[0038] To make the technical problems solved by the invention, the technical solutions and the beneficial effects clearer, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] like Figures 1-14 As shown, the present invention provides an automatic injection molding machine, including a feeding mechanism 1, an injection molding mechanism 3, and a feeding mechanism 2. The feeding mechanism 1 includes a spiral vibratory feeder 1010. Multiple rows of conveying channels 1020 are connected to the outlet of the spiral vibratory feeder 1010. Each conveying channel 1020 has a drop trough 1030 at its end. A conveying pipe 1040 is connected to the bottom of the drop trough 1030, and a straight tube 1050 is connected to the end of the conveying pipe 1040. The straight tube 1050 is positioned lower than the drop trough 1030. A movable receiving seat 1060 is provided below the straight tube 1050, and the top of the receiving seat 1060 is provided with multiple rows of receiving holes 1061; the injection molding mechanism 3 is used to perform injection molding on the product; the feeding mechanism 2 includes a moving slide rail 2010 and a picking robot arm 2020 and a unloading robot arm 2030 that move on the moving slide rail 2010. The picking robot arm 2020 is used to transport the product on the receiving hole 1061 to the injection molding mechanism 3, and the unloading robot arm 2030 is used to remove the injection molded product from the injection molding mechanism 3 and collect it.

[0040] The metal part 4 to be injection molded is poured into the spiral vibratory feeder 1010. The metal part 4 enters the conveying channel 1020 from the outlet of the spiral vibratory feeder 1010. Under the vibration of the spiral vibratory feeder 1010, the metal part 4 is conveyed to the drop trough 1030 after passing through the conveying channel 1020. The size of the drop trough 1030 is larger than the size of the metal part 4 to ensure that the metal part 4 can fall into the drop trough 1030 after leaving the conveying channel 1020. The metal part 4 falls from the drop trough 1030 into the conveying pipe 1040. Under the action of gravity, the metal part 4 falls from the conveying pipe... 1040 falls into the straight tube 1050, passes through the straight tube 1050 and lands on the receiving hole 1061. The receiving seat 1060 moves at intervals to ensure that the metal part 4 can accurately land on a different row of receiving holes 1061 each time. When all receiving holes 1061 are full, the spiral vibratory feeder 1010 stops conveying the metal part 4, and the receiving seat 1060 moves to the side closer to the injection molding mechanism 3. The material picking robot arm 2020 on the injection molding machine grabs all the metal parts 4 on the receiving seat 1060 and enters the injection molding step. After that, the receiving seat 1060 resets and the above steps are repeated. After the above steps, the feeding mechanism 1 can arrange the metal parts 4 in a certain position on the receiving seat 1060. Then, the picking robot arm 2020 is moved above the receiving seat 1060 and the metal parts 4 on the receiving hole 1061 are transported to the injection molding mechanism 3. The injection molding mechanism 3 performs injection molding on the metal parts 4. After the injection molding is completed, the unloading robot arm 2030 is moved above the injection molding mechanism 3 and the metal parts 4 on the injection molding mechanism 3 are removed and collected.

[0041] The metal part 4 is long and narrow, and a protruding annular limiting block 400 is provided on the metal part 4. Plastic is injected into the position of the annular limiting block 400 and is injection molded into a ring.

[0042] The automatic injection molding machine can arrange the metal parts 4 in a certain position on the receiving seat 1060, and use the material handling robot arm 2020 to accurately transport the metal parts 4 to the injection molding mechanism 3 for injection molding. Finally, the injection-molded metal parts 4 are collected for later use. The metal parts 4 are transported smoothly, with a high degree of automation, a large number of parts can be injected at one time, and high injection efficiency.

