[0018] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0019] Please refer to Figures 1 to 3 , for achieving the above purposes, the present utility model provides the following technical solutions:

[0020] A thread tapping device for machining automotive die parts, including a base 1, where a fixed plate 2 is provided at the upper end of the base 1; a telescopic cylinder 3 is provided above the fixed plate 2, and a support table 4 is provided at one end of the fixed plate 2 away from the telescopic cylinder 3; a limit chute 5 is opened at the upper end of the support table 4, and a slide block 6 is provided in the limit chute 5; the top end of the piston rod of the telescopic cylinder 3 extends towards the side of the slide block 6, and the top end of the piston rod is fixedly connected to the slide block 6 through a floating joint 7; a limit block 8 is provided on one side of the fixed plate 2 close to the support table 4, and a blanking hole 9 penetrating the fixed plate 2 is opened between the support table 4 and the limit block 8; a first fixed clamping groove 10 is opened on one side of the slide block 6 close to the limit block 8, and a second fixed clamping groove 11 adapted to the first fixed clamping groove 10 is opened on one side of the limit block 8, and the heights of the first fixed clamping groove 10 and the second fixed clamping groove 11 are equivalent; mounting seats 12 are arranged side by side on one side of the base 1, and a thread tapping assembly 13 is provided at the upper end of the mounting seat 12.

[0021] By placing the mold part to be processed in the first fixed clamping groove 10, ensure that the part is placed stably and matches the size of the first fixed clamping groove 10; start the telescopic cylinder 3 to control the piston rod to extend, and push the slider 6 to move towards the limiting block 8 in the limiting sliding groove 5 through the floating joint 7. When the slider 6 moves, the first fixed clamping groove 10 approaches the second fixed clamping groove 11 until the two are closely attached, so as to firmly clamp the part between the first fixed clamping groove 10 and the second fixed clamping groove 11; after the part is fixed, start the tapping assembly 13, and the servo motor 1302 in the tapping assembly 13 drives the lead screw linear slide 1301 to move, driving the tapping machine 1304 to move towards the part, so that the tapping head 1306 connected to the output end of the tapping machine 1304 is aligned with the position on the part that needs to be tapped, and start the tapping operation; after the tapping is completed, the servo motor 1302 drives the tapping machine 1304 to return to the original position, and the piston rod of the telescopic cylinder 3 retracts and drives the slider 6 to retract, so that the first fixed clamping groove 10 and the second fixed clamping groove 11 release the part; the processed part falls into the receiving box 21 below the base 1 through the blanking hole 9; repeat the above steps to perform tapping processing on the next mold part; through the above work content, the tapping device for processing automotive mold parts can efficiently and accurately complete the tapping processing task of mold parts.

[0022] Please refer to Figure 2 , as an embodiment of the present invention, the tapping assembly 13 includes a lead screw linear slide 1301, one end of the lead screw linear slide 1301 is fixedly connected with a servo motor 1302; a tapping machine 1304 is arranged on the slide seat 1303 of the lead screw linear slide 1301, and the tapping machine 1304 is fixedly connected with the slide seat 1303 through a fixed hoop 1305; a tapping head 1306 is connected to the output end of the tapping machine 1304, the tapping head 1306 is arranged opposite to the first fixed clamping groove 10, and the horizontal height of the tapping head 1306 is equivalent to the horizontal height of the first fixed clamping groove 10.

[0023] In the above-described solution, the tapping machine 1304 is stably fixed on the slide 1303 of the lead screw linear slide 1301 by the fixed ferrule 1305; then the servo motor 1302 is started, and the lead screw linear slide 1301 is driven by the servo motor 1302 to perform precise linear motion; by controlling the rotation direction and speed of the servo motor 1302, the slide 1303 is adjusted to drive the tapping machine 1304 to move on the lead screw linear slide 1301, ensuring that the position of the tapping head 1306 is aligned with the first fixed slot 10, and the horizontal height of the tapping head 1306 is equivalent to the horizontal height of the first fixed slot 10, so as to perform accurate tapping operations; when the slider 6 cooperates with the limit block 8 to firmly clamp the part between the first fixed slot 10 and the second fixed slot 11, the tapping machine 1304 is started; the output end of the tapping machine 1304 drives the tapping head 1306 to rotate and starts to move forward to perform tapping on the part; during the tapping process, the servo motor 1302 continuously provides stable power to ensure that the tapping head 1306 rotates and moves at a constant speed and force; after the tapping is completed, the tapping head 1306 stops rotating and moves upward to leave the surface of the part; after the tapping head 1306 completes the tapping operation, the servo motor 1302 drives the lead screw linear slide 1301 to drive the slide 1303 to move, so that the slide 1303 drives the tapping machine 1304 back to the initial position; after waiting for the next part to be clamped between the first fixed slot 10 and the second fixed slot 11, the above tapping operation is repeated; through the above work content, the tapping assembly 13 can efficiently and accurately complete the tapping processing task of automotive mold parts, improve production efficiency, and ensure processing quality.

