Description

Technical Field

[0001] This invention discloses a polymer component manufacturing equipment, specifically a polymer chain ring manufacturing equipment with controllable length. Background Technology

[0002] Chain links are commonly used structural components, often used for connecting parts and transmitting power, and are frequently used in fields such as mechanical suspension.

[0003] Currently, commonly used chain links are made of metal. Although they have high strength and can meet the requirements of high tensile strength, they are also heavy and their surfaces are prone to corrosion, making them unsuitable for some environments with lower strength requirements. In order to solve the weight problem of metal chain links, researchers have developed polymer chain links, which are manufactured by injection molding of polymer materials.

[0004] However, in the current production of polymer chain links, injection molding of polymer chain links of different lengths requires the use of customized injection molds of corresponding specifications, and the length of polymer chain links cannot be flexibly processed and manufactured according to actual requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a controllable length polymer chain ring manufacturing equipment to solve the problem that existing polymer chain ring injection molding requires customized injection molds of corresponding specifications for different length specifications, and the length of polymer chain rings cannot be flexibly processed and manufactured according to actual requirements.

[0006] To achieve the above objectives, the present invention provides a polymer chain ring manufacturing apparatus with controllable length, comprising:

[0007] The processing table has two sets of operating tables fixedly installed vertically. Each set of operating tables has three sets of sliding grooves arranged in parallel. A set of sliders is linearly slidably installed in the sliding grooves. A set of transmission columns is slidably installed vertically on each set of sliders. The bottom of each set of transmission columns is horizontally connected to a first mounting column, a second mounting column, and a third mounting column. The lengths of the first mounting column, the second mounting column, and the third mounting column are successively shortened.

[0008] The injection molding module includes a first mold, a second mold, and a third mold. Each of the first mold, the second mold, and the third mold has staggered chain-link injection cavities. The adjacent sides of the first mold and the second mold abut to form an injection cavity for injection of horizontal hinges, and the adjacent sides of the second mold and the third mold abut to form an injection cavity for injection of vertical hinges. The adjacent horizontal hinges and vertical hinges are hinged together. The first mold, the second mold, and the third mold are all formed by the abutment of four component modules.

[0009] The injection molding machine is fixedly installed on the side plate of the processing table. It is used to align with the injection ports on the first mold, the second mold and the third mold to perform injection molding operations on the corresponding sealing cavities.

[0010] The separation structure consists of three sets. The first mold, the second mold, and the third mold are installed in the corresponding separation structure. Each set of separation structures includes two sets of horizontally mirror-symmetrical separation half-rings. A rotary motor is fixedly installed on the outer side of the arc apex of each separation half-ring. The rotary motor is used to drive the corresponding separation half-ring to rotate horizontally. The three sets of rotary motors are fixedly connected to the corresponding first mounting post, second mounting post, and third mounting post through connecting posts.

[0011] Two sets of limiting slide grooves are fixedly installed on the processing table in the vertical direction. The limiting slide groove includes an arc-shaped half-groove and a straight groove. The slider slides back and forth along the sliding groove, which drives the connecting column and the corresponding connecting separation half-ring to move back and forth along the limiting slide groove. The connection between the arc-shaped half-groove and the straight groove is provided with a guide block for the one-way sliding of the limiting connecting column.

[0012] Two sets of screw assemblies are installed inside the separation semi-ring, and the four sets of screw assemblies drive the corresponding four component modules inside the separation structure to demold.

[0013] As a further embodiment of the present invention, an electric sliding track is installed in the sliding groove, and the slider is fixedly connected to the electric slider in the electric sliding track, so that the slider slides synchronously driven by the sliding of the electric slider.

[0014] As a further embodiment of the present invention, the guide block is slidably installed at the connecting hole provided at the corner of the limiting slide groove, and is elastically connected to the fixing block on the outer wall of the limiting slide groove by a helical spring.

[0015] As a further embodiment of the present invention, an installation frame is fixedly installed inside the separating semi-ring, and a positioning rod is provided on the outside of the sub-module, the positioning rod being slidably connected to the low-position hole on the installation frame.

[0016] As a further embodiment of the present invention, the screw assembly includes a fixed screw, which is fixedly installed on the outside of the sub-module and forms a helical pair transmission with a rotary nut rotatably installed on the mounting frame. The two sets of rotary nuts are driven to rotate synchronously by a power component on the mounting frame.

[0017] As a further embodiment of the present invention, the power component includes a dual-head synchronous motor, wherein the rotating shafts at both ends of the dual-head synchronous motor form a helical pair transmission with the corresponding rotating nuts through a bevel gear set.

[0018] As a further aspect of the present invention, the connecting column is provided with a limiting ring for sliding connection limiting groove.

