DETAILED DESCRIPTION

[0028] Example 1

[0029] This embodiment is intended to help solve the problem that during the injection molding process, the main body of the injection molding machine is usually moved. However, when the injection molding bucket is large, the movement of the injection molding machine will be disconnected from the injection molding bucket, resulting in a material transport fault in the injection molding machine, which does not meet the actual processing needs. Please refer to Figure 1-Figure 7A screw push mechanism of an injection molding machine comprises an injection mold placement frame 1, a mold push mechanism is installed outside the injection mold placement frame 1, an outer wall of the injection mold placement frame 1 is fixedly connected with an injection molding machine slide rail 5, an outer wall of the injection molding machine slide rail 5 is installed with a conveying push mechanism, the conveying push mechanism comprises a support frame 22, an outer wall of the support frame 22 is provided with a heating push mechanism, the heating push mechanism comprises an injection molding machine heating cavity 8, the injection molding machine heating cavity 8 is connected with a first fixed frame 11 through a plastic raw material conveying pipe 10, the inner wall of the first fixed frame 11 is provided with a conveying mechanism, and the outer wall of the first fixed frame 11 is fixedly connected with a first sliding frame 14;

[0030] An adjusting mechanism is arranged on the inner wall of the first sliding frame 14, and the adjusting mechanism comprises a first return spring 17. A supporting frame 22 for supporting an injection molding feed hopper 27 is fixedly connected to the outer wall of the injection molding machine slide rail 5. A first inclined surface mechanism for conveying the injection molding feed hopper 27 is fixedly connected to the outer wall of the first return spring 17. A second inclined surface 29 is provided on the inner wall of the first sliding frame 14. The first inclined surface mechanism comprises a soft guide track 18, and specifically, one end of the soft guide track 18 is fixedly connected to the first return spring 17. The outer wall of the soft guide track 18 is slidably connected to a guiding mechanism for guiding the injection molding feed hopper 27. The guiding mechanism comprises a second sliding frame 31, and the second sliding frame 31 is fixedly connected to the outer wall of the injection molding feed hopper 27. An injection molding feed port 26 is provided on the outer wall of the injection molding feed hopper 27. An injection molding discharge port 36 is provided on the outer wall of the first fixed frame 11.

[0031] The mold pushing mechanism includes a first electric telescopic rod 2, an injection molding upper mold 3 and an injection molding lower mold 4. The first electric telescopic rod 2 is installed on the outer wall of the injection mold placement frame 1. The output end of the first electric telescopic rod 2 is fixedly connected to the injection molding upper mold 3 for docking with the injection molding lower mold 4. The injection molding lower mold 4 is detachably arranged on the outer wall of the injection mold placement frame 1.

[0032] The conveying and pushing mechanism also includes a second electric telescopic rod 6, which is installed on the outer wall of the injection molding machine slide rail 5, and the output end of the second electric telescopic rod 6 is fixedly connected to a support frame 22 that slides with the inner wall of the injection molding machine slide rail 5;

[0033] The heating and pushing mechanism also includes an injection molding machine heating cavity 8, and the injection molding machine heating cavity 8 is fixedly connected to the output end of the injection molding machine heating cavity 8;

[0034] The conveying mechanism includes a transmission motor 13 and an injection molding material conveying screw 12. The transmission motor 13 is installed on the outer wall of the first fixed frame 11. The output end of the transmission motor 13 is fixedly connected to the injection molding material conveying screw 12 which is rotatably connected to the inner wall of the first fixed frame 11. After the injection molding material conveying screw 12 rotates, it starts to convey the injection molding material into the plastic material conveying pipe 10, and as the plastic material conveying pipe 10 enters the heating cavity 8 of the injection molding machine for heating, the injection molding machine heating cavity 8 is heated and then the injection molding machine injection head 9 is used for injection molding. The injection molding machine injection head 9 injects the injection molding material into the mold composed of the injection molding upper mold 3 and the injection molding lower mold 4 to complete the injection molding.

