Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology, and in particular to an automatic sprue cutting device. Background Technology

[0002] Currently, when producing plastic parts such as fan covers and water purifier covers in the workshop, the sprue gates need to be cut after the products are removed from the injection mold. Moreover, these products are generally produced in a row, requiring the sprue gates of the entire row of products to be cut off. Currently, the sprue gates are usually cut manually, but this method is labor-intensive, inefficient, and prone to errors, which can damage the products and ultimately render them unusable.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic sprue cutting device that is simple in structure, low in labor intensity, high in shearing efficiency, high in product quality, and highly practical, so as to overcome the shortcomings of the existing technology.

[0005] An automatic sprue cutting device designed for this purpose includes a base, characterized in that it further includes a shearing device and a feeding device. The shearing device is movably mounted on the base, and the feeding device is fixedly mounted on the base. The shearing device includes a drive assembly and several pressing and cutting assemblies. The drive assembly drives and connects to the pressing and cutting assemblies. The pressing and cutting assemblies include pressing components and cutters, with the cutters mounted on the pressing components. When cutting a workpiece, the shearing device moves toward the feeding device so that the pressing and cutting assemblies move above the feeding device. The drive assembly drives the pressing and cutting assemblies to move downward. When the pressing components move downward to the corresponding position, they press the workpiece on the feeding device. The cutters move downward relative to the pressing components and cut off the sprue on the workpiece.

[0006] The pressing component includes a telescopic pressing plate and a telescopic body. The telescopic pressing plate is mounted on the telescopic body, which extends and retracts relative to each other. The cutter is mounted on the telescopic body. When the pressing component moves downward to the corresponding position, the telescopic pressing plate presses the workpiece on the unloading device. The telescopic body drives the cutter to move downward relative to the telescopic pressing plate so that the cutter cuts the sprue on the workpiece. When the drive component drives the pressing and cutting component to move upward, the telescopic pressing plate moves downward relative to the telescopic body and resets under the action of gravity.

[0007] The telescopic pressure plate is equipped with a movable rod, and the telescopic body is equipped with a movable hole. The movable rod is mounted on the movable hole and moves up and down.

[0008] The drive assembly includes a first driver and a movable pressure plate. The first driver drives the movable pressure plate, and the telescopic body is fixed on the movable pressure plate. The first driver drives the material pressing and cutting assembly to move up and down through the movable pressure plate.

[0009] The shearing device also includes a movable frame, a first driver fixed on the movable frame, and a second driver on the base. The second driver drives the movable frame to move on the base.

[0010] The movable frame has a cavity, and the pressing and cutting assembly is located in the cavity and at the top of the cavity. When the shearing device moves toward the feeding device, the feeding device enters the cavity and is located at the bottom of the cavity.

[0011] The feeding device includes a positioning component, which includes a base and several positioning parts set on the base. When the workpiece is placed in the feeding device, the workpiece is sleeved on the positioning parts and the bottom of the workpiece is supported on the base. The base is provided with a waste trough for receiving the sprue.

[0012] The feeding device also includes several third drivers, each corresponding to a positioning component. The third drivers drive the connecting base. Before the workpiece's sprue is cut, the third drivers drive the positioning components to move downwards. After the workpiece's sprue is cut, the third drivers drive the positioning components to move upwards.

[0013] The base is equipped with slide rails, and the bottom of the movable frame is equipped with sliding guide bars. The movable frame slides on the slide rails via the sliding guide bars.

[0014] The movable pressure plate is equipped with guide columns, and the movable frame is equipped with guide sleeves. The guide columns pass through the guide sleeves. When the first driver drives the material pressing and cutting assembly to move up and down through the movable pressure plate, the guide columns move up and down on the guide sleeves.

[0015] This invention provides an automatic sprue cutting device. By setting up a cutting device and a feeding device, the cutting device includes a drive assembly and several pressing and cutting assemblies. The feeding device includes a positioning assembly for positioning a row of workpieces. During workpiece cutting, the pressing components move downwards to press the workpieces on the feeding device, and the cutter moves downwards relative to the pressing components to cut off the sprue on the workpiece, achieving automatic cutting and separation of the glue inlet. The entire cutting process is basically completed automatically by the equipment. The operator only needs to place the workpiece on the feeding device and then start the switch. This greatly reduces the labor intensity of workers and improves the sprue cutting efficiency. Moreover, the workpiece is pressed down by the pressing components before cutting, preventing the workpiece from loosening during cutting and potentially damaging it, thus improving product quality and yield.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See Figures 1-4 This automatic sprue cutting device includes a base 1, a shearing device 2, and a feeding device 3. The shearing device 2 is movably mounted on the base 1, and the feeding device 3 is fixedly mounted on the base 1. The shearing device 2 includes a drive assembly and several pressing and cutting assemblies. The drive assembly drives and connects to the pressing and cutting assemblies. The pressing and cutting assemblies include pressing components 4 and cutters 5. The cutters 5 are mounted on the pressing components 4. When cutting a workpiece, the shearing device 2 moves towards the feeding device 3 so that the pressing and cutting assemblies move above the feeding device 3. The drive assembly drives the pressing and cutting assemblies to move downward. When the pressing components 4 move downward to the corresponding position, they press the workpiece on the feeding device 3. Then, the cutters 5 move downward relative to the pressing components 4 and cut off the glue inlet on the workpiece. The workpiece can be a fan cover or a water purifier cover, etc.