[0043] Feeding mechanism 1 (reference) Figures 1-5 There are four conveying channels 1020, four drop troughs 1030, four conveying pipes 1040, and four straight pipes 1050. On the receiving seat 1060, there are also four receiving holes 1061 in each row, for a total of six rows of receiving holes 1061. (Reference) Figure 4 The conveying channel 1020 includes two parallel seats 1021 and a conveying groove 1022 disposed between the two parallel seats 1021. When the metal part 4 enters the conveying channel 1020, the annular limiting block 400 abuts against the two parallel seats 1021, and the metal part 4 is placed on the conveying groove 1022, thereby further defining the shape and position of the metal part 4. The diameters of the drop trough 1030, the conveying pipe 1040, and the straight pipe 1050 are only slightly larger than the diameter of the metal part 4, ensuring that the metal part 4 will not reverse when falling.

[0044] refer to Figure 3 and Figure 4 The feeding mechanism 1 also includes a third cylinder mechanism 1080, which includes a third cylinder 1081 and a push rod 1082 connected to the third cylinder 1081. The push rod 1082 is used to push the product at the drop trough 1030. To prevent the metal part 4 at the drop trough 1030 from deviating from the drop trough 1030, the push rod 1082 pushes the metal part 4 at the drop trough 1030 in the opposite direction of the conveying channel 1020. Since there are other metal parts 4 queuing to drop behind the metal part 4, the metal part 4 at the drop trough 1030 can only fall into the drop trough 1030. The third cylinder mechanism 1080 further ensures that the metal part 4 is accurately conveyed.

[0045] Furthermore, a vibrator is connected to the conveying pipe 1040 to further push the metal part 4 inside the conveying pipe 1040 to fall.

[0046] refer to Figure 5 The feeding mechanism 1 also includes a first moving component 1090, which includes a motor 1091, a first base 1092 and a screw 1093. The motor 1091 is connected to the screw 1093, and the screw 1093 is mounted on the first base 1092. The bottom of the receiving seat 1060 is provided with a sliding block 1062, which is connected to the screw 1093. The first moving component 1090 is used to move the receiving seat 1060.

[0047] The top of the first base 1092 is provided with a guide rod 1094, and the bottom of the receiving seat 1060 is provided with a guide block 1063. The guide block 1063 moves along the guide rod 1094. The guide rod 1094 is located above the screw 1093. This structure further limits the direction of movement of the receiving seat 1060 and prevents the receiving seat 1060 from shaking when it moves.

[0048] refer to Figure 3 The feeding mechanism 1 also includes a first support frame 10100 and a second support frame 10110. The spiral vibratory feeder 1010 is mounted on the first support frame 10100, and the straight tube 1050 is mounted on the second support frame 10110. The first support frame 10100 is located on one side of the second support frame 10110. By mounting the spiral vibratory feeder 1010 and the straight tube 1050 on different support frames, it is easier to adjust their height difference, ensuring that the position of the straight tube 1050 is lower than the position of the drop trough 1030. This ensures that the metal part 4 can smoothly pass from the drop trough 1030 through the conveying pipe 1040 and into the straight tube 1050 under the action of gravity.

[0049] The second support frame 10110 is provided with a vertical second slide rail 10120, and the second slide rail 10120 is provided with a second cylinder assembly 10130. The straight tube 1050 is located at the bottom of the second cylinder assembly 10130. The height of the straight tube 1050 is adjusted by the second cylinder assembly 10130 and the second slide rail 10120 to accommodate metal parts 4 of different lengths.

[0050] The first support frame 10100 is provided with a first slide rail 10140, the first slide rail 10140 is provided with a first cylinder assembly 10150, and the drop groove 1030 is provided on the first cylinder assembly 10150. The position of the drop groove 1030 is adjusted by the first cylinder assembly 10150 and the first slide rail 10140.

[0051] The third cylinder mechanism 1080 is also located on the first support frame 10100 and can be located on the first cylinder assembly 10150. The moving direction of the push rod 1082 is perpendicular to the moving direction of the first cylinder assembly 10150.

