Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an independent injection device. Background Technology

[0002] Most existing injection molding machines have their injection units designed together with the machine base. The existing injection molding machine structure consists of a clamping mechanism, frame, control system, and injection unit. This integrated design allows for better operation when the required actions are performed.

[0003] When producing two-color or other injection molded products, the integrated design requires the purchase of new machines or the addition of injection devices if the production process changes. However, there are many problems with adding ordinary injection devices, such as insufficient precision in controlling parameters such as injection volume, injection speed, and injection pressure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an independent injection device to solve the problems mentioned in the background technology. This utility model has a novel structure. When changing products or production processes, only the independent injection table needs to be adjusted, which shortens the production preparation time and improves production efficiency. When producing two-color products, it can be combined with other types of machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an independent injection device includes a base, a control box fixed to one side of the base, a frame fixed to the top of the base, an injection chamber on the top of the frame, a connection port at the upper end of the injection chamber, an injection cylinder fixed to one horizontal end of the injection chamber, an injection head fixed to the outer end of the injection cylinder, a cover covering the top of the outer end of the injection cylinder, the cover fixed to the injection chamber, mounting seats at both ends of the frame, and sliding grooves on the inner side of the mounting seats, the two ends of the injection chamber slidably mounted in the sliding grooves of the mounting seats, a cleaning component installed at the front end of the injection cylinder, the cleaning component including a toothed ring, the toothed ring being sleeved on the outer side of the front end of the cover, connecting rods slidably inserted into the two sides of the toothed ring, and semi-circular covers installed at the outer ends of the connecting rods, the two covers covering the injection head.

[0006] Furthermore, a screw is rotatably mounted laterally inside the frame via a bearing. A screw block is threaded onto the surface of the screw. The screw block slides along the top of the base. A mounting hole is provided on the top of the screw block, and the screw block is fixedly connected to the bottom of the injection molding machine housing through a vertical rod installed in the mounting hole.

[0007] Furthermore, a handwheel is rotatably mounted on one side of the frame at the top of the screw, and a gear transmission device is installed between the handwheel and the screw.

[0008] Furthermore, hydraulic cylinders are fixed at both ends of the frame at the bottom of the mounting base, and the extended ends of the hydraulic cylinders are fixedly connected to the mounting base. A support frame is fixed inside the mounting base, and the bottom of the injection molding machine box slides along the upper end of the support frame.

[0009] Furthermore, the cleaning assembly also includes a drive gear, the top of the gear ring is meshed with the drive gear, the top of the cover is fixed with a drive motor corresponding to the position of the drive gear, and the output end of the drive motor is fixedly connected to the drive gear.

[0010] Furthermore, a limiting frame is fixed on the outer wall of the corner of the cover, and the inner side of the toothed ring slides along the inside of the limiting frame.

[0011] Furthermore, the rear end of the toothed ring is provided with an arc frame, and two sliders are symmetrically slidably connected inside the arc frame. The sliders are fixedly connected to the connecting rod. The cover is fixed with electric push rods on the back of both ends of the arc frame, and the extended ends of the electric push rods are fixedly connected to the arc frame.

[0012] Furthermore, a connecting plate is rotatably mounted on one end of the connecting rod facing the cover, and the connecting plate is fixedly connected to the semi-circular cover. A motor is fixedly mounted on the outside of the connecting plate on the connecting rod, and the output end of the motor is fixedly connected to the rotatable connection point of the connecting plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses an electric push rod to push the arc frame to slide along the outer end of the cover. The connecting rod moves towards the injection head through the toothed ring. At this time, the two wrapping covers are located at the outer end of the connecting rod. After moving past the position of the injection head, the motor drives the connecting plate to rotate, rotating the wrapping covers to the side of the injection head. The two semi-circular wrapping covers merge into a whole cylinder to wrap the injection head. Then, the drive motor is turned on to drive the drive gear to rotate. The drive gear meshes with the toothed ring to drive the connecting rod and the wrapping covers to rotate around the injection head, cleaning the residual material on the surface and outer end of the injection head.

[0015] 2. When cleaning the injection head is not required, this utility model can also use two covers to wrap and protect the injection head. After cleaning, the covers are moved outward to facilitate rotation of the covers to face outward. Then, the motor drives the connecting plate and the covers to rotate outward, and the electric push rod retracts the covers to avoid interfering with the next use of the injection head. During the rotation of the connecting rod, it is not necessary to maintain a connection with the arc frame, so the slide can slide out along the openings at both ends of the arc frame. After cleaning, the slide returns to the inside of the arc frame, making it easy to store it backward with the arc frame.

