Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and more specifically, to an injection molding equipment for producing data cables. Background Technology

[0002] In the process of processing data cables, vertical injection molding machines are often used for injection molding. The working principle of an injection molding machine is similar to that of a syringe. It uses the thrust of a screw to inject pre-plasticized molten plastic into a closed mold cavity, and then obtains the finished product after solidification.

[0003] Utility model patent application number CN216400338U discloses an auxiliary demolding device for a vertical injection molding machine used in the production of mobile phone data cables. Addressing the problems of cumbersome demolding and low production efficiency mentioned in the background technology, the present invention proposes the following solution: A base is included, and an ejection mechanism is provided on one side of the base. The ejection mechanism includes an air hole on the outer wall of the top of the base, an air pipe inserted into the inner wall of the air hole, a high-pressure air pump connected to the outer wall of one end of the air pipe, and a solenoid valve installed on the outer wall of the air pipe. This utility model, through the opening of the solenoid valve, allows the high-pressure air pump to compress air and blow it into the air hole along the air pipe, thereby ejecting the mold from the base, achieving a good auxiliary demolding effect. During the injection molding process, the operator can place another set of data cables into the mounting mechanism, securing the data cables in the slots, eliminating the need to rearrange the data cables during injection molding.

[0004] The aforementioned patent requires the operator to place the data cable to be injected onto the injection table using their hands. After injection, the operator also needs to remove the injected data cable from the injection table. Because the hydraulic cylinder seal of the injection molding machine is under high pressure and high frequency for a long time, it is prone to aging and failure over time. The upper mold may suddenly fall due to its own weight, directly hitting the operator below and causing irreparable damage.

[0005] Therefore, we have made improvements to this and proposed an injection molding equipment for data cable production. Utility Model Content

[0006] The purpose of this invention is to address the issue that the sealing ring of the hydraulic cylinder of an injection molding machine is prone to aging and failure due to long-term high-pressure and high-frequency operation. As a result, the upper mold may suddenly fall due to its own weight, directly hitting the personnel operating below and causing irreparable damage.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] With multiple protection mechanisms in the mold clamping assembly, even if the hydraulic cylinder seal ring fails, the upper mold will not suddenly fall due to its own weight, effectively avoiding the risk of serious injury to the operator and significantly improving the safety of the equipment. The precise fit and dual protection mechanism of the mold clamping assembly ensure the stability of the mold during the injection molding process and reduce the defect rate caused by mold loosening.

One end of the connecting frame is rotatably engaged with one side of the connecting block, and the other end of the connecting frame is rotatably engaged with the bottom of the locking template.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the multiple protection mechanisms of the mold clamping assembly, even if the oil cylinder seal ring of the hydraulic cylinder fails, the upper mold will not suddenly fall due to its own weight, effectively avoiding the risk of serious injury to the operator and significantly improving the safety of the equipment.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1: Please refer to Figure 1-4 A data cable manufacturing injection molding equipment includes: a base frame 1, an injection molding table 2 mounted on top of the base frame 1, a lower mold 3 mounted on top of the injection molding table 2, a fixing frame 4 mounted on top of the injection molding table 2, an upper mold 5 cooperating with the lower mold 3 located below the fixing frame 4, a mold locking assembly 6 provided between the upper mold 5 and the injection molding table 2, and two sliding rods 7 slidably cooperating with the upper mold 5 installed between the fixing frame 4 and the injection molding table 2. A feed box 8 is mounted on top of the fixing frame 4, and a feed pipe 9 is installed between the discharge port of the feed box 8 and the feed port of the upper mold 5. A hydraulic cylinder 10 is mounted on the fixing frame 4, and the end of the telescopic shaft of the hydraulic cylinder 10 is mounted on the upper side of the upper mold 5.

[0032] Implementation process: The injection material in the feed box 8 enters the feed port of the upper mold 5 through the feed pipe 9, and then is injected into the cavity formed by the upper mold 5 and the lower mold 3 to complete the injection molding of the data cable.

[0033] Benefits of implementation: The sliding engagement between the slide bar 7 and the upper mold 5 ensures that the upper mold 5 remains stable during lifting and lowering, reducing swaying and deviation.

[0034] Example 2: The mold clamping assembly 6 includes a locking template 601 that slides above the injection molding platform 2 and is located on both sides of the fixing frame 4. Locking modules 602 are installed on both sides of the upper mold 5. Multiple locking grooves 603 that mate with the locking modules 602 are opened on the sides of the locking templates 601. Connecting rods 608 are installed on opposite sides of the two locking templates 601. Connecting grooves 11 that slide with the connecting rods 608 are opened on both sides of the fixing frame 4. A cavity 605 is opened in the middle of the injection molding platform 2. Two through holes 12 communicating with the cavity 605 are opened on the side of the injection molding platform 2. Two through slots 13 communicating with the cavity 605 are opened on the upper side of the injection molding platform 2. Both through holes 12 have push rods 604 slidably fitted on their inner walls. Two push switches 606, each engaging with the ends of the push rods 604, are installed on the inner wall of the cavity 605. Connecting blocks 609, located within the cavity 605, are mounted around the periphery of the two push rods 604. A tension spring 610 is installed between one side of the connecting block 609 and the inner wall of the cavity 605. Connecting brackets 607 are provided between each of the two locking templates 601 and the two connecting blocks 609. One end of the connecting bracket 607 is rotatably engaged with one side of the connecting block 609, and the other end of the connecting bracket 607 is rotatably engaged with the bottom of the locking template 601.

[0035] Implementation process: When the hydraulic cylinder 10 is working normally, the upper mold 5 maintains a stable position under the drive of the hydraulic cylinder. The locking module 602 is embedded in the locking groove 603 of the locking template 601 to achieve mechanical locking. If the hydraulic system fails (such as pressure leakage caused by aging of the sealing ring), the hydraulic cylinder 10 cannot maintain the position of the upper mold 5. At this time, the upper mold 5 moves down due to its own weight, causing the locking modules 602 on both sides to disengage from the locking groove 603. The disengagement of the locking module 602 forces the locking template 601 to slide outward along the connecting groove 11 through the connecting rod 608. The movement of the locking template 601 pushes the push rod 604 into the cavity 605 through the connecting frame 607, triggering the press switch 606. The press switch 606 immediately cuts off the power supply of the equipment and starts the emergency brake to prevent the upper mold 5 from continuing to fall. When the hydraulic system is restored, the tension spring 610 pulls the connecting block 609 back to the initial position, and the locking template 601 is reset through the connecting frame 607. The locking groove 603 re-engages with the locking module 602, and the equipment can resume normal operation.

[0036] Benefits of implementation: The rigid engagement between the locking groove 603 and the locking module 602 can provide physical support in the early stages of hydraulic failure.
