 , thereby facilitating cleaning by the staff.

[0041] Compared with the prior art, in the present embodiment, during the process of demolding the mold, the servo motor 15 drives the ejection guide rail 4 to move the rotating handle 36 above it. At this time, the rotating handle 36 drives the lower template 31 to slide on the transmission guide rail 2 and the ejection guide rail 4, so that the transmission structure 34 on one side of the lower template 31 slides relative to the transmission guide rail 2, so that the transmission structure 34 drives the lifting mechanism 35 engaged with it to rotate, and the lifting mechanism 35 controls the lower mold 32 at one end thereof to move upward, thereby automatically demolding and ejecting the product.

[0042] At the same time, when the lower template 31 moves outward to a set distance, the rotating handle 36 can be held to rotate the transmission structure 34 on one side of the lower template 31 around the transmission guide rail 2 and form a certain angle with the horizontal plane, thereby facilitating the staff to clean and collect the rubber products and excess rubber sheets automatically ejected from the surface of the lower template 31, thereby increasing the comfort of the staff.

[0043] Specifically, first, the servo motor 15 starts working and drives the ejection guide rail 4 to start rotating, and then the ejection guide rail 4 drives the rotating handle 36 above it and engaged with the ejection guide rail 4 to move together, so that the rotating handle 36 drives the lower template 31 to move outward and eject, and then the lower template 31 drives the transmission structure 34 on the other side to slide on the transmission guide rail 2. Due to the relative sliding between the transmission structure 34 and the transmission guide rail 2, the transmission structure 34 will drive the lifting mechanism 35 at one end to start rotating, and then the lifting mechanism 35 pushes the top plate 38 along the inner wall of the lower mold cavity 321 to The lower mold 31 is moved upward until the top plate 38 pushes the rubber product out of the lower mold cavity 321, thereby automatically demolding the rubber product in the lower mold 32 during the process of the lower mold 31 being automatically pushed outward. When the lower mold 31 moves outward to a set distance, the staff can hold the rotating handle 36 and lift it upward to make the multiple transmission structures 34 on the other side of the lower mold 31 start to rotate around the transmission guide rail 2, so that the lower mold 31 starts to tilt and present a certain angle with the horizontal plane. At this time, the staff can collect and clean the rubber product and excess rubber sheets on the surface of the lower mold 31.

[0044] Example 2

[0045] Reference Figure 6 , which is a second embodiment of the present invention, provides an intelligent demolding device for a rubber shock-absorbing pad molding mold. The transmission structure 34 includes a connecting handle 341 fixedly arranged on one side of the lower template 31. A transmission gear 1 342 is movably provided inside the connecting handle 341. A transmission rod 343 is fixedly provided at one end of the transmission gear 1 342. A transmission bevel gear 344 is fixedly provided at one end of the transmission rod 343. The transmission bevel gear 344 is meshed with the lifting mechanism 35. When the connecting handle 341 moves outward following the lower template 31, the transmission gear 1 342 meshes with the transmission guide rail 2, which is fixed. When the transmission gear 1 342 slides on the transmission guide rail 2 following the connecting handle 341, the transmission gear 1 342 will begin to rotate, thereby driving the transmission rod 343 and the transmission bevel gear 344 at one end to start rotating to perform transmission. At the same time, the connecting handle 341 is three-quarter circular, and when the connecting handle 341 rotates around the transmission guide rail 2, the connecting handle 341 will not fall out and can also rotate smoothly.

[0046] Reference Figure 7The lifting mechanism 35 includes a connecting bevel gear 351 arranged inside the lower template 31, the connecting bevel gear 351 and the transmission bevel gear 344 meshing with each other, and each group of top plates 38 has a connecting bevel gear 351 at the bottom, and multiple groups of connecting bevel gears 351 rotate synchronously through a transmission belt 2 352. A coaxial gear and a pulley are fixedly provided at the bottom of the connecting bevel gear 351, and a transmission gear 2 353 meshing with the coaxial gear of the connecting bevel gear 351 is provided inside the lower template 31. A ball screw 354 is provided on the top of the transmission gear 2 353, and a lifting nut 355 is movably provided on the outer side of the ball screw 354. The top of the lifting nut 355 A top plate 38 is provided on the top. When the connecting handle 341 moves outward with the lower template 31, the transmission gear 1 342 drives the transmission rod 343 and the transmission bevel gear 344 at one end thereof to start transmission. First, the transmission bevel gear 344 causes the connecting bevel gear 351 to start rotating, thereby the connecting bevel gear 351 drives the two sets of transmission gear 2 353 meshing with it to start rotating. The transmission gear 2 353 will drive the ball screw 354 at its top to rotate, and then the rotating ball screw 354 causes the jacking nut 355 on its outside to start moving upward, causing the top plate 38 on the top of the jacking nut 355 to move upward, and automatically ejecting the rubber product produced on the top of the top plate 38.

