Description

Technical Field

[0001] The present invention relates to the technical field of die processing, and particularly relates to a processing device and a processing method for a die-casting die. Background Art

[0002] During the long-term use of a die-casting die, the guide pillar holes at the four corners are prone to wear, deformation or position deviation due to the repeated action of high pressure, high speed, high temperature, as well as friction and impact during the mold opening and closing movement, resulting in an increase or unevenness in the clearance between the guide pillar and the guide hole, thereby affecting the positioning accuracy and guiding stability of the die. If the guide pillar holes are not repaired in time, it may cause increased unilateral wear of the guide pillar, movement jamming, positioning deviation, and even problems such as misalignment of the die parting surface, flash or burrs on the product. In severe cases, it may cause the guide pillar to break or damage the overall structure of the die. By milling to repair the guide pillar holes, the dimensional accuracy and geometric shape can be restored, ensuring a reasonable clearance between the guide pillar and the guide hole, eliminating the unbalanced force caused by hole position deviation or deformation, thereby ensuring smooth mold opening and closing actions, accurate positioning, extending the service life of the die and maintaining the consistency of product quality.

[0003] In the patent with the Chinese patent publication number CN117754299B, a processing device for an ultra-large integrated die-casting die is disclosed. In this invention, when the guiding member moves upward through the receiving plate, the telescopic rod cooperates with the guiding groove to drive the fixed seat to deflect by ninety degrees each time, thereby ensuring the accuracy of the repair milling position and angle of the next guide pillar hole, and thus helping to improve the processing accuracy and consistency, and reducing errors and deviations. However, this technical solution still has the following defects: 1. Driving the fixed seat to deflect by ninety degrees each time can only repair the guide pillar holes at the four corners of the die one by one, thus affecting the overall processing efficiency; 2. It can only adapt to the processing of a single model of die, thus affecting the applicability of the processing. Summary of the Invention

Compared with the traditional processing method of processing each hole position one by one, the milling mechanism controls the four groups of reamers to simultaneously complete the processing and repair of the hole positions. This synchronous operation mode not only greatly improves the processing efficiency but also eliminates the cumulative error generated by step-by-step processing. The four groups of reamers maintain exactly the same rotational speed and feed rate during rotary cutting, facilitating the meeting of the repair requirements of high-precision molds.

Detailed Embodiment

[0021] The following describes the detailed embodiment of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed embodiment.

[0022] Such as Figures 1 - 10As shown, the present invention is a processing equipment for a die-casting mold, including a processing table 1 and a frame 2 above it, an adsorption positioning mechanism 3 is installed between the frame 2 and the processing table 1, and a centering clamping mechanism 4 is installed on the frame 2, and a milling mechanism 6 for synchronously repairing the four corner guide column holes of the mold body 5 is also installed on the frame 2; the milling mechanism 6 includes a cross piece 61, a sliding piece 62, a rotating piece 64 with a reamer 63, a linkage assembly 65, a first telescopic rod 66, a driving assembly 67 and a lifting assembly 68, the first telescopic rod 66 is rotatably arranged between the cross piece 61 and the frame 2, the driving assembly 67 is used to drive the four sliding pieces 62 to slide synchronously along the cross piece 61, the rotating piece 64 is rotatably connected to the sliding piece 62, the cross piece 61 and the frame 2 are connected by the lifting assembly 68, and when the first telescopic rod 66 rotates, the rotating piece 64 is driven to rotate by the linkage assembly 65.

