Description

Technical Field

[0001] This invention relates to the field of rubber pad injection molding machine technology, specifically a rubber pad injection molding machine and a rubber pad with waste recycling function. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.

[0003] The working principle of a rubber pad injection molding machine is similar to that of a syringe. It uses the thrust of a screw (or plunger) to inject the plasticized molten material (i.e., viscous flow state) into a closed mold cavity, and then obtains the product after cooling, cooling down and solidification.

[0004] For example, patent application CN116476335A discloses a rubber pad injection molding machine, including a first partition plate fixedly installed on one side of the upper surface of a support platform, a fixed mold fixedly installed on the side of the first partition plate near the support platform via a pad, an injection port being opened through the inner wall of the molding cavity of the fixed mold, and an clearance groove being opened through one side surface of the first partition plate; a second partition plate fixedly installed on the other side of the upper surface of the support platform, a cylinder fixedly installed on the side of the second partition plate away from the first partition plate, the output end of the cylinder passing through the second partition plate and fixedly installed with a sealing plate, a moving mold being fixedly installed on the side of the sealing plate near the first partition plate; a cutting assembly for cutting rubber columns on one side of the molded part is installed on the upper surface of the sealing plate; and a material groove is opened through the middle of the upper surface of the support platform.

[0005] However, the aforementioned patent application still has some problems. When performing the demolding process, the molten raw material is injected into the closed mold cavity. Although the rubber in the mold is cooled by the cooling chamber, the rubber pad in the mold still has a certain temperature after cooling. Since the demolding of the rubber pad is mostly done manually, the operator needs to be in contact with the high temperature rubber pad for a long time, which may cause burns to the operator's hands and cause the demolding of the rubber pad to fail.

[0006] Therefore, how to demold the rubber pad is a problem that needs to be solved. Summary of the Invention

Compared to manual demolding, this device can complete the demolding process without human intervention. During demolding, the demolding motor drives the drive shaft to rotate, which in turn drives the drive wheel to rotate. A first belt causes a transmission wheel on one of the drive shafts to rotate, and a second belt drives a driven wheel to rotate, thus enabling the driven shaft to drive... The demolding roller rotates, positioning itself on the width and height of the rubber pad. This rotation applies a thrust towards the transport assembly, and with the assistance of the screw slide, the rubber pad moves away from the mold. The rotation also lifts the portion of the rubber pad that has detached from the mold, positioning it between the two demolding rollers. Simultaneously, the screw slide moves the demolding roller across the mold surface, completing the demolding process. Compared to traditional manual demolding, this device does not injure operators. Furthermore, based on the strain of the rubber pad, it can be coordinated with the transport assembly to achieve various demolding methods for the rubber pad. Attached Figure Description

[0049] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0050] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0051] This invention discloses a rubber pad injection molding machine with waste recycling function and a rubber pad, as described above. Figures 1-10A rubber pad injection molding machine with waste recycling function includes:

[0052] The system comprises a mold into which rubber is injected through injection holes; a cooling chamber 1 for cooling and shaping the rubber; a transport platform 2 symmetrically positioned on both sides of the cooling chamber 1 for transporting the mold; a demolding assembly 3 mounted on the transport platform 2 for demolding the molded product; and a negative pressure device for recycling waste materials generated during the rubber pad production process. The demolding assembly 3 includes two lead screw slides 31 symmetrically positioned on the transport platform 2, a lifting cylinder connected to the lead screw slides 31, a housing 32 connected to the output end of the lifting cylinder, demolding rollers 35 connecting the two housings 32, a transmission part 34 and an adjustment part 36 connected to the demolding rollers 35 and located on the housings 32, and a demolding motor 33 connected to one of the transmission parts 34. Through the operation of the demolding assembly 3, the rubber pad is peeled and demolded, completing the injection molding process.

