Description

Technical Field

[0001] The present invention relates to the technical field of injection molding, and in particular to an injection molding device for recycling battery boxes. Background Art

[0002] Injection molding is a method for producing and shaping industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. The injection molding machine is the main molding equipment that uses plastic molding molds to make thermoplastic plastics or thermosetting materials into various shapes of plastic products. Injection molding is achieved through injection molding machines and molds. There are exhaust holes on the injection mold. During the injection molding process of plastic battery boxes, the melted plastic is injected into the mold, and the air in the mold cavity is squeezed out at the same time. When the mold cavity is filled with plastic, the plastic conveying should be stopped in time to avoid the plastic from overflowing through the pores. However, the timing of stopping the plastic conveying is difficult to control. Stopping in advance will cause defects in the injection molded product, and delaying stopping will cause plastic to invade the pores. For this reason, the present invention provides an injection molding device for recycling battery boxes. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention uses the exhaust cavity to discharge the air in the mold cavity during injection molding. The mold cavity is filled with plastic. If the injection molding continues, plastic will overflow from the stop block, and then automatically trigger the stop block to move to block the exhaust cavity.

The main pressure ring plate pushes the stop block by rotating, and the stop block blocks the exhaust channel of the exhaust cavity after moving. The timing of the main pressure ring plate rotation is when the integration tool is triggered. The integration tool will automatically trigger when it detects that there is continuous overflow of plastic in the stop block. In this way, at the end of the injection molding work, there will be continuous overflow of plastic, and the stop block will automatically move to block the plastic overflow path to ensure that the injection molding work is successfully completed.

[0040] The deceleration cylinder 35 includes a piston column 42 with one end fixed on the tail T-plate 34, a cylinder barrel 43 with a sliding sleeve on the other end of the piston column 42, and a valve spring 44 fixed to the outside of the cylinder barrel 43. The valve spring 44 is provided with a disk body to cover the end port of the cylinder barrel 43 away from the piston column 42, and a slow reflux air hole is opened in the middle of the disk body. The cylinder barrel 43 is fixed on the integrated frame 37.

[0041] The interception group 31 includes a U-shaped plate 49 with an intercepting limit block 21 at one end, a release gear 48 meshing and transmission connected to a row of teeth set on the U-shaped plate 49, a traverse shaft 47 fixedly connected to the release gear 48 at one end, a long worm 45 for vertical transmission at the other end of the traverse shaft 47, and a tail plate frame 46 fixed on the device box 10. The long worm 45 and the traverse shaft 47 are respectively movably sleeved in two through holes opened in the tail plate frame 46. One end of the long worm 45 is meshing and transmission connected with the gear fixed on the traverse shaft 47 by setting spiral teeth, and the other end of the long worm 45 is meshing and transmission connected with a row of teeth set on the tail T-plate 34 through a fixed gear. The other end of the U-shaped plate 49 slides through the square hole opened in the tail plate frame 46.

[0042] The water delivery device 14 includes an inlet square tube 53 with one end extending to the outside of the device box 10, a water blocking block 50 slidably inserted into the other end of the inlet square tube 53, an L-shaped baffle 51 fixed on one side of the water blocking block 50 for secondary interception of the limiting block 21, a pullback spring 52 connected between the L-shaped baffle 51 and the inlet square tube 53, an L-shaped square tube 54 fixedly connected to one side of the inlet square tube 53, and a movable square tube 55 with one end slidingly inserted into the L-shaped square tube 54. The other end of the movable square tube 55 is fixed to the flow-stop block 11. A V-shaped column cavity 56 is provided in the flow-stop block 11. One end of the V-shaped column cavity 56 is connected to the guide hole in the flow-stop block 11, and the other end is connected to the movable square tube 55. The water flow introduced into the square tube 53 hits the water blocking block 50 and then flows into the L-shaped square tube 54.

