Abstract
Description
Technical Field
[0001] This application relates to the field of injection molding technology, specifically to injection molding pusher devices. Background Technology
[0002] Injection molding is a method of making various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. During injection molding, plastic granules need to be melted, and then a pusher device is used to push the melted plastic into a closed mold cavity. The melted plastic cools to form the finished product.
[0003] However, most existing feeding devices do not have a device for cleaning the discharge pipe. During use, hot melt plastic tends to stick to the inner wall of the discharge pipe during feeding, forming hard residues after cooling. This causes the pipe diameter to shrink, affecting the smoothness of subsequent injection molding. Traditional cleaning methods require stopping the machine to disassemble and manually scrape off the residue, which is inefficient and affects production continuity. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an injection molding pusher device that has advantages such as cleaning the discharge pipe. This solves the problem that most existing pusher devices do not have a device for cleaning the discharge pipe. During use, hot melt plastic tends to stick to the inner wall of the discharge pipe during the pushing process, forming hard residues after cooling, which reduces the pipe diameter and affects the smoothness of subsequent injection molding. Traditional cleaning methods require stopping the machine for disassembly and manual scraping, which is inefficient and affects the continuity of production.
[0005] To achieve the above objectives, this application provides the following technical solution: an injection molding pusher device, including a base plate moving platform. A groove is provided on one side of the upper end of the base plate. Two slide rods arranged in a mirror image are fixedly connected inside the groove. A moving plate is slidably arranged outside the two slide rods. Two dovetail grooves arranged in a mirror image are provided on one side of the upper end of the moving platform. Two dovetail tenons arranged in a mirror image are fixedly connected to the bottom end of the moving platform. The two dovetail tenons are slidably arranged inside the dovetail grooves. A sleeve is fixedly connected to the upper end of the moving platform. A spiral drill is rotatably arranged inside the sleeve. A first motor is fixedly connected to one side of the sleeve. A discharge pipe is fixedly connected to the bottom end of the outer wall of the sleeve. A collection box is fixedly connected to one side of the moving platform. The bottom end of the discharge pipe is fixedly connected to the collection box. A collection hopper is slidably connected inside the collection box.
[0006] The above solution utilizes the sliding grooves and rods on the base plate to achieve stable sliding of the moving plate. The dovetail grooves on the moving plate engage with the dovetail tenons of the moving table, enabling stable sliding of the moving table. The sleeve and auger design inside the moving table, driven by the first motor, can clean the residual plastic in the discharge pipe. The discharge pipe guides the cleaned waste material into the collection hopper in the collection box for automatic collection. The overall structure is compact and easy to operate, enabling cleaning to be completed without disassembling the equipment, improving production efficiency, reducing manual intervention, and ensuring the continuity and stability of the injection molding process.
[0007] Furthermore, a mounting base is fixedly connected to one side of the upper end of the movable plate, and two first electric push rods arranged in a mirror image are fixedly connected inside the mounting base. The telescopic ends of the two first electric push rods are fixedly connected to one side of the movable platform.
[0008] With the above scheme, the two first electric push rods serve as the driving device for the moving platform, and the moving platform is moved by the extension and retraction of the two first electric push rods.
[0009] Furthermore, two second electric push rods arranged in a mirror image are fixedly connected to one side of the inside of the chute, and the telescopic ends of the two second electric push rods are fixedly connected to one side of the moving plate.
[0010] With the above scheme, the two second electric push rods serve as the driving device for the moving plate, and drive the moving plate to slide on the outer wall of the slide rod.
[0011] Furthermore, a pipe is fixedly connected to the upper end of the base plate, and an auger is rotatably connected inside the pipe. A second motor is fixedly connected to the side of the upper end of the base plate away from the slide groove, and the output end of the second motor is fixedly connected to the auger through a coupling.
[0012] The above scheme achieves efficient conveying of plastic raw materials by setting a tube and auger on the base plate and cooperating with a second motor drive. The rotational movement of the auger in the tube ensures that the plastic granules are pushed forward evenly and stably. The second motor directly drives the auger through a coupling, which has high transmission efficiency and smooth operation, making the entire feeding process smoother.
[0013] Furthermore, a feed hopper is fixedly installed on one side of the upper end of the tube, and a discharge pipe is fixedly installed at one end of the tube.
[0014] The above solution allows for the convenient and quick addition of plastic granules to the feeding device by setting a feeding hopper at the upper end of the pipe, while the discharge pipe at one end of the pipe connects to the subsequent process.
[0015] Furthermore, four legs arranged in a rectangular array are fixedly connected to the bottom end of the base plate.
[0016] The above scheme provides a stable and reliable support foundation for the entire device with four legs arranged in a rectangular array. The symmetrical arrangement of the four legs ensures that the weight of the device is evenly distributed, preventing swaying and tilting during operation.
[0017] Furthermore, the output end of the first motor is fixedly connected to the auger drill through the sleeve.
[0018] With the above scheme, the first motor serves as the power source for the auger, driving its rotation.
[0019] Furthermore, the auger is rotatably disposed inside the discharge pipe, and the discharge pipe is slidably disposed inside the sleeve.
[0020] The above solution involves placing the auger inside the discharge pipe and enabling it to rotate, while the discharge pipe is slidably positioned inside the sleeve. The auger can effectively crush and transport residual plastic when rotating, and the sliding arrangement of the discharge pipe allows it to move axially in conjunction with the auger, forming a combined rotational and pushing-pull cleaning action to ensure the thorough removal of residues from the pipe wall.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This injection molding ejector device achieves stable sliding of the moving plate through a sliding groove and sliding rod on the base plate. The dovetail groove on the moving plate cooperates with the dovetail tenon of the moving table, enabling the moving table to slide stably. The sleeve and spiral drill design inside the moving table, driven by a first motor, can clean the residual plastic in the discharge pipe. The discharge pipe guides the cleaned waste material into the collection hopper in the collection box for automatic collection. The overall structure is compact and easy to operate, and can complete the cleaning without disassembling the equipment, improving production efficiency, reducing manual intervention, and ensuring the continuity and stability of the injection molding process.

Slide the dovetail groove 5 on the 4 and adjust the position of the moving table 6 so that the sleeve 8 and the spiral drill 9 are aligned with the discharge pipe 21. Start the first motor 10 to drive the spiral drill 9 to rotate inside the discharge pipe 21, forming a rotating cutting and axial pushing cleaning action inside the discharge pipe 21, breaking and discharging the pipe wall residue. During the cleaning process, the cleaned waste is introduced into the collection hopper 13 inside the collection box 12 through the discharge pipe 11. When the waste in the collection hopper 13 reaches a certain amount, the operator can pull it out of the collection box 12 and clean it.
