Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to an injection molding device for the outer shell of a rat feeding box and its method of use. Background Technology

[0002] Injection molding equipment refers to specialized plastic molding machinery used to produce various types of box shells (such as home appliances, electronic instruments, and logistics boxes). It primarily uses the injection molding process to inject molten plastic raw materials into a precision mold cavity, which then cools and solidifies to form box shell products with specific structures and dimensional accuracy. This equipment typically consists of core components such as an injection system, a mold clamping system, a hydraulic and electrical control system, and mold tooling. It features high clamping force, large injection volume, precise temperature control, and automated operation capabilities. It is adaptable to different materials such as ABS, PP, and PC, and can efficiently produce complex structures, thin-walled boxes, or large box shells.

[0003] However, current injection molding equipment for rat cage shells requires unloading (demolding) the shell during injection molding. Since some injection molding equipment does not have an automatic unloading structure, manual unloading is still required, which is time-consuming and labor-intensive. When unloading the rat cage shell, workers often need to manually intervene to remove the workpiece, which involves workers entering the processing area and poses a safety risk.

[0004] Therefore, there is a need for an injection molding machine and its usage method for the outer shell of a rat feeding box to improve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an injection molding device for the outer shell of a rat feeding box and a method for using it, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An injection molding machine for the outer shell of a rat feeding box includes a machine frame, a controller mounted on the outer wall of the machine frame via guide posts, an injection molding assembly mounted on the outer wall of the machine frame, and a feeding assembly mounted on one side of the injection molding assembly and on the outer wall of the machine frame. A fixed support column is installed on the outer wall of the equipment frame. A top plate is installed on the outer wall of the fixed support column.

[0007] As a preferred embodiment of the present invention, the injection molding assembly includes a mounting plate and a fixing plate. Two sets of mounting plates are provided and are respectively located on the opposite outer walls of the equipment frame. An electrically controlled cylinder is installed on the outer wall of the mounting plate, and a clamping side plate is installed at one end of the electrically controlled cylinder. Two sets of fixing plates are provided and are respectively located on the opposite outer walls of the equipment frame. The fixing plate is located on one side of the mounting plate. A limit guide rod is installed on the opposite inner wall of the fixing plate, and an electrically controlled hydraulic cylinder is installed on the outer wall of the fixing plate.

[0008] As a preferred embodiment of the present invention, one end of the electro-hydraulic cylinder penetrates through the fixed plate and extends to the outer wall of the fixed plate, where a sealing outer plate is installed. A movable template is embedded in the inner wall of the sealing outer plate. A limit sleeve is installed on the outer wall of the sealing outer plate. A pull rod is slidably connected to the port of the limit sleeve. A baffle is installed on the outer wall of the limit sleeve. A limit spring is installed on the outer wall of the baffle, wherein the limit spring is located on one side of the pull rod.

[0009] As a preferred embodiment of the present invention, a static template is installed on the outer wall of the equipment frame, wherein the static template is located on one side of the moving template, and one end of the static template is embedded in the outer wall of the fixed plate. The connection between the static template and the fixed plate is a continuous structure. A sliding limiting plate is slidably connected on one side of the fixed plate and on the outer wall of the limiting guide rod. An guide rod is installed on the outer wall of the sliding limiting plate.

[0010] As a preferred embodiment of the present invention, one end of the guide rod passes through the fixed plate and extends to the inner wall of the static template, where an ejector plate is installed. The ejector plate and the static template are connected by a sliding connection. One end of the pull rod passes through the fixed plate and extends to the outer wall of the fixed plate, where a sliding limiting plate is connected. The pull rod and the fixed plate are connected by a sliding connection. A limiting spring is connected to the outer wall of the sliding limiting plate.