[0047] Reference Figure 3 The transmission guide rail 2 includes a guide rail base 21 fixedly arranged on one side of the top of the vulcanization base 12. Limiting grooves 22 are provided on both sides of the guide rail base 21. The size of the limiting grooves 22 is adapted to the size of the connecting handle 341. A rotating guide column 23 is provided inside the guide rail base 21 for rotation. A bar tooth 24 is provided inside the rotating guide column 23. The bar tooth 24 is engaged with the transmission gear 342. When the lower template 31 moves outward to a set distance, the rotating handle 36 can be held to control the lower template 31 so that the connecting handle 341 on one side rotates around the rotating guide column 23 in the guide rail base 21. The transmission gear 342 is meshed with the rotating guide column 23, and when the connecting handle 341 rotates around the rotating guide column 23, it will drive the rotating guide column 23 to rotate synchronously in the guide rail base 21, and limiting grooves 22 are equidistantly provided on both sides of the guide rail base 21. When the connecting handle 341 drives the rotating guide column 23 to rotate in the guide rail base 21, multiple groups of connecting handles 341 are just embedded in the inner side of the limiting grooves 22, so that the limiting grooves 22 limit the connecting handles 341, preventing the connecting handle 341 and the lower template 31 on one side from shaking left and right, resulting in the staff being unable to stably clean the rubber products and excess rubber on the surface of the lower template 31.

[0048] Specifically, when the connecting handle 341 follows the lower template 31 to move outward, the transmission gear 1 342 is meshed with the rotating guide post 23. Since the rotating guide post 23 is fixed, when the transmission gear 1 342 follows the connecting handle 341 to slide on the rotating guide post 23, the transmission gear 1 342 will start to rotate in the connecting handle 341, so that the transmission gear 1 342 will drive the transmission rod 343 and the transmission bevel gear 344 at one end to start rotating. The transmission bevel gear 344 will cause the connecting bevel gear 351 to start rotating, and the connecting bevel gear 351 drives the two sets of transmission gears 2 353 meshed with it to start rotating, and then the transmission gear 2 353 drives the ball screw 354 at its top to rotate, thereby rotating. The moving ball screw 354 causes the lifting nut 355 on its outside to start moving upward, causing the top plate 38 on the top of the lifting nut 355 to move upward, and automatically ejecting the rubber product produced on the top of the top plate 38. At the same time, the rotating connecting bevel gear 351 will drive the transmission belt 2 352 below it to rotate synchronously, and then the transmission belt 2 352 will synchronously drive multiple sets of connecting bevel gears 351 to rotate. Similarly, the rotating connecting bevel gear 351 drives the two sets of transmission gears 2 353 meshing with it, so that the multiple sets of top plates 38 inside the lower template 31 are lifted by the lifting nut 355, so that the rubber products on the top of the multiple sets of top plates 38 are demoulded and ejected, without the need for manual demoulding by the staff, reducing the labor intensity of the staff.

