Description

Technical Field

[0001] This invention relates to the field of injection molding technology, specifically to an injection molding machine for processing rubber products that facilitates material loading. Background Technology

[0002] Rubber product manufacturing involves producing various rubber products using natural and synthetic rubber as raw materials. It also includes rubber products manufactured from recycled waste rubber. The processing steps for rubber products include raw material preparation, mixing, molding, and vulcanization. Injection molding is indispensable in this process. Injection molding machines can quickly inject the mixed rubber material into the mold, and precise temperature, pressure, and injection speed control ensures high levels of dimensional accuracy, density uniformity, and surface quality, reducing product defects and scrap rates. However, the characteristics of rubber products necessitate precise control during the injection molding process. Different types and formulations of rubber materials may have different flowability, shrinkage rates, and vulcanization characteristics. Therefore, after completing the injection of one mold, it is necessary to wait for the mold to cool naturally before proceeding to the next injection operation. Furthermore, after completing the injection of one mold, the injection molding machine must wait for the current mold to complete injection, holding pressure, cooling, and product removal before proceeding to the next injection operation. Therefore, each step requires separate processing. Because it cannot quickly switch to the next mold, this process results in significant time waste and affects the injection molding machine's efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an injection molding machine for processing rubber products that facilitates material loading, thereby overcoming the aforementioned shortcomings in the technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an injection molding machine for processing rubber products with convenient material loading, comprising a frame, molds, and an injection head. A feed chute is installed at the top of the injection head, facilitating the loading of rubber products. A telescopic cylinder is connected between the frame and the injection head. A moving component is installed between the frame and the injection head, enabling multiple molds to complete simultaneous injection and cooling operations with the injection head, allowing the molds to move along the bottom of the injection head for rotation. The moving component includes a support platform rotatably connected between the frame and the injection head, and a rotary table connected to the top of the support platform. A first servo motor is connected between the frame and the support platform. The top of the rotary table has several placement slots for placing molds, and these slots remain open on the rotary table. The rotary table is used to move the molds in the same direction along the bottom of the injection head, ensuring accurate injection of material from the telescopic cylinder into the molds. A mold-restricting frame is fixedly connected inside each placement slot, and the frame is equipped with a mechanism for releasing or locking the molds. A tight centering assembly is used to maintain the stability of the injection molded model and to allow the molded model to loosen and lock during movement. A concentric assembly is provided between the placement slot and the support platform, which allows the centering assembly to cooperate with the support platform so that the centering assembly rotates relative to the support platform when the support platform rotates in the same direction. A side insertion assembly is provided between the injection head and the centering assembly, which is used to abut the mold and the injection head against each other after the injection head contacts the model. In addition, several models on the rotary table are kept in a suitable position relative to the injection head to prevent the molded model from getting too close to the injection head during movement. This allows the models to have good natural cooling on the rotary table, improving the injection quality of the injection molding machine. The number of placement racks and placement slots is the same as the number of models, which facilitates continuous injection operation between the models and the injection head, realizes cyclic operation of different stations, reduces the idle time of the equipment, and allows the process of each station to be switched once with each rotation of the rotary table, so as to carry out continuous production.

[0005] Preferably, the centering assembly includes two limiting frames symmetrically connected to the placement frame and a stabilizing platform rotatably connected within the placement frame. The top of the placement frame has a displacement groove communicating with its interior for the movement of the two limiting frames. The bottom ends of the two limiting frames are fixedly connected to two base plates, and the top ends of the two base plates are connected to two connecting columns. Two displacement plates are movably sleeved on the outside of the two connecting columns. The top of the stabilizing platform is symmetrically connected to centering columns for the two displacement plates to fit onto. Furthermore, during the model clamping process, the limiting frames cooperate with the support platform and the rotating platform, causing the support platform and the rotating platform to rotate in the same direction, thereby causing the model to move along the injection molding path. The head moves downwards to complete the rotation operation. During this reciprocating movement, the limiting frame and the model are repeatedly released and locked, ensuring the positional accuracy of the limiting frame during each release and locking of the model. This guarantees a high degree of repeatability in the model's position on the placement frame, ensuring that the model is in the correct position after each rotation and locking, reducing problems such as product size deviation and shape defects caused by inaccurate positioning. In addition, the limiting frame can release and lock the model during the rotation of the rotary table, enabling rapid model replacement, reducing downtime, improving production efficiency, and ensuring the continuity of the production process.