[0011] As a preferred embodiment of the present invention, the feeding assembly includes a mounting base, a contact sensor, and a storage bin. The mounting base is mounted on the inner wall of the equipment frame, and a guide plate is rotatably connected to the outer wall of the mounting base. A positioning block is mounted on the inner wall of the mounting base, and multiple sets of positioning blocks are provided and located on the inner wall of the mounting base respectively. An electrically controlled push cylinder is rotatably connected to the outer wall of the positioning block via a rotating rod, and one end of the electrically controlled push cylinder is rotatably connected to a limit block via a rotating rod.

[0012] As a preferred embodiment of the present invention, one end of the limiting block is connected to the bottom outer wall of the guide plate, the contact sensor is embedded in the port of the static template, the storage box is magnetically connected to the side wall of the equipment frame, a handle is installed on the side wall of the storage box, and a caster wheel is installed on the bottom outer wall of the storage box. Multiple sets of caster wheels are provided and are respectively located on the bottom outer wall of the storage box.

[0013] As a preferred embodiment of the present invention, a foot pad is provided at the bottom corner of the equipment frame, the stationary template is located directly below the pressing block, one end of the feeder is connected to the stationary template, and the controller is connected to the electrically controlled pressing cylinder, the feeder, the electrically controlled cylinder, the electrically controlled hydraulic cylinder, the electrically controlled pushing cylinder and the contact sensor via wires, and the connection method is electrical connection.

[0014] Through the above technical solution, the electrically controlled cylinder rotates on the outer wall of the rotating rod. At the same time, the other end of the electrically controlled cylinder pulls the limiting block through the rotating rod, which causes the limiting block to move the guide plate. This causes the guide plate to rotate downward and tilt on the outer wall of the mounting base. When the mold part moves out of the stationary template, it slides down the inclined guide plate into the storage box for storage. The inner cavity of the storage box is equipped with a buffer pad. When the mold part slides down, it is cushioned by the buffer pad to prevent the mold part from being bumped.

[0015] A method for using an injection molding machine for the outer shell of a rodent feeding box, the specific steps of which are as follows: Operation Step 1: Turn on the controller and preset parameters, and the controller will control the electric cylinder to operate. This will cause one end of the electric cylinder to push the clamping side plate to move towards the middle, thereby clamping and fixing the static template. At the same time, the controller will control one end of the electric pressing cylinder to push the fixed base downward through the pressing rod, thereby causing the fixed base to drive the pressing block to fix the static template. Operation Step Two: The controller controls the electro-hydraulic cylinder to operate, which in turn pushes the sealing outer plate to move laterally. This causes the sealing outer plate to move the moving template laterally. When the sealing outer plate moves laterally, it causes the limiting sleeve of the sealing outer plate to move laterally as well. This causes the limiting sleeve to move laterally on the outer wall of the pull rod. At the same time, the limiting sleeve compresses the limiting spring through the baffle, which in turn causes the pull rod to push the sliding limiting plate to move laterally. Simultaneously, the sliding limiting plate moves the ejector plate laterally through the guide rod, causing the ejector plate to move to the inner side of the static template cavity. Then, the moving template and the static template cooperate to facilitate injection molding. At the same time, the controller controls the feeder to inject the static template. Operation Step 3: After injection molding is completed, when the controller controls the electro-hydraulic cylinder to reset, one end of the electro-hydraulic cylinder will drive the sealing outer plate to move laterally to reset, which in turn will drive the limit sleeve to move laterally to reset. When the limit sleeve moves to the appropriate position, the limit spring will extend, which will drive the limit sleeve to move laterally, which will drive the pull rod to move laterally, which will drive the sliding limit plate to move laterally, so that the sliding limit plate will drive the ejector plate to move laterally via the guide rod, which will cause the ejector plate to move outward in the inner cavity of the stationary template, so that the ejector plate will eject the mold part from the inner cavity of the stationary template. Operation Step 4: The controller controls the electro-hydraulic cylinder to reset and move. At the same time, when the ejector plate pushes the mold part out of the stationary template, the contact sensor will generate an electrical signal when the mold part comes into contact with it. This signal is transmitted to the controller through the wire, which in turn controls the electro-hydraulic cylinder to rotate on the outer wall of the rotating rod. Meanwhile, the other end of the electro-hydraulic cylinder pulls the limit block through the rotating rod, which causes the limit block to move the guide plate. This causes the guide plate to rotate downward and tilt on the outer wall of the mounting base. When the mold part moves out of the stationary template, it will slide down the tilted guide plate into the storage box.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the mold part comes into contact with the contact sensor, the contact sensor generates an electrical signal, which is transmitted to the controller via a wire. The controller then controls the electrically controlled push cylinder to rotate on the outer wall of the rotating rod. Simultaneously, the other end of the electrically controlled push cylinder pulls the limit block via the rotating rod, causing the limit block to move the guide plate. This causes the guide plate to rotate downwards and tilt on the outer wall of the mounting base. When the mold part moves out of the stationary template, it slides down the tilted guide plate into the storage box for storage. This solves the problem that current injection molding equipment for rat breeding cage shells often requires manual intervention to remove the workpiece during unloading, which poses a safety risk as the worker's body enters the processing area.