[0019] Compared with existing technologies, this invention designs an injection molding module, an injection molder, a separation structure, and limiting grooves. The injection molding module includes a first mold, a second mold, and a third mold, which are installed in corresponding separation structures. Two sets of limiting grooves are fixedly installed on the processing table in the vertical direction. The limiting grooves include arc-shaped semi-grooves and straight grooves. During the injection molding process, the positions of the first mold, the second mold, and the third mold can be sequentially interchanged to complete the injection molding requirements of horizontal and vertical chain links in sequence. Moreover, the corresponding injection cavity is in a closed state during injection molding, ensuring the quality of injection molding. This solves the problem that existing methods require customized injection molds for different lengths of polymer chain links, and the length of polymer chain links cannot be flexibly processed and manufactured according to actual requirements.

Detailed Implementation

[0029] In an embodiment of the present invention, a controllable length polymer chain ring manufacturing device includes:

[0030] like Figure 1 and Figure 2 As shown, a processing table 1 has two sets of operating tables 3 fixedly installed vertically on it. Each set of operating tables 3 has three sets of sliding grooves arranged in parallel. A set of sliders 303 is linearly slidably installed in the sliding grooves. A set of transmission columns 4 is slidably installed vertically on each set of sliders 303. The bottom of each set of transmission columns 4 is horizontally connected to a first mounting column 801, a second mounting column 802, and a third mounting column 803. The lengths of the first mounting column 801, the second mounting column 802, and the third mounting column 803 are successively shortened.

[0031] like Figure 4 , Figure 5 as well as Figure 6 As shown, the injection molding module 7 includes a first mold 701, a second mold 702, and a third mold 703. Each of the first mold 701, the second mold 702, and the third mold 703 has staggered chain-link injection cavities. The adjacent sides of the first mold 701 and the second mold 702 abut against each other to form an injection cavity for injection molding a horizontal hinge. The adjacent sides of the second mold 702 and the third mold 703 abut against each other to form an injection cavity for injection molding a vertical hinge. The adjacent horizontal hinges and vertical hinges are hinged together. The first mold 701, the second mold 702, and the third mold 703 are all formed by the abutment of four component modules 704.

[0032] like Figure 1 As shown, the injection molding machine 9 is fixedly installed on the side plate of the processing table 1. It is used to align with the injection ports on the first mold 701, the second mold 702 and the third mold 703 to perform injection molding operations on the corresponding sealing cavities.

[0033] like Figure 7 and Figure 8 As shown, there are three sets of separation structures 6. The first mold 701, the second mold 702 and the third mold 703 are installed in the corresponding separation structure 6. Each set of separation structures 6 includes two sets of horizontally mirror-symmetrical separation semi-rings 601. A rotary motor 10 is fixedly installed on the outer side of the arc apex of the separation semi-ring 601. The rotary motor 10 is used to drive the corresponding separation semi-ring 601 to rotate horizontally. The three sets of rotary motors 10 are fixedly connected to the corresponding first mounting post 801, second mounting post 802 and third mounting post 803 through connecting posts 12.

[0034] like Figure 3 As shown, there are two sets of limiting slide grooves 5, which are fixedly installed on the processing table 1 in the vertical direction. The limiting slide groove 5 includes an arc-shaped half-groove 501 and a straight groove 502. The slider 303 slides back and forth along the sliding groove, which drives the connecting column 12 and the corresponding connecting separation half-ring 601 to move back and forth along the limiting slide groove 5. The connection between the arc-shaped half-groove 501 and the straight groove 502 is provided with a guide block 503 that limits the one-way sliding of the connecting column 12.

[0035] Two sets of screw assemblies are installed inside the separation semi-ring 601, and the four sets of screw assemblies drive the corresponding four component modules 704 inside the separation structure 6 to demold.

[0036] Specifically, this invention utilizes a separation structure 6 composed of two sets of separating semi-rings 601. The two sets of separating semi-rings 601 are operated independently by components on two sets of operating tables 3 on the processing table 1. The invention is described with the first mold 701, the second mold 702, and the third mold 703 arranged horizontally from left to right. The separating semi-rings 601 on the outer sides of the first mold 701, the second mold 702, and the third mold 703 are fixedly connected to the corresponding first mounting posts 801, the second mounting posts 802, and the third mounting posts 803. The first mounting post 801 is the shortest, and the lengths of the second mounting posts 802 and the third mounting posts 803 increase sequentially. The first mold 701 and the second mold 702 abut against each other, and their interiors are connected, forming a horizontally hinged injection cavity. The injection molding machine 9 then injects material into this cavity. After molding is completed, the slider 303 connected by the first mounting post 801 slides along the corresponding sliding groove, and the connecting post 12 cooperates with the limiting sliding groove 5 to drive the two sets of separating half rings 601 away, and slides by the arc-shaped half groove 501, so that the first mold 701 slides to the rear side of the third mold 703. At the same time, during the sliding of the separating half ring 601, the first mold 701 is driven to rotate 180° by the rotary motor 10. At the same time, the second mold 702 and the third mold 703 move forward synchronously, thus forming the second mold 702, the third mold 703 and the first mold 701 arranged in a horizontal direction from left to right. At this time, the interior of the second mold 702 and the third mold is connected to form a vertical hinge injection cavity. The injection molding machine 9 then injects into this injection cavity. After the injection is completed, the above operation is repeated to realize the staggered connection of the horizontal chain links and the vertical chain links in the chain link. The length of the chain link can be flexibly adjusted.