[0052] refer to Figure 4 The feeding mechanism 1 also includes a third support rod 10160. A drop groove 1030 is provided on the third support rod 10160. The third support rod 10160 includes a support base 10161 and an adjustable base 10162 provided on the support base 10161. The support base 10161 is provided with a screw hole 10163. The bottom of the adjustable base 10162 is provided with an elongated groove 10164. The support base 10161 and the adjustable base 10162 are fixed by screws. The screws pass through the elongated groove 10164 and the screw hole 10163.

[0053] Furthermore, a product sensor 1070 is provided above the drop trough 1030 to ensure that the metal part 4 moves smoothly into the drop trough 1030. When the metal part 4 is not detected at the drop trough 1030, the spiral vibrating plate 1010 stops working.

[0054] Furthermore, a lifting seat A10170 is provided below the receiving hole 1061. Several magnetic rods A10180 are provided on the lifting seat A10170. The magnetic rods A10180 are located directly below the receiving hole 1061 and are magnetic. When the material handling robot arm 2020 grabs the metal part 4, the lifting seat A10170 rises, the magnetic rods A10180 move upward and push the metal part 4 upward. At this time, more of the metal part 4 is exposed from the receiving seat 1060, making it easier for the material handling robot arm 2020 to grab it.

[0055] Injection molding mechanism 3 (reference) Figures 6-7 The injection molding mechanism 3 includes a worktable 3010, an injection frame 3020 and a rotating platform 3030 on the worktable 3010, an injection head 3040 on the injection frame 3020, the injection head 3040 being located above the rotating platform 3030, and two injection molds 3050 symmetrically arranged radially on the rotating platform 3030. Each injection mold 3050 includes a mold base 3051 on the rotating platform 3030 and a working mold base 3052 on the mold base 3051. The working mold base 3052 and the mold base 3051 are supported by an elastic mechanism 3053. The working mold base 3052 has multiple rows and columns of product slots 3054.

[0056] Two injection molds 3050 rotate with the rotating platform 3030. The injection mold 3050 rotates to the bottom of the injection head 3040 for injection molding. After injection molding is completed, the rotating platform 3030 rotates 180° and the other injection mold 3050 rotates to the bottom of the injection head 3040 for injection molding. This process is repeated, resulting in a high degree of automation and high injection molding efficiency.

[0057] The metal part 4 is placed on the product groove 3054 of the working mold base 3052. When the injection head 3040 performs injection molding, it presses down on the working mold base 3052, and the protruding annular limiting block 400 on the metal part 4 in the product groove 3054 is exposed. The injection head 3040 performs injection molding on the position of the annular limiting block 400.

[0058] Furthermore, the injection mold 3050 is detachably fixed on the rotating platform 3030, and the injection mold 3050 is replaceable.

[0059] Furthermore, the injection molding frame 3020 includes a triangular frame 3021 and three fixed posts 3022. The three fixed posts 3022 are respectively located at the three corners of the triangular frame 3021. Two of the fixed posts 3022 are fixed to the worktable 3010 at their bottoms, and the bottom of the remaining fixed post 3022 passes through the rotating platform 3030 and is fixed to the worktable 3010. The injection head 3040 is located on the triangular frame 3021, and the injection body is externally connected to the injection head 3040. The triangular structure makes the injection more stable.

[0060] Feeding mechanism 2 reference Figures 8-14 The feeding mechanism 2 includes a movable slide rail 2010 and a picking robot arm 2020 and a unloading robot arm 2030 that move on the movable slide rail 2010. The picking robot arm 2020 is used to transport the product on the receiving hole 1061 to the injection molding mechanism 3, and the unloading robot arm 2030 is used to remove the injection molded product from the injection molding mechanism 3 and collect it.

[0061] refer to Figure 9 and Figure 10 The material handling robotic arm 2020 includes a material handling sliding frame 2021 that moves on a sliding rail 2010. The material handling sliding frame 2021 is provided with a material handling slider 2022. A lifting seat B2024 is connected to the material handling slider 2022. The lifting seat B2024 is pushed up and down by a first feeding cylinder 2023. A movable seat 2026 is provided inside the lifting seat B2024. The movable seat 2026 is pushed by a second feeding cylinder 2025. Multiple rows and columns of magnetic rods B20210 are provided inside the movable seat 2026. The bottom of the lifting seat B2024 is provided with a through hole 20211 for the magnetic rods B20210 to pass through.