[0017] 2. In this invention, the static template is fixed by a clamping side plate driven by an electrically controlled cylinder, while the electrically controlled pressing cylinder is fixed by a pressing block. Subsequently, the electrically controlled hydraulic cylinder pushes the sealing outer plate to move the moving template horizontally. During the sliding of the limiting sleeve along the pull rod, the limiting spring is compressed, and the sliding limiting plate and the ejector plate retract inward to the inner side of the static template. Material injection is completed through the feeder. When the limiting sleeve moves to the appropriate position, the limiting spring will extend, which will cause the limiting sleeve to move the pull rod laterally. This will cause the pull rod to move the sliding limiting plate laterally, so that the sliding limiting plate will move the ejector plate laterally via the guide rod. This will cause the ejector plate to move outward in the inner cavity of the static template, so that the ejector plate will eject the mold part from the inner cavity of the static template. This solves the problem that the current injection molding equipment for the outer shell of the rat breeding box does not have an automatic unloading structure and still requires manual unloading, which is time-consuming and labor-intensive.

A sealing outer plate 307 is installed thereon. A moving template 308 is embedded in the inner wall of the sealing outer plate 307. A limit sleeve 309 is installed on the outer wall of the sealing outer plate 307. A pull rod 310 is slidably connected at the end of the limit sleeve 309. A baffle 311 is installed on the outer wall of the limit sleeve 309. A limit spring 312 is installed on the outer wall of the baffle 311.

[0024] In this embodiment, the feeding assembly 4 includes a mounting base 401, a contact sensor 402, and a storage bin 403. The mounting base 401 is mounted on the inner wall of the equipment frame 1. A guide plate 404 is rotatably connected to the outer wall of the mounting base 401. A positioning block 405 is mounted on the inner wall of the mounting base 401. Multiple sets of positioning blocks 405 are provided and are respectively located on the inner wall of the mounting base 401. An electrically controlled push cylinder 407 is rotatably connected to the outer wall of the positioning block 405 via a rotating rod 406. One end of cylinder 407 is rotatably connected to limit block 409 via rotating rod 408. One end of limit block 409 is connected to the bottom outer wall of guide plate 404. Contact sensor 402 is embedded in the port of static template 313. Storage box 403 is magnetically connected to the side wall of equipment frame 1.

There are multiple sets of universal wheel 411, which are located on the bottom outer wall of storage box 403.

