Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, in particular to an intelligent and efficient injection molding device. Background Art

[0002] Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding is achieved through injection molding machines and molds.

[0003] There are some problems with existing injection molding devices. For example, after the mold is replaced, the position between the mold's injection port and the injection head is offset, making it inconvenient for the injection head to align with the mold's injection port. Since the molds are of different sizes, it is inconvenient to fix the mold, thereby slowing down the speed of mold injection.

[0004] After searching, the patent publication number is CN216329638U, which is an intelligent and efficient injection molding device. The device includes an injection molding frame, a connecting frame, a workbench, a placement frame, etc. Although it can solve the technical problems existing in the prior art when used, it still has certain disadvantages in actual use. When replacing or disassembling the mold, since the connecting frame is directly above the mold and there is obstruction, it is necessary to use a hydraulic telescopic rod to push the mold to adjust its position left and right, and then hoist the mold. Due to the obstruction of the connecting frame, the mold can only be hoisted from both sides of the connecting frame. In this way, the lifting space left for the mold will be very small, and it is easy to bump into the parts on the connecting frame, affecting the hoisting of the mold. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an intelligent and efficient injection molding device that can leave more space for mold hoisting, avoid the mold from colliding with parts on the connecting frame during hoisting, and facilitate the hoisting of the mold.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent and efficient injection molding device, comprising an injection molding frame, a pull rod mechanism and a positioning mechanism, a connecting frame is slidably mounted on the injection molding frame, the bottom end of the injection molding frame is fixedly connected to a workbench, a placement frame is fixedly provided on the workbench, the pull rod mechanism comprises a pull rod, a notch is provided at the right end of the injection molding frame, the pull rod is slidably mounted on the injection molding frame by cooperating with the notch, a handle is fixedly connected to the right end of the pull rod, a connecting rod is hinged to the left end of the pull rod, the left end of the connecting rod is fixedly connected to the right end of the connecting frame, and sliding grooves are provided at both the front and rear ends of the inner side of the injection molding frame , sliders are fixed at both ends of the front and rear of the connecting frame, and the connecting frame is slidably installed on the connecting frame through the cooperation of the slider and the slide groove. Two sets of blocks are fixed symmetrically at the left middle position on the inner side of the injection molding frame, and the left end of the connecting frame rests on the two sets of blocks. The positioning mechanism includes a positioning column, a sliding hole is provided in the center of the top right side of the injection molding frame and is connected to the slot.

Two sets of blocks 9 are fixed symmetrically on the left side of the middle of the inner side of the injection frame 1. The left end of the connecting frame 2 is against the two sets of blocks 9. A sliding hole is provided in the center of the top right side of the injection frame 1 connected to the notch. The positioning column 10 is slidably installed on the injection frame 1 by cooperating with the sliding hole. A hand ring 11 is fixedly connected to the top of the positioning column 10. A positioning hole 12 and a positioning hole 2 13 are respectively passed through the pull rod 5 and the connecting rod 7, and the positioning hole 12 and the positioning hole 2 13 are on the top. When in use, the left end of the connecting frame 2 is initially against the stop block 9, and the positioning column 10 is inserted into the positioning hole 12, so that the connecting frame 2 is in the middle position of the injection frame 1. When the mold is hoisted, the positioning column 10 is pulled out from the positioning hole 12 through the hand ring 11, and then the pull rod 5 is pulled horizontally to the right through the pull handle 6, so that the pull rod 5 drives the connecting frame 2 to slide to the right through the connecting rod 7 until the right end of the connecting frame 2 contacts the right inner wall of the injection frame 1. At this time, the right end of the connecting rod 7 slides out of the notch, and the positioning hole 2 13 is aligned with the positioning column 10, and then the mold is lifted by the hand ring 11. The ring 11 inserts the positioning column 10 into the positioning hole 2 13 to position the connecting rod 7 and prevent the connecting frame 2 from moving. Chamfers are set on the positioning hole 12 and the positioning hole 2 13 to make it easier to insert the positioning column 10 into the positioning hole 12 and the positioning hole 2 13. By moving the connecting frame 2 to the rightmost end, the space left by the injection molding frame 1 for the mold is increased, avoiding the mold from hitting the components on the connecting frame during hoisting, thereby facilitating the hoisting of the mold, and after being pulled out, the pull rod 5 can be rotated to a vertical downward state to reduce the space occupied by the pull rod 5.

Its working principle is that when in use, the left end of the connecting frame 2 is initially against the stop block 9, and the positioning column 10 is inserted into the positioning hole 12, so that the connecting frame 2 is in the middle position of the injection molding frame 1. When the mold is hoisted, the positioning column 10 is pulled out from the positioning hole 12 by the hand ring 11, and then the pull rod 5 is pulled horizontally to the right by the pull handle 6, so that the pull rod 5 drives the connecting frame 2 to slide to the right through the connecting rod 7 until the right end of the connecting frame 2 contacts the right inner wall of the injection molding frame 1. At this time, the right end of the connecting rod 7 slides out of the notch, and the positioning hole 13 is aligned with the positioning column 10. Then, the positioning column 10 is inserted into the positioning hole 12 by the hand ring 11. 3, the connecting rod 7 is positioned to prevent the connecting frame 2 from moving. Chamfers are set on the positioning hole 12 and the positioning hole 2 13 to make it easier to insert the positioning column 10 into the positioning hole 12 and the positioning hole 2 13. By moving the connecting frame 2 to the rightmost end, the space left by the injection molding frame 1 for the mold is increased, which prevents the mold from hitting the components on the connecting frame during hoisting, thereby facilitating the hoisting of the mold. After being pulled out, the pull rod 5 can be rotated to a vertical downward state to reduce the space occupied by the pull rod 5. After the mold is placed, the connecting frame 2 is pushed back to the middle position of the injection molding frame 1, and the positioning column 10 is inserted into the positioning hole 12 to fix the position.