[0062] The robotic arm 2020 moves along the sliding rail 2010, picking up the metal part 4 from the receiving seat 1060 and conveying it to the injection mold 3050. Specifically, when the robotic arm 2020 moves above the receiving seat 1060, the first feeding cylinder 2023 moves, driving the second feeding cylinder 2025 and the movable seat 2026 to move downwards. After moving to a certain position, the first feeding cylinder 2023 stops moving. At this time, the second feeding cylinder 2025 extends downwards, driving the movable seat 2026 to move downwards. The magnetic rod B20210 on the movable seat 2026 also moves downwards until it passes through the through hole 20211 at the bottom of the lifting seat B2024, thus exposing the robotic arm 2020. 020, and aligned with the metal part 4, the metal part 4 is attracted to the bottom of the magnetic rod B20210, the second feeding cylinder 2025 retracts upward, driving the metal part 4 to move upward and enter the through hole 20211, the first feeding cylinder 2023 extends and retracts according to the actual production situation, the picking robot arm 2020 moves again on the moving slide rail 2010 until it moves to the position of the injection mold 3050, and places the attracted metal part 4 on the injection mold 3050. This structure can accurately transport the columnar metal part 4 from the position of the feeding mechanism 1 to the injection mold 3050, which is safe and reliable.

[0063] The feeding mechanism 2 also includes a material picking drive mechanism and a material unloading drive mechanism (not shown in the figure). The material picking drive mechanism is used to drive the material picking sliding frame 2021 to move on the moving slide rail 2010, and the material unloading drive mechanism is used to drive the material unloading sliding frame 2031 to move on the moving slide rail 2010.

[0064] refer to Figure 9 The lifting seat B2024 is pushed by the first feeding cylinder 2023, which is located above the lifting seat B2024. The lifting seat B2024 is connected to the picking slider 2022. The first feeding cylinder 2023 drives the lifting seat B2024 to move up and down along the picking slider 2022. The first feeding cylinder 2023 is fixed on the picking sliding frame 2021. The lifting seat B2024 is connected to the picking slider 2022, thereby ensuring that the lifting seat B2024 moves up and down with the push of the first feeding cylinder 2023.

[0065] Furthermore, the second feeding cylinder 2025 is mounted on the lifting seat B2024, and the lifting seat B2024 is equipped with a fixing rod 20212. The second feeding cylinder 2025 is connected to the fixing rod 20212, and the through hole 20211 is located at the bottom of the lifting seat B2024.

[0066] refer to Figure 10The movable seat 2026 includes a connecting seat 2027 and parallel first movable plate 2028 and second movable plate 2029 disposed below the connecting seat 2027. The connecting seat 2027 is connected to a second feeding cylinder 2025. One end of the magnetic rod B20210 is disposed on the first movable plate 2028, and the other end extends out of the second movable plate 2029. The second feeding cylinder 2025 extends and retracts to propel the connecting seat 2027, and the connecting seat 2027 drives the first movable plate 2028 and the second movable plate 2029 to move up and down.

[0067] Furthermore, a fixing ring 20213 is fitted on the magnetic rod B20210. The fixing ring 20213 is located on the top surface of the second movable plate 2029. The fixing ring 20213 has a screw hole 20214 in the radial direction. The screw passes through the screw hole 20214 and tightens the magnetic rod B20210, which facilitates the replacement of the magnetic rod B20210.

[0068] Furthermore, the bottom of the movable base 2026 is also provided with a positioning rod 20215, the length direction of which is parallel to the length direction of the magnetic rod B20210. The working mold base 3052 is provided with an insertion hole, and the positioning rod 20215 cooperates with the insertion hole. Only when the positioning rod 20215 is inserted into the working mold base 3052 is the position determined, and the material handling robot arm 2020 delivers the metal part 4 to the working mold base 3052.

