Description

Technical Field

[0001] This utility model relates to the field of injection molding material feeding technology, specifically an injection molding material feeding device for card bag injection molding. Background Technology

[0002] Injection feeding for card holder injection molding refers to the process of conveying pre-prepared raw materials to the injection molding machine hopper through an automated feeding system in the card holder injection molding process. This step is a pre-process of injection molding production, ensuring a quantitative and uniform continuous supply of raw materials. After being melted at high temperature, the raw materials are injected into the precision mold by the injection molding machine under high pressure, and finally cooled and shaped into card holder products that meet the design requirements. However, due to the high height of the injection molding machine hopper, manual loading requires climbing to work, which poses a safety hazard and also leads to time-consuming and labor-intensive loading. At the same time, when loading the injection molding machine, the granular, highly hygroscopic material is prone to clogging at the bends in the pipes, which affects the injection molding efficiency of the machine.

[0003] Therefore, a new injection molding feeding device for cardboard injection molding is needed to improve the above problems. Utility Model Content

[0004] To address the issue that the high height of the injection molding machine hopper during card bag injection molding requires manual loading, posing safety hazards and making loading time-consuming and labor-intensive, this invention provides an injection molding loading device for card bag injection molding to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An injection molding feeding device for card holder injection molding includes a mounting base, an injection molding machine is mounted on the base surface of the mounting base, a support column is mounted on one side of the injection molding machine and on the outer wall of the mounting base, and a controller is mounted on one end of the support column; The injection molding machine has a material storage component installed at its feed inlet, and the mounting base has a mounting groove on its outer wall. The mounting groove has a feeding component installed on its inner wall.

[0006] As a preferred embodiment of this utility model, the material storage assembly includes a material storage tank, which is embedded in the feed inlet of an injection molding machine. A guide shell is installed on the outer wall of the material storage tank, and a guide sleeve is embedded opposite to the guide shell. A cutting blade is slidably connected to the outer wall of the guide sleeve, and the cutting blade is located in the inner cavity of the guide shell. One end of the guide sleeve extends to the outer wall of the guide shell, and the connection between the guide sleeve and the guide shell is a continuous structure.

[0007] As a preferred embodiment of this utility model, an electrically controlled push-pull cylinder is installed on the outer wall of the material guide housing, wherein one end of the electrically controlled push-pull cylinder extends into the inner cavity of the guide sleeve and is connected to a cutting blade, an mounting plate is installed on the inner wall of the material guide housing, and an adjustable heater is installed on the outer wall of the mounting plate, wherein one end of the adjustable heater passes through the mounting plate and extends into the inner wall of the material guide housing.

[0008] As a preferred embodiment of this utility model, the feeding assembly includes a mounting bracket, which is installed on the inner wall of the mounting groove. The top of the mounting bracket is flush with the port of the guide housing. A rack is installed on the opposite outer wall of the mounting bracket. A fixed frame is slidably connected to one side of the rack and located on the inner wall of the mounting bracket. A drive motor is installed on the outer wall of one side of the fixed frame. A gearbox is installed on the drive shaft of the drive motor. The gearbox is installed on the outer wall of the fixed frame.

[0009] As a preferred embodiment of this utility model, the output shaft opposite to the gearbox is equipped with a transmission gear, which is meshed with the outer wall of the rack. A fixing block is installed on the outer wall of the fixing frame, wherein the cross-section of the fixing block is L-shaped. The fixing block is rotatably connected to a mounting base plate via a rotating shaft. Electrically controlled cylinders are symmetrically installed on the bottom outer wall of the mounting base plate.

[0010] As a preferred embodiment of this utility model, a pull rod is installed at one end of the electronically controlled cylinder, wherein one end of the pull rod passes through the mounting base plate and extends to the outer wall of the mounting base plate to install a lower pressure plate, and a positioning block is installed on the inner wall of the fixing block.

