Description

Technical Field

[0001] This utility model relates to the technical field of stamping die coating, specifically to a stamping die coating device. Background Technology

[0002] Die coating is an advanced surface treatment technology widely used in industrial production. This technology significantly improves the wear resistance and service life of the die by forming a high-hardness, low-friction coating on the die surface. Common coating materials include titanium, chromium, carbides, and diamond-like carbon.

[0003] According to Chinese Patent No. CN210261961U, a stamping die coating device includes a coating chamber and a servo motor. Vacuum exhaust pumps are installed on both sides of the coating chamber. A rotating shaft is installed at the bottom of the coating chamber, with support columns on both sides of the rotating shaft and a base at the bottom of the rotating shaft. A chamber door is installed on one side wall of the coating chamber. The servo motor is bolted to the base. A heat sink is installed on the top of the coating chamber. An electrical control box is installed on one side of the base. A support platform is installed on the top of the rotating shaft, with a spring clip on the top of the support platform. A molecular pump is installed on the inner wall of the coating chamber, and an ion pump is installed opposite the molecular pump. Target boxes are installed on both the molecular pump and the ion pump. A heater is installed at the top of the coating chamber.

[0004] In the above solution, the spring clamp is used to fix the mold on the placement table, which still has the following disadvantages: after the spring clamp holds the mold, when the mold is rotating for coating, the spring clamp may cause the mold to shake during coating due to the inertia of the mold during rotation and its own retractable characteristics, which reduces the firmness of the mold during coating. Utility Model Content

[0005] The purpose of this invention is to provide a stamping die coating device to solve the problem that when the die is rotating for coating, the spring clip may cause the die to shake during coating due to the inertia of the die during rotation and its own retractable characteristics, thus reducing the firmness of the die during coating.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a stamping die coating device, including a placement platform, the placement platform being rotatably disposed on the top surface of a base plate, a sliding groove being provided on the top surface of the placement platform, a bidirectional lead screw being rotatably inserted inside the sliding groove, two sliding plates being threadedly connected to the bidirectional lead screw, the sliding plates being slidably disposed with respect to the sliding groove, an extrusion plate being fixed on the top surface of the sliding plate, and anti-slip pads being fixed on the two sides of the two extrusion plates that are close to each other.

[0007] Preferably, the surface of the placement platform has two rotating grooves, and one end of each rotating groove has a rotating hole. The rotating hole is rotatably inserted into a bidirectional lead screw, and both ends of the bidirectional lead screw are fixed with turntables. The turntables are rotatably arranged with the rotating grooves.

[0008] Preferably, the top surface of the base plate is detachably provided with a coating chamber, the top surface of the base plate is provided with a fixing groove, the inside of the fixing groove is fixed with an elastic frame, the four sides of the coating chamber are respectively fixed with connecting plates, the top surface of the base plate is provided with a plurality of threaded grooves, and a fixing bolt is rotatably inserted into the connecting plate, the bottom end of the fixing bolt passes through the connecting plate and is threadedly connected to the threaded groove.

[0009] Preferably, the top surface of the base plate is provided with a mounting groove, and a motor is fixed inside the mounting groove. The top end of the motor output shaft is fixed to the bottom surface of the placement platform.

[0010] Preferably, a baffle plate is fixed inside the sliding groove, and a sliding opening is provided on one side of the sliding plate, and the sliding opening is slidably inserted into the baffle plate.

[0011] Preferably, rotating bars are fixed on opposite sides of the two turntables, and a sliding groove is provided on one side of each rotating bar. A limiting plate is slidably provided inside the sliding groove, and a plurality of limiting grooves are provided on the inner wall of the rotating groove. The limiting grooves and the limiting plate are slidably configured.

[0012] Compared with the prior art, the stamping die coating device using the above technical solution has the following advantages:

[0013] 1. Before coating the mold, the operator will first drive the double-ended lead screw to rotate inside the rotating hole through the turntable. When the double-ended lead screw rotates, it will drive the sliding plate to slide inside the sliding groove through the threaded connection with the sliding plate. This will drive the two sliding plates to move towards the mold on the placement table. As the distance between the two sliding plates decreases, the anti-slip pad will be pressed against the surface of the mold, which will fix the mold on the top surface of the placement table and increase the stability of the mold during coating.

[0014] 2. After the mold is fixed on the placement table, the staff will attach the coating chamber to the top surface of the base plate and use various equipment inside the coating chamber, such as vacuum exhaust pump, ion pump, molecular pump, etc., to coat the mold. At this time, the bottom surface of the coating chamber will be in contact with the top surface of the elastic frame. Then the staff will pass the fixing bolt through the connecting plate and screw it into the inside of the threaded groove. The compression and adhesion between the coating chamber and the elastic frame will increase the sealing between the base plate and the coating chamber.