[0053] The transmission unit 34 includes a drive shaft 341 located at the output end of the demolding motor 33, two drive wheels 342 sleeved on the drive shaft 341, two transmission shafts 344 and two driven shafts 348 disposed in the housing 32, two transmission wheels 343 sleeved on the transmission shafts 344, driven wheels 347 sleeved on the driven shafts 348, a first belt 345 for connecting one of the drive wheels 342 and one of the transmission wheels 343, and a belt for connecting the same drive shaft 344. Another transmission wheel 343 and a second belt 346 for the driven wheel 347; the transmission part 34 also includes an arc-shaped sliding groove and an arc-shaped limiting guide rail 3410 provided on the housing 32, and two limiting wheels 349 sleeved on the driven shaft 348; the limiting wheels 349 are located in the sliding groove and abut against the limiting guide rail 3410; the driven shaft 348 is connected to the demolding roller 35; by rotating the two demolding rollers 35 and cooperating with the movement of the screw slide 31, the rubber pad is initially demolded from the mold, and in conjunction with... Two rotating demolding rollers 35 perform a secondary demolding operation on the rubber pad. The demolding motor 33 drives the drive shaft 341 to rotate, which in turn drives the drive wheel 342. Through the first belt 345, the drive wheel 343 on one of the drive shafts 344 rotates, and through the second belt 346, the driven wheel 347 rotates. This, in turn, drives the demolding roller 35 to rotate via the driven shaft 348. At this time, the demolding roller 35 can be located on the width and height surface of the rubber pad. Due to the rotation of the demolding roller 35, a thrust can be applied to the rubber pad in the direction of the conveying component 7. With the cooperation of the screw slide 31, the rubber pad can move away from the mold. Due to the rotation of the demolding roller 35, the part of the rubber pad that has been removed from the mold is lifted up, so that this part can be located between the two demolding rollers 35. At the same time, driven by the screw slide 31, the demolding roller 35 moves on the mold surface to complete the demolding of the rubber pad.

[0054] The transmission unit 34 further includes an arc-shaped sliding groove and an arc-shaped limiting guide rail 3410 disposed on the housing 32, and two limiting wheels 349 sleeved on the driven shaft 348; the limiting wheels 349 are located in the sliding groove and abut against the limiting guide rail 3410; the driven shaft 348 is connected to the demolding rollers 35; by rotating the two demolding rollers 35 in coordination with the movement of the lead screw slide 31, the rubber pad is initially demolded from the mold, and then the two rotating demolding rollers 35 perform a secondary demolding operation on the rubber pad; the adjustment unit 36 includes an adjusting motor 361 fixedly mounted on the housing 32, an adjusting screw 362 connected to the output end of the adjusting motor 361, an adjusting block 363 sleeved on the adjusting screw 362, a movable shaft 364 connected to the adjusting block 363, a movable seat 365 sleeved on the movable shaft 364, and a connecting rod 366 movably connected to the movable seat 365; the other end of the connecting rod 366 is disposed on the driven shaft 348, and the driven shaft 348 moves in the sliding groove by the movement of the connecting rod 366;

[0055] During the demolding process, the adjusting motor 361 starts to work. The moving adjusting motor 361 can drive the adjusting screw 362 to start rotating, changing the position of the adjusting block 363 on the adjusting screw 362, changing the position of the movable shaft 364 and the movable seat 365, and through the set connecting rod 366, the limiting wheel 349 can move in the sliding groove, thereby playing a limiting role for the rubber pad.

[0056] During the above process, the position adjustment between the demolding rollers 35 is completed based on the strain of the rubber pad. When the strain of the rubber pad is large, that is, when the physical quantity of deformation of the object under force is large, after the demolding work of a part of the rubber pad is completed, the demolding motor 33 stops working, and the adjusting motor 361 starts working. The moving adjusting motor 361 can change the distance between the two demolding rollers 35, so that the demolding rollers 35 abut against the rubber pad and clamp it. As the lead screw slide 31 moves, the rubber pad forms a U-shaped structure. Then, the conveying component 7, driven by the conveying robot 5, can be inserted into the U-shaped rubber pad, and then the subsequent processing of the rubber pad... The conveying operation of the pad; conversely, when the strain of the rubber pad is small, there is a preset gap between the two demolding rollers 35 during the demolding process, and the demolding rollers 35 are both rotating during the demolding process. At this time, the demolding roller 35 close to the mold can apply a pulling force to the bottom surface of the rubber pad, which facilitates the demolding of the rubber pad, while the other demolding roller 35 plays a limiting role for the rubber pad, preventing the rubber pad from tilting up too much, which would cause the rubber pad to collide with other devices. Then, the conveying component 7 is located at the bottom of the rubber pad, which can then play a supporting role for the rubber pad. According to the cooperation between the transmission part 34 and the conveying component 7, the injection molding of rubber pads with different strains can be completed.