[0006] Preferably, the bottom end of the base plate is also fixedly connected to an directional sleeve, the inside of the placement frame is fixedly connected to an directional rod for the directional sleeve to move, a centering sleeve is fixedly connected to the side of the placement frame near the directional rod, the bottom end of the stabilizing platform is connected to a rotating column, and the bottom end of the rotating column passes through the centering sleeve; and the directional rod is horizontally installed inside the placement frame, so that the directional sleeve moves along the external guide of the directional rod, ensuring the stable movement of the limiting frame.

[0007] Preferably, the model and the injection head are combined to form an I-shaped structure, the limiting frame is set as a W-shaped structure, and the limiting frame is stably attached to the model and the injection head; and part of the limiting frame can remain attached to the model, and after the limiting frame is attached to the model, the injection head can still move along one side of the limiting frame, so that the limiting frame is attached to the model and the injection head.

[0008] Preferably, the concentric assembly includes a support plate frame installed at the bottom of the rotary table, the bottom end of the rotating column passes through the rotary table and is rotatably connected to the top of the support plate, a second gear is sleeved on the outside of the rotating column, a second servo motor is fixedly connected to the bottom of the rotary table, and one end of the second servo motor passes through the support plate frame and is connected to a first gear meshing with the second gear; and the meshing transmission between the first gear and the second gear is beneficial to ensure that the model is subjected to uniform force during the process of the frame releasing and locking the model, avoiding uneven wear of the model due to uneven local force, extending the service life of the model, and ensuring that the quality of the product is not affected.

[0009] Preferably, the rotating platform and the support platform are externally fitted with a limiting ring, and a fixed arc block is fixedly connected to the outside of the limiting ring. An arc plate is fixedly connected to one side of the fixed arc block, and the arc plate is attached to the outside of the rotating platform. The arc plate is used to temporarily close the open placement slot, and when the arc plate moves along the outside of the rotating platform, the placement frame and the placement slot, it is used to abut against the outside of the model, and to position and install the model at the top of the placement frame. The number of arc plates is the same as the number of placement slots, and the arc plates can also indicate the position of the model between the placement frame and the limiting frame, ensuring that the limiting frame remains stable when the model is loosened and locked, and ensuring that the limiting frame always firmly locks the model during the rotation of the rotating platform.

[0010] Preferably, the side insertion assembly includes a side ear plate fixedly connected to the outside of the injection head and an extrusion plate installed on the side of the limiting frame near the injection head. The extrusion plate is used to maintain stable contact between the injection head and the limiting frame. A movable cavity is opened on one side of the limiting frame, and a movable cone is slidably connected inside the movable cavity. One end of the movable cone is fixedly connected to one side of the extrusion plate. One side of the side ear plate is set with an inclined structure, and the side of the movable cone corresponding to the side ear plate is also set with an inclined structure. The movable cone and the side ear plate are sloped together. The extrusion plate keeps the outside of the injection head against the side of the limiting frame, thereby maintaining precise positioning of the injection head and the mold during the injection stage, ensuring that the relative position of the injection head and the mold cavity is always accurate.

[0011] Preferably, an abutment ring is also sleeved on the outside of the movable cone, and a spring is connected between the movable cavity and the abutment ring. The spring is sleeved on the outside of the movable cone and is used to push the movable cone to move and reset. The movable cone moves inside the movable cavity, causing the abutment ring to move synchronously. Then, the abutment ring pushes the spring under the movement, so that the spring is squeezed inside the abutment ring and the movable cavity.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0013] 1. By setting up the moving components, the model and the injection head, this invention not only facilitates the rapid feeding of materials in the feeding trough, but also enables rapid switching between the model and the injection head, allowing the model and the injection head to complete the injection and cooling operations on one side while the other side is being cooled. Each step does not require separate processing, enabling cyclical operation of different workstations. This process will not cause a lot of time waste and improves the injection molding efficiency of the injection molding machine.

[0014] 2. This invention, through the arrangement of a centering component, a rotating platform, a model, and an injection head, enables the model to be released and locked during the rotation of the rotating platform, achieving rapid model replacement or observation of the model's movement status. Simultaneously, while the rotating platform releases and locks the model during rotation, a limiting frame clamps the model, allowing the support platform, rotating platform, and limiting frame to work together. This facilitates the support platform and rotating platform rotating in the same direction, and then the model moves along the underside of the injection head to complete the rotation operation. At this time, during the reciprocating movement of the model, the limiting frame and the model reciprocate to release and lock, ensuring the positional accuracy of the limiting frame during each release and lock of the model. This ensures that the model's position on the placement frame has high repeatability, guaranteeing that the model is in an accurate position after each rotation and lock, reducing problems such as product size deviation and shape defects caused by inaccurate positioning.

