Description

Technical Field

[0001] The present invention relates to the technical field of mold processing, in particular to a high-efficiency intelligent positioning system for injection mold frame processing. Background Art

[0002] A mold is a widely used industrial tool. A mold is a tool used to make molded objects. During injection molding, blow molding, and die casting, two molds need to be closed. To ensure the processing effect, the upper and lower surfaces of the mold need to be polished during production to avoid burrs on the upper and lower surfaces of the mold that may prevent the mold from being completely sealed.

[0003] In order to ensure the accuracy of the mold's grinding thickness in the existing technology, the mold is placed on a workbench inclined at 45 degrees before grinding to avoid reflective shadows on the right-angled surfaces of the square mold, which may reduce the detection accuracy. However, when placing the mold, the mold is often not aligned with the set 45-degree angle contact end, resulting in a large error in the laser measuring instrument during detection. In addition, for some molds with relatively rough surfaces, even if the edge contacts the measurement point, the right-angle end may not contact in place due to the large friction, resulting in the mold size being measured too large, resulting in excessive subsequent grinding and an increased mold grinding scrap rate.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-8, the present invention provides an embodiment: an efficient intelligent positioning system for injection mold frame processing, comprising a workbench 1, a guide rail 11 is provided on the top of the workbench 1, and a placement rack 9 is provided on the upper limit sliding of the guide rail 11, and an inclined plate 8 is fixed on the top of the placement rack 9, and a first laser rangefinder 3, a second laser rangefinder 32 and a third laser rangefinder 33 are fixed on the top of the inclined plate 8, respectively, the inclined plate 8 is provided with a moving mechanism 5 for limited sliding, a center axis 4 is fixed at the end of the moving mechanism 5, two balancing mechanisms 2 are provided on the top of the inclined plate 8, a clamping mechanism 7 for judging whether the mold is in place is provided on the top of the inclined plate 8, and a rotating mechanism 6 is provided on the top of the moving mechanism 5, the clamping mechanism 7 includes a clamping assembly, an L-shaped baffle 78 and two L-shaped insertion rods 76, the clamping assembly is slidably arranged on the inclined plate 8, the L-shaped baffle 78 is fixedly arranged on the inclined plate 8, and the two L-shaped insertion rods 76 are movably plugged at both ends of the L-shaped baffle 78. First, place the square mold on the inclined plate 8. The mold contacts the clamping mechanism 7 under the action of gravity, forming a position parallel to the edge of the inclined surface. Then, the left and right balance of the mold is adjusted by the balancing mechanism 2. After the adjustment is completed, the center point of the mold is determined by the moving mechanism 5, thereby driving the rotating mechanism 6 to the center point of the mold. Then, the mold is rotated forty-five degrees by the rotating mechanism 6 and then put down. The mold contacts the inside of the clamping mechanism 7 under the action of gravity, so that the clamping mechanism 7 is unlocked. The mold drives the clamping mechanism 7 down to the measuring point due to the action of gravity. Then, the height, width and length are measured respectively by the first laser rangefinder 3, the second laser rangefinder 32 and the third laser rangefinder 33 to facilitate setting subsequent polishing parameters.

[0028] Specifically, the two balancing mechanisms 2 include a first gear 21, two end plates 22, two balancing springs 23, side columns 24, a first motor 25, and a second gear 26. The two end plates 22 are movably connected and inserted at the top of the inclined plate 8, and the side columns 24 are rotatably arranged between the two end plates 22. The first gear 21 is fixedly sleeved on the side columns 24, the first motor 25 is fixedly arranged inside the inclined plate 8, and the second gear 26 is fixedly arranged at the end of the output shaft of the first motor 25. The two balancing springs 23 are respectively fixedly arranged at the bottom of the two end plates 22. When the centerline of the mold is not on the central axis 4, the mold tilts to one side, driving the end plates 22 downward, and the ends drive the side columns 24 and the first gear 21 downward. The first gear 21 meshes with the second gear 26, and the first motor 25 drives the second gear 26 to rotate. The second gear 26 drives the first gear 21 to rotate, and the first gear 21 drives the side columns 24 to rotate. The side columns 24 drive the mold to move toward the other side column 24. This achieves automatic adjustment and balancing of the mold, is applicable to most regular polygon molds, and has a wide range of applications.

[0029] Specifically, the moving mechanism 5 includes a second motor 51, a transmission shaft 52, a third gear 53, an annular rack 54, a fourth gear 55, a U-shaped rack 56, two mounting plates 57 and a limiting assembly. The two mounting plates 57 are fixedly set on the top of the inclined plate 8, the second motor 51 is fixedly set on the side wall of the mounting plate 57, the transmission shaft 52 is fixedly set on the end of the output shaft of the second motor 51, the third gear 53 and the fourth gear 55 are both fixedly set on the transmission shaft 52, the annular rack 54 is limited and slidably set on the inclined plate 8, the U-shaped rack 56 is limited and slidably set on the inclined plate 8, and the inclined plate 8 is provided with a receiving groove at the bottom of the annular rack 54, and the limiting assembly is arranged inside the receiving groove. The transmission shaft 52 is driven to rotate by the second electric output shaft, and the transmission shaft 52 drives the third gear 53 and the fourth gear 55 to rotate synchronously. The third gear 53 and the fourth gear 55 respectively drive the annular rack 54 and the U-shaped rack 56 to move. It is worth noting that the transmission ratio of the third gear 53 to the fourth gear 55 is 2:1, so the distance moved by the annular rack 54 is twice that of the U-shaped rack 56.