[0057] This device also includes a handling robot 5 and a cutting assembly 6, a centering and limiting assembly 4 mounted on the transport platform 2, and a handling assembly 7 mounted on the handling robot 5. The handling assembly 7 includes a screw drive mechanism 71 fixedly mounted on the handling robot 5, two movable seats 72 mounted on the screw drive mechanism 71, a lifting cylinder 73 connected to the movable seats 72, a lifting block 74 connected to the output end of the lifting cylinder 73, a lifting frame 75 connected to the lifting block 74, a mounting base 76 connected to the lifting frame 75, and a support roller 77 mounted on the mounting base 76. The screw drive mechanism 71 can drive the movable seats 72 to move closer or further apart. When it is necessary to place the rubber pad in a predetermined position, the support roller 77... Located in or at the bottom of a U-shaped rubber pad, the transport robot 5 and the lead screw drive mechanism 71 (existing technology, wherein the lead screw is a bidirectional lead screw) begin to work. The moving lead screw drive mechanism 71 drives the bidirectional lead screw to rotate, thereby adjusting the distance between the two support rollers 77. Then, the lifting cylinder 73 starts to work, and the moving lifting cylinder 73 drives the lifting block 74 to move, thereby driving the lifting frame 75 to start moving, raising the height of the support rollers 77, completing the support and unfolding work of the rubber pad, so that it can be positioned in the predetermined cutting position, which is convenient for the cutting device to cut it. At the same time, the support rollers 77 can keep the rubber pad in an unfolded state, avoiding excessive deformation of the rubber pad, which would lead to failure of the rubber pad cutting work.

[0058] The cutting assembly 6 includes a worktable 61, a limiting part 62, a first cutting part 64, and a second cutting part 65 disposed on the worktable 61, and driving parts 63 symmetrically disposed on both sides of the limiting part 62; the driving part 63 includes a support base 631 fixedly mounted on the worktable 61, a rotating base 634 movably connected to the support base 631, a drive motor 632 fixedly mounted on the rotating base 634, an abutment wheel 633 connected to the output end of the drive motor 632, a rotating shaft 637 disposed on the support base 631, a drive cylinder 635 connected to the rotating shaft 637, and a connecting rod 636 disposed at the output end of the drive cylinder 635; the connecting rod 636... 36 is connected to the rotating seat 634; after the rubber pad is placed, the drive cylinder 635 starts to work. The moving drive cylinder 635 can drive the connecting rod 636 to move. At this time, the moving connecting rod 636 can make the rotating seat 634 rotate around the support seat 631, so that the abutting wheel 633 can abut against the rubber pad. Then the drive motor 632 starts to work, which can drive the abutting wheel 633 to rotate, thereby pushing the rubber pad so that it can pass through the cutting area and complete the cutting work. At the same time, the abutting wheel 633 can not only push, but also initially limit the rubber pad to ensure that the pressure plate 626 can perform secondary limiting work on it.

[0059] The limiting part 62 includes a movable cylinder 621 and a rotating shaft 622 mounted on the worktable 61, a limiting rod 623 connected to the rotating shaft 622, a protrusion 627 on the limiting rod 623, a transmission component for connecting the movable cylinder 621 and the limiting rod 623, a movable rod 625 connected to the limiting rod 623, and a pressure plate 626 movably connected to the movable rod 625; the pressure plate 626 has at least two notches, which are the cutting areas of the first cutting part 64 and the second cutting part 65, respectively; the transmission component includes a rotating rod 628 movably connected to the worktable 61, a rotating rod 624 connected to the rotating rod 628, a torsion spring 629 for connecting the rotating rod 624 and the limiting rod 623, and a drive block 629 mounted on the output end of the movable cylinder 621 and in the circumferential direction. 210 and the protruding end 6211; the protruding end 6211 abuts against the rotating rod 624, and the driving block 6210 abuts against the protruding block 627; when it is necessary to limit the cutting, the movable cylinder 621 starts to work. The moving movable cylinder 621 can drive the protruding end 6211 to start moving. The moving protruding end 6211 can drive the rotating rod 624 to rotate around the rotating rod 628. Then, the torsion spring 629 can push the limiting rod 623 to start working. Adjusting the end position of the limiting rod 623 changes the position of the movable rod 625 and the pressure plate 626, completing the limiting work of the rubber pad. By pressing down, the rubber pad is squeezed and limited, thereby completing the cutting of the rubber pad. At the same time, the torsion spring 629 is set in this device to keep it in a movable squeezing state to avoid damage to the rubber pad.

