[0044] In addition, the present application also relates to a multi-cavity injection molding system processing process with a split type mold core structure, comprising the following steps:

[0045] Step one: the components such as the bottom plate 1, the mold 2 and the injection molded part 3 are prepared in place;

[0046] Step two: a plurality of mold main bodies 21 are assembled on the bottom plate 1 according to the design requirements, and the positions of the mold main bodies 21 are ensured to be accurate;

[0047] Step 3: Install the feeding assembly 22 on the top of the mold body 21 so that the injection tube 222 can slide smoothly and align with the injection top tube 38;

[0048] Step 4: Install the injection molded part 3 on the top of the mold body 21 and debug the hydraulic push rod 34;

[0049] Step 5: According to the requirements of the injection molding material, set the working parameters of the injection molding machine, including injection pressure, injection speed, and injection temperature, to ensure that the injection molding process is stable and controllable;

[0050] Step 6: Connect the material passing pipe to the injection molding jack 38, start the injection molding machine, and perform the injection molding operation. During the injection molding process, pay attention to the closing condition of the mold cavity shell 2113 and the molding condition of the injection molded part;

[0051] Step 7: After the injection molding is completed, wait for the mold cavity shell 2113 to cool down, then drive the columnar push rod 2115 to push the push-pull side plate 2114 to open the mold cavity shell 2113 and take out the molded injection molded part;

[0052] Step 8: Carry out quality inspection on the taken out injection molded parts, package them after passing the inspection, and prepare them for shipment. At the same time, clean and maintain the mold to prepare for the next injection molding operation.

[0053] Working principle of the present invention: During the injection molding operation, the material passing pipe needs to be connected to the multiple injection molding jacking pipes 38 first. After the connection is completed, the hydraulic push rod 34 is started, and the hydraulic push rod 34 starts to work, pulling the injection molding jacking pipe connecting plate 35 to move downward. As the injection molding jacking pipe connecting plate 35 moves downward, the multiple injection molding jacking pipes 38 will also move downward, thereby pressing the multiple injection molding pipes 222 to move downward. During the downward movement of the multiple injection molding pipes 222, the outer C-shaped side rods 22 5 drives multiple sets of push-pull vertical rods 226 to move downward. After the multiple sets of push-pull vertical rods 226 move downward, they will pull multiple sets of lifting plates 227 to move downward. During the downward movement of the multiple sets of lifting plates 227, the L-shaped abutting blocks 228 on the outside will push the rotating wheel 2111 to rotate. When the rotating wheel 2111 rotates, the rotating wheel 2111 will drive the injection tube fixing plate 219 to move inward through the rotating wheel connecting block 2110. When the injection tube fixing plate 219 moves inward, it will be fixed on the injection tube 222. At the same time, when the injection tube fixing plate 219 moves inward, the two sets of push-pull side plates 2114 on the outside will be driven to move inward, so that the mold cavity shell 2113 in each mold body 21 is closed. At this time, the bottom of the injection tube 222 is located in the middle of the top of the closed mold cavity shell 2113. At this time, the raw material in the injection tube 222 will be injected into the mold cavity shell 2113 through the injection tube 222 for molding. When the injection molding is completed, the hydraulic The push rod 34 is reset, driving the injection molding top tube 38 to move upward. At this time, the injection molding tube 222 loses pressure. Under the elastic action of the ring cross connecting rod 224 and the C-shaped side rod 225, the injection molding tube 222 will automatically reset and wait for the next injection. At the same time, the columnar cross push rod 2115 will push the push-pull side plate 2114 to slide on the inner side of the side guide cross rod 2112 under the drive of an external power source, thereby driving the mold cavity shell 2113 to slide on the left and right sides of the inner wall of the U-shaped frame 211 to realize the opening and closing of the mold.