[0049] When the lower template 31 moves outward to a set distance along the guide rail base 1 21 and the push-out guide rail 4 on both sides thereof, the top plate 38 will completely push out the rubber product produced on its top and place the rubber product on the surface of the lower template 31. Then the staff holds the rotating handle 36 to control the lower template 31 so that the connecting handle 341 on one side rotates around the rotating guide column 23 in the guide rail base 1 21. Since the transmission gear 1 342 and the rotating guide column 23 are engaged with each other, when the connecting handle 341 rotates around the rotating guide column 23, it will drive the rotating guide column 23 to rotate synchronously in the guide rail base 1 21, and the guide Limiting grooves 22 are equidistantly provided on both sides of the rail base 21. When the connecting handle 341 drives the rotating guide column 23 to rotate in the guide rail base 21, multiple groups of connecting handles 341 are just embedded in the inner side of the limiting grooves 22, so that the limiting grooves 22 limit the connecting handles 341, preventing the connecting handles 341 and the lower template 31 on one side from shaking left and right, resulting in the staff being unable to stably clean the rubber products and excess rubber on the surface of the lower template 31. At this time, the lower template 31 forms a certain angle with the horizontal plane, and the staff can collect and clean the rubber products and excess rubber sheets on the surface of the lower template 31.

[0050] Example 3

[0051] Reference Figure 1-Figure 5, which is the third embodiment of the present invention, provides an intelligent demoulding device for a rubber shock-absorbing pad forming mold. A guide rod 13 is fixedly provided on the outside of the flat vulcanizer 11, and a control panel 14 is fixedly provided on one side of the guide rail base 41. The control panel 14 can control the start of the servo motor 15 and the up and down movement of the upper template 51. The control panel 14 is a prior art and will not be described in detail herein. The outer side of the guide rod 13 is provided with an upper template 51 located above the vulcanizing base 12. The internal movement of the vulcanizing base 12 is provided with two sets of plug-in structures 16. The plug-in structure 16 includes a plug-in column 161 connected to the driving end of the servo motor 15. The internal fixed structure of the plug-in column 161 is provided with a plug-in column 161. A spring column 162 is fixedly provided, and a clamping block 163 is fixedly provided at one end of the spring column 162. The two groups of plug-in structures 16 are transmitted through a transmission belt 164, and one end of a group of plug-in columns 161 is connected to the transmission end of the servo motor 15. The spring column 162 continuously provides elastic force to the clamping block 163. The internal movement of the upper template 51 is provided with a connecting plug-in column 52. When the plug-in column 161 is fully inserted into the connecting plug-in column 52 and rotated, the clamping block 163 and the connecting plug-in column 52 are stuck to each other, so that the connection between the plug-in column 161 and the connecting plug-in column 52 is tighter and firmer, and the rotating plug-in column 161 drives the connecting plug-in column 52 to rotate with it.

[0052] Reference Figure 1 、 Figure 10 and Figure 11 A transmission gear three 53 is fixedly provided on the outer side of the connecting column 52, and a transmission gear four 54 meshing with the transmission gear three 53 is movably provided inside the upper template 51. A diamond-shaped knife 55 is fixed on one side of the transmission gear four 54. An upper mold 56 located inside the transmission gear four 54 is fixed inside the upper template 51. The upper mold 56 and the transmission gear four 54 are movable and rotated. A plurality of lower mold cavities 321 are provided inside the lower template 31. A guide slope 322 is provided on the outer side of the top of the lower mold cavity 321. When the upper mold 56 and the lower mold cavity 321 are closed, the outer mold of the rubber product is formed. The transmission gear three 53 on the outer side is driven to rotate by the connecting column 52, and then the transmission gear three 53 drives the transmission gear four 54 to drive the diamond-shaped knife 55 above it to rotate around the outer side between the upper mold 56 and the lower mold cavity 321.

[0053] Reference Figure 9 The ejection guide rail 4 includes a guide rail base 2 41 fixedly arranged on the other side of the top of the vulcanization base 12. A transmission chain tooth 43 is provided inside the guide rail base 2 41. A transmission shaft 42 is engaged with the transmission chain tooth 43. The other end of the transmission shaft 42 is connected to the servo motor 15. A clutch 17 is provided between the two. The bottom of the rotating handle 36 is provided with a bar tooth 2 37 that meshes with the transmission chain tooth 43. The interlocking method here is the existing technology and is not limited in this article.