[0023] It should be noted that in the prior art, the outer cross-section of the die-casting mold is usually designed to be a square structure because the square structure can evenly disperse the high pressure generated during the die-casting process when subjected to force, reducing the risk of mold deformation or cracking caused by stress concentration. In this embodiment, the cross-sections of the mold body 5 and the frame 2 are both square structures. When the center lines of the mold body 5 and the frame 2 coincide with each other, the diagonal line of the frame 2 will be on the same vertical plane as the diagonal line of the mold body 5. At the same time, the center line connecting the two diagonal guide post holes of the mold body 5 will coincide with the diagonal line of the mold body 5. During use, the frame 2 is lifted to the top of the mold body 5, and then the frame 2 is slowly lowered so that the mold body 5 is located on the inner side of the frame 2 until the frame 2 is placed on the processing table 1, and then the centering clamping mechanism 4 is started to clamp the mold body 5. During the clamping process, the position of the frame 2 is adaptively adjusted to the center so that the diagonal of the frame 2 after the centering adjustment and the diagonal of the mold body 5 are located on the same vertical plane. Then the driving assembly 67 is started to drive the four sliding members 62 to slide synchronously along the cross member 61, so that the four groups of reamers 63 can move along the diagonal trajectory of the mold body 5 until the reamers 63 correspond to the four corner guide column holes of the mold body 5. Finally, the four first telescopic rods 66 are controlled to rotate synchronously, and the linkage assembly 65 is used to conveniently drive the four groups of reamers 63 to rotate synchronously. At the same time, the lifting assembly 68 is used to control the cross member 61 to move downward, so that the four groups of reamers 63 can perform synchronous repair processing on the four corner guide column holes of the mold body 5.

[0024] like Figure 3 and Figure 6As shown, the cross member 61 includes a pillar 612 with a through slot 611, an annular plate 613 and a hanging ring 614. The annular plate 613 is located directly above the center of the frame 2. The four pillars 612 are evenly distributed along the circumference of the annular plate 613, and the pillars 612 are located directly above the diagonal of the frame 2. The through slot 611 is opened through the pillar 612, and the hanging ring 614 is installed on the top of the pillar 612 away from the annular plate 613.

[0025] It should be noted that the angle between two adjacent pillars 612 is 90 degrees, and the extension lines of the two pillars 612 set at intervals coincide with each other. If angle bisectors are set at the four corners of the frame 2, then the center lines of the four pillars 612 along their length directions in this embodiment correspond one-to-one to the angle bisectors at the four corners of the frame 2, and the center lines of the pillars 612 along their length directions are located directly above the corresponding angle bisectors. The lifting ring 614 in this embodiment is convenient for connecting the lifting rope, and cooperates with external lifting equipment to facilitate lifting the frame 2 as needed.

[0026] like Figure 3 and Figures 6 - 7 As shown, the sliding member 62 includes a sliding frame 621 and a U-shaped block 622. The sliding frame 621 is set through the through slot 611. The two U-shaped blocks 622 are symmetrically arranged on the opposite side walls of the sliding frame 621, and the U-shaped blocks 622 are slidingly connected to the side of the pillar 612. The rotating member 64 is set through the bottom of the sliding frame 621, and the rotating member 64 is rotatably connected to the bottom of the sliding frame 621.

[0027] It should be noted that the bottom end of the rotating member 64 is coaxially connected to the reamer 63 through an adapter. The adapter is used to facilitate the replacement of the corresponding reamer 63 according to processing needs. This is a prior art and will not be elaborated here. In this embodiment, the central axis of the reamer 63 and the center line of the support 612 along its length direction are on the same vertical plane, and the two are perpendicular to each other. That is to say, when the sliding member 62 drives the reamer 63 to move, the reamer 63 moves along the diagonal direction of the mold body 5.

[0028] like Figure 3 and Figure 5 As shown, the drive assembly 67 includes a first motor 671, a first screw rod 672, a screw slider 673 and a connecting rod 674. The first motor 671 is installed at the top center of the cross member 61, the first screw rod 672 is coaxially connected to the output end of the first motor 671, the screw slider 673 is threadedly connected to the first screw rod 672, one end of the connecting rod 674 is hinged to one side of the screw slider 673, and the other end of the connecting rod 674 is hinged to the top of the corresponding sliding member 62.

[0029] It should be noted that the first motor 671 can control the first screw rod 672 to rotate forward and reverse. This is a prior art and will not be described in detail here. The sliding member 62 can only move along the support 612 (such asFigure 6 Slide in the length direction as shown in the figure, and cooperate with the articulated connecting rod 674 to conveniently limit the rotational freedom of the lead screw slider 673, so that only by controlling the rotation of the first lead screw 672, the four sliding members 62 can be driven to slide synchronously along the support column 612.

