[0001] The invention relates to the technical field of slipper injection molding, in particular to a processing injection molding device for deodorizing and antibacterial slippers. Background Art

[0002] Slippers are a common type of shoes in daily life, and the demand is relatively large. Existing slipper molding mainly includes injection molding and compression foaming molding. In the injection molding process, the raw materials are heated and injected into the mold cavity under high pressure. The raw materials in the mold are solidified after cooling to make slippers. In order to make the slippers have the effect of deodorization and antibacterial, antibacterial agents are generally added before the raw materials are melted, so as to give the slippers after injection molding the deodorization and antibacterial properties.

[0003] In order to improve the production efficiency of slippers, generally, multiple molds for slipper injection molding are set. Multiple molds will be installed on a disc turntable. After the turntable drives the mold through the injection port of the injection molding machine, the injection molding machine will inject the raw material into the mold. The mold after injection molding is rotated out from the bottom of the injection molding machine along the turntable. The mold injected with raw materials is cooled and solidified as the turntable moves. The worker will take out the solidified slippers and close the mold. The empty mold will move toward the bottom of the injection molding machine again, and the cycle will continue. This is a disc-type slipper processing injection molding machine, and another multi-station slipper injection molding machine uses a conveyor belt to horizontally transfer the mold in sequence. In the way of injection molding-cooling-opening, it is not difficult to find that although the existing multi-station slipper processing injection molding equipment is highly efficient, it has the defect of occupying a large area.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 10 As shown, the present invention includes the following embodiments:

[0032] Embodiment 1: A deodorizing and antibacterial slipper processing injection molding equipment, comprising an injection molding machine 1 and a barrel 11 above the injection molding machine 1; the output end of the injection molding machine 1 is connected to an injection molding plate 13 through a cylinder 12; the injection molding hole on the injection molding plate 13 is connected to the inside of the injection molding machine 1 through an injection molding tube; one end of the injection molding tube is fixedly connected to the injection molding plate 13, and the other end is movably sealed and connected to the injection molding machine 1; a frame 2 is provided at the rear side of the injection molding machine 1; the upper end of the frame 2 is rotatably connected to a driving disk 22 through a driving shaft 21, and the lower end is rotatably connected to a driven disk 22 through a driven shaft 23 The driven disk 24 is dynamically connected to the driven disk 24; the outer wall of the driving disk 22 and the driven disk 24 is transmission-connected to the chain 25; the chain 25 is provided with a mold assembly 3 on the side facing the injection molding machine 1; a plurality of the mold assemblies 3 are evenly distributed along the transmission direction of the chain 25; the mold assembly 3 can be moved to the bottom of the injection plate 13 under the transmission of the chain 25; the feed hole on the mold assembly 3 is aligned with the injection hole on the injection plate 13 after movement; the side of the frame 2 facing away from the injection molding machine 1 is fixedly connected to the motor 26; the output shaft of the motor 26 is fixedly connected to the driving shaft 21.

[0033] In this embodiment, the mold assembly 3 is composed of an upper mold, a mold core and a lower mold; the upper mold, the mold core and the lower mold are hinged to each other near the end of the chain 25; the upper mold and the lower mold are locked away from the end of the chain 25; the lower surface of the lower mold is fixedly connected to the mold sleeve 31; the chain 25 is connected to the connecting rod 4 from front to back; the front end of the connecting rod 4 is connected to the mold sleeve 31.

[0034] Specifically, in the prior art, when producing antibacterial slippers, first select EVA raw materials that meet the production requirements, such as ethylene-vinyl silicate copolymer, etc., and professionals prepare raw materials such as foaming agent, elastomer, antibacterial agent, etc.; among which, antibacterial agent includes but is not limited to antibacterial silver ion, nano silver antibacterial powder, inorganic silver ion antibacterial agent, silver ion silicone antibacterial agent, etc.;

[0035] Secondly, after the raw materials are prepared, the antimicrobial agent and EVA raw materials are mixed to the required standard ratio, and then put into the internal mixer for mixing and kneading to ensure that the antimicrobial agent is evenly distributed in the raw materials and the antimicrobial effect is more effectively improved;

[0036] Next, after ensuring that the mixed raw materials are free of impurities and color difference, professionals will be responsible for stirring them evenly and then pull them to the pre-adjusted injection machine to start injection;

[0037] Finally, during the process of looking at the hot melt, under the action of the gun and pressure, the hot melt is injected into the mold to start vulcanization. After the vulcanization time is up, the mold is automatically opened to take the finished slippers out of the mold, put on the last, cool, shape, trim and inspect. In this way, a pair of deodorizing, elastic, wear-resistant, lightweight and antibacterial slippers are completed.