[0015] 3. When the operator rotates the turntable to drive the bidirectional lead screw to rotate synchronously, the rotating bar will apply a rotational force to the turntable. After the mold is clamped and fixed on the placement table, the operator will push the limiting plate out of the sliding groove and slide it into the interior of the limiting groove, which can lock the bidirectional lead screw. When the sliding plate slides, it will drive the sliding port to slide on the surface of the baffle plate, which can block the bidirectional lead screw from the top of the baffle plate, preventing the bidirectional lead screw from being contaminated with coating during the coating process, and preventing it from affecting the threaded connection between the bidirectional lead screw and the sliding plate.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, a stamping die coating device includes a placement platform 2, which is rotatably mounted on the top surface of a base plate 1. A sliding groove 3 is provided on the top surface of the placement platform 2. A bidirectional lead screw 4 is rotatably inserted inside the sliding groove 3. Two sliding plates 5 are threaded onto the bidirectional lead screw 4. The sliding plates 5 are slidably mounted on the sliding groove 3. An extrusion plate 6 is fixed on the top surface of the sliding plate 5. Anti-slip pads 7 are fixed on the two sides of the two extrusion plates 6 that are close to each other. Two rotating grooves 8 are provided on the surface of the placement platform 2. A rotating hole 9 is provided at one end of the rotating groove 8. The rotating hole 9 is rotatably inserted into the bidirectional lead screw 4. Turntables 10 are fixed at both ends of the bidirectional lead screw 4. The turntables 10 are rotatably mounted on the rotating grooves 8.

[0023] During use, before coating the mold, the operator will first drive the bidirectional lead screw 4 to rotate inside the rotating hole 9 via the turntable 10. When the bidirectional lead screw 4 rotates, it will drive the sliding plate 5 to slide inside the sliding groove 3 through the threaded connection with the sliding plate 5. This will drive the two sliding plates 5 to move towards the mold on the placement table 2. As the distance between the two sliding plates 5 decreases, the anti-slip pad 7 will be pressed against the surface of the mold, thus fixing the mold on the top surface of the placement table 2 and increasing the stability of the mold position during coating.

[0024] like Figure 1 and Figure 2 As shown, a coating chamber 11 is detachably mounted on the top surface of the base plate 1. A fixing groove 12 is provided on the top surface of the base plate 1, and an elastic frame 13 is fixed inside the fixing groove 12. Connecting plates 14 are fixed on the four sides of the coating chamber 11. Several threaded grooves 15 are provided on the top surface of the base plate 1. Fixing bolts 16 are rotatably inserted into the connecting plates 14. The bottom end of the fixing bolts 16 passes through the connecting plates 14 and is threadedly connected to the threaded grooves 15. An installation groove 19 is provided on the top surface of the base plate 1. A motor 20 is fixed inside the installation groove 19. The top end of the output shaft of the motor 20 is fixed to the bottom surface of the placement platform 2.

[0025] In use, after the mold is fixed on the placement platform 2, the operator will attach the coating chamber 11 to the top surface of the base plate 1 and use various equipment inside the coating chamber 11, such as vacuum exhaust pump, ion pump, molecular pump, etc., to coat the mold. At this time, the bottom surface of the coating chamber 11 will be in contact with the top surface of the elastic frame 13. Then the operator will pass the fixing bolt 16 through the connecting plate 14 and screw it into the threaded groove 15. The compression and contact between the coating chamber 11 and the elastic frame 13 will increase the sealing between the base plate 1 and the coating chamber 11.

[0026] like Figure 3 and Figure 4 As shown, a baffle plate 17 is fixed inside the sliding groove 3, and a sliding opening 18 is provided on one side of the sliding plate 5. The sliding opening 18 and the baffle plate 17 are slidably inserted. Rotating bars 21 are fixed on the two opposite sides of the two turntables 10. A sliding groove 22 is provided on one side of the rotating bar 21. A limiting plate 23 is slidably arranged inside the sliding groove 22. Several limiting grooves 24 are provided on the inner wall of the rotating groove 8. The limiting grooves 24 and the limiting plate 23 are slidably arranged.

[0027] During use, when the operator rotates the turntable 10 to drive the bidirectional lead screw 4 to rotate synchronously, the rotating bar 21 will apply a rotational force to the turntable 10. After the mold is clamped and fixed on the placement table 2, the operator will push the limiting plate 23 out of the sliding groove 22 and slide it into the inside of the limiting groove 24, which can lock the bidirectional lead screw 4. When the sliding plate 5 slides, it will drive the sliding port 18 to slide on the surface of the shielding plate 17, which can shield the bidirectional lead screw 4 from the top of the bidirectional lead screw 4, preventing the bidirectional lead screw 4 from being contaminated with coating during the coating process, and preventing it from affecting the threaded connection between the bidirectional lead screw 4 and the sliding plate 5.