[0025] Based on the above structural features and connection relationships, the electrically controlled cylinder 407 rotates on the outer wall of the rotating rod 406. At the same time, the other end of the electrically controlled cylinder 407 pulls the limiting block 409 through the rotating rod 408, which causes the limiting block 409 to drive the guide plate 404 to move. This causes the guide plate 404 to rotate downward and tilt on the outer wall of the mounting base 401. When the mold part moves out of the stationary template 313, it will slide down the inclined guide plate 404 into the storage box 403 for storage. The inner cavity of the storage box 403 is provided with a buffer pad. When the mold part slides down, it is cushioned by the buffer pad to prevent the mold part from being bumped. The equipment frame 1 has a foot pad 12 at the bottom corner, the stationary template 313 is located directly below the lower pressure block 10, one end of the feeder 11 is connected to the stationary template 313, and the controller 2 is connected to the electrically controlled lower pressure cylinder 7, the feeder 11, the electrically controlled cylinder 303, the electrically controlled hydraulic cylinder 306, the electrically controlled push cylinder 407 and the contact sensor 402 through wires. Under the action of the electrical connection, the device is powered on, and the controller 2 controls the electrically controlled lower pressure cylinder 7, the feeder 11, the electrically controlled cylinder 303, the electrically controlled hydraulic cylinder 306, the electrically controlled push cylinder 407 and the contact sensor 402 to operate.

[0026] Workflow of this invention: When the injection molding equipment for the outer shell of a rat feeding box designed in this scheme and its usage method are in operation, the controller 2 is electrically connected to the electrically controlled pressing cylinder 7, the feeder 11, the electrically controlled cylinder 303, the electrically controlled hydraulic cylinder 306, the electrically controlled pushing cylinder 407, and the contact sensor 402 via wires. This electrically connected connection enables the device to be powered on, thereby causing the controller 2 to control the operation of the electrically controlled pressing cylinder 7, the feeder 11, the electrically controlled cylinder 303, the electrically controlled hydraulic cylinder 306, the electrically controlled pushing cylinder 407, and the contact sensor 402. By turning on the controller 2 and setting the preset parameters, the controller 2 controls the electric cylinder 303 to operate, which causes one end of the electric cylinder 303 to push the clamping side plate 304 to move towards the center, thereby clamping and fixing the static template 313. At the same time, the controller 2 controls one end of the electric pressing cylinder 7 to push the fixed base 9 downward through the pressing rod 8, thereby causing the fixed base 9 to drive the pressing block 10 to fix the static template 313. The controller 2 controls the operation of the electro-hydraulic cylinder 306, which in turn pushes the sealing outer plate 307 to move laterally. This causes the sealing outer plate 307 to move the moving template 308 laterally. When the sealing outer plate 307 moves laterally, it causes the limiting sleeve 309 to move laterally. This causes the limiting sleeve 309 to move laterally on the outer wall of the pull rod 310. At the same time, the limiting sleeve 309 compresses the limiting spring 312 through the baffle 311, which causes the pull rod 310 to push the sliding limiting plate 314 to move laterally. Simultaneously, the sliding limiting plate 314 drives the ejector plate 316 to move laterally through the guide rod 315. This causes the ejector plate 316 to move to the inner side of the static template 313. Then, the moving template 308 and the static template 313 cooperate to facilitate injection molding. At the same time, the controller 2 controls the feeder 11 to perform injection molding on the static template 313. After injection molding is completed, when the controller 2 controls the electro-hydraulic cylinder 306 to reset, one end of the electro-hydraulic cylinder 306 will drive the sealing outer plate 307 to move laterally to reset. In turn, the sealing outer plate 307 will drive the limiting sleeve 309 to move laterally to reset. When the limiting sleeve 309 moves to the appropriate position, the limiting spring 312 will extend. In turn, the limiting sleeve 309 will drive the pull rod 310 to move laterally. The pull rod 310 will drive the sliding limiting plate 314 to move laterally. The sliding limiting plate 314 will drive the ejector plate 316 to move laterally via the guide rod 315. The ejector plate 316 will move outward in the inner cavity of the stationary template 313 so that the ejector plate 316 will eject the mold part from the inner cavity of the stationary template 313. This solves the problem that the current injection molding equipment for the outer shell of the rat breeding box does not have an automatic unloading structure and still requires manual unloading, which is time-consuming and labor-intensive. The controller 2 controls the electro-hydraulic cylinder 306 to reset and move. At the same time, when the ejector plate 316 pushes the mold part out of the stationary template 313, the contact sensor 402 generates an electrical signal when the mold part comes into contact with it. This signal is transmitted to the controller 2 via a wire, which then controls the electro-hydraulic cylinder 407 to rotate on the outer wall of the rotating rod 406. Simultaneously, the other end of the electro-hydraulic cylinder 407 pulls the limit block 409 via the rotating rod 408. This causes the limit block 409 to move the guide plate 404, which then rotates and tilts downward on the outer wall of the mounting base 401. When the mold part moves out of the stationary template 313, it slides down the tilted guide plate 404 into the storage box 403 for storage. This solves the problem that current injection molding equipment for rat breeding box shells often requires manual intervention to remove the workpiece during unloading, which poses a safety risk as the worker's body enters the processing area.