[0038] In the present invention, after the staff adds the slipper injection molding raw materials and the antibacterial agent into the barrel 11 above the injection molding machine 1, the barrel 11 is covered. A stirring unit and a heating unit are attached inside the barrel 11, so that the raw materials and the antibacterial agent in the barrel 11 are stirred and melted. The addition of the antibacterial agent makes the molded slippers have antibacterial and deodorizing properties. In addition, the injection molded slippers are integrally molded, which is more environmentally friendly, not easy to break, and has better durability than adhesive slippers. After the raw materials and the antibacterial agent in the barrel 11 are mixed to form the slipper material, the motor 26 controls the rotation of the driving shaft 21, and the driving shaft 21 will drive the driving disk during the rotation. 22 rotates, the outer wall of the active disk 22 and the driven disk 24 is connected to the chain 25, so the active disk 22 will drive the chain 25 to drive during the rotation process, and the chain 25 will drive multiple connecting rods 4 and the mold assembly 3 to move along the transmission direction of the chain 25 during the transmission process. The chain 25 is vertically arranged, so a part of the connecting rod 4 and the mold assembly 3 moves from top to bottom, and another part of the mold assembly 3 moves from bottom to top, thus forming a cycle. Under the drive of the chain 25, multiple mold assemblies 3 will move to the bottom of the injection plate 13 in turn. After each mold assembly 3 moves to the bottom of the injection plate 13, the chain 25 will stop for a period of time;

[0039] When the chain 25 stops transmitting, the injection molding plate 13 will move downward during the extension of the cylinder 12. During the downward movement of the injection molding plate 13, the injection molding tube on the upper surface and the injection molding machine 1 will be driven to move. The injection molding tube is movably and sealedly connected to the inside of the injection molding machine 1. After the lower surface of the injection molding plate 13 contacts the upper surface of the upper mold in the mold assembly 3, it is sealed. The injection holes on the lower surface of the injection molding plate 13 are aligned with and connected to the feed holes on the upper surface of the upper mold. The exhaust holes on the lower surface of the injection molding plate 13 are aligned with and connected to the exhaust holes on the upper surface of the upper mold. Then the injection molding machine 1 starts working and the injection molding machine 1 pushes the material in the barrel 11 along the The injection tube enters the injection hole, and finally is injected into the feed hole along the injection hole, so that the material enters the interior of the mold assembly 3, and the gas inside the mold assembly 3 is discharged along the exhaust hole and the exhaust hole, thus completing the process of injecting the material into one of the mold assemblies 3. In order to exhaust the gas inside the mold assembly 3 more thoroughly, the exhaust hole can also assist the air pump to extract the gas inside the mold assembly 3 to the outside. After completing the injection of the material inside one of the mold assemblies 3, the control cylinder 12 is shortened to drive the injection plate 13 to move upward, and the injection plate 13 will be out of contact with the upper mold;

[0040] The chain 25 is driven by the motor 26 to transmit again. The chain 25 will drive the mold assembly 3 that has completed the injection molding to move away from the bottom of the injection molding plate 13 and move from bottom to top. The next mold assembly 3 will move to the bottom of the injection molding plate 13 for a new round of injection molding. The mold assembly 3 that has completed the injection molding will move up to the top and then move down. During this process, the material in the mold assembly 3 will be cooled and solidified. During the injection molding process of one of the mold assemblies 3, the staff will open the lock on the front side of the mold assembly 3 during the pause process, lift the upper mold, remove the slippers on the mold core, and at the same time remove the waste in the feed hole, and then merge and lock the upper mold cover to complete the slipper molding process.

[0041] In this embodiment, the chain 25 drives multiple mold assemblies 3 to move up and down and pass directly under the injection plate 13, so that the mold assembly 3 can complete the slipper injection molding process during the up and down movement. Compared with the existing slipper injection molding equipment, the present invention realizes multi-station injection molding while ensuring a small footprint.

[0042] Embodiment 2: the connecting rod 4 is rotatably connected to the chain 25 ; the rear end of the connecting rod 4 is fixedly connected to the counterweight 6 ; the mass of the counterweight 6 is greater than the mold assembly 3 .