[0069] refer to Figure 11 The unloading robotic arm 2030 includes an unloading sliding frame 2031 that moves on a sliding rail 2010. An unloading slide rail rod 2032 is connected to the unloading sliding frame 2031. The unloading slide rail rod 2032 is driven by a third unloading cylinder 2033 and moves up and down along the unloading sliding frame 2031. A gripping mechanism 2034 is provided at the bottom of the unloading slide rail rod 2032.

[0070] After the metal part 4 is injection molded, the rotating platform 3030 rotates the injection mold 3050 to the opposite side of the injection head 3040. The unloading robotic arm 2030 grabs the injection molded metal part 4 from the injection mold 3050 and transports it to the collection area. The unloading robotic arm 2030 moves on the moving slide rail 2010, taking the metal part 4 from the injection mold 3050 and transporting it to the collection area. When the unloading robotic arm 2030 moves to the position of the injection mold 3050, the third unloading cylinder 2033 moves, driving the unloading slide rail 2032 and the gripping mechanism 2034 to move down. After moving down to a certain position, the third unloading cylinder 2033 stops moving, and the gripping mechanism 2034 begins to grip the metal part 4. After gripping, the third unloading cylinder 2033 resets, and the unloading robotic arm 2030 moves to the product collection area.

[0071] refer to Figure 12The gripping mechanism 2034 includes a fourth unloading cylinder 20341 and a fork 20342 connected to the fourth unloading cylinder 20341. The extension and retraction direction of the fourth unloading cylinder 20341 is perpendicular to the movement direction of the unloading slide rail 2032. The fork 20342 is shaped like a knife and fork, and the metal part 4 can be rested on the fork 20342, thereby allowing the fork 20342 to carry away the metal part 4.

[0072] refer to Figures 11-13 The unloading sliding frame 2031 is equipped with a fifth unloading cylinder 2035. The telescopic end of the fifth unloading cylinder 2035 is connected to an extension rod 2036. The extension rod 2036 passes through the gripping mechanism 2034. The end of the extension rod 2036 is connected to a pressing member 2037, which is located below the gripping mechanism 2034.

[0073] The pressing component 2037 includes two parallel pressing rods, with evenly spaced pressing posts at the bottom of the pressing rods. The working mold base 3052 is provided with a pressing groove 3055, which is used to accommodate the pressing rods and pressing posts. The pressing rods have a certain length, which makes the working mold base 3052 more evenly pressurized.

[0074] Before the gripping mechanism 2034 grips the metal part 4, the fifth unloading cylinder 2035 first drives the pressing part 2037 to move down. The pressing part 2037 presses down on the working mold base 3052. The working mold base 3052 moves down under the influence of the elastic force of the elastic mechanism 3053. Since the depth of the product groove 3054 is fixed, when the working mold base 3052 moves down, more of the metal part 4 is exposed on the working mold base 3052, making it easier for the gripping mechanism 2034 to grip the metal part 4.

[0075] refer to Figure 14 The fourth unloading cylinder 20341 has a fixed clamp 2038 on its telescopic end. The front end of the fixed clamp 2038 has a V-shaped opening for gripping the extension rod 2036. After the fifth unloading cylinder 2035 presses down on the working mold base 3052, the fourth unloading cylinder 20341 drives the fork 20342 to approach the metal part 4. At the same time, the fixed clamp 2038 also moves with the fork 20342. When the fixed clamp 2038 grips the extension rod 2036, the fourth unloading cylinder 20341 stops telescopicating, completing the gripping operation.

[0076] The third unloading cylinder 2033 is mounted on the unloading sliding frame 2031. The third unloading cylinder 2033 is a double-headed cylinder. Each telescopic end of the third unloading cylinder 2033 is connected to an unloading slider 2039. The unloading slider 2039 is connected to the unloading slide rail 2032 and slides along the unloading slide rail 2032. The unloading sliding frame 2031 is located between the two unloading sliders 2039.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