[0011] As a preferred embodiment of this utility model, an electrically controlled telescopic cylinder is rotatably connected to the inner wall of the positioning block, and a limit block is rotatably connected to one end of the electrically controlled telescopic cylinder. The limit block is installed on the bottom outer wall of the mounting base plate, and a contact sensor is installed on the top outer wall of the mounting bracket.

[0012] As a preferred embodiment of this utility model, the controller is connected to an injection molding machine, an electrically controlled push-pull cylinder, an adjustable heater, a drive motor, an electrically controlled cylinder, an electrically controlled telescopic cylinder, and a contact sensor via wires, and the connection method is electrical connection.

[0013] Compared with the prior art, this utility model can realize automatic feeding of injection molding machines by setting a feeding component in the injection molding feeding device for card bag injection molding. The controller drives the electric cylinder to move the lower pressure block to fix the material bag. The controller sequentially starts the drive motor, which drives the fixed frame to rise vertically along the rack through the gearbox and transmission gear. After reaching the position, the electric telescopic cylinder pushes the mounting base plate to rotate around the rotating shaft, so that the material bag hangs upside down on the outer wall of the guide sleeve and triggers the contact sensor. Then the controller activates the electric push-pull cylinder to drive the cutting blade to move laterally, completing the cutting of the material bag. The cut material then falls into the inner cavity of the guide shell, thus solving the problem that the injection molding machine hopper is too high, and manual feeding requires climbing to work, which poses safety hazards and is time-consuming and labor-intensive.

[0014] This invention enables the preheating of raw materials by incorporating a material storage component in the injection molding feeding device for card-type injection molding. A contact sensor generates an electrical signal, which is transmitted to the controller via wires. When the set parameters are reached, the controller activates an adjustable heater. Since one end of the adjustable heater is connected to the inner wall of the guide housing, it preheats the raw materials within the guide housing cavity to prevent them from sticking and affecting subsequent injection molding processes. Simultaneously, the mounting plate within the guide housing obstructs the raw materials, increasing their heating time. This solves the problem of granular, highly hygroscopic materials easily clogging at pipe bends during injection molding, thus affecting the injection molding efficiency. Attached Figure Description

[0020] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The feeding assembly 7 includes a mounting bracket 701, which is installed on the inner wall of the mounting groove 6. The top of the mounting bracket 701 is flush with the port of the guide housing 502. A rack 702 is mounted on the opposite outer wall of the mounting bracket 701. A fixed frame 703 is slidably connected to one side of the rack 702 and located on the inner wall of the mounting bracket 701. A drive motor 704 is mounted on the outer wall of one side of the fixed frame 703. A gearbox 705 is mounted on the drive shaft of the drive motor 704. The gearbox 705 is mounted on the outer wall of the fixed frame 703. A transmission gear 706 is mounted on the opposite output shaft of the gearbox 705. The transmission gear 706 is meshed with the outer wall of the rack 702. A fixed frame 706 is mounted on the outer wall of the fixed frame 703. Block 707, wherein the fixed block 707 has an L-shaped cross-section, the fixed block 707 is rotatably connected to the mounting base plate 709 via the rotating shaft 708, the bottom outer wall of the mounting base plate 709 is symmetrically equipped with an electric control cylinder 710, one end of the electric control cylinder 710 is equipped with a pull rod 711, one end of the pull rod 711 passes through the mounting base plate 709 and extends to the outer wall of the mounting base plate 709 to be equipped with a lower pressure plate 712, the inner wall of the fixed block 707 is equipped with a positioning block 713, the inner wall of the positioning block 713 is rotatably connected with an electric control telescopic cylinder 714, one end of the electric control telescopic cylinder 714 is rotatably connected with a limit block 715, the limit block 715 is installed on the bottom outer wall of the mounting base plate 709, and the top outer wall of the mounting bracket 701 is equipped with a contact sensor 716; Based on the above structural features and connection relationships, the raw material package is shaken before use so that the raw materials accumulate at the bottom, resulting in only the hollow bag body at the top of the raw material package. Then, the hollow bag body is inserted directly below the lower pressure plate 712. Subsequently, one end of the electric cylinder 710 drives the pull rod 711 to move downward, which in turn causes the pull rod 711 to drive the lower pressure plate 712 to move downward, so that the lower pressure plate 712 clamps and fixes one side of the raw material package. The controller 4 is electrically connected to the injection molding machine 2, the electrically controlled push-pull cylinder 505, the adjustable heater 507, the drive motor 704, the electrically controlled cylinder 710, the electrically controlled telescopic cylinder 714, and the contact sensor 716 via wires. This connection enables the device to be powered on, thereby allowing the controller 4 to control the operation of the injection molding machine 2, the electrically controlled push-pull cylinder 505, the adjustable heater 507, the drive motor 704, the electrically controlled cylinder 710, the electrically controlled telescopic cylinder 714, and the contact sensor 716.