[0016] 3. This utility model, through an independent hydraulic and electronic control integrated system, can independently control the injection volume, injection speed, and injection pressure of the injection station. The frame located at the bottom of the injection machine can adjust the left and right and up and down movement of the injection head, making it convenient for use with different equipment.

[0017] 4. Compared with the prior art, this utility model only requires adjustment of the independent injection station when changing products or production processes, which shortens the production preparation time, improves production efficiency, and can be used in combination with other types of machines when producing two-color products.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5This utility model provides a technical solution: an independent injection device, including a base 1, a control box 11 fixed to one side of the base 1, a frame 2 fixed to the top of the base 1, an injection chamber 3 on the top of the frame 2, a connection port at the upper end of the injection chamber 3, and an injection cylinder 32 fixed to one horizontal end of the injection chamber 3. An injection head 33 is fixed to the outer end of the injection cylinder 32, and a cover 31 is wrapped around the top of the outer end of the injection cylinder 32. The cover 31 is fixed to the injection chamber 3. Mounting seats 4 are provided at both ends of the frame 2, and sliding grooves are provided on the inner side of the mounting seats 4. The two ends of the injection chamber 3 are slidably installed in the sliding grooves of the mounting seats 4. The injection cylinder 3... The front end of the 2 is equipped with a cleaning component 5, which includes a toothed ring 53. The toothed ring 53 is sleeved on the outer front end of the cover 31. Connecting rods 54 are slidably inserted into the two sides of the toothed ring 53. Semi-circular wrapping covers 57 are installed on the outer ends of the connecting rods 54. The two wrapping covers 57 wrap around the injection head 33. When using the device, the horizontal and vertical positions of the injection machine box 3 are adjusted by the screw 21 and the mounting seat 4 in the frame 2. After each use, the injection head 33 is cleaned by the cleaning component 5 to remove the residual material from the injection head 33. The injection volume, injection speed and injection pressure of the injection station can be controlled independently by the independent hydraulic and electrical control integrated system of the control box 11.

[0026] In this embodiment, a screw 21 is rotatably mounted laterally inside the frame 2 via a bearing. A screw block 22 is threaded onto the surface of the screw 21. The screw block 22 slides along the top of the base 1. A mounting hole is provided on the top of the screw block 22, and the screw block 22 is fixedly connected to the bottom of the injection machine housing 3 through a vertical rod installed in the mounting hole. A handwheel 23 is rotatably mounted on one side of the frame 2 at the top of the screw 21, and a gear transmission device 24 is installed between the handwheel 23 and the screw 21. The gear transmission device 24 is a transmission of at least two gears meshing. The transmission effect is achieved by the rotation of the handwheel 23 at the outer end meshing with the gear on the screw 21, which avoids the problem of inconvenient arrangement of the handwheel 23. When the screw 21 rotates, the screw block 22 cooperates with the screw 21 to drive the injection machine housing 3 to move laterally, thereby adjusting the position of the injection head 33 laterally.

[0027] In this embodiment, hydraulic cylinders 41 are fixed at both ends of the frame 2 at the bottom of the mounting base 4, and the extended ends of the hydraulic cylinders 41 are fixedly connected to the mounting base 4. A support frame 42 is fixed inside the mounting base 4, and the bottom of the injection machine housing 3 slides along the upper end of the support frame 42. The height of the injection machine housing 3 and the injection head 33 can be adjusted by driving the mounting base 4 and the support frame 42 to move up and down through the hydraulic cylinders 41. The sliding connection between the injection machine housing 3 and the mounting base 4 and the support frame 42 is a common sliding rail connection, which is not shown in the figure.

