Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, and in particular to an injection molding device for processing hydraulic hose outer tubing. Background Technology

[0002] In the field of intelligent manufacturing equipment, hydraulic hoses, as core power transmission components of industrial equipment, engineering machinery, and hydraulic transmission systems, are directly related to the safe operation of the entire system. The outer rubber hose (external protective hose) of the hydraulic hose, as a protective structure directly exposed to the external environment, has crucial protective performance. It can resist physical damage such as friction, collision, and compression, extending the overall service life of the hydraulic hose. Currently, for the processing of shorter hydraulic hose outer rubber hoses, the industry commonly uses injection molding. This process involves injecting molten rubber, nylon, polyethylene, or polypropylene into a mold cavity under high pressure, forming the protective hose in a single step.

[0003] In the process of processing hydraulic hoses using traditional injection molding equipment, when demolding the formed hoses is required, the hoses are often too long, and existing injection molding equipment lacks an automatic and energy-saving demolding mechanism. This means that the formed hoses must be demolded manually with the aid of tools, which not only increases labor costs but also reduces production efficiency. Furthermore, the processed hoses must be manually picked up and placed into a collection box, a process that is both time-consuming and labor-intensive. To make matters worse, the hoses tend to accumulate in the collection box, requiring workers to manually level them to increase the effective collection capacity, further increasing the workload. Summary of the Invention

[0015] This invention provides an injection molding apparatus for processing hydraulic hose outer tubing, which has the following beneficial effects: I. This invention, through the design of an automatic demolding mechanism, can eject the outer rubber tube formed between the outer mold and the inner mold during the movement of the sliding plate to the right, thereby achieving automatic demolding. This process does not require manual assistance with tools, which can effectively reduce labor costs and significantly improve production efficiency. Moreover, the automatic demolding mechanism does not require additional drive devices such as electric cylinders during operation, thus being more energy-efficient.

[0016] Second, through the design of guide plate A and guide plate B, the outer rubber tube will fall onto the upper inclined surface of guide plate A after demolding. Under the action of gravity, it will roll onto the upper inclined surface of guide plate B, and then automatically roll into the collection box through the upper inclined surface of guide plate B for automatic collection. This design replaces the traditional manual picking and placing operation, making the entire processing flow more efficient and convenient, significantly improving production efficiency and reducing manual labor intensity.

[0017] Third, through the design of the shaking mechanism, this invention enables the rotation of a threaded rod at the bottom. During this rotation, the driving bevel gear drives the driven bevel gear, the linkage shaft, the driving pulley, the driven pulley, the vertical rotating shaft, and the circular drive disc to rotate. The circular drive disc drives the rear end of the connecting rod to rotate, and the front end of the connecting rod drives the shaking plate to move back and forth. The shaking plate causes the collection box to shake back and forth. This mechanism automatically arranges the outer rubber tubes in the collection box neatly under the mechanical shaking action, eliminating the manual leveling operation in the traditional process, greatly improving the degree of production automation, and significantly reducing the workload of workers.

[0018] Fourth, through the design of the quick-positioning component, when the material collection box needs to be installed on the upper part of the swaying plate, it is only necessary to align the positioning pin with the positioning hole, and then drop the material collection box vertically. At this time, the insertion block automatically retracts a distance under the action of its head chamfer, and then automatically inserts into the rectangular insertion hole, realizing the quick installation of the material collection box. The entire installation process can be easily operated without the aid of any tools, which significantly improves the convenience of using this injection molding device.

[0019] V. Through the design of the synchronous drive component, this invention allows for easy removal of the collection box by simply gripping the drive block outwards from the handle. This moves the upper end of the drive rope outwards, while the lower end of the drive rope moves the hexagonal prism and rectangular tube upwards. Then, through the inverted V-shaped inclined opening, it moves the two adjacent T-shaped pull rods towards each other, thereby moving the two adjacent rectangular sliders and the two adjacent plug-in blocks towards each other. This allows the plug-in blocks to be pulled out from inside the rectangular socket, eliminating the need to pull out the plug-in blocks one by one. Furthermore, the drive block is located inside the handle, making gripping and operation more convenient and greatly improving the ease of removing the collection box. Attached Figure Description

[0032] Example 2, based on Example 1, such as Figures 7 to 9 As shown, the synchronous drive component 9 includes a rectangular tube 901.

