Description

Technical Field

[0001] This utility model relates to the technical field of monitor bracket processing equipment, specifically to a sprue cutting and edge pressing device. Background Technology

[0002] In the manufacturing of monitor stands, injection molding is the primary processing method for the base and top cover. Due to the characteristics of the injection molding process, after molding, these injection-molded parts often have excess material residue at the sprue. Simultaneously, the outer edges are prone to burrs and flash due to factors such as mold closing precision and material flowability. This not only affects the product's appearance quality but may also cause installation difficulties during subsequent assembly, and even pose a risk of scratches to operators. Currently, the cleaning and edge shaping of the sprue and top cover of the monitor stand injection-molded base typically involves manual removal of the sprue using tools or specialized sprue-cutting equipment, followed by manual finishing with hand-held grinding tools or a separate edge-pressing device. These two processes must be completed on different equipment, requiring manual transfer of the workpiece between machines. This not only increases the labor intensity of operators, extends the production cycle, and reduces overall processing efficiency, but also makes it difficult to guarantee consistency in manual operation. The depth and position of the sprue cut, as well as the pressure applied to the edge, all rely on the operator's experience, making operational errors prone to occur. This results in poor product quality stability and a high defect rate.

[0003] Based on the above, this utility model proposes a water-cutting and edge-pressing device, which can effectively solve the above problems. Utility Model Content

[0019] The U-shaped groove 51 on the product fixture 5 and the circular hole 31 and positioning sleeve 32 on the fixture mounting plate 3 work together to enable the gate cutting mechanism 7 to accurately position the gate of the injection molded product during processing.

[0020] Furthermore, in another embodiment, the pressing mechanism 6 includes a first Y-axis moving component 61 fixedly connected to the top of the support frame 2, the first Y-axis moving component 61 being slidably connected to a first X-axis moving component 62, the first X-axis moving component 62 being slidably connected to a first Z-axis moving component 63, and the first Z-axis moving component 63 being connected to a pressing post 64.

[0021] By setting the edge pressing mechanism 6, the first Y-axis moving component 61, the first X-axis moving component 62 and the first Z-axis moving component 63 can drive the edge pressing column 64 to move in three-dimensional space. The position of the edge pressing column 64 can be adjusted according to the different peripheral positions of the product to press the outer edge of the injection molded product for shaping and deburring.

[0022] Furthermore, in another embodiment, the water-cutting mechanism 7 includes a second Y-axis moving component 71 fixedly connected to the top of the frame 1, a second X-axis moving component 72 slidably connected to the second Y-axis moving component 71, a second Z-axis moving component 73 slidably connected to the second X-axis moving component 72, a drive motor 75 connected to the second Z-axis moving component 73 via a fixed base 74, and a spiral milling cutter 76 fixedly connected to the output end of the drive motor 75.

[0023] By setting the sprue cutting mechanism 7, the spiral milling cutter 76 can move in three-dimensional space through the second Y-axis moving component 71, the second X-axis moving component 72, and the second Z-axis moving component 73, which can accurately align with the sprue position of the injection molded product; the drive motor 75 on the second Z-axis moving component 73 drives the spiral milling cutter 76 to rotate at high speed, which can efficiently and accurately clean the burrs at the sprue.

[0024] Furthermore, in another embodiment, a protective cover 8 is fixedly connected to the top outer periphery of the frame 1, and a feeding mechanism 9 is fixedly connected to the top of the protective cover 8.

[0025] By installing a protective cover 8 on the outer periphery of the top of the frame 1 (the isolation plate is omitted in the attached figure, only the frame is shown), the processing area of ​​the equipment can be isolated from the outside, preventing the flying debris generated during processing from causing injury to the operator.

[0026] Furthermore, in another embodiment, the feeding mechanism 9 includes a third Y-axis moving component 91 fixedly connected to the top of the protective cover 8. The third Y-axis moving component 91 is fixedly connected to a cylinder 92. The telescopic end of the cylinder 92 is fixedly connected to a lifting plate 93. Multiple connecting posts 94 are fixedly connected to both sides of the lifting plate 93. A suction nozzle 95 is fixedly connected to the bottom of the connecting post 94.

[0027] By setting up the unloading mechanism 9, the third Y-axis moving component 91 of the unloading mechanism 9 can drive components such as the cylinder 92 and the lifting plate 93 to move in the Y direction. The cylinder 92 can drive the lifting plate 93 to move up and down, thereby driving the suction nozzle 95 at the bottom of the connecting column 94 to move. The suction nozzle 95 can adsorb the injection molded product through negative pressure. Through the coordinated action of each component, the precise and stable automatic unloading of the injection molded product is achieved.

[0028] The working principle of one embodiment of this utility model is as follows: First, the operator places the injection molded part on the product fixture 5 on top of the fixture mounting plate 3. Then, the edge-pressing process begins. The first Y-axis moving component 61, the first X-axis moving component 62, and the first Z-axis moving component 63 drive the edge-pressing column 64 to move in three-dimensional space. The position of the edge-pressing column 64 is adjusted according to the different positions of the injection molded part's outer perimeter, performing edge-pressing operations to achieve shaping and deburring effects. Simultaneously, the sprue cutting mechanism 7 works synchronously. Its second Y-axis moving component 71, the second X-axis moving component 72, and the second Z-axis moving component 73 work in tandem, driving the spiral milling cutter 76 to move in three-dimensional space, precisely aligning it with the sprue position of the injection molded part. Subsequently, the drive motor 75 starts, driving the spiral milling cutter 76 to rotate at high speed, cleaning the sprue and efficiently removing burrs and other excess parts.

[0029] After the sprue cutting and edge pressing processes are completed, the unloading mechanism 9 begins operation. The third Y-axis moving component 91 drives the cylinder 92, lifting plate 93, and other components to move in the Y direction. The cylinder 92 drives the lifting plate 93 to move downward, so that the suction nozzle 95 at the bottom of the connecting column 94 contacts the finished injection molded part. The suction nozzle 95 uses negative pressure to hold the product in place. Then, the cylinder 92 drives the lifting plate 93 to rise, and the third Y-axis moving component 91 moves the product to the designated unloading position. The suction nozzle 95 releases the negative pressure, completing the automatic unloading of the product.