[0043] During the transmission process of the chain 25 driving the connecting rod 4 and the mold assembly 3, since the mass of the counterweight block 6 is greater than that of the mold assembly 3, and the counterweight block 6 is located below the corresponding mold assembly 3, the mold assembly 3 is tilted upward by utilizing the function of the connecting rod 4 to ensure that the mold assembly 3 is kept in an upright state during the transmission process of the chain 25, thereby preparing for the subsequent injection molding of the injection plate 13. In addition, during the transmission process of the chain 25, the mold assembly 3 will shake. The mold assembly 3 is stable under the pressure of the injection molding plate 13, but after the mold assembly 3 is separated from the injection molding plate 13, the mold assembly 3 will shake with the rotation of the connecting rod 4. During the back and forth swinging process of the mold assembly 3, the internal material can be shaken, so that the material is shaken before solidification, so that the material in the mold assembly 3 is more substantial, and the quality of the slippers after molding is slightly improved.

[0044] Embodiment 3: The front side of the frame 2 is fixedly connected to the cooling box 5; the driving shaft 21 penetrates the cooling box 5 front and back and is rotatably sealed with the cooling box 5; the driving disk 22 is located on the inner side of the cooling box 5; the bottom of the cooling box 5 is provided with an inlet 51 and an outlet 52; the upper half of the chain 25 is located inside the cooling box 5; the chain 25 can drive the mold assembly 3 and the counterweight 6 to enter the cooling box 5 along the inlet 51; the chain 25 can drive the mold assembly 3 and the counterweight 6 to move out of the cooling box 5 along the outlet 52.

[0045] In this embodiment, the lateral positions of the box inlet 51 and the box outlet 52 are fixedly connected to the shielding curtain 53 .

[0046] After the injection plate 13 contacts the mold assembly 3, the injection molding machine 1 injects the material into the mold assembly 3. As the injection plate 13 separates from the mold assembly 3, the mold assembly 3 after the injection molding is completed moves from bottom to top as the chain 25 starts again. The mold assembly 3 and the corresponding counterweight block 6 will enter the box inlet 51. Since the lateral position of the box inlet 51 is fixedly connected to the shielding curtain 53, the shielding curtain 53 bends after being squeezed open by the mold assembly 3. As the mold assembly 3 continues to move upward, the mold assembly 3 will squeeze the shielding curtain 53 open and enter the interior of the cooling box 5. As the mold assembly 3 and the corresponding counterweight block 6 Continuing to move upward, the mold assembly 3 will pass over the shielding curtain 53, and the shielding curtain 53 will cover the box inlet 51 again. At the moment when the shielding curtain 53 is out of contact with the mold assembly 3, the mold assembly 3 will drive the connecting rod 4 and the chain 25 to move under the toggle, and under the counterweight of the counterweight block 6, the mold assembly 3 will swing back and forth in front of the chain 25. The material inside the mold assembly 3 will flow with the swing of the mold assembly 3, so that the material inside the mold assembly 3 will better fill the remaining gap, and the material inside the mold assembly 3 will also be further mixed before solidification, so that the quality of the slippers after molding is improved;

[0047] When the mold assembly 3 enters the cooling box 5, the shielding curtain 53 can also scrape the waste on the mold assembly 3 so that the waste is scraped away, and the waste will bounce away as the shielding curtain 53 is reset. Even if the waste is not bounced away, it can be cleaned separately after solidification. The shielding curtain 53 can be made of metal or non-metal, and its surface is coated with a release agent, so that it is difficult for waste to adhere to the shielding curtain 53. In addition, the shielding curtain 53 can increase the friction on the surface to increase the friction with the mold assembly 3; the mold assembly 3 is quickly cooled by the cooling components inside the cooling box 5 during the transmission of the chain 25 in the cooling box 5, and the cold air in the cooling box 5 is retained to the maximum extent by the shielding curtain 53, and the material in the mold assembly 3 is solidified and formed in the cooling box 5. After the material inside the mold assembly 3 is formed, it will be moved out from the outlet 52 as the chain 25 drives it. As the mold assembly 3 pauses, the mold assembly 3 is opened and the slippers are taken out.

[0048] Embodiment 4: The mold sleeve 31 is movably sleeved on the outer wall of the connecting rod 4; when the counterweight block 6 is in the upright state, the outer wall of the connecting rod 4 is horizontally symmetrically provided with L-shaped grooves 42; the other end of the L-shaped groove 42 is connected to the front end face of the connecting rod 4; the L-shaped groove 42 is slidably connected to the L-shaped strip 43; the L-shaped strip 43 is connected to the inner wall of the L-shaped groove 42 by a spring 44 on one side close to each other; the ends of the L-shaped strip 43 initially extend out of the L-shaped groove 42; when the mold assembly 3 is in the upright state, the inner wall of the mold sleeve 31 is horizontally symmetrically provided with clamping grooves 32; the clamping grooves 32 correspond to the L-shaped grooves 42 after the mold sleeve 31 is sleeved on the outer wall of the connecting rod 4; the ends of the L-shaped strip 43 can be inserted into the corresponding clamping grooves 32.