[0030] Specifically, the limit assembly includes a limit spring 58, a pressure plate 59, an L-shaped limit rod 510, a fifth rack 511, a limit block 512, a resistance ring 513 and a spring column 514. The spring column 514 is plugged into the middle of the annular rack 54, the pressure plate 59 is fixed on the top of the spring column 514, and the pressure plate 59 is plugged into and matched with the annular rack 54. The L-shaped limit rod 510 is fixed at the bottom of the spring column 514, the resistance ring 513 is fixed on the spring column 514, the limit spring 58 is fixed at the bottom of the resistance ring 513, the fifth rack 511 is fixed inside the accommodating groove, and the limit block 512 is fixed at the top of the L-shaped resistance limit rod. The weight of the mold drives the pressure plate 59 to move downward, and the pressure plate 59 drives the resistance ring 513, the spring and the L-shaped limit rod 510 to move downward. The L-shaped limit rod 510 moves downward to drive the limit block 512 to disengage. When the annular rack 54 drives the pressure plate 59 to move to the edge of the mold, the pressure plate 59 is driven to reset under the action of the limit spring 58, and the resistance ring 513, the spring column 514 and the L-shaped limit rod 510 are synchronously reset, so that the limit block 512 is clamped at the fifth rack 511, thereby making the annular rack 54 and the U-shaped rack 56 unable to move; automatic positioning of the mold size is achieved, and In conjunction with the setting of the third gear 53 and the fourth gear 55, the center position of the mold is automatically determined, so that when the measurement angle is subsequently rotated to adjust, the mold will not be offset too much and cannot be aligned. The mold is rotated at the center of the circle, so that the force of the rotating mechanism 6 is balanced, avoiding the situation where the rotating mechanism 6 breaks or the mold falls off due to tilting and eccentricity when rotating a larger mold. There is no need for a clamping mechanism to clamp the mold, which reduces damage to the mold when it is positioned and fixed, improves the yield rate, ensures the service life of the rotating mechanism 6, and also ensures the precise alignment of subsequent measurement points, thereby improving the accuracy of subsequent measurement dimensions.

[0031] Specifically, the rotating mechanism 6 includes an electric suction cup 61, a rotating column 62, an electric push rod 63 and a plurality of limiting grooves 64. The electric push rod 63 is fixedly set on the U-shaped rack 56, and the rotating column 62 is rotatably set at the end of the electric push rod 63. The electric suction cup 61 is fixedly set on the top of the rotating column 62. The plurality of limiting grooves 64 are arranged in a ring array on the side wall of the rotating column 62, and the U-shaped rack 56 is limitedly engaged with the limiting grooves 64.

[0032] Specifically, the plurality of limit slots 64 include a plurality of arc-shaped bevel slots and a plurality of vertical slots, and the plurality of arc-shaped bevel slots are connected end to end with the corresponding plurality of vertical slots. The electric push rod 63 moves upward to drive the rotating column 62 upward, and the electric suction cup 61 contacts the bottom of the mold to adsorb the mold. The rotating column 62 moves upward to allow the U-shaped rack 56 to slide inside the vertical slot. When the rotating column 62 moves to the top, the electric push rod 63 moves downward to drive the mold downward. The synchronous U-shaped rack 56 slides inside the arc-shaped bevel slot, causing the rotating column 62 to rotate forty-five degrees. This allows the mold to be accurately aligned with the measurement point, reducing the number of fine-tuning positioning times and ensuring the accuracy of subsequent measurements. By replacing the rotating column 62 with arc-shaped bevel slots of different curvatures, the required angle can be adjusted according to different molds, which is suitable for automatically aligning the measurement point angles of the same batch of molds.

[0033] When the cam 72 is in the closed position, the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam 72 is in the closed position, and the locking cam When the mold contacts the second wedge block 77, the movement of the second wedge block 77 drives the sliding plate 75 to move, and the movement of the sliding plate 75 drives the L-shaped plug rod to move. When the L-shaped plug rod 76 is completely separated from the side wall of the L-shaped interference rod, the clamping state is released, and the gravity of the mold drives the first wedge block 73 to slide along the L-shaped interference rod until the mold stops at the interference measurement point. After the measurement is completed, the mold is removed and automatically reset by the elastic force of the reset spring 79 and the clamping spring 74; automatic measurement of the interference position of the mold is achieved, further ensuring the dimensional measurement accuracy, and indirectly improving the subsequent grinding processing accuracy. By aligning the mold at right angles, the mold can be positioned once to move the mold to the measurement point without friction with the interference point. The positioning effect is better for molds with rough surfaces that are not convenient for fine-tuning, reducing the fine-tuning steps and greatly improving work efficiency.

[0034] Specifically, the side wall of the L-shaped baffle 78 is provided with a through slot for the L-shaped rod 76 to be inserted.