[0030] As Figures 2 - 4 As shown in the figure, the linkage assembly 65 includes a second telescopic rod 651, a driving bevel gear 652, a driven bevel gear 653, a first bevel gear 654 and a second bevel gear 655. The second telescopic rod 651 is rotatably connected to the support column 612, and the second telescopic rod 651 is distributed along the length direction of the support column 612. The driven bevel gear 653 is sleeved on the outer rod of the second telescopic rod 651. The driving bevel gear 652 is sleeved on the inner rod of the first telescopic rod 66, and the driving bevel gear 652 meshes with the driven bevel gear 653. The second bevel gear 655 is located in the sliding frame 621, and the second bevel gear 655 is coaxially connected to the top end of the rotating member 64. The first bevel gear 654 is coaxially connected to the inner rod of the second telescopic rod 651, and the first bevel gear 654 meshes with the second bevel gear 655.

[0031] It should be noted that limit keys are provided on the inner rods of the first telescopic rod 66 and the second telescopic rod 651 in this embodiment, and key grooves for the limit keys to slide are provided on the inner wall of the outer rods of the first telescopic rod 66 and the second telescopic rod 651. That is to say, when the outer rods of the first telescopic rod 66 and the second telescopic rod 651 rotate, they can synchronously drive the inner rods to rotate. The top end of the inner rod of the first telescopic rod 66 is rotatably connected to the bottom of the support column 612 (as Figure 6 shown in the figure) through a first bearing. An annular groove corresponding to the outer rod of the first telescopic rod 66 is opened at the top of the frame body 2, and the outer rod of the first telescopic rod 66 is rotatably connected to the annular groove through a second bearing; When the first telescopic rod 66 rotates, it will drive the driving bevel gear 652, and it is convenient to drive the second telescopic rod 651 to rotate by using the driven bevel gear 653. The second telescopic rod 651 drives the rotating member 64 connected with the second bevel gear 655 to rotate through the first bevel gear 654, and then drives the reamer 63 to rotate. That is to say, by controlling the four first telescopic rods 66 to rotate synchronously, the four groups of reamers 63 can be driven to rotate synchronously, which is convenient for synchronously repairing the corner guide post holes of the mold body 5 at one time. In this embodiment, the rotating member 64 and the bottom of the sliding frame 621 (as Figure 7 shown in the figure) are rotatably connected through a third bearing.

[0032] As Figures 2 - 3As shown, the lifting assembly 68 includes a second motor 681, a second lead screw 682, and a reinforcing column 683. The reinforcing column 683 is connected between two adjacent support columns 612. The second motor 681 is installed on the top edge of the frame body 2. The second lead screw 682 is coaxially connected to the second motor 681. One of the reinforcing columns 683 is threadedly sleeved on the second lead screw 682.

[0033] It should be noted that the second motor 681 can control the forward and reverse rotation of the second lead screw 682. This is prior art and will not be elaborated here. Setting the reinforcing column 683 between two adjacent support columns 612 is beneficial to improving the overall structural strength of the cross member 61, making it not easily break. The first telescopic rod 66 limits the rotational freedom of the cross member 61, so that when the second lead screw 682 rotates, it can drive the reinforcing column 683 threadedly sleeved on it to move up and down, thereby realizing the overall lifting of the cross member 61, and further facilitating driving the reamer 63 to extend into the corner guide holes of the mold body 5 for repair processing.

[0034] As Figure 3 and Figure 8 shown, the milling mechanism 6 further includes a rotating assembly 69 for driving the first telescopic rod 66 to rotate. The rotating assembly 69 includes a third motor 691, a double-slot sprocket 692, a first chain 693, and a second chain 694. The third motor 691 is installed on the top edge of the frame body 2. The double-slot sprockets 692 are respectively sleeved on the output shaft of the third motor 691 and the outer rod of the first telescopic rod 66. The double-slot sprocket 692 on the third motor 691 is connected to the double-slot sprocket 692 on one of the first telescopic rods 66 through the first chain 693, and the double-slot sprockets 692 on the first telescopic rods 66 are sequentially connected through the second chain 694.

[0035] It should be noted that starting the third motor 691 drives the corresponding double-slot sprocket 692 to rotate. The first chain 693 on this double-slot sprocket 692 will drive the corresponding first telescopic rod 66 to rotate. The adjacent first telescopic rods 66 are driven by the double-slot sprockets 692 and the second chain 694, so as to facilitate the synchronous rotation of the four first telescopic rods 66.