[0049] In this embodiment, a third guide surface 431 is provided at one end of the L-shaped strip 43 that is inserted into the slot 32 and is away from the chain 25 ; the mold sleeve 31 can squeeze the third guide surface 431 to allow the two L-shaped strips 43 to move toward each other.

[0050] In this embodiment, a vertical groove 61 is vertically provided on the side of the counterweight block 6 facing away from the chain 25; the vertical groove 61 penetrates the counterweight block 6 up and down; the outer wall of the frame 2 is fixedly connected to the vertical bar 7 through an L-shaped rod 71; the lower end of the vertical bar 7 is not lower than the driven shaft 23; the lateral width of the vertical groove 61 is adapted to the lateral width of the vertical bar 7; the vertical bar 7 can be inserted into the corresponding vertical groove 61 during the top-down movement of the counterweight block 6.

[0051] In this embodiment, the vertical groove 61 is provided with a first guide surface 62 at the lower end; the vertical bar 7 is provided with a second guide surface 72 at the upper end; the upper end of the vertical bar 7 enters the corresponding vertical groove 61 under the guidance of the first guide surface 62 and the second guide surface 72 .

[0052] After the material inside the mold assembly 3 is solidified, the chain 25 will drive the mold assembly 3 to transmit from top to bottom. During the downward movement of the mold assembly 3 and the corresponding counterweight 6 as the chain 25 moves, the counterweight 6 will move close to the vertical bar 7. The vertical bar 7 enters the corresponding vertical groove 61 after the counterweight 6 moves downward. In order to make the vertical bar 7 enter the vertical groove 61 more smoothly, a first guide surface 62 is provided at the lower end of the vertical groove 61, and the vertical groove 61 is matched with the second guide surface 72 at the upper end of the vertical bar 7, so that the vertical bar 7 can smoothly enter the vertical groove 61. The vertical bar 7 and the vertical groove 61 are adapted to each other, so that the counterweight 6 cannot swing, and during the injection molding process of one of the mold assemblies 3, the counterweight 6 on the vertical bar 7 stops moving. After the counterweight 6 is restricted by the vertical bar 7 and cannot swing, the mold assembly 3 on the corresponding connecting rod 4 cannot swing. In this way, it is more convenient for the staff to take out the formed slippers from the mold assembly 3 when the mold assembly 3 is stable, which greatly improves the convenience of taking out the formed slippers.

[0053] During the process of removing the slippers from the mold assembly 3, the mold assembly 3 will be observed and cleaned. If the mold assembly 3 is found to be damaged and cannot be used, the two L-shaped bars 43 are directly pinched away from the end of the chain 25. After being pinched, the two L-shaped bars 43 overcome the corresponding springs 44 and move toward each other. The end of the L-shaped bar 43 close to the chain 25 will move out of the corresponding slot 32 and retract into the corresponding L-shaped slot 42, so that the connecting rod 4 and the mold sleeve 31 are unlocked, and then the mold is rotated. The die sleeve 31 is inserted into the outer wall of the connecting rod 4, so that the slot 32 on the inner wall of the die sleeve 31 is staggered with the end of the L-shaped slot 42 close to the chain 25. After the end of the L-shaped strip 43 away from the chain 25 is loosened, the die sleeve 31 together with the die assembly 3 is directly removed from the connecting rod 4, and then a new die sleeve 31 and the die assembly 3 are sleeved on the outer wall of the connecting rod 4. When the die sleeve 31 is installed on the outer wall of the connecting rod 4, the die sleeve 31 will squeeze the third guide surface 431, so that the end of the L-shaped strip 43 close to the chain 25 is affected. The end of the L-shaped bar 43 is pushed into the slot 32 by the elastic force of the corresponding spring 44 to lock the mold sleeve 31 and the connecting rod 4. In order to make the slot 32 and the L-shaped slot 42 closer to the end of the chain 25 more accurately align, a convex ring can be fixedly connected to the outer wall of the connecting rod 4 to position the mold sleeve 31. After the mold sleeve 31 and the connecting rod 4 are locked, the new mold assembly 3 is covered and put into use. Since the counterweight block 6 is clamped by the corresponding vertical bar 7, the mold assembly 3 can be stably disassembled and replaced without shaking the connecting rod 4, which makes replacement more convenient. In addition, the clamping connection between the L-shaped bar 43 and the slot 32 makes the replacement of the mold assembly 3 more convenient and quick, thereby reducing the waiting time of the injection molding equipment as much as possible and ensuring production capacity.