[0035] The soft guide crawler 18 is configured as a soft crawler strip, and the other end of the soft guide crawler 18 is fixedly connected to the inner wall of the first sliding frame 14. Figure 4 The middle soft guide crawler 18 is fixedly assembled at the bottom of the first fixed frame 11 and is adjacent to the discharge port 36 so that the soft guide crawler 18 can feed materials to the discharge port 36. The outer wall of the soft guide crawler 18 slides in the space formed between the first guide rod 32 and the second guide rod 33 in sliding contact, which will cause the injection molding feed hopper 27 to move relative to the surface of the soft guide crawler 18 through the first guide rod 32 and the second guide rod 33. In the process of relative position movement of the injection molding feed hopper 27, the injection molding feed hopper 27 will continuously change the shape of the soft guide crawler 18 through the sliding position of the soft guide crawler 18 by the first guide rod 32 and the second guide rod 33, so that the right side of the soft guide crawler 18 always maintains an inclined state to facilitate feeding materials to the discharge port 36. Therefore, no matter where the relative position of the injection molding feed hopper 27 is, the materials falling from the injection molding feed hopper 27 will still enter the injection molding discharge port 36 through the inclined soft guide crawler 18 for continuous transportation;

[0036] The first inclined surface mechanism also includes a support rod 19. The inner wall of the soft guide crawler 18 is provided with a plurality of support rods 19 for supporting. In order to prevent the soft guide crawler 18 from being deformed by the raw material, the inner wall of the soft guide crawler 18 is provided with a plurality of evenly distributed support rods 19, which provide good support force for the soft guide crawler 18 and prevent the deformation of both sides of the soft guide crawler 18 from causing the raw material to fall.

[0037] The guide mechanism further includes a first guide rod 32, a second guide rod 33, a second return spring 34, a fixing plate 35 and a roller 37. The first guide rod 32 is rotatably connected to the outer wall of the second sliding frame 31. The second sliding frame 31 is provided with two. The space formed between the first guide rod 32 and the second guide rod 33 is slidably connected to the outer wall of the soft guide crawler 18.

[0038] The inner wall of the second sliding frame 31 is slidably connected with a fixed plate 35, the outer wall of the fixed plate 35 is fixedly connected with a second return spring 34, one end of the second return spring 34 is fixedly connected to the outer wall of the second sliding frame 31, both ends of the second guide rod 33 are connected to the inner wall of the fixed plate 35, the outer wall of the fixed plate 35 is fixedly connected with the second return spring 34, the end of the second guide rod 33 of the fixed plate is interlaced with the end of the fixed plate 35, and the outer wall of the second guide rod 33 is rotatably sleeved with a roller 37.

[0039] In this embodiment: before injection molding, the first electric telescopic rod 2 is first started, and after the output end of the first electric telescopic rod 2 is extended, the injection molding upper mold 3 and the injection molding lower mold 4 are docked. At this time, the injection plastic is added into the injection molding feed hopper 27 so that it passes through the through groove 36 and enters the first fixed frame 11. At this time, the transmission motor 13 is started. After the transmission motor 13 is started, the injection molding material conveying screw 12 at its output end is rotated. After the injection molding material conveying screw 12 rotates, the injection molding material begins to be conveyed into the plastic material conveying pipe 10, and as the plastic material conveying pipe 10 enters the heating cavity 8 of the injection molding machine for heating, the heating cavity 8 of the injection molding machine is heated and then injection molding is performed through the injection molding head 9 of the injection molding machine. The injection molding head 9 of the injection molding machine injects the injection molding material into the mold composed of the injection molding upper mold 3 and the injection molding lower mold 4 to complete the injection molding;

[0040] First, the second electric telescopic rod 6 is started, and the second electric telescopic rod 6 slides backward along the inner wall of the injection molding machine slide rail 5 with the injection molding machine sliding base 7 at the output end, and the injection molding machine injection head 9 will gradually withdraw from the injection molding lower mold 4. As the injection molding machine sliding base 7 moves, the first sliding frame 14 follows the movement, and the first sliding frame 14 moves synchronously with the soft guide crawler 18 on its inner wall. At this time, as the soft guide crawler 18 at the inclined angle moves, it will slide in the space formed between the first guide rod 32 and the second guide rod 33 that the outer wall of the soft guide crawler 18 slides in contact with, which will cause the injection molding feed hopper 2 The first guide rod 32 and the second guide rod 33 move relative to each other along the surface of the soft guide track 18, and during the relative position movement of the injection molding feed hopper 27, the injection molding feed hopper 27 continuously changes the shape of the soft guide track 18 through the sliding position of the soft guide track 18 by the first guide rod 32 and the second guide rod 33, so that a part of the soft guide track 18 always maintains an inclined state. Therefore, no matter where the relative position of the injection molding feed hopper 27 is, the material falling from the injection molding feed hopper 27 will still enter the injection molding discharge port 36 through the inclined soft guide track 18 for continuous transportation;

