The processing steps of rubber products include raw material preparation, mixing, molding and vulcanization. In this processing step, the molding of rubber products is inseparable from the injection molding machine. The injection molding machine can quickly inject the mixed rubber material into the mold, and accurately control the temperature, pressure and injection speed, etc., which can ensure that the dimensional accuracy, density uniformity and surface quality of the rubber products can reach a high level, reducing product defects and scrap rates; in the injection molding process of the existing injection molding machine, the characteristics of rubber products determine that its processing process needs to be precisely controlled. Rubber materials of different models and formulas may have different fluidity, shrinkage and vulcanization characteristics. Therefore, after completing the injection molding of a model, it is necessary to wait for the model to cool naturally before the next injection molding operation; when the injection molding machine completes the injection molding of a model, it must wait for the current model to complete the injection molding, pressure holding, cooling and other processes and take out the product before the next injection molding operation can be carried out.

As the injection head 11 moves downward, its end portion is kept overlapping with the model 14, and then the feed trough 12 inputs the rubber product inside it into the inside of the frame 1, so that the injection head 11 injects the rubber product inside it into the inside of the model 14 to ensure the processing quality of the rubber product, and the first servo motor 25 drives the support table 24 and the rotating table 21 to rotate along the frame 1, and then the rotating table 21 rotates to drive the placement groove 22, the placement frame 23 and the model 14 to rotate synchronously. At this time, the model 14 moves along the bottom of the injection head 11 under the rotation of the rotating table 21, and the model 14 after injection molding is completed is away from the bottom of the injection head 11, and one of the models 14 moves closer to the bottom of the injection head 11, so that several models 14 and the injection head 11 complete the injection molding and cooling operations on one side, so that the model 14 moves along the bottom of the injection head 11 to complete the rotation operation.

[0044] When the injection head 11 performs continuous injection molding on the model 14, and the model 14 moves along the bottom of the injection head 11 to complete the rotation operation, the two centering columns 38 are driven to rotate simultaneously by the rotation of the stabilizing table 33, and then the two centering columns 38 rotate to pull the two displacement plates 36 to move toward or relative to each other. At this time, the two displacement plates 36 rotate along the outside of the two connecting columns 37 and pull the two connecting columns 37 to move relative to or toward each other, and the two connecting columns 37 move toward each other to pull the two bottom plates 34 to move toward each other synchronously, and the bottom plate 34 drives the directional sleeve 301 to move simultaneously during the movement, and then the inside of the directional sleeve 301 moves along the outside of the directional rod 39. At this time, the directional sleeve 301 is guided and moved in the placement frame 23 to ensure stable contact between the limiting frame 35 and the model 14, so that the two bottom plates 34 move to drive the two limiting frames 35 to approach the outside of the model 14, so that part of the limiting frame 35 is pre-fitted with the outside of the model 14, and then the injection head 11 moves downward to contact the model 14, and then the other part of the limiting frame 35 contacts the outside of the injection head 11, so that the injection head 11 can still contact the model 14 when the model 14 is restricted, so that the injection head 11 and the model 14 are accurately contacted, ensuring stable injection between the injection head 11 and the model 14.

[0046] When it is necessary to provide drive to the limiting frame 35, the second servo motor 41 drives the first gear 43 to move in a circular motion along the bottom end of the supporting disc frame 42, and then the first gear 43 rotates and engages with the second gear 44. At this time, the second gear 44 rotates to drive the rotating column 32 to rotate along the rotating table 21, the support table 24 and the centering sleeve 302. At this time, the arc plate 46 is pushed to drive the fixed arc block 45 to move synchronously, and then the fixed arc block 45 moves to drive the limiting ring 47 to rotate along the outside of the rotating table 21 and the support table 24. At this time, the arc plate 46 moves along the outside of the rotating table 21, the placement frame 23 and the placement groove 22, which is used to open or temporarily close the placement groove 22, so that the arc plate 46 can maintain a reliable lock between the model 14 and the limiting frame 35 after moving, ensuring that the model 14 will not be displaced due to loosening during the injection molding process, which helps to maintain stable injection between the injection head 11 and the model 14.