[0036] As Figure 1 and Figure 9 shown, the adsorption and positioning mechanism 3 includes balls 31, suction cups 32, a hose 33, and a hollow adsorption frame 34. The adsorption frame 34 is installed at the bottom of the frame body 2. A plurality of balls 31 are rotatably installed at the bottom of the adsorption frame 34, and the adsorption frame 34 is in rolling connection with the top of the processing table 1 through the balls 31. The suction cups 32 are arranged at intervals between adjacent balls 31, and the inner cavities of the suction cups 32 are communicated with the inner cavity of the adsorption frame 34. The hose 33 is communicatively arranged on one side of the adsorption frame 34.

[0037] It should be noted that a ball groove for the rolling of the balls 31 is provided at the bottom of the adsorption frame 34 in this embodiment. It should be noted that the ball groove is not communicated with the inner cavity of the adsorption frame 34, and the lowest point of the balls 31 is on the same plane as the bottom of the suction cup 32. The hose 33 is connected to an external negative pressure device. When the negative pressure device is not operating, the suction cup 32 does not adsorb the processing table 1. That is to say, at this time, the balls 31 are used to facilitate the movement of the whole frame body 2 and the adsorption frame 34 along the surface of the processing table 1. When the negative pressure device operates, the suction cup 32 adsorbs the processing table 1. That is to say, at this time, due to the adsorption and positioning of the suction cup 32, it is convenient to lock the position of the frame body 2 on the processing table 1 to prevent it from displacing.

[0038] As Figure and ​ shown, the centering clamping mechanism 4 includes clamping plates 41, sliding columns 42, electric sliders 43 and electric slide rails 44. Grooves for receiving the clamping plates 41 are provided on the inner side walls of the frame body 2. One end of the sliding column 42 is connected to the clamping plate 41, and the other end of the sliding column 42 slides through the bottom of the groove and extends outwards. The electric slide rail 44 is installed on the outer side wall of the frame body 2 and is located below the sliding column 42. The electric slider 43 is slidably arranged on the electric slide rail 44, and the electric slider 43 is connected to the end of the sliding column 42 far from the clamping plate 41.

[0039] It should be noted that in this embodiment, the two electric slide rails 44 on the opposite side walls of the frame body 2 are in a group. That is to say, the four electric slide rails 44 are divided into two groups in total. It should be noted that the electric sliders 43 on each group of two electric slide rails 44 need to slide synchronously towards or away from each other. When the electric slider 43 slides along the electric slide rail 44, it will drive the corresponding sliding column 42 to slide. In the initial state, control the two clamping plates 41 of the first group to slide synchronously towards each other. During this process, when touching the mold body 5, the frame body 2 can be aligned in one direction. Similarly, control the two clamping plates 41 of the second group to slide synchronously towards each other. During this process, when touching the mold body 5, the frame body 2 can be aligned in the other direction, so that the diagonal of the frame body 2 and the diagonal of the mold body 5 are on the same vertical plane.

[0040] The embodiment of the present invention provides a processing method for a die-casting mold, including the following steps: Step 1: Lift the frame body 2 above the mold body 5, and then slowly lower the frame body 2 so that the mold body 5 is located inside the frame body 2 until the frame body 2 is placed on the processing table 1; Step 2: Use the centering clamping mechanism 4 to adaptively clamp the mold body 5, and automatically correct the position of the frame body 2 during the clamping process to make the center of the frame body 2 coincide with the center of the mold body 5, and then use the adsorption positioning mechanism 3 to perform negative pressure positioning on the frame body 2; Step 3: Start the driving component 67 to drive the four sliding parts 62 to slide synchronously along the cross-shaped part 61 until the reamer 63 on the rotating part 64 driven by the sliding part 62 corresponds to the four-corner guide pillar holes of the mold body 5; Step 4: Drive the first telescopic rod 66 to rotate synchronously. During the rotation process, use the linkage component 65 to drive the reamer 63 on the rotating part 64 to rotate. At the same time, use the lifting component 68 to drive the cross-shaped part 61 to move, so that the rotating reamer 63 is inserted into the four-corner guide pillar holes of the mold body 5, and the four-corner guide pillar holes of the mold body 5 can be repaired synchronously at one time.

[0041] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
