Description

Technical Field

[0001] The invention relates to the technical field of injection molding devices, in particular to an injection molding device for processing an outer rubber hose of a hydraulic oil pipe. Background Art

[0002] In the field of intelligent manufacturing equipment, hydraulic hoses serve as core power transmission components for industrial equipment, construction machinery, and hydraulic transmission systems. Their reliability is directly linked to the safe operation of the entire system. The outer hose (external protective hose) of the hydraulic hose, as a protective structure that comes into direct contact with the external environment, is crucial for its performance. It resists physical damage from friction, collision, and extrusion, extending the overall service life of the hydraulic hose. Currently, injection molding is the industry's most widely used process for producing shorter outer hoses of hydraulic hoses. This process involves injecting molten rubber, nylon, polyethylene, or polypropylene into the mold cavity under high pressure, creating a protective hose in a single step.

[0003] When traditional injection molding devices are processing hydraulic oil pipe outer rubber hoses, when the molded outer rubber hoses need to be demolded, due to the long length of the outer rubber hoses and the lack of automatic energy-saving auxiliary demolding structure in the existing injection molding devices, the molded outer rubber hoses need to be demolded manually with the help of tools, which not only increases labor costs but also reduces production efficiency. Moreover, the processed outer rubber hoses need to be picked up manually and placed in the collection box. The whole process is time-consuming and labor-intensive. What's more troublesome is that the outer rubber hoses placed in the collection box are prone to accumulation. In order to increase the effective collection volume of the collection box, the staff have to manually level the outer rubber hoses in the collection box, which further increases the workload. Summary of the Invention

Moreover, the driving block 703 is located on the inner side of the handle 702, which is more convenient when holding it tightly.

[0033] The working principle of the present invention is as follows: when in use, the driving motor 302 is first controlled by the external controller to operate, and the upper threaded rod 301, the upper sprocket 303, the lower sprocket 303 and the lower threaded rod 301 are rotated synchronously. At this time, the sliding plate 205 moves linearly to the left with the sealing plate 208 under the action of the thread, so that the left end face of the sealing plate 208 is in close contact with the right end faces of the outer mold 203 and the inner mold 204, and at this time, the right end face of the push rod 503 is aligned with the left end faces of the outer mold 203 and the inner mold 204, and then The injection device 4 injects molten rubber or other materials into the space between the outer mold 203 and the inner mold 204 through the feed port 209, thereby forming an outer rubber tube. The drive motor 302 is then controlled to rotate in the opposite direction, causing the upper threaded rod 301, the upper sprocket 303, the lower sprocket 303, and the lower threaded rod 301 to rotate in the opposite direction synchronously. At this time, the sliding plate 205, under the action of the threads, moves the sealing plate 208 in a straight line to the right, so that the left end surface of the sealing plate 208 is separated from the outer mold 203 and the right end surface of the inner mold 204. When the sliding plate 205 moves to the right, it will carry the L-shaped driving plate 501, the spring guide rod 504, the connecting plate 502 and the pushing rod 503 to move to the right. At this time, the pushing rod 503 pushes the outer rubber tube formed between the outer mold 203 and the inner mold 204 to the right. When the sliding plate 205 moves to the right to the limit position, the right end face of the pushing rod 503 is flush with the right end faces of the outer mold 203 and the inner mold 204. At this time, the outer rubber tube formed between the outer mold 203 and the inner mold 204 can be ejected, realizing automatic demoulding. In the demoulding process, no manual tools are required. The demoulding can be completed, which not only effectively reduces the labor cost, but also significantly improves the production efficiency, and when the automatic demoulding mechanism 5 is in operation, there is no need to equip additional driving devices such as electric cylinders, which is more energy-saving; then the outer rubber tube falls onto the upper inclined surface of the guide ramp A206, and rolls to the upper inclined surface of the guide ramp B207 under the action of gravity, and then automatically rolls to the inside of the collection box 7 through the upper inclined surface of the guide ramp B207, and is automatically collected. Therefore, the processed outer rubber tube does not need to be picked up manually and placed in the collection box 7, making the entire processing process more time-saving and labor-saving.

[0034] During the rotation of the lower threaded rod 301, the active bevel gear drives the driven bevel gear, the linkage shaft 604, the active pulley, the driven pulley, the vertical rotating shaft 605 and the circular driving disk 603 to rotate, and the circular driving disk 603 drives the rear end of the connecting rod 606 to rotate, and the front end of the connecting rod 606 drives the shaking plate 601 to move back and forth, and the shaking plate 601 drives the collection box 7 to shake back and forth, so that the external rubber tubes collected inside the collection box 7 are automatically leveled under the action of shaking, so that the staff does not need to manually level the external rubber tubes in the collection box 7, further reducing the workload.

[0035] When the outer rubber tube collected inside the collection box 7 needs to be transported to the next process, the staff can hold the handle 702 and the driving block 703 with their hands, and then hold the driving block 703 toward the outside of the handle 702, and move the upper end of the driving rope 904 outward, and the lower end of the driving rope 904 moves upward with the hexagonal prism 902 and the rectangular tube body 901, and then move the two adjacent T-shaped pull rods 804 toward each other through the inclined opening 905 in the shape of an inverted eight, thereby moving the two adjacent rectangular sliders 802 and the two adjacent plug-in blocks 803 toward each other, so that the plug-in block 803 is pulled out from the inside of the rectangular socket 608, and then the collection box 7 is lifted and the outer rubber tube can be transported.

[0036] When the material collection box 7 needs to be installed on the upper part of the shaking plate 601, first align the positioning pin 701 with the positioning socket 609, then drop the material collection box 7 vertically to connect the positioning pin 701 with the positioning socket 609, and at this time, the plug-in block 803 automatically retracts a distance under the action of the chamfer at its head end, and then automatically inserts into the rectangular socket 608, thereby realizing the rapid installation of the material collection box 7. The entire installation process can be easily completed without any tools, thereby greatly improving the convenience of using the injection molding device.