[0047] refer to Figure 8-Figure 11 As shown, the side insertion assembly 5 includes a side ear plate 56 fixedly connected to the outside of the injection head 11 and an extrusion plate 55 installed on the side of the limiting frame 35 close to the injection head 11, and the extrusion plate 55 is used to maintain stable contact between the injection head 11 and the limiting frame 35, and a moving cavity 52 is opened on one side of the limiting frame 35, and a moving cone column 51 is slidably connected inside the moving cavity 52, and one end of the moving cone column 51 is fixedly connected to one side of the extrusion plate 55, one side of the side ear plate 56 is set as an inclined structure, and the side of the moving cone column 51 corresponding to the side ear plate 56 is set as an inclined structure, and the slope between the moving cone column 51 and the side ear plate 56 is matched; the outside of the moving cone column 51 is also sleeved with a contact ring 53, and a spring 54 is commonly connected between the moving cavity 52 and the contact ring 53, and the spring 54 is sleeved on the outside of the moving cone column 51, and the spring 54 is used to push the moving cone column 51 to move and reset;

[0048] When the limiting frame 35 limits the model 14 and the injection head 11 approaches the model 14, the side ear plate 56 is driven to move downward synchronously by the downward movement of the injection head 11, and then the inclined part of the side ear plate 56 contacts the inclined part of the moving cone column 51 and generates a relative extrusion force, which is used to push the moving cone column 51 to move along the inside of the moving cavity 52 in the direction of the force. At this time, the moving cone column 51 moves to push the extrusion plate 55 along one side of the limiting frame 35 to approach the outside of the injection head 11, and the moving cone column 51 moves inside the moving cavity 52 to drive the contact plate 55 to move.

[0049] Working principle:

[0050] When in use;

[0051] First, the concentric component 4 drives the rotating column 32 to rotate simultaneously, and then the rotating column 32 rotates to drive the two centering columns 38 to rotate simultaneously, and then the two centering columns 38 rotate to pull the two displacement plates 36 to move toward or relative to each other. At this time, the two displacement plates 36 rotate along the outside of the two connecting columns 37 and pull the two connecting columns 37 to move relative to or toward each other, so that the two connecting columns 37 move toward each other and pull the two bottom plates 34 to move toward each other synchronously, so that the movement of the two bottom plates 34 drives the two limiting frames 35 to approach the outside of the model 14, so that part of the limiting frames 35 is pre-fitted with the outside of the model 14.

[0052] After the model 14 is restricted on the placement rack 23 by the limiting rack 35, the first servo motor 25 drives the support table 24 and the rotating table 21 to rotate along the frame 1, and then the rotating table 21 rotates to drive the placement slot 22, the placement rack 23 and the model 14 to rotate synchronously. At this time, the model 14 moves along the bottom of the injection head 11 under the rotation of the rotating table 21, and the model 14 after injection molding is completed is away from the bottom of the injection head 11, and one of the models 14 moves closer to the bottom of the injection head 11, so that several models 14 and the injection head 11 complete the injection molding on one side and cooling on the other side, so that the model 14 moves along the bottom of the injection head 11 to complete the rotation operation.

[0053] The model 14 is driven to be located below the injection head 11 by the rotation of the rotating table 21. At this time, the telescopic cylinder 13 is telescopic to push the injection head 11 to move downward along one side of the frame 1. The downward movement of the injection head 11 drives the side ear plate 56 to move downward synchronously. Then, the inclined part of the side ear plate 56 contacts the inclined part of the moving cone column 51 and generates a relative extrusion force, which is used to push the moving cone column 51 to move along the inside of the moving cavity 52 in the direction of the force. At this time, the moving cone column 51 moves and pushes the extrusion plate 55 along one side of the limiting frame 35 to approach the outside of the injection head 11, and the moving cone column 51 moves inside the moving cavity 52, driving the resistance ring 53 to move synchronously. That is, the resistance ring 53 pushes the spring 54 during movement, so that the spring 54 is squeezed inside the resistance ring 53 and the moving cavity 52, and after the inclined end of the side ear plate 56 contacts the inclined end of the moving cone column 51, the side ear plate 56 maintains contact with the limiting frame 35, so that the extrusion plate 55 maintains resistance to the outside of the injection head 11 on one side of the limiting frame 35, and as the injection head 11 moves downward, its end is kept overlapped with the model 14, and then the feed trough 12 inputs the rubber product inside it into the interior of the frame 1, so that the injection head 11 injects the rubber product inside it into the interior of the model 14, thereby ensuring the processing quality of the rubber product.

[0054] The above only describes certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, a person skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