[0021] When the injection molding feeding device for card bag injection molding is working, the controller 4 is connected to the injection molding machine 2, the electric push-pull cylinder 505, the adjustable heater 507, the drive motor 704, the electric cylinder 710, the electric telescopic cylinder 714, and the contact sensor 716 through wires. The device is powered on, and the controller 4 controls the injection molding machine 2, the electric push-pull cylinder 505, the adjustable heater 507, the drive motor 704, the electric cylinder 710, the electric telescopic cylinder 714, and the contact sensor 716 to operate. The raw material package is placed on the base surface of the mounting plate 709. Then, the switch of the controller 4 is turned on, so that the controller 4 controls the electric cylinder 710 to operate. This causes one end of the electric cylinder 710 to drive the pull rod 711 to move downward, which in turn causes the pull rod 711 to drive the lower pressure plate 712 to move downward. This causes the lower pressure plate 712 to clamp and fix one side of the raw material package. Then, the switch of the controller 4 is turned on, so that the controller 4 controls the drive motor 704 to operate. This causes the drive shaft of the drive motor 704 to drive the gearbox 705, which in turn causes the power shaft of the gearbox 705 to drive the transmission gear 706 to operate. The transmission gear 706 is meshed with the outer wall of the rack 702 and moves longitudinally. When the transmission gear 706 moves longitudinally on the outer wall of the rack 702, the fixed frame 703 moves upward on the inner wall of the mounting bracket 701 and is lifted. When the fixed frame 703 reaches the top of the mounting bracket 701, the operator turns on the controller 4, causing the controller 4 to control the electrically controlled telescopic cylinder 714. The electrically controlled telescopic cylinder 714 applies a thrust to the mounting base plate 709 via the limit block 715, causing the mounting base plate 709 to rotate on the outer wall of the rotating shaft 708. Since one end of the raw material bag is fixed, when the mounting base plate 709 drives the raw material bag to flip, the raw material bag will flip. Hanging on the outer wall of the guide sleeve 503, the raw material package comes into contact with the contact sensor 716, which generates an electrical signal that is transmitted to the controller 4 via a wire. When the set parameters are reached, the controller 4 controls the electric push-pull cylinder 505 to operate, so that one end of the electric push-pull cylinder 505 pushes the cutting blade 504 to move laterally, thereby cutting the raw material package and causing the raw material to fall into the inner cavity of the guide housing 502. This solves the problem that the injection molding machine hopper is too high, and manual loading requires climbing to work, which poses a safety hazard and is time-consuming and laborious. By generating an electrical signal through the contact sensor 716 and transmitting it to the controller 4 via a wire, the controller 4 will control the adjustable heater 507 to operate when the set parameters are reached. Since one end of the adjustable heater 507 is connected to the inner wall of the guide housing 502, the adjustable heater 507 will preheat the raw material in the inner cavity of the guide housing 502 to prevent the raw material from sticking and affecting subsequent injection molding. At the same time, the mounting plate 506 in the inner cavity of the guide housing 502 will block the raw material to increase the heating time of the raw material. This is practical and solves the problem that when the injection molding machine is feeding material, the granular and highly hygroscopic material is easy to clog at the bend of the pipe, which will affect the injection molding efficiency of the injection molding machine.