[0024] Please refer to Figure 2 , as an embodiment of the present invention, limit sliders 14 are respectively provided at the lower ends of both sides of the slide 1303, and limit guide rails 15 adapted to the limit sliders 14 are provided at the upper end of the mounting base 12.

[0025] In the above-described solution, when the servo motor 1302 drives the lead screw linear slide 1301 to drive the slide seat 1303 to perform linear motion, the limit slider 14 slides within the limit guide rail 15; the limit guide rail 15 provides a stable motion trajectory for the limit slider 14, ensuring that the slide seat 1303 drives the tapping machine 1304 to move precisely along a predetermined path; the design of the limit slider 14 and the limit guide rail 15 limits the motion range of the slide seat 1303. When the slide seat 1303 moves to the extreme position, the limit slider 14 will contact the end of the limit guide rail 15, thereby preventing the slide seat 1303 from moving further. This helps to prevent the slide seat 1303 from detaching from the lead screw linear slide 1301 or colliding with other components during the motion; the contact between the limit slider 14 and the limit guide rail 15 increases the stability of the slide seat 1303 during the motion. Even under high-speed motion or external interference, the slide seat 1303 can maintain a stable motion state, ensuring the accuracy of the tapping operation; the sliding contact between the limit slider 14 and the limit guide rail 15 uses wear-resistant materials, reducing wear during long-term motion. This helps to extend the service life of the tapping assembly 13 and reduce failures caused by wear.

[0026] Please refer to Figure 3 , as an embodiment of the present utility model, the lower end of the first fixed card slot 10 extends forward and is provided with a supporting plate 16, and a baffle 17 is provided above one end of the supporting plate 16.

[0027] In the above-described solution, the supporting plate 16 extends forward from the lower end of the first fixed card slot 10, providing a stable supporting surface for the automotive mold parts placed therein; during the tapping process of the parts, the bottom of the parts contacts the supporting plate 16, ensuring that the parts will not move or tilt in the vertical direction due to gravity or tapping force; the supporting plate 16 and the first fixed card slot 10 jointly form a clamping space for the parts, restricting the movement of the parts in the horizontal direction; the baffle 17 is located above one end of the supporting plate 16, further restricting the position of the parts during the tapping process, ensuring that the parts will not deviate from the predetermined position due to vibration or external force; the design of the supporting plate 16 and the baffle 17 helps to protect the parts from damage during the processing, preventing the parts from slipping or colliding with other components due to unstable clamping during tapping, thereby reducing the risk of part damage or scrapping. This flexibility enables the tapping device to process various types of parts, improving the versatility and production efficiency of the equipment.

[0028] Please refer to Figure 1 , as an embodiment of the present utility model, a support frame 18 is provided at one end of the fixing plate 2 close to the telescopic cylinder 3, and a storage box 19 is provided at the upper end of the support frame 18; the discharge end of the storage box 19 is connected with an arc-shaped material guiding groove 20, and the lower end of the arc-shaped material guiding groove 20 is arranged above the first fixed card slot 10; a receiving box 21 is provided below the base 1, and the receiving box 21 is arranged directly below the blanking hole 9.

[0029] In the above-described solution, the storage box 19 is located at the upper end of the support frame 18 and is used to store automotive mold parts to be processed. When feeding is required, the parts in the storage box 19 move to the discharge end under the action of gravity or through other auxiliary mechanisms; the arc-shaped material guide groove 20 is connected to the discharge end of the storage box 19 and is used to guide the parts above the first fixed card slot 10; the parts slide down along the arc-shaped material guide groove 20 and finally fall into the first fixed card slot 10 to prepare for tapping operation; after the parts fall into the first fixed card slot 10, the telescopic cylinder 3 will push the slider 6 to move, so that the parts are firmly clamped between the first fixed card slot 10 and the second fixed card slot 11; then start the tapping machine 1304 to perform tapping processing on the parts; after tapping is completed, the telescopic cylinder 3 drives the slider 6 to retract, so that the first fixed card slot 10 on the slider 6 releases the parts, and the parts fall off from the first fixed card slot 10 under the action of gravity or through other auxiliary mechanisms (such as a blowing device); the parts directly fall into the receiving box 21 through the blanking hole 9 under the base 1, and the parts in the receiving box 21 can be taken out regularly for subsequent processing or packaging; the entire feeding, tapping, and blanking process can be carried out continuously to achieve automated production. When the parts in the storage box 19 are used up, they can be replenished in time to ensure the continuity of production; thus, the automatic feeding, tapping operation, and blanking process of automotive mold parts are realized, greatly improving the production efficiency and reducing the labor intensity of workers.