[0015] 3. By setting up concentric components, a limiting frame, a model, an injection head, and a rotary table, this invention enables the limiting frame to apply uniform force to the model during the process of releasing and locking the model. This avoids uneven wear of the model due to uneven local force, extends the service life of the model, and ensures that the quality of the product is not affected.

[0016] 4. By setting up the arc plate, placement groove, rotary table, placement frame and model, the present invention can ensure that the arc plate can reliably lock the model and the limiting frame after moving, ensuring that the model will not be displaced due to loosening during injection molding, which helps to maintain stable injection between the injection head and the model.

[0017] 5. By setting up the side insertion component, model, injection head and limiting frame, the present invention can achieve precise positioning of the injection head and model during the injection stage, ensuring that the relative position of the injection head and the model cavity is always accurate.

[0018] 6. By setting up a limiting frame, a model, and an injection head, the present invention enables the limiting frame to be pre-fitted to the outside of the model, and then the other part of the limiting frame to contact the outside of the injection head. Thus, even when the model is restricted, the injection head can still contact the model, ensuring stable injection between the injection head and the model. Attached Figure Description

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] This invention provides, for example Figures 1-4 The injection molding machine shown is for easy loading of rubber products. It includes a frame 1, a mold 14 and an injection head 11. The top of the injection head 11 is equipped with a feed groove 12, which facilitates the loading of rubber products. A telescopic cylinder 13 is connected between the frame 1 and the injection head 11. A moving component 2 is installed between the frame 1 and the injection head 11. The moving component 2 can realize the operation of injection molding and cooling on one side of several molds 14 and the injection head 11, so that the molds 14 can move along the bottom of the injection head 11 to complete the rotation operation.

[0039] The moving component 2 includes a support platform 24 rotatably connected between the frame 1 and the injection head 11, and a rotary table 21 connected to the top of the support platform 24. A first servo motor 25 is connected between the frame 1 and the support platform 24. The top of the rotary table 21 has several placement slots 22 for placing the model 14, and the placement slots 22 are kept open on the rotary table 21. The rotary table 21 is used to move the model 14 in the same direction along the downward direction of the injection head 11 to ensure that the material in the telescopic cylinder 13 is accurately injected into the model 14. A placement rack 23 for restricting the model 14 is fixedly connected inside the placement slot 22. The placement rack 23 is provided with a support for holding the model 14. 4. A centering component 3 is provided for loosening or locking, and the centering component 3 is used to maintain additional stability of the injection molded model 14 and to loosen and lock the model 14 during movement after injection. A concentric component 4 is provided between the placement groove 22 and the support platform 24, and the concentric component 4 is used to enable the centering component 3 and the support platform 24 to cooperate, so that the centering component 3 rotates relative to the support platform 24 when the support platform 24 rotates in the same direction. A side insertion component 5 is provided between the injection head 11 and the centering component 3, and the side insertion component 5 is used to make the model 14 and the injection head 11 abut against each other immediately after the injection head 11 contacts the model 14.

[0040] When the injection head 11 injects its internal material into the mold 14, the telescopic cylinder 13 extends and retracts, pushing the injection head 11 downward along one side of the frame 1. As the injection head 11 moves downward, its end is aligned with the mold 14. Then, the feed chute 12 feeds its internal rubber product into the frame 1, allowing the injection head 11 to inject its internal rubber product into the mold 14, ensuring the processing quality of the rubber product. The first servo motor 25 drives the support platform 24 and the rotary table 21 to rotate along the frame 1. The rotary table 21 then rotates, causing the placement chute 22, the placement rack 23, and the mold 14 to rotate synchronously. At this time, the mold 14 moves below the injection head 11 under the rotation of the rotary table 21. After injection, the mold 14 moves away from below the injection head 11, and one of the molds 14 moves closer to below the injection head 11. Thus, several molds 14 and the injection head 11 complete the injection and cooling process on one side, allowing the molds 14 to move below the injection head 11 to complete the rotation operation.