[0037] In this invention, by sequentially adjusting and aligning the positions of the first mold 701, the second mold 702, and the third mold 703, the injection molding requirements of the horizontal and vertical chain links can be completed in sequence. During injection molding, the corresponding injection cavity is in a closed state, which ensures the quality of injection molding. The injection-molded chain links are collected by the collection box 2.

[0038] Meanwhile, by designing a limiting slide groove 5, the present invention enables a rotary motor 10 to drive the corresponding separating half-ring 601 to rotate 180° when the connecting column 12 moves to the top of the arc of the limiting slide groove 5, so that the separating half-ring 601 can be adjusted by rotation with sufficient space.

[0039] like Figure 2As shown, in this embodiment of the invention, an electric sliding track 301 is installed in the sliding groove, and the slider 303 is fixedly connected to the electric slider 302 in the electric sliding track 301. The electric slider 302 slides and drives the slider 303 to slide synchronously. In this invention, three sets of electric sliders 302 drive the corresponding sliders 303 to slide, and the positions of the first mold 701, the second mold 702 and the third mold 703 are alternately switched.

[0040] like Figure 3 As shown, in this embodiment of the invention, the guide block 503 is slidably installed at the connecting hole at the corner of the limiting groove 5, and is elastically connected to the fixing block on the outer wall of the limiting groove 5 by a helical spring 504. In this invention, a set of guide blocks 503 is provided at the two corner posts of the arc-shaped half groove 501 and the straight groove 502. When the connecting post 12 slides, the guide block 503 is pressed into the connecting hole under the force. After the connecting post 12 slides past the guide block 503, the guide block 503 is supported by the helical spring 504 and extends out of the connecting hole, and guides and limits the connecting post 12.

[0041] like Figure 8 As shown, in this embodiment of the invention, an installation frame 602 is fixedly installed inside the separating half-ring 601, and a positioning rod 603 is provided on the outside of the sub-module 704. The positioning rod 603 is slidably connected to the low hole on the installation frame 602. The positioning rod 603 limits and guides the sliding of the sub-module 704, thereby improving the stability of the sub-module 704 when it is demolded.

[0042] Furthermore, the screw assembly includes a fixed screw 604, which is fixedly installed on the outside of the sub-module 704 and forms a helical pair transmission with the swivel nuts 605 rotatably installed on the mounting frame 602. The two sets of swivel nuts 605 are driven to rotate synchronously by a power component on the mounting frame 602. The power component includes a dual-head synchronous motor 606. The swivel shafts at both ends of the dual-head synchronous motor 606 form a helical pair transmission with the corresponding swivel nuts 605 through a bevel gear set 607. The dual-head synchronous motor 606 drives the two sets of swivel nuts 605 to rotate synchronously, which, in conjunction with the fixed screw 604, drives the sub-module 704 to move linearly.

[0043] The bevel gear set 607 includes two sets of transmission bevel gears. The two sets of transmission bevel gears are coaxially fixed to the outer side of the output shaft of the dual-head synchronous motor 606 and the slewing nut 605, and are meshed together.

[0044] Of course, other components with synchronous transmission capabilities can also be selected for the power components, such as a transmission belt transmission structure, etc.

[0045] like Figure 3 and Figure 7As shown, in this embodiment of the invention, the connecting column 12 is provided with a limiting ring 11 for sliding connection limiting groove 5, and the limiting ring 11 improves the sliding stability of the connecting column 12 along the limiting groove 5.

[0046] In summary, this invention designs an injection molding module 7, an injection molder 9, a separation structure 6, and limiting grooves 5. The injection molding module 7 includes a first mold 701, a second mold 702, and a third mold 703, which are installed in the corresponding separation structure 6. Two sets of limiting grooves 5 are fixedly installed vertically on the processing table 1. The limiting grooves 5 include arc-shaped semi-grooves 501 and straight grooves 502. During the injection molding process, the positions of the first mold 701, the second mold 702, and the third mold 703 can be sequentially interchanged to sequentially complete the injection molding requirements of horizontal and vertical chain links. Furthermore, the corresponding injection cavity is in a closed state during injection molding, ensuring the quality of the injection molding. This solves the problem that existing methods require customized injection molds for different lengths of polymer chain links, and the length of polymer chain links cannot be flexibly processed and manufactured according to actual requirements.

[0047] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