9. A method of using an injection molding equipment for the outer shell of a rat feeding box according to any one of claims 1-8, wherein the specific steps are as follows: Operation Step 1: Turn on the controller (2) and preset parameters, so that the controller (2) controls the electric cylinder (303) to operate, which will cause one end of the electric cylinder (303) to push the clamping side plate (304) to move towards the middle, so that the clamping side plate (304) clamps and fixes the static template (313). At the same time, the controller (2) controls one end of the electric pressing cylinder (7) to push the fixed base (9) downward through the pressing rod (8), so that the fixed base (9) drives the pressing block (10) to fix the static template (313). Operation Step Two: The controller (2) controls the electro-hydraulic cylinder (306) to operate, thereby causing one end of the electro-hydraulic cylinder (306) to push the sealing outer plate (307) to move laterally, thereby causing the sealing outer plate (307) to drive the moving template (308) to move laterally. When the sealing outer plate (307) moves laterally, it will cause the driving limit sleeve (309) of the sealing outer plate (307) to move laterally, thereby causing the limit sleeve (309) to move laterally on the outer wall of the pull rod (310), and at the same time, the limit sleeve ( 309) The limit spring (312) is squeezed and compressed by the baffle (311), which causes the pull rod (310) to push the sliding limit plate (314) to move laterally. At the same time, the sliding limit plate (314) drives the ejector plate (316) to move laterally through the guide rod (315), which will cause the ejector plate (316) to move to the inside of the stationary template (313). Then the moving template (308) and the stationary template (313) cooperate with each other to facilitate injection molding. At the same time, the controller (2) controls the feeder (11) to inject the stationary template (313). Operation Step 3: After injection molding is completed, when the controller (2) controls the electro-hydraulic cylinder (306) to reset, one end of the electro-hydraulic cylinder (306) will drive the sealing outer plate (307) to move laterally to reset, and then the sealing outer plate (307) will drive the limit sleeve (309) to move laterally to reset. When the limit sleeve (309) moves to the appropriate position, the limit spring (312) will extend, and then the limit sleeve (309) will drive the pull rod (310) to move laterally, and the pull rod (310) will drive the sliding limit plate (314) to move laterally, so that the sliding limit plate (314) will drive the ejector plate (316) to move laterally through the guide rod (315), and the ejector plate (316) will move laterally in the inner cavity of the stationary template (313) to move outward, so that the ejector plate (316) will eject the mold part in the inner cavity of the stationary template (313) to unload. Operation Step 4: The controller (2) controls the electro-hydraulic cylinder (306) to reset and move. At the same time, when the ejector plate (316) pushes the mold part out of the stationary template (313), the contact sensor (402) will generate an electrical signal when the mold part comes into contact with the contact sensor (402), which will be transmitted to the controller (2) through the wire. This will cause the controller (2) to control the electro-push cylinder (407) to run, so that the electro-push cylinder (407) rotates on the outer wall of the rotating rod (406). At the same time, the other end of the electro-push cylinder (407) pulls the limit block (409) through the rotating rod (408), which will cause the limit block (409) to drive the guide plate (404) to move, and then cause the guide plate (404) to rotate downward and tilt on the outer wall of the mounting base (401). When the mold part moves out of the stationary template (313), the mold part will slide down along the tilted guide plate (404) into the storage box (403).