[0054] Specifically, the staff first sprays the release agent on the bottom of the lower mold cavity 321 and the upper mold 56, and then places the measured rubber sheets on the top of the top plate 38 in sequence. Then, the staff starts the clutch 17 through the control panel 14, controls the servo motor 15 to drive the transmission shaft 42 to rotate, and then causes the transmission chain teeth 43 to rotate in the opposite direction to drive the rotating handle 36 and the lower mold plate 31 on one side to move inward until the lower mold plate 31 moves to the bottom of the upper mold plate 51. During the movement of the lower mold plate 31, the guide column 23 is first rotated to cause the transmission gear 1 342 engaged therewith to rotate in the opposite direction, thereby controlling the transmission rod 343 and the transmission bevel gear 344 at one end thereof to rotate in the opposite direction, and causing the connecting bevel gear 351, the transmission gear 2 353, and the ball screw 354 to rotate in the opposite direction, thereby causing the lifting nut 355 to drive the top plate 38 on its top to move downward until the lower mold plate 31 moves to just below the bottom of the upper mold plate 51. At this time, the top plate 38 is just at the bottom of the inner wall of the lower mold cavity 321.

[0055] Then the upper template 51 moves downward along the guide rod 13 and closes together with the lower template 31. During the closing process, the pin 161 will be inserted into the connecting pin 52 until the upper template 51 and the lower template 31 are completely closed. At this time, the pin 161 is completely inserted into the connecting pin 52. At the same time, the upper mold 56 and the lower mold cavity 321 on the upper template 51 and the lower template 31 are also closed together to form a mold. Then, the outside of the lower mold cavity 321 is heated to cause the rubber raw material inside the lower mold cavity 321 to undergo a vulcanization reaction.

[0056] During the vulcanization process, the clutch 17 is first started to disconnect the servo motor 15 from the transmission shaft 42, thereby preventing the lower template 31 from being automatically pushed out during the rubber vulcanization process. At this time, the servo motor 15 will drive the pin 161 to rotate, and then drive the block 163 to rotate on the inner side of the connecting pin 52 until the block 163 is aligned with the notch inside the connecting pin 52. At this time, the spring column 162 causes the block 163 to be stuck with the notch and provides pressure on the block 163, so that the connection between the pin 161 and the connecting pin 52 is tighter and firmer, so that the rotating pin 161 drives the connecting pin 52 to rotate with it, and then the connecting pin 52 drives the transmission gear three 53 on its outer side to rotate, and makes the transmission gear three 53 meshed with the transmission gear three 53 Gear four 54 rotates around the outer side of the upper mold 56. When the upper mold 56 and the lower mold cavity 321 are completely closed, the diamond knife 55 just passes through the connection between the two. At the same time, there is a certain distance between the top of the diamond knife 55 and the guide bevel 322. During the rubber vulcanization process, excess rubber will overflow from the joint of the upper mold 56 and the lower mold cavity 321. At this time, the diamond knife 55 rotates on its outer side to scrape off the overflowed rubber material, thereby preventing the overflowed rubber from adhering to the outer side of the rubber shock absorber to form burrs, which requires staff to perform secondary trimming and cleaning. The outer side of the diamond knife 55 is in a rotating state, and the overflowed rubber material is scraped off in time. The scraped rubber material will be distributed on the outer side of the lower mold cavity 321 along the guide bevel 322.

[0057] After the vulcanization of the rubber product is completed, the servo motor 15 is first controlled to stop working through the control panel 14, and then the upper template 51 is controlled to move upward along the guide rod 13 to separate from the lower template 31, so that the pin 161 is pulled out of the connecting pin 52, and the pin 161 causes the block 163 to pop out again and return to its original position. After the upper template 51 returns to its original position, the servo motor 15 and the clutch 17 are restarted at this time, so that the clutch 17 drives the transmission shaft 42 to drive the transmission chain teeth 43 at one end thereof to rotate, and then drives the rotating handle 36 engaged with the transmission chain teeth 43 to move outward. At this time, the rotating handle 36 drives the lower template 31 to slide and be pushed out on the rotating guide column 23 and the transmission chain teeth 43. In this process, the rubber product inside the lower mold cavity 321 is automatically pushed out by the top plate 38 until the lower template 31 moves outward to the set distance. At this time, the staff can hold the rotating handle 36 to control the lower template 31 so that the connecting handle 341 on one side revolves around the rotating guide column 23 When the gear 341 is in the unlock state, the gear 342 is locked and the gear 343 is unlocked, so the gear 341 is unlocked and the gear 343 is unlocked.
