Description

Technical Field

[0001] This utility model relates to the field of precision injection molded parts, and specifically to a cutting device for precision injection molded parts. Background Technology

[0002] Precision injection molded parts are plastic products manufactured using high-precision injection molding technology. They must simultaneously meet the triple standards of extreme dimensional accuracy, excellent surface quality, and complex structural design. Precision injection molded part cutting equipment is a high-precision processing device specifically designed for injection-molded plastic parts. Its core technology lies in achieving high-precision cutting through automated control and precision mechanical structure, while ensuring cut surface quality and production efficiency. It is widely used in medical, electronics, optics, automotive and other fields.

[0003] Existing precision injection molded parts cutting equipment suffers from several drawbacks during use. Due to the high cutting precision of precision injection molded parts, physical cutting with only blades affects the processing quality. The edges of the precision injection molded parts after cutting need to be ground again. Furthermore, cutting precision injection molded parts with a single blade reduces the overall cutting precision when dealing with precision injection molded parts of different materials. As a result, the overall applicability of the equipment decreases over time, and the cutting efficiency of precision injection molded parts is also reduced.

[0004] Therefore, it is necessary to invent a precision injection molding part cutting device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a precision injection molded part cutting device. Through a cutting table, cutting blade, electromagnetic induction coil, longitudinal electric slide rail, gantry frame, transverse electric slide rail, laser cutting head, and laser, the device enables two different cutting modes. Different modes can be switched for different precision injection molded parts. The hot blade mode is suitable for large-area cutting of thermoplastic materials, reducing cutting costs, while the laser mode can perform fine processing on high-temperature sensitive materials, improving cutting accuracy. This not only improves the overall cutting accuracy of the precision injection molded part cutting device but also expands its application range. This addresses the problem in existing precision injection molded part cutting devices where, due to the high cutting precision of precision injection molded parts, physical cutting with only a blade affects processing quality, requiring secondary grinding of the cut edges. Furthermore, using a single blade for cutting precision injection molded parts of different materials reduces overall cutting accuracy, leading to reduced overall applicability and cutting efficiency over long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for precision injection molded parts, including a cutting table for placing the main body of the precision injection molded part;

[0007] A processing fence is threadedly connected to the top of the cutting table to limit the cutting range. Cutting openings are provided on both sides of the top of the cutting table. A cutting machine body is fixedly installed on the outer sides of the processing fence, and a drive controller is fixedly installed on the outside of the cutting machine body.

[0008] A servo motor is fixedly installed inside the cutting machine body. A rotating rod is fixedly connected to the output end. A cutting blade is fixedly installed at the other end of the rotating rod. An electromagnetic induction coil is fixedly installed on the outside of the cutting blade. Thermocouple sensors are fixedly installed on the upper and lower sides of the outside of the cutting blade.

[0009] A longitudinal electric slide rail is fixedly installed on both sides of the outer side of the processing enclosure for external sliding connection of a longitudinal electric slide sleeve. A gantry frame is fixedly installed on the outside of the longitudinal electric slide sleeve. A transverse electric slide rail is fixedly installed above the gantry frame. A transverse electric slide sleeve is slidably connected to the outside of the transverse electric slide rail. A laser cutting head is fixedly installed at the bottom of the transverse electric slide sleeve. A laser is fixedly installed on the outside of the gantry frame.

[0010] Preferably, the processing enclosure is threadedly connected to the cutting table, and the cutting blades are symmetrically arranged about the central axis of the cutting table.

[0011] Preferably, the lower end of the cutting blade is rotatably connected within the cutting opening, and the rotating rod is integrally formed with the cutting blade.

[0012] Preferably, a push electric slide rail is fixedly provided above the cutting table, and a push electric slide sleeve is slidably connected to the outside of the push electric slide rail.

[0013] Preferably, a cutting plate is fixedly installed above the electric sliding sleeve, and a workpiece clamp is threadedly connected to the top of the cutting plate.

[0014] Preferably, the gantry frame is slidably connected to the cutting table, and the laser cutting head is perpendicularly distributed to the cutting table.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model includes a cutting table, a cutting blade, an electromagnetic induction coil, a longitudinal electric slide rail, a gantry frame, a transverse electric slide rail, a laser cutting head, and a laser. When using this precision injection molded part cutting device, due to the precision requirements of cutting precision injection molded parts, different cutting methods can be selected according to different precision injection molded parts. The electromagnetic induction coil is energized to heat the cutting blade, causing the blade edge to form a thermal cut when cutting the precision injection molded part due to heat transfer, thereby making the cutting position smooth and reducing residue. At the same time, it is necessary to ensure the surface of the precision injection molded part... For fine cutting, the longitudinal and transverse electric slide rails can drive the laser cutting head to emit laser light, using the laser to perform fine cutting of precision injection molded parts. This gives the precision injection molded parts cutting device two different cutting methods, allowing for different mode switching for different precision injection molded parts. The hot knife mode is suitable for large-area cutting of thermoplastic materials, reducing cutting costs, while the laser mode can be used for fine processing of high-temperature sensitive materials, improving cutting accuracy. This not only improves the overall cutting accuracy of the precision injection molded parts cutting device, but also expands its application range. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The device shown is a cutting device for precision injection molded parts, including a cutting table 1 for placing the body of the precision injection molded part;

[0027] The processing fence 2 is threadedly connected to the top of the cutting table 1 to limit the cutting range. Cutting openings 3 are provided on both sides of the top of the cutting table 1. The cutting machine body 4 is fixedly installed on the outer sides of the processing fence 2, and the drive controller 5 is fixedly installed on the outside of the cutting machine body 4.

