The through hole 311 penetrates the lower mold core 31 along the thickness direction of the lower mold core 31. The ejector pin 32 passes through the through hole 311 and protrudes from the upper surface of the lower mold core 31.

[0045] The metal feeding assembly 5 includes a feeding component 51 and a transfer robot 52. The transfer robot 52 transfers the outer ring 101 inside the feeding component 51 to the lower mold 3 and sleeves the ring 101 on the ejector pin 32.

[0046] The ejector pin 32 includes a rod body 321 and a rod head 322 connected in sequence. The rod body 321 passes through a through hole 311, and the rod head 322 protrudes out of the through hole 311. The radial dimension of the rod head 322 is smaller than that of the rod body 321.

[0047] Specifically, in this embodiment, the lower mold 3 includes a lower mold core 31, which is machined with several through holes 311. An ejector pin 32 mates with one of the through holes 311. The rod 321 of the ejector pin 32 passes through the through hole 311, and the rod head 322 of the ejector pin 32 protrudes out of the through hole 311. The metal feeding assembly 5 includes a feeding component 51, which is used to accommodate several external rings 101. First, the driving component 2 drives the lower mold 3 to move so that the lower mold 3 approaches the feeding component 51. The transfer robot 52 then moves the feeding component 51. One of the rings 101 inside is taken out and transferred to the top of the lower mold core 31. Then, the ring 101 is put on the rod head 322. This action is repeated multiple times, with one ring 101 put on one rod head 322. Then, the driving component 2 drives the lower mold 3 to move to the bottom of the upper mold 4. The lower mold 3 and the upper mold 4 close to complete the injection molding of the plastic part 102, that is, the assembly and molding of the ring 101 and the plastic part 102 are completed simultaneously. The upper mold 4 and the lower mold 3 open to remove the molded part, thus completing the assembly and molding of the metal and plastic parts.

[0048] Driven by the drive unit 2, the lower mold 3 moves back and forth between the metal feeding assembly 5 and the upper mold 4. The transfer robot 52 of the metal feeding assembly 5 transfers the ring 101 in the feeding component 51 to the lower mold 3 and puts the ring 101 on the rod head 322. Then, the drive unit 2 drives the lower mold 3 to move to the lower mold 4. The upper mold 4 and the lower mold 3 close to complete the molding of the plastic part. That is, the assembly and molding of the metal and plastic parts are completed simultaneously, which improves production efficiency and the assembly firmness of the metal and plastic parts.

[0049] The rod head 322 includes a straight body 3221 and a pointed head 3222 connected in sequence. The straight body 3221 is connected to the rod body 321. The radial dimension of the pointed head 3222 gradually decreases in the direction away from the straight body 3221. The pointed head 3222 is designed to facilitate the ring body 101 to first fit into the pointed head 3222 to complete the pre-assembly, and then the ring body 101 is pressed down and tightened with the straight body 3221.

[0050] The feeding component 51 includes a material box 511 and a vibratory feeder 512. The discharge port of the material box 511 is located directly above the vibratory feeder 512. The material box 511 is used to accommodate several randomly placed external rings 101. Some of the rings 101 enter the vibratory feeder 512 from the material box 511. Through the vibration of the vibratory feeder 512, the placement state of some of the rings 101 in the vibratory feeder 512 meets the transfer requirements. The transfer robot 52 transfers the rings 101 that meet the requirements to the lower mold 3 and puts them into the rod head 322.

[0051] The transfer robot 52 includes a vision sensor 521, a swing drive 522, and a suction cup 523. The vision sensor 521 controls the movement of the swing drive 522, and the swing drive 522 holds the suction cup 523. The vision sensor 521 captures an image of the ring 101 inside the vibrating plate 512, and the image information is transmitted to the control system. The control system controls the swing drive 522 to pick up the ring 101 with the composite transfer requirements through the suction cup 523. The control system controls the movement of the swing drive 522 to simultaneously transfer the ring 101 to the lower mold 3.

[0052] The injection molding machine for the metal-plastic composite parts also includes a connecting rod 6, and there are two lower molds 3 connected by the connecting rod 6. The output shaft of the drive unit 2 is connected to one of the lower molds 3.

[0053] The number of metal feeding components 5 is two. The two metal feeding components 5 respectively feed material to the two lower molds 3. This structure enables the metal feeding component 5 to feed material to one of the lower molds 3, while the other lower mold 3 closes with the upper mold 4 to complete the injection molding. The structure of the two lower molds 3 feeding material and closing the mold alternately improves production efficiency.

[0054] The injection molding machine for the metal-plastic composite parts also includes a guide 7, in which two lower molds 3 are slidably connected. This structure ensures the stability of the movement direction of the two lower molds 3 and the accuracy of the mold closing between the lower molds 3 and the upper mold 4.

[0055] The two metal feeding components 5 are located on both sides of the guide 7 along its length, so that the two lower dies 3 move along the length of the guide 7 and cooperate with the corresponding metal feeding components 5 to complete the feeding of the outer ring 101.

[0056] The guide member 7 includes a left side plate 71, a bottom plate 72, and a right side plate 73 connected in sequence. The left side plate 71 and the right side plate 73 are both located on the same side of the bottom plate 72. The left side plate 71, the bottom plate 72, and the right side plate 73 are connected in a U-shaped structure, which plays a role in bearing and controlling the movement direction of the lower mold 3.

[0057] The guide member 7 also includes a left baffle 74 and a right baffle 75. The left baffle 74 and the right baffle 75 are located on both sides of the base plate 72 along its length. The left baffle 74 is located close to one metal feeding assembly 5, and the right baffle 75 is located close to another metal feeding assembly 5. The left baffle 74 and the right baffle 75 limit the two lower dies 3 respectively, so as to avoid the lower dies 3 from colliding with the metal feeding assembly 5 and improve production safety.