Through the setting of the synchronous drive component 9, the collection box 7 can be removed. When the lever 703 is gripped outwards from the handle 702, the upper end of the lever 904 moves outwards. Then, the lower end of the lever 904 moves the hexagonal prism 902 and the rectangular tube 901 upwards. Next, through the inverted V-shaped inclined opening 905, it moves the two adjacent T-shaped pull rods 804 towards each other, thereby moving the two adjacent rectangular sliders 802 and the two adjacent plug blocks 803 towards each other. This allows the plug blocks 803 to be pulled out from inside the rectangular socket 608, eliminating the need to pull out the plug blocks 803 one by one. Moreover, the lever 703 is located inside the handle 702, making it more convenient to grip and operate.

[0033] The working principle of this invention is as follows: In use, the drive motor 302 is first controlled by an external controller, causing the upper threaded rod 301, upper sprocket 303, lower sprocket 303, and lower threaded rod 301 to rotate synchronously. At this time, the sliding plate 205, under the action of the threads, moves the sealing plate 208 linearly to the left, causing the left end face of the sealing plate 208 to make close contact with the right end face of the outer mold 203 and the inner mold 204. Simultaneously, the right end face of the push rod 503 is aligned with the left end face of the outer mold 203 and the inner mold 204. The injection device 4 injects molten rubber and other materials through the feed port 209 into the space between the outer mold 203 and the inner mold 204 to form an outer rubber tube. Then, the drive motor 302 is 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 synchronously in the opposite direction. At this time, the sliding plate 205 moves the sealing plate 208 to the right in a straight line under the action of the thread, so that the left end face of the sealing plate 208 is separated from the right end face of the outer mold 203 and the inner mold 204. As the sliding plate 205 moves to the right, it will also move the L-shaped drive plate 501, spring guide rod 504, connecting plate 502, and push rod 503 to the right. At this time, the push 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 its limit position to the right, the right end face of the push 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 demolding. During the demolding process, no manual tools are required. Demolding can be completed in one step, which not only effectively reduces labor costs but also significantly improves production efficiency. Furthermore, the automatic demolding mechanism 5 does not require additional drive devices such as electric cylinders, thus saving energy. Then, the outer tube falls onto the upper inclined surface of the guide plate A206 and rolls onto the upper inclined surface of the guide plate B207 under the action of gravity. Then, it automatically rolls onto the upper inclined surface of the guide plate B207 and into the collection box 7 for automatic collection. Therefore, the processed outer tube does not need to be manually picked up and placed into 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 driven bevel gear, driven bevel gear, linkage shaft 604, drive pulley, driven pulley, vertical rotating shaft 605 and circular drive disc 603 rotate through the drive bevel gear. The circular drive disc 603 drives the rear end of the connecting rod 606 to rotate, and the front end of the connecting rod 606 drives the swaying plate 601 to move back and forth. The swaying plate 601 drives the collection box 7 to sway back and forth, so that the outer rubber tubes collected inside the collection box 7 are automatically leveled by the swaying action. This eliminates the need for workers to manually level the outer rubber tubes in the collection box 7, further reducing the workload.

[0035] When it is necessary to move the outer rubber tube collected inside the collection box 7 to the next process, the worker can hold the handle 702 and the drive block 703 by hand, and then tighten the drive block 703 towards the outside of the handle 702, moving the upper end of the drive rope 904 outward. The lower end of the drive rope 904 moves the hexagonal prism 902 and the rectangular tube 901 upward. Then, through the inverted V-shaped inclined opening 905, it moves the two adjacent T-shaped pull rods 804 towards each other, thereby moving the two adjacent rectangular sliders 802 and the two adjacent plug blocks 803 towards each other, so that the plug blocks 803 are pulled out from the rectangular plug 608. Then, the collection box 7 is lifted and the outer rubber tube is moved.

[0036] When the material collection box 7 needs to be installed on the upper part of the swaying plate 601, first align the positioning pin 701 with the positioning hole 609, then lower the material collection box 7 vertically so that the positioning pin 701 is inserted into the positioning hole 609. At this time, the insertion block 803 automatically retracts a distance under the action of its chamfered head end, and then automatically inserts into the rectangular socket 608, realizing the quick installation of the material collection box 7. The entire installation process can be easily completed without any tools, thus greatly improving the convenience of using this injection molding device.