[0028] Servo motor 6 is fixedly installed inside the cutting machine body 4. A rotating rod 7 is fixedly connected to the output end. A cutting blade 8 is fixedly installed at the other end of the rotating rod 7. An electromagnetic induction coil 9 is fixedly installed on the outside of the cutting blade 8. Thermocouple sensors 10 are fixedly installed on the upper and lower sides of the outside of the cutting blade 8.

[0029] The longitudinal electric slide rail 15 is fixedly installed on both sides of the outer side of the processing enclosure 2, and is used to externally slide and connect the longitudinal electric slide sleeve 16. The gantry frame 17 is fixedly installed on the outside of the longitudinal electric slide sleeve 16. The transverse electric slide rail 18 is fixedly installed on the top of the gantry frame 17. The transverse electric slide sleeve 19 is slidably connected to the outside of the transverse electric slide rail 18. The laser cutting head 20 is fixedly installed at the bottom of the transverse electric slide sleeve 19. The laser 21 is fixedly installed on the outside of the gantry frame 17. If it is necessary to perform fine cutting on the surface of the precision injection molded part, the longitudinal electric slide rail 15 and the transverse electric slide rail 18 can drive the laser cutting head 20 to emit laser light, and use the laser to complete the fine cutting of the precision injection molded part.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the processing enclosure 2 is threadedly connected to the cutting table 1. The cutting blades 8 are symmetrically arranged around the central axis of the cutting table 1. The two cutting blades 8 can be selected at different cutting positions according to the cutting edge requirements of the precision injection molded parts, thereby reducing the clamping time of the precision injection molded parts. The lower end of the cutting blade 8 is rotatably connected in the cutting opening 3. The rotating rod 7 is integrated with the cutting blade 8. The overall structure of the cutting blade 8 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to perform timely maintenance.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, a push electric slide rail 11 is fixedly installed above the cutting table 1. A push electric slide sleeve 12 is slidably connected to the outside of the push electric slide rail 11. The cutting table 1 is driven forward by the push electric slide rail 11 to perform the cutting work. This eliminates the need for manual contact to push the precision injection molded parts to complete the cutting work, ensuring operational safety. A cutting plate 13 is fixedly installed above the push electric slide sleeve 12. Workpiece clamps 14 are threadedly connected to the top of the cutting plate 13. The workpiece clamps 14 can be adjusted in position according to the current size of the precision injection molded parts, thereby fixing different precision injection molded parts on the cutting plate 13 and assisting in the cutting. The gantry frame 17 is slidably connected to the cutting table 1. The laser cutting head 20 is vertically distributed with the cutting table 1, allowing the longitudinal electric slide rail 15 and the transverse electric slide rail 18 to drive the laser cutting head 20 to emit laser light, using the laser to complete the fine cutting of the precision injection molded parts.

[0032] The working principle of this utility model is as follows: First, connect the external power supply, take out the precision injection molded part that needs to be cut, and place the precision injection molded part on the cutting plate 13. Then, adjust the position of the workpiece clamp 14 on the cutting plate 13 according to the size of the precision injection molded part, so that the workpiece clamp 14 fixes the precision injection molded part, exposing the side to be cut on the outside of the cutting plate 13. Then, due to the precision requirements of cutting the precision injection molded part, different cutting methods can be selected according to different precision injection molded parts. The electromagnetic induction coil 9 is energized to provide... The cutting blade 8 is heated, causing its edge to heat up through heat transfer. The servo motor 6 then drives the cutting blade 8 to rotate. A thermocouple sensor 10 located outside the cutting blade 8 transmits the blade temperature to the drive controller 5 in real time, allowing external operators to control the temperature of the cutting blade 8. The electric guide rail 11 then moves the precision injection molded part close to the cutting blade 8 to complete the thermal cutting, resulting in a smooth cut and reduced residue. If further fine cutting is needed on the surface of the precision injection molded part, the longitudinal... The electric slide rail 15 and the transverse electric slide rail 18 drive the laser cutting head 20 to move. Then, the laser 21 connects to the laser cutting head 20, causing the laser cutting head 20 to emit laser light. The laser is used to complete the fine cutting of the precision injection molded part. This gives the precision injection molded part cutting device two different cutting modes, which can switch between different modes for different precision injection molded parts. The hot knife mode is suitable for large-area cutting of thermoplastic materials, reducing cutting costs, while the laser mode can be used for fine processing of high-temperature sensitive materials, improving cutting accuracy. After the precision injection molded part is cut, the cutting precision injection molded part is pushed back by the push electric slide rail 11 to complete the entire cutting work. Finally, after completing the installation and use of the precision injection molded part cutting device according to the above operations, turn off the switch of the servo motor 6, the switch of the electromagnetic induction coil 9, the switch of the push electric slide rail 11, and the switches of the longitudinal electric slide rail 15 and the transverse electric slide rail 18. If it is not used for a long time, simply disconnect the external power supply. This completes the use of the precision injection molded part cutting device.