[0041] When the second electric telescopic rod 6 brings the injection molding machine sliding base 7 at the output end forward along the injection molding machine slide rail 5, the injection molding feed hopper 27 will slide along the outer wall of the soft guide track 18 through the space formed between the first guide rod 32 and the second guide rod 33. During the sliding process, a part of the soft guide track 18 still remains in an inclined state, ensuring that the injection molding feed hopper 27 can still continue to transport materials to the injection molding discharge port 36, until the relative position of the injection molding feed hopper 27 is close to the second inclined surface 29, and the reset is completed;

[0042] In order to prevent the soft guide crawler 18 from being deformed by the raw material, a plurality of evenly distributed support rods 19 are provided on the inner wall of the soft guide crawler 18 to provide good support force for the soft guide crawler 18 and prevent the raw material from falling due to deformation of both sides of the soft guide crawler 18;

[0043] When the injection molding feed hopper 27 and the sliding guide of the soft guide crawler 18 are in contact, it is only necessary to pull the fixing plate 35 to both sides at the same time, so that the fixing plate 35 stretches the second spring 34 so as to slide and displace inside the second sliding frame 31, so that the two ends of the second guide rod 33 are disengaged from the end of the fixing plate 35, and the second guide rod 33 is removed. The roller 37 that is rotatably connected and sleeved on the outer wall of the second guide rod 33 can reduce the friction when it contacts the soft guide crawler 18.

[0044] The invention solves the problem that during the injection molding process, when the injection molding part of the injection molding machine moves, the lower hopper is usually large in size and is not convenient to move synchronously with the injection molding end of the injection molding machine.

[0045] Example 2

[0046] This embodiment is intended to promote the problem that the soft guide track 18 is easily deformed and stretched due to its soft characteristics after long-term use. Since the first inclined surface mechanism is heavy, this embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 7 The outer wall of the bolt 15 is threadedly connected to the inner wall of the first sliding frame 14, and the end of the bolt 15 is rotatably connected to the moving plate 16. The outer wall of the moving plate 16 is fixedly connected to the outer wall of the soft guide track 18 through the first return spring 17. After the bolt 15 is screwed, due to the threaded connection relationship between it and the first sliding frame 14, it is prompted to move out of the first sliding frame 14 with the moving plate 16 rotatably connected at its end. At this time, the moving plate 16 stretches the first return spring 17 outward, causing the first return spring 17 to deform and increase the tension of the soft guide track 18 at the other end thereof, thereby adjusting the length of the soft guide track 18.

[0047] In this embodiment: since the first inclined surface mechanism is heavy, the soft guide track 18 is easily deformed and stretched due to its soft characteristics after long-term use;

[0048] Therefore, after the soft guide crawler 18 is deformed, the bolt 15 can be screwed. After the bolt 15 is screwed, the threaded connection relationship between the bolt 15 and the first sliding frame 14 causes the bolt 15 to move outward of the first sliding frame 14 with the movable plate 16 connected to the end thereof. At this time, the movable plate 16 stretches the first return spring 17 outward, causing the first return spring 17 to deform and increase the tension of the soft guide crawler 18 at the other end thereof, thereby adjusting the length of the soft guide crawler 18.

[0049] Since the soft guide crawler 18 is a consumable part, and when a new soft guide crawler 18 is replaced, the new soft guide crawler 18 is in a taut state after installation, and when the first inclined plane mechanism climbs along the soft guide crawler 18, the soft guide crawler 18 is in a taut state, which may cause the soft guide crawler 18 to break directly. The soft guide crawler 18 can also be loosened by rotating the bolt 15.

[0050] The problem that the soft guide crawler 18 is easily deformed and stretched due to its soft characteristics after long-term use, resulting in the length of the soft guide crawler 18 being lengthened is solved.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
