[0002] During production and processing, laryngoscopes are usually made of plastic and formed in one piece through an injection molding process. A lens module is embedded inside. However, when in use, the outer shell is relatively hard and can easily cause scratches when inserted into the patient's throat. Therefore, a secondary injection molding is usually performed on the end to form a soft rubber outer layer on the end to reduce damage to the patient.

[0003] In the existing secondary injection molding process, a split injection mold is usually used to clamp the already formed laryngoscope handle, and then soft glue is injected into the mold. After the soft glue is formed, the mold is opened so that the soft glue adheres to the end of the laryngoscope. However, in actual production and processing, the laryngoscope needs to be placed in the mold manually or by a robotic arm during the processing, and then taken out after the processing is completed. The whole process requires multiple steps, and the processing is discontinuous, resulting in low overall efficiency and high equipment cost and control cost.

[0034] See attached Figure 1 -Attached Fig.12 As shown, a laryngoscope plastic injection molding process comprises the following steps: Step 1: Use the laryngoscope plastic handle as a process handle for positioning and loading; Step 2: Synchronously injecting the ends of multiple groups of laryngoscopes to form a soft rubber outer layer; Step 3: After the soft rubber layer cools down, batch unloading is completed automatically.

[0035] Working principle: When in use, multiple laryngoscopes are placed in the loading slide 22, with the handles of the laryngoscope facing upward and the functional ends facing downward, and the functional ends are positioned using the positioning clamp 23 so that the ends face horizontally backward. At this time, they slide downward along the "S"-shaped loading slide 22, so that the handles of the laryngoscopes move to the bottom of the loading slide 22 and are blocked by two sets of flip blocking rods 26; During the initial start-up, multiple groups of laryngoscope handles are manually pushed forward so that the laryngoscope handles enter the circulating feed conveyor 32, and the laryngoscope handles are clamped by two opposite groups of clamping blocks 323, and the number of laryngoscope handles pushed in is the same as the number of mold slots inside the steel mold 342; Then, the opening and closing cylinder 345 is started, so that the opening and closing cylinder 345 pushes the steel molds 342 on both sides to move toward the middle, and at this time, multiple laryngoscope handles enter the mold groove 343. At this time, the lifting cylinder 314 is started, so that it drives the electric heating bin 312 to move upward, so that the injection needle on the top of the electric heating bin 312 is inserted into the injection hole 344, and then the screw extruder 311 is started to squeeze the soft rubber material into the electric heating bin 312, and at the same time enters the mold groove 343 through the injection needle, and then the lifting cylinder 314 drives the electric heating bin 312 to move downward; In this process, the cooling liquid is injected into the interlayer of the steel mold 342 through the circulating cooler 331 to quickly cool the soft glue inside the mold groove 343, so that the soft glue adheres to the outer surface of the functional end of the laryngoscope to form a soft glue outer layer; Then, the servo motor 355 is started to drive the driving screw 354 to rotate, so that the driving traction member 356 moves along the guide rail 353 to the end away from the feeding slideway 22. At this time, the driving traction member 356 drives the steel mold 342 to move along the positioning groove 12, so that the laryngoscope handle moves to the end of the circulating feeding conveyor 32; Then, the two groups of opening and closing cylinders 345 drive the two groups of steel molds 342 to move to both sides. At this time, the steel mold 342, under the action of the memory spring 348, first slides a short distance outward along the top shaft 346 and contacts the retaining ring 347. At this time, the top shaft 346 does not move and keeps contacting the injection molded part, so that the steel mold 342 is separated from the injection molded part. Then, the opening and closing cylinders 345 continue to move. At this time, under the action of the retaining ring 347, the steel mold 342 drives the top shaft 346 to move outward synchronously, so that the memory spring 348 is compressed, so that the top shaft 346 is used as a stripping ejector pin to separate the steel mold 342 from the injection molded part. At this time, the laryngoscope that has been completed by injection molding is suspended at the end of the circulating chain 322. At the same time, in the above process, as the steel mold 342 clamps the laryngoscope and moves backward, the laryngoscope handle drives the clamping block 323 to move, and the entire circulating chain 322 moves. At this time, the clamping block 323 at the front end of the circulating chain 322 continues to gather and move from both sides to the middle, and the clamping block 323 smoothly moves to the outer surface of the laryngoscope at the end of the loading slide 22 through the smooth surface, and then the circulating chain 322 continues to move, and the clamping block 323 removes the laryngoscope between the two groups of flip baffles 26 through the sharp protrusion, so that the position of the laryngoscope handle is stuck inside the arc groove, and moves forward with the circulating chain 322. At the same time, the laryngoscope on the loading slide 22 slides forward under the action of gravity, so that the front end of the laryngoscope fills the position and enters between the two groups of flip baffles 26. It should be noted that the distance that the steel mold 342 moves forward is the same as the length of the steel mold 342, so that the circulating chain 322 removes the same number of laryngoscopes from between the two groups of flip baffles 26 during the process of following the movement of the steel mold 342; Then the servo motor 355 is controlled to reverse, driving the expanded steel mold 342 to move in the opposite direction to the initial point, at which time the opening and closing cylinder 345 drives the two groups of steel molds 342 to clamp the surfaces of the newly added laryngoscopes again, and then the injection molding unit 31 is started again for injection molding, and then the steel mold 342 moves forward again, and at this time moves through the circulating chain 322, so that the first group of laryngoscopes that have completed injection molding are separated from the circulating chain 322 and fall downward from the end thereof for unloading, while the second group of laryngoscopes that have completed injection molding move to the unloading area to wait for unloading; As a result, in the subsequent processing, there is no need to use other loading mechanisms. The laryngoscope will automatically slide to the position of the flip baffle 26 under the action of gravity to wait for loading, and the circulating feed conveyor 32 will automatically clamp the laryngoscope for loading during the movement of the steel mold 342, and the circulating chain 322 will automatically unload the material when the steel mold 342 moves for the second time, thereby achieving a high degree of automation and continuous operation in the entire processing process, without the need for complex driving components to cooperate with each other, and lower equipment cost and control cost.