[0060] The second cutting section 65 includes a base 651 and a slide 656 fixedly mounted on the workbench 61, a rotary motor 652 connected to the base 651, a first rotating arm 653 located at the output end of the rotary motor 652, a second rotating arm 654 and a cutting blade 6510 connected to the first rotating arm 653, a lifting motor 657 fixedly connected to the slide 656, a gear 658 located at the output end of the lifting motor 657, a rack 659 meshing with the gear 658 and movably connected to the slide 656, and a U-shaped frame 655 connected to the rack 659; the free end of the second rotating arm 654 has an arc, and the free end of the second rotating arm 654 is located in the groove of the U-shaped frame 655; when cutting is required... During operation, the position of the cutting blades can be adjusted via the rotating disc and cylinder. Simultaneously, the lifting motor 657 starts working, which drives the gear 658 to move. The gear 658 then moves the rack 659, thereby driving the U-shaped seat to adjust the position of the second rotating arm 654, thus changing the adjustment range of the cutting blade 6510. Then, the rotating motor 652 starts working, which drives the first rotating arm 653 to rotate, changing the cutting angle adjustment of the cutting blade 6510 to facilitate the cutting edge trimming of the rubber pad. After the cutting edge trimming of the rubber pad is completed, the removed burrs are adsorbed and recycled using a negative pressure device, thus achieving recycling.

[0061] A rubber pad includes a plurality of vent holes disposed on the rubber pad.

[0062] In a further embodiment, the first cutting part 64 and the lead screw transmission mechanism 71 are existing technologies, including a rotating disk, a cylinder connected to the rotating disk, and a cutting scissors disposed at the output end of the cylinder.

[0063] Working principle description: The plasticized molten raw material is injected into the closed mold cavity. After cooling and solidification in the cooling chamber 1, it is transported out from another transport platform 2. Then, the mold is positioned in a predetermined position by the centering limit component 4. Then, the demolding motor 33 drives the drive shaft 341 to rotate. The drive shaft 341 drives the drive wheel 342 to rotate. Through the cooperation of the first belt 345, the drive wheel 343 on one of the drive shafts 344 rotates. Through the second belt 346, the driven wheel 347 rotates, which in turn drives the demolding roller 35 to rotate through the driven shaft 348. At this time, The demolding roller 35 can be located on the width and height surface of the rubber pad, and due to the rotation of the demolding roller 35, a thrust can be applied to the rubber pad in the direction of the conveying assembly 7. With the cooperation of the screw slide 31, the rubber pad can be moved away from the mold. Due to the rotation of the demolding roller 35, the rubber pad part that has been removed from the mold is lifted. During the demolding process, the adjusting motor 361 starts to work. The moving adjusting motor 361 can drive the adjusting screw 362 to start rotating, change the position of the adjusting block 363 on the adjusting screw 362, change the position of the movable shaft 364 and the movable seat 365, and through the connecting rod 366, the limiting wheel 349 can move in the sliding groove, thereby limiting the rubber pad.

[0064] When the rubber pad needs to be placed in a predetermined position, the support roller 77 is located in the U-shaped rubber pad or at the bottom of the rubber pad. Then, the handling robot 5 and the screw drive mechanism 71 (existing technology, in which the screw is a bidirectional screw) start working. The moving screw drive mechanism 71 can drive the bidirectional screw to rotate, thereby adjusting the distance between the two support rollers 77. Then, the lifting cylinder 73 starts working. The moving lifting cylinder 73 can drive the lifting block 74 to move, thereby driving the lifting frame 75 to start moving, raising the height of the support roller 77, completing the support and unfolding work of the rubber pad, so that it can be placed in the predetermined cutting position.

[0065] After the rubber pad is placed, the drive cylinder 635 starts working. The moving drive cylinder 635 drives the connecting rod 636 to move. The moving connecting rod 636 causes the rotating seat 634 to rotate around the support seat 631, so that the abutting wheel 633 can abut against the rubber pad. Then the drive motor 632 starts working, which drives the abutting wheel 633 to rotate, thus pushing the rubber pad through the cutting area. When it is necessary to limit the cutting, the movable cylinder 621 starts working. The moving movable cylinder 621 drives the protruding end 6211 to move. The moving protruding end 6211 drives the rotating rod 624 to rotate around the rotating rod 628. Then, the torsion spring 629 pushes the limiting rod 623 to start working. Adjusting the end position of the limiting rod 623 changes the position of the movable rod 625 and the pressure plate 626, thus completing the limiting work of the rubber pad.

[0066] When cutting is required, the position of the cutting blade can be adjusted by the rotating disk and cylinder. At the same time, the lifting motor 657 starts working, and the moving lifting motor 657 drives the gear 658 to work. The moving gear 658 drives the rack 659 to move, which in turn drives the U-shaped seat to work, adjusting the position of the second rotating arm 654, thereby changing the adjustment range of the cutting blade 6510. Then, the rotating motor 652 starts working, and the moving rotating motor 652 drives the first rotating arm 653 to rotate, changing the cutting angle adjustment of the cutting blade 6510, which facilitates the cutting edge cutting of the rubber pad by the cutting blade 6510.