[0028] In this embodiment, the cleaning component 5 further includes a drive gear 52. The top of the gear ring 53 is meshed with the drive gear 52. A drive motor 51 is fixedly mounted on the top of the cover 31 corresponding to the position of the drive gear 52, and the output end of the drive motor 51 is fixedly connected to the drive gear 52. A limit frame 510 is fixed on the outer wall of the corner of the cover 31, and the inner side of the gear ring 53 slides along the inside of the limit frame 510. An arc frame 55 is provided at the rear end of the gear ring 53. Two sliders 511 are symmetrically slidably connected inside the arc frame 55. The sliders 511 are fixedly connected to the connecting rod 54. The cover 31 is located in the arc frame 55. Electric push rods 56 are fixed to the back of both ends of the frame 55, and the extended ends of the electric push rods 56 are fixedly connected to the arc frame 55. A connecting plate 58 is rotatably mounted on the end of the connecting rod 54 facing the cover 57, and the connecting plate 58 is fixedly connected to the semi-circular cover 57. A motor 59 is fixed on the outside of the connecting rod 54 and the output end of the motor 59 is fixedly connected to the rotatable connection of the connecting plate 58. The cleaning component 5 can be installed in advance at the front end of the syringe 32, or it can be installed after each use. When cleaning the injection head 33 after injection, the electric push rod 56 is used to push the syringe head 33. The arc frame 55 slides along the outer end of the cover 31, and the connecting rod 54 moves towards the injection head 33 through the gear ring 53. At this time, the two wrapping covers 57 are located at the outer end of the connecting rod 54. After moving past the position of the injection head 33, the motor 59 drives the connecting plate 58 to rotate, rotating the wrapping covers 57 to one side of the injection head 33. The two semi-circular wrapping covers 57 merge into a whole cylinder to wrap the injection head 33. Then, the drive motor 51 is turned on to drive the drive gear 52 to rotate. The drive gear 52 meshes with the gear ring 53 to drive the connecting rod 54 and the wrapping covers 57 to rotate around the injection head 33, cleaning the residual material on the surface and outer end of the injection head 33. In practice, when cleaning the injection head 33 is not required, the two covers 57 can be used to wrap and protect the injection head 33. After cleaning, the covers 57 are moved outward to facilitate rotation of the covers 57 to face outward. Then, the motor 59 drives the connecting plate 58 and the covers 57 to rotate outward. The electric push rod 56 retracts the covers 57 to avoid interfering with the next use of the injection head 33. During the rotation of the connecting rod 54, it is not necessary to maintain a connection with the arc frame 55, so the slide can slide out along the openings at both ends of the arc frame 55. After cleaning, the slider 511 returns to the inside of the arc frame 55 for easy storage along with the arc frame 55.

[0029] When using the device, the handwheel 23 at the outer end rotates and meshes with the gear on the screw 21 to achieve the transmission effect, which avoids the problem of inconvenient placement of the handwheel 23. When the screw 21 rotates, the screw block 22 cooperates with the screw 21 to drive the injection machine housing 3 to move laterally, thereby adjusting the position of the injection head 33 laterally. The height of the injection machine housing 3 and the injection head 33 can be adjusted by lifting and lowering the mounting base 4 and the support frame 42 driven by the hydraulic cylinder 41. After each use, when cleaning the injection head 33 after injection, first push the arc frame 55 along the outer end of the cover 31 with the electric push rod 56, and the connecting rod 54 moves towards the injection head 33 through the gear ring 53. At this time, the two wrapping covers 57 are located at the outer end of the connecting rod 54. After moving past the position of the injection head 33, the motor 59 drives the connecting plate 58 to rotate, rotating the wrapping covers 57 to the side of the injection head 33, and the two semi-circular wrapping covers 57 merge into a whole cylinder to wrap the injection head 33. Then the drive is turned on. The motor 51 drives the drive gear 52 to rotate. The drive gear 52 meshes with the gear ring 53, causing the connecting rod 54 and the cover 57 to rotate around the injection head 33, cleaning the residual material on the surface and outer end of the injection head 33. When cleaning the injection head 33 is not required, the two covers 57 can be used to cover and protect the injection head 33. After cleaning, the covers 57 are moved outward to facilitate rotation of the covers 57 to face outward. Then the motor 59 drives the connecting plate 58 and the covers 57 to rotate outward. The electric push rod 56 retracts the covers 57 to avoid interfering with the next use of the injection head 33. During the rotation of the connecting rod 54, it does not need to maintain a connection with the arc frame 55, so the slide can slide out along the openings at both ends of the arc frame 55. After cleaning, the slider 511 returns to the inside of the arc frame 55 for easy retraction along with the arc frame 55. Through the independent hydraulic and electrical control integrated system of the control box 11, the injection volume, injection speed, and injection pressure of the injection station can be controlled independently.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