[0041] refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the centering assembly 3 includes two limiting frames 35 symmetrically connected to the placement frame 23 and a stabilizing platform 33 rotatably connected inside the placement frame 23. The top of the placement frame 23 has a displacement groove 31 communicating with its interior to allow the two limiting frames 35 to move. The bottom ends of the two limiting frames 35 are fixedly connected to two base plates 34. The top ends of the two base plates 34 are connected to two connecting columns 37. Two displacement plates 36 are movably sleeved on the outside of the two connecting columns 37. The top of the stabilizing platform 33 is symmetrically connected to centering columns for the two displacement plates 36 to be sleeved on. 38; The bottom end of the base plate 34 is also fixedly connected to the directional sleeve 301. The inside of the placement frame 23 is fixedly connected to the directional rod 39 for the directional sleeve 301 to fit and move. The side of the placement frame 23 near the directional rod 39 is fixedly connected to the centering sleeve 302. The bottom end of the stabilizing platform 33 is connected to the rotating column 32, and the bottom end of the rotating column 32 passes through the centering sleeve 302. The model 14 and the injection head 11 are combined to form an I-shaped structure. The limiting frame 35 is set as a W-shaped structure, and the limiting frame 35 is stably attached to the model 14 and the injection head 11.

[0042] When the injection head 11 continuously injects molding material into the model 14, and the model 14 moves along the bottom of the injection head 11 to complete the rotation operation, the rotation of the stabilizing platform 33 drives the two centering columns 38 to rotate simultaneously. The rotation of the two centering columns 38 then pulls the two displacement plates 36 to move towards or relative to each other. At this time, the two displacement plates 36 rotate along the outside of the two connecting columns 37 and pull the two connecting columns 37 to move towards or relative to each other. Furthermore, the movement of the two connecting columns 37 towards each other pulls the two base plates 34 to move synchronously towards each other. During the movement, the base plates 34 also drive the directional sleeve 301 to move simultaneously. Subsequently, the interior of the directional sleeve 301 moves along the outside of the directional rod 39. At this time, the directional sleeve 301 moves within the placement frame 23 to ensure stable contact between the limiting frame 35 and the model 14. As a result, the two base plates 34 move, causing the two limiting frames 35 to move closer to the outside of the model 14, so that part of the limiting frame 35 is in contact with the outside of the model 14. Then, the injection head 11 moves downward and contacts the model 14. Subsequently, the other part of the limiting frame 35 contacts the outside of the injection head 11. Thus, even when the model 14 is restricted, the injection head 11 can still contact the model 14, ensuring precise contact between the injection head 11 and the model 14 and ensuring stable injection between the injection head 11 and the model 14.

[0043] refer to Figures 5-8 As shown, the concentric component 4 includes a support plate frame 42 installed at the bottom of the rotary table 21, the bottom end of the rotating column 32 passing through the rotary table 21 and rotatably connected to the top of the support plate 24, a second gear 44 sleeved on the outside of the rotating column 32, a second servo motor 41 fixedly connected to the bottom of the rotary table 21, and one end of the second servo motor 41 passing through the support plate frame 42 and connected to a first gear 43 meshing with the second gear 44; a limiting ring 47 is rotatably sleeved on the outside of the rotary table 21 and the support plate 24, a fixed arc block 45 is fixedly connected to the outside of the limiting ring 47, an arc plate 46 is fixedly connected to one side of the fixed arc block 45, and the arc plate 46 is attached to the outside of the rotary table 21. The arc plate 46 is used to temporarily close the open placement slot 22, and when the arc plate 46 moves along the outside of the rotary table 21, the placement frame 23 and the placement slot 22, it is used to abut against the outside of the model 14, and to position and install the model 14 at the top of the placement frame 23.

[0044] When the limiting frame 35 needs to be driven, the second servo motor 41 drives the first gear 43 to move circumferentially along the bottom end of the support plate frame 42. Then the first gear 43 rotates and meshes with the second gear 44. At this time, the second gear 44 rotates and drives the rotating column 32 to rotate within the rotary table 21, the support table 24 and the centering sleeve 302. At this time, the arc plate 46 is pushed to drive the fixed arc block 45 to move synchronously. Then the fixed arc block 45 moves and drives the limiting ring 47 to rotate outside the rotary table 21 and the support table 24. At this time, the arc plate 46 moves outside the rotary table 21, the placement frame 23 and the placement slot 22 to open or temporarily close the placement slot 22. This allows the arc plate 46 to reliably lock the model 14 and the limiting frame 35 after moving, ensuring that the model 14 will not be displaced due to loosening during the injection molding process. This helps to maintain stable injection between the injection head 11 and the model 14.