[0043] After the movable mold 5 and the fixed mold 2 are butt-jointed and sealed, molten plastic is injected into the injection molding chamber between the movable mold 5 and the fixed mold 2. The injected plastic will squeeze out the air in the injection molding chamber, and the air is discharged through the exhaust cavity 8. During the discharge process, the air is injected into the device box 10 through the guide hole of the stop block 11, and then discharged through the air separation hole 17. Some air is also discharged at the collecting tool 16, which in turn drives the collecting tool 16. The collecting tool 16 collects air power and then supplies power to the main pressing tool 13. The main pressing tool 13 is full of power, and the plastic is filled in the injection molding chamber. After the plastic cavity is formed, plastic is continuously injected, and plastic will overflow through the exhaust cavity hole 8, and the overflowed plastic is discharged through the guide hole of the stop block 11. During the overflow process, the plastic gradually hardens itself, and the previously discharged air flow will not drive the J-shaped plate 33 to swing. The hard plastic discharged through the guide hole of the stop block 11 will hit the J-shaped plate 33, and the swing of the J-shaped plate 33 will trigger the first interception and release of the subsequent limiting block 21. The main pressure ring plate 20 rotates after losing the interception and is then intercepted for the second time. However, the main pressure ring plate 20 completes the initial rotation, and the stop block 11 is moved out from the arc groove of the main pressure ring plate 20, and the moved stop block 11 blocks the exhaust cavity hole 8, so that the plastic in the exhaust cavity hole 8 no longer overflows, and the L-shaped baffle 51 intercepts the limiting block 21 for the second time. After the injection molding work is completed, water is injected into the stop block 11 to flush out the plastic in the guide hole, ensuring that the guide hole can be smoothly exhausted during the next injection molding work. While injecting water, the secondary interception of the limiting block 21 will be stopped, so that the limiting block 21 is released for the second time, and the main pressure ring plate 20 will continue to complete the subsequent rotation until it is stopped by the U-shaped plate 4 9 is intercepted again. At this time, the main pressure ring plate 20 completes a circle of rotation. The above is a working cycle in the stopper 9. The water injection work of the stop block 11 is completed before the main pressure ring plate 20 completes a full circle of rotation. When the limiting block 21 is intercepted again by the U-shaped plate 49, the stop block 11 is reset under the push of the spring mechanism 12 of the prior art, and one end of the stop block 11 is re-stuck in the arc groove of the main pressure ring plate 20. After the stop block 11 is reset, the guide hole on the stop block 11 is connected to the exhaust cavity hole 8 again, so that the next injection exhaust can be carried out.

[0044] The air is discharged through the air distribution flat pipe 28, which drives the blade 27 to swing during the discharge process, and then the wind shaft 25 continues to rotate to drive the worm 29, and then the ring gear 30 drives the center shaft 22 to rotate. Under the restriction of the one-way bearing 24, the center shaft 22 can only rotate in one direction, causing the mainspring 19 to contract and store power.

[0045] The principle of the first interception release caused by the swing of the J-shaped plate 33 is as follows: the swing of the J-shaped plate 33 drives the pressing shaft 40 to rotate, and then the head rack 41 is transmitted through the travel gear 39. The head rack 41 drives the wave spring piece 36 during movement, and then the tail T-plate 34 moves with it to drive the long worm 45. Then the traverse shaft 47 drives the release gear 48 to rotate, and the U-shaped plate 49 moves away from the limit block 21, thus releasing the limit block 21 for the first time.

[0046] The principle of water injection in the flow-stop block 11 is as follows: the square tube 53 is introduced and connected to the water supply mechanism in the prior art, and the water flow in the square tube 53 is injected into the L-shaped square tube 54. During the process, the water flow first impacts the water-blocking block 50. After the water-blocking block 50 moves, the interface between the square tube 53 and the L-shaped square tube 54 is exposed, so that the water flow is injected into the L-shaped square tube 54, and then injected into the V-shaped column cavity 56 through the movable square tube 55. Next, the water flow is discharged from the guide hole of the flow-stop block 11, and the guide hole of the flow-stop block 11 is flushed during the discharge process. When the water-blocking block 50 is impacted, it drives the L-shaped baffle 51 to move synchronously. After the L-shaped baffle 51 moves, it no longer intercepts the limiting block 21, thereby releasing the limiting block 21 for the second time.

[0047] When the next injection molding cycle starts, there will be blocked plastic in the exhaust cavity 8, that is, the plastic retained in the exhaust cavity 8 at the end of the first injection molding. At the beginning of the next injection molding cycle, the air flow is discharged through the exhaust cavity 8, and the air flow blows the waste hard plastic. Although the waste hard plastic will hit the J-shaped plate 33 when it is discharged through the guide hole of the stop block 11, it will not cause the U-shaped plate 49 to release the limiting block 21. Because the amount of waste plastic is small, the impact time on the J-shaped plate 33 is short, and the short impact cannot ultimately affect the U-shaped plate 49 because the deceleration cylinder 35 plays a role in the process. If there is no deceleration cylinder 35, the head rack 41 and the tail T-plate 34 always move synchronously, but the existence of the deceleration cylinder 35 will limit the movement speed of the tail T-plate 34, that is, Figure 12 The head rack 41 in the middle moves quickly to the left, the wave spring piece 36 deforms and contracts, and the wave spring piece 36 pushes the tail T-plate 34. The tail T-plate 34 moves slowly to the left because the tail T-plate 34 drives the piston column 42. The process of the piston column 42 being extracted from the cylinder 43 requires external air to be replenished into the cylinder 43. The replenished air can only be carried out slowly through the fine holes on the valve spring piece 44. The negative pressure in the cylinder 43 causes the tail T-plate 34 to move slowly. Therefore, under a short impact, the head rack 41 will quickly reset after moving to the left. In this way, the tail T-plate 34 loses thrust as soon as it moves, and no continuous pressure supply is applied to the subsequent transmission. The tail T-plate 34 does not undergo sufficient translation and will not trigger the final interception and release of the U-shaped plate 49.