[0022] The pressing component 4 includes a telescopic pressing plate 6 and a telescopic body 7. The telescopic pressing plate 6 is mounted on the telescopic body 7 in a vertically extending manner. The cutter 5 is mounted on the telescopic body 7 by screws. When the pressing component 4 moves downward to the corresponding position, the telescopic pressing plate 6 presses the workpiece on the unloading device 3. At this time, the telescopic pressing plate 6 can no longer move downward. The drive component drives the telescopic body 7 to continue moving downward, so that the telescopic body 7 drives the cutter 5 to move downward relative to the telescopic pressing plate 6, thereby causing the cutter 5 to cut off the glue inlet on the workpiece. When the drive component drives the pressing and cutting component to move upward, the telescopic pressing plate 6 moves downward relative to the telescopic body 7 and resets under the action of gravity.

[0023] The telescopic pressure plate 6 is provided with a movable rod 8, and the telescopic body 7 is provided with a movable hole 9. The movable rod 8 is movably mounted on the movable hole 9. The movable rod 8 is provided with a limiting boss, and the hole wall of the movable hole 9 is provided with a limiting step. When the telescopic pressure plate 6 moves downward relative to the telescopic body 7 to reset under the action of gravity, it is limited downward by the limiting boss to the limiting step, so as to prevent the telescopic pressure plate 6 from falling out of the telescopic body 7.

[0024] The drive assembly includes a first driver 10 and a movable pressure plate 11. The first driver 10 drives the movable pressure plate 11. The telescopic body 7 is fixed on the movable pressure plate 11. The first driver 10 drives the material pressing and cutting assembly to move up and down through the movable pressure plate 11. The first driver 10 is a cylinder.

[0025] The shearing device 2 also includes a movable frame 12. The first driver 10 is fixed on the movable frame 12. A second driver (not shown in the figure) is provided on the base 1. The second driver drives the movable frame 12 to move on the base 1. The second driver is a cylinder. When the cutter 5 cuts the glue inlet on the workpiece, the drive assembly drives the pressing and cutting assembly to move upward. The second driver drives the shearing device 2 to move in the opposite direction to the feeding device 3.

[0026] The movable frame 12 is provided with a cavity 13. The pressing and cutting assembly and the movable pressure plate 11 are arranged in the cavity 13 and located at the upper part of the cavity 13. When the shearing device 2 moves in the direction of the feeding device 3, the feeding device 3 enters the cavity 13 and is located at the lower part of the cavity 13. The cavity 13 is used to avoid the feeding device 3 when the shearing device 2 moves.

[0027] The feeding device 3 includes a positioning component, which includes a base 14 and several positioning elements 15 disposed on the base 14. The positioning elements 15 correspond one-to-one with the pressing and cutting components. When the workpiece is placed on the feeding device 3, the workpiece is fitted onto the positioning element 15, and the bottom of the workpiece is supported on the base 14, thereby positioning the workpiece. Specifically, a positioning hole is provided in the center of the workpiece, and the positioning element 15 is a positioning boss. The workpiece is fitted onto the positioning boss through the positioning hole. The workpiece is formed by a die-cutting process, so the entire row of workpieces, along with the glue inlet, is placed on the base 14, and each workpiece is fitted onto the corresponding positioning element 15. The base 14 is provided with a waste trough 21 for receiving the glue inlet. When the cutter 5 cuts off the glue inlet on the workpiece, the glue inlet falls into the waste trough 21, and then the operator can remove the glue inlet from the waste trough 21.

[0028] The feeding device 3 also includes several third drivers 16, each corresponding to a positioning component 15. The third drivers 16 are fixed on the base 1 and drive the connecting base 14. Before the workpiece is cut, the third drivers 16 drive the positioning component to move downward, and then place the workpiece on the positioning component. Subsequently, the cutting device 2 is started to cut off the glue inlet on the workpiece. After the workpiece is cut, the third drivers 16 drive the positioning component to move upward, thereby lifting or popping the workpiece upward. The third drivers 16 are cylinders.

[0029] The positioning component is equipped with cooling water channels, which allows the product on the positioning component to be cooled and solidified more quickly, reducing the in-mold molding cycle and ensuring product quality.

[0030] A start button 22 is provided at one end of the base 1. When the start button 22 is pressed, the first driver 10, the second driver and the third driver 16 are activated to perform the sprue cutting process of the workpiece.

[0031] The base 1 is provided with a slide rail 17, and the bottom of the movable frame 12 is provided with a sliding guide bar 18. The movable frame 12 slides on the slide rail 17 through the sliding guide bar 18 to guide the movement of the movable frame 12.

[0032] The movable pressure plate 11 is provided with a guide post 19, and the movable frame 12 is provided with a guide sleeve 20. The guide post 19 passes through the guide sleeve 20. When the first driver 10 drives the pressing and cutting assembly to move up and down through the movable pressure plate 11, the guide post 19 moves up and down on the guide sleeve 20 to guide the movement of the movable pressure plate 11.