[0045] refer to Figures 8-11 As shown, the side insertion assembly 5 includes a side ear plate 56 fixedly connected to the outside of the injection head 11 and an extrusion plate 55 installed on the side of the limiting frame 35 near the injection head 11. The extrusion plate 55 is used to maintain stable contact between the injection head 11 and the limiting frame 35. A movable cavity 52 is provided on one side of the limiting frame 35. A movable cone 51 is slidably connected inside the movable cavity 52. ​​One end of the movable cone 51 is fixedly connected to one side of the extrusion plate 55. One side of the side ear plate 56 is set with an inclined structure. The side of the movable cone 51 corresponding to the side ear plate 56 is also set with an inclined structure. The movable cone 51 and the side ear plate 56 are sloped together. An abutment ring 53 is also sleeved on the outside of the movable cone 51. A spring 54 is connected between the movable cavity 52 and the abutment ring 53. The spring 54 is sleeved on the outside of the movable cone 51. The spring 54 is used to push the movable cone 51 to move and reset.

[0046] When the limiting frame 35 restricts the model 14 and the injection head 11 approaches the model 14, the downward movement of the injection head 11 causes the side ear plate 56 to move downward simultaneously. The inclined portion of the side ear plate 56 then contacts the inclined portion of the moving cone 51, generating a relative compressive force. This force pushes the moving cone 51 along the inside of the moving cavity 52 in the direction of the applied force. At this time, the movement of the moving cone 51 pushes the extrusion plate 55 along one side of the limiting frame 35 towards the outside of the injection head 11, and the movement of the moving cone 51 within the moving cavity 52 causes contact... The ring 53 moves synchronously, and then the abutment ring 53 pushes the spring 54 under the movement, so that the spring 54 is squeezed inside the abutment ring 53 and the moving cavity 52. ​​After the inclined end of the side ear plate 56 contacts the inclined end of the moving cone 51, and the side ear plate 56 maintains contact with the limiting frame 35, the extrusion plate 55 keeps in contact with the outside of the injection head 11 on one side of the limiting frame 35. Then the injection head 11 and the mold 14 maintain precise positioning during the injection stage, ensuring that the relative position of the injection head 11 and the mold 14 cavity is always accurate.

[0047] Working principle:

[0048] When using;

[0049] First, the concentric component 4 drives the rotating column 32 to rotate simultaneously. Then, the rotating column 32 rotates, causing the two centering columns 38 to rotate simultaneously. Subsequently, the two centering columns 38 rotate, pulling the two displacement plates 36 to move towards or relative to each other. At this time, the two displacement plates 36 rotate along the outside of the two connecting columns 37 and pull the two connecting columns 37 to move towards or relative to each other. This causes the two connecting columns 37 to move towards each other, pulling the two base plates 34 to move towards each other synchronously. As a result, the movement of the two base plates 34 causes the two limiting frames 35 to move closer to the outside of the model 14, so that part of the limiting frame 35 is in contact with the outside of the model 14.

[0050] After the model 14 is restricted on the placement rack 23 by the limiting frame 35, the first servo motor 25 drives the support platform 24 and the rotary table 21 to rotate along the frame 1. Then the rotary table 21 rotates, causing the placement slot 22, the placement rack 23 and the model 14 to rotate synchronously. At this time, the model 14 moves along the bottom of the injection head 11 under the rotation of the rotary table 21, and the model 14 after injection is away from the bottom of the injection head 11. One of the models 14 moves closer to the bottom of the injection head 11, so that several models 14 and the injection head 11 complete the injection on one side and cooling on the other side, so that the model 14 moves along the bottom of the injection head 11 to complete the rotation operation.

[0051] The rotation of the rotary table 21 causes the model 14 to be positioned below the injection head 11. At this time, the telescopic cylinder 13 extends and retracts, pushing the injection head 11 downward along one side of the frame 1. The downward movement of the injection head 11 causes the side ear plate 56 to move downward synchronously. Then, the inclined part of the side ear plate 56 contacts the inclined part of the moving cone 51 and generates a relative squeezing force, which pushes the moving cone 51 to move along the inside of the moving cavity 52 in the direction of the force. At this time, the moving cone 51 pushes the extrusion plate 55 to move closer to the outside of the injection head 11 along one side of the limiting frame 35. And the movement of the moving cone 51 inside the moving cavity 52 causes the contact ring 53 to move synchronously. The contact ring 53 pushes the spring 54 as it moves, causing the spring 54 to be squeezed inside the contact ring 53 and the moving cavity 52. ​​After the inclined end of the side ear plate 56 contacts the inclined end of the moving cone 51, and the side ear plate 56 maintains contact with the limiting frame 35, the extrusion plate 55 keeps in contact with the outside of the injection head 11 on one side of the limiting frame 35. As the injection head 11 moves downward, it keeps its end aligned with the mold 14. Then the feed chute 12 feeds the rubber product inside into the machine frame 1, so that the injection head 11 injects the rubber product inside into the mold 14, ensuring the processing quality of the rubber product.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
